  1. 1. Marine Current Energy Conversion

    Författare :Staffan Lundin; Mats Leijon; AbuBakr S. Bahaj; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marine current energy; renewable energy; turbine; energy conversion; wake; Söderfors; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Marine currents, i.e. water currents in oceans and rivers, constitute a large renewable energy resource. This thesis presents research done on the subject of marine current energy conversion in a broad sense. LÄS MER

  3. 2. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator

    Författare :Oskar Danielsson; Mats Leijon; Göran Engdahl; Uppsala universitet; []
    Nyckelord :Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

    Sammanfattning : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. LÄS MER

  4. 3. Alkali Release and Effects on Biomass Thermal Conversion Processes

    Författare :Yaxin Ge; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-conversion; Alkali; Biomass; bed material; thermal conversion; online measurements;

    Sammanfattning : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.

    Författare :Anna Månsson; Avdelningen för konsthistoria och visuella studier; []
    Nyckelord :HUMANIORA; HUMANITIES; ethnology; Cultural anthropology; person-centered ethnography; psychological anthropology; Muslims in the U.S.; Muslims in Sweden; Islam in the West; conversion narrative; conversion to Islam; Muslim identity; identity-making; cognitive models; Kulturantropologi; etnologi; Non-Christian religions; Världsreligioner ej kristendom ;

    Sammanfattning : "Becoming Muslim: Meanings of Conversion to Islam" is an ethnographic study analyzing the identity-making of female Muslim converts. It is based on eighteen in-depth interviews with six women in Sweden and three women in the U.S. LÄS MER

  7. 5. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Författare :Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Sammanfattning : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. LÄS MER
