Goudswaard, Reef (author)This bachelor's thesis explores the realm of map projections, aiming to establish a systematic approach for evaluating and ranking them based on angular and area distortions. Beginning with a definition of map projections, the study progresses to quantify the distortions that occur when projecting a spherical surface onto a flat one. Using these...bachelor thesis 2024

Ledoux, Rik (author)In this thesis, we derive a multivariate analogue of Ruijsenaars’s 2F1generalisation R. We use Hopf algebra representation theory of the modular double of sl.2/, a Hopf algebra structure strongly related to quantum groups, to relate the function R to overlap coefficients of eigenfunctions. Using properties of the algebra and the representation,...master thesis 2023

Verton, Max (author)We analyze the spatially discretized version of the AllenCahn partial differential equation. The second order derivative is numerically approximated by a weighted infinite sum. The coefficients of this sum as well as the function f in the differential equation have got freedom inside determined restrictions. For this spatially discretized...bachelor thesis 2023

Pantova, Dona (author)Due to their ecological significance and their role in providing grounds for a variety of human activities, understanding how tidal inlet systems evolve is of interest to scientists, engineers, and managers. The seabed profile in such systems evolves due to the erosion and deposition of sediment particles from and onto the seabed. Equivalently,...master thesis 2021

Babu Gheethaa, Mukkund (author)A highresolution hydrological solver that solves on timeadaptive grids is created. The solver uses hrefinement strategies which adapts the resolution of the grid using a posteriori measure. It is based on an opensource scientific computing library named PETSc. With the use of highly scalable timestepping solvers provided by PETSc, an...master thesis 2020

de Koning, Bart (author)In this thesis we examine various aspects of the output signal produced by the electrical pickup of an electric guitar. We do this by formulating a model of this output signal based on the one dimensional damped wave equation for the motion of one guitar string and (initially) a simple linear model for the output signal based on this motion....bachelor thesis 2019

den Hertog, Wilbert (author)The numerical errors involving the application of the levelset method to a problem can be minimized by fitting a mesh (usually a triangular mesh in two dimensions) to the zero levelset curve defined by the levelset function. These numerical errors depend on two things: the size and skewness of the triangles in the mesh. To fit the mesh, Timo...bachelor thesis 2019

Kenjeres, S. (author), Hanjalic, K. (author)We report on hybrid numerical simulations of a turbulent magnetic dynamo. The simulated setup mimics the Riga dynamo experiment characterized by Re ? 3.5 × 106 and (Gailitis et al 2000 Phys. Rev. Lett. 84 4365–8). The simulations were performed by a simultaneous fully coupled solution of the transient Reynoldsaveraged Navier–Stokes (TRANS)...journal article 2007
