Buwalda, Floris (author)In the past 15 years the field of general purpose computing on graphics processing units, or GPUs, has become well developed and the practice is becoming more mainstream. Computational demands of simulation software are continuously increasing. As such for many applications traditionally computed on the central processing unit the question...master thesis 2020

Atsma, Michael (author)In this thesis, we look at the traditional way of calculating a ship’s PowerSpeed function using the Iterative Method, and then compare this to the renewed method created by Michaël Mersie, called the Direct Method. We find that, only under very specific circumstances, the Iterative Method can be slightly better at estimating the function of...bachelor thesis 2019

Vis, Simone (author)During oil drilling, the position of wells is indirectly determined by measurements near the drilling bit. However, the measurements are disturbed by noise causing errors in the measurements. It is important for large oil companies like Shell to determine the position of wells with a certain degree of uncertainty. Therefore, the main objective...bachelor thesis 2019

Vree, Pim (author)Report about how Matrix Product States can be used to analyze a sub set of problems in quantum mechanics. A exact derivation is given of the Ising Model in a Transverse field and with these solutions the TEBD algorithm using Matrix Product states is validated.bachelor thesis 2019

Verbist, Victor (author)A model is developed to simulate NaCl concentrations across a cation exchange membrane in the transient regime. The convectionless NersntPlanck equation is combined with the continuity equation to obtain a partial dierential equation in time and space. The boundary conditions at the edges of the cell for this equationare a constant bulk...bachelor thesis 2019

Knipping, Jorien (author)Wavelets have been very popular in the field of image compression and noise reduction. Another interesting application is adaptive mesh refinement. There are many wavelets with various properties, which will have different effects on different applications. There is no consensus on which wavelet is the best option for adaptive mesh refinement....master thesis 2018

Teitsma, Jacco (author)In this thesis, the methods of Matrix Product States are examined. We give background in the origin of the methods and explain in detail how the method can be applied to a series of Josephson junctions. Numerical results are given for the ground state energy analysis of these series.bachelor thesis 2018

Van, Huy (author)In wellbore engineering, oilwell boreholes are made using specialized drilling rigs. The position of the drill bit needs to be indirectly determined through accelero and magnetometer measurements. To this end, the measurement data is first converted into a survey of direction vectors by applying a series of coordinate transformations. Then, a...bachelor thesis 2018

Peeters, Lotte (author)In this thesis, a coupled hydrodynamic, morphodynamic and plant growth model is reviewed. The goal of this model is to simulate plant colonization and channel formation on an initially flat or ascending substrate in a tidal landscape. To be able to simulate these biophysical processes on a small enough scale (while still using the same spatial...master thesis 2018

Maring, Sandra (author)Gasunie Transport Services (GTS) is the operator of the natural gas transmission network in the Netherlands. This network is an entryexit system where entry and exit capacities can be booked by parties called shippers. Variations in usage lead to an enormous number of possible entryexit combinations. GTS must be able to accommodate all...master thesis 2018

de Rooij, Tim (author)Timefrequency analysis and digital signal processing are important tools in the field of coastal engineering. Both can be done using techniques like Fourier or wavelet analysis, however, analysts from this field experience a threshold to use wavelet analysis instead of their current methods, often Fourierbased. This is due to the lack of...master thesis 2017

Boitcov, Dmitrii (author)Existing multiscale solvers use a sequence of aggressive restriction, coarsegrid correction and prolongation operators to handle lowfrequency modes on the coarse grid. Highfrequency errors are resolved by employing a smoother on the fine grid. Deflation preconditioning improves matrix properties, i.e., damps slowly varying errors,...master thesis 2017
 document

Mersie, Michaël (author)The aim of this research is to evaluate two different current correction methods: the "Iterative" Method, that has (partly) replaced the traditional "Mean of means"Method and is currently in use, and the "Direct"Method, amore fundamental and mathematical approach to the problem. These methods were both developed to determine the speed of a ship...bachelor thesis 2017

Rozendaal, Marco (author)In this thesis, it is investigated how the blood flow changes in different physiological situations, using a onedimensional model, that describes the blood flow in compliant vessels. The onedimensional model, that describes the blood flow, is derived based on the physical laws of conservation of momentum and conservation of mass. A high...bachelor thesis 2017

Jonoski, Ilin (author)In proton therapy the development of dose calculation methods is of great importance<br/>to optimize the dose. In this work a method is presented to solve the FokkerPlanck<br/>transport equation using raytracing techniques and nite element methods.<br/>The idea of the method is dividing the FokkerPlanck equation in two seperate equa<br/...bachelor thesis 2017

Meijers, Onno (author)To get a clear picture of the earth crust the Helmholtz equation needs to be<br/>solved and a high wave number is needed in order to provide fine grain details.<br/>The Stabilised BiConjugate Gradient method needs to be implemented to solve<br/>the Helmholtz equation. This is done on a Maxeler data flow machine to improve<br/>calculation times....master thesis 2017

Dolas, Sagar (author)"What Mathematics is to Physics, Data traversal is to Highperformance computing." The world of Computational science has witnessed an exponential expansion of sophisticated numerical algorithms in the last few decades mainly to understand minute details and solve complex physical problems. It has established itself as the third pillar of...master thesis 2017

Diepeveen, Willem (author)We have explored the concept of mobile computational fluid dynamics (CFD) solving. Using the computational<br/>power of a smartphone we tried to generate real time simulations of relatively simple transient natural<br/>convection problems in the laminar regime. The focus lies on finding a compromise between accuracy, speed<br/>and stability: we...bachelor thesis 2017

Gorter, Wilbert (author)Allerlei diffusieverschijnselen in de natuurkunde kunnen omschreven worden<br/>met de Poissonvergelijking op een gebied met te kiezen randvoorwaarden. Er zijn echter ook verschijnselen waarin er een gelaagdheid optreedt zodat er in verticale<br/>richting minder makkelijk diffusie kan plaatsvinden. Dit leidt tot een vergelijking<br/>met...bachelor thesis 2017
