  1. 1. Estimation of state and identification of complex modulus based on measurements om a bar traversed by waves

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lars Hillström; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wave; extensional; flexural; bar; rod; beam; elastic; viscoelastic; complex modulus; non-parametric; parametric; standard deviation; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid Mechanics; hållfasthetslära;

    Sammanfattning : Estimation of state and identification of complex modulus based on measurements on non-uniform rods and beams have been studied theoretically and experimentally. Two principal cases were studied. In the first case, the material properties are fully known and the state at a section is to be estimated. LÄS MER

  3. 3. Size selection of fish in the trap fisheries of the Baltic and Bothnian Seas

    Detta är en avhandling från Umeå : Sveriges Lantbruksuniversitet

    Författare :Mikael Lundin; Carin Magnhagen; Lars Hillström; [2014]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Baltic Sea; Pontoon trap; Bycatch; Size-selection; Selection panel; Grid;

    Sammanfattning : A sustainable fishery in the Baltic Sea requires fishing gear that fishes selectively and at the same time excludes raiding seals. A successful type of trap recently developed in response to the seal problem is the pontoon fish chamber, which significantly decreases damage to gear and catch losses caused by grey seals. LÄS MER
