1. Itô Diffusions on Level Sets
University essay from Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data scienceAbstract : Itô diffusions that move on level sets of functions in Rn, which we have called level processes, are an overlooked variant of the classical Itô processes. These processes find themselves nestled between the study of regular Itô diffusions in Rn and diffusions which are bound to smooth manifolds. READ MORE

2. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems
University essay from Uppsala universitet/Tillämpad beräkningsvetenskapAbstract : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. READ MORE

3. Optimal Multitaper Spectrograms
University essay from Lunds universitet/Matematisk statistikAbstract : Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. READ MORE

5. Gradients of the Poisson Equation using a Stochastic Method
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this report, a recently discovered numerical method has been tested and shown to be viable. The method aims to calculate the gradient of the solution of a bounded Poisson equation, specifically: 1/2 ∇² φ + f |G = 0, φ(x) |∂G = 0, (0.1) where G is some open domain. READ MORE
