  1. 16. Numerical computations of wind turbine wakes and wake interaction : Optimization and control

    Författare :Karl Nilsson; Dan Henningson; Stefan Ivanell; Martin O. L. Hansen; KTH; []
    Nyckelord :Actuator disc method; Actuator line method; Blade element momentum method; Wind turbine wake; Wake interaction; CFD; LES; EllipSys3D;

    Sammanfattning : In the present thesis the wake flow behind wind turbines is analyzed numerically using large-eddy simulations. The wind turbine rotors are modeled by using either the actuator disc method or the actuator line method in which the blades are represented by body forces computed with airfoil data. LÄS MER

  2. 17. Distribution of expected utility in second-order decision analysis

    Författare :David Sundgren; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beslutsanalys; andra ordningens fördelningar; förväntad nytta; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : In decision analysis maximising the expected utility is an often used approach in choosing the optimal alternative. But when probabilities and utilities are vague or imprecise expected utility is fraught with complications. LÄS MER

  3. 18. Distribution of expected utility in second-order decision analysis

    Författare :David Sundgren; Love Ekenberg; Johan Thorbjörnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : In explicatione consiliorum, maxima facere communis utilitas saepe trita ratio deligendi meliorem optionem est. Verum si probabilitates et utilitates incertae vel dubiae sint, communis utilitas perturbationes affert. LÄS MER

  4. 19. The market impact of short-sale constraints

    Författare :Roland Nilsson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The thesis addresses two areas of research within financial economics: empirical asset pricing and the borderline area between finance and economics with emphasis on econometrical methods. The empirical asset pricing section considers the effects of short-sale constraints on both the stock market as well as the derivatives market. LÄS MER

  5. 20. Across the drip-line and back: examining 16B

    Författare :Ronja Thies; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analysis; Simulations; FAIR; Unbound Nuclei; GSI; Calibrations; Radioactive Beams; R3B; Neutron-dripline;

    Sammanfattning : Until today, after about one century of research, the atomic nucleus, a basic building block of nature, is still a fascinating puzzle. The field of nuclear physics strives for a better understanding employing both experimental and theoretical efforts. LÄS MER
