    Författare :Anna Broms; Anna-Karin Tornberg; Mattias Sandberg; Eric Keaveny; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stokes flow; rigid particles; accuracy; fundamental solutions; method of images; multiblob; contact avoiding; complementarity problem; barrier method; elliptic PDE; grid optimisation; pair-correction; boundary integral equations; Stokesflöde; noggrannhet; stela partiklar; fundamentallösningar; randintegralekvation; reflektionspunkter; multiblob; kontaktundvikande algoritmer; komplementaritetsproblem; barriärmetod; elliptisk PDE; gridoptimering; parkorrektion; Numerical Analysis; Numerisk analys;

    Sammanfattning : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. LÄS MER

  3. 2. Empirical studies on sources of inequality

    Författare :Anna Sandberg; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This Ph.D. thesis in Economics consists of four self-contained chapters that empirically explore sources of economic inequality, using data from experiments, sports competitions, and Swedish registers. LÄS MER

  4. 3. Physical activity and exercise in patients with intermittent claudication

    Författare :Anna Sandberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accelerometry; Nordic walking; Peripheral artery disease; Quality of life; Reproducibility of result; Walk test;

    Sammanfattning : Introduction. Supervised exercise is a guideline recommendation in patients with intermittent claudication (IC). As the availability of supervised exercise varies, interest has turned to the more accessible home-based exercise programmes. LÄS MER

  5. 4. The value of simplicity : image browsing techniques and tests

    Författare :Anna Hedman; Karl W. Sandberg; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : Image browsing is involved in many different types of tasks, such as interacting with a desktop and file system, viewing digital photo albums, etc. Different techniques are available for different types of tasks, but results from image browsing tests have been varied. LÄS MER

  7. 5. Capturing Swedish Industry Transition towards Carbon Neutrality in a National Energy System Model

    Författare :Erik Sandberg; Andrea Toffolo; Anna Krook-Riekkola; Åsa Lindman; Isabela Butnar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Industry is responsible for approximately 30 % of the total emissions of greenhouse gases, both globally and in Sweden. Given the climate targets set out in the Paris agreement, the industry is facing a challenging future, requiring effective policies to aid the transition. LÄS MER
