  1. 1. Run-Up Transient Analysis for Salient Pole Wound Field Synchronous Motors : Field winding and power electronics implications for a smoother and cooler asynchronous start

    Författare :Roberto Felicetti; Urban Lundin; Andreas Binder; Uppsala universitet; []
    Nyckelord :apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency; asynchronous start; run-up; torque ripple; reluctance torque; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Salient Pole Wound Field Synchronous Machines have better efficiency at full load than asynchronous machines of the same capability. Moreover, where asynchronous machines need inherently to draw a magnetizing current from the grid, Salient Pole Wound Field Synchronous Machines can work efficiently at unity power factor. LÄS MER

  3. 2. Causal Inference: Applications in Education, Violence, and the Scientific Process

    Författare :Felix Schafmeister; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of five self-contained chapters. In chapter 1, I analyze how replications affect how underlying studies are cited. My results provide no evidence that citations changed in response to either successful or failed replications, with potentially worrying implications for the self-corrective ability of the scientific process.

  4. 3. The Sellable Self : Exploring endurance running as an extraordinary consumption experience

    Författare :Carys Egan-Wyer; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extraordinary experience; Neoliberalism; Governmentality; Consumer culture theory; Endurance running; Discourse; Foucault; Vocabularies of motive;

    Sammanfattning : In this thesis, I critically explore the ways in which people consume extraordinary experiences and what this can tell us about contemporary society. My findings question the idea that extraordinary experiences are an escape from the demands of everyday life. LÄS MER

  5. 4. Välfärdsstaten, sociala rättigheter och invandrarnas maktresurser : en jämförande studie om äldre invandrare från Mellanöstern i Stockholm, London och Berlin

    Författare :Welat Songur; Ingegärd Municio; Daine Sainsbury; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Äldre invandrare; Sverige; Storbritannien; Tyskland; Välfärdsstaten; statsvetenskap; Political Science;

    Sammanfattning : The subject of the dissertation is formal and substantive rights. It focuses on the question of the role of different types of welfare states in the social rights of elderly immigrants and their power resources. Despite changes that have occurred during the post-war period, the situation of immigrants can nonetheless be problematic. LÄS MER

  7. 5. Upscaling, Training, Commoning

    Sammanfattning : When on September 15, 2008 the financial conglomerate Lehman Brothers files for bankruptcy – and with that ‘officially’ sparks the international financial crisis – still few would anticipate the invasive effect this crisis would come to have on the professional and personal life of many across the world. Today, it’s implosion remains a mere ‘blip’ in the universe of events that followed. LÄS MER
