Chen, Y. (author), Veer, F.A. (author), Copuroglu, Oguzhan (author)Concrete is by volume the most widely used building material all over the world. The concrete industry emits large quantities of greenhouse gases. Therefore, developing low CO2 concrete becomes an urgent issue for those countries with significant concrete production and consumption. In recent years, 3D concrete printing (3DCP) which is a new...review 2017

Veer, F.A. (author), Bristogianni, T. (author), Baardolf, G. (author)Spontaneous failures in thermally toughened glass are frequently reported, although the actual percentage is quite small, suppliers in the Netherlands reporting one or two cases a year while thousands of tempered panels are supplied. These cases are rarely investigated in the Netherlands because the broken thermally toughened glass is usually...journal article 2017

Bluyssen, P.M. (author)From previous and recent studies is clear that an indoor environment of a school, may affect the health, comfort and performance of schoolchildren. Besides the occupants and their activities, the windows and the outdoor environment and the type of ventilation system, the interior (furnishing incl. flooring materials) is an important contributor...journal article 2016

Krishna, Hedi (author), van Adrichem, N.L.M. (author), Kuipers, F.A. (author)Quality of Service (QoS) control is an important concept in computer networking, as it is related to end-user experience. While providing QoS guarantees over the Internet has long been deemed too complicated, the emergence of Software- Defined Networking (SDN), and OpenFlow as its most popular standard, may facilitate QoS control.<br/>In this...conference paper 2016

Arfan (author)Background and Purpose - The presence of subclinical vascular brain disease, including white matter lesions and lacunar infarcts, substantially increases the risk of clinical stroke. White matter microstructural integrity is considered an earlier, potentially better, marker of the total burden of vascular brain disease. Its association with...journal article 2016

Prest, E.I.E.D. (author), Weissbrodt, D.G. (author), Hammes, F (author), van Loosdrecht, Mark C.M. (author), Vrouwenvelder, J.S. (author)Large seasonal variations in microbial drinking water quality can occur in distribution networks, but are often not taken into account when evaluating results from short-term water sampling campaigns. Temporal dynamics in bacterial community characteristics were investigated during a two-year drinking water monitoring campaign in a full-scale...journal article 2016

Biljecki, F. (author), Ledoux, H. (author), Du, X. (author), Stoter, J.E. (author), Soon, Kean Huat (author), Khoo, Victor (author)To be used as input in most simulation and modelling software, 3D city models should be geometrically and topologically valid, and semantically rich. We investigate in this paper what is the quality of currently available CityGML datasets, i.e. we validate the geometry/topology of the 3D primitives (Solid and MultiSurface), and we validate...conference paper 2016

Taucer-Kapteijn, M. (author), Hoogenboezem, Wim (author), Medema, G.J. (author)Soil passage through sand dunes has previously been shown to remove enteric micro-organisms very effectively, and hence is used for the production of drinking water. However, enterococci have occasionally been isolated from abstracted water (after dune passage) in one of the dune infiltration areas in the Netherlands. Enterococcus moraviensis...journal article 2016

Palomba, F. (author), Panichella, A. (author), Zaidman, A.E. (author), Oliveto, Rocco (author)Test case generation tools that optimize code coverage have been extensively investigated. Recently, researchers have suggested to add other non-coverage criteria, such as mem- ory consumption or readability, to increase the practical use- fulness of generated tests. In this paper, we observe that test code quality metrics, and test cohesion and...conference paper 2016

Heck, P.M. (author)The goal of this thesis was to obtain a deeper understanding of the notion of quality for Just-in-Time (JIT) Requirements. JIT requirements are the opposite of up-front requirements. JIT requirements are not analyzed or defined until they are needed meaning that development is allowed to begin with incomplete requirements. We started our...doctoral thesis 2016

Grünewald, S. (author), Schipper, H.R. (author), Hordijk, D.A. (author)The number of applications with thin flat, curved or double-curved elements often produced as architectural elements for façades is rising fast. If the repetition factor of the elements is limited, which is often the case in free-form architecture, the high number of unique moulds makes this type of architecture economically less viable....conference paper 2016

Knowledge of the precise position of each radar scatterer is essential to identify the corresponding object and interpret the estimated deformation. The absolute position accuracy of synthetic aperture radar (SAR) scatterers in...journal article 2016

Stanic, N. (author)Asset management is a tool for maintaining the required level of serviceability of urban drainage systems, which are costly to construct and in some cases even more costly to replace. The required asset management effort to achieve a certain level of service is unclear due to a limited knowledge on sewer failure mechanisms and due to scarcity of...doctoral thesis 2016

Ramos, C.A. (author)The context for this thesis is the concern that people who practice physical activity are more susceptible to air pollution. For the studies presented here, three perspectives of physical activity were considered: in indoor, i) physical activity in fitness centers; in outdoor ii) the use of bicycle in cycle paths; and iii) active transportation....doctoral thesis 2016
