(copromotor); Delft University of Technology (degree granting institution)","2024","This study investigates the impact of smartphone use on passengers' comfort during travel, focusing on train trips. The literature review reveals that smartphones have become the primary activity for train passengers, leading to discomfort and potential musculoskeletal issues, particularly in the neck, shoulders, arms, and back. The study aims to enhance the vehicle seat environment to alleviate these issues.
A questionnaire was administered to passengers, revealing that the main smartphone activities include listening to music, watching videos, reading, and texting. Most passengers prefer using smartphones with arm support, although a high discomfort score related to armrest use was noted. The study suggests exploring smartphone holders for watching videos and improving armrests for texting.
Passenger needs for the seating environment were collected through context mapping and co-creation techniques. Different age groups showed varied preferences in smartphone activities, with younger passengers and employees primarily using smartphones for entertainment, while older individuals engaged in diverse activities. The study emphasizes the importance of arm support, charging facilities, Wi-Fi, and considerations for special passenger groups like the disabled in future interior designs.
Chapters 5, 6, and 7 discuss design aspects to enhance smartphone comfort. An adjustable armrest is recommended, and experiments suggest an optimal trunk angle for smartphone use. A specially designed armrest reduced neck discomfort but increased discomfort in the upper arms, emphasizing the need for adjustable height. Chapter 8 provides specific recommendations for armrest height levels during various smartphone activities and proposes the use of smartphone holders.
In conclusion, the study suggests implementing adjustable armrests, smartphone holders, and considering the duration of smartphone use in future vehicle interior designs. These improvements aim to enhance body posture and reduce discomfort for passengers during smartphone usage. Further testing with end-users is recommended to validate these proposed solutions.","passengers; seat; comfort; design; smartphone use","en","doctoral thesis","","978-94-6366-811-8","","","","","","","","","Applied Ergonomics and Design","","",""

Compensating the weight of the hands is complex since the level of support depends on both wrist and forearm orientations. To explore simplified approaches, two different weight compensation strategies (constant and linear) were compared to the theoretical ideal sinusoidal profile and no compensation in eight healthy subjects using a mechanical wrist support system. All three compensation strategies showed a significant reduction of 47–53% surface electromyography activity in the anti-gravity m. extensor carpi radialis. However, for the higher palmar flexion region, a significant increase of 44–61% in the m. flexor carpi radialis was found for all compensation strategies. No significant differences were observed between the various compensation strategies. Two conclusions can be drawn: (1) a simplified torque profile (e.g., constant or linear) for weight compensation can be considered as equally effective as the theoretically ideal sinusoidal profile and (2) even the theoretically ideal profile provides no perfect support as other factors than weight, such as passive joint impedance, most likely influence the required compensation torque for the wrist joint.","biomechanics; design; exoskeletons; intelligent orthotics","en","journal article","","","","","","","","","","","Mechatronic Systems Design","","",""

This is argued to be necessary both in order to maintain the sustainability and efficiency of these programs, but also due to the fact that further integration of humans into technical systems provides the only effective means to bridge gaps in functionality and governance. However, Sorgner’s position is entirely insensitive to the design turn in applied ethics, which argues against the neutrality of technology, instead maintaining that technology and society co-construct each other with persistent feedback loops. This, I argue, is a problem for his account inasmuch as technologies, as they become more ubiquitous, likewise become pervasive and inextricable from our sociotechnical infrastructures. As such, less-than-beneficent forces, as current trends illustrate, can appropriate these seemingly banal infrastructures to gear them towards oppressive ends, thereby ultimately threatening the social democracies that Sorgner’s position aims to buttress.","Algocracy; authoritarianism; technocracy; applied ethics; design","en","journal article","","","","","","","","","","","Ethics & Philosophy of Technology","","",""

A low-intrusive monitoring system is based on a person’s use of energy or water. Objective: The study's objective was to provide a systematic overview of studies that monitor the health and well-being of older people using energy (eg, electricity and gas) and water usage data and study the outcomes on health and well-being. Methods: CENTRAL, Embase, MEDLINE (Ovid), Scopus, Web of Science, and Google Scholar were searched systematically from inception until November 8, 2021. The inclusion criteria were that the study had to be published in English, have full-text availability, target independent-living people aged 60 years and older from the general population, have an observational design, and assess the outcomes of a monitoring system based on energy (ie, electricity, gas, or water) usage on well-being and safety. The quality of the studies was assessed by the QualSyst systematic review tool. Results: The search strategy identified 2920 articles. The majority of studies focused on the technical algorithms underlying energy usage data and related sensors. One study was included in this review. This study reported that the smart energy meter data monitoring system was considered unobtrusive and was well accepted by the older people and professionals involved. Energy usage in a household acted as a unique signature and therefore provided useful insight into well-being and safety. This study lacked statistical power due to the small number of participants and the low number of observed events. In addition, the quality of the study was rated as low. Conclusions: This review identified only 1 study that evaluated the impact of an energy usage monitoring system on the well-being and safety of older people. The absence of reliable evidence impedes any definitive guidance or recommendations for practice. Because this emerging field has not yet been studied thoroughly, many questions remain open for further research. Future studies should focus on the further development of a monitoring system and the evaluation of the implementation and outcomes of these systems.

Various techniques to visualize information, such as two- and three-dimensional graphs, diagrams, and models, not only expand our capacity to work with different types of information but also actively recruit our visual–spatial thinking. Data physicalization is emerging as a beginner-friendly approach to construct information visualization. Mapping intangible data onto tangible artifacts that possess visual, spatial, and physical properties demands an interplay of spatial thinking and hands-on manipulation. Much existing literature has explored using formatted infographics to aid learning and spatial thinking development. However, there is limited insight into how children may leverage their spatial thinking to create information visualizations, particularly tangible ones. This case study documented the data physicalization activities organized in two design classrooms of an international school in Netherlands, with 37 children aged 11–12. Seven themes relevant to spatial thinking were identified from multimodal evidence gathered from the data physicalization artifacts, classroom videos and recordings of children’s making process, and semi-structured interviews with children. Our findings suggested that these children generated various ideas to create visual–spatial forms for data with the materials at hand, such as mapping quantities to tangible materials of different sizes, using spatial ordinal arrangement, and unitizing materials to set visual parameters. Meanwhile, they evaluated and adjusted the visual–spatial properties of these materials according to the numerical data they had, crafting feasibility, and others’ spatial perspectives. What was particularly interesting in our findings was children’s iteration on their visual–spatial understandings of the intangible numerical values and the tangible materials throughout the embodied making processes. Overall, this study illustrated the different types of spatial thinking children applied to create their data physicalizations and offered insights into how embodied experiences accompanying the open-ended visualization challenge allowed children to explore and construct spatial understandings.","spatial thinking; data physicalization; embodied cognition; information visualization; primary education; design; making","en","journal article","","","","","","","","","","","Science Education and Communication","","",""

To overcome technical issues related to the implementation of color filters (CFs) on PV modules, like glare and color instability, colorimetry metrics, such as the hue, chroma, luminance color space, and the quantitative concept of difference between two colors are extensively deployed. It is showcased in this work that designing colored modules with high hue and chroma stability is possible by using a front-side texturing with edged geometry, like V-shaped grooves and inverted pyramids, while obtaining colors with relatively high luminance values, indicating good brightness. Furthermore, it is argued that adapting the rear surface of the front glass with a random textured layout where the CF is applied can improve color and luminance stability without significant loss of chroma while eliminating glare. Finally, the models can be used to optimize the number of layers for a given CF, reducing unnecessary optical losses.

This promises a coherent foundation for explaining how we deploy technologies in design, in particular with respect to the affordances they create. By connecting the categorization of technologies to the matching of user effectivities to features of the environment in affordances, the paper proposes an approach to the transparent description of the assemblages produced by design in terms of which technologies are involved and how they connect to each other, to the wider environment and to users. For affordances, this improves specificity concerning the features of the environment that are directly relevant to an interaction and the connections between these features and the rest of the environment. With respect to technologies, it helps understand not only why a technology may be used under certain circumstances but also abuse and underperformance. Finally, it supports design by providing means for parsing complex situations into chains of technologies between animals and environments. This helps explain how technologies modify effectivities, environments or relations between the two and how this affects design performance.

The principle behind this solution is that fibrereinforced plastic has better mechanical properties per kilogram of material than steel.

Emissions are expected to increase due to increasing waste generation, particularly in countries still landfilling biodegradable wastes. As a complementary measure to gas extraction with subsequent flaring or energy conversion, or for emissions reduction from old landfills or from landfills containing wastes with a low gas potential, microbial methane oxidation systems (MMOS) are considered a promising technology. Numerous studies relating to controlling factors and enhancement of microbial methane oxidation in biocovers, biowindows or biofilters, both in laboratory and in large scale field settings, have been published. The design of optimized MMOS requires thorough understanding of the involved processes, specifically the biological ones and of those related to the transport of gas and water in porous media, and of the impact of material properties and external environmental factors on these processes. Consequently, the selection of materials that are suitable from a biogeochemical and from a geotechnical point of view, meeting the required water and gas transport properties, are key aspects in the design process. This paper reviews the scientific background of the relevant concepts and processes dictating MMOS performance, and provides guidance on layout and design steps, including choice of materials and quality control. Further, a decision tree to support the choice of MMOS is proposed.

(TU Delft Marketing and Consumer Research)","","2022","Higher education (HE) students experience rates of depression and anxiety substantially higher than those found in the general population. Many psychological approaches to improving wellbeing and developing student resilience have been adopted by HE administrators and educators, especially during the Covid-19 pandemic. This article aims to review literature regarding integration of resilience and wellbeing in HE. A subsequent aim is to scope toward developing foundations for an emerging discipline specific concept–designer resilience. A literature scoping review is applied to chart various conceptual, theoretical and operational applications of resilience and wellbeing in HE. Twenty-seven (27) articles are identified and analysed. The scoping review finds that two general approaches to implementing resilience and wellbeing training exist in HE. First, articles reacting to a decline in student mental health and remedying this decline through general extra-curricular resilience or wellbeing programmes. Second, articles opting for a curricula and discipline-specific approach by establishing why resilience will be needed by future graduates before developing and testing new learning experiences. The presence of cognitive flexibility, storytelling, reframing and reflection lie at the core of the practice of resilience and design and therefore offer preliminary opportunities to develop ‘designer resilience’ training.

(TU Delft Applied Ergonomics and Design); Boess, S.U. (TU Delft Applied Ergonomics and Design)","","2022","There is an increasing acknowledgement of the role of residents in the success of low- or zero-energy renovations. One of the approaches to improve this factor is by influencing resident behaviour by means of devices for feedback on consumption. The goal of these systems is to help residents make sense of the relation between their actions and choices, and their energy consumption, indoor environmental conditions and comfort. In this paper we describe interactions with these devices as one form of data encounter. We then suggest that there are other forms of data encounters already happening in renovated homes by which residents make sense. These data encounters are useful to understand if we want to understand the interactions between residents and buildings. We introduce the concepts of sense-making and interactive adaptation to better understand these data encounters. In this study we show data encounters in various forms as they happen in four renovated homes in the same building in the Netherlands. We use interviews and video-recorded walkthroughs to identify data encounters related to indoor climate and energy consumption within these homes. We find data encounters that involve more than displays and technical devices. Residents use bodily senses, information from other people, and complex contextual information to understand indoor climate and energy consumption. We also find that data encounters relate to, and are embedded in everyday practices and routines. Finally, we find that data encounters involve active sense-making rather than passive consumption of information. We discuss these findings and conclude by suggesting that existing data encounters could serve as a starting point for the improved design of buildings, renovation processes, and the selection, design and implementation of new data encounters.","Occupant behaviour; data; feedback; renovation; sense-making; design; home energy management systems","en","conference paper","TU Delft OPEN Publishing","","","","","","","","","","Applied Ergonomics and Design","","",""

We found that the partial factor (Formula presented.) in the current Eurocode 2 is about 20% lower than the optimal value and, thus, provides an insufficient safety margin. The obtained optimal partial factor (Formula presented.) in the (modified) Eurocode 2 and MC2010 formulas is 1.53 and 1.36, respectively. The difference stems from higher accuracy and, hence, lower uncertainty of the MC2010 model in predicting experimental results. Hence, on average, the MC2010 formula leads to about 13% larger design resistances compared to Eurocode 2 given that the target reliability for both design formulas is the same.

Door zeespiegelstijging, toename van de hoeveelheid neerslag in een korte tijdspanne, droogteperioden in de zomer, voortschrijdende bodemdaling en zoute kwel hopen de watergerelateerde problemen zich op.

Door dijken, dammen, sluizen en gemalen wordt het waterpeil in dit stelsel gecontroleerd en wordt overtollig water via boezems naar de grote rivieren en de zee afgevoerd. De noodzaak om het water continu te beheren en het laagland te bemalen is evident, maar het systeem is niet voldoende om toekomstige problemen het hoofd te bieden.

From 2017 to 2021, TU Delft conducts this research project. A lot of disciplines of TU Delft are involved from the Faculty of Architecture. The Heritage & Architecture (HA) is in the lead. Four themes are addressed for research: energetic sustainability, financial perspective, functional usability and securing knowledge. Theoretical and analytical research is worked out about the more general aspects of current and future policy and strategies. The perspective for the future is made by practice in four Living Labs on different scale levels. Various tools and methodologies are tested, analysed and improved through eight sub-studies. One of the related research questions for the Living-Labs is: How can student design projects for real cases change the solutions for these projects in practice? So, educational design projects from HA are integrated in the Living Labs. Around ten students (the next generation) work in teams on the subjects. In academic education projects this is not daily practice. The TU Delft HA group developed their own methodology to incorporate practice, technology, design and cultural value aspects in their education program (Clarke & Zijlstra & De Jonge, 2019). At this moment (half way the KaDEr project) some conclusions can be drawn from the results of the students. They can make a difference in practice when dealing with heritage. Buildings that were planned to be demolished will remain like in Zutphen and new insights are provided for preserving historically important aspects in the Reuversweerd estate. The province of Gelderland is enthusiast and in the lay-out for the policy framework in future this way of working will be incorporated in the strategy to safeguard a more sustainable approach on the preservation of built heritage including the ideas of the next generation of architects and researchers.

OBJECTIVE: The objective of this research is to identify the optimal desktop lighting for the comfortable use of the computer screen in a dark environment. METHODS: An experiment was designed where seven illumination setups were introduced for the users to perform their leisure tasks on a computer screen. Fifteen healthy subjects participated in the experiments. During each session, durations of the eye blinks, fixations and saccades of the user were recorded by an eye tracker. His/her neck and trunk movements were recorded by a motion tracking system as well. The comfort/discomfort questionnaire, localized postural discomfort questionnaire, NASA task load index and computer user questionnaire were used to record the overall comfort/discomfort, the local perceived physical discomfort, the cognitive workload, and general/eye health problems, respectively. RESULTS: Subjective and objective measurement results indicated that users felt more comfortable with high intensity warm lights using a computer screen. We also identified that the eye fixation durations, as well as the scores of two questions in the computer user questionnaire, have significant negative correlations with comfort. On the other side, the durations of blinks and the scores of three questions in the computer user questionnaire, were significantly correlated with discomfort. CONCLUSION: The warm (3000K) and high intensity (1500 lux) light reduced the visual and cognitive fatigue of the user and therefore improve the comfort of the user during the use of a computer screen.","design; eye tracking; Light","en","journal article","","","","","","","","","","","Applied Ergonomics and Design","","",""

The birth of this collaboration can be dated in the 1980s and 1990s, with the rise of three different fields of concern on the effects of industrial society: the concern on the environmental impact of industrialization, the concern on the alarming state of affairs of cities in these years, and the rising concern on climate change. The development of a real program of Delta Urbanism
at TU Delft started in 2005, with the International Architecture Biennale Rotterdamon ‘the Flood’, the Katrina disaster in New Orleans and the start of the new Delta Program in the Netherlands as important driving forces. Important in the Delta Urbanism program is the search for a new ‘Darwinistic’ approach, emphasizing the evolutionary character of delta regions, and adaptivity as a main strategy to survive. This approach should substitute the traditional. Reductionist ‘Einstein’ approach, which is fitting in the dominating paradigm of the industrial society.
Delta Urbanism itself can also be considered an evolutionary field of interest: it is under construction continuously. For the future, we can appoint four important issues to be elaborated: a more radical approach of the new adage ‘working with water’, water as a leverage for a complex society in transition; making delta landscapes adaptive, and design as an explorative method.","postindustrial; design; interdisciplinary collaboration; evolutionary; adaptivity","en","journal article","","","","","","","","","","","Urban Design","","",""

The aim of this article is to shed light on these and suggest a possible way forward for design that can ensure AI-powered artifacts remain safe even as their utility evolves over time.
Objective: Our aim was to design a Care Pathway for monitoring the blood pressure of at-risk patients, in order to increase eHealth implementation in secondary preventive care.
Methods: A qualitative design study was used in this research. Data were collected by conducting visual mapping sessions including semistructured interviews with hypertension patients and doctors. The data were transcribed and coded and thereafter mapped into a Care Pathway.
Results: Four themes emerged from the results: (1) the current approach to blood pressure measuring has disadvantages, (2) risk and lifestyle factors of blood pressure measuring need to be considered, (3) there are certain influences of the at-home context on measuring blood pressure, and (4) new touchpoints between patients and health professionals need to be designed. These in-depth insights combined with the visualization of the current blood pressure process resulted in our Care Pathway design for monitoring the blood pressure of at-risk patients as secondary preventive care.
Conclusions: The Care Pathway guides the implementation of eHealth devices for blood pressure self-measurement. It showcases the pathway of at-risk patients and increases their involvement in managing their blood pressure. It serves as a basis for a new service using eHealth.","eHealth; blood pressure monitoring; at-risk patients; secondary preventive care; care pathway; design","en","journal article","","","","","","","","","","","Methodologie en Organisatie van Design","","",""

Current surgical lighting systems have a fixed shape illumination pattern, whereas the wound and surroundings have a variable shape and characteristics. A lighting system that is able to adapt its shape and light distribution to the characteristics of the wound might improve visual performance. This paper describes the development of a new concept for lighting using bendable strips with LEDs. The basic idea of placing LEDs on a bendable surface is very simple and elegant. To achieve a functional system, the effects of the different design choices, such as shape of the strips, number of LEDs, number of strips, and LED power were investigated. The influence of these choices is evaluated by simulation using a computational model to identify the optimal parameters for the design. The final design is evaluated using the computational model and a physical prototype consisting of one luminaire segment. The system is able to produce light fields that can have fairly complex shapes at a good range of different sizes. Recommendations about aspects like spot size and strip number are given. The physical test model indicates that the calculated system functions close to how it would in a real-life situation. Given the results, it expected that a system, which is able to modify the light field in real time and that requires minimal control effort, could improve lighting in the operating room.","adaptable; Concept; design; surgical luminaire; visual comfort","en","journal article","","","","","","","","","","","Medical Instruments & Bio-Inspired Technology","","",""

(TU Delft Environmental Technology and Design); van Campenhout, Ignace (Gemeente Rotterdam)","","2019","Although severely altered, the urban subsurface is the base of the natural system, and is crucial for a stable, green, healthy, and liveable city. It is also the technical space, the engine room of the city where vital functions such as water, electricity, sewers, and drainage are located. This hybrid state needs to be recognized when designing resilient and durable (subsurface) infrastructure within urban renewal projects, so as to properly employ the parameters of both natural and technical systems. Interdisciplinary work is needed in order to be able to link natural systems (a) the water cycle, (b) soil and subsurface conditions, (c) soil improvement technology, and (d) opportunities for urban renewal (e.g. urban growth or shrinkage) in an efficient way.
The importance of implementing “boundary spanning” when doing interdisciplinary work that deals with the effects of climate change is a widely recognized method, and has been an object of study in the city of Rotterdam in the past decade. The particular need for a “distributed agency” became clear during several research projects dealing with climate change, because it enables different actors to contribute to the development of the project at different phases. The representation of the city as both a natural and technical construction has been tested through the use of 2D and 3D information, which has played a significant role in enabling designs to incorporate the dimension of the subsurface. 2D and 3D information needs to anticipate different scales of specific planning and/or design phases, and they must also address various topics of the subsurface. For each phase of urban development, the distributed agency between 2D and 3D information is investigated and reflected upon. Conclusions are then drawn on the relationship between 2D and 3D information, and how it could relate in a productive, boundary spanning act that is inclusive of the subsurface. Based on these potential connections, the design of a new concept which implements boundary spanning as a facilitator is presented.

It focuses on how certain characteristics of urban form can support an urban environment's capacity to self-organize, enabling emergent features to appear that, while unplanned, remain highly functional. The main thrust of the work is to unpack how elements of the urban fabric might be considered as elements of a complex system and then identify how one might design these elements in a more deliberate manner, such that they hold a greater embedded capacity to respond to changing urban forces. The research is predicated on the notion that, while such responses are both imbricated with, and stewarded by human actors, the specificities of the material characteristics themselves matter. Some forms of material environments hold greater intrinsic physical capacities (or affordances) to enact the kinds of dynamic processes observed in complex systems than others (and can, therefore, be designed with generating these affordances in mind). The Ph.D.'s primary research question is thus:
What physical and morphological conditions need to be in place within an urban environment in order for Complex Adaptive Systems dynamics to have an opportunity to arise - such that the physical components (or ‘building blocks') of the urban environment have an enhanced capacity to discover functional configurations in space and time as a response to unfolding contextual conditions?

The proposed metrics provide means to exploit the relationship between the topology, operation, and robustness performance of power grids. They are experimentally validated using models of power grids, and applied on IEEE power systems, synthetically generated power grids, and real world power grids. The proposed metrics assist grid operators for dynamical optimization of flow and topology of a given power grid, and grid analysts in strategic asset management and network expansion planning processes for the purpose of robustness enhancement of a power grid.","robustness; power grids; complex networks; cascading failures; metrics; design; infrastructure protection","en","doctoral thesis","","","","","","","","2015-10-27","Technology, Policy and Management","Multi Actor Systems","","","",""

The design standard of river levee had been traditionally done based on so called shape based specification, where levee is judged to be safe as long as a section satisfies the specified dimensions. In 2002, this policy had been changed and a new inspection guideline which is based on the modern soil mechanics principles had been introduced. The method mainly consists of the non-stationary seepage analysis followed by the circular slip line stability analysis. The exit gradient and uplift pressure are also checked based on specified safety factors. The way of the safety assessment is that, first a river is divided into so called a continuous strip (CS) which is judged to have similar configurations, geotechnical and hydraulic conditions. The typical length of a CS is half to several km long. Then a representative cross section (RCS) that is considered to represent all the CS section is selected. At RCS, detailed soil investigations are carried out, and the inspection is done to assess the safety of the section for stability and piping. A CS is judged to be safe if all the verification items satisfy the specified safety factor, but judged to be NG (no good) if any of the items could not fulfill the threshold value. The first round assessment at year 2011 indicated, only 60% of the all levee is judged to be safe for all verification items. 25% of the levee could not satisfy the stability requirement, 30% piping requirement, and 14% the both requirements. In the paper, the details of the verification methods are described. Furthermore, some recent flood events are introduced.

Later, we analyzed this issue empirically. We first studied existing metrics in viewpoint diversity research of the computer science literature. We also extended these metrics by adding a new one, namely minority access from media and communication studies. After conducting an empirical study for Dutch and Turkish Twitter users, we showed that minorities cannot reach a large percentage of users in Turkish Twittersphere. We also analyzed software tools and design attempts to combat filter bubbles. We showed that almost all of the tools implement norms required by two popular democracy models. We argue that democracy is essentially a contested concept, and other less popular democracy models should be included in the design of such tools as well.","diversity; filter bubble; value sensitive design; democracy; interdisciplinary; design; viewpoint diversity; computational social science; ethics","en","doctoral thesis","","","","","","","","","Technology, Policy and Management","Values, Technology and Innovation","","","",""

In addition a quasiisotropic wing is designed in order to provide baseline reference data. Each wing design is manufactured and tested in the wind tunnel. Lift and root bending moment coefficient and wing deformation have been measured during the test. Measurements were used to validate the numerical results.

The perception of realism, in particular human-like features, can help facilitate mediated social interaction. The current study investigated the effects of form realism on engagement with and use intentions of social robot embodiments. We have defined (perceived) form realism as the result of the appraisal of features that are perceived as realistic contrasted with those appraised as unrealistic. To test the effects of form realism, we applied the model of interactively perceiving and experiencing fictional characters (I-PEFiC). I-PEFiC explains how users respond to interactive, fictional, humanoid characters, on social robots. In a within-subjects design, participants (N = 29; Mage = 28.8 years, age range 18–56 years) interacted with three different robots built from LEGO Mindstorms, which differed in their degree of designed form realism. Each robot presented itself as a physiotherapy assistant and requested the participant to do several exercises. Results of a structured questionnaire indicated that form realism only played a modest role in the perception of electro-mechanical robots. Instead, the perception of affordances appeared to be crucial for determining engagement and intentions to use social robots.","social robots; realism; engagement; use intentions; design","","journal article","Springer","","","","","","","","Industrial Design Engineering","Industrial Design","","","",""

The model is then compared to the results of experiments on slabs subjected to concentrated loads close to supports. As compared to the Eurocode and the ACI code, the Modified Bond Model leads to a significantly better prediction of the experimental results.

The hybridisation of the two concepts, landscape and infrastructure, seeks to redefine infrastructure beyond its strictly utilitarian definition, while allowing design disciplines to gain operative force in territorial transformation processes. This paper aims to put forward urban landscape infrastructures as a design concept, considering them as armatures for urban development and for facilitating functional, social and ecological interactions. It seeks to redefine infrastructural design as an interdisciplinary design effort to establish a local identity through tangible relationships to a place or region. Urban landscape infrastructures can thereby be used as a vehicle to re-establish the role of design as an integrating practice. This paper positions urban landscape infrastructure design in the contemporary discourse on landscape infrastructures. The space of flows, as opposed to the space of places, is introduced as an impetus to develop the concept of landscape infrastructure into a more comprehensive form of urban landscape architecture. Furthermore, this paper outlines a set of principles typical for urban landscape infrastructure design and suggests three potential fields of operation: transport, green and water landscape infrastructure. The design of these operative landscape structures is a crosscutting field that involves multiple disciplines in which the role of designers is essential.","landscape infrastructure; flowscapes; design; urbanism; transport; green infrastructure; infrastructural urbanism; landscape architecture; systems thinking; architecture; regional design; infrastructure","en","journal article","TU Delft","","","","","","","","Architecture and The Built Environment","Urbanism","","","",""

Gaming as a method for Urban Design: Gaming as a method for Urban Design","Tan, R.E. (TU Delft Urban Design)","Bekkering, H.C. (promotor); Reijndorp, A (copromotor); Delft University of Technology (degree granting institution)","2014","An understanding of cities as open systems whose agents act on them simultaneously from below and above, influencing urban processes by their interaction with them and with each other, is replacing the simplistic debate on urban participation which asks whether cities should be organized bottom-up or top-down. This conceptualization of cities as complex systems calls for new collaborative city-making methods: a combination of collaborative planning (which already embraces various agencies and derives decision-making from negotiations between them) and collaborative design (existing methods rely on rule-based iterative processes which control spatial outcomes). While current collaborative planning methods are open and interactive, they fail to simulate realistic power negotiations in the evolution of the physical environments they plan; collaborative design methods fall short in modelling the decision-making mechanisms of the physical environments they control. This research is dedicated to building an open negotiation and design method for cities as self-organizing systems that bridges this gap.
Gaming as a tool for knowledge creation and negotiation serves as an interface between the more abstract decision-making and material city-making. Rarely involved in the creation of our environment, it has the unexplored potential of combining the socio-spatial dimensions of self-organizing urban processes. Diverse agents, the collaborations and conflicts within and between interest groups, and the parameters provided by topological data can all be combined in an operational form in gaming: potentially a great unifier of multiple stakeholder negotiations and individual design aspirations through which to generate popularly informed policies or design.
The simple language and rules of games will allow jargon-free communication between stakeholders, experts and non-experts alike. The interactive and iterative nature of city gaming encourages the development of collective intelligence, derived from the real lives of players to be redeployed in their real urban futures. Vitally, city gaming enables the negotiation of this future, as players with conflicting interests are given an opportunity to develop compatible, even shared, visions. By transforming serious issues into a playful and engaging (although no less serious) experience, city gaming unlocks difficult conversations and helps to build communities in the long term. The urban design, policy and action plans generated collaboratively through gaming will increase social coherence and local agency, as well as cutting costs and time in urban development processes.
This thesis proposes Generative City Gaming as an innovative urban planning and design method built on the tradition of serious gaming. Going beyond the educational scope of other serious games, the ultimate aim of city gaming is to become operational in urban processes – a goal in the process of making a reality since 2008, when Generative City Gaming was first applied to a real urban questions in the Netherlands, later expanding to Istanbul, Tirana, Brussels, and Cape Town. “Negotiation and Design for the Self-Organizing City” reports on six of the twelve city games played to date which were instrumental in the evolution of the method: Play Almere Haven tested whether a game based on self-organizing mechanisms could provide an urban order; Play Rotterdam questioned whether game-derived design could be implemented in urban renewal of a central Rotterdam neighborhood; Yap-Yaşa was played with real urban stakeholders for transforming Istanbul’s self-built neighbourhoods; Play Noord investigated a masterplan on hold could be fixed by unconventional stakeholders; Play Oosterwold jumped up a scale to test the rules of a flexible urban expansion plan for 4500 hectares; Play Van Gendthallen, was the first to enable stakeholders to make the leap from design to reality within the game process.
The Generative City Gaming method evolves continuously. Every new case tests and proves the applicability of city gaming to a specific urban complexity, while challenging the method to adapt itself and develop new features tailored to tackle each unique urban question. Through use, this gaming method is finding its place within existing city-making procedures in a number of countries. The next big question is whether cyclical and open-ended city gaming can move beyond being a consultancy and research tool to become the principal medium of processing and executing city planning.","gaming; play the city; collaborative planning; urban design; design; Generative City Gaming method","en","doctoral thesis","A+BE | Architecture and the Built Environment","978-94-6186-356-0","","","","","","","","","Urban Design","","",""

The design of such a faired recumbent bicycle is a challenge. The Delft design, called VeloX (Human Power Team (2013)), is a fully-faired monocoque front-driven recumbent bicycle, with minimized air drag and maximized space for a big and strong athlete. However, front driven bicycles have the disadvantage that the front driving induces unwanted steering and that the frontal area of the bicycle cannot be reduced any further. A solution would be rear-wheel steering. A common thought is that a rear-wheel steered bicycle cannot be laterally self-stable, and therefore hard to control. However, recent research (Knoll et al. (2012)) has shown that one can design a rear-wheel steered bicycle which shows a stable forward speed range. Based on these results a rear-wheel steered recumbent bicycle has been designed, within the existing design constraints. Although not self-stable, this design shows a mildly lateral unstable behavior in the desired forward speed range of 0 to 40 m/s (0 to 144 km/h). Computer simulations demonstrate that the bicycle can be stabilized by adding a human controller model (Schwab et al. (2013)) to the bicycle model. For a set of expected lateral perturbations (side wind perturbations) it is shown that rider steer torque stays within human bounds, both in magnitude and in frequency. Future work is dedicated to building and testing a prototype of the design.","bicycle; dynamics; control; design; rear wheel steering","en","conference paper","Elsevier","","","","","","","","Mechanical, Maritime and Materials Engineering","Biomechanical Engineering","","","",""

The issue is that our understanding of UCD either comes from large companies or is developed in an academic setting, without taking SMEs into account. This research project demonstrates that in order to make use of UCD in the context of SMEs, the strengths of SMEs play an important role (such as project-based development, involvement of different internal stakeholders and existing relations) by adding to the existing way of work and making SMEs aware of the opportunities that users and clients present. This dissertation provides understanding of how product innovation takes place different in SMEs in comparison to large companies and discusses the current state of applying UCD in SMEs. In ten different cases where SMEs were supported by design agencies UCD methods that are rather new and un-established within the SME practice are applied in design projects. These cases demonstrate that all UCD methods can be applied in SMEs, but require a different approach to implement them in the daily practice of SMEs. Furthermore, even though all cases started of with a product oriented design brief, many of the results had wide implications for the organization (such as for maintenance and marketing) and not only dealt with products but also with services. The outcome of my research is an approach that aims to support SMEs in applying UCD for product innovation in their daily practice. This approach is a combination of a design process commonly used by SMEs (based on impulses, work with great flexibility and iterations), and three challenges that are faced by SMEs when dealing with UCD (becoming aware of opportunities as they present themselves, learning to apply UCD methods and using UCD in the daily practice), the elements that enable SMEs to make use of UCD within their practice (an engaged entrepreneur, being supported by a UCD expert and how to use the gathered user insights within the organization) and has varying degrees of learning experiences. The resulting knowledge can be employed to inform and inspire SMES and UCD experts in applying UCD in SMEs in order to design new products that better fit the needs and desires of users and clients. This dissertation discusses the changing role for designers when working with SMEs. Due to their nature, SMEs are closely involved in projects and like to participate actively. Therefore, designers no longer act as provides of design solutions, but also as a coach or facilitator for SMEs in applying UCD.","SME; UCD; User-centered Design; innovation; design; small firms","en","doctoral thesis","","","","","","","","","Industrial Design Engineering","Industrial Design","","","",""

Methods can be used to do so in the context of learning - to help teach students how to design on a professional level. Methods can also be used in the context of performance - to help designers perform better at what they already do (well). Methods should be seen as mental tools that influence the thinking patterns and mental models of designers. If we accept that methods function via a designer’s mind, we can see that method usage is a human activity in which the designer is the user. This seems to be an obvious fact to be aware of for a discipline that is characterized by its focus on the user of the products and services they design; yet, quite remarkably, many design researchers have paid little attention to the users of their methods. Instead, most design research is aimed at ‘directly’ improving the design process through methods, often ignoring differences between designers, design contexts and design objects. In this thesis, I argue that an important reason for the current state of design methodology is our marginal understanding of the phenomenon of method usage. The thesis aims to contribute to a more detailed understanding of method usage in design, from the perspective of its central actor: the designer. With that, the thesis hopes to lay a foundation for a more designer-centered methodology that inspires researchers to deliver more valuable and useful methods to the design community and that inspires designers, design educators, design managers and design policy makers to re-think the way they employ and promote design methods in their practices.","design; methodology; method usage; design practice; design education","en","doctoral thesis","","","","","","","","","Industrial Design Engineering","Product Innovation Management","","","",""

Typically, such value is created by having novel product functionality, superior technology, or new customer benefits, but value can also be created by adhering to what is fundamentally important to customers in their lives. Focusing on customers’ happiness is a value proposition of the latter kind. Yet, implementing such an approach requires that designers and marketers have a common understanding of the product’s value proposition, and work together to create authentic value propositions about happiness that will also be compelling in the marketplace. In this article, we draw upon the positive psychology literature and present three propositions of design for happiness that designers and marketers can use to communicate and create value together. Design for happiness means designing business concepts with the aim of building and supporting long-term consumer happiness. The three propositions that we bring forward are: 1) design for fostering social relationships and belongingness, 2) design for meaning in life, and 3) design for making consumers active participants rather than passive observers. These propositions create a shared understanding of what “design for happiness” can contribute to customers, and how it can contribute to profits and sales.","business; design; marketing; wellbeing","en","journal article","Chinese Institute of Design","","","","","","","","Industrial Design Engineering","Product Innovation Management","","","",""

(promotor)","2013","This doctoral thesis proposes ways for the translation of the Lean Thinking (LT) into design practice and research, taking the LT concepts as dimensions to study designers’ behavior across design disciplines. Lean Thinking has its roots in manufacturing, however, as a philosophy of guiding principles of Value creation, LT has been applied to a large variety of processes, people and organizations. Despite the implementation success achieved in several fields of practice and research, the translation of LT Principles to design has several problems to overcome. But as a motivational framework LT provides concepts, which are relevant to the design activity and in particular to the assessment of designers’ behavior and performance. This research takes the LT perspective, adopting the concepts of Lean Principles, such as Value and Flow, and the concept of MUDA (the Japanese word for waste) for studying designers in the context of interaction with stakeholders in design and product development processes. As in the design activity, Value is not completely defined in the beginning of the Value creation process, this thesis claims the importance of adopting Lean Principles within crucial actions for an effective Value definition. The empirical part of this research comprises of case studies in five design disciplines. Based on these studies, the translation of the Lean Principles and MUDA in design leads to categorization systems and to the concept of critical situations. Results integrate a framework of awareness to critical situations and crucial actions in design. This thesis proposes a motivational approach for designers that help them improve performance in Value creation. The framework of awareness provides a meta analysis and challenges designers and developers to reflect upon their thinking and acting and on what prevents them from changing behavior to reach an effective performance. The use of the framework in practice might improve designers’ and developers’ adaptive behavior and so contribute to professional competence and education.","design; lean thinking; translation","en","doctoral thesis","","","","","","","","2013-08-20","Industrial Design Engineering","Product Innovation Management","","","",""

The majority of European ship-design industry concentrates on the development of complex, one-off ‘specials’ for the offshore industry, like dredgers, drill ships, pipelaying ships, et cetera. This industry is complex, not just in terms of the industrial structure but also in the terms of the object. To control the complexity the industry uses large and expansive knowledge bases that support the design, engineering and manufacturing activities. The focus of the academic research in this field is close to practice and dominantly aims at developing knowledge and tools that supports the present engineering practices. As these strategies are aimed at controlling the complexity, they leave very little room for more innovative developments. On the other side of the spectrum there is a ship-design practice that does allow radical ship design: design and engineering from a blank sheet of paper. Not surprising that these projects are laborious and expensive. The space in between those two design strategies seems unaddressed in literature and is only occasionally found in practice. The design of complex structures literature appears to be scarce, even though this is an area where European ship-design industry is heavily involved. We interviewed stakeholders from ship industry, looked into the design literature to describe the present situation and finally performed cases studies in other fields of application for inspiration. Based on the case studies we illustrate an alternative design strategy that leaves more space for innovation without starting from scratch. This focuses on the complex interactions between the different levels of decomposition in a complex structure such as a ship. We will illustrate that the wide range of actors involved in these designs make such a change in industry to a sociotechnical challenge.","ship design; innovation; design; C-K theory","en","conference paper","","","","","","","","","Industrial Design Engineering","Product Innovatie Management","","","",""

Some decisions are based on a range of explicit and material alternatives, others are constructed from implicit ideas about the options we have in mind. In preparing a construction project, creating a vision on how the future would look like appears to be one of the most important activities. This is usually done through design sketches. This paper focuses on the interaction between people and the alternatives they face when make decisions that relate to the built environment. My argument is built upon two research traditions - valuing design from a cognitive perspective and psychological processes of decision making, and exemplary empirical observations from my previous work. First the concepts of architectural design quality and value dimensions of a product are addressed, bringing us back to the essentials of Vitruvius. Then I show how sensemaking and intuitive decision making do justice to the complexity and ambiguity of making design related decisions. In the conclusion I argue that value judgements should be considered as a result of the interaction between a product and an individual person in the context of a group or society. Consequently value judgements are essential in sensemaking processes leading to decisions. They integrate arguments from the heart and the mind, leading to particular preferences among individuals. Since decisions are often considered satisfactory for the moment, but outmoded the next, time plays an essential role in creating meaning of design related situations.","decision making; design; intuition; sensemaking; time","en","conference paper","International Council for Building (CIB)","","","","","","","","Architecture and The Built Environment","Real Estate and Housing","","","",""

To verify if these recommendations can be used when assessing solid slab bridges under distributed and concentrated loads, slabs under a combination of a line load, representing the dead weight, and a concentrated load, representing a wheel load, are tested up to failure. The experimental results are used to assess the ultimate shear which can be carried at the support and the influence of the varied parameters is discussed.

This paper reports the design and the evaluation of products in two categories (rubber duckies and deodorants), with (in)appropriate sensory incongruities of three types: visual-tactual, visual-olfactory and visual-auditory. Participants evaluated the level of surprise felt and the intensity of resulting emotions. They also indicated their overall liking for the products. Both appropriate and inappropriate incongruities were evaluated as surprising as well as confusing. As expected, appropriate incongruities evoked more amusement and were generally favored. Whereas products with visualtactual incongruities showed large differences in ratings on liking and amusement between appropriate and inappropriate incongruities, these differences were smaller for products with visual-auditory and visual-olfactory incongruities. Possibly, the appropriateness of an incongruity is more conspicuous when it is brought about by a conflict between touch and vision than when olfaction or audition are involved.","incongruity; senses; sensory metaphor; surprise; amusement; confusion; humor; product design; design","en","journal article","","","","","","","","","Industrial Design Engineering","Industrial Design","","","",""

In our paper instead, it is thought of to design the light pole as a luminescent solar concentrator photovoltaic (LSC-PV) module with solar cell strips and hence reduce costs of silicon solar cells because concentration effects reduce the area and costs of PV cells when compared to conventional PV modules. In our project different types of LSC-PV systems were simulated, studied and analyzed. We evaluated the performance of LSC-PV elements in flat and cylindrical bent shapes, fit for applications in the pole. The modules were made using commercially available PMMA plastic and contained red lumogen dye throughout the bulk. An important parameter determining the functionality of LSC-PV modules is the optical collection efficiency and modules having values sufficiently above 1 are considered to be economically and optically viable for use in electricity generation. From experiments for a flat LSC-PV with PV cells ate the back and mirrors on non-covered edges, the optical collection efficiency, concentration and electrical conversion efficiency that we have obtained are 19%, 1.9 and 2.9% respectively for a gain of 10. Similarly for a similar arrangement of half-bent LSC-PV shape, optical collection efficiency, concentration and electrical conversion efficiency are 15%, 1 and 2.4% respectively for a gain of 6.7.The losses in bent LSC-PVs are higher than those in the flat (increase of 52.5%), however bent LSC-PVs systems are expected to perform well on both sunny and cloudy days.

Life cycle assessment is methodologically incapable of incorporating the difference in convenience. This article uses the eco-costs/value ratio (EVR), as a method for dealing with the environmental assessment of packaging design alternatives with such unequal ‘soft’ functionality.

This paper presents the results of 20 in-depth interviews with professionals from a variety of disciplines and nations. The conclusion of cumulative analysis is that systems do not witness themselves, but their output deeply affects the mental maps that human beings make of each other, the world around them and their own self. Essential qualities human beings seek when being involved with other beings are defined by granularity and reciprocity in the design of time (duration of engagement, synchronizing performance, integrating rhythms and moments to signify), place (body sense, material interaction, emotional space and situated agency), relation (shared meaning, engagement, reputation and use) and action (tuning, reciprocity, negotiation and quality of deeds). By designing granular interaction in 4 dimensions, reciprocity in witnessing obtains significance and the basis for establishing trust in a variety of presences emerges while human agency acquires potential","wotnessing; presence; trust; technology; design; time; place; action; relation; granularity; reciprocity; agency; mediated presence; collaboration","en","journal article","Springer-Verlag","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

(promotor); Visser, E. (promotor)","2012","Domain-Specific Languages (DSLs) are programming language aimed at a particular problem domain, e.g. banking, database querying or website page lay-outs. Through the use of high-level concepts, a DSL raises the level of abstraction and expressive power of the programmer, and reduces the size of programs. This dissertation covers various aspects of the design and implementations of such DSLs. Throughout the project, two DSLs were developed: WebDSL, a language for rapid web application development, and mobl, a DSL for mobile application development. Using these two case studies, the dissertation explores the design space, as well as techniques developed to implement the compiler and IDE for such DSLs. The general design principle applied is syntactic integration and separation of concerns. Rather than using a number of DSLs to build a single application, our approach is to develop a single, integrated DSL that can be used to develop the entire application, while still enabling clear separation of concerns. The result of this integration is static verification -- the ability to instantly be notified when your program is inconsistent, without having to run it. The dissertation covers five aspects of DSL design and implementation: (1) Verification, the ability to verify applications written using the DSL; (2) Coverage, how to ensure that a DSL enables its user to express what he needs to express; (3) Abstractions, the use as well as the definition of abstractions in a DSL; (4) Code generation, techniques for efficiently generating executable code from a DSL; (5) Portability, the ability to generate code from a DSL that is runnable on multiple platforms.","dsl; programming; web development; mobile development; design","en","doctoral thesis","","","","","","","","2012-01-11","Electrical Engineering, Mathematics and Computer Science","Software Technology","","","",""

It contains the results of a EuroSDR (European Spatial Data Research) project ‘Atlas of INSPIRE implementation methods’. Aim of the project was to make an inventory of experiences when implementing INSPIRE, in order to share exemplary practices and solutions among national mapping agencies and national INSPIRE contact points. This inventory formed the basis for the generation of the prototype Atlas for all national mapping agencies, policy makers and other stakeholders who have to implement INSPIRE. For SDI research the Atlas provides empirical base material for the conceptualization of SDI implementation approaches. The analytical framework to look at INSPIRE implementation drew on two theoretical notions of how implementation actions can lead to information infrastructure development: a cultivation approach and a design approach. A qualitative data collection process, through a survey and two workshops, tested the extent to which either of the two approaches were prevalent for the INSPIRE implementation. The survey and the workshops provided primary data on INSPIRE implementation experiences of representatives from twelve European countries (Belgium, Bulgaria, Croatia, Cyprus, France, Germany, Netherlands, Poland Slovakia, Sweden, Switzerland, United Kingdom). Comparing the national experiences showed that both types of approaches of INSPIRE implementation are present the EU countries. The cultivation approach is more prevalent in countries which established SDI organizational structures outside the NMAs, and the design approach is more prevalent in countries relying solely on NMAs for INSPIRE implementation. Embedding INSPIRE implementation in national SDI activities seems furthermore to relate to cultivation approaches, consisting of a gradually flatter inter-organizational working relations, and a scaling up strategy which iteratively links the (supra)national implementation plans of INSPIRE to the local implementation plans in national and sub national organizations, and vice versa. The variety in approaches imply that a uniform, best practice, INSPIRE implementation approach for all countries does exist, but that the choices for certain practices strongly relate to the local contextual conditions and windows of opportunities. The implication of these findings for research in SDI development is that more emphasis should be placed on the mechanism of interaction between the slowly changing socio-organizational context and rapidly technologies.","INSPIRE; SDI; information infrastructure theory; cultivation; design","en","journal article","European Commission Joint Research Centre","","","","","","","","OTB Research Institute for the Built Environment","Built Environment","","","",""

(promotor); Desmet, P.M.A. (promotor)","2011","This thesis investigated the measurement of emotion during short episodes of interaction between products and their users. Chapter 2 is a review of the many ways that have been used to measure emotions, organized according to the component of emotion involved: feelings, bodily changes, and facial expression. Measurement based on bodily changes and facial expression is costly and requires extensive expertise. Still, several physiological measures have been considered in the design-related literature but they often lack specificity. Even if automatic recognition systems have recently become available, applied research based on the observation of facial expression remains extremely rare. Both physiological recording and facial expression recognition could in principle have huge advantages for moment-to-moment assessment of emotion as they provide nearly continuous data without requiring the active participation of the research participants. However, their lack of reliability forces researchers to rely on multiple trials and averaging in analysis, thus precluding simple online measurement. Self-report, based on conscious feelings, is easier to apply and is the most common way to measure emotions. Self-report measurement instruments based on different models of emotion are available including measures of pleasantness and arousal and measures of discrete emotions like anger or disgust. Several of these questionnaires have been used in a design context, often to assess responses to product appearance or long-term use. Moment-to-moment self-report is also common in fields like advertisement or music research but is typically limited to dimensional models of emotion (measuring pleasantness or arousal). Chapter 3 is devoted to punctual measures of emotion in person-product interaction. It describes two studies in which participants had to complete different questionnaires right after using a product. The first study compared two questionnaires chosen for their extensive coverage of positive emotions – PrEmo and the Geneva Emotion Wheel – in a test with a coffee machine and an alarm clock. The results show both instruments to be sensitive to differences between products and document a decent level of convergence between the questionnaires. The second study extended these results to a between-subject experimental design in which each participant only used one of the products tested. It found a variant of PrEmo to be sensitive to differences between several personal navigation devices and examined the relationships between measures of different aspects of user experience (perceived usability, meaning, feelings). Chapter 4 is devoted to continuous or moment-to-moment measures of emotion in person-product interaction. It describes the particular challenges facing researchers interested in the dynamics of ongoing emotional changes during the interaction itself. It then sketches an approach developed to tackle this problem, by combining several techniques used in other fields. A key element of this approach is a technique called self-confrontation. It uses video to collect time-bound data about specific events right after the interaction while avoiding interrupting as it unfolds. Chapter 5 describes two studies conducted with the approach developed in chapter 4. The first study asked participants to report about their experience using two vases, selected to be either frustrating or surprising. The second study collected data about the pleasantness or unpleasantness of a drive using one of several personal navigation devices. The differences between the products were found to be related to specific parts of the routes the participants had to follow. The results also suggest that the peak experience (how bad the experience was at its worse or how good it was at its best) is more important in determining the overall experience than the average experience over the whole test. Chapter 6 describes the development of a device, the emotion slider, conceived to make moment-to-moment self-report more intuitive following the principles of tangible design. An experiment using pictures as affective stimuli was conducted before using the emotion slider to collect moment-to-moment data about dynamic stimuli. Following some unexpected results, a series of experiments was organized to better understand the properties of the slider. These experiments showed that the link between movement and affect is more complex than initially thought. Chapter 7 discusses reliability and its impact for applied measurement. It starts with a brief review of key concepts and of the limitations of some common measures of reliability. A numerical example shows that these measures can be misleading when improperly applied to data about transient states like product-related emotions as opposed to individual traits like personality and intelligence. Generalizability theory, a technique that can be used to deal with these issues is introduced through a re-analysis of some the data from chapter 3. Chapter 8 is devoted to the notion of measurement validity. After a review of the most salient perspectives on validity within psychometrics, the data presented in chapters 3 and 5 are re-evaluated. The chapter also contains a discussion of several conceptual issues regarding the validity of measures derived from different components of emotion.","emotion; measurement; design; user experience","en","doctoral thesis","","","","","","","","","Industrial Design Engineering","Industrial Design","","","",""

(promotor); Oppermann, R. (promotor)","2011","Designing computing systems for frontline firefighting is an open challenge. As of today, little computing support exists for such hazardous environments and designers struggle to build appropriate systems that fit the complex configuration on the frontline. Following Christopher Alexander’s understanding, design is about producing living transformations of existing configurations, it requires a thorough understanding of the situation on-site. Alexander introduces pattern languages as a means to describe existing configurations and to make them accessible for design, to link ethnography and design. This thesis therefore develops a pattern language of firefighters’ activities at the frontline to transform the existing practice into a design space for computing support. Grounded theory, as a qualitative method to identify patterns in empirical data, and action research, as a framework that allows studying the interaction between new technologies and existing practice, solidify the methodology of pattern research and are applied to conduct and analyze workshops with French and German firefighters at professional training facilities. Workshops comprise the observation of existing practice, the active participation in firefighting exercises and the introduction of novel artifacts. Linked up as a pattern language, 16 patterns describe the configuration of frontline firefighting. The patterns detail how firefighters organize the division of roles and tasks, how they deal with information in a dynamic environment, how they form a social binding, improvise, provide safety and prepare their work. While similar individual patterns have been described for firefighting and other high reliability professions, the pattern language, beyond these aspects, provides an integrated perspective on the frontline work; it allows developers to reflect technological concepts and supports the participatory design process of ubiquitous computing systems.","design; ethnography; firefighting; ubiquitous computing; pattern language; pattern research","en","doctoral thesis","Shaker Verlag, Aachen","","","","","","","2011-11-29","Industrial Design Engineering","Industrial Design","","","",""

These problems cannot be solved using classical methods on the base of our current utilization of the reflection properties of various objects and their environment. Radar features that may assist in solving these problems are sought in Doppler-polarimetry. Doppler-polarimetric agile radar is able to transmit and receive simultaneously two orthogonal in-polarization signals with waveforms orthogonal in-time, providing the possibility for simultaneous measurements of all elements of the polarization backscattering matrix (BSM) and their Doppler characteristics. Such type of the radar has been developed at Delft University of Technology during this thesis project. Based on long-term Delft experience in linear frequency modulation (LFM) radar, this thesis gives major attention to LFM polarimetric agile radar. However, all major design and validation aspects presented are also useful for any other type of modulation (e.g. phase coded modulation and orthogonal frequency-division multiplexing), despite supplementary investigations on modulation-dependent system characteristics and performance may be needed. Actually two radar systems have been built up. One is in hardware to be used as an experimental research platform for acquiring polarimetric agile radar data, for supporting the verification of theoretical models and the development of signal processing algorithms using different waveforms. The other one is in software simulation environment to be used as a simulation platform not only for system-level evaluation of radar specs, but also for detailed radar design and analyses. Cross-validation of the whole radar system between simulations and measurements has been achieved. The presented design approach may benefit the whole life-cycle of each complex radar system, starting from the very beginning of the design phase up to the very end of the maintenance phase.","polarimetric agile radar; dual-channel transmitter; dual-channel receiver; design; simulation; validation","en","doctoral thesis","","","","","","","","","Electrical Engineering, Mathematics and Computer Science","Telecommunications","","","",""

In this paper, the use of a shell structure made from Nylon 6/6 is studied. Nylon was chosen because of its good mechanical properties and low mass density which is of great importance. Also due to the low aspect ratio, the shell structure is used without any kind of ribs or spars to let the user put the instruments easily inside the structure which facilitates assembly and maintenance. Then the aerodynamic forces are calculated by CFD, Fluent, at Reynolds number 300000 at 5 AOA in a laminar flow. Afterwards the nodal results of Fluent after a nodal interpolation by MATLAB are imported in ANSYS for a full transient analysis. The model in ANSYS is a simple thin shell structure with low aspect ratio, AR=2, with 0.29 mm thickness and volume of 37.2 cubic centimeters, which is calculated in SOLIDWORKS. Finally Nylon 6/6 is modeled as a nonlinear visco-elastic material and the model is assumed to have large deformations, and the constitutive model is based on the Prony series, which consists of 5 Maxwell elements parallel to a spring. The dynamic bulk and shear modulus are then defined in ANSYS. Finally, the weight of structure is reduced to 42.40 grams, for the half of aircraft which is equal to about 16.74% of the whole aircrafts weight.

(promotor); Vambersky, J.N.J.A. (promotor)","2011","During the design and engineering process of buildings and structures an enormous amount of data and information is produced. Logic, knowledge and experience is employed during this process by the designers and engineers to finally come to the design result. Because this information can not be fully recorded by software, a huge amount of information and a potential resource for further investigation in the design process is lost. One reason among others being that the current systems are not able to support the subprocesses in the design process and hold the information stack consisting of data, information, knowledge, etc. If a computational infrastructure would be available which would be able to hold and record the stack produced, an important opportunity exists for learning from this information and producing better designs,manage buildings better, etc. Furthermore, advanced computational technology has a number of additional advantages which at the moment cannot be fully benefited from, such as better coordinated and more optimised design, more understanding of complex behaviour, information management and digital manufacturing. This is because the current life cycle of the building or structure cannot be completely followed through in computational systems and therefore gaps in the essential steps of the design and engineering process appear and therefore loss of information. Again, an infrastructure which would be able to support development of tools, applications, frameworks and systems and which would be able to carry data across processes and tools potentially could improve this situation. This research project envisions this infrastructure as a conceptual base for development of the tools and systems of the future. The term ‘infrastructure’ has been chosen due to the aimed similarity with other infrastructures which acted as a platform technology for a variety of innovations, such as the mobile network infrastructure and glass-fibre network infrastructure. When developing such an infrastructure an important barrier arises which is the fact that it is not trivial to define what the users (designers and engineers) require from such an infrastructure to be able to work closely with it during the design process. An computational and conceptual infrastructure is a very abstract concept for end-users. End-users often are not aware of all technological possibilities and usually can only define immediate short term requirements but not long term development requirements or map out complex abstract concepts. To resolve this issue application of a custom methodology has been proposed and used for the studies in which conceptshave been derived from observations in practice through a process called Empathic Design (Leonard and Rayport, 1997) (note that observations include any data derived observing practice, so also include active derivation of observations, such as discussions, or even observed critique of available systems and paradigms active in practice) and are linked to technological concepts which have been derived from various technological sources of development. Finally, this results in a first step toward a computational design theory which sets out the conceptual direction for development and future research. The process of abstraction of theory from observations through concepts and conceptualisation has been based on the research methodology Grounded Theory (Glaser and Strauss, 1967). To develop the theory a study has been performed into structural design and engineering, its key values and its key characteristics in relationship to their pitfalls for computation. Furthermore, technological concepts have been studied and reported on in this dissertation which provide inspiration and direction to be linked to the concepts from the design and engineering domain. A number of existing technologies has been studied to identify strengths and shortcomings to establish further reaching concepts. The first attempt to meet the requirements established in the computational design theory was made by making use of parametric and associative design, which appears in software applications such as GenerativeComponents (Aish, 2005) and Grasshopper (McNeel, 2008). This paradigm has a various features closely matching the concepts of design, such as the ability to follow through change, the ability to define and process logic and decomposition. However, closer study showed that modifications and extensions had to be made to make it applicable in structural design and engineering. These modifications and extensions are discussed in this dissertation and various published papers. However, finally, a set of concepts remained which required fundamental modification of the paradigm. Therefore, a new infrastructure has been proposed under the name ‘NetworkedDesign’ which includes new concepts unavailable in previous studied paradigms, such as multi-directionality, solving by choice, meta-process and meta-knowledge, as well as a large number of previously existing concepts in a novel combination of a single infrastructure. A first implementation of this infrastructure in the form of a prototype demonstration design system has been used to demonstrate the concepts of the infrastructure in a variety of situations. This infrastructure opens new opportunities for the application of computation in practice as well as new areas of research previously largely unrelated to the building industry such as collective intelligence, computational intelligence and embedded design intelligence. In the practice of the application of computation in structural design and engineering this infrastructure will open new opportunities for new design tools, such as StructuralComponents (Rolvink et al., 2010), as well as partial resolution of the issues with interoperability.","computational design; design; NetworkedDesign; structural engineering; structural design; IT; ICT; ICKT","en","doctoral thesis","VSSD","","","","","","","","Civil Engineering and Geosciences","BEMNext Laboratory","","","",""

In turn, the aim of this theoretical paper is to advance environmental sustainability as part of managing the four primary businesses. The sustainability of construction-related business management is enabled by implanting drivers into each of the eight competitive arenas. In life-cycle contracting and development businesses, the novel drivers include the coupling of object development ideas with sustainability advantages. In design-build contracting businesses, such drivers include the re-engineering of value chains with all tiers of designers, subcontractors, and suppliers. In design businesses, such drivers include the transformations of design firms into long viewers, path dependency breakers, stock-specific programmers, object-specific planners, impact blockers, and impact cause tracers. In supply businesses, such drivers include the adoptions of cradle-to-cradle certifications, product formula renewals, and full responsibility takings over the life-cycles of supplied units. In the future, practitioners and researchers alike could adopt this high-sustainability 8-arena framework.","building products; business management; constrcution; design; sustainability","en","conference paper","","","","","","","","","","","","","",""

As innovative knowledge workers and system integrators architects are often called upon to produce innovative and custom designed buildings. Architects can be characterized as knowledge intensive professionals who help to lead innovation. However, most of the research conducted in design innovation and organisational paradoxes has had a product portfolio focus. For example, it has been claimed that product innovation relies on two seemingly contradictory and paradoxical processes in product development organisations: the exploitative and the exploratory. How might these concepts be related to architectural firms and design teams? Using the above concepts an initial model was developed and then tested in order to understand the paradoxical processes that architects employ when designing. How might design processes in service firms differ from either linear or dichotomous models of innovation with their origins in product development? An initial model is proposed which is then tested and refined. These questions are tested in a broader survey of 73 Australian architectural practices. The survey aimed to identify the links between exploitative and exploratory design processes in the firms and the organisational paradoxes which surround these. A survey framework was developed which defined and highlighted to what degree architects instigate Radical or Incremental design changes in projects. The survey identified the extent to which Australian architects generate new design solutions after a particular design has been mandated. It concludes that these architects deliberately sought to foster highly paradoxical processes within their firms in the early stages of a project in order to create new design knowledge. Highly paradoxical processes, which oppose exploitative and exploratory design activities, tend to diminish as the project proceeds. Further research is needed to clarify if design processes with a high degree of paradox are where project innovation occurs. The paper concludes by outlining a model of exploitative and exploratory innovation and organisational paradox in knowledge intensive design firms.","architecture; design; organizational paradoxes; innovation","en","conference paper","","","","","","","","","","","","","",""

(promotor); Mulder, J.A. (promotor)","2011","Kites have seen substantial development in the last 10 years, going from mostly toys to high-performance sports-related equipment for e.g. kite surfing. The design process of these kites, however, is mostly a trial-and-error affair. Ten years after the sports-related kite revolution a new development is is emerging: Industrial applications for kites. Systems to propel ships and generate sustainable energy are now under development worldwide at over 40 companies and institutes. These new industrial applications will put strickter and more complex requirements on these kites. The current trial-and-error approach to the design of kites will not suffice. In this thesis a different design methodology is proposed. This methodology leans on three pillars. The first pillar is ""Knowledge"". As it turns out, there is still a lot unknown about the behavior of kites. This thesis further develops that knowledge. The seccond pillar is ""Simulation"". Nowadays, a large number of prototypes are produced and tested. So many in fact, that many designers do not even have the time to test them all. With the advance of complex industrial kites, this situation is expected to escalate. The capability of virtually testing kites will shrink the prototype phase into more managable proportions. Furthermore, it will contribute to the understanding of kites as well. This thesis proposes a number of models to simulate kites on a conventional desktop computer. These models include both rigid-body and multi-body models. The latter is capable of simulating a kite including its extreme flexibility. The third and last pillar is ""Measurement"". Controlled and reproducable measurements are essential for validation and evaluation. The thesis closes with a number of case studies which show the advantages and opportunities of this methodology.","kite; multi-body dynamics; laddermill; sustainable; design; flexible","en","doctoral thesis","Uitgeverij BOXPress, Oisterwijk","","","","","","","","Aerospace Engineering","ASSET","","","",""

Whether it's a minor surgery or major intervention with either modest ambitions or big ones, these interventions have something in common and it is that they should be managed from conception to realisation. As the title of this book suggests Management of Urban Development Processes in the Netherlands is about the entire process of managing urban development and covers the full life-cycle of urban areas. Secondarily, the book elaborates on the Dutch approach. The focus is not on comparing Dutch urban area development with the practice in other countries. Nor is it our aim to position Dutch urban area development in an international framework. What the book does aim to do is provide an understanding of current practice and an overview of acquired knowledge and instruments developed in the Netherlands.

Inspired by existing approaches to the experience of love from social psychology, research tools are developed for the closer study of person-product love. Using those tools the research in this thesis investigates how person-product interactions are linked to the experience of love and how these influence love over time. The findings reveal how the experience of love arises from person-product relationships, how love relationships develop over time, and which factors can provoke change in the love experience and love relationships over time. These findings present opportunities for design researchers and designers to foster rewarding experiences and long-lasting person-product relationships.

As such it introduces the notions of responsibility, issues and stakeholders to other drivers for design such as new technology, brand awareness and profitability. The concepts of needs/issues, both environmental and social/cultural, strategies and assessment in relation to evolving a sustainable world are discussed with students in open forums. There is a shift in delivery whereby students are encouraged to design the experience or response to need rather than assume design propositions have to be products. In effect the mandate for product design has expanded to encompass services and systems. Importance is placed on research identifying real rather than assumed needs and students are taught to think holistically beyond the lifecycle of products. The financial concept of the single bottom line is expanded to the triple bottom with happiness and well being examples of the parameters used to gauge the success of design propositions.

However, there is still little understanding on how to, in practice, best bring environmental considerations into this part of the innovation process. There are two central questions considered in this paper: are companies integrating environmental considerations into the FFE activities and if yes, how? In this paper we illustrate the current FFE practices from the perspective of environmental considerations. The paper is based on in-depth interviews with eight multinational companies, based in Europe. The interviews reveal that most companies do have experience with considering the environmental requirements in the FFE, but there are significant differences in the “green” FFE practices in terms of frequency, structure and the role the environmental requirements play in the activities of the FFE.

They are at the cradle of new technological developments and can thereby influence the possible risks and benefits more directly than anybody else. I have argued elsewhere that emotions are an indispensable source of ethical insight into ethical aspects of risk. In this paper I will argue that this means that engineers should also include emotional reflection into their work.

The Challenge of Incorporating Moral Values into Design","Manders-Huits, N.L.J.L.","","2010","Recently, there is increased attention to the integration of moral values into the conception, design, and development of emerging IT. The most reviewed approach for this purpose in ethics and technology so far is Value-Sensitive Design (VSD). This article considers VSD as the prime candidate for implementing normative considerations into design. Its methodology is considered from a conceptual, analytical, normative perspective. The focus here is on the suitability of VSD for integrating moral values into the design of technologies in a way that joins in with an analytical perspective on ethics of technology. Despite its promising character, it turns out that VSD falls short in several respects: (1) VSD does not have a clear methodology for identifying stakeholders, (2) the integration of empirical methods with conceptual research within the methodology of VSD is obscure, (3) VSD runs the risk of committing the naturalistic fallacy when using empirical knowledge for implementing values in design, (4) the concept of values, as well as their realization, is left undetermined and (5) VSD lacks a complimentary or explicit ethical theory for dealing with value trade-offs. For the normative evaluation of a technology, I claim that an explicit and justified ethical starting point or principle is required. Moreover, explicit attention should be given to the value aims and assumptions of a particular design. The criteria of adequacy for such an approach or methodology follow from the evaluation of VSD as the prime candidate for implementing moral values in design.","applied ethics; technology; ethics of technology; methodology; values; design; value-sensitive design; value-conscious design; awareness","en","journal article","Springer","","","","","","","","Technology, Policy and Management","Values and Technology","","","",""

In order to achieve the final shape, several electrodes have to be made by milling with different levels of geometrical accuracy. Besides, the material removal rate of EDM is relatively low. This results in a long throughput-time and high manufacturing cost. Therefore, industries are looking for alternative technologies to overcome these drawbacks; micromilling is one of the promising technologies. The advantages of the micromilling technology include the applicability of a broad range of materials including hardened tool steels, the capability of manufacturing three dimensional geometries, accurate machining of complex features, and it is economical for small and medium lot sizes, etc. However, although micromilling in principle is a good alternative for the EDM process, it is found in research that some challenges have to be overcome before this technology is ready to be adopted in industrial applications. The literature survey shows that the fundamental micro cutting mechanism has been well investigated and understood through the study of micro orthogonal cutting and ultraprecision machining. Issues related to the application of micromilling have however not yet been well studied. Besides, inconsistent observations are commonly seen in literature. This is because observed results in micromilling are highly dependent on the experimental conditions. Based on the literature survey and initial micromilling tests, the general goal of this research has been defined as to develop and describe a reliable micromilling process for precision machining of hardened tool steels. It was decided to first improve lives of micro endmills to achieve a reliable cutting, and then to improve the performance of the process through process planning. In this research, experiments were mainly done with Ø 0.5 mm square endmills on hardened tool steels (AISI H11, H13, etc.). Experimental investigations were done to identify the main problems in micromilling. It was observed that the used commercial micro tools suffered severe wear, the tool life was too short to conduct a successful task, and the workpiece quality was not achieving the requirements. Investigations were conducted to understand tool wear types and mechanism. The factors which influence the tool performance were analyzed. It was found that the geometry of commercial tools is mainly derived from macro endmills, with which the cutting edge corners have the highest stress level. The machining parameters and tool paths are two factors that have significant effect on the tool performance; however, there was no good method available for the planning of the micromilling process. The geometry of micro endmills was studied theoretically by means of analytical modeling and FEA method. Having understood the relationship between geometrical features of the cutting tool and their influence on the tool performance (stiffness and strength of the cutting edge corners), the geometry of the micro endmill can be designed specifically for a given application to achieve the desired performance. This method was demonstrated by designing the micro square endmill especially for hard milling applications. The newly designed tools were manufactured and validated through experiments in comparison with the commercial tools. The experimental results have shown that the new designs have improved the tool performance as expected. The planning of the micromilling process has been divided into two parts. In the first part, design of experiments has been used to understand the relationship between input variables (machining parameters and tool paths) and process response (tool wear and surface finish). With this method, the significant variables can be identified by means of ANOVA analysis, and the cutting conditions can be planned accordingly to optimize the process output. For example, to have a long tool life is important for the roughing operation, and to achieve a good surface finish is of interest for the finishing operation. In the second part of the process planning, a knowledge-based method is used to plan cutting conditions for the machining of micro features with high aspect ratios. The selection of machining parameters was done by means of a force model, which describes the relation between machining parameters and average forces. The tool paths were tested by a FEM model. An improved tool path was proposed to overcome the disadvantage of the conventional tool path. Experiments were done with conditions chosen by the theoretical analysis, and the results proved the validity of the developed method. Micro ribs with aspect ratios higher than 50 could be machined successfully.","micromachining; micromilling; design; experimentation; modelling","en","doctoral thesis","","","","","","","","2009-10-22","Mechanical, Maritime and Materials Engineering","Precision and Microsystems Engineering","","","",""

I will explain that this approach assigns a central place to human capabilities in our discussions of justice and development and criticizes a focus on utility or preference satisfaction. In the literature on the capability approach technical artifacts have hardly been acknowledged as an input for human capabilities, although Sen and some other authors sometimes refer to the example of a bicycle that expand one’s capabilities to move about. Using Bijker’s analysis of the history of the development of the bicycle, I argue that the details of design are very important for an artifact’s impact on human capabilities. In current design practice the focus is, however, too much on things like usability and user satisfaction. Where Buchanan has argued that design should rather find its ultimate ground in human rights and human dignity, I propose human capabilities as an alternative. Due to the functionalistic orientation of the capability approach, this alternative may be more fruitful and appealing to for designers. Analogue to ‘value sensitive design’ – an emerging approach in the ethics of technology - we should thus look into the possibility of ‘capability sensitive design’. What this entails exactly should be investigated, but it is likely that it will turn out to have commonalities with existing design movements like participatory design and universal design. The article will end with some suggestions for further research on a capability approach of design.","capability approach; design; development; poverty; human capabilities; technology; Martha Nussbaum; Amartya Sen; technical artefacts","en","journal article","MIT Press","","","","","","","","Technology, Policy and Management","Values, Technology & Innovation","","","",""

By building upon the similarities and differences of the two dominant perspectives, this paper then goes on to show that the modeling and intervention possibilities in both perspectives differ to a great extent. The emerging systems-of-systems discipline generally calls for an ldquointegrationrdquo of both perspectives in order to model and design these complex sociotechnical systems, but in this paper, it is argued and shown that full integration is not the preferred way to go. Instead, the emerging discipline should strive to facilitate the use of both perspectives alongside each other in a sensible way and, thereby, not discard the strengths of either perspective.","actor networks; complex systems; design; engineering systems; systems engineering; systems of systems","en","journal article","IEEE","","","","","","","","Technology, Policy and Management","Multi Actor Systems","","","",""

From an economic point of view, the design of the lining, i.e. the thickness and reinforcement of it, would be optimal if the loading during construction is less critical than the loading during service life, i.e. to the overburden loading. If necessary one could take measures to prevent that any loading during construction becomes more critical than the overburden loading. If this can be achieved, the structural design would be limited to establishing the overburden pressures, and calculating equilibrium between lining strength and overburden. For optimisation one could use Probabilistic theory and Risk Analytic techniques to establish a sufficient distance between actual loading and design parameters to get the most economic lining thickness and reinforcement. In order to evaluate our present situation with respect to lining design, some observations from engineering practice are iscussed: the first, from the construction of the 2nd Heinenoord tunnel, where the damage to the lining during construction was above average; the second from the construction of the Green Hart tunnel where measurements show, that flexibility of the tube and the influence of interaction between structure and underground can also lead to critical loading conditions for the lining.

They attempt to give users a voice or a role in their projects, with the intention of developing products that match users' needs and preferences. This approach is especially interesting in the information and communication technology (ICT) industry, in which many innovations are driven by development of technologies. The author works in HCD projects in the ICT industry and studied one particular project as a participant observer. In this project, two telecom applications were designed together with and for two groups of users: police officers and people who provide informal care. The resulting case studies are interpreted, drawing from the fields of design studies and science and technology studies, and using texts of the philosophers Levinas and Derrida. HCD is presented as a process that happens between people and as a process with ethical qualities. The case studies demonstrate that HCD is a worthwhile approach. They also show the difficulties of cooperating with users and of multi-disciplinary team-work. HCD practitioners attempt to be open towards others, but they also tend to move towards closure and towards the self. The author suggests reflexive practice as a way for practitioners to be more aware of and to articulate these tendencies. This is intended to help them to better align their practices with what HCD can be about: a process of learning and creating together.","design; innovation; human-centred design; telecom; police; informal care; science and technology studies; organization studies; ethics; Levinas; Derrida","en","doctoral thesis","IOS Press","","","","","","","","Industrial Design Engineering","","","","",""

Such evaluations are usually conducted in simple single-shot studies where consumers only once have to evaluate, for instance, the attractiveness of a design. However, innovative designs often break common visual habits by combining more or less familiar parts into a new concept (Carbon and Leder in Appl Cogn Psychol 19:587–601, 2005). Thus, when design innovation is realized in a too advanced way, such designs are expected to be rejected by perceivers at first glance due to low familiarity. However, from everyday experience, we know that consumers’ liking of products often is a dynamic process, which cannot be captured by simple single-shot studies. Carbon and Leder (Appl Cogn Psychol 19:587–601, 2005) have proposed the repeated evaluation technique (RET) for measuring such dynamic effects, which we have combined here with the measurement of electrodermal activity (EDA). The EDA data demonstrated that the RET captured dynamic effects, as the EDA showed specific sensitivity for highly innovative material only after the RET had been conducted; a cross-check with the same material analyzing item-specific boredom revealed that participants were much more bored by low innovative material over time than by highly innovative material. Thus RET seems to be a valuable tool for relevant affordances of design evaluation, particularly when innovative designs have to be evaluated.","design; styling; prediction; innovation; electrodermal activity; adaptation; attractiveness; preference; applied cognition; innovativeness; repeated evaluation technique; mere exposure","en","journal article","Springer","","","","","","","","Industrial Design Engineering","Product Innovation Managment","","","",""

For this reason a first version of physical hydrological scale model was designed and built. The goal will be to build a second version which it is possible to move to be used for practical lectures and for demonstrating in lectures of the first year of bachelor. The objective of the scale model is firstly to show the basic concepts of rainfall-runoff like time of concentration and to show that rainfall duration, slope and infiltration influence the shape of the hydrograph. The other aspect is to show the separation between the overland flow and the groundwater flow to see the delay between the both and the different contribution of the both in a river. Moreover, such a scale model can show basic model of rainfall-runoff relationships like rational method or unit hydrograph method or reservoir method. To realize such a scale model, the first issue was to find proper materials to show concepts that happen in real scale in days in a few minutes. The second part was to check by experiments the set-up and to discuss about results. With this first version of the scale model, it is possible to show more than basic concept like time of concentration; it could be used for practical lectures to calibrate a reservoir model for example. Another experiment could be done, with metal valve (and not plastic valve). It will be possible to show that storms that move upstream tend to produce lower peaks of a longer duration than storms that move downstream. The second version with a pressure regulator will increase the possibility of the scale model. It will become a real complex scale model with the possibility to adjust rainfall intensity, rainfall duration, slope, rainfall distribution and effect of the direction of storm movement.","rainfall-runoff; runoff; scale model; design; hydrological; internship report","en","report","TU Delft","","","","","","","","","","","","",""

The Flat City model proposes that the environment is structured into strata of ‘place-regions’, each with their own definitive scales and each with their own connective matrix enabling the ‘regional’ movement which realizes places. A detailed empirical study of spatial centrality as revealed by the distribution of street-edge commercial functions in the metropolitan territory around Amsterdam, is presented and evaluated in the terms of this model in another paper (Bruyns and Read, 2007). The results of this research suggest that actual physical urbanization or the emergence of settlement form, does not simply follow connectivity, but depends very often for the precise location and character of its emergence, on a factor of ‘grounding’ within place-region strata at lower scale-levels. This implies immediately a critique of current connectivity-led urban development practices in the Netherlands and a brief critique is developed here in relation to two recent urban development plans. The results also begin to suggest a different mechanism of the transfer of economic and social potential from networks to urban place. This mechanism of transfer has been broadly understood in terms of technologies of connectivity and their simple imbuing of pre-existing places with higher-scaled potentiality – and, for example, Saskia Sassen evaluates a number of global city places in terms of ‘connectivity indices’ (Sassen, 2006). Our results suggest a strong interdependence between matrices of connectivity at different scale levels, and that the potentials of connectivity emerge out of scaled layers of connectivity considered right down to the matrices of the street grid of the urban fabric. But this also means we can develop a clearer understanding of the relationship between the global, the metropolitan and the local. These terms do not imply any dualistic opposition, as in global-local – rather the properties of the global and the metropolitan become incorporated in the local in a capture of the potentials of larger ‘worlds’ within smaller, and a realization or materialization of these potentials in the smaller. This implies a monadology of, for example, Leibnitz or Whitehead, more than a straightforward network spatiality of connectivity. This paper will continue to develop this notion as a possible way to understand urban spatialities, by suggesting possible ways of understanding the potentialities of real local fabrics as ‘worlds of incorporation’.","urban morphology; movement layers; Amsterdam region; infrastructure; design","en","conference paper","","","","","","","","","Architecture and The Built Environment","Urbanism","","","",""

Intermediaries are a particularly interesting application domain: on the one hand, they are given opportunities by electronic business to reinvent their value logic, while on the other they are threatened by opportunities for customers and suppliers to deploy electronic business to do business directly. Designing for Acceptance addresses the acceptance of electronic intermediaries by studying the design of the exchange. For example, should a web catalogue provide price information and should it consider an extension with transaction functionality? Developing the right exchange design is a complex undertaking because of the many design options and the interests of multiple actors that need to be taken into account. Four cases were studied: Tapestria (interior fabrics), SeaQuipment (maritime products), Meetingpoint (insurances) and Voogd & Voogd (insurances). The results are an exchange design model and patterns that are derived from numerous case lessons and are supported by insights from theories on electronic intermediaries, acceptance and business design. The exchange design model offers a systematic insight into generic exchange design themes that are relevant to the interests of customers, intermediary and suppliers.

This study contributes to current knowledge by providing support for balancing interests in exchange design beyond simple prescriptions like ""creating win-win situations"".

To reduce the heavy workload, washing machines were invented about 100 years ago. 50 years of innovations led to a reduction in water, energy and detergent consumption and the interface became easier to use. However, the overall usage of the machine is still the same. After a first literature exploration of the subject it became clear that there is hardly any scientific research. Innovations are minimal as well. In fact, the design of washing machines looks almost the same as some 50 years ago - a white box with an opening height of 60 cm above the floor. The main reason for starting this study was that Siemens Household Appliances wanted to find out whether their consumers would appreciate an innovative washing concept and whether it was worth it to develop a new washing machine. As there seems to be a need for innovation, this thesis aims to answer the following questions: 1) Does the opening height influence movements and body postures while loading and unloading a washing machine? 2) Are body postures and anthropometric data, age or gender correlate? 3) Do physical stress or comfort problems occur? 4) Is there a relationship between comfort and typical body postures when un-/loading a washing machine? 5) Are there relationships between subjective comfort and anthropometric data, age or gender? 6) Based on these results, can a washing machine be innovated and would it be successful in other cultures as well?

(promotor); van Kuik, G.A.M. (promotor)","2006","To meet growing energy demands, the Kyoto protocol and the much desired diversification of supply, wind energy has become a mainstream source of energy in the EU. Cost wise it is already competing with gas fired electricity. In the last decade wind moved offshore to accommodate even more wind power. The offshore wind resource is more abundant and of a better quality, resulting in higher electricity output. On the other hand, the cost of installing turbines offshore is higher than onshore. To improve the cost-effectiveness of offshore wind, the risks involved must be known and mitigated and the critical design parameters must be optimised. From an engineering point of view, these requirements can be met through the following steps: - understand the basics of offshore wind turbines - apply lessons learned from previous projects - improve design tools. This thesis focuses on the design of the support structure. First, the basics of offshore engineering and of wind energy technology are summarized, specifically focused on the support structure design. Then, an overview is given of four actual offshore wind farm designs and their details. The design methods were compared mutually and with a design of a typical offshore oil platform. For most of the design steps, the methodology is consistent. Only the fatigue damage assessment is done differently for each individual project. Fatigue assessment in offshore engineering is done in the frequency domain. This method can be applied because the wave loads can be effectively linearized. The advantages of the frequency domain method are the clarity of presentation of intermediate results and the final outcome as well as the speed of calculation. The offshore wind industry standard (both onshore and offshore) is to use time domain simulations, which enables taking all non-linearities of the turbine operation into account. A disadvantage of this for the design of support structures is that offshore contractors lack both the aerodynamic knowledge and knowledge of the turbine details to use the full time domain simulation method to calculate the total fatigue damage. In this thesis a frequency domain method is developed to solve this problem. An interface between turbine manufacturer and offshore contractor is created that avoids the need to transfer commercially sensitive turbine details. The offshore contractor can further optimise the support structures with the software packages he normally uses. The frequency domain method is tested for the Blyth offshore wind turbines, for which a validated computer model and on-site measurements were available. Further, the method is applied to a design for the Dutch offshore wind farm to be erected at Egmond in 2006. In both cases, the frequency domain method works very well and gives results that compare well with time domain results. The computer time required to perform a fatigue calculation has been reduced from several hours in the time domain to less than 2 minutes in the frequency domain. This high speed of calculation opens possibilities for parameter variations to check the sensitivity of design choices and for optimisation of every structure within the wind farm. This has the potential to significantly reduce cost and risk. A key issue in the accuracy of the method is the effect of the aerodynamic damping of the operating turbine on support structure dynamics. Several calculation methods for this damping have been tested and have shown to give reasonable results. More work is needed to more accurately pinpoint the magnitude of this aerodynamic damping. The frequency domain method is currently being implemented in the software of an offshore contractor while other companies have already shown interest.","offshore; wind turbines; design; fatigue; frequency domain","en","doctoral thesis","Duwind","","","","","","","","Civil Engineering and Geosciences","","","","",""

The images are used in collages and moodboards to define and communicate the direction of a design project at an early stage of the design process. This thesis describes how designers interact with their collections of visual material and how new tools can support this interaction. During the research two field studies were conducted and several working prototypes were built. During the field studies and from theory it was found that the activity of collecting and organizing is in itself a creative act. Furthermore, in practice the designers were found to keep two separate collections. A physicial collection of snippets, photos and advertisements that are gathered, shared and organized as a collection and another goal-oriented collection of digital images on computers, cd-roms and internet, which are used to find images to be used in collages or moodboards. The final prototype in the research, called Cabinet, is a tool that brings these two collections together, allowing the designers to interact with physical and digital visual material equally and simultaneously. Cabinet does this by providing a physical interaction with digital images using direct manipulation on a large table surface using expressive gestures. Furthermore with Cabinet designers can easily and fluently add physical material to their collections, using a camera that records visual material placed on the table. The working prototype of Cabinet was used as an apparatus in the final field study, in which three designers at three design agencies used Cabinet for a period of four weeks in their regular work practice. During this experiment Cabinet was both evaluated and used as a means to get insights into how designers interact with visual material.","inspiration; tools; interaction; collection; visual material; collecting; organizing; aesthetics; usability; design; industrial design; product design; physical material; prototypes; prototyping; doctoral design","en","doctoral thesis","","","","","","","","","Design, Engineering and Production","","","","",""

(promotor)","2004","Buildings use energy for heating, cooling and lighting, contributing to the problems of exhaustion of fossil fuel supplies and environmental pollution. In order to make buildings more energy-efficient an extensive set of âenergy saving building componentsâ has been developed that contributes to minimizing the energy need of buildings, that helps buildings to access renewable energy sources, and that helps buildings to utilize fossil fuels as efficiently as possible. Examples of such energy saving building components are heat pumps, sunspaces, advanced glazing systems, thermal insulation layers, etc. Building simulation tools appear to be a suitable instrument to support decisions regarding the selection and integration of energy saving building components: they can provide detailed information on the thermal performance of buildings that have not yet been built, thereby allowing objective comparison of different design options under identical conditions. However, in general the actual use of simulation tools to provide information to support the selection of energy saving building components does not live up to this expectation. The development of new building energy simulation tools shows a continuous increase of capabilities and complexity. This trend increases the dependency on adequate modeling and expertise, and thereby increases the barriers to integration of building design process and building simulation even further. Therefore, the central goal of the PhD-project is the development of a strategy to provide computational support during the building design process for rational design decisions regarding the selection of energy saving building components. The strategy is to be substantiated by development of a prototype that demonstrates the feasibility of the strategy. The work presented in this thesis consists of four main research activities, all focusing on the use of simulation tools to support the selection and implementation of energy saving building components: 1) analysis of the design process of current energy-efficient building projects; 2) development of an approach for well-founded selection of these components; 3) analysis of the suitability of existing tools to support the selection process, and development of ideas for improvement of these tools; 4) development of a strategy as well as a proof-of-concept prototype that provides support for the selection of energy saving components and that demonstrates the viability of the proposed changes. Analysis of current energy-efficient building projects The analysis of current energy-efficient building projects was initiated by a lack on unbiased information on the way in which energy saving building components are selected in current practice, and lack on information of the role of simulation tools in this selection process. The goal of the analysis was to find out for recent prestigious building design projects in the Netherlands how this selection took place, and what role tools played in supporting the selection. In order to attain this goal three case-studies and a survey were conducted. The case-studies provided in-depth information on three projects; the survey demonstrated the representative ness of the findings from the case-studies for a larger sample of energy-efficient buildings. The overall findings are that in current projects simulation tools do not play an important role in the selection of energy saving building components, since these tools are used in later phases than those relevant for the selection, and are only used for different purposes (optimization and verification rather than to support choices). Instead, most energy saving building components are selected based on analogy: use of similar components in previous buildings by the architect or consultant, or the use of these components in demonstration projects. It appears that decision-making on energy saving building components is based on simple, heuristic decision rules. Yet it seems preferable to apply multi-criteria decision rules to the selection of these components, ensuring that different requirements are considered in the decision-making process. Hence there is a need to improve both the selection procedure as well as the tools that support that selection. An approach for well-founded selection of energy saving building components The development of an approach for well-founded selection of energy saving building components had as goal to improve the current way of selecting these components. Requirements and constraints for making well-founded choices have been identified and used to assess existing theories for making design decisions. An approach for performance-based selection of energy saving building components has then been developed, using applicable elements from existing theories to define the essential steps: definition of an option space, identification of relevant functions, specification of performance indicators, prediction of performance for all options and all performance indicators, and evaluation followed by selection of the most desirable option. This approach rationalizes the selection procedure, and makes the role of subjective assessment explicit. Since it is based on performance prediction, it provides an optimal base for the use of simulation tools. The viability of this approach has been demonstrated through application of the approach to an example. Analysis and improvement of tools Once the selection procedure had been developed, the next goal was to improve the tools that support this procedure. The analysis and improvement of tools for the selection of energy saving building components consisted of the following steps: analysis of the different main categories of tools (design tools, modeling tools, analysis tools, support environments and others) and their role in supporting the selection of energy saving building components, and assessment of existing tools as well as identification of possibilities for improvement of the two most important categories (analysis tools and support environments). It was found that existing analysis tools are capable of supporting the selection according to the performance-based approach, on condition that enough time and expertise is available for the modeling and simulation work. Support environments are mostly still under development and have not yet gained widespread use. Analysis tools can be improved through reverse-engineering, which clarifies the building design alternatives and performance indicators that can be handled by these tools. Support environments can be improved by embedding analysis tools as well as a selection mechanism that helps users to find a suitable (analysis) tool for any specific (analysis) job. A strategy and prototype for the selection of energy saving components The final goal of the research project was the development of the strategy to provide computational support during the building design process for rational design decisions regarding the selection of energy saving building components, and the realization of a substantiating prototype that shows the viability of this strategy. In order to reach this goal the afore-mentioned ideas on improvement of the process and support tools have been combined. Participation in an international research project, the Design Analysis Interface (DAI) - Initiative, provided the final elements needed for completion of the research. A strategy for selection of energy saving building components has been developed in this thesis that consists of the following elements: 1. Energy saving building components should be selected according to a procedure that consists of definition of an option space, identification of relevant functions, specification of performance indicators, prediction of performance for all options and all performance indicators, evaluation of predicted performance and selection of the most desirable option. 2. Availability of time and expertise for modeling and simulation work are the most important limiting factors that hinder the application of existing building performance simulation tools in support of the selection of energy saving building components. In order to overcome this problem the analysis request must be stated unambiguously. At the same time, building performance simulation tools must be pre-conditioned (reverse-engineered) in order to meet these specific analysis requests. 3. The procedure for the selection of energy saving building components must be assisted by the use of a support environment that provides a mechanism that gives users access to different (embedded) building performance simulation tools for doing specific analysis tasks. A prototype of a Design Analysis Interface (DAI) - Workbench has been developed that demonstrates the feasibility of better integration of building analysis tools and building design process through the use of a layered, process-centric approach, thereby showing the viability of the ideas to provide improved computational support for the selection of energy saving building components. The concept of analysis functions links the analysis process with simulation tools by matching analysis task and tool capabilities. An analysis function gives an exact specification of the performance indicator that is to be generated by the analysis. Of course, full computational support for the selection of energy saving building components can only be achieved once the DAI-Workbench contains a set of analysis functions that covers most relevant performance aspects for buildings with such components, plus qualifying tools and interfaces from analysis functions to those tools. Future work on the integration of building simulation and building design requires further development of support environments that capture and support the analysis process itself, and that provide access to tools that are able to support relevant process steps. Reverse-engineering of simulation tools to match specific analysis tasks seems an important task in order to increase the applicability of these tools.","building; design","en","doctoral thesis","Delft University Press","","","","","","","","Architecture","","","","",""

(promotor)","2003","Over the last years the ever-growing demand for higher performance has led to much interest in using nonlinear circuit concepts for electronic circuit design. For this we have to deal with analysis and synthesis of dynamic nonlinear circuits. This thesis proposes to handle the nonlinear design complexity by dividing the design process in two steps. In the first step, a high-level synthesis/analysis step, a circuit topology implementing the wanted (nonlinear) function is found. We conclude that an expansion in basic functions, chosen to fit the nonlinear building blocks used, appears to be the best option for implementing this step. The second step consists of a low-level analysis/synthesis step, in which the quality of the topology is determined. The thesis research has focused on using the linear time-varying (LTV) small-signal model for describing the dynamic behaviour of nonlinear circuits in the context of low-level analysis/synthesis. This model is a generalization of the conventional linear time-invariant small-signal model and allows the use of equivalent stability criterions. Linear eigenvalues and poles are generalized to dynamic eigenvalues, Floquet exponents and Lyapunov exponents. The LTV small-signal model decreases low-level modeling complexity by using knowledge from the high-level step. The linear time-varying approach was applied to various specific nonlinear circuits: a negative feedback amplifier with class-B output stage, a dynamic translinear filter and oscillator and a differential pair used as a limiter. These design examples show that the linear time-varying approach is a good modeling candidate for low-level synthesis/analysis.","design; nonlinear circuits; linear time-varying approach; dynamic behaviour; dynamic eigenvalues; floquet exponent; lyapunov exponent","en","doctoral thesis","","","","","","","","","Information Technology and Systems","","","","",""

Strict adherence to existing design guidance has resulted in many of these structures being built using multiple layers of different rock sizes, high quality imported rock and carefully prepared foundations. Some innovative structures have, however, used locally available rock with simpler cross-sections placed on unprepared foundations, apparently without significant reduction to the overall erformance of the scheme. This report gives guidance from a short research project which examined practical experience on rock structures firom around the UK, with particularly emphasis on those that depart from conventional design rules. The report demonstrates that there are opportunities for lower cost rock structures for beach control and coast protection. Established design guidance provides a good degree of confidence in predictions of performance o f coastal structures, but it is widely perceived that simple design rules can be overly prescriptive, particularly for nearshore structures in shallow water depths. The opportunities for lower cost structures principally relate to improved assessment of armour size for depth-limited waves, reduction in armour size for closer armour packing, and the need for complex underlayer / filters. The report emphasises the need to understand the performance of individual structures in the context of the overall scheme and ultimately national objectives, which provides an incentive to re-explore the balance between cost and structure performance. It also encourages the consideration of cost issues during the design of rock structures. Although the use of lower cost structures may also provide safety and environmental advantages, the stractures described are envisaged to be of greatest benefit in locations where conventional stractures would not be economically justified.","overtopping; coastal rock; safety; rock structures; protection; erosion; design","en","report","DEFRA / Environment Agency - Flood and Coastal Defence R&D Programme","","","","","","","","","","","","KWP-collection",""

The H. Clarkson database contained in 1994, 834 of these ships, in a dead-weight range of 50.000-76.000 tons. The dimensions of panamax vessels are restricted by the dimensions of the locks of the Panama Canal, especially the beam. Shipowners and shipyards have put a lot of effort into maximising the deadweight of the vessels within these restrictions. The question is: Does the market honour this effort with higher charter rates? In other words: Is there a relation between the design characteristics and the charter market performance? This study has analysed approximately 10.000 of the published fixtures over the period 1989-1994, and related the charter rates to the dsign characteristics of the bulk carriers. This book is important for shipowners, shipbrokers, shipyards, naval architects, financial institutions, classification societies and all others involved in the bulk shipping industry.","bulk carrier charter market; Panamax; design; bulktransportschepen","en","book","Delft University Press","","","","","","","","Delft University of Technology","","","","",""

After the description of governing parameters, the hydraulic response is treated. This is divided into: - Wave run-up and run-down, - Wave overtopping, - Wave transmission, - Wave reflection. The main part of the paper describes the structural response which is divided into: - Rock armour layers, - Armour layers with concrete units, - Low-crested structures, - Berm breakwaters, - Underlayers and filters, - Toe protection, - Breakwater head, - Longshore transport at berm breakwaters. The design tools given in this paper and by Delft Hydraulics' pc-program BREAKWAT are based on tests of schematised structures. Structures in prototype may differ (substantially) from the test-sections. Results, based on these design tools, can therefore only be used in a conceptual design. The confidence bands given for most formulae support the fact that reality may differ from the mean curve. It is advised to perform physical model investigations for detailed design of all important rubble mound structures.","design; rubble mound; breakwaters; classification; BREAKWAT; ICCE 1992","en","report","ICCE 1992 local organising committee","","","","","","","","","","","","ICCE 1992",""

These include the purpose of the structure, the design waves, the design wave climate, the material of which the structure is to be built, foundation conditions, earthquakes, tsunamis, availability of construction and maintenance equipment, availability of funds for maintenance, availability of laboratory and oceanic equipment and vessels, etc. The focus of this lecture today however, will primarily include conceptual and practical factors, including those considered in the Hudson formula for design of rubble mound structures against waves. Firstly, perhaps the most difficult question that must be answered in general coastal design is: What are the forces acting on the structure? The following subjects will be discussed: - General Concepts - Case Histories - Nested Units In conclusion, I believe that with good coastal engineering, economical rubble mound structures can be designed, built, and maintained in exposed coastal locations. However, each site must be considered individually, and additionally, research must be undertaken to fully quantify loadings, stresses and design of concrete armor units to provide stable designs with appropriate safety factors.","rubble mound; structures; hydraulic; design; construction; breakwaters; ICCE 1992","en","report","ICCE 1992 local organising committee","","","","","","","","","","","","ICCE 1992",""
