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

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

    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

  4. 2. Radially global neoclassical transport in tokamak pedestals

    Author : Stefan Buller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamak; transport; global effects; collisional transport; fusion; drift-kinetics; plasma physics;

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  7. 5. Employees with Aided Hearing Impairment : An Interdisciplinary Perspective

    Author : Håkan Hua; Björn Lyxell; Claes Möller; Stephen Widén; Gunnel Backenroth; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing impairment; cognitive skills; noise; labor market; Hörselnedsättning; kognitiva förmågor; buller; arbetsmarknad;

    Abstract : In Sweden 13% of the general adult population (16-84 years), with or without hearing aids (HAs), report that they have difficulties following a conversation when more than two people are involved. This means that more than one million people in Sweden (9 500 000 inhabitants in total) report subjective hearing difficulties. READ MORE
