    Sammanfattning : Wave power conversion is one type of renewable electricity generation. Within wave power, there are many different concepts, whereof some utilizes linear generators for converting the energy in the ocean waves into electricity. LÄS MER

  4. 13. Power transfer in the air gap of linear generators for wave power

    Författare :Anna E. Frost; Mats Leijon; Sandra Eriksson; Irina Temiz; Thomas Rylander; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear generator; Wave Power; Air gap; Poynting s theorem; Partial stator-translator overlap; Linear electrical machines; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : An increased need for electric energy and share of renewable energy is important for a more sustainable future, to which wave power can contribute. Some concepts for wave power use linear generators, and the studies presented here focus on the power transfer and forces in the air gap of linear generators. LÄS MER

  5. 14. Laboratory Investigations of Frost Action Mechanisms in Soils

    Författare :Deniz Dagli; Jan Laue; Tommy Edeskär; Lukas Arenson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold Regions Soil Mechanics; Frost Action; Frost Depth; Frost Heave; Heat Flow in Soils; Ice Lens Formation; Image Analysis; Laboratory Freezing Test; Soil Mechanics; Geoteknik;

    Sammanfattning : Phase change of the water in the soil skeleton under cold climate conditions (also known as frost action in soils) affects soil properties and can be responsible for serious alterations in a soil body; causing damages (due to the volumetric expansion known as frost heave) to structures on or below the ground surface such as foundations, roads, railways, retaining walls and pipelines, etc. In order to improve the current design methods for roads against frost action, the Swedish Transport Administration (Trafikverket) has initiated a research program.
