  1. 1. Collisional transport in edge transport barriers and stellarators

    Author : Stefan Buller; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma physics; pedestal; collisional transport; fusion; stellarator; tokamak; transport; impurity transport;

    Abstract : 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. READ MORE

  2. 2. Turbulent and neoclassical transport in tokamak plasmas

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Istvan Pusztai; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Abstract : 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. READ MORE

  3. 3. Welfare Effects of Transport Policies an analysis of congestion pricing and infrastructure investments

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Jonas Westin; Lars-Göran Mattsson; Lars Hultkrantz; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion charge; cost-benefit analysis; tax distortions; transport investment; transport policies; welfare effects; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; SRA - Transport; SRA - Transport;

    Abstract : 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. READ MORE

  4. 4. Modelling and Appraisal in Congested Transport Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

    Abstract : 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. 5. Charge transport in polymer-based insulating materials for high voltage applications: effect of single- and multi-layered structures

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Tuan Anh Hoang; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; charge trapping and de-trapping; polyethylene; surface potential decay; enamel insulation; charge transport; charging current; charge injection; charge mobility; DC conductivity; nanocomposite;

    Abstract : 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. READ MORE
