1. Rough Scatterers in Acoustics and Elastodynamics
Sammanfattning : The purpose of this thesis is to investigate the influence of roughness on wave scattering from finite-sized surfaces, in particular elastic wave scattering from cracks. Acoustic scattering from a sphere is considered using the null field approach. LÄS MER
2. Analytical methods of solution to eddy current interaction problems
Sammanfattning : The eddy current method is used for nondestructive evaluation of conducting materials. To achieve a greater knowledge and insure safe and reliable evaluation methods, the use of mathematical models is needed. LÄS MER

5. Light scattering and absorption in tissue - models and measurements
Sammanfattning : In this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases.
