1. Atmosphere-ocean Interactions in Swell Dominated Wave Fields
Sammanfattning : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. LÄS MER
2. Surface Wave Testing of Pavements
Sammanfattning : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. LÄS MER
3. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography
Sammanfattning : 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. LÄS MER
4. Theoretical Investigation on Propagation and Coupling of Nonreciprocal Electromagnetic Surface Waves
Sammanfattning : This thesis aims at revealing the fundamental guiding and coupling properties of nonreciprocal electromagnetic surface waves on magneto-optical or gyromagnetic media and designing novel applications based on the properties.We introduce the background in the first chapter. LÄS MER
5. Summation-by-Parts Finite Difference Methods for Wave Propagation and Earthquake Modeling
Sammanfattning : Waves manifest in many areas of physics, ranging from large-scale seismic waves in geophysics down to particle descriptions in quantum physics. Wave propagation may often be described mathematically by partial differential equations (PDE). Unfortunately, analytical solutions to PDEs are in many cases notoriously difficult to obtain. LÄS MER
