  1. 1. Turbulent and neoclassical transport in tokamak plasmas

    Författare :Istvan Pusztai; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    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

  3. 2. The Public Transport Preferences of Elderly People; A study related to individual capacity and environmental stress in service route traffic and other systems

    Författare :Helena Svensson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walking distance; valuation; standard factors; conjoint analysis; stated preference method; trunk routes; special transport; service routes; restrictions; physical capacity; preferences; travellers; public transport; elderly people; traffic planning; Road transport technology; Vägtransportteknik;

    Sammanfattning : Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. LÄS MER

  4. 3. Models and algorithms for integrated special transport services

    Författare :Marcus Posada; Jan Lundgren; Carl-Henrik Häll; Peter Schütz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An essential challenge for all societies is to provide efficient and effective means of transporting people. Transport systems and transport infrastructure play an integral part in society both by providing a basis for social and economic development and as the physical structure which defines our environment.

  5. 4. Modelling and Simulating Demand-Responsive Transport

    Författare :Sergei Dytckov; Jan A. Persson; Paul Davidsson; Erik Jenelius; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Demand Mobility; Demand Responsive Transport; Modelling and Simulation; Sustainability;

    Sammanfattning : Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. LÄS MER

  7. 5. Energy system perspectives on transport biofuel policies – a modelling analysis

    Författare :Martin Börjesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cost-optimization; biofuels; linear programming; fuel tax; district heating; biomass gasification; model; transport; energy systems; MARKAL;

    Sammanfattning : Climate concerns and energy security issues have in recent years triggered the interest in biofuels for transport. This has resulted in governmental and intergovernmental targets that, if implemented, will lead to an unprecedented growth in biofuel production. LÄS MER
