16. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques
University essay from KTH/Teknisk akustikAbstract : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. READ MORE

17. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren
University essay from KTH/Jord- och bergmekanikAbstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE

18. Computation of Acoustic Wave Propagation Under Water
University essay from KTH/Matematik (Avd.)Abstract : In this thesis we look at acoustic wave propagation under water. We look in particular at waves generated by a point source and what happens with the propagation when we model the bottom as flat or as curvilinear. We assume the source to be working at a certain frequency and therefore we model this problem by solving the Helmholtz equation. READ MORE

19. Computation of Effective Local Diffusion Tensor
University essay from KTH/FysikAbstract : Numerical simulations of large complex systems such as biomolecules often suffer from the full description of the system having too many dimensions for direct numerical calculations and Monte Carlo methods having trouble overcoming energy barriers. It is therefore desirable to formulate a description in lower dimension which captures the system’s macroscopic behaviour. READ MORE

20. Approximating Quasistationary Distributions Using Deep Learning
University essay from KTH/Matematisk statistikAbstract : We study a class of It\={o} diffusion processes on domains with smooth boundary, at which the process is killed. Such a process, when conditioned on non-extinction, gives rise to a stationary state known as a \emph{quasistationary distribution} (QSD). READ MORE
