    Nyckelord :konnektivitet; fiskvandring; dammrivning; avsänkning; batymetri; elfiske; biotopkartering; HEC-RAS; hydraulisk modellering; fiskväg; vandringshinder;

    Sammanfattning : I Sverige finns i dagsläget närmare 10 000 dammar i våra vattendrag. Dammar som har varit en viktig del i den svenska historien men som nu utgör ett hot mot att uppsatta miljömål nås. Dammarna fragmenterar effektivt vattendragen då de utgör vandringshinder för fisk och andra vattenlevande organismer. LÄS MER

    Sammanfattning : Hydrofoil-equipped naval vessels are not new. The technique appeared at the beginning of the 20th century and there are still new developments within the field. LÄS MER

  5. 4. Additive Manufacturing Applications for Wind Turbines

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Niklas Wahlström; Oscar Gabrielsson; [2017]
    Nyckelord :Additive Manufacturing; Wind Power Plant; Rotating Union; Additiv Tillverkning; Vindkraftverk; Roterskarv;

    Sammanfattning : Additive manufacturing (AM), also known as 3D-printing is an automated manufacturing process in which the component is built layer upon layer from a predefined 3D computer model. In contrast to conventional manufacturing processes where a vast volume of material is wasted due to machining, AM only uses the material that the component consists of. LÄS MER
