1. Finite Difference Methods for Time-Dependent Wave Propagation Problems
Abstract : Wave propagation models are essential in many fields of physics, such as acoustics, electromagnetics, and quantum mechanics. Mathematically, waves can be described by partial differential equations (PDEs). In most cases, exact solutions to wave-dominated PDEs are nearly impossible to derive. READ MORE

2. Computational Solid Wave Propagation Numerical Techniques and Industrial Applications
Abstract : For wave propagation and many other physical phenomena, the dynamic effects are vital. In industrial applications, such problems are very complex and generally have to be treated by means of numerical methods. READ MORE

3. Multiscale Methods for Wave Propagation Problems
Abstract : Simulations of wave propagation in heterogeneous media and at high frequencies are important in many applications such as seismic-, {electro-magnetic-,} acoustic-, fluid flow problems and others. These are classical multiscale problems and often too computationally expensive for direct numerical simulation. READ MORE

4. On the Modelling of Train Induced Ground Vibrations with Analytical Methods
Abstract : A novel analytical approach to model train induced ground vibrations is proposed. Integral transform solutions are combined with series solutions to obtain fast numericalalgorithms, where a particular designed boundary condition for finite regions is seen to enable the solution procedure.

5. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography
Abstract : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. READ MORE
