2. Mechanical track deterioration due to lateral geometry irregularities
Abstract : This thesis deals with how a degraded track geometry influences further degradation of the geometry and the formation of rolling contact fatigue (RCF) and wear of rails. The overall objective is optimisation of railway maintenance. For this, further understanding and quantification of the deterioration of track components are needed. READ MORE

3. Influence of rail, wheel and track geometries on wheel and rail degradation
Abstract : For more efficient railway maintenance there is a need to increase the understanding of the influence of operational conditions on wheel and rail degradation. To this end, the chosen primary investigation strategy is to employ dynamic multibody simulations, where operational conditions are altered, to estimate the influence on material deterioration.

4. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels
Abstract : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. READ MORE

5. O⁺ heating in the high altitude cusp and mantle due to wave-particle interaction
Abstract : This thesis is composed of three articles, which have the common denominator that they are studies of heating of oxygen ions in the high altitude cusp and mantle in the terrestrial magnetosphere. All data analysis are based on observational data from the Cluster satellites. READ MORE
