  1. 1. Analys av magnetfält kring högspänd luftledning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Marcus Blom; [2020]
    Nyckelord :Kraftledning; magnetfält; luftledning; Biot-Savart;

    Sammanfattning : The digitalization of our community, robotization of our industry and electrification of our transports leads to an increasing demand of electric power, which relies on a strong and reliable grid. In order to continuously be able to deliver stable and qualitative electric power all over Sweden the grid needs to be expanded. LÄS MER

  3. 2. Modelling of the vibrational behavior of housing plates filled with fibrous material

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Da Cao; [2020]
    Nyckelord :;

    Sammanfattning : Silencers are used in vehicles to reduce the noise in the engine system. However,silencers themselves may produce break-out noise due to the interactionwith the exhaust gas ow and structure. In this Master thesis project, thenumerical simulation of vibrational behavior of housing plates of silencers isdeveloped. LÄS MER

  4. 3. A simplified vortex method for wind turbine simulation

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Sandro Malusa; [2019]
    Nyckelord :Wind turbine; Vortex model; Numerical wake model; Vortex sheet; Vortex filament; Tjaereborg; Biot-Savart law; Iterative method;

    Sammanfattning : A new vortex model for wind turbines was developed in order to evaluate the loads at the blades and other important characteristics of interest for the wind industry such as power and thrust coefficients. Nowadays, the calculation of these quantaties is done in a reliable and precise manner with LES simulation using actuator line or actuator disk models. LÄS MER

  7. 5. ”Human uses carefully managed” : A critical discourse analysis of the Chagos Marine Protected Area

    Kandidat-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Axel Hallgren; [2018]
    Nyckelord :large-scale marine protected areas; political ecology; biopolitics; human-nature relationship; territorialization; critical discourse analysis; chagos marine protected area;

    Sammanfattning : The large marine protected area (MPA) declared in 2010 around the Chagos Archipelago, also known as the British Indian Ocean Territory (BIOT), has led to a conflict in the thick of environmental protection, colonialism, sovereignty claims, and the human rights dispute of the Chagossian people that once were exiled from the islands in the 1970s. By applying a Foucauldian inspired critical discourse analysis, this study interprets and examines how the nature/human relationship was portrayed during and after the creation of the Chagos MPA.
