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

    Författare :Stefan Buller; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma physics; pedestal; collisional transport; fusion; stellarator; tokamak; transport; impurity transport;

    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

  2. 2. Radially global neoclassical transport in tokamak pedestals

    Författare :Stefan Buller; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamak; transport; global effects; collisional transport; fusion; drift-kinetics; plasma physics;

    Sammanfattning : Nuclear fusion has the potential to become a sustainable energy sourcein the foreseeable future. The most developed system for fusion powerproduction is the tokamak, which magnetically confines a plasma at highenough temperature for fusion reactions to take place. LÄS MER

  4. 4. Tyre-road Interaction: a holistic approach to noise and rolling resistance

    Författare :Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Anders Genell; Hans Jonasson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; pavement; surface; texture; noise; rolling resistance; tyre; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Energy dissipation, fuel consumption, real-estate property prices and health issues are some of the aspects related to the tyre/pavement interaction and its functional properties of rolling resistance and noise. The first two aspects are affected by the tyre/road interaction as energy is dissipated mostly by hysteretic losses as the tyre is subjected to dynamic deformations when contacting the pavement surface.

  5. 5. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance

    Författare :Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Tony Parry; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; surface; noise; rolling resistance; tyre; mitigation; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Building Materials; Byggnadsmaterial;

    Sammanfattning : Increased fuel consumption, increased greenhouse gas emission, diminishing real-estate prices and increased health issues are some of  the negative effects on the climate, on the environment and on the society from tyre/road rolling resistance and noise. The first two aspects are affected by energy dissipation in the tyre/pavement contact and are related to rolling resistance. LÄS MER
