  1. 1. Numerical computations of wind turbine wakes and wake interaction

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Karl Nilsson; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : When wind turbines are placed in farms, wake effects reduce the overall power production. Also, turbine loads are significantly increased since turbulence levels are high within the wake flow. READ MORE

  2. 2. Numerical computations of wind turbine wakes and wake interaction Optimization and control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Karl Nilsson; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Actuator disc method; Actuator line method; Blade element momentum method; Wind turbine wake; Wake interaction; CFD; LES; EllipSys3D;

    Abstract : 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. READ MORE

  3. 3. Hip Revision Surgery Identification of Genetic Markers and Evaluation of Novel Treatment Strategies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Brüggemann; Nils Hailer; Hans Mallmin; Karl Michaëlsson; Olle Nilsson; Per Wretenberg; [2020]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Total hip arthroplasty (THA) is, despite its overall good outcome, for some patients followed by hip revision surgery. This seems in parts to be because of genetic susceptibility to revision surgery. The most common reason for revision surgery is aseptic loosening followed by periprosthetic joint infection and dislocation. READ MORE

  4. 4. Kin, Friends and Unfriends A Study of the Axelsson Tott Network during the Period of the Kalmar Union

    University dissertation from Växjö : Linnaeus University Press

    Author : Margaret Wallace Nilsson; Linnéuniversitetet.; [2019]
    Keywords : HUMANIORA; HUMANITIES; Late Middle Age; res publica; female networks; Ivar Axelsson; Magdalena Karlsdotter; Karl Knutsson; Christian I; Sten Sture; state formation; factionalism.; Historia; History;

    Abstract : The Dano-Swedish Axelsson Totts created one of the most influential family networks of the Kalmar Union. The Union was not only a political construction created by Queen Margaret, it was an important geographic area for inter-Nordic trade and dynastic contacts. READ MORE

  5. 5. The Money of Monarchs : The Importance of Non-Tax Revenue for Autocratic Rule in Early Modern Sweden

    University dissertation from Lund University

    Author : Klas Nilsson; [2017]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; revenue; autocracy; regime change; fiscal sociology; public finance; state-building; Sweden; Early Modern Europe; Rentier State; royal power; statsinkomster; statsstyre; politisk utveckling; Rentier State; Rentierism; skattesystem; tidigmodern statsbildning; Sverige; europeisk historia;

    Abstract : According to a venerable argument about the formation of political regimes in historical Europe, taxation goes hand in hand with representation, as financial needs forced rulers to trade rights for revenue. In this dissertation I explore the reverse assumption, asking whether it is the case that non-taxation went hand in hand with non-representation? I argue that early modern rulers who had access to what I conceptualize as ‘proprietary revenue’—including profits from landownership, natural resource extraction, state-owned enterprise, and colonial plunder—could use such revenue to concentrate political authority in their own hands and rule as autocrats.
