1. Welfare Effects of Transport Policies : an analysis of congestion pricing and infrastructure investments
Sammanfattning : Interactions between the transport market and other distorted markets, such as the labor market, can have a large impact on the overall welfare effect of a road pricing policy or a congestion charge. Many road pricing studies therefore try to incorporate effects from other distorted markets in the analysis. LÄS MER
2. Collisional transport in edge transport barriers and stellarators
Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER
3. Turbulent and neoclassical transport in tokamak plasmas
Sammanfattning : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. LÄS MER
4. Modelling and Appraisal in Congested Transport Networks
Sammanfattning : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

5. Charge transport in polymer-based insulating materials for high voltage applications: effect of single- and multi-layered structures
Sammanfattning : Polymer composites have been widely employed as electrical insulating materials for high voltage components and devices such as power cables, gas-insulated systems, rotating machines, line and post insulators, etc. Such materials are usually made by introducing inorganic oxides (SiO2, TiO2, Al2O3, MgO) into polymeric matrices e.g. LÄS MER
