  1. 16. Comparison of electricity production between semi-submersible and spar-buoy floating offshore wind turbines

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Nermina Saracevic; [2018]
    Nyckelord :floating offshore wind turbine; semi-submersible; spar-buoy; six degrees of freedom; platform-rotor interaction; ASHES;

    Sammanfattning : The paper compares electricity production between the semi-submersible and the spar-buoy floating wind turbine systems under normal, stochastic and extreme wind conditions at Utsira Nord site located on the Norwegian continental shelf in the North Sea. The analysis of complex behavior of the floating wind turbine system and the fluid-structure interaction is performed in aero-servo-hydro-elastic code ASHES. LÄS MER

  3. 17. Konceptuell flygplansdesign : Design av stridsflygplan för luftburen satellituppskjutning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Ebba Lindgren; Andreas Baldhagen; [2018]
    Nyckelord :;

    Sammanfattning : Är det möjligt för JAS 39 Gripen E att utföra en luftburen satellituppskjutning? Den frågeställningen har detta projekt undersökt utifrån ett designmässigt likvärdigt stridsflygplan. Det designade flygplanet har tagits fram på konceptuell nivå med satellituppskjutningsuppdraget som utgångsläge. LÄS MER

  4. 18. Otolith morphology of sprat (Sprattus sprattus) along the Swedish west coast

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Francesco Saltalamacchia; [2018]
    Nyckelord :European sprat; Otolith; shape analysis; wavelet;

    Sammanfattning : The population structure of sprat (Sprattus sprattus) in the Swedish Kattegat – Skagerrak has been at present not well investigated, and the boundaries between the management unit in this region and the larger stock occurring in the North Sea are also highly uncertain, posing issues to the successful management of the stock in this area. In this study, variations in otolith shape among several samples from the Swedish west coast, southern North Sea and Norwegian fjords north of Bergen were studied to investigate the effectiveness of shape analysis for characterise the population structure in the study area, and evaluate whether differences could be used to assign individual fish to their origin.

  5. 19. Spatial distribution of persistent organic pollutants (POPs) in sediments contaminated by fiber material from pulp and paper industries

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Gabriel Dupaul; [2018]
    Nyckelord :PCB; DDT; HCB; fiberbank; fiber-rich sediment; sediment; Sweden; Västernorrland; Ångermanälven; Gulf of Bothnia; Baltic sea;

    Sammanfattning : Sweden has had a long history of forestry activities together with pulp and paper operations. Historical discharges of organic-rich wastewater from pulp and paper factories have resulted in formation of large fiberbanks on the seafloor, which lately have been found to be contaminated with persistent organic pollutants (POPs).

  7. 20. The Sedimentological Distribution of Upper Brent, Oseberg field, North Sea

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Mandana Farvardini; [2017]
    Nyckelord :Sedimentology;

    Sammanfattning : The Oseberg hydrocarbon field is located in the northern North Sea sedimentary basin (61-62° N) on the eastern flank of the Viking Graben and is bounded to the east by the Horda Platform and the Øygarden Fault Complex (ØFC). The field is covering up most parts of block 30/6 and 30/9 on the Norwegian Continental Shelf (NOCS) but also minor parts of blocks 30/5, 30/8 and 30/12. LÄS MER
