van Winden, Joris (author)In this thesis we consider orbital stability of certain patterns in stochastic partial differential equations. We study two examples: a rotating wave in a twodimensional reactiondiffusion equation and a soliton in a parametrically forced nonlinear Schrödinger equation. In both cases, we show that, for small noise, solutions to the stochastic...master thesis 2022

Roodenburg, Floris (author)In this thesis we consider the incompressible and stationary Stokes problem with Navierslip boundary conditions on an infinite twodimensional wedge with opening angle θ. As is common for differential equations on domains with corners, the problem is decomposed into a singular expansion near the corner (polynomial problem) and a regular...master thesis 2022

Wisse, Anouk (author)This thesis treats the thinfilm equation which models the film height $h$ for a viscous film in the complete wetting regime. We show existence and uniqueness to the thinfilm equation with mobility m(h) = h<sup>n</sup> and mobility exponent n∈ (1,3/2)∪ (3/2,3). The thinfilm equation is rewritten as an abstract Cauchy problem and usage of semi...master thesis 2022

van Ooijen, Cas (author)This thesis is about the wave equation. The wave equation describes waves that propagate through a certain medium. The solution of the wave equation is a mathematical description of what that wave looks like. There are many fields of study where the wave equation is used to model processes that behave like travelling waves. For instance, a...bachelor thesis 2022

Wiarda, Sjoerd (author)In this thesis, we analyse the spectrum of the generator of the onedimensional ZigZag process defined on the torus $\mathbb{T}$. This is a piecewise deterministic Markov process (PDMP) used in Monte Carlo Markov chain methods (MCMC) for sampling from a probability distribution and calculating integrals \cite{Rejectionfree}, \cite{ZigZag}, ...master thesis 2021

Willems, Joshua (author)In various scientific disciplines, measurement data is collected across space and over time with the aim of inferring information regarding an underlying stochastic spatiotemporal phenomenon. The high computational costs of current methods render this task intractable for the large datasets typically encountered in spatiotemporal statistics. <br...master thesis 2021

Jonker, Stan (author)This thesis covers the power load flow problem and three numerical methods which can be used as a solution. We firstly discuss the concepts from electrical engineering required to discribe the problem. This includes alternating current and voltage and admittances of various electrical elements. We then use these concepts to derive a set of...bachelor thesis 2020

Wisse, A.C. (author)This thesis considers the thinfilm equation in partial wetting. The mobility in this equation is given by h<sup>3</sup>+λ<sup>3n</sup>h<sup>n</sup>, where h is the film height, λ is the slip length and n is the mobility exponent. The partial wetting regime implies the boundary condition dh/dz>0 at the triple junction....bachelor thesis 2020

Bonnema, D.M. (author)In this thesis we study the boundedness of a generalization of the HardyLittlewood maximal operator, involving rearrangement invariant Banach function space and indices of the spaces.<br/> We first consider a classical proof of boundedness of the HardyLittlewood maximal operator on rearrangement invariant Banach function spaces. After...bachelor thesis 2020

van den Bosch, Pascal (author)In this master thesis the proof of Lotz that Weak Lp spaces have the Grothendieck property is studied. The proof is slightly modified to be more explicit and easier to comprehend by introducing lemma’s to better separate different parts of the proof that more clearly reveal its structure. Furthermore, the more general Marcinkiewicz spaces are...master thesis 2019
