1. Simulations of a self-stabilizing fully submerged hydrofoil
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. LÄS MER
2. Gap Probabilities in Random Matrix Ensembles
Kandidat-uppsats, Uppsala universitet/Analys och partiella differentialekvationerSammanfattning : In this degree project we look at eigenvalue statistics of two randommatrix ensembles, the Gaussian and the circular ensembles. We beginwith their definition and discuss the joint probability distribution of theirentries and eigenvalues. LÄS MER
3. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER
4. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions
Kandidat-uppsats,Sammanfattning : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. LÄS MER
5. Cospectral graphs : What properties are determined by the spectrum of a graph?
Kandidat-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorikSammanfattning : This paper was written as a bachelor thesis in mathematics. We study adjacency matrices and their eigenvalues to investigate what properties of the corresponding graphs can be determined by those eigenvalues, the spectrum of the graph. The question of which graphs are uniquely determined by their spectra is also covered. LÄS MER
