Van Dijk, T. (author), Schouten, H.F. (author), Visser, T.D. (author)We analyze the coherence singularities that occur in the far field that is generated by a broad class of partially coherent sources. It is shown that for rotationally symmetric planar quasihomogeneous sources the coherence singularities form a two-dimensional surface in a reduced three-dimensional space. We illustrate our results by studying the...journal article 2009

Smeets, P.W.M.H. (author), Medema, G.J. (author), Van Dijk, J.C. (author)The Netherlands is one of the few countries where chlorine is not used at all, neither for primary disinfection nor to maintain a residual disinfectant in the distribution network. The Dutch approach that allows production and distribution of drinking water without the use of chlorine while not compromising microbial safety at the tap, can be...journal article 2009

Van Dijk, L.A. (author)At universities there is a need to measure the quality of academic achievements in order to distribute available funds in a fair and objective manner. This happens based on the scientific journals in which the several departments publish. These, at their turn, are being judged on the number of citations an average article receives. However,...bachelor thesis 2009

Van Halem, D. (author), Bakker, S.A. (author), Amy, G.L. (author), Van Dijk, J.C. (author)For more than a decade it has been known that shallow tube wells in Bangladesh are frequently contaminated with arsenic concentrations at a level that is harmful to human health. By now it is clear that a disaster of an unheard magnitude is going on: the World Health Organization has estimated that long-term exposure to arsenic in groundwater,...journal article 2009

(author)The demand for high quality care is in contrast to reduced training time for residents to develop arthroscopic skills. Thereto, simulators are introduced to train skills away from the operating room. In our clinic, a physical simulation environment to Practice Arthroscopic Surgical Skills for Perfect Operative Real-life Treatment (PASSPORT) is...journal article 2009

Li, S. (author), Heijman, S.G.J. (author), Verberk, J.Q.J.C. (author), Van Dijk, J.C. (author)A new treatment concept for drinking water production from surface water has been investigated on a pilot scale. The treatment concept consists of fluidized ion exchange (FIEX), ultrafiltration (UF), nanofiltration (NF), and granular activated carbon filtration (GAC). The FIEX process removed calcium and other divalent cations; the UF membrane...journal article 2009

De Vet, W.W.J.M. (author), Van Genuchten, C.C.A. (author), Van Loosdrecht, M.C.M. (author), Van Dijk, J.C. (author)In drinking water production, river bank filtration has the advantages of dampening peak concentrations of many dissolved components, substantially removing many micropollutants and removing, virtually completely, the pathogens and suspended solids. The production aquifer is not only fed by the river bank infiltrate but also by water percolating...journal article 2009

Schot, M. (author), Desmet, P.M.A. (author), Van Dijk, M.B. (author), Schoone-Harmsen, M. (author)In this paper a design approach is introduced for designing products to increase happiness. Happiness reflects the degree to which people’s concerns are fulfilled. Based on this fact, a framework of all human concerns was created. After that, the framework was applied to a telehomecare case. Telehomecare products release the pressure on...conference paper 2009

(author)An “all pipes” hydraulic model of a DMA-sized drinking water distribution system was onstructed with two types of demand allocations. One is constructed with the conventional op-down approach, i.e. a demand multiplier pattern from the booster station is llocated to all demand nodes with a correction factor to account for the average water emand...journal article 2010

Van Dijk, J. (author), Stinissen, R. (author)Contemporary city-regions are facing major challenges concerning the relation between mobility and urbanity. A concrete example of this is the phenomenon of urban sprawl, which evolved in the US and also in Western Europe. The car is a very popular mode of transportation. However, the automobile has some serious spatial consequences. It had a...master thesis 2010
