Schipper, H.R. (author), Grünewald, S. (author), Eigenraam, P. (author), Raghunath, P. (author), Kok, M.A.D. (author)Free-form buildings tend to be expensive. By optimizing the production process, economical and well-performing precast concrete structures can be manufactured. In this paper, a method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single element. The...conference paper 2014

Klerk, W.J. (author), Kok, M. (author), de Bruijn, K.M. (author), Jonkman, S.N. (author), van Overloop, P.J. (author)In the Netherlands, flood risk analysis is usually carried out for a location, without considering potential flood defence failures in upstream areas. This may result in significant over- or underestimation of flood risks. The effect of upstream failures on failure probabilities and flood risks in other areas is called load interdependence of...conference paper 2014

Lendering, K.T. (author), Jonkman, S.N. (author), Kok, M. (author)During flood events emergency measures are used to prevent breaches in flood defences. However, there is still limited insight in their reliability and effectiveness. The objective of this paper is to develop a method to determine the reliability and effectiveness of emergency measures for flood defences. The investigation is focused on measures...conference paper 2014

Kok, J.C. (author), Van Muijden, J. (author), Burgers, S.S. (author), Dol, H. (author), Spekreijse, S.P. (author)Scientific enhancement of the analysis of thermal comfort aspects in aircraft cabins is the subject of the current investigation. For this purpose, three important processes are identified that play a significant role in thermal comfort, viz. the human response to its thermal environment which is also known as thermoregulation, the actual...conference paper 2006

(author)A systematic grid convergence study is conducted for the Detached-Eddy Simulation (DES) of the massively separated flow around a NACA0021 airfoil at high angle of attack. In order to study the convergence characteristics of DES/LES problems, velocity fields using a series of grids must be generated that demonstrate sufficient dynamic similarity...conference paper 2006

Kok, R. (author)This paper assesses the impacts of a CO2-differentiated tax policy designed to influence car purchasing trends towards lower CO2 emitting vehicles in the Netherlands. Since 2009, gasoline and diesel cars up to 110 and 95 gram CO2 per km are exempted from the vehicle registration tax (VRT). In addition, in 2010 a first step was implemented to...conference paper 2011

(author)This paper explores new methods to visualize and fuse multi-2D bioluminescence imaging (BLI) data with structural imaging modalities such as micro CT and MR. A geometric, back-projection-based 3D reconstruction for superficial lesions from multi-2D BLI data is presented, enabling a coarse estimate of the 3D source envelopes from the multi-2D BLI...conference paper 2007

A better understanding of relationships between rainfall characteristics and rainfall-related damage can help insurers and flood authorities to respond more adequately to rainfall extremes. This paper aims to study to what extent weather radars can be...conference paper 2013

Van der Krogt, M.G. (author), Van den Ham, G.A. (author), Kok, M. (author)Flow sliding of submerged slopes in front of dikes can affect the reliability of flood defences. The occurrence of flow sliding may result, sometimes with delay, in a failure mode and consequent flooding. The current safety assessment method for flow sliding does not consider the interaction between flow sliding and failure modes which can cause...conference paper 2015

Kok, J.C. (author)A new high-order, finite-volume scheme is presented that preserves the symmetry property and the dispersion relation of the convective operator. The scheme is applied to large-eddy simulation of compressible, turbulent flow and to the solution of the linearized Euler equations for aeroacoustic applications. For large-eddy simulation, the...conference paper 2006
