  1. 1. Wave Energy Converters An experimental approach to onshore testing, deployments and offshore monitoring

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Liselotte Ulvgård; Uppsala universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; ocean energy; linear generator; measurements; sensors; point absorber; offshore; PTO; force; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The wave energy converter (WEC) concept developed at Uppsala University consists of a point absorbing buoy, directly connected to a permanent magnet linear generator. Since 2006, over a dozen full scale WECs have been deployed at the Lysekil Research Site, on the west coast of Sweden. LÄS MER

    Detta är en avhandling från Umeå : Umeå University

    Författare :Anteneh Assefa; Umeå universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polychlorinated dibenzo-p-dioxin; polychlorinated dibenzofuran; positive matrix fac- torization; PMF; principal component analysis; PCA; Baltic Sea; sediment core; PCDD F; sources; marine; fish; environmental half-live; peak year; peak level; temporal trend; spatial variation; coastal; offshore; chemical fingerprint; Environmental Science; miljövetenskap;

    Sammanfattning : High levels of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in edible fish in the Baltic Sea have raised health concerns in the Baltic region and the rest of Europe. Thus, there are urgent needs to characterize sources in order to formulate effective mitigation strategies. LÄS MER
