Information obtained from satellite images can be kept up-todate and a large number of classes can be distinguished. However, the quality of the information still leaves much to be desired, with a reliability of no more than 40 - 90 %. By using digitized landuse information from a topographic map as a source of contest information the reliability could be improved considerably. The method permitted the Identification of a large number of additional classes and provided quantitative insight into the dynamics of landscap change. Verification using 1:18,000 scale aerial photographs and field data showed the results to have a reliability of over 95 %. It can be expected that whereever topographic maps permit the extraction of land-use information in a similar way as described in this paper, remote sensing information will meet operational accuracy requirements for many fields of application e.g. physical planning, map udating, land-use planning etc. Paper presented at the IGARSS'88 conference ""Remote Sensing - moving towards the 21st century"" in Edinburgh, Scotland, 12-16 September 1988","remote sensing; updating; topographic map; reliability; land-use","en","report","Nationaal Lucht- en Ruimtevaartlaboratorium","","","","","","Campus only","","","","","","",""

It was found that SPOT multispectral imagery is less suitable for land use classification purposes than Landsat Thematic Mapper data due to the lack of a spectral band in the mid-infrared. The most promising approach for updating land use information on topographic maps on a raster image processing system as available at NLR, seems to be the use of digitized topographic map information at 10-m resolution together with Landsat Thematic Mapper data resampled to the same resolution. In this report, maps of change in land use are given. Such end product maps can technically be produced at a rate of 1-2 maps per week for all 120 maps sheets of The Netherlands. The main technical problem in the production of maps is the limited availability of cloudfree (summer) imagery. This availability has statistically been assessed to be once per two years on the average.","satellite imageiry; thematic mappers (Landsat); Spot (French Satellite); mapping; land use; classifications; topography; image resolution; image processing; raster scanning; geometric rectification (imagery)","en","report","Nationaal Lucht- en Ruimtevaartlaboratorium","","","","","","Campus only","","","","","","",""

HC was extracted front erythrocyte concentrates with high efficiency by HC-poor plasma or by human or bovine albyum solutions. Determination of HC in the plasma of the volunteer mainly gave insight about the concentration time course of HC bound to plasma proteins. One minute after HC injection the amount associated with erythrocytes was about half the amount bound to plasma proteins. Decrease of HC in plasma, and hence on plasma proteins, was monophasic front 30-270 rain with a half-life of 116 rain. Decrease of HC associated with erythrocytes and HC free in plasma water was biphasic from 30-270 min and initially HC diminished about five times faster from these compartments than from plasma proteins. At the end of the observation period half lives on plasma proteins, erythrocytes and in plasma water were similar, i.e., @ 120 rain. It is concluded from these as well as from previous in vitro experiments that erythrocytes gain importance as HC carriers at increasing HC blood concentrations. Once charged, erythrocytes yield HC much more readily than do plasma proteins. This ""’last come first go ’"" phenomenon of association of HC with erythrocytes is known also to exist for certain drugs.

Zo valt er bijvoorbeeld een toenemende aandacht te bespeuren voor de financiering van het onderhoud en verbetering in de particuliere sector en ook het beheer na een onderhoudsingreep wordt meer en meer benadrukt. In opdracht van het Innovatiegericht Onderzoekprogramma Bouw heeft het Onderzoeksinstituut voor Technische Bestuurskunde (OTB) een aantal van deze - in de praktijk ontwikkelde - strategieën verkend. In deze publikatie worden zij gepresenteerd, waarbij een drietal thema's wordt onderscheiden. Allereerst wordt ingegaan op mogelijke financieringsvormen voor de bekostiging van het onderhoud en verbetering van particuliere woningen. Vervolgens komt het garanderen van de kwaliteit van (complexe) beheeringrepen aan de orde. Tenslotte wordt de mogelijke rol van woningcorporaties en (door hen verstrekte) onderhoudscontracten bij het reguliere onderhoud van particuliere woningen belicht.

Allereerst is een inventarisatie gemaakt van de geïnstalleerde typen boegschroefinstallaties resulterend in een drietal hoofdtypen. Van deze typen konden kenmerkende waarden, zoals specifieke stuwkracht en verband tussen schroefdiameter en schroefvermogen worden bepaald. Daaraan gerelateerd zijn gegevens verzameld inzake uitrustingsgraad van binnenvaartschepen met boegschroeven, geïnstalleerd vermogen en type boegschroef. Vervolgens is een methode opgesteld om de uitstroomsnelheden te bepalen voor de relevante typen boegschroefinstallaties. Hierbij is gebruik gemaakt van een bestaande formule voor hoofdschroeven, welke is aangepast in verband met extra energieverliezen. Deze energieverliezen konden worden afgeschat op theoretische en praktische gronden. Daarna is aangegeven op welke wijze de stroomsnelheid tussen een varend schip en de oever kan worden bepaald. Gegeven de uitstroomsnelheden en het snelheidsveld tussen schip en oever is daarna een rekenmethode ontwikkeld om de stroomsnelheden nabij de oever te kunnen berekenen. Dit is gebeurd door het modificeren van in de literatuur vermelde formules voor stralen die uitmonden in een stromend medium. De ontwikkelde rekenmethode zorgt ervoor dat de boegstraal afbuigt ten gevolge van de optredende retourstroomsnelheden tussen het varende schip en de oever. De gehele set formules voor de berekening van de stroomsnelheid in een boegstraal op een gegeven afstand van het schip is tenslotte samengevat en toegelicht met een voorbeeld.","boegschroef; scheepsbelasting; jet; bow thruster; propeller","en","report","Deltares (WL)","","","","","","","","","","","","",""

Aandachtspunten zijn behoud van cultuurhistorische waarden en behoud en ontwikkeling van natuurwaarden, waaronder die in de getijdezone (litoraal) en de vegetaties van zoutplanten in het supra-litoraal. In dit rapport wordt geen aandacht besteed aan onderwaterbestortingen, onder meer omdat deze relatief weinig aansluitend aan de dijken in de Westerschelde voorkomen en hier andere factoren bepalend zijn voor de flora en fauna. Het integraal beheer is een relatief nieuw aspect in de benadering van zeeweringen, die primair tot doel hebben het land tegen overstromingen te beschermen. Het plangebied is de Westerschelde. Zeedijken vervullen diverse functies. Ze spelen in het landschap en het recreatiepatroon een grote rol. De rust en wijdsheid van een verblijf aan de dijk lokt plaatselijk veel recreanten. Watergebonden recreatie staat centraal. Cultuurhistorische waarden zijn vrij algemeen aanwezig. In de glooiing zijn vaak oude materialen uit het verleden aanwezig. Oude (landbouw)haventjes laten het voormalige gebruik van de kuststrook zien. De natuurwaarde wordt ontleend aan het bijzondere milieu op de dijk. Dit wordt primair bepaald door de hydralogische situatie, maar ook de mens speelt een grote rol door het beheer van het watersysteem en de materiaalkeuze bij de dijkbekleding. Er komen op het harde substraat in de getijdezone bijzondere levensgemeenschappen voor. Ze zijn nauw verwant met de flora en fauna langs de Atlantische rotskusten. In vergelijking met de Oosterschelde, waar in Nederland de hoogste natuurwaarden op hard substraat in de getijdezone worden gevonden, is de Westerschelde soortenarm. Toch vormt op nationaal niveau de Westerschelde een uitgestrekt (potentieel) habitat voor deze flora en fauna. Op verscheidene plaatsen zijn tussen de stenen op de dijk (boven de hoogwaterlijn) zoutplanten aan te treffen. Vaak is het een pover restant van wat voor de dijkverzwaringen aanwezig was. Enkele soorten komen voor op de Rode Lijst van in Nederland bedreigde planten. Dit onderzoek omvatte een inventarisatie en kartering van zowe! de natuur- als de cultuurhistorische waarden. Voor het eerste aspect is gebruik gemaakt van onderzoeksresultaten uit 1990 (litoraal). Daarnaast heeft een vegetatiekartering van rond 1980 als bron gediend (supra-litoraal). Informatie over cultuurhistorische waarden werd voornamelijk ontleend aan de diverse beheerders.","sea dikes; environmental aspects; vegetation","nl","report","Rijkswaterstaat, RIKZ","","","","","","","","","","","","",""

Uit een zeedijk met een helling 1:4 bij het Friese Blija werden grasroden gestoken en onder dezelfde helling weer ingebouwd in de Deltagoot van WL. Er zijn zeven proeven uitgevoerd, waarvan twee daadwerkelijk betrekking hadden op erosie. Deze beide proeven werden uitgevoerd met onregelmatige golven. Bij de overige vijf proeven met zowel regelmatige als onregelmatige golven lag de nadruk op de waterbeweging op het grastalud. De golfhoogten varieerden van 0,30 m tot 1,45 m. De erosiesnelheid is gemeten door de vervorming van het talud in detail te peilen. Van de waterbeweging is geregistreerd de golfoploop, de watersnelheden in oploop en neerloop, de laagdikte, en de drukklappen. Het onderhavige verslag heeft betrekking op de verwerking en analyse van de erosiemetingen en de verkregen gegevens over de waterbeweging op het talud. In een afzonderlijk meetverslag (Smith, 1993) zijn de proeven beschreven, terwijl ook golfoverslag en reststerkte is geanalyseerd. Vermeldenswaard in dit verband is verder dat een video-demo van de experimenten beschikbaar is. De analyse van de graserosiemetingen heeft geresulteerd in een praktisch bruikbare formule om de erosiesnelheid van grasbekledingen te kunnen voorspellen. De analyse van de waterbeweging op het talud heeft geresulteerd in waarden voor de golfoploop op gras van 0,81 (regelmatige golven) en 0,63 (onregelmatige golven) ten opzichte van een glad talud. Verder bleek de reductie van de golfoploop bij kleine golfhoogten (H < 0,75 m) afhankelijk te zijn van de golfhoogte. Voor de waterlaagdikten zijn ten opzichte van bestaande formules hogere waarden van de coefficienten afgeleid. Bestaande formules voor de golfklappen werden gevalideerd, evenals formules voor de watersnelheden bij regelmatige golven. Voor onregelmatige golven werden waarden voor coefficienten in formules afgeleid.","gras; waterkering; golfklap; grootschalig modelonderzoek; dijken","nl","report","Deltares (WL)","","","","","","","","","","","","TAW/ENW",""

Hand-assisted laparoscopy was therefore less time consuming than laparoscopic surgery.

A large number of journals, proceedings, patents, and books starting from the year 1991 have been consulted. The survey was completed with a thorough MEDLINE search. The survey showed that many authors have an incomplete background in the fundamentals of visual perception. This leads to a lack of understanding and to the design of supporting aids that often are not very useful. The new aspect of this study is that it gives a complete and structured overview of laparoscopic observation problems and current solutions. The observation problems are structured according to visual perception theory. The solutions are critically considered, and their benefits and drawbacks are identified. The study shows that the benefits of stereo-endoscopes and motorized endoscope positioners are questionable. The addition of shadows and movement parallax is still a very important research topic.","","en","journal article","Mary Ann Liebert","","","","","","","","Mechanical, Maritime and Materials Engineering","","","","",""

This problem may be ascribed to a lack of standards for instrument design. In this study, new ergonomic requirements for the design of laparoscopic dissection forceps were created. Three representative handles (a Karl Storz [click-line] scissors handle, an Access Plus scissors handle, and an Aesculap cylindrical handle) currently available on the market were evaluated according to the new list of ergonomic criteria. Materials and Methods: The handles were subjectively (questionnaire) and objectively (video analyses) tested in order to find out whether the new requirements are valid for the evaluation and design of instrument handles. Results: The outcome of the subjective and objective tests matched the predictions by the new criteria list. New criteria were introduced (neutral wrist excursions), and existing general criteria were specified (e.g., a minimal contact area of 10 mm). Significant differences were found among the three handles. The Storz handle met 8 of the 10 requirements, the Access handle met 5, and the Aesculap handle met only 4. Conclusions: The new list of ergonomic requirements is a valid tool to determine the ergonomic value of a handle for laparoscopic dissecting tasks. It gains its strength from its specialized character. Significant differences were found among the three tested handles. Cylindrical handles were inferior to scissors handles.","","en","journal article","Mary Ann Liebert","","","","","","","","Industrial Design Engineering","","","","",""

Structural loads. Flight handling, and mainly the subjects Flutter and Limit Cycle Oscillations and finally Store separations are addressed in this document. Analysis of structural loading of the aircraft in the external stores configurations and under the operational conditions showed no overload cases. Ventral fins were instrumented to investigate loads and vibrations due to the addition of inlet mounted pods. Comparison of configurations with the navigation pod or targeting pod, with configurations without the pods, showed increases in vibration levels; the most on the targeting pod side. As a consequence the chance of fatigue damage to the ventral fins will increase. Flight handling was analyzed and flight tests were executed. The results of this analysis were that the impact of the pod(s) on the departure sensitivity was minimal within the defined operational envelope of the aircraft. Significant deterioration was only found well outside the envelope. To verify the analysis, test flights in ""worst case"" external store configurations, without and with pods, were dedicated to verifying the flight handling characteristics. The results confirmed the analysis; in general they were judged ""satisfactory"". Configurations with substantial asymmetric loads showed unacceptable flying qualities when rolling maneuvers were initiated at negative normal load factor (inverted flight). However, such operations are excluded in the aircraft's flight manual. Simulations and earlier flight test results were used to analyse flutter and Limit Cycle Oscillation behavior. In this analysis no significant influence of the pods on the flutter / Limit Cycle Oscillation behavior was found. Further flight tests in a number of worst case configurations confirmed the analysis results. Some configurations, however, were considered not acceptable, both with and without pods, and were not certified; other configurations were certified with restricted flight envelopes. Analysis of earlier separations of 370 gallon wing pylon tanks (Royal Netherlands Air Force and United States Air Force) showed that addition of the navigation pod would have minimal effect on the tank separations. Three test flights have been executed in order to establish possible influence of inlet mounted pods on the separation behavior of wing pylon tanks. The tanks were released at identical flight conditions fi^om the left wing in three different configurations of which two with the Falcon Owl pod. All three tanks made contact with the left ventral fin on the aft fuselage of the F-16 test aircraft. The tests and analyses showed that: • The Falcon Owl navigation pod does not significantly change the trajectories of the released 370 gallon pylon tanks. • Adding the Falcon Owl pod does not affect the tank jettison limits. • The 370 gallon tank released from the left wing of a certified configuration without the Falcon Owl navigation pod struck the ventral fin in conditions under which a previous, USAF certification flight test program showed a clean tank separation from the right wing. • Because of the left tank - ventral fin interference problem new tank jettison limits are issued by USAF/SPO/F-16. The new limits are adopted for the RNLAF F-16A/B with the Enhanced Targeting Pod and the Falcon Owl Navigation Pod. The investigation into the left tank - ventral fin interference problem is a separate task, not related to the Falcon Owl pod, and of a general concern to the F-16 user community. An initial comparison of left hand and right pylon tank releases indicates that there is difference in tank separation trajectories for LH and RH tanks.

The operating surface height was defined as the level of the abdominal wall of a patient with pneumoperitoneum. Materials and Methods: Two pelvi-trainer tests were performed. One test was performed on six different operating surface heights. The (extreme) joint excursions of the shoulder, elbow, and wrist were measured by a video analysis method. Another test was performed by holding a laparoscope for 15 minutes while an electromyelograph of the biceps brachii was made. The results of both tests were evaluated subjectively by a questionnaire. Results: The ergonomically optimal operating surface height lies between a factor 0.7 and 0.8 of the elbow height of the operator/assistant. At this height, the joint excursions stay in the neutral zone for more than 90% of the total manipulation time, and the activity of the biceps brachii when holding the laparoscope stays within 15% of the maximum muscle activity. Conclusions: The operating surface height influences the (extreme) upper joint excursions of the surgeon. The ergonomically optimal operating surface height reduces the discomfort in the shoulders, back, and wrists of the surgeon during laparoscopic surgery. This optimal table height range for laparoscopic surgery is lower than those currently available.","","en","journal article","Mary Ann Liebert","","","","","","","","Industrial Design Engineering","","","","",""

It will be made clear that the disorder in the polymer films is crucial for the interpretation of the data. The field-effect transistor geometry allows variation of the charge carrier density in the semiconductor, without the presence of counter ions. Therefore, the transistor allows a rather clean study of the charge transport in organic semiconductors as a function of the charge carrier density and temperature. In the experiments we find that the organic transistors are in several respects not comparable to silicon MOSFETs. Therefore, in this thesis we redefine and re-evaluate basic transistor parameters, such as the threshold voltage, the field-effect mobility, the contact resistance and the dopant density. Subsequently, we study the charge transport as a function of charge density, temperature and electric field, giving insight into the charge transport mechanism. Based on our observations we propose as the main charge transport mechanism: multiphonon hopping of polaronic charge carriers in a Gaussian density of states. We investigate the electrical stability of the polymer layer in metal-insulator-semiconductor diodes, where we determine and analyse the dopant density changes as a function of oxygen and light exposure. The presence of contact resistances in the transistors is addressed by analysing the scaling behavior of the electrical characteristics as a function of the transistor channel length, and an empirical relation between the contact resistance and the charge carrier mobility in the polymer layer is observed. Finally, we discuss why typically only unipolar transistor behavior is observed experimentally, and we demonstrate ambipolar transistor behavior in organic field-effect transistors based on blends of organic semiconductors and on low band gap organic semiconductors.","organic semiconductor; field-effect transistor; charge transport; modelling; polymers","en","doctoral thesis","Optima Grafische Communicatie, Rotterdam","","","","","","","","Applied Sciences","","","","",""

Chapter 1 is a general introduction to this research. Chapter 2 is a more specific introduction to the metabolic biological phosphorus removal (BioP) model. The goal of this introduction is to obtain a better understanding of the stoichiometric and kinetic structure of the metabolic model and the role of the storage polymers glycogen, poly-phosphate and PHB. In chapters 3 and 4, the model is validated at full-scale conditions. Chapter 3 describes the simulation of a full-scale nutrient removing WWTP at steady state conditions. In chapter 4, the start-up of a full-scale WWTP is simulated. Under start-up conditions model kinetics can be tested more extensively than is possible at steady state conditions. In chapter 5, a method presented for data evaluation, reconciliation and model calibration. The method is tested in a full-scale simulation study. In chapter 6, all previous modelling experiences with the metabolic BioP model are evaluated. The adapted model is tested on the basis of several lab-scale experiments. The updated version of the integrated model is presented in appendix III. In chapters 7 and 8, the model is put into practice. In a case study, a process control based on the oxidation reduction potential was evaluated. On the basis of a literature study, in chapter 7 the physical meaning of measuring the oxidation reduction potential in activated sludge is discussed. In chapter 8, it is demonstrated how the model can be used for (ORP related) process control and control design.","modelling; activated sludge; biological; wastewater treatment process; biological phosphorus removal; orp control; calibration; data evaluation","en","doctoral thesis","","","","","","","","","Applied Sciences","","","","",""

(promotor)","2005","In modern semiconductor devices, only the charge of electrons is being utilized for the manipulation and transport of information. The spin degree of freedom of the electrons has not been exploited in any commercial semiconductor application so far. People in the field of Spintronics are trying to find new or improved functionalities and applications that are based on the spin of electrons, instead of - or in addition to - its charge. Some of these new ideas are based on the binary nature of the electron spin, which makes that it could serve as an elementary digital bit. When the spin state can be transported and manipulated in space and time, the spin could be used for new calculation schemes, for example. In addition, it has been predicted that the motion of electrons through materials can be affected by acting on their spin state. Hence, the spin could potentially function as a ""knob"" for tuning the conductivity of electrons. From the above it follows that it is important to understand mechanisms that allow to manipulate the spin dynamics (i.e. the spin state of electrons). The best-known mechanism to affect the spin dynamics is by an external magnetic field, i.e., via Zeeman coupling to the spin. Another potentially important mechanism is Rashba spin-orbit interaction (SOI). The interesting and distinguishing feature of Rashba SOI is, that it can be tuned by electrostatic means. This might make it easier to control the spin dynamics on very small length scales, in comparison to Zeeman coupling. Rashba SOI is also known, however, to be the main cause of spin relaxation in many 2D electron systems, thereby destroying any information that is encrypted on the spin. For the field of Spintronics it is therefore important to understand the effects of Rashba SOI, and the interplay between Rashba SOI and Zeeman coupling, on electron transport and on the spin dynamics. In this Thesis we have studied partly theoretically and partly experimentally the influence of Rashba SOI on low temperature electron transport in mesoscopic (phase-coherent) systems, such as Hall bars and ring structures. In addition, we have experimentally investigated how the competition between Rashba SOI and Zeeman coupling affects the spin dynamics in 2D electron gases, and if/how information about the resulting spin dynamics, such as the spin-relaxation time, can be obtained from ""simple"" transport measurements. Finally, we have studied the effect of the interplay between Rashba SOI and Zeeman coupling on the breaking of time reversal symmetry in 2D electron gases.","rashba spin-orbit interaction; spin dependent electron transport; interference","en","doctoral thesis","","","","","","","","","Applied Sciences","","","","",""

Session 1.2: Segregation and strategies of gating and withdrawal. Abstract: Over the years, implicitly or explicitly the relationship between spatial form and the social world has been recurrently discussed in urban studies. Recently, this topic again gained relevance through the emerging critical debate on the social consequences of gated communities. In this debate, more often than not, gated communities receive a very bad press. With reference to cities like Los Angeles, Sao Paolo, Johannesburg and Istanbul it is argued that walls and gates create exclusionary spaces that physically separate the haves from the have-nots. The lucky ones can retreat in their own spatial worlds, leaving less fortunate urban citizens behind. Spatial form thus functions to maintain and enhance social-economic inequality. On top of this, it is argued that the resulting physical separation of social groups undermines the public sphere. After all, groups that dont meet wont know and understand each other. So, the conditions for cross-social community, solidarity and maybe even democracy are under attack. We ascertain that this critical interpretation of splintering urbanism presupposes that a specific spatial form (gated enclaves) leads to specific social consequences (e.g. lack of community and solidarity) that especially hurt the disadvantaged. On theoretical grounds, we question such an elitist and spatial deterministic approach. And we prompt researchers to replace ideological reasoning on gating by precise empirical analysis of social life within gated urban fields. This paper presents a first discussion of such research conducted in Bangkok. In this Asian metropolis, not only the rich, but also the poor live behind gates. At the same time, the relational networks of inhabitants of various neighbourhoods within this splintered urban field turn out to leave space for cross-cultural encounters. However, we show that this doesnt necessitate understanding and solidarity.","Bangkok; spatial segmentation, fragmentation, respace, housing; gated community; slum; social network; public sphere","en","conference paper","","","","","","","","","","","","","",""

New Orleans provides a recent and obvious example. We analyzed the situation in New Orleans and the Mississippi Delta after hurricane Katrina has passed, from a vulnerability perspective. Vulnerability can be subdivided into four components: threshold capacity, coping capacity, recovery capacity and adaptive capacity. The vulnerability of New Orleans could be decreased by increasing these capacities. We propose Flood House as a concept to improve the four vulnerability capacities simultaneously. The Flood House is a flood-proof water management centre, in which people, science, government and business come together, first to remember victims of Katrina, but second to learn, discuss and create new - joint - ideas on all kinds of water management and flood related issues. This results in innovative strategies, policies and products to increase individual and collective safety against further future floodings. Pre-conditions for success are adaptation to local circumstances and a differentiated approach to, and platforms for, the different societal stakeholders. The Flood House facilitates an innovative approach to governance on disaster management and could therefore even have a function during hurricanes. Once it has been tested and proven itself, the concept could be transplanted to other delta regions throughout the world.","","en","report","","","","","","","","","","","","","",""

Daartoe is, in samenspraak met deskundigen, overheidsinstanties, NGO's en andere belanghebbenden, een diepgaande analyse uitgevoerd van bestaande en toekomstige problemen en hun mogelijke oplossingsrichtingen. Daarnaast is onderzocht of herinrichting haalbaar is binnen de vigerende wettelijke kaders. De werkwijze die in het project is gekozen gaat uit van een omkering van de traditionele planologische volgorde: ‘groen en blauw vóór rood en grijs’. ‘Groen’ staat voor natuur en landschap, ‘blauw’ voor waterhuishouding, ‘rood’ voor bebouwing en ‘grijs’ voor infrastructuur. De voornaamste reden voor deze volgorde is dat – in de visie van de opstellers van dit rapport – collectieve, veelal ongeprijsde goederen voorrang verdienen in de ruimtelijke inrichting, omdat ze anders het onderspit dreigen te delven in het spel der vrije marktkrachten. En dit terwijl ze wel degelijk een grote maatschappelijke waarde vertegenwoordigen. Het belang van deze werkwijze wordt onderstreept door de volgende ontwikkelingen: Het ‘groene’ thema wordt steeds meer bestreken door strenge regelgeving. Ten eerste de Europese Vogel- en Habitatrichtlijn, in Nederland uitgevoerd door de recente renovatie van de Natuurbeschermingswet. Hierdoor is het behoud van natuurwaarden in IJsselmeer, Markermeer en IJmeer een gegeven geworden. Ten tweede wordt momenteel de Kaderrichtlijn Water ingevoerd, die uitgaat van een grote mate van natuurlijkheid van oppervlaktewateren. In het ‘blauwe’ thema wordt de klimaatverandering een grote factor van betekenis. Dit gaat ingrijpende gevolgen hebben voor de manier waarop het IJsselmeergebied beschermd moet worden tegen overstromingen en voor het zoetwaterbeheer, waarin het IJsselmeergebied een belangrijke rol speelt.","Delft Cluster; CT04.40; ontwikkeling van wetlands; CT04.41.11; wetlands in het IJsselmeer; ruimtelijke ordening; ruimte voor de rivier","nl","report","Delft Cluster","","","","","","","","","","","","",""

This preparation often reduces the uncertainty or reveals the structure of the problems and processes to be dealt with. A complex problem becomes less complex for those involved in solving it. This is the eye of the beholder. An experienced eye will perceive a different level of complexity than an inexperienced. However we cannot say, less complexity for the experienced, more for the inexperienced. Inexperienced observers may overlook, thus underestimate complexity. The goal of this thesis is to show that structure is one of the most important and often overlooked design variables in solving complex business management problems.

The partial discharge detection system uses narrow-band detector, in this case a spectrum analyzer. This technique however is very difficult to calibrate due to different factors affecting the frequency response of the measuring setup. This paper also presents a sensitivity check which can be used to validate the sensitivity of the system for a certain required PD level.

(contributor); Soes, D.M. (contributor); Beuker, D. (contributor); Van Wieringen, M. (contributor); Donicie, L. (contributor); Bureau Waardenburg bv","2007","De komende jaren is groot onderhoud gepland aan de beide havenhoofden bij IJmuiden. Hierbij zullen nieuwe betonblokken op de havenhoofden worden aangebracht. De havenhoofden behoren tot de vijf belangrijkste overwinteringsgebieden in Nederland voor de paarse strandloper. Deze soort foerageert op en tussen de betonblokken. Een grootschalige vernieuwing van de blokken heeft wellicht een negatief effect op de paarse strandloper, terwijl er geen alternatieve foerageergebieden in de omgeving beschikbaar zijn. In oktober 2004 zijn ongeveer 30 proefblokken neergelegd op de kop van het zuidelijk Havenhoofd. Rijkswaterstaat Noord-Holland is geïnteresseerd in de aangroeisnelheid van wieren en macrofauna op de nieuwe blokken, waarbij de oude blokken, die in 1967 zijn geplaatst, als referentie dienen. Beantwoording van deze vraag is van belang voor het vaststellen van de fasering van het geplande groot onderhoud. Indien de aangroeisnelheid van wieren en macrofauna relatief laag is, kunnen bij grootschalige aanpak van het onderhoud de foerageermogelijkheden voor de paarse strandloper tijdelijk geheel verdwijnen, terwijl de steenloper mogelijk negatief wordt beïnvloed. Om na te gaan welke organismen op het menu van de paarse strandloper staan en met welke snelheid nieuwe betonblokken begroeien, is in april 2006 veldonderzoek uitgevoerd. Enerzijds is gekeken naar aanwezigheid, gedrag en voedselkeuze van de paarse strandloper en steenloper en anderzijds is de begroeiing van nieuwe betonblokken van 1,5 jaar oud vergeleken met die van betonblokken van bijna 40 jaar oud. Het onderzoek is, met enkele aanpassingen, in december 2006 herhaald. Op grond van de resultaten van het onderzoek kunnen de volgende aanbevelingen worden gedaan ten aanzien van het groot onderhoud aan de Zuid- en Noordpier: - De werkzaamheden aan de pieren dienen in de periode half mei-augustus plaats te vinden. - De hellingshoek van de vlakken van de blokken mag niet te steil zijn, omdat de vogels dan niet goed in staat zijn om op de blokken te foerageren. - De werkzaamheden over de pieren dienen minstens een spreiding te hebben van drie jaar, omdat een deel van de potentiële prooisoorten minstens twee jaar nodig heeft om zich weer op de pier te kunnen vestigen. Aangezien de vogels vooral aan de buitenzijde van de pier foerageren, geldt dit met name voor de buitenzijde van de pier. - De vogels foerageren bij voorkeur in de hoogtezone tussen NAP en -0,8 m NAP: een minder steil talud in deze hoogtezone is gunstig voor de paarse strandlopers en steenlopers. - De belangrijkste voedselsoorten voor deze vogels zijn de adulten en vooral larven van de dansmugsoort Telmatogeton japonicus, ruwe alikruiken en mosselen. Bij het ontwerp en materiaalgebruik moet ten behoeve van de vogels de aanwezigheid van deze prooisoorten behouden/bevorderd worden. - In de zone boven NAP worden op de bovenzijde van de blokken vooral larven van de dansmugsoort Telmatogeton japonicus geconsumeerd en geen mosselen en ruwe alikruiken, omdat deze soorten hier ontbreken. Deze soorten komen wel voor op de zijkanten van de blokken. Door ruimte tussen de blokken aan te brengen, kunnen de vogels ook op deze prooisoorten foerageren. - De aanwezigheid van ruwe alikruiken wordt ter plaatse vooral bepaald door de beschikbaarheid van holten/gaatjes in het oppervlak van de blokken. Het is daarom aan te bevelen om reeds bij de fabricage holten te creëren. Een diameter van 20-30 mm en een diepte van 10-15 mm wordt al geschikt geacht voor de holten. Uit kostenoverwegingen zouden blokken met gaatjes en langsgroeven pas vanaf de 3e rij (vanaf de bovenkant pier gezien) toegepast kunnen worden.","pier IJmuiden; paarse strandloper; steenloper; flora; Fauna; betonblokken; vegetatie","en","report","Rijkswaterstaat, Noord-Holland","","","","","","","","","","","","","52.458343, 4.537534"

(promotor)","2007","Infrastructures, generally designed to have a long service life, are particularly vulnerable to long term changes that can influence their functioning. Therefore it is important that uncertainties are taken into account as much as possible from the beginning of the planning process of infrastructures. This thesis focuses on drinking water infrastructure. This type of infrastructure is characterized by a long life expectancy. Changes in the supply of materials (for instance source water, energy, space for building underground networks), technology, and demand for the end product can be expected, but are difficult to predict. These changes can lead to high cost for society when they lead to system failure or obsoleteness of the existing infrastructure. The main objective of the research was to answer the following question: Can the identification and handling of uncertainties in the Dutch drinking water infrastructure planning process be improved? And if so, how? To answer this question, first a literature study was performed, which was used as a basis to develop both a descriptive and a normative framework for the analysis of case studies. These frameworks then were used to analyze four case studies ex post. Finally, a workshop was used to discuss the overall results with representatives from the drinking water field. The descriptive framework is based on an approach in which a system is described as well as the influences on that system. These influences can come from external variables that cannot be influenced by a decision-maker and from tactics that a decision-maker can use. The effect of both on the system can be observed in changes in the outcomes of interest that a decision-maker has. The normative framework was developed to evaluate the success of drinking water companies in their efforts to deal with uncertainty. It is based on a causal chain of actions in a planning process that should lead to successfully dealing with uncertainty. It was chosen to use indicators of success within the causal chain as proxies for the overall success of a drinking water company in dealing with uncertainty. For each step in the causal chain a indicator of successfully performing this step was identified. The idea was that if each step is performed well, overall success in dealing with uncertainty will follow. Four cases were studied in retrospect, of which three were recent and one was further in the past. The most important conclusion of the cases was that drinking water companies are very aware of uncertainties and a lot of action is taken to handle them. However, some suggestions can be made to improve the analysis and handling of uncertainties. Firstly, the case studies showed that not all potential critical external influences received the same amount of attention. Political, social en technological considerations were found the most crucial in the cases that were studied. Political and social influences were also found to be most difficult to handle. Secondly, some external influences were recognized in the cases, but were not included in the analysis, because not enough was known about them. For instance in the case of the success of drinking water saving actions this external variable showed to be critical. If this influence would have been considered in more detail maybe other decisions would have been made. Thirdly, the cases showed that assumptions were made more explicit after they had failed. If they had been made more explicit beforehand maybe decisions to change policy could have been made sooner.","uncertainty analysis; drinking water infrastructure; planning","en","doctoral thesis","","","","","","","","","Technology, Policy and Management","","","","",""

(contributor)","2008","In de afgelopen twee eeuwen zijn er drie perioden geweest, waarin relatief veel werd geesteerd in infrastructuur. Dit had te maken met grote nationale projecten die in de betreffende periode werden uitgevoerd. In de periode tussen 1865 en 1880 was de investeringsquote hoog vanwege de gelijktijdige aanleg van de Nieuwe Waterweg en het Noordzeekanaal, terwijl in die zelfde periode ook veel werd geesteerd in nieuwe spoorwegverbindingen. Tussen 1920 en 1940 waren de investeringen substantieel hoger dan in voorafgaande decennia vanwege de Zuiderzeewerken. Na 1953 zorgden de Deltawerken voor een langdurige periode van hoge infrastructuurinvesteringen. In de jaren zeventig en de eerste helft van de jaren tachtig liep de investeringsquote terug tot tussen de 2 en 2,5% van het bbp. Sindsdien schommelt zij rond dat niveau (zie figuur 5.1). Waarom zijn de investeringen in infrastructuur in de ene periode hoger dan in de andere? Terugkijkend over de afgelopen twee eeuwen waren er altijd urgente redenen om het investeringsniveau in een bepaalde periode op te schroeven. In het midden van de negentiende eeuw werd steeds duidelijker dat de Nederlandse economie achterop dreigde te raken bij omringende landen. De havens van Amsterdam en Rotterdam verloren steeds meer marktaandeel aan Antwerpen en Hamburg. Er moest iets gebeuren. In de jaren tien en twintig van de vorige eeuw waren voedseltekorten (eerste wereldoorlog) en overstromingen (1916) reden om de al langer bestaande plannen tot indamming van de Zuiderzee door te zetten. De Watersnoodramp van 1953 was de directe aanleiding voor de Deltawerken waaraan bijna vijftig jaar is gewerkt. Zowel bij de indamming van de Zuiderzee als de Deltawerken waren overstromingen noodzakelijk voordat het besluit werd genomen om bestaande plannen uit te voeren. Bij de Zuiderzeewerken waren er al vanaf 1850 plannen ontwikkeld, maar pas na de overstroming in 1916 werd de Zuiderzeewet (1918) aangenomen. Vde Deltawerken was er ook al 25 jaar gewerkt aan plannen om de zeearmen af te dichten. Dit leidde in waterstaatkundige kringen soms tot frustratie. Volgens de anekdote verzuchtten de ingenieurs bij Rijkswaterstaat regelmatig: Geef ons heden ons dagelijks brood, en af en toe een watersnood. Ook bij het Noordzeekanaal en de Nieuwe Waterweg duurde het lang voordat er een sense of urgency ontstond, maar hier was het vooral de voortdurende verslechtering van de concurrentiepositie van de havens van Amsterdam en Rotterdam die de doorslag gaf om kostbare infrastructuurprojecten te ondernemen. Grote waterstaatkundige en infrastructurele werken zoals die in dit essay zijn beschreven, gaan gepaard met fundamentele onzekerheid. Altijd zullen er twijfels zijn over nut en noodzaak. De financi en technische haalbaarheid zullen worden betwist. Kosten en baten blijken over een zo lange periode onmogelijk te voorspellen. De enige zekerheid is dat dergelijke grote werken diep ingrijpen op de leefomgeving, de economie en de samenleving. Zij geven het land vorm op een wijze die tot in de verre toekomst merkbaar blijft.","hoogwaterbescherming,; historie","en","report","Nyfer","","","","","","","","Civil Engineering and Geosciences","","","","",""

Developments in the building regulatory systems are being placed within the context of general trends in the regulatory sciences, particularly with reference to Europeanization studies. Within the regulatory sciences, there is broad consensus about the trend towards deregulation and privatisation in recent decades. Studies conducted under the rubric of ‘Europeanization’ analyse the effects of European policies on the policy frameworks of the member states in more detail. The results so far show that building control tasks are more and more privatised and administrative procedures are under the influence of deregulation processes. The influence of the European Union is especially recognizable in developments regarding the content, scope and formulation of technical requirements. In the end of last year we started a major new European comparative research project to actualize and expand our knowledge. In this new project the regulatory systems of all European countries will take be taken into account. Three main subjects are being addressed: The position of building regulations within the legislative system. The scope of technical requirements that regulate the minimum quality level for buildings. The building permit procedures and the system of building control. This paper highlights the results from previous projects and presents the research framework and the first considerations on the three main subjects of this ongoing research project.

Technical regulations and control seems to be the subject of an ongoing debate between, on the one hand, those in favour of deregulation and reducing the administrative burden and, on the other hand, new quality demands that require government intervention. Currently in the Netherlands, both sides of this debate appear to be gaining in importance. Deregulation, as well as high targets for energy conservation, structural safety and reliable government are high on the politicians’ agenda. The desire for deregulation is leading to the opinion that greater emphasis should be placed on the responsibility of property owners, which could lead to less government intervention. However, the existing forms of quality control for private actors in the Dutch building industry seem to be of quite a low standard. Accidents occur and physical quality does not appear to be sufficiently important. As the CO2 and energy saving targets increase, stronger regulations and accurate building control become a priority. The paper addresses these developments. It presents an analytic model for systems of building control based on examples from European countries and conclusions and recommendations for developments in the Netherlands and possibly in other European countries.","Building Regulations; Housing Quality; Building regulations; Europe","","conference paper","Royal Institution of Chartered Surveyors Dublin Institute of Technology","","","","","","","","OTB Research Institute","","","","",""

The complete interface has been designed and implemented as an integrated circuit, using standard 0.7 ?m CMOS technology. Experimental results, which are in good agreement with theoretical analysis and simulation, show that for sensor capacitance down to 10 pF, shielded connection cables up to 30 m can be handled with an absolute error of less than 0.3 pF. The measured nonlinearity of the interface amounts to about 3 × 10?4 for 30 m of the cable.

In verschillende studies, workshops en beleidsdocumenten is aan dit peilbeheer gerefereerd en gerekend. Aan Deltares is gevraagd te verkennen in hoeverre de wensen ten aanzien van het seizoensgebonden peil vanuit natuur en zoetwatervoorzieining en de effecten daarvan op diverse aspecten en gebruiksfuncties bekend en gekwantificeerd zijn en hoe deze kennis eventueel in vervolgstudies verder is aan te vullen. Dit rapport beschrijft het resultaat van deze inventarisatie. De focus is hierbij geweest op het IJsselmeer en het Markermeer. De Veluwerandmeren zijn buiten beschouwing gelaten. Een seizoensgebonden peil kan door inundatie van oeverzones in het vroege voorjaar en het vervolgens weer droogvallen tijdens het groeiseizoen een grotere diversiteit aan vegetatie en daarmee meer diverse habitats bewerkstelligen. Deze versterking van natuurwaarden kan in het IJsselmeer en het Markermeer alleen plaatsvinden wanneer ook grootschalige landwaterovergangen worden gerealiseerd; het talud van oeverzones bepaalt immers hoeveel land inundeert en weer droogvalt. Een variatie door het seizoen van 65 tot 100 cm lijkt wenselijk. Natuurwaarden hebben echter baat bij afwijkingen van deze variatie door de jaren heen. Voor nieuw te ontwikkelen natuur moet het talud en de hoogteligging van de oevers worden afgestemd op het in te stellen peilverloop. Het instellen van een structureel hoger of lager peil zal invloed hebben op bestaande natuurwaarden. Een afweging waarin alle natuurwaarden worden meegenomen is nodig. Peilveranderingen hebben ook invloed op waterkwaliteit (slibopwerveling, temperatuur, nalevering uit de bodem) en waterkwaliteit en natuurwaarden beïnvloeden elkaar. Het is raadzaam om de waterkwaliteitseffecten op natuurwaarden mee te nemen in een verdere bepaling van het voor natuurwaarden gewenste peilverloop. Voor zoetwatervoorziening verwacht het W+ klimaatscenario een vraag naar extra water (in 2050 ongeveer 50 cm waterschijf in IJsselmeer en Markermeer in een extreem droog jaar), waarin door middel van seizoensfluctuaties voorzien kan worden. Hierbij wordt juist gevraagd het peil tot ver in de zomer (juli, augustus) hoog te houden. Uitgangspunt is om voor het instellen van een seizoensgebonden peil geen dijkverhoging te laten plaatsvinden. Veiligheid bepaalt daarmee de bovengrens voor het instellen van een seizoensgebonden peil. In het vroege voorjaar (maart/april) kan op het IJsselmeer tot 2020 het peil tot - 0,05 m NAP verhoogd worden, tot 2035 kan dit tot -0,10 m NAP (vanaf april). Voor het Markermeer geldt een mogelijke opzet tot -0,10 m NAP tot 2020, tot 2035 kan het peil tot ditzelfde niveau worden opgezet, echter wel pas in april. Voor alle situaties geldt dat vanaf mei het peil verder opgezet kan worden tot + 0,10 m NAP op het Markermeer (zowel 2020 als 2035) en het IJsselmeer tot 2035. Tot 2020 kan op het IJsselmeer in mei tot +0,15 m NAP worden opgezet.","peilbesluit; peilbeheer; IJsselmeer; Markermeer","en","report","Deltares","","","","","","","","","","","","",""

The project compares the systems of building control, the formulation of regulations, and the content of requirements for selected subjects and only for the domain of housing. Earlier (Visscher e. a. 2005) an article about the differences in the systems of formulation of regulations was published.

De eisen dienen meerdere doelen zoals de bescherming van de belangen van eigenaren en gebruikers van gebouwen, van derden maar ook van maatschappelijke belangen. Voorschriften hebben alleen betekenis als ze ook gehandhaafd worden. De naleving van voorschriften in het Nederlandse bouwproces laat te wensen over gezien de problemen met constructieve veiligheid en indicaties over achterblijvende energieprestaties van gerealiseerde gebouwen. De voorschriften voor energieprestaties en in het verlengde daarvan voor gezondheid, zullen in de komende jaren strenger worden. We kunnen constateren dat het belang van een betrouwbaar systeem voor het verzekeren van de naleving van de voorschriften groot is en aan belang toeneemt. Wij zijn ervan overtuigd dat naleving alleen kan worden gegarandeerd als er expliciete toetsen worden uitgevoerd op het ontwerp, toezicht tijdens de uitvoering en een inspectie van de opgeleverde gebouwen. Deze toetsen, het toezicht en de inspectie kunnen worden uitgevoerd door de gemeente, door onafhankelijke private bureaus en door de uitvoerders van de primaire processen (architect, adviseur en bouwbedrijf). Gezocht moet worden naar een optimale verdeling van taken en verantwoordelijkheden zodat de zekerheid op naleving wordt gegarandeerd en tevens de regeldruk door procedures en dergelijke geminimaliseerd wordt. Het huidige stelsel van preventieve toetsingen in het kader van de bouwvergunning en het toezicht op de uitvoering door de gemeenten wordt vaak ervaren als een stelsel dat voor een te grote regeldruk zorgt. De rechtstreekse doorwerking van de voorschriften van het Bouwbesluit zou de betekenis van de preventieve toets door gemeenten uithollen. Na een lange voorbereidingstijd is sinds enige maanden het procescertificaat voor de Bouwbesluittoets beschikbaar. Deze wordt momenteel door verschillende gebruikers op basis van afspraken in een convenant geaccepteerd als alternatief voor de traditionele gemeentelijke toetsing. De minister van WWI heeft de intentie uitgesproken om de Gecertificeerde Bouwbesluittoets ook wettelijk te verankeren. Dit roept de vraag op wat het effect daarvan zal zijn op de verdeling van verantwoordelijkheden tussen gemeenten en gecertificeerde toetsbureaus, als de preventieve toetsing nog steeds onderdeel uitmaakt van de bouwvergunning. Deze ontwikkelingen maken de vraag urgent wat een optimaal model om de naleving van het Bouwbesluit zeker te stellen. s het model werkbaar waarin een aanvrager kan kiezen tussen een preventieve technische toets uitgevoerd door een gecertificeerd bureau óf uitgevoerd door de gemeente, een zogenaamd duaal stelsel (model I)? Voordeel van dit stelsel is de marktwerking die kan ontstaan tussen verschillende partijen en de gemeenten. Dit kan een positief effect hebben op de kosten en ook op de kwaliteit, mits er voldoende supervisie op het systeem blijft bestaan. Er zijn veel landen waar zo’n systeem bestaat en de ervaringen zijn redelijk positief. Voordeel is dat er ook technische expertise blijft bij de gemeenten. Nadeel is dat, doordat een deel van het werk bij de gemeenten weg zal gaan het moeilijker zal zijn om de resterende taken in te vullen. Als gekozen wordt voor dit model is het zinvol om het gepaard te laten gaan met enkele aanvullende maatregelen. In de eerste plaats dient in het geval dat een private partij de technische toetsing uitvoert, de gemeente geen enkele verantwoordelijkheid meer te hebben voor dit deel van de toets. Het model wint aan helderheid als de technische toets ook totaal uit de omgevingsvergunning verdwijnt. In plaats daarvan dient men om te kunnen bouwen wel over een Bouwbesluitgoedkeuring te beschikken. Deze kan worden verstrekt door gecertificeerde bureaus of door gemeentelijke diensten. Om voldoende kwaliteit en capaciteit te kunnen bieden is het zinvol dat gemeenten samen regionale diensten opzetten. Ook voor het toezicht op de uitvoering kan worden gekozen tussen publieke en private partijen. Het systeem wint aan helderheid en kwaliteit als de opdrachtgever één partij kan kiezen die zowel het ontwerp toetst als toeziet op de uitvoering. Het proces zou moeten worden afgesloten met een opleveringstoets alvorens het gebouw in gebruik genomen mag worden. Met name voor energie en binnenklimaat is dit van groot belang. Bovendien geeft dit de eigenaar meer zekerheid over het voldoen aan voorschriften. Een helderder model kan ontstaan als ervan uit wordt gegaan dat gemeenten in het geheel geen preventieve technische toetsen en uitvoeringstoezicht meer uitvoeren, maar wel kunnen beslissen over de invulling van het controleproces door de private partijen (model II procescontrole). Voordeel is dat private partijen veel meer dan bij model I gedwongen worden om toetsing- en toezichtprocessen te ontwikkelen. Gemeenten hoeven geen feitelijke technische controles meer uit te voeren maar kunnen zich specialiseren in supervisie op de procedures van de private partijen. Het model heeft goede perspectieven voor zowel de kwaliteit van toetsingen en toezicht als voor de efficiëntie van de procedures. Belangrijke voorwaarde is wel dat er een heldere basis is voor gemeenten om te beoordelen welke partijen instaat zijn om op voldoende niveau te kunnen toetsen en het toezicht uit te voeren. Het is raadzaam dat er nationale criteria worden vastgelegd. Als dit alleen kan op basis van het procescertificaat voor de Bouwbesluittoets in combinatie met een vergelijkbaar procescertificaat voor het toezicht op de uitvoering, dan zal er geruime tijd over heen gaan voordat er voldoende bedrijven zijn die het kunnen uitvoeren. Bovendien, op basis van een nationaal certificaat hoeft een gemeente niet nadrukkelijk naar het ‘controleplan’ te kijken. De rol van de gemeente is met name van belang om toe te zien op de toedeling van verantwoordelijkheden over alle betrokken partijen. In een andere variant mogen partijen ook een niet gecertificeerd systeem aan de gemeente voorstellen. Per situatie oordeelt de gemeenten of dit voldoet. Indien er te weinig vertrouwen is, kan de gemeente een externe partij aanwijzen die de toetsing en het toezicht moet uitvoeren. Voordeel van het systeem is dat de private partijen worden aangespoord om kwaliteitszorg door te voeren. Er is een heldere verdeling van verantwoordelijkheden. Het kan alleen tot een verbetering van de kwaliteit van toetsing en toezicht leiden als de overheid hoge eisen blijft stellen aan de toetsing- en toezichtprocessen die de private partijen hanteren. Als voor dit model wordt gekozen is het zinvol om aan te kondigen dat over bijvoorbeeld twee jaar het vernieuwde stelsel operationeel zal zijn. In de tussentijd kunnen bedrijven de interne kwaliteitszorg verder ontwikkelen. Tevens moet er aandacht zijn voor de positie van kleine bedrijven. Tenslotte kan worden gedacht aan een situatie waarin geen voorwaarden worden gesteld aan de toetsingsprocessen en de organisatie van het toezicht. De eigen verantwoordelijkheid van eigenaar en uitvoerende partijen wordt sterk benadrukt. De handhaving van het systeem moet worden gerealiseerd door een inspectie bij de oplevering en de mogelijkheid dat de gemeente handhavend optreedt als er niet wordt voldaan aan de voorschriften (Model III: handhaving achteraf). Het model biedt een heldere verdeling van verantwoordelijkheden en maximale deregulering. Wij hebben grote twijfels over dit model. Er zijn ons geen voorbeelden uit andere landen bekend van zo’n model (hoogstens voor eenvoudige bouwwerken). Zelfs in het Franse systeem waar erg wordt geleund op aansprakelijkheid en verzekeringen, is het voor grotere bouwwerken wettelijk verplicht om een extern controlebureau te betrekken. Om een bouwwerk op te leveren dat voldoet aan de eisen van het bouwbesluit zijn controles gedurende het gehele proces noodzakelijk. Achteraf zijn niet alle fouten te constateren en niet of alleen met grote kosten te herstellen. Het model kan alleen functioneren als de private partijen op grote schaal meer gaan doen aan kwaliteitszorg. Op zijn minst moet er bijvoorbeeld weer toezicht namens de opdrachtgever op de bouw worden uitgevoerd. Hoofdconstructeurschap moet zeer serieus worden genomen. Een architect kan alleen zijn titel verkrijgen als hij heeft aangetoond de verantwoordelijkheid te kunnen dragen om ontwerpen af te leveren die aan het Bouwbesluit voldoen. Ook beroepsorganisatie kunnen een belangrijke rol spelen bij het verhogen van de kwaliteitseisen van hun leden. En ook opdrachtgevers moeten zich goed bewust zijn van hun verantwoordelijkheid. Kortom: behalve een kleine aanpassing van de Woningwet vergt zo’n verandering een cultuuromslag in de bouwsector. Voor de Nederlandse situatie bieden model I en model II de beste perspectieven. Model II zou kunnen worden aangemerkt als het model dat over enige tijd wordt ingevoerd. Door een wettelijke erkenning van de Gecertificeerde Bouwbesluittoets kan in de tussentijd model I functioneren. In de transitieperiode zullen initiatieven moeten worden genomen om kwaliteitszorg meer in het bouwproces te integreren. Ook moet er specifiek worden gekeken naar de kleine bouwwerken. Deze maken in aantal en tijdsbesteding een groot deel uit van behandeling door gemeenten. Veelal is er een niet professionele opdrachtgever (eigenaar-bewoner). Voor een groot deel van deze projecten (aan- en verbouwingen) ligt er een mogelijkheid om de energieprestatie van gebouwen te verhogen. Voor deze projecten zou de rol van de gemeente in het proces ook gelegen kunnen zijn in het wijzen op mogelijkheden van het nemen van energiebesparende maatregelen. Dit sluit aan bij de intenties van het Meer met Minder programma.","","nl","lecture notes","Instituut voor Bouwrecht","","","","","","","","OTB Research Institute","","","","",""

To guarantee that these requirements are applied, a building control system is indispensable. The trend towards a common market for construction products and services justifies gaining better insight into the building control systems in the European Union. This paper presents a comparison of the tasks and responsibilities of public and private parties in the building control systems of the 27 European Union countries. To gather the necessary information, a questionnaire on building regulatory systems was distributed to national experts in each country, and the major legal documents were reviewed. The information was organized in thematic tables that contain all the countries. The themes are as follows: regulatory framework, application, plan approval, site inspection, completion and supervision. The main conclusion is that the building control systems of EU countries have many similarities. Public parties set the regulatory framework, check planning demands, issue building permits, conduct final inspections, grant completion certificates and supervise the system. The main difference concerns the involvement of private parties in checking technical requirements and in site inspections. Three basic types of building control systems were identified: public building control, mixed building control and dual building control. The majority of the countries have mixed systems. Although several variations were found among the mixed systems, the most common situation is for public parties to check the technical requirements and private parties to be involved in site inspections. Additional uniformity among building control systems would help to support a single market for services in the construction industry, in which architects, developers and builders are no longer limited to working within national markets.","building control system; comparative study; European Union","en","conference paper","RCIS","","","","","","","","OTB Research Institute","","","","",""

The losses can be significantly reduced by adapting the solar spectrum. A promising avenue is the use of a downconversion material where one higher energy visible (blue-green) photon is “cut” into two lower-energy near-infrared photons that both can be used by the solar cell. Here the efficiency of downconversion for the (Nd3+,Yb3+) couple in YF3 is studied to investigate if efficient two-step energy transfer occurs from the 4G9/2 level of Nd3+ (situated around 21?000?cm?1 or 470 nm) exciting two neighboring Yb3+ ions to the 2F5/2 level (around 10?000?cm?1 or 1000 nm). Optical measurements of YF3 doped with Nd3+ and Yb3+ show that there is efficient energy transfer from Nd3+ to Yb3+, but downconversion from the 4G9/2 level does not occur due to fast multiphonon relaxation. Relaxation from this level to lower-energy levels populates the 4F3/2 level of Nd3+ from which efficient one-step energy transfer to Yb3+ occurs. Analysis of the luminescence decay curves for different Yb3+-concentrations using Monte Carlo simulations reveals a high nearest neighbor transfer rate (3.3×105?s?1) through a dipole-dipole interaction mechanism. Downconversion is observed from the 4D3/2 level (situated in the UV, around 28?000?cm?1 or 360 nm) with an estimated quantum efficiency up to 140%. For application in solar cells this UV to 2 NIR downconversion will only result in a marginal reduction of spectral mismatch losses.","","en","journal article","American Physical Society","","","","","","","","Mechanical, Maritime and Materials Engineering","Process and Energy","","","",""

Three research questions are addressed: what are the main differences and similarities? what are the main types of organization and formulation? what are the main trends and developments? The following tasks were carried out in order to provide an answer to these questions: preparing a questionnaire and obtaining answers from experts of EU countries, collecting and analysing main building regulations, and comparing results. The results are that, in the majority of the EU countries, central authorities are involved in setting technical building regulations, however the involvement of regional and local authorities varies. Technical building regulations can be set in one main document, a coordinated group of documents or separated legal documents. The formulation adopted for most subjects is performance based, combined with functional or prescriptive requirements for specific subjects. Only in England and Wales have technical building regulations a pure functional formulation. Few countries have official documents with deemed to satisfy solutions. The building regulations include the main subjects (i.e. safety, health, practicability and energy saving), but several countries have no requirements on environmental protection. In the majority of the EU countries, direct references to specific standards are made, but standards are not accessible free of charge. There is not a pattern in the way that building regulations apply to construction works in existing buildings. The main conclusions drawn from the study were that there are five main types of organization and formulation of technical building regulations in the EU countries, as follows: 1) one document with functional requirements and a coordinated group of documents with deemed to satisfy solutions; 2) one document with performance requirements; 3) one document with prescriptive requirements and new performance regulations on specific subjects; 4) a set of coordinated documents with performance requirements; and, 5) separated legal documents mainly with performance requirements combined with some prescriptive requirements. Although there are exceptions, a regional distribution was observed in the countries that adopt each type.","technical building regulations; comparative study; European Union","en","conference paper","University of Salford","","","","","","","","OTB Research Institute","Housing Quality and Process Innovation","","","",""

It is recognised that to achieve these goals the energy saving potential idling in the existing housing stock must be exploited. To date the Dutch response is largely defined by the typical national repertoire of policy instruments including voluntary agreements, economic incentives and information campaigns. Alongside this, the Energy Performance Certificate (EPC) required under the Energy Performance of Buildings Directive has entered the fold. Despite a controversial arrival and a low impact on much of the intended target group this tool is entering a new phase in Dutch policy circles. By providing an overview of the Dutch situation, this paper offers a contribution to the much-needed debate on policy instruments utilised to improve the energy performance of existing housing. Using policy instruments as a lens and drawing on stakeholder interviews, the Dutch national response to harnessing the energy saving potential of the existing housing stock is evaluated. Stakeholder interviews demonstrate consensus that the usual suspects from the policy toolbox are inadequate. Consensus on what an adequate toolbox should consist of is less forthcoming. Within this debate the EPC is materialising as a core component. But can manipulations of the EPC wake the sleeping giant that is the energy guzzling existing housing stock?","energy performance certificates; existing housing stock; policy instruments; evaluation","en","conference paper","ECEEE","","","","","","","","OTB Research Institute for the Built Environment","OTB Research","","","",""

To address these shortcomings, the paper proposes a new topological structure that consists of two 3-dimensional spaces: Product-space and Social-space. The P-space is constructed by the complexity of the artifact, the number of disciplines involved and the availability of knowledge. The S-space consists of the number of disciplinary languages, number of different perspectives and the amount of openness and closeness of the social system that encapsulates the design activity. The two spaces are connected by means of theories on cognition, like: individual and distributed cognition, socio-linguistics, situated cognition, etc. Two examples serve to illustrate the proposed model and show that the act of designing involves the evolution of the artifact, social system, language and information embedded in the social and societal context.","cognition; design theory; empirical studies; designing","en","conference paper","The Design Society","","","","","","","","Industrial Design Engineering","Product Innovation Management","","","",""

The information was organized in thematic tables containing all the countries. The main conclusion is that the organization of a regular building permit procedure is similar in the EU countries. No major differences were found concerning the several steps it takes to get a building permit and to carry out a construction work: pre-consultation, possibility of phasing, submission demands, checks carried out and maximum procedure time for plan approval, possibility and moment to object to a building permit being issued, start of construction works, frequency and moment of site inspections, fees, and completion of construction works. The main differences concern detail aspects in several of these steps. There is one basic type of building permit procedure in countries from continental Europe. The United Kingdom countries are those presenting more deviations from the common pattern. These deviations aim to reduce the burden of administrative aspects, while ensuring good levels of compliance. In the last 10 to 15 years, the dominant trends identified in the building permit procedure were a decrease in the types of construction works submitted to building authorities’ control during plan approval, and the reduction in the maximum building permit procedure times. Building authorities’ control during the construction phase has remained unchanged. Altogether, there is a movement towards simpler and faster building permit procedures. For the near future, no major changes are expected in the building permit procedures.","building control system; building permit procedure; comparative study; European Union","en","conference paper","Royal Institution of Chartered Surveyors","","","","","","","","OTB Research Institute for the Built Environment","OTB Research","","","",""

Real-world application in seven cases has shown that the actual purpose of low-tech and high-tech games does not differ so much, but that the level of detail in the quantitative data yielded is much better in the high-tech games, as can be expected. Low-tech games however have shown a good purpose in questions where multiple types of roles had to be present. Connecting them to high-tech games requires other components that have long development times. Even though these modules are currently under construction, the low-tech games continue to fulfill their purpose due to their capability of stylized representation of systems and data.","gaming simulation; traffic control; process innovation; fidelity","en","conference paper","","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

This paper is about innovative measures at a railway network operator, required to increase capacity on the railway network without investing in expensive infrastructural extensions. Using field observations and open interviews, the authors found out that project managers early on in the decision-making process limit their design space. The range of alternatives under study is limited to decrease the technical and social complexity. By doing so, project managers are able to realize a phased and sequential decision making process that leads to a working proof-of-concept. The solutions are only valid under highly restrictive assumptions. The uncertainty about the value of a solution once implemented in the total railway system therefore remains high and many innovation processes therefore end with the proof-of-concept. This studies’ contribution to existing theory is the provision of an alternate explanation for the rigidity of railway systems and network-based infrastructures in general. Rather than incremental innovations as a result of political decision making in a network of interdependent actors with conflicting incentives, incremental innovations can also be a result of a more sequential and phased decision making processes as project managers purposefully decrease the technical and social complexity beforehand.","decision making; process innovation; railway systems","en","conference paper","","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

Meanwhile there is a push for quality improvements leading to more robustness and resilience as well as a significant capacity increase. In the years 2009 - 2010, the gaming group of Delft University of Technology was asked to introduce gaming simulation methodology at ProRail, the Netherlands’ rail infrastructure manager, to support innovation projects. Three initial trial projects ran so successful that the organization asked the Delft researchers to identify where in the organization large-scale implementation of gaming simulation methodology would be most promising. Based upon a series of interviews through the organization, ProRail and TU Delft jointly formulated a four-year research and implementation proposal that is now in operation. The first gaming session in this new collaboration proved the essence of the fit of gaming simulation for innovation at the Dutch railways. Unique for gaming simulation is the highly detailed simulation of both the more technical and process variables of rail infrastructures as the decision and communication function of real people in their real roles. The method does not assume models of decision-making but draws upon the real-world knowledge of professionals in the operation. The paper gives lessons learned on methodological challenges resulting from the four projects described.","gaming simulation; innovation; railway operation; infrastructure management","en","journal article","Elsevier","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

This was a part of the project as a whole, about which you will also read. A separate publication was made for each individual Livinggreen Lab. This overall publication pulls these results together, providing an overview of the methodology as was developed and tested with these labs. By considering the full results it is easier to recognise the flexibility that needs to be allowed when considering to use this ‘Livinggreen Lab’ method in the future. The five themes in the project were Energy, Water, Eco-Materials, Architectonic values and Climate Resilience. On all topics the project team from Delft University of Technology (DUT) worked together with another partner. These were respectively: City of Ludwigsburg (Germany), EcoHouse Antwerp (Belgium), National Trust (UK), City of Lille (France) and White Rose Foundation (The Netherlands). The diversity of themes and partners combined with the desire to develop a methodology that can be repeated was a formidable challenge, on which the DUT team has worked with a lot of energy. Each development, expected and less so, has contributed to our overall insights of the usability and relevance of the methodology “Livinggreen Labs”. Besides pulling the reports of each individual Lab together, we will share some of these insights with you in this document, and refer to deeper analyses in related papers that the team has produced.","","en","report","Delft University of Technology","","","","","","","","Industrial Design Engineering","Design Engineering","","","",""

inaccuracy better than ±0.1 °C over the military temperature range is obtained, which is in-line with the state-of-the-art. This performance is achieved at a power consumption of 65 μW during a measurement time of 100 ms, by optimizing the power/inaccuracy tradeoffs, and by employing a clock frequency
proportional to absolute temperature.

In the context of the complexity of cities, these challenges become wicked and ill-defined as e.g. socialeconomic issues are added. To face these challenges, a city’s resilience on multiple scales has to enable it to both mitigate the causes and adapt to the aforementioned effects. In resilience literature the concept of panarchy connects resilience of multiple scales in a system, e.g. a city, and shows a causal relationship between them: a system is only as resilient as it’s sub-systems. Much like a chain being as strong as its weakest link. Despite the panarchy-principle, the complexity of the city thwarts pointing out the effects increasing resilience in a sub-system may have on the scale of the city. In an era of disruptions so significant that we refer to them in a single-name shorthand (think: 9/11, Katrina, Fukushima, Haiti, Sandy) what gives cities their ability to bounce back? In this study we focus on the social systems in cities, and specifically on grassroots initiatives. The number of grassroots initiatives (GRI’s) has increased tremendously over the last 10 years. Two major groups can be identified: those instigated by an immediate cause, e.g. in the wake of disasters like hurricane Katrina or Sandy, and those dealing with long term goals, such as those that are sustainability driven like the Transition Town movement. The latter GRI’s actively shape cities through themes like food growing, insulation of residential buildings , local energy generation, and civil participation. GRIs operate on the lowest organisational level in cities and form a loose, but potentially large system within the city. The hypothesis of this study is that despite the complexity of cities, GRIs contribute significantly to the social resilience of cities. To investigate this effect, a good understanding of their role in cities is necessary. This paper reviews relevant literature and combines them with observations to formulate a framework, within which GRIs can be placed. To test this framework, a first case study is done. Additionally, directions for further research will be discussed.","","en","conference paper","Delft University of Technology","","","","","","","","Industrial Design Engineering","Design Engineering","","","",""

Other market parties are expected to step in. This has consequences for the requirements that are set for the overall usability and energy performance and resource use, of heritage buildings. Currently, the commonly used way of value assessment of listed heritage buildings is not equipped to deal with the new demands. It is restrictive in the changes that are allowed to be made, inhibiting the changes necessary to accommodate new demands on 1) usability, and 2) sustainability. These add to two general issues with the currently used value assessment. Firstly, the method with which value assessments are made it hardly takes immaterial values into account. Secondly, the method and its resulting assessment is difficult for designers to use: it lacks handholds on the values that aid design decisions. In the present study, we suggest limitations of the conventional value assessment method. Instead of only charting the (cultural) historic importance of the material, we focus on the perception of this cultural historic value: the feeling of history that is evoked by the material. Using theory on ‘sense of place’ from the fields of urban and landscape planning and geography, a model for the ‘sense of history’ is proposed, for which the sensory experience is taken as a starting point. This has led to five elements of space that describe the way it is experienced: (1) spatial qualities, (2) material finishes, (3) indoor climate, (4) traces of use and (5) craftwork. The method presents these values in such a way that they can be used directly in the design and decision process, by architect, user and sustainability expert.","","en","conference paper","Delft University of Technology","","","","","","","","Industrial Design Engineering","Design Engineering","","","",""

Less than 1% of the total building stock in North-West Europe is renewed each year, which means that most gain has to be achieved by renovation of the existing building stock in combination with changes in behaviour by residents, the end-users of the buildings. Commonly used methods to stimulate and support residents in making adjustments to their homes, are mostly monodirectional. Residents then are passive receivers of information and advice. Previous research shows that active involvement and multidirectional exchange leads to better results. In line with these findings, the study presented in this paper takes approaches that are used in the field of product development for and with end-users as a starting point. These approaches, such as co-design processes, creativity techniques and vision development to come to novel ideas, appear to have characteristics that are conducive to stimulate people to make changes towards sustainable renovation. The study explored if and in what way these approaches can complement the commonly applied methods. For this purpose, a number of sessions, called 'Livinggreen Labs', were organised. In the sessions several techniques were applied for a number of themes and with varying types of participants. The sessions were evaluated by the participants, as well as by the organisers. The findings suggest that the approach tested in this study can provide an attractive complementary way to sensitise people to the possibilities of sustainable renovation and sustainable lifestyles. The sessions showed high involvement of the participants. Peerlearning and exchanging perspectives between people with different backgrounds were highly appreciated. The approach seemed to be most useful for vision forming and participatory processes in local urban development programs as opposed to best practice knowledge transfer. In order to more purposefully compare these different methods in the future, the former might be called “emerging knowledge transfer”. Because of the specific context of the project in which the study is executed, further investigation is required to assess whether and how the results apply in different contexts. Furthermore, detailed insight is to be developed in what ways the use of techniques from the design field, together with existing methods, yield the best longterm effects on sustainable renovation activities by residents, i.e., achieve real impact.","","en","conference paper","Delft University of Technology","","","","","","","","Industrial Design Engineering","Design Engineering","","","",""

The possibilities and pitfalls of using System Dynamics for policy analysis in the Dutch rail system have been explored by performing a modelling study into the interrelations of modal split, mobility and operations using System Dynamics. Additional scrutiny is placed on the method, because of the unstructuredness of many problems in the rail sector, and decision-making in a network type environment. Results show that the reliability of infrastructure is a major component in the extent of delays. Furthermore, the effect of unreliability in a train trip and the characteristics of a car trip are important for the choice between train and car. Although classical policy analysis has proven to be possible, modelling the operational part of the system has proven challenging due to the spatial and discrete characteristics of parts of the system. Recommendations are given to improve the model and model use to better suit the unstructuredness of the problems.","rail system; Netherlands; policy analysis; system dynamics","en","conference paper","System Dynamics Society","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

Hence, we investigated the processes governing P transport in a 28 km2 slum-dominated catchment in Kampala, Uganda. During high runoff events and a period of base flow, we collected hourly water samples (over 24 h) from a primary channel draining the catchment and from a small size tertiary channel draining one of the contributing slum areas (0.5 km2). Samples were analyzed for orthophosphate (PO4-P), particulate P (PP), total P (TP) and selected hydro-chemical parameters. Channel bed and suspended sediments were collected to determine their sorption potential, geo-available metals and dominant P forms. We found that P inputs in the catchment originated mainly from domestic wastewater as evidenced by high concentrations of Cl (36–144 mg L-1), HCO3 and other cations in the channels. Most P discharged during low flow conditions was particulate implying that much of it was retained in bed sediments. Retained P was mostly bound to Ca and Fe/Al oxides. Hence, we inferred that mineral precipitation and adsorption to Ca-minerals were the dominant P retention processes. Bed sediments were P-saturated and showed a tendency to release P to discharging waters. P released was likely due to Ca-bound P because of the strong correlation between Ca and total P in sediments (r2 = 0.9). High flows exhibited a strong flush of PP and SS implying that part of P retained was frequently flushed out of the catchment by surface erosion and resuspension of bed sediment.

If there is too much tension in the suture, the blood flow is restricted and necrosis can occur. If the tension is too low, the incision opens up and cannot heal properly. The purpose of this paper is to describe the design and evaluation of the Stitch Force (SF) sensor and the Hook-In Force (HIF) sensor. These sensors were developed to measure the force on a tensioned suture inside a closed incision and to measure the pulling force used to close the incision. The accuracy of both sensors is high enough to determine the relation between the force in the thread of a stitch and the pulling force applied on the suture by the physician. In a pilot study, a continuous suture of 7 stitches was applied on the fascia of the abdominal wall of multiple pigs to study this relationship. The results show that the max force in the thread of the second stitch drops from 3 (SD 1.2) to 1 (SD 0.3) newton after the 4(th) stitch was placed. During placement of the 5(th), 6(th) and 7(th) stitch, the force in the 2(nd) stitch was not influenced anymore. This study indicates that in a continuous suture the force in the thread remains constant up to more than 3 stiches away from the pulled loose end of the suture. When a force feedback tool is developed specially for suturing in surgery on patients, the proposed sensors can be used to determine safety threshold for different types of tissue and sutures.","","en","journal article","Public Library of Science","","","","","","","","Mechanical, Maritime and Materials Engineering","Biomechanical Engineering","","","",""

This is primarily due to large inputs of untreated wastewater to urban drainage channels, especially in informal settlements (or slums). However, the processes governing the fate of P in these catchments are largely unknown. In this study, these processes are investigated. During high runoff events and a period of base flow, we collected hourly water samples (over 24 h) from a primary channel draining a 28 km2 slum-dominated catchment in Kampala, Uganda, and from a tertiary channel draining one of the contributing slum areas (0.54 km2). The samples were analysed for orthophosphate (PO4-P), particulate P (PP), total P (TP), suspended solids (SS) and hydrochemistry. We also collected channel bed and suspended sediments to determine their geo-available metals, sorption characteristics and the dominant phosphorus forms. Our results showed that the catchment exported high fluxes of P (0.3 kg km2 d?1 for PO4-P and 0.95 for TP), which were several orders of magnitude higher than values normally reported in literature. A large proportion of P exported was particulate (56%of TP) and we inferred that most of it was retained along the channel bed. The retained sediment P was predominantly inorganic (>63% of total sediment P) and consisted of mostly Ca and Fe-bound P, which were present in almost equal proportions. Ca-bound sediment P was attributed to the adsorption of P to calcite because surface water was near saturation with respect to calcite in all the events sampled. Fe-bound sediment P was attributed to the adsorption of P to iron oxides in suspended sediment during runoff events given that surface water was undersaturated with respect to iron phosphates. We also found that the bed sediments were P-saturated and showed a tendency to release P by mineralisation and desorption. During rain events, there was a flushing of PP which we attributed to the resuspension of P-rich bed sediment that accumulated in the channel during low flows. However, firstflush effects were not observed. Our findings provide useful insights into the processes governing the fate and transport of P in urban slum catchments in SSA.","","en","journal article","European Geosciences Union","","","","","","","","Civil Engineering and Geosciences","Water Management","","","",""

Samples were analyzed for orthophosphate (PO4?P), particulate P (PP), total P (TP) and selected hydro-chemical parameters. Channel bed and suspended sediments were collected to determine their sorption potential, geo-available metals and dominant P forms. We found that P inputs in the catchment originated mainly from domestic wastewater as evidenced by high concentrations of Cl (36–144mgL?1), HCO3 and other cations in the channels. Most P discharged during low flow conditions was particulate implying that much of it was retained in bed sediments. Retained P was mostly bound to Ca and Fe/Al oxides. Hence, we inferred that mineral precipitation and adsorption to Ca-minerals were the dominant P retention processes. Bed sediments were P-saturated and showed a tendency to release P to discharging waters. P released was likely due to Ca-bound P because of the strong correlation between Ca and total P in sediments (r 2 = 0.9). High flows exhibited a strong flush of PP and SS implying that part of P retained was frequently flushed out of the catchment by surface erosion and resuspension of bed sediment. Our findings suggest that P accumulated in the channel bed during low flows and then was slowly released into surface water.

However, the publication of open data is often cumbersome and there are no standard procedures and processes for opening data. This blocks the easy publication of government data. The purpose of this paper is to derive design principles for improving the open data publishing process of public organizations. · Design/methodology/approach: Action Design Research (ADR) was employed to derive design principles. The literature was used as a foundation, and discussion sessions with civil servants were used to evaluate the usefulness of the principles. · Findings: Barriers preventing easy and low-cost publication of open data were identified and connected to design principles, which can be used to guide the design of an open data publishing process. Five new principles are 1) start thinking about the opening of data at the beginning of the process, 2) develop guidelines, especially about privacy and policy sensitivity of data, 3) provide decision support by integrating insight in the activities of other actors involved in the publishing process, 4) make data publication an integral, well-defined and standardized part of daily procedures and routines, 5) monitor how the published data are reused. · Research limitations/implications: The principles are derived using ADR in a single case. A next step can be to investigate multiple comparative case studies and detail the principles further. We recommend using these principles to develop a reference architecture. · Practical implications: The design principles can be used by public organizations to improve their open data publishing processes. The design principles are derived from practice and discussed with practitioners. The discussions showed that the principles could improve the publication process. · Social implications: Decreasing the barriers for publishing open government data could result in the publication of more open data. These open data can then be used and stimulate various public values, such as transparency, accountability, innovation, economic growth and informed decision and policy-making. · Originality/value: Publishing data by public organizations is a complex and ill-understood activity. The lack of suitable business processes and the unclear division of responsibilities blocks publication of open data.

The energy saving potential of the building stock is large and considered to be the most cost efficient sector to contribute to the CO2 reduction ambitions. Goals set by the European Union are to build net zero energy buildings in 2020 and to reach a neutral energy building stock by 2050. As long as the price of renewable energy is still not competitive with fossil energy, the energy saving goals can only be reached by strict governmental policies. In Europe the Energy Performance of Buildings Directive and the Energy Efficiency Directive are driving forces for EU Member States to develop and strengthen energy performance regulations for new buildings and energy performance certificates (labels) for the building stock. The goal of this paper is to analyse the consequences of these developments on the systems of building regulations and control. It appears that, apart from adding new subjects, these new and very ambitious goals require systemic innovations in the regulatory systems. The current structures and approaches might not be adequate to deal with the new challenges.

We show how our developed GeneTiles software can improve RNAseq analysis approaches by more confidently identifying a large set of markers upon infection with these bacteria. For analysis of RNAseq data currently, software programs such as Bowtie2 and Samtools are indispensable. However, these programs that are designed for a LINUX environment require some dedicated programming skills and have no options for visualisation of the resulting mapped sequence reads. Especially with large data sets, this makes the analysis time consuming and difficult for non-expert users. We have applied the GeneTiles software to the analysis of previously published and newly obtained RNAseq datasets of our zebrafish infection model, and we have shown the applicability of this approach also to published RNAseq datasets of other organisms by comparing our data with a published mammalian infection study. In addition, we have implemented the DEXSeq module in the GeneTiles software to identify genes, such as glucagon A, that are differentially spliced under infection conditions. In the analysis of our RNAseq data, this has led to the possibility to improve the size of data sets that could be efficiently compared without using problem-dedicated programs, leading to a quick identification of marker sets. Therefore, this approach will also be highly useful for transcriptome analyses of other organisms for which well-characterised genomes are available.","RNA deep sequencing; host pathogen interaction; zebrafish; staphylococcus epidermidis; mycobacterium marinum; differential splicing","en","journal article","Springer","","","","","","","","Electrical Engineering, Mathematics and Computer Science","Software Computer Technology","","","",""

The scale and extent of the connections have complex impacts on, and are impacted by, both the demand for and supply of labour and the socio-ecological transition. The ageing of European populations, for example, will continue to influence the demand for housing in terms of location, size and services, which in turn will create jobs in construction, raw material acquisition and delivery, infrastructure (ranging from roads to medical services) and transaction activities (such as legal services, new furniture and fittings). The link between the geographical location of the family residence and of the workplace will be altered by further developments of ICT and home working, influencing the impact of housing sectors on the direct supply of labour. Of the many possible linkages and considerations for policy-makers in relation to the housing sector, this chapter focuses on three specific aspects.

The aim of this study was to examine individual markers of resilience and obtain quantitative insights into the understanding and the implications of variation and expertise levels in train traffic operators’ goals and strategic mental models and their impact on performance.
Background:
The Dutch railways are one of the world’s most heavy utilized railway networks and have been identified to be weak in system and organizational resilience.
Method:
Twenty-two train traffic controllers enacted two scenarios in a human-in-the-loop simulator. Their experience, goals, strategic mental models, and performance were assessed through questionnaires and simulator logs. Goals were operationalized through performance indicators and strategic mental models through train completion strategies.
Results:
A variation was found between operators for both self-reported primary performance indicators and completion strategies. Further, the primary goal of only 14% of the operators reflected the primary organizational goal (i.e., arrival punctuality). An incongruence was also found between train traffic controllers’ self-reported performance indicators and objective performance in a more disrupted condition. The level of experience tends to affect performance differently.
Conclusion:
There is a gap between primary organizational goals and preferred individual goals. Further, the relative strong diversity in primary operator goals and strategic mental models indicates weak resilience at the individual level.
Application:
With recent and upcoming large-scale changes throughout the sociotechnical space of the railway infrastructure organization, the findings are useful to facilitate future railway traffic control and the development of a resilient system.","goal competition; diversity; organizational resilience; railway; sociotechnical system","en","journal article","","","","","","","","","","","Organisation & Governance","","",""

Aim. In this article, we aim to investigate the validity of the gaming simulations for training traffic controllers for new situations in rail infrastructure. We also aim to contribute to the discussion on the minimum level of fidelity required to develop and conduct gaming simulations in a valid way. Method. We investigate the validity by using training sessions in conjunction with questionnaires. We based the approach and questionnaires on the earlier work of Raser. Results. Our results show that the validity of the gaming simulation ranges from medium to good. They also show that while the fidelity of the gaming simulation is not like the real-world operating conditions, this does not reduce validity to low levels. Conclusions.

Debriefing is an intrinsic part of games for learning and proper
debriefing can also be beneficial to research games. However, the literature
on how to debrief research games is sparse and only provides the professional
with an abstract topic guide.
Aim. The purpose of this study was to design a framework for the debriefing of
research games that are used in ongoing innovation processes.
Method. We used the literature on debriefing and experimental research and our
experience as game designers to build a framework that tackles the context,
substance and method of debriefing research games.
Results. Our framework provides three contributions. First, it shows how
the context in which a research game is applied sometimes impacts the
functionality of the game in negative ways. This can be helped by designing both
the game and the debriefing together. Second, we operationalize validity to a
greater extent, as this is the core of a good research game. Third, we provide
a methodology for debriefing professionals that opens up the black box of the
gaming simulation session.
Conclusion. The debriefing framework provides a method to collectively assess
the validity, reliability and robustness of the causal claims associated with the
research conducted.","","en","journal article","","","","","","","","","","","Organisation & Governance","","",""

The influence of EU policy goals and contents of EU Directives reverberate strongly in the energy regulations. Goals set by the European Union are that all newly built constructions must have a zero energy level by 2020 and that the total building stock must be energy neutral by 2050. The Energy Performance of Buildings Directive and the Energy Efficiency Directive are designed to give Member States the regulatory tools to develop and strengthen energy performance regulations. There are indications that the current (energy) regulations alone are inadequate to realize the energy saving goals set by the EU and its Member States. The goals can only be reached by more strict and supportive governmental regulations. That does not only mean formulating more stringent demands. It also poses new challenges to the way the construction process is organized and the regulations are enforced and the roles and responsibilities of constructors (building and installation companies). In the quality control procedures focus should be put on the quality of the building as it is built and preferably as it is going to be used. The question is if current quality control frameworks are organized adequately in European countries to meet these demands. To give a beginning of an answer to this question we look at the regulatory systems of seven European countries (England & Wales, Ireland, Germany, France, the Netherlands, Norway, and Sweden) where private building professionals already play a dominant role in the quality control process. The paper zooms in on the robustness and focus of the quality control process and the demands that are made on building and installation companies with respect to meeting the quality demands. It appears that current building regulatory systems are not yet geared completely with the future demands.","building regulations; quality control; European Union; housing quality","en","conference paper","Tampere University of Technology","","","","","","","","","","OLD Housing Quality and Process Innovation","","",""

In most European countries local authority building control were responsible for the issuing of planning or building permits and carried out plan approval, site-inspections and checks on completion of constructions. During the last decades however these building control tasks have been outsourced more and more to private parties. The main driving force behind this development has been the wish of governments to deregulate. The shift of responsibilities to the private/market parties should not only improve the quality of construction works but it could also streamline administrative procedures and processes. In the eyes of the policymakers this leads to a win-win situation: less regulation, leading to a qualitative better building stock through optimised (cheaper & faster) quality control procedures. It is exactly because of these reasons that the Dutch government is on the brink changing its quality control system of constructions towards a more private model.

The abstraction from the real world as needed for applying clear planning tools has grown to considerably differ from the complex urban fabric of activities underlying the transport demand, such as food distribution, commercial activities, education networks, health, etc, especially in busy metropolitan areas. Inclusion of new parameters and use cases in design poses new methodological challenges. The socio-cultural context of urban areas provides for meaningful explanations for the use of urban infrastructure. The cultural context determines the expectations placed on the infrastructure by the people. For example, accessibility for the elderly and children, security and availability. Rapid urbanisation and increased economic inequality in cities has provided additional parameters to understand the longevity and contribution of transport infrastructure. The use of new methods such as the availability of real time data, sensor based data and additional social network analytical methods can provide new insights to understand the needs of the urban masses. Transport infrastructure needs to cater to local needs and become part of a larger ecosystem of a city.

Theoretical energy saving predictions are an important and frequently used tool for policy makers to develop energy saving policies and to set energy saving targets. Majcen et al.

The existence of the energy performance gap means that policy makers base their policies on assumptions that are not always right. It is expected that a significant part of the performance gap can be explained by the occupant behaviour, therefore a better insight in the influence of occupant behaviour on actual residential energy consumption is required. In this paper a method is introduced to analyse the influence of occupant behaviour on residential energy consumption, based on the principle that if occupant behaviour is studied also the building characteristics should be taken into account. In this paper a data analysis is executed with the use of a large building characteristics database (SHAERE - over 2 million cases), occupant data (Statistics Netherlands - entire Dutch population) and energy data (Statistics Netherlands – entire Dutch population). Although the results of the executed analysis are not conclusive, several important factors were found for further research. Firstly, the building and occupant cluster variables should be created with great care since they are one of the determining factors for correct function of the method. Secondly the quality of the dataset is of major importance for the final result. Finally, for further research it is advised to execute this method on other datasets, and compare the results in order to define which aspects are most important for applying this method.","Performance gap; Housing; Actual energy; Occupant characteristics; Method","en","conference paper","INESC Coimbra","","","","","","","","","","OLD Housing Quality and Process Innovation","","",""

Energy labelling calculations, as well as energy consumption forecasts, on which energy policies rely, are based on models. In the past years several studies have demonstrated that these models show large deviations from reality, making the prediction of possible energy sav-ings biased. These poor predictions can be hypothesised to be the result of poor estimation of the U–values of walls, poor estimation of the infiltration and ventilation flow rates and poor estimation of the heated surface area and of the temperature preferences of occupants. Additionally, there is very little knowledge on how occupant’s perception of comfort influences their ventilation and heating behaviour and finally the total energy use for heating.
This report presents the results of a field study in which monitoring data was collected in order to further analyse parameters that could influence strongly the heating energy consumption and to fi-nally improve energy prediction models.

(TU Delft OLD Housing Quality and Process Innovation)","","2017","Purpose: This paper aims to evaluate the quality control systems for constructions in seven countries in Europe with the purpose to trace innovative approaches and best practices that can serve as examples for other countries. Design/methodology/approach: The paper is based on a series of research projects carried out over a number of years. The research results were updated in 2016 with a desktop research project in seven European countries. The results from this latest project form the heart of this paper. The information is organised into tables that describe and analyse the main features of the quality control systems of the countries (e.g. scope, focus and main characteristics of the procedures and quality demands on building professionals). Findings: Several similar trends can be recognised in the quality control systems of the various European Union (EU) countries. Quality control is getting more and more privatised and the control framework is setting checks and balances throughout the construction process. Other findings are that scope and focus of the statutory control is unbalanced. Within the control processes emphasis is put on the safety aspects of complex constructions. Far fewer demands are made on the quality of the builders. Re-orientation of the building regulatory framework seems to be needed. Research limitations/implications: The paper only focusses on European countries where private quality control is established and on selected topics. The findings are based on desktop research and not on the practical experiences of the stakeholders involved in the countries studied. Practical implications: The paper draws some important recommendations for policymakers in the building regulatory field. It suggests both an enhancement of the effectiveness of the quality control procedure as well as the commitment of builders to comply with the regulations. Social implications: The quality of constructions is essential for the wellbeing and safety of its users, its occupants or its visitors. This applies to the whole range of quality aspects: structural- and fire safety, health, sustainability and usability aspects. The analyses and recommendations of this paper aim to contribute to an improvement of the overall construction quality. Originality/value: The paper makes an original contribution to the (limited) literature that is available in this field. The results can be used to situate the quality control systems of each member state within the EU, to assess the main trends, and it can be used as a guide to develop strategic choices on possible improvements in each country.","Building regulations; Construction quality; European Union; Privatisation; Quality control; Sustainability","en","journal article","","","","","","","","","","","OLD Housing Quality and Process Innovation","","",""

It employs substrate p-n-ps as sensing elements,which makes it insensitive
to the effects of mechanical (packaging) stress and facilitates the use of low-cost packaging technologies. The sensor outputs a duty-cycle-modulated signal, which can easily be interfaced to the digital world and, after low-pass filtering, to the analog world. In order to eliminate the errors caused by the component mismatch, chopping and dynamic element matching (DEM) techniques have been applied. The required component shuffling was done concurrently rather than sequentially, resulting in a fast DEM scheme that saves energy without degrading accuracy. After a singletemperature trim, the sensor’s inaccuracy is ±0.1 °C (−20 to 60 °C) and ±0.3 °C (−45 to 130 °C), respectively. Measurements of sensors in different packages show that the package-induced shift is less than 0.1 °C. Measurements of eight sensors over 367 days show that their output drift is less than 6 mK. While dissipating only 200 μW, the sensor achieves a resolution of 3 mK (rms) in a 1.8-ms measurement time, and a state-of-the-art resolution figure of merit of 3.2 pJK2. This combination of high accuracy, high resolution, high speed, and low-energy consumption makes this sensor suited for commercial and industrial applications.","one-point trim; Chopping; CMOS temperature sensor; duty-cycle modulation; dynamic element matching (DEM)","en","journal article","","","","","","Accepted author manuscript","","","","Microelectronics","Electronic Instrumentation","","",""

In 2017, the Belgian government decided to cover over 95% of the cost for all women who choose to take this test. In this context, a diagnosis of trisomy 21 (Down syndrome) presents an especially challenging decision for parents: it is impossible to tell the severity of impairment prenatally, and although several medical risks are involved in the condition, many individuals with Down syndrome live a long, happy, and relatively independent life (Shakespeare, 1998; Scott et. al., 2014). Expectant parents face a very difficult situation: how to decide whether or not to terminate a pregnancy? It appears that termination is becoming the routinized outcome of the clinical encounter during which a diagnosis is delivered.
The intricacy of the matter, and the fact that many actors are involved, lead to the necessity of a transdisciplinary methodology when scrutinizing the future of prenatal counseling. However, medical professionals tend to approach Down syndrome from an exclusively medical perspective (Skirton and Barr, 2010), leaving aside the economic, social and psychological dimensions of living with Down syndrome. This may result in unbalanced information; some (perhaps precipitously) refer to this phenomenon as ‘nudging practices’ (Hippman et. al., 2012; Reid et. al., 2009). In order to address this imbalance, we adopt a stakeholder approach in this project: we consulted experts with diverse backgrounds and fields of expertise. Through this transdisciplinary approach, we hope to bring about a more transdisciplinary perspective directly within the offices of gynecologists and GPs. More specifically, we aim to find ways to provide GPs and gynecologists with direct access to information about the aforementioned dimensions of Down syndrome.
The next step is to define a strategy to achieve this goal. Given the fact that medical professionals often lack both time and easy access to concise information about Down syndrome to present a nuanced perspective (Ahmed et. al., 2007), but are still the first in the prenatal screening process, the output of this project is the idea of an online tool in a succinct Q&A format. The goal of such a website would be to provide up-to-date, easily accessible and balanced information for general practitioners and gynecologists on multiple aspects of Down syndrome. This way, in anticipation of and directing explicitly towards further counseling by a multidisciplinary team, physicians can provide expectant parents with a more balanced, transdisciplinary view of Down syndrome, thereby enhancing their capability to make informed, autonomous and hence sustainable decisions about their pregnancies.","non-invasive testing; informed decision making; Prenatal screening; Down syndrome; non-directive counseling","en","journal article","","","","","","","","","","","","","",""

As opposed to conventional methods, the proposed method does not rely on iterative hydraulic calculations; instead, the structure of the network is taken as a starting point. In contrast to methods applied in practise, the results are independent on the chosen test-load. Because of the limited calculation effort, the method allows the analysis of large networks that are now, for practical reasons, beyond the scope of methods applied so-far.","1D-networks; Asset management; Critical sewers; Graph-theory; Sewer systems; OA-Fund TU Delft","en","journal article","","","","","","","","","","","Sanitary Engineering","","",""

As can be seen from the discussions on blockchain applications, both practitioners and researchers struggle to get to the core of blockchain technology consequences. Especially practitioners in the governmental sector explore adequate responses to this new technology. Therefore, our aim is to provide a conceptualization of the consequences of blockchain systems from an institutional perspective, and to use this conceptualization to provide insights into the governance of blockchain systems. We use a Grounded Theory approach to conceptualize the institutional consequences of blockchain technology. This approach leads to our core category: power transfer in environments with highly institutionalized values. This core category supports the synthetization of the governance issues related to blockchain systems. We conclude that the controlling powers that were formerly vested in highly institutionalized organizations (such as governments and regulators) and institutions (such as legal frameworks and agreements), are no longer automatically part of the governing ecosystem in blockchain systems but are engrained into the technical system itself. Thus, Blockchain technology enables the technological institutionalization of values in environments that are highly dependent on these values. We believe that this is at the core of why existing institutions are being pressured by blockchain technology, and as such increase the difficulty for governments to effectively govern blockchain systems. Using this notion, public and private parties within the blockchain ecosystems can develop regulatory arrangements and strategies that strike a balance between fostering the innovative power and possibilities that blockchain applications offer and to mitigate possible negative effects of blockchain technology.","Blockchain technology; Control; Governance; Institutions; Trust","en","conference paper","Association for Computing Machinery (ACM)","","","","","Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2018-12-01","","","Information and Communication Technology","","",""

The geometric model of unknown object is constructed by using a single-view partial point cloud. To examine the algorithm using simulations, a comparison of the commonly used motion planners is made. The motion planner with the highest number of solved runs, lowest computing time and the shortest path length is chosen to execute grasps found by this grasping algorithm. The simulation results demonstrate that excellent grasping efficiency is achieved by adopting our algorithm. To validate this algorithm, experiment tests are carried out using a UR5 robot arm and an under-actuated gripper. The experimental results show that steady grasping actions are obtained.

Based on 12 pitfalls identified in literature, and through the use of an online questionnaire, facilitation experts evaluated the extent to which these pitfalls occur due to the design or the execution of the debriefing, and the extent to which they are influenced by the rules of games and simulations. All 12 pitfalls seem to occur in practice, to some extent, due to both the design and the execution of the debriefing. Nevertheless, some pitfalls appear to be more influenced either by design or by execution. Moreover, the results on the extent to which the pitfalls are influenced by the rules of games and simulations are inconclusive, due to the contradiction between the answers on the pre-defined questions and the comments of the experts.

This report looks into opportunities for stimulating homeowners to adopt energy-saving technologies by improving municipal communication channels, particularly web portals.
First, literature research reflects on the influence of communication channels on homeowner renovation decision-making processes. The research further provides an inventory of strengths and weaknesses of existing web portals aimed at awareness raising among homeowners and reflects on new web platform developments.
Secondly, data on current web portals of local authorities were collected from local authorities in four countries (Belgium, France, The Netherlands, UK). The qualitative analysis compares existing local authorities’ web portals against key characteristics for providing homeowner support, to identify potential for improvement.
Thirdly, local scoping workshops were organized in seven local authorities to determine most effective modules to improve local authority web portals. A demo workshop resulted in a list of desired web functions for local authorities. Local discussion with stakeholders revealed the main opportunities and barriers for improving existing local authority web portals and a selection of at least five web functions for immediate development.
The research resulted in a long-term perspective on web portal development and a set of modules and recommendations for strengthening local authorities’ web portals for increasing awareness and easy access to low carbon technologies. Based on this, seven local authorities identified the most effective modules to improve their web portals in the short term in co-creation with stakeholders.","","en","report","Interreg","","","","","Project No. 2S02-029","","","","","Housing Management","","",""

This report analyses the experiences and opportunities that various models of consultancy centres and pop-up models can offer to stimulate homeowners to adopt energy-saving technologies.
In the first place experiences of already existing consultancy centres and pop-ups in the four countries of the Triple-A partners were analysed (Belgium, France, The Netherlands, UK). The customer journey model (e.g. the process starting with creating awareness, providing information up to the execution of energy saving measures) was used as the framework to reflect on the needed activities in centres and related pop-ups. The various examples are described in a short, concise format and were chosen because they illustrate the wide range of possible pop-up concepts.
Secondly the specific needs and wishes of the Triple-A partners were assessed. Via a questionnaire the partners were asked how they intended to use consultation centres and pop-ups (e.g. what kind of information do they want to provide in what way, to what target group?) and what kind of model they had in mind (e.g. a more permanent centre or a temporary pop-up?). Workshops were organised (held in Antwerp on the 13th October 2017) with the LA’s to determine and specify their wishes on business model development not only to determine possible pop-up model concepts but also to address public-private cooperation in this field. As a further illustration and as sources of possible inspiration the business models of a few selected existing consultation centres were reviewed in depth (Woon+bus, Kyotomobiel and EcoHuis in Belgium and Reimarkt and ICDuBo in the Netherlands). These few selected case were chosen because they fitted in within the Triple-A business models that have been formulated at the beginning of the project.","","en","report","Interreg","","","","","Project No. 2S02-029","","","","","OLD Housing Quality and Process Innovation","","",""

Report on impact of HEMS","Meijer, F.M. (TU Delft OLD Housing Quality and Process Innovation); Straub, A. (TU Delft OLD Housing Quality and Process Innovation); Mlecnik, E. (TU Delft Housing Management)","","2018","This report answers the question: How can HEMS be used to influence energy-saving behaviour of homeowners? Lessons regarding the feedback from HEMS to influence energy-saving behaviour have been explored and specifications of HEMS to influence energy saving by households are given.
Generally, the implementation of the Triple-A HEMS should appeal to (1) end-users (households) and (2) local authorities. Triple-A partners will provide HEMS to households to encourage them to change their energy behaviour and to trigger interest in the adoption of low carbon technologies. Another goal is to apply HEMS in demonstration exemplars (WP 4) to monitor the energy consumption of households and analyse consumption data before and after applying low carbon technologies.
HEMS with real time feedback have a good potential to influence the energy use and subsequent savings of households. In order to realise a structural change of the energy use behaviour it also must become customary for households to use the feedback system. The need of forming an energy saving habit also sets demands on the functionality and design of the feedback system. It must meet the preferences, capabilities and interest of a heterogonous group of homeowners or should be designed for specific customer segments. Direct feedback instruments primarily influence low-cost-quick-win measures: simple changes in behaviour that require little or no effort or investments. These behavioural changes however can potentially lead to substantial immediate savings.
The rollout of smart meters and HEMS differs strongly between the EU countries and the Triple-A countries. Energy providers can play an important role in the rollout of HEMS. The use of smart meters and HEMS and providing easy access of HEMS to homeowners could be one of the instruments of local energy saving programs and community-based reinforcement strategies of local authorities. A neighbourhood approach aims to enable more positive outcomes for energy savings and uptake of renovation measures, by using peer-to-peer communication, personal advice, trialling in demo houses and demonstration in pop-up centres and on local authority websites.
To monitor actual CO2 savings by local authorities within the demonstration areas, baseline requirements for HEMS deal with recording (or accessing data related to) annual energy use gas and/or electricity within the properties for a period of 12 months before and after installation. Next to baseline requirements local authorities can choose discretionary functions and requirements of HEMS, including e.g. measuring grid energy monitoring and comfort performance.
HEMS will also be used to give real-time feedback of the energy use to homeowners helping them to manage their energy consumption. For this purpose recommendations are:
• HEMS should be easy to use and accessible, and fit for purpose.
• Feedback should be real-time, frequent feedback enables the user to link behaviour to consequences.
• The specifications of the HEMS should match with the household characteristics and the willingness to use HEMS. A distinction between user groups is advisable: some users explicitly have more interest in more functionalities (and thus a more complex HEMS, others want a more intuitive user interface.
• Whether adoption of HEMS leads to the adoption of renovation measures is not (yet) known.
• HEMS should appeal to certain conditions of the homeowner (segments) or to solving issues within the home.
Overall recommendations for choosing HEMS include:
• The HEMS should be cost-effective.
• The installation of the HEMS should be easy (preferentially without electricity connection).
• The intrusion time for installing in the home should be minimized.
• A preference is given for HEMS that local authorities can experiment with free-of-charge to avoid de minimis statements.
• HEMS choice by local authorities will be influenced by the need to follow up KPI’s for energy saving, and thus by the compatibility with their own energy management system for analysing building stocks.","Home energy management systems; Energy Monitoring System; renovation; Local authorities; energy saving","en","report","Interreg","","","","","Project No. 2S02-029","","","","","OLD Housing Quality and Process Innovation","","",""

While hunger suppresses the fear circuitry to promote explorative food-seeking behavior, satiety or obesity may increase fear to prevent unnecessary risk-taking. Here we aimed to unravel which metabolic factors, that transfer information about the acute and the chronic metabolic status, are of primary importance to regulate fear, and to identify their sites of action within fear-related brain regions. We performed a de novo analysis of central and peripheral metabolic factors that can penetrate the blood-brain barrier using genome-wide expression data across the mouse brain from the Allen Brain Atlas (ABA). The central fear circuitry, as defined by subnuclei of the amygdala, the afferent hippocampus, the medial prefrontal cortex and the efferent periaqueductal gray, was enriched with metabolic receptors. Some of their corresponding ligands were known to modulate fear (e.g., estrogen and thyroid hormones) while others had not been associated with fear before (e.g., glucagon, ACTH). Additionally, several of these enriched metabolic receptors were coexpressed with well-described fear-modulating genes (Crh, Crhr1, or Crhr2). Co-expression analysis of monoamine markers and metabolic receptors suggested that monoaminergic nuclei have differential sensitivity to metabolic alterations. Serotonergic neurons expressed a large number of metabolic receptors (e.g., estrogen receptors, fatty acid receptors), suggesting a wide responsivity to metabolic changes. The noradrenergic system seemed to be specifically sensitive to hypocretin/orexin modulation. Taken together, we identified a number of novel metabolic factors (glucagon, ACTH) that have the potential to modulate the fear response. We additionally propose novel cerebral targets for metabolic factors (e.g., thyroid hormones) that modulate fear, but of which the sites of action are (largely) unknown.","Anxiety; Energy balance; Fear; Fear circuitry; Feeding; Metabolism; Monoamines; Obesity","en","journal article","","","","","","","","","","","Pattern Recognition and Bioinformatics","","",""

The abstraction of complex systems, which is required by default when modelling gaming simulations, is a convoluted and time-consuming process. For gaming simulations to be efficient and effective, the problem of the real system they imitate needs to be narrowed down and simplified as much as possible. Additionally, even after abstraction of the real system, multiple design decisions need to be made and these may differ depending on the gaming simulation. Aim. This article proposes a framework for formalizing, and consequently standardizing, expediting and simplifying, the modelling of gaming simulations. Method. The proposed framework applies game concepts pertaining to game theory in the abstraction of the real system and the game design decisions. Results. Application of the framework in three case studies reveals several advantages of incorporating game theory into game design, such as formally defining the game design elements and identifying the worst-case scenarios in the real-systems, to name but two. Conclusions. Given the framework’s advantages in general, and the game design recommendations it offers in particular, it is safe to conclude that, for the cases presented in this article, the framework make positive contributions towards the development of gaming simulations.","complex adaptive systems; game theory; gaming simulations; serious games","en","journal article","","","","","","","","","","","Organisation & Governance","","",""

These advantages have increased the importance of renovating existing residential buildings in many countries. In China, the government has supported the energy-saving renovation of existing urban residential buildings since 2007. However, quality failures, which do not meet the technical requirements, occur during construction processes in building energy renovation projects. Although quality failures are regarded as a crucial problem in building energy renovation projects, the identification of quality failures and their sources, likelihood, impacts, and causes remain mostly unknown. This paper investigates the nature of quality failures in building energy renovation projects. A total of 25 quality failures were first identified through five cases, and interviews with six experienced construction professionals in China. A questionnaire survey was further conducted to evaluate the frequency of quality failures. The results show the nature of quality failures that arise during construction and their sources, occurrence frequency, causes, and impacts. The research reveals that quality failures are caused by defaults by workers; inadequate checking procedures; incomplete construction site surveys; inaccurate design work; fraud of construction companies; and inefficient cooperation between different departments. Above all, the behaviors of the main actors are responsible for poor construction quality. Additionally, emphasis on quality control during the renovation preparation stage is critical to ensure that quality failures are reduced in numbers and severity.","Quality failures; building energy renovation projects; Northern China","en","journal article","","","","","","","","","","","Housing Quality and Process Innovation","","",""

(TU Delft OLD Housing Quality and Process Innovation)","","2019","Energy renovations often result in lower energy savings than expected. Therefore, in this study we investigate nearly 90,000 renovated dwellings in the Netherlands with pre and post renovation data of actual and calculated energy consumption. One of the main additions of this paper, compared to previous studies on thermal renovation, is that it only takes dwellings into account with the same occupants before and after renovation, using a large longitudinal dataset. Overall this paper shows new insights towards the influence of the energy efficiency state of a building prior to energy renovation, the type of building, the number of occupants, the income level of the occupants and the occupancy time on the actual energy savings, the energy saving gap and on the probability of lower energy savings than expected. We also investigate if the influence is different per type of thermal renovation measure. Some of the findings are: it is impossible to conclude which single thermal renovation measure is the most effective because this is dependent on the energy efficiency of the building prior to the energy renovation, type of building, income level and occupancy; occupants with a high income save more energy than occupants with low income; dwellings with employed occupants benefit more from improved building installations than dwellings occupied by unemployed occupants; The prebound and rebound effects are only part of the explanations for lower than expected energy savings; Deep renovations result more often in lower than expected energy savings than single renovation measures but nevertheless they result in the highest average energy saving compared to other thermal renovation measures. The results could be used for more realistic expectations of the energy reduction achieved by thermal renovations, which is important for (amongst others) policy makers, clients and contractors who make use of energy performance contracting, home owners, landlords and (social) housing associations and as a starting point to improve the energy calculation method.","Dwellings; Energy saving gap; Longitudinal data; Occupant and building characteristics; Thermal renovations","en","journal article","","","","","","Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2019-04-23","","","OLD Housing Quality and Process Innovation","","",""

This research assesses and gives insights in the progress to this objective for over 2.0 million dwellings of over 250 Dutch non-profit housing associations in 2017 and 2018. The assessment consists of an analysis of applied renovation measures, changes of the stock like new construction and demolishing, and clarifying characteristics of housing associations. It is concluded that large urban housing associations with adequate financial positions drive the improvement of the average sectoral energy performance. The improvement happens for a large part within the existing stock, mostly with traditional improvements like improved heating installations and improved insulation. Innovative solutions like: photovoltaic solar systems, combined heat and power systems, biomass systems, heat pumps and external heating, are responsible for a relative small part of the improvement within renovations. New construction and demolishing are also responsible for a relative small part of the annual improvement, but there is potential to improve this.","","en","journal article","","","","","","","","","","","Housing Quality and Process Innovation","","",""

However, they often result in lower-than-expected energy savings. In this paper, we investigate some parameters that influence the probability on lower-than-expected energy savings. We do this by comparing actual pre- and post-renovation energy consumption of 90,000 houses in the Netherlands. The results of this study confirm that the effect of the parameters differ per renovation measure. For every renovation measure, the energy performance gap post renovation plays a significant role. This implies that the use of actual energy consumption data to determine the potential energy savings could therefore help to reduce the number of renovations resulting in lower-than-expected energy savings. Also, the energy efficiency state of the building pre-renovation plays an important role. One should take into account that renovations of energy inefficient buildings more frequently result in lower-than-expected energy savings than renovations of relatively energy efficient buildings. For the type of house we found that multifamily houses more often result in lower than expected savings when building installations are improved, while single-family houses renovations more frequently result in lower energy savings than expected when the building envelope insulation is improved. These insights can contribute to the decision making process whether or not to take a certain renovation measures, they can also help to manage expectations on housing stock level and individual building level.","","en","journal article","","","","","","","","","","","Housing Quality and Process Innovation","","",""

The data has been collected through a survey among 3,776 of the Dutch homeowners in 2012. Then, statistical and logistic regression analysis has been conducted to analyze the renovation decisions for two groups of homeowners: renovators and potential renovators. According to the results and the outcomes of this study: (1) For the renovators: (a) the main identified stages in getting help are in carrying out the renovation, determining the costs, and looking for the reliable professional/ contractor, (b) the main identified sources of information are at the maintenance/ installation companies, family/ friends, and via internet; (2) For the potential renovators: (a) the main identified help stages are in determining the costs, looking for a reliable professional and carrying out the renovation/ improvement, (b) the main identified sources of information are via the internet, by a maintenance/ installation companies, and family/ friends. The main difference among the renovators is for insulation/ installation. The most significant stage in getting help for insulation/installation is to find out the most efficient solutions.

However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration debate. In this paper, we apply this view, and a more political one, to the context of big data and offer a qualitative study. We question the impact of big data on decision-making, realizing that big data – including its new methods and functions – must inevitably encounter existing political and managerial institutions. By studying two illustrative cases of big data use processes, we explore how these two worlds meet. Specifically, we look at the interaction between data analysts and decision makers. In this we distinguish between a rational view and a political view, and between an information logic and a decision logic. We find that big data provides ample opportunities for both analysts and decision makers to do a better job, but this doesn't necessarily imply better decision-making, because big data also provides opportunities for actors to pursue their own interests. Big data enables both data analysts and decision makers to act as autonomous agents rather than as links in a functional chain. Therefore, big data's impact cannot be interpreted only in terms of its functional promise; it must also be acknowledged as a phenomenon set to impact our policymaking institutions, including their legitimacy.","","en","journal article","","","","","","","","","","","Organisation & Governance","","",""

In this work, we discuss suitable evaluation metrics for this specific classification task — most notably ‘specificity at sensitivity’ and ‘precision at recall’ — and the importance of using a validation setup that includes a realistic ratio of images with defects to images without defects, and a sufficiently large dataset. We also introduce ‘leave-two-inspections-out’ cross validation, designed to eliminate a data leakage bias that would otherwise cause an overestimation of classifier performance. We designed a convolutional neural network (CNN) and applied this validation methodology to automatically detect the twelve most common defect types in a dataset of over 2 million CCTV images. With this dataset and our validation methodology, our CNN outperforms the state-of-the-art. Classification performance was highest for intruding and defective connections and lowest for porous pipes. While the CNN is not capable of fully automated classification at sufficient performance levels, we determined that if we augment the human operator with the CNN, this may reduce the required human labor by up to 60.5%.","Automated classification; CCTV inspection; Classifier validation; Convolutional neural networks; Image processing; Sewer asset management","en","journal article","","","","","","Accepted Author Manuscript","","2021-05-03","","","Sanitary Engineering","","",""

However, the scale of that influence lacks empirical investigation. The aim of this study was to distinguish which part of the variance in actual residential heating consumption can be attributed to the occupants, and which part to the building itself. This was achieved by applying and extending a method suggested by Sonderegger in 1978, using updated and significantly improved data from two different countries: the Netherlands and Denmark. These data contain different types of heating supply systems (district heating and natural gas) and different housing forms (multi and single-family social housing, and private detached single-family houses). For the studied databases, the results indicate that approximately 50% of the variance in heating consumption between houses can be explained by differences related to occupants. The other 50% can be explained by the characteristics of the building itself and other physical parameters, which are often not taken into account in simulation models of heat transmission within buildings. Additional analyses indicate that the relative influence of occupants on heating consumption differs depending on the building characteristics of the dwelling. For example, the influence of occupants is larger when the building is more energy efficient. Based on the research results, it can be concluded that it is unrealistic to aim for a building simulation model that perfectly projects residential heating consumption for individual cases. However, creating building simulation models and occupant consumption profiles that accurately represent average residential heating consumption should be possible.","Actual energy consumption; Building energy simulation; Occupants; Residential building; Space heating","en","journal article","","","","","","Corrigendum: https://doi.org/10.1016/j.apenergy.2020.114714","","","","","OLD Housing Quality and Process Innovation","","",""

The results indicate that the critical causes of quality failures are working under high-cost and high-time pressure, adverse natural conditions, fraud of construction companies, incomplete construction site survey, poor checking procedures of supervisors, poor operational skilled workers, inadequate equipment performance, lack of experienced project managers, and incomplete building information in projects.

As hardly any paper is focused on civil servants' attitude change through games, the authors broaden their research to attitude change through games in general. Out of 483 documents, 19 reference papers were analyzed in detail. Eighty-one games were found, and more than 13 different theories were identified containing 30 different influencing factors, which were found mostly to be unrelated and context-dependent. The conceptual dispersion between studies indicates that the resulting overview of factors is a first step towards creating a uniform theory.

This leads to exact energy conservation and superior performance in terms of accuracy when compared to a traditional segregated formulation.

The data was collected from a survey of 3,776 homeowners in the Netherlands. The main identified TC barriers were found to be at the consideration, decision, and execution phases of the renovation decision-making process, and are: finding a reliable professional/contractor to do exterior renovations, determining costs for interior renovations, and finding ways to increase the energy efficiency of the house using energy-saving renovations. The main sources of information for householders are construction stores/Do It Yourself (DIY), installations and maintenance companies for exterior and energy efficiency renovations, while for interior renovations it is construction stores/DIY companies, Internet, and recommendations from family/friends.

The building sector consumes 40% of resources globally, produces 40% of global waste and 33% of all emissions. The transition towards a Circular Economy (CE) in the built environment is vital to achieve Sustainable Development Goals (SDGs) such as responsible consumption and production. The built environment can gradually be made circular by replacing the current 'linear' building components with circular ones during maintenance and renovation. However, there are many possible design alternatives for circular building components; knowledge on which variants perform best - from an environmental perspective - is lacking. Methods. In this article, we develop environmental design guidelines for circular building components. First, we synthesize design variants for an exemplary circular building component: the Circular Kitchen (CIK). Second, we compare the environmental performance of these variants and a 'business-as-usual' variant by applying a Material Flow Analysis (MFA) and Life Cycle Assessment (LCA). Finally, from the results, we derive design guidelines. Results. We synthesized four design variants: (1) a kitchen made from bio-based, biodegradable materials, (2) a kitchen made from re-used materials, (3) a kitchen which optimises lifespans and materials, and (4) a modular kitchen in which components (with varying lifespans) are re-used by the manufacturer. From the LCA and MFA, we derived 7 design guidelines, which include: consider building components as a composite of sub-components, parts and materials with different and multiple use-, and life-cycles; match the materialisation of each part with the expected life cycle (merely substituting for re-used or low-impact materials does not provide the most circular design); facilitate various loops (e.g., repair, re-use, recycling) simultaneously. Conclusions. The presented design guidelines can support industry in developing circular building components and, through implementation of these components, support the creation of a circular built environment.","","en","journal article","","","","","","","","","","","Housing Management","","",""

Numerous loess records have been reported across the Asian continent with ages varying from the Miocene to the Eocene and linked to various mechanisms including global cooling, Tibetan Plateau uplift and retreat of the inland proto-Paratethys Sea. Here, we study the Eocene terrestrial mudrocks of the Xining Basin in central China and use nonparametric end-member analysis of grain-size distributions to identify a loess-like dust component appearing in the record at 40 Ma. This is coeval with the onset of high-latitude orbital cycles and a shift to predominant steppe-desert vegetation as recognized by previous studies in the same record. Furthermore, we derive wind directions from eolian dune deposits which suggest northwesterly winds, similar to the modern-day winter monsoon which is driven by a high pressure system developing over Siberia. We propose that the observed shifts at 40 Ma reflect the onset of the Siberian High interacting with westerly derived moisture at obliquity timescales and promoting dust storms and aridification in central China. The timing suggests that the onset may have been triggered by increased continentality due to the retreating proto-Paratethys Sea.","aridification; dust; loess; middle Eocene; Siberian High; winter monsoon","en","journal article","","","","","","","","","","","Applied Geology","","",""

Previous studies have found structural brain alterations in remitted CD patients compared to healthy controls, specifically in the anterior cingulate cortex (ACC). However, potential mechanisms through which these persistent alterations may have occurred are currently unknown. Methods: Structural 3T MRI's from 25 remitted CD patients were linked with gene expression data from neurotypical donors, derived from the Allen Human Brain Atlas. Differences in gene expression between the ACC and an unaffected control cortical region were examined, followed by a Gene Ontology (GO) enrichment analysis. A cell type enrichment analysis was conducted on the differentially expressed genes, and a disease association enrichment analysis was conducted to determine possible associations between differentially expressed genes and specific diseases. Subsequently, cortisol sensitivity of these genes in existing datasets was examined. Results: The gene expression analysis identified 300 differentially expressed genes in the ACC compared to the cortical control region. GO analyses found underexpressed genes to represent immune function. The cell type specificity analysis indicated that underexpressed genes were enriched for deactivated microglia and oligodendrocytes. Neither significant associations with diseases, nor evidence of cortisol sensitivity with the differentially expressed genes were found. Discussion: Underexpressed genes in the ACC, the area vulnerable to permanent changes in remitted CD patients, were often associated with immune functioning. The specific lack of deactivated microglia and oligodendrocytes implicates protective effects of these cell types against the long-term effects of cortisol overexposure.","Anterior cingulate cortex; Cushing's disease; Gene expression; Structural MRI","en","journal article","","","","","","","","","","","Pattern Recognition and Bioinformatics","","",""

The goal of this paper is to investigate the extent to which empirical models provide more accurate estimations of actual energy consumption when compared to a theoretical building energy model, in order to estimate average actual energy savings of renovations. We used the Dutch non-profit housing stock to demonstrate the results. We examined three empirical models to predict the actual energy consumption of dwellings: a linear regression model, a non-linear regression model, and a machine learning model (GBM). This paper shows that these three models alleviate the performance gap by giving a good prediction of actual energy consumption on sectoral cross-sections. However, these models still have shortcomings when predicting the effects of specific renovation interventions, for example newly introduced heat pumps. The non-linear and machine learning model (GBM) outperform the theoretical model in terms of estimating energy savings through renovation interventions.","Actual energy consumption; Empirical prediction models; Energy performance; Non-profit housing","en","journal article","","","","","","","","","","","Housing Quality and Process Innovation","","",""

In this study a Graph theory based method is developed and applied for efficiently identifying the most critical elements. The main advantage of this method is that it avoids the need to perform elaborate hydrodynamic model calculations. Instead, the structure of the network is the main starting point. The results show that the structure of the network is more decisive than the hydraulics with respect to the criticality of the system’s performance as a whole. Results depict that the suggested approach is applicable not only to the main (primary) network, but also to the capillaries which are normally beyond the scope of the traditional methods applied so-far because of the complexity of the networks and the required calculation time.","asset management; critical elements; deterioration; drinking water distribution networks; Graph theory; leakages; maintenance","en","journal article","","","","","","","","","","","Sanitary Engineering","","",""

Hematite, which is a cheap and sustainable semiconductor material with excellent chemical properties, a favourable band gap (2.1 eV) and composed of earth abundant elements is a suitable model photoanode material for studying OER. To understand the design of energy efficient anodes, it is highly desirable to have mechanistic insight into OER at an atomistic level which can be directly connected to experimentally measured quantities. We present a multiscale computational model of OER which connects the thermodynamics and kinetics of elementary charge transfer reactions in OER to kinetics of OER at laboratory length and time scales. We couple density functional theory (DFT) and DFT based molecular dynamics (DFT-MD) simulations with solvent effects at an atomistic level with kinetic Monte Carlo (kMC) simulations at a coarse-grained level in our multiscale model. The time and applied bias potential dependent surface coverage, which are experimentally not known, and the O2 evolution rate during OER at the hematite-water interface are calculated by the multiscale model. Furthermore, the multiscale model demonstrates the effect of explicitly modelling the interaction of water with the electrode surface via direct adsorption.

The hippocampus is a prominent glucocorticoid target and expresses both the glucocorticoid receptor (GR: Nr3c1) and the mineralocorticoid receptor (MR: Nr3c2). These nuclear steroid receptors act as ligand-dependent transcription factors. Transcriptional effects of glucocorticoids have often been deduced from bulk mRNA measurements or spatially informed individual gene expression. However, only sparse data exists allowing insights on glucocorticoid-driven gene transcription at the cell type level. Here, we used publicly available single-cell RNA sequencing data to assess the cell-type specificity of GR and MR signaling in the adult mouse hippocampus. The data confirmed that Nr3c1 and Nr3c2 expression differs across neuronal and non-neuronal cell populations. We analyzed co-expression with sex hormones receptors, transcriptional coregulators, and receptors for neurotransmitters and neuropeptides. Our results provide insights in the cellular basis of previous bulk mRNA results and allow the formulation of more defined hypotheses on the effects of glucocorticoids on hippocampal function.","corticosteroid receptors; hippocampus; single-cell RNA sequencing; stress hormones; transcription regulation","en","journal article","","","","","","","","","","","Pattern Recognition and Bioinformatics","","",""

Currently, there is no consensus regarding the inclusion of regions of central necrosis during volume of interest (VOI) delineation for radiomic analysis. The aim of this study was to assess how central necrosis affects radiomic analysis in PET. Methods: Forty-three patients, either with non-small cell lung carcinomas (NSCLC, n = 12) or with pheochromocytomas or paragangliomas (PPGL, n = 31), were included retrospectively. VOIs were delineated with and without central necrosis. From all VOIs, 105 radiomic features were extracted. Differences in radiomic features between delineation methods were assessed using a paired t-test with Benjamini-Hochberg multiple testing correction. In the PPGL cohort, performances of the radiomic models to predict the noradrenergic biochemical profile were assessed by comparing the areas under the receiver operating characteristic curve (AUC) for both delineation methods. Results: At least 65% of the features showed significant differences between VOIvital-tumour and VOIgross-tumour (65%, 79% and 82% for the NSCLC, PPGL and combined cohort, respectively). The AUCs of the radiomic models were not significantly different between delineation methods. Conclusion: In both tumour types, almost two-third of the features were affected, demonstrating that the impact of whether or not to include central necrosis in the VOI on the radiomic feature values is significant. Nevertheless, predictive performances of both delineation methods were comparable. We recommend that radiomic studies should report whether or not central necrosis was included during delineation.","Central necrosis; Radiomics; Tumour delineation; [F]FDG PET/CT","en","journal article","","","","","","","","","","Biomechanical Engineering","","","",""

However, questions arise about how to model and calculate circular buildings components. We develop an LCA model for circular building components in four steps. First, we elaborate on the CE principles and LCA standards to identify requirements and gaps. Second, we adapt LCA standards and propose the ‘Circular Economy Life Cycle Assessment’ (CE-LCA) model. Third, we test the model by assessing an exemplary building component: the Circular Kitchen (CIK). Finally, we evaluate the CE-LCA model with 44 experts. In the CE-LCA model, building components are considered as a composite of parts and materials with different and multiple use cycles; the system boundary is extended to include these cycles, dividing the impacts using a circular allocation approach. The case of the CIK shows that the CE-LCA model supports an ex-ante assessment of circular building components in theoretical context; it makes an important step to support the transition to a circular built environment.","Allocation; assessment method; Building component; Circular Economy (CE); Life Cycle Assessment (LCA); Multi-cycling","en","journal article","","","","","","","","","","","Housing Management","","",""

However, surprisingly, although in recent years more attention has been focused on studying quality failures and reducing their causes, such failures still frequently occur in building energy renovation projects. In practice, the causes are not isolated, but rather, stem from complex correlations that impede high-quality performance. Due to their neglect of the causal relationships among these factors in quality failures, project coordinators have been unsuccessful in managing the quality of construction projects. Considering a network of different causes, this work reports on efforts to identify and manage the causes of quality failures in construction processes. A new understanding of the nature of these causes was achieved by considering four sources of data: literature review, opinions of experts, interpretive structural modeling (ISM), and focus groups. Our analysis shows that not only do many causes directly influence construction quality in building energy renovation projects, but also these causes interact with each other. It is noteworthy that external causes remain associated with all internal causes. Drivers of these causes are lack of experienced project managers, unauthorized changes in design documents, incomplete building information in projects, and poor onsite coordination; eliminating them enables solutions to a number of other internal causes. Finally, solutions are proposed to improve the current situation. These solutions fall into the categories of people, materials and equipment, design, and organization, based on the quality management process. The findings of this work provide valuable information for helping both policy makers and practitioners adopt effective policies and measures to manage the construction quality of building energy renovation projects.","Building energy renovation; Causes; Interpretive structural model (ISM); Quality failures; Quality management","en","journal article","","","","","","Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2021-09-13","","","Housing Quality and Process Innovation","","",""

Residential energy retrofitting in China mostly focuses on multi-owner residential buildings with composite ownership that dozens of private homeowners own their apartment and jointly own the common parts of a building. The implementation of residential energy retrofit faces many risks, causing the slow retrofit process in the hot summer and cold winter (HSCW) zone of China. Transaction cost theory (TCT) is conducive to enrich an in-depth understanding of risk inventories in the energy retrofitting context. This paper aims to explore the key risks in retrofit projects of residential buildings in the HSCW zone with transaction costs (TCs) considerations, in order to provide the direction for effective risk management. First, based on the theoretical risks with TCs considerations, interviews were conducted to adjust the risk list and to connect these risks with stakeholders and stages. Second, a questionnaire survey was made based on two parameters of risk probability and severity, and then ten top risks were chosen as key risks through both a risk matrix and Borda count. The results show that most of the key risks are associated with homeowners and contractors, involving retrofit awareness, cooperation performance, opportunism, professional expertise, construction management, safety management, and maintenance, of which most occur at the stage of on-site construction. Information cost is the largest source of TCs relevant to these key risks and is mainly borne by the government and homeowners. TCs can also provide a lens for the retrofitting in other countries to understand risks, and the decrease in information costs contributes to effective risk management both in China and in the international context.","Energy retrofit; Risk management; Stakeholders; Transaction costs","en","journal article","","","","","","","","","","","Housing Quality and Process Innovation","","",""

In public debate in the Netherlands, too high ambitions and a ‘piling-up’ of policy objectives are often mentioned as causes of non-conformance of quantitative housing objectives. However, despite such non-conformance, a plan or policy may still function well by informing the decision-making process and invoking scrutiny of conflicting objectives. This paper aims to understand how municipalities cope with the implementation of housing developments with pluralistic policy objectives. Therefore, the performance of the policy objective to accelerate the production of housing is studied by exploring how value conflicts between this quantitative and qualitative objectives are addressed. A survey among Dutch municipalities and two additional in-depth case studies reveal that the non-conformance of the acceleration of the housing production not only results from exogenous processes, but is also a result of accumulating policy decisions favouring qualitative ambitions. The case studies reveal that municipalities especially struggle with trade-offs between qualitative and quantitative objectives.

Detailed insight is provided for dwellings with different heat pump systems and for dwellings with different building characteristics. Further research to determine the energy performance of dwellings with specific heat pump configurations is recommended in light of the energy transition in the built environment.","energy consumption; Heat pump systems; housing stock; non-profit housing","en","journal article","","","","","","","","","","","Design & Construction Management","","",""

The main reason is that a specific Fault Detection and Diagnosis (FDD) setup is time-consuming and expensive because the existing methods are component-specific, not aligned with HVAC design practices, and not fully automated. 4S3F (four symptoms three faults) method, based on system engineering and Diagnostic Bayesian Networks (DBN), was proposed to decrease the gap between the design of HVAC systems for buildings and energy performance diagnosis, and proofs of concepts were tested on diverse parts of the HVAC system of one specific building. In order to test the further applicability potential of the method, it is necessary to expand these tests and to study possible problems arising in practice, like the lack of sensors installed in a specific system or practical difficulties in the construction of the 4S3F Bayesian network by HVAC or control. However, due to the small number of validations carried out on the environment, parameters, and installation process of this method still need further discussion and refinements. In this paper, we investigate how to construct the DBN for the quite generic AHU (Air Handling Unit) of a, with mechanical supply and exhaust, heating and cooling coils, and heat recovery. The paper describes the possible DBN's depending on the technical design and the measurement points. The diverse Bayesians networks are compared, and it is concluded that also, with a limited number of sensors, a diagnostic network can be set up. It is also concluded that step-by-step instructions would be needed to facilitate the work of HVAC engineers when setting up the diagnosis model.","Bayesian network; building energy performance; building energy diagnostics","en","conference paper","TU Delft OPEN Publishing","","","","","","","","","","Building Energy Epidemiology","","",""

However, this decrease is found to be lower than energy performance models predicted. One of the possible reasons is the behaviour of the residents, which is partially determined by the thermal comfort preferences of these residents. In this paper, the relationship between thermal comfort perception, indoor climate and energy consumption is investigated using high-resolution measurement data in 93 dwellings in the Netherlands. In the OPSCHALER project, data about thermal comfort perception, indoor climate and operational energy consumption were collected in 93 dwellings in the Netherlands during periods ranging from two to twelve months over a period of two years. Comfort perception was registered using the Comfort App, an application where users record their comfort data. Indoor climate data were collected per five minutes using sensors for temperature, relative humidity and CO2 concentration in the living room, kitchen and bedrooms of the dwellings. The Comfort App asked the residents for the room they are in, their comfort perception, their activities during the last half hour and the amount of clothing they wear. Significant relationships were found between thermal sensation and thermal preference, clothing level, metabolic activity level, activities related to thermal comfort taken in the last half hour, and indoor air temperature. These data can be used to compare the comfort level registered by the residents with the comfort level predicted by the PMV model, and link this to the indoor climate and the energy consumption for heating. This information can help to understand the relations between user preferences, indoor climate and energy consumption for heating.","Thermal comfort; indoor climate; dwellings; comfort theory","en","conference paper","TU Delft OPEN Publishing","","","","","","","","","","Building Energy Epidemiology","","",""

However, the relationship between games and attitude change in civil servants remains unexplored. This paper aims at identifying factors leading to attitude change of civil servants. As hardly any paper is focused on civil servants' attitude change through games, the authors broaden their research to attitude change through games in general. Out of 483 documents, 19 reference papers were analyzed in detail. Eighty-one games were found, and more than 13 different theories were identified containing 30 different influencing factors, which were found mostly to be unrelated and context-dependent. The conceptual dispersion between studies indicates that the resulting overview of factors is a first step towards creating a uniform theory. The results can help governments to design better games.","","en","book chapter","IGI Global","","","","","Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2023-07-01","","Engineering, Systems and Services","Transport and Logistics","","",""

It remains unclear how individual Teneurins form macromolecular cis- and trans-synaptic protein complexes. Here, we present a 2.7 Å cryo-EM structure of the dimeric ectodomain of human Teneurin4. The structure reveals a compact conformation of the dimer, stabilized by interactions mediated by the C-rich, YD-shell, and ABD domains. A 1.5 Å crystal structure of the C-rich domain shows three conserved calcium binding sites, and thermal unfolding assays and SAXS-based rigid-body modeling demonstrate that the compactness and stability of Teneurin4 dimers are calcium-dependent. Teneurin4 dimers form a more extended conformation in conditions that lack calcium. Cellular assays reveal that the compact cis-dimer is compatible with homomeric trans-interactions. Together, these findings support a role for teneurins as a scaffold for macromolecular complex assembly and the establishment of cis- and trans-synaptic interactions to construct functional neuronal circuits.","","en","journal article","","","","","","","","","","","BN/Dimphna Meijer Lab","","",""

Concurrently, zinc smelters generate waste residues containing significant amounts of iron and zinc which are stored or landfilled. The zinc concentration of iron and steelmaking residues inhibits its recycling to the blast furnace but is insufficient to be sent directly to the zinc producers. Consequently, a means of up-concentration is required. The pilot HIsarna ironmaking furnace has shown potential for processing secondary iron-bearing resources. Furthermore, zinc can be concentrated in the off-gas flue dust, providing an enriched input for zinc smelters. The potential recyclability of blast furnace (BF) and basic oxygen furnace (BOF) dust and ‘goethite’ residue from the zinc industry has been studied. The input materials have been comprehensively characterized and their reduction–vaporization behavior, has been investigated. Individual samples were tested at temperatures of up to 1300 °C. Here, it was shown that minimal reduction of iron and volatilization of zinc occurred in the goethite and BOF samples. Conversely, even at 1000 °C, the BF dust showed complete reduction of iron and removal of zinc within 30 min. This was due to its high carbon content (40 wt%) which can act as a reductant. Consequently, mixtures of BOF dust and goethite with BF dust were studied. It has been shown that mixtures of 30:70 BF dust to goethite and 20:80 BF dust to BOF dust are suitable for recovering zinc to the gas phase and fully reducing the contained iron.

There are many circular design options for building components and knowledge about which options perform better – from an environmental perspective – is limited. Existing guidelines focussed on single components, single circular design options, applied different assessment methods and provide conflicting guidelines. Therefore, in this article, we develop environmental design guidelines by comparing multiple circular design options for two building components: a kitchen (short service life) and renovation façade (medium service life). First, we synthesize design variants based on distinct circular pathways, such as renewable-, non-virgin material use, and modularity for reuse. Second, we compare their environmental performance to a ‘business-as-usual’ variant through Material Flow Analysis (MFA) and a multi-cycle Life Cycle Assessment (LCA) including extensive sensitivity analysis on circular parameters. Analysing the 78 LCAs and MFAs, we derive 8 lessons learned on the environmental design of circular building components. We compare our findings to existing guidelines, including those for circular building structures (long service life). Amongst other lessons, we found components with a short service life benefit more from prioritizing circular design options to slow and close future cycles, whilst components with a longer service life benefit more from reducing resources and slowing loops on site. However, applying circular design options does not always result in a better environmental performance. Tipping-points were identified based on the number of use cycles, lifespans and the assessment methods applied.","(CE); (LCA); (MFA); Building components; Circular economy; Design guidelines; Life cycle assessment; Material flow analysis; Multi-cycle","en","journal article","","","","","","","","","","","Real Estate Management","","",""

It is found that continuous mode of injection is the most suitable method to increase the spread of particles and also to reduce the exerted pressure on the slag surface. Placing dent-like obstacles at the tip of the chute significantly increases the impact area, especially for batchwise injection, thus reducing force and pressure on the slag surface that minimizes the risk of liquid splash.

In this regard, simulation of different imaging conditions using specialized phantoms is increasingly being investigated. In this study, the design and evaluation of a modular multimodality imaging phantom to simulate heterogeneous uptake and enhancement patterns for radiomics quantification in hybrid imaging is presented. Methods: A modular multimodality imaging phantom was constructed that could simulate different patterns of heterogeneous uptake and enhancement patterns in positron emission tomography (PET), single-photon emission computed tomography (SPECT), computed tomography (CT), and magnetic resonance (MR) imaging. The phantom was designed to be used as an insert in the standard NEMA-NU2 IEC body phantom casing. The entire phantom insert is composed of three segments, each containing three separately fillable compartments. The fillable compartments between segments had different sizes in order to simulate heterogeneous patterns at different spatial scales. The compartments were separately filled with different ratios of 99mTc-pertechnetate, 18F-fluorodeoxyglucose ([18F]FDG), iodine- and gadolinium-based contrast agents for SPECT, PET, CT, and T1-weighted MR imaging respectively. Image acquisition was performed using standard oncological protocols on all modalities and repeated five times for repeatability assessment. A total of 93 radiomic features were calculated. Variability was assessed by determining the coefficient of quartile variation (CQV) of the features. Comparison of feature repeatability at different modalities and spatial scales was performed using Kruskal-Wallis-, Mann-Whitney U-, one-way ANOVA- and independent t-tests. Results: Heterogeneous uptake and enhancement could be simulated on all four imaging modalities. Radiomic features in SPECT were significantly less stable than in all other modalities. Features in PET were significantly less stable than in MR and CT. A total of 20 features, particularly in the gray-level co-occurrence matrix (GLCM) and gray-level run-length matrix (GLRLM) class, were found to be relatively stable in all four modalities for all three spatial scales of heterogeneous patterns (with CQV < 10%). Conclusion: The phantom was suitable for simulating heterogeneous uptake and enhancement patterns in [18F]FDG-PET, 99mTc-SPECT, CT, and T1-weighted MR images. The results of this work indicate that the phantom might be useful for the further development and optimization of imaging protocols for radiomic quantification in hybrid imaging modalities.","3D printing; hybrid imaging; multimodality imaging; phantom studies; radiomics; repeatability","en","journal article","","","","","","","","","","","EMSD AS-south Project engineers","","",""

Among the materials that can be recycled, there is steel scrap which is fed to the furnace bath through an inclined chute. The velocity distribution of the scrap particles along the chute affects the particles’ distribution on the liquid slag and, thereupon, the efficient operation of the reactor. In this study, the flow of steel scrap particles along an inclined chute with the same dimensions as those of the actual chute of the HIsarna plant is investigated experimentally and numerically. The simulations are validated using chute tip velocity and mass fractions collected at the different compartments of a sampling device. Translational and angular velocity distributions along and across the chute are reported, and the effect of different parameters are investigated. The impact of the shape of the particles on the simulation process is found to be negligible. The angular velocity distribution in cross-sections of the chute exhibited a V-shaped orientation, whereas the translational velocity displayed similar values across the cross-sections. Moreover, translational velocity appeared to increase with increasing inclination angles, whereas angular velocity increased with decreasing batch size.","discrete element methods; granular flow; HIsarna Ironmaking; steel scrap chute; steel scrap flowability","en","journal article","","","","","","","","","","","Team Yongxiang Yang","","",""

Correct and reliable predictions become even more important once the aim is to go from small- to large-scale processes to establish an industrial demonstrations. In this study, a CFD-based scale-up of HIsarna off-gas system based on the Eulerian–Lagrangian approach is investigated and detailed step in scale-up procedure is discussed. A three-dimensional CFD model is developed and validated based on the available pilot scale data and used to design and scale up the post-combustion chamber (also known as reflux chamber). Detailed kinetics for volumetric and gas–solid reactions are incorporated in validated CFD model with a special attention to the wall boundary condition and modeling. The effect of reflux chamber geometry, oxygen injection ports, oxygen injection flowrate, isolation wall thickness, and inlet flue gas composition on different system characteristics such as heat loss through the wall, CO–H2–carbon mixture conversion, flue gas, and wall temperature are investigated. The aim of the scaled up geometry, like pilot scale, is to achieve full combustion of unwanted species inside the reflux chamber to assure zero emissions from the off-gas system. Compared to the pilot scale, the scaled up reflux chamber is capable of handling and removing higher amount of unwanted species coming from the main reactor and therefore lower CO–H2 and carbon particle emissions, mainly due to a larger size which provides larger volume and residence time for volumetric and gas–solid reaction to proceed.","","en","journal article","","","","","","","","","","","Team Yongxiang Yang","","",""

To benchmark energy performance, a set of indicators is created that adequately represents the performance of Dutch housing associations according to the changed policies. A process involving key stakeholders is presented here to identify, assess and combine possible indicators. These were then integrated into four integrated models, which led to a final benchmark model. A model was chosen that consists of three indicators covering the energy performance of Dutch housing associations. The process and arguments that led to this final model are presented.

To date, treatment effects for these symptoms are often limited. Nocebo effects (i.e., negative outcomes that are not attributable to active treatment components) have a substantial influence on treatment success and can be established via learning through classical conditioning. Therefore, interventions aimed at reducing nocebo effects by means of counterconditioning, in which an alternative association (inhibiting the previous association) is learned, could be a promising method for improving physical symptoms. In experimental studies, counterconditioning has been shown promising in reducing experimentally-induced nocebo effects on pain and itch. Application of counterconditioning procedures to reduce nocebo effects on clinical symptoms has yet to be researched. This paper provides a protocol of a 6-week counterconditioning intervention aimed at reducing nocebo effects and clinical pain in patients with fibromyalgia. A study in patients with fibromyalgia is proposed to examine the feasibility and potential effectiveness of this counterconditioning intervention as a novel treatment method for reducing nocebo effects and generalization to clinical pain symptoms. Results can help design an optimized treatment protocol for reducing nocebo effects, based on the experiences of participants and the first indications of treatment efficacy.","classical conditioning; counterconditioning; nocebo effects; open-label; persistent physical symptoms","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

However, evolutionary predictions are increasingly being developed and used in medicine, agriculture, biotechnology and conservation biology. Evolutionary predictions may be used for different purposes, such as to prepare for the future, to try and change the course of evolution or to determine how well we understand evolutionary processes. Similarly, the exact aspect of the evolved population that we want to predict may also differ. For example, we could try to predict which genotype will dominate, the fitness of the population or the extinction probability of a population. In addition, there are many uses of evolutionary predictions that may not always be recognized as such. The main goal of this review is to increase awareness of methods and data in different research fields by showing the breadth of situations in which evolutionary predictions are made. We describe how diverse evolutionary predictions share a common structure described by the predictive scope, time scale and precision. Then, by using examples ranging from SARS-CoV2 and influenza to CRISPR-based gene drives and sustainable product formation in biotechnology, we discuss the methods for predicting evolution, the factors that affect predictability and how predictions can be used to prevent evolution in undesirable directions or to promote beneficial evolution (i.e. evolutionary control). We hope that this review will stimulate collaboration between fields by establishing a common language for evolutionary predictions.","disease modelling; evolution; evolutionary control; models; population genetics; predictability; prediction","en","review","","","","","","","","","","BN/Bionanoscience","BN/Liedewij Laan Lab","","",""

To reduce this effort, networks, network forcing and/or the flow in networks are often simplified and analysed using the Graph Theory. The simplification options depend on the network characteristics. There are many topological features to describe Graph-based networks. In this paper, these characteristics are summarised, applied on 7 urban drainage networks and discussed. As the topological features do not describe the networks in a uniform manner, a new type of topological characterisation of looped drainage networks (Network Linearisation Parameter, NLP) is proposed based on linearized hydraulics and bottlenecks identified in paths to outfalls.","Asset management; Graph Theory; linearized hydraulics; maintenance; network analysis; network structure; network topology; urban drainage networks","en","journal article","","","","","","","","","","","Sanitary Engineering","","",""

Approval of pharmaceutical products is the responsibility of the European Medicines Agency, whereas authorizing the placing on the market of medical devices is decentralized to independent 'conformity assessment' organizations called notified bodies. The first legal basis for an EU system of evaluating medical devices and approving their market access was the medical device directives, from the 1990s. Uncertainties about clinical evidence requirements, among other reasons, led to the EU Medical Device Regulation (2017/745) that has applied since May 2021. It provides general principles for clinical investigations but few methodological details-which challenges responsible authorities to set appropriate balances between regulation and innovation, pre- and post-market studies, and clinical trials and real-world evidence. Scientific experts should advise on methods and standards for assessing and approving new high-risk devices, and safety, efficacy, and transparency of evidence should be paramount. The European Commission recently awarded a Horizon 2020 grant to a consortium led by the European Society of Cardiology and the European Federation of National Associations of Orthopaedics and Traumatology, that will review methodologies of clinical investigations, advise on study designs, and develop recommendations for aggregating clinical data from registries and other real-world sources.

First, it is unclear how widely used and understood the behavior is in the Vélib’ system; pointing to the need for an ethnographic study.

METHODS: Nocebo effects on pressure pain were first experimentally induced in 83 healthy female participants through conditioning with open-label instructions about the pain-worsening function of a sham TENS device to assess susceptibility to nocebo hyperalgesia. Participants were then randomized to 1 out of 2 nocebo-reduction conditions (counterconditioning/extinction) or to continued nocebo-conditioning (control), each combined with open-label instructions about the new sham device function. Dispositional optimism, trait and state anxiety, pain catastrophizing, fear of pain, and body vigilance were assessed at baseline. RESULTS: The results showed that lower optimism and higher trait anxiety were related to a stronger induction of nocebo hyperalgesia. Moreover, a stronger induction of nocebo hyperalgesia and higher trait anxiety predicted a larger nocebo reduction across interventions. Also, nocebo hyperalgesia and optimism moderated the effects of the nocebo-reduction interventions, whereby larger nocebo hyperalgesia and lower optimism were associated with a larger nocebo reduction after counterconditioning, compared with control, and also extinction for larger nocebo hyperalgesia. DISCUSSION: Our findings suggest that open-label conditioning leads to stronger nocebo hyperalgesia when trait anxiety is high and dispositional optimism is low, while these psychological characteristics, along with larger nocebo hyperalgesia, also predict open-label counterconditioning to be an effective nocebo-reduction strategy. Susceptibility to nocebo hyperalgesia, trait anxiety, and dispositional optimism might be indicators of a flexible pain regulatory system.","Nocebo effect; pressure pain; hyperalgesia; prediction; counterconditioning","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

The aim is to investigate the possibility of predicting the thickness of the refractory material by using other parameters that are possible to measure during the operation. A combination of FEM and CFD modeling is used to develop a methodology for detailed wall modeling and refractory material loss prediction. Finite element method (FEM) analysis is used to obtain the thermal properties of the wall using detailed geometries for variable refractory thickness. The obtained properties are then used to build CFD models to study the effect of refractory thickness on wall heat loss, temperature and composition profiles.

Intervention content, design and implementation as well as lessons learnt are presented in the hopes of guiding other research groups working on similar projects.
Methods: Numerous approaches were used and combined to support the development of the Perfect Fit virtual coach. Approaches include literature reviews, empirical studies, collaboration with end-users, content and technical development sprints, interdisciplinary collaboration and iterative proof-of-concept implementation. Findings: The Perfect Fit intervention integrates evidence-based behavioral change techniques as well as new techniques focused on identity change, big data science, sensor technology and personalized real-time coaching. Intervention content of the virtual coaching matches communication preferences and individual needs of end users. Lessons learnt include ways to optimally implement and tailor interactions from the virtual coach (e.g., ‘explain why user is asked for input’, ‘tailor timing and frequency of intervention components’). With regards to the development process, lessons learnt include strategies for effective interdisciplinary collaboration and technical development (e.g., ‘Find a good balance between wishes of end-users and legal possibilities’).
Discussion: The Perfect Fit development process was interactive, iterative and challenging at times. We hope
that our experiences and lessons learnt can inspire and benefit others.","","en","abstract","","","","","","","","","","","Interactive Intelligence","","",""

By employing evaporation assisted self-assembly, we form opal-like structures with micro-sized magnetic superball particles. We study the structure formation of different superball shapes during evaporation of a dispersion droplet with in-situ small angle x-ray scattering with microradian resolution in the absence and presence of an external magnetic field. In the absence of a magnetic field, strong shape-dependent structures form as the water evaporates from the system. Applying a magnetic field to the droplet has a unique effect on the system; strong magnetic fields inhibit the growth of well-ordered assemblies due to the formation of out-of-equilibrium dipolar structures while lower magnetic fields allow particles to rearrange and orient without inhibition. In this work, we show how the superball assembly inside a droplet can be controlled by the magnetic field strength and the superball shape. The tunability of these parameters not only enables the controllable formation of macroscopic colloidal assemblies but also opens up possibilities for the development of functional materials with tailored properties on a macro-scale.","self-assembly; small-angle x-ray scattering (SAXS); magnetic colloids","en","journal article","","","","","","","","","","","ChemE/Advanced Soft Matter","","",""

As nanocrystals (NCs), the material is also of interest for biological and physical applications. Unfortunately, as with most phosphors, with the reduction in size comes a large reduction of the photoluminescence quantum yield (PLQY), which is typically associated with an increase in surface-related PL quenching. Here, we report the synthesis of bipyramidal Yb:YLF NCs with a short axis of 60 nm. We systematically study and remove all sources of PL quenching in these NCs. By chemically removing all traces of water from the reaction mixture, we obtain NCs that exhibit a near-unity PLQY for an Yb3+ concentration below 20%. At higher Yb3+ concentrations, efficient concentration quenching occurs. The surface PL quenching is mitigated by growing an undoped YLF shell around the NC core, resulting in near-unity PLQY values even for fully Yb3+-based LiYbF4 cores. This unambiguously shows that the only remaining quenching sites in core-only Yb:YLF NCs reside on the surface and that concentration quenching is due to energy transfer to the surface. Monte Carlo simulations can reproduce the concentration dependence of the PLQY. Surprisingly, Forster resonance energy transfer does not give satisfactory agreement with the experimental data, whereas nearest-neighbor energy transfer does. This work demonstrates that Yb3+-based nanophosphors can be synthesized with a quality close to that of bulk single crystals. The high Yb3+ concentration in the LiYbF4/LiYF4 core/shell nanocrystals increases the weak Yb3+ absorption, making these materials highly promising for fundamental studies and increasing their effectiveness in bioapplications and optical refrigeration.","core/shell; energy transfer; luminescence; nanocrystals; optical refrigeration; rare earth ions; ytterbium","en","journal article","","","","","","","","","","","ChemE/Opto-electronic Materials","","",""

The ratio of the storage and discharge capacities of the subsystems determines the performance. The performance of the urban water system may deteriorate as a result of the change in the ratio of storage to discharge capacity due to aging, urbanisation and climate change. We developed the graph-based weakest link method (GBWLM) to analyse urban drainage systems. Flow path analysis from graph theory is applied instead of hydrodynamic model simulations to reduce the computational effort. This makes it practically feasible to analyse urban drainage systems with multi-decade rainfall series. We used the GBWLM to analyse the effect of urban water system aging and/or climate scenarios on flood extent and frequency. The case study shows that the results of the hydrodynamic models and the GBWLM are similar. The rainfall intensities of storm events are expected to increase by approximately 20% in the Netherlands due to climate change. For the case study, such an increase in load has little impact on the flood frequency and extent caused by gully pots and surface water. However, it could lead to a 50% increase in the storm sewer flood frequency and an increase in the extent of flooding.","","en","journal article","","","","","","","","","","","Sanitary Engineering","","",""

Current interventions mainly diminish stress and anxiety during procedures, while stress and anxiety often build up at home. Moreover, interventions often focus on either distraction or preparation. eHealth can combine multiple strategies and provide a low-cost solution that can be used outside the hospital. Objective: To develop an eHealth solution to diminish preprocedural stress and anxiety, and to evaluate the app on use, usability and user experience in practice. We also aimed to gain in-depth insights in children's and caregivers' opinions and experiences to inform future improvements. Methods: This is a multi-study report on the development (Study 1) and evaluation (Study 2) of a first version of the developed app. In study 1 we adopted a participatory design approach in which children's experiences were central to the design process. We performed an experience journey session with stakeholders (n = 13) to map the child's outpatient journey, identify pains and gains, and formulate the desired experience journey. Iterative development and testing with children (n = 8) and caregivers (n = 6) resulted in a working prototype. The prototype was tested with children, resulting in a first version of the Hospital Hero app. The app was evaluated on use, user-experience and usability during an eight-week pilot study in practice (Study 2). We triangulated data from online interviews with children and caregivers (n = 21) and online questionnaires (n = 46). Results: Multiple stress and anxiety experience touchpoints were identified. The Hospital Hero app supports children in their hospital journey by facilitating preparation at home and providing distraction at the hospital. The pilot study showed that the app was evaluated positively on usability and user-experience and is considered feasible. Qualitative data showed five themes: (1) user-friendliness, (2) coherence and power of storytelling, (3) motivation and reward, (4) fit with real hospital journey, (5) procedural comfort. Discussion: Using participatory design, we developed a child-centered solution that supports children in the entire hospital journey and may diminish preprocedural stress and anxiety. Future efforts should create a more tailored journey, define an optimal engagement window and formulate implementation strategies.","anxiety; co-creation; coping; eHealth; participatory design (PD); procedural comfort","en","journal article","","","","","","","","","","","Design Aesthetics","","",""

Nocebo effects on itch and pain have shown to be induced by conditioning with thermal heat stimuli and reduced by counterconditioning. However, open-label counterconditioning, in which participants are informed about the placebo content of the treatment, has not been investigated, while this can be highly relevant for clinical practice. Furthermore, (open-label) conditioning and counterconditioning has not been investigated for pain modalities relevant to musculoskeletal disorders, such as pressure pain. Methods: In a randomized controlled trial, we investigated in 110 healthy female participants whether nocebo effects on pressure pain combined with open-label verbal suggestions can be (1) induced via conditioning and (2) reduced via counterconditioning. Participants were allocated to either a nocebo- or sham-conditioning group. Next, the nocebo group was allocated to either counterconditioning, extinction or continued nocebo conditioning; sham conditioning was followed by placebo conditioning. Results: Nocebo effects were significantly larger after nocebo conditioning than sham conditioning (d = 1.27). Subsequently, a larger reduction of the nocebo effect was found after counterconditioning than after extinction (d = 1.02) and continued nocebo conditioning (d = 1.66), with effects similar to placebo conditioning (following sham conditioning). Conclusions: These results show that (counter)conditioning combined with open-label suggestions can modulate nocebo effects on pressure pain, which provides promise in designing learning-based treatments to reduce nocebo effects in patients with chronic pain disorders, particularly for musculoskeletal disorders. Significance: Few studies have investigated the efficacy counterconditioning to reduce nocebo effects. Whereas typically deceptive procedures are used, these are not ethically appropriate for use in clinical practice. The current study demonstrates that open-label counterconditioning in a pain modality relevant for many chronic pain conditions may be a promising new strategy for reducing nocebo effects in a non-deceptive and ethical manner, which provides promise in designing learning-based treatments to reduce nocebo effects in patients with chronic pain disorders.","","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

Methods: A participatory user-centered design approach was employed, involving end-users and other stakeholders throughout the study. The approach consisted of four phases. Semi-structured interviews and a survey were conducted to understand user needs and reasons for poor adherence (Phase 1: define). Key themes were identified, leading to the formulation of behavior change strategies and design and game requirements. Several design directions were ideated, resulting in a concept for a serious game (Phase 2: ideate). Two rounds of user-tests were performed to evaluate a prototype of the serious game in terms of usability, perceived impact on medication adherence and motivation (Phase 3: prototype and Phase 4: evaluate). Results: Findings from semi-structured interviews (n = 6) and the online survey (n = 20) revealed that people’s non-adherence was often attributed to the perception of asthma as an episodic condition, the delayed experienced effect of maintenance inhalers, and lack of knowledge regarding difference of effect between maintenance and reliever inhalers. The study used behavior change strategies to translate these insights into design requirements for the development of the narrative-based persuasive game Ademgenoot. This six-week challenge-based game combines various behavior change strategies, including personal goal setting and continuous visual feedback, as well as persuasive game design elements, such as a narrative and rewards, with the aim of enhancing motivation to adhere to their medication regimen. User-testing (n = 8; round 1 and 2) showed that Ademgenoot is feasible in clinical practice and has the potential to support people with mild asthma in adherence to their maintenance medication. Discussion: Future efforts should be directed towards a larger evaluation to assess the impact on motivation and inhaler use behaviour. Plain Language Summary: The goal of this study was to create a serious game that encourages people with asthma to take their medication regularly. During the study, we worked closely with individuals who have asthma and other stakeholders throughout the study. We conducted interviews and surveys to understand why people have difficulties using their maintenance inhaler as prescribed by their doctor. Based on the feedback we received, we developed a serious game called “Ademgenoot”. The game uses information on inhaler use automatically collected with a device attached to the inhaler. The game includes features like personal goals and visual feedback on inhaler use to motivate users to take their medication consistently. We tested a prototype of the game with users to see if it was easy to use and if it motivated them to use their maintenance inhaler. The results showed that Ademgenoot is a viable option for helping individuals with mild asthma stay on track with their medication.","adherence monitoring; behavior change; medication adherence; participatory design; serious game design","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

A major reason for this poor adoption is the generic, one-size-fits-all approach taken by designers of these interventions, without addressing the needs, skills, and preferences of disadvantaged groups. Participatory design approaches are effective for developing interventions that fit the needs of specific target groups; yet, very little is known about the practical implications of executing a participatory design project for and with people with LHL. Objective: This study aimed to demonstrate the application of participatory design activities specifically selected to fit the needs and skills of people with LHL and how these were manifested within an overarching eHealth design process. In addition, the study aims to present reflections and implications of these activities that could support future designers to engage people with LHL in their design processes. Methods: We used the design process of a smart asthma inhaler for people with asthma and LHL to demonstrate participatory design activities. The study was framed under 5 stages of design thinking: empathize, define, ideate, prototype, and test within 2 major iteration cycles. We integrated 3 participatory design activities deemed specifically appropriate for people with LHL: co-constructing stories, experience prototype exhibition, and video prototype evaluation. Results: Co-constructing stories was found to deepen the understanding of the participant’s motivation to use or not to use maintenance medication. This understanding informed and facilitated the subsequent development of diverse preliminary prototypes of possible interventions. Discussing these prototypes in the experience prototype exhibition helped provoke reactions, thoughts, and feelings about the interventions, and potential scenarios of use. Through the video prototype evaluation, we were able to clearly communicate the goal and functionality of the final version of our intervention and gather appropriate responses from our participants. Conclusions: This study demonstrates a participatory design approach for and with patients with asthma and LHL. We demonstrated that careful consideration and selection of activities can result in participants that are engaged and feel understood. This paper provides insight into the practical implications of participatory activities with people with LHL and supports and inspires future designers to engage with this disadvantaged target group.","asthma; eHealth; health care; health literacy; low health literacy; medication; medication adherence; mHealth; participatory design; participatory medicine; OA-Fund TU Delft","en","journal article","","","","","","","","","","Biomechanical Engineering","Design Aesthetics","","",""

On day 1, conditioned group received six administrations of intranasal insulin with a conditioned stimulus (CS; smell of rosewood oil), whereas the control group received a placebo with the CS. On day 2, both groups received a placebo spray with the CS. Glucose, insulin, and C-peptide were repeatedly measured in blood. Hunger and memory were assessed with validated measures. Results Intranasal insulin stabilized dropping glucose levels in patients (B = 0.03, SE = 0.02, p =.027) and healthy men (B = 0.046, SE = 0.02, p =.021), and decreased C-peptide levels in healthy controls (B = 0.01, SE = 0.001, p =.008).

Potentially, their magnitude might be higher in patients with chronic pain compared to healthy controls since patients likely experience treatment failure more frequently. The current study investigated group differences in the induction and extinction of nocebo effects on pressure pain at baseline (N = 69) and 1-month follow-up (N = 56) in female patients with fibromyalgia and matched healthy controls. Nocebo effects were first experimentally induced via classical conditioning combined with instructions on the pain-increasing function of a sham transcutaneous electrical nerve stimulation device, then decreased via extinction. One month later, the same procedures were repeated to explore their stability. Results suggest that nocebo effects were induced in the healthy control group during baseline and follow-up. In the patient group, nocebo effects were only induced during follow-up, without clear group differences. Extinction was only observed during baseline in the healthy control group. Further comparisons of nocebo effects and extinction indicated no significant changes across sessions, possibly suggesting their overall magnitudes were stable over time and across groups. In conclusion, contrary to our expectations, patients with fibromyalgia did not have stronger nocebo hyperalgesia; instead, they might be less responsive to nocebo manipulations than healthy controls. Perspective: The current study is the first to investigate group differences in experimentally manipulated nocebo hyperalgesia between chronic pain and healthy populations at baseline and 1-month follow-up. Since nocebo effects are common in clinical settings, their investigation in different populations is essential to explain and minimize their adverse effects during treatment.","classical conditioning; fibromyalgia; hyperalgesia; Nocebo effect; pressure pain","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

Cortisol varies not only in response to stress but also as part of a diurnal rhythm. It shows a particularly sharp increase immediately after awakening, the cortisol awakening response (CAR). Cortisol can be affected by medication, but it is less clear whether it can also be affected by learning. Animal studies have consistently shown that cortisol can be affected by pharmacological conditioning, but the results in humans have been mixed. Other studies have suggested that conditioning is also possible during sleep and that the diurnal rhythm can be conditioned, but these findings have not yet been applied to cortisol conditioning. Objective: The objective of our study was to introduce a novel avenue for conditioning cortisol: by using the CAR as an unconditioned response and using scent conditioning while the participant is asleep. This study investigates an innovative way to study the effects of conditioning on cortisol and the diurnal rhythm, using a variety of devices and measures to make measurement possible at a distance and at unusual moments. Methods: The study protocol takes 2 weeks and is performed from the participant’s home. Measures in week 1 are taken to reflect the CAR and waking under baseline conditions. For the first 3 nights of week 2, participants are exposed to a scent from 30 minutes before awakening until their normal time of awakening to allow the scent to become associated with the CAR. On the final night, participants are forced to wake 4 hours earlier, when cortisol levels are normally low, and either the same (conditioned group) or a different (control group) scent is presented half an hour before this new time. This allows us to test whether cortisol levels are higher after the same scent is presented. The primary outcome is the CAR, assessed by saliva cortisol levels, 0, 15, 30, and 45 minutes after awakening. The secondary outcomes are heart rate variability, actigraphy measures taken during sleep, and self-reported mood after awakening. To perform manipulations and measurements, this study uses wearable devices, 2 smartphone apps, web-based questionnaires, and a programmed scent device. Results: We completed data collection as of December 24, 2021. Conclusions: This study can provide new insights into learning effects on cortisol and the diurnal rhythm. If the procedure does affect the CAR and associated measures, it also has potential clinical implications in the treatment of sleep and stress disorders.","conditioning; cortisol; cortisol awakening response; olfactory learning; sleep","en","journal article","","","","","","Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2023-09-18","","","Applied Ergonomics and Design","","",""

We conducted an empirical study where 63 participants ordered a drink with an app which presented a different level of information about the delivery person (nothing; name and photo; heart rate). Initial results show no significant impact on empathy measures between conditions, however post-hoc analysis showed that heart rate lead to increased Compassionate and decreased Affective empathy.

However, data release faces barriers due to limited support of civil servants, whereas the literature neglects civil servants' role in opening data. This paper aims at understanding why civil servants can be reluctant to support the disclosure of data. The authors developed a model to explain civil servants' behavioral intention to open data. Design/methodology/approach: The authors test a series of hypotheses by collecting and analyzing survey data from 387 civil servants and by applying multivariate hierarchical regression. Findings: The results indicate the factors influencing the behavior of civil servants. Social influences, performance expectancy, data management knowledge and risks have a significant influence. Personal characteristics control these effects. Research limitations/implications: Caution is needed to generalize the findings towards the support to open data provision by civil servants. Though the analyzed sample was limited to Brazil, other countries and cultures might yield different outcomes. Larger and more diversified samples might indicate significant effects on variables not found in this research. Practical implications: The insights can be used to develop policies for increasing the support of civil servants towards governmental data disclosure. Originality/value: This study suggests factors of influence to civil servants' behavior intentions to disclose governmental data. It results in a model of factors, specifically for their behavioral intention at the individual level.","Adoption; Attitude; Barriers; Behavior; Learning; Open data; Open government","en","journal article","","","","","","Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.","","2023-09-09","","Engineering, Systems and Services","Transport and Logistics","","",""

We aimed to investigate the impact of the pandemic on the in-hospital diagnostic pathway of breast cancer (BC) and colorectal cancer (CRC). Methods: 71,159 BC and 48,900 CRC patients were selected from the Netherlands Cancer Registry. Patients, diagnosed between January 2020 and July 2021, were divided into six periods and compared to the average of patients diagnosed in the same periods in 2017–2019. Diagnostic procedures performed were analysed using logistic regression. Lead time of the diagnostic pathway was analysed using Cox regression. Analyses were stratified for cancer type and corrected for age, sex (only CRC), stage and region. Results: For BC, less mammograms were performed during the first recovery period in 2020. More PET-CTs were performed during the first peak, first recovery and third peak period. For CRC, less ultrasounds and more CT scans and MRIs were performed during the first peak. Lead time decreased the most during the first peak by 2 days (BC) and 8 days (CRC). Significantly fewer patients, mainly in lower stages, were diagnosed with BC (−47%) and CRC (−36%) during the first peak. Conclusion: Significant impact of the COVID-19 pandemic was found on the diagnostic pathway, mainly during the first peak. In 2021, care returned to the same standards as before the pandemic. Long-term effects on patient outcomes are not known yet and will be the subject of future research.","breast cancer; colorectal cancer; COVID-19; diagnosis; diagnostic pathway; diagnostic procedures; lead time; population based","en","journal article","","","","","","","","","","RST/Radiation, Science and Technology","","","",""

In the past years, single-cell datasets of the hypothalamus have contributed immensely to the current understanding of the diverse hypothalamic cellular composition. While the PVN has been adequately classified functionally, its molecular classification is currently still insufficient. To address this, we created a detailed atlas of PVN transcriptomic cell types by integrating various PVN single-cell datasets into a recently published hypothalamus single-cell transcriptome atlas. Furthermore, we functionally profiled transcriptomic cell types, based on relevant literature, existing retrograde tracing data, and existing single-cell data of a PVN-projection target region. Finally, we validated our findings with immunofluorescent stainings. In our PVN atlas dataset, we identify the well-known different neuropeptide types, each composed of multiple novel subtypes. We identify Avp-Tac1, Avp-Th, Oxt-Foxp1, Crh-Nr3c1, and Trh-Nfib as the most important neuroendocrine subtypes based on markers described in literature. To characterize the preautonomic functional population, we integrated a single-cell retrograde tracing study of spinally projecting preautonomic neurons into our PVN atlas. We identify these (presympathetic) neurons to cocluster with the Adarb2+ clusters in our dataset. Further, we identify the expression of receptors for Crh, Oxt, Penk, Sst, and Trh in the dorsal motor nucleus of the vagus, a key region that the pre-parasympathetic PVN neurons project to. Finally, we identify Trh-Ucn3 and Brs3-Adarb2 as some centrally projecting populations. In conclusion, our study presents a detailed overview of the transcriptomic cell types of the murine PVN and provides a first attempt to resolve functionality for the identified populations.","hypothalamus; neuroendocrine; paraventricular; preautonomic; single-cell","en","journal article","","","","","","","","","","","Pattern Recognition and Bioinformatics","","",""

(TU Delft Design & Construction Management)","","2024","The 2050 decarbonization goals coupled with the growing housing shortage in Europe intensify the pressure on new-build dwellings to enhance their energy performance. Beyond a zero operational energy, the focus has shifted towards reducing embodied carbon (EC). Against this backdrop, this study investigates the simultaneous impact of downsizing and the use of timber in new-build dwellings, EC reduction strategies seldom explored concurrently. Through partial life cycle assessments, three scenarios are modelled: the Small, Medium, and Large House, with two construction variations for each, comparing a modular timber design to a conventional concrete alternative. Designs are based on dwellings built in Almere, the Netherlands. Data is extracted from the Swiss Ecoinvent database using the TOTEM tool and the static −1/+1 approach for biogenic carbon accounting is adopted. Results show a total EC ranging from 42,608 to 70,384 kgCO2eq for the timber designs versus 54,681 to 91,270 kgCO2eq for their concrete counterparts. Findings suggest that the relationship between house size and EC is sublinear whereby a house twice the size entails less than twice the EC emissions. Only the simultaneous implementation of downsizing and the use of timber achieved 53% carbon savings. The discussion explores implications of outcomes across academic, industry and policy perspectives, challenges in implementing smaller timber dwellings, and study limitations and future research. Beyond its empirical contribution, this paper offers a practical contribution with its hierarchical data analysis approach covering building, element and component. This approach can be implemented by researchers and practitioners alike to inform their design process.","Embodied carbon; Life cycle assessment; Timber construction; Downsizing; House size; Housing","en","journal article","","","","","","","","","","","Urban Development Management","","",""

In the case of silicon, properties such as disorder and energy separation of conduction band valleys are commonly investigated individually upon modifications in selected parameters of the material stack. However, this reductionist approach fails to consider the interdependence between different structural and electronic properties at the danger of optimising one metric at the expense of the others. Here, we achieve a significant improvement in both disorder and valley splitting by taking a co-design approach to the material stack. We demonstrate isotopically purified, strained quantum wells with high mobility of 3.14(8) × 105 cm2 V−1 s−1 and low percolation density of 6.9(1) × 1010 cm−2. These low disorder quantum wells support quantum dots with low charge noise of 0.9(3) μeV Hz−1/2 and large mean valley splitting energy of 0.24(7) meV, measured in qubit devices. By striking the delicate balance between disorder, charge noise, and valley splitting, these findings provide a benchmark for silicon as a host semiconductor for quantum dot qubits. We foresee the application of these heterostructures in larger, high-performance quantum processors.","","en","journal article","","","","","","","","","","","QCD/Scappucci Lab","","",""

Methods: Participants were randomly assigned for additional use of a mobile educative application or standard counselling alone. Main outcome measures were adherence to aspirin measured by two validated questionnaires: Simplified Medication Adherence Questionnaire (SMAQ), Believes and Behaviour Questionnaire (BBQ), and patients reported tablet intake >90%. Results: A total of 174 women with an indication for aspirin during pregnancy were included. The questionnaires were filled in by 126 out of the 174 participants (72.4%). Similar results were found in the app group and the standard counselling groups for both validated questionnaires. Tablet intake >90% was seen in 88.7% and 87.5% (p = 0.834) of the app group and standard counselling group respectively. Subgroup analyses demonstrated a negative effect of BMI and a positive effect of educational level on adherence. Conclusions: Our study revealed no added effect of a novel, mobile educative application to standard counselling on aspirin adherence during pregnancy. Tablet intake was equally high in both groups probably explained by our high educated population. Innovation: Future studies should focus on tailored counselling on medication to pregnant women's needs including medication reminders, addressing concerns, adequate health literacy and side effects, offering rewards to further stimulate aspirin adherence in pregnancy with optimal outcome for mother and their neonate.","Adherence; Aspirin; Counselling; Education; Educative application; Pregnancy","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""
