Hoogendorp, G. (author), Popov, M. (author), Van der Sluis, L. (author)This letter deals with the hybrid modeling of transformers and the determination of interturn voltage distribution in transformers with layer-type windings. The hybrid model uses a combination of a multiconductor transmission-line model and a single transmission-line model. The good agreement between computed and measured voltage waveforms shows...journal article 2009

Van der Vegte, W.F. (author), Horváth, I. (author), Rusák, Z. (author)We introduce a methodology for modelling and simulating fully virtual human-artefact systems, aiming to resolve two issues in virtual prototyping: (i) integration of distinct modelling and simulation approaches, and (ii) extending the deployability of simulations towards conceptual design. We are going to offer designers a new way of...conference paper 2009

Kai, C. (author)Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...report 2009

Gerritsen, W. (author)Graduation project Hybrid buildings. The design is located on the Zeeburgerpad in Amsterdam. The program is a living room for the neighbourhood. The building shows the diversity of people using the building through vides, glass facades. The floor fields are stacked, the functions which need privacy are surrounded by a wooden volume. The building...master thesis 2009

Overeijnder, M.L. (author), Hagen, W.R. (author), Hagedoorn, P.L. (author)Pyrococcus furiosus hybrid cluster protein (HCP) was expressed in Escherichia coli, purified, and characterized. This is the first archaeal and thermostable HCP to be isolated. Compared with the protein sequences of previously characterized HCPs from mesophiles, the protein sequence of P. furiosus HCP exhibits a deletion of approximately 13 kDa...journal article 2009

Hoogendorp, G. (author)The aim of this thesis is to calculate the primary inter-turn voltage distributions when the medium voltage single phase power transformer is subjected to a step voltage. This culculation is performed by considering the turns of the primary winding as transmission lines. In this thesis, the hybrid model, a combination of single transmission line...master thesis 2009

Sewagudde, S. (author)The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...report 2008

Van der Vegte, W.F. (author), Horváth, I. (author)The approach described in this paper aims to offer designers a new way to investigate use processes of products by integrating scenarios of expected user behaviour with simulations of physical artefact behaviour. Use is considered a key process in the life cycle of a product, being the phase in which an instance of a product is put into service...conference paper 2007

Helmerhorst, G.J. (author)In de huidige praktijk van gebiedsontwikkelingsprojecten vindt het besluitvormingsproces plaats in pluricentrische besluitvormingsarenas, waarin sprake is van interorganisatorische planning. Door de wederzijdse afhankelijkheid tussen de partijen in deze arenas, de daaraan verbonden steeds wisselende partnerschappen en het onbekende eindresultaat...master thesis 2007

de Bruijn, F.T. (author)The combination of conventional unit operations with pervaporation or vapour permeation membrane separation processes offers opportunities for process intensification in terms of augmenting capacity and decreasing energy consumption of conventional unit operations. The MTBE production process is an often studied example of a so-called hybrid...doctoral thesis 2006

Necoara, I. (author)This Ph.D. thesis considers the development of new analysis and control techniques for special classes of hybrid systems and discrete event systems. Two particular classes of hybrid systems (piecewise affine systems and max-min-plus-scaling systems), and two particular classes of discrete event systems (max-plus-linear systems and switching max...doctoral thesis 2006

Jing, H. (author), Li, C. (author), Zhou, B. (author)In this paper, some five-point finite difference schemes for steady convection-diffusion problems are presented. To begin with, we use the finite volume method (FVM) to discretize the convection-diffusion equation. After that, we present two five-point difference schemes for the approximation of the first order derivatives on faces, one of which...conference paper 2006

Peng, S.H. (author)A detached eddy simulation modelling approach is presented for turbulent flow computations, which is based on the transport equation for turbulent kinetic energy, k (and thus termed k-DES model). The model coefficients in the RANS form are calibrated in wall-attached flow computations, and the LES mode is calibrated in the simulation for...conference paper 2006

Sasaki, D. (author), Dhanesekaran, C. (author), Dawes, B. (author), Shahpar, S. (author)Automatic robust unstructured hybrid meshing is indispensable for the success in design optimisation. In addition, it is important to maintain the mesh quality for deformation of geometry throughout the optimisation process for the reliability of optimal design. Mesh adaptation is useful to capture the flow feature which can highly affect flow...conference paper 2006

Selmin, V. (author), Pelizzari, E. (author), Ghidoni, A. (author)This paper describes a fully automatic 3D anisotropic mesh generation method for domains of arbitrary shape. The spacing of the boundary mesh is computed by the analysis of the principal curvatures and directions of the boundary surfaces. The spacing in the domain is obtained by interpolation of the spacing at the boundaries on a suitably...conference paper 2006
