Neijenhuis, R.W.A. (author)Ieder jaar zijn er veel evenementen waar duizenden of zelfs miljoenen mensen op afkomen. Denk bijvoorbeeld aan muziek-, cultuur- en sportevenementen. Daarnaast gebruiken miljoenen mensen dagelijks plekken als stations of winkelcentra. Bij al deze voorbeelden ontstaan gigantische mensenmassa's die gecontroleerd moeten worden zodat de...bachelor thesis 2015

Maring, S. (author)Online sociale netwerken zijn in deze tijd populair en de eigenaren van deze netwerken kunnen hierdoor met veel gebruikers goed geld verdienen. Voor hen en ook bijvoorbeeld mensen met aandelen in het sociale netwerk is het belangrijk om te weten hoe het gebruikersaantal in de tijd gaat verlopen. Met het epidemiologische SIR-model en vier...bachelor thesis 2015

Gravendeel, R.J. (author)Google PageRank is an algorithm incorporated by Google to rank websites, using the amount of links a website has as well as the importance of each link. This process can be calculated using the power method. As the amount of websites grows it is essential to speed up this process. Two extrapolation methods, Aitken Extrapolation and Quadratic...bachelor thesis 2015

Altmann, K. (author)In recent years, the use of differential equations in connection with algebraic constraints on the variables has become a widely accepted tool for modeling the dynamical behaviour of physical processes. Compared to ordinary differential equations (ODEs), it has been observed that a number of difficulties can arise when numerical methods are used...master thesis 2015

Mul, M.M. (author)A three-dimensional mixed-mode cellular automaton model [C. Bos, M. G. Mecozzi, and J. Sietsma. Computational Materials Science 48.3 (2010): 692-699] for the austenite to ferrite transformation in low-carbon steel has been analyzed and improved. A comparison between the new and conventional model has been made and the improvements found are...master thesis 2014

Loh, K.K.L. (author)This thesis is a study on the implementation of the Gaussian Markov Random Field (GMRF) for random sample generation and also the Multilevel Monte Carlo (MLMC) method to reduce the computational costs involved with doing uncertainty quantification studies. The GMRF method is implemented in different programming environments in order to evaluate...master thesis 2014

Wobbes, E.D. (author)Algebraic Multigrid (AMG) is an efficient multigrid method for solving large problems, using only the information provided by the underlying matrices. Unfortunately, on a parallel machine the performance of AMG can be negatively affected by dense communication patterns. The exchange of extensive data sets is generally caused by a high number of...master thesis 2014

Mittal, A. (author)The project focuses on developing a simulator in which ships and waves interact. The new wave model is the Variational Boussinesq model (VBM). However, this new realistic model brings much more computation effort with it. The VBM mainly requires an unsteady state solver, that solves a coupled system of equations at each frame (20 fps) . The...master thesis 2014

Óskarsdóttir, A. (author)Some cases of infant skull fracture fall under the category of forensic study where it is not obvious whether the head trauma happened due to an accident or abuse. To be able to determine the cause of the head trauma with sufficient accuracy, biomechanical analysis using finite element modeling of the infant cranium has been established. By...master thesis 2014

Wijchers, M.S. (author)In this thesis a special kind of differential equation will be analysed, namely the delay differential equation. For test equations the stability behaviour is analysed and there's checked whether there is a method to prove stability. Also, a full description is given, for the model submitted by INCAS3.bachelor thesis 2014

Vonk, S.M. (author)In dit verslag is er gekeken naar de legionellabacterie en de ontwikkeling hiervan in een warmwaterleiding. Alleerst is het model opgesteld voor de temperatuur van het water in de leiding. Vervolgens is de ontwikkeling van de legionellabacterie gemodelleerd, met twee verschillende modellen: het standaard model en het begrensde model. Het...bachelor thesis 2014

Van Heerden, E. (author)Quantification of non-viable cells in bright-field microscope images allows for an in vitro assessment of the viability of cultured cells. The identification and quantification of non-viable cells in a cell culture is conventionally achieved with viability stains. A disadvantage of viability stains is that they might be invasive and even toxic...master thesis 2014

Van der Linden, J.H. (author)Extreme and isolated eigenvalues are known to be harmful to the convergence of the iterative solver. These eigenvalues are produced by strong heterogeneity in the underlying physics. We can improve the quality of the spectrum by ‘deflating’ the harmful eigenvalues. In this thesis, deflation is applied to linear systems in reservoir simulation....master thesis 2013

Wagenaar, C. (author)Bij een CD wordt de informatie opgeslagen in een metaallaag. Bij het beschrijven van zo'n CD wordt het metaal door een laser verwarmd, zodat het metaal plaatselijk gaat smelten. Om de plaats van het smeltfront te bepalen kan gebruik worden gemaakt van de Moving Grid methode. Dit is een methode om bij numerieke tijdsintegratie het grid mee te...bachelor thesis 2013

Lindenberg, K. (author)In dit verslag wordt het stabiliteitsgedrag van een model, aangeleverd door INCAS3, onderzocht. In dit model wordt als tijdsintegratiemethode de methode Modied Sielecki gebruikt. Vervolgens wordt in dit model de vierde orde tijdsintegratiemethode Runge-Kutta (in plaats van de methode Modied Sielecki) geïmplementeerd. Voor beide methoden wordt...bachelor thesis 2013

Fan, B. (author)In this project we introduce the sintering process, which involves two basic phenomena, pore shrinkage and grain growth, occurring simultaneously. The objective of this project is to quantitatively describe the sintering process incorporating the kinetics of pore shrinkage and grain growth. First we build a model for pore shrinkage separately....master thesis 2013

Bookholt, F.D. (author)In this thesis, we learn the structure of a hybrid Bayesian network (mixed continuous and discrete) for a small data set and learn the parameters. We segment the learning process in distinct steps and evaluate the possible options for each step. After a short introduction into the theory of Bayesian networks, we cover the topics: data...bachelor thesis 2013
