  1. 1. : Inverkan av släntnära portryck på släntstabilitet : En känslighetsanalys av siltslänter längs Ångermanälven

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Katia Calming; Myrna Öttenius; [2022]
    Nyckelord :Silt; slope stability; pore water pressure; SLOPE W; Ångermanälven; sensitivity analysis;

    Sammanfattning : The stability of natural slopes is goverened by many factors, one of which is the porewater pressure. In this study, a sensitivity analysis has been conducted in GeostudioSLOPE/W to investigate the impact of near-surface pore water pressure on thefactor of safety i silt slopes. LÄS MER

  3. 2. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Amir Avdic; Kishore-Babu Vejendla; [2022]
    Nyckelord :viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

    Sammanfattning : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. LÄS MER

  4. 3. Modellförsök avseende bergspänningars betydelse för spännvidd av valv

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Minna Larsson; Klara Skoog; [2020]
    Nyckelord :arch; arching; span of arch; rock stress; rock reinforcement; rock bolt; valv; valvbildning; spännvidd; bergspänning; bergförstärkning; bergbult;

    Sammanfattning : Tunnels and anthropogenic underground cavities are a very natural part of our everyday modern life. Especially in larger cities such as Stockholm where the infrastructure reaches far above ground level as well as deep below the surface. LÄS MER

  5. 4. Concept Study and Design ofFloating Offshore Wind TurbineSupport Structure

    Master-uppsats, KTH/Marina system

    Författare :Markus Johannessen; [2018]
    Nyckelord :;

    Sammanfattning : There is a need for renewable energy sources that can replace the non-renewable energy sourcesthat we use today. This is on the agenda as one of the United Nations sustainable developmentgoals. Embracing new technologies is addressed as one of the ways of achieving aordable,reliable, sustainable and modern energy for all. LÄS MER

  7. 5. Optimization of the hull shape of a specialized vessel used to deploy wave energy converters

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Elektricitetslära

    Författare :Simon Larsson; [2016]
    Nyckelord :Hydrostatic stability; Stability; Specialized vessel; Deployment of wave Energy Converters; Deployment; Solidworks; Ansys Aqwa; Structural analysis; Stability analysis; Optimization;

    Sammanfattning : In this study, the initial hydrostatic stability, the hydrostatic stability and the structure realibility of three different barge-shaped vessels is simulated and evaluated in order to see which of the vessels would be the most optimal to use for deployment of wave energy converters, WECs. The vessels differ in their hull type: Bulbous-bow hull vessel, Barge hull vessel and Modified-barge hull vessel. LÄS MER
