  1. 1. Design Optimization of Savonius Wind Turbine using CFD Simulations

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Vatsalkumar Manavar; [2023]
    Nyckelord :Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

    Sammanfattning : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

  3. 2. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Duncan Jones; [2023]
    Nyckelord :Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  4. 3. Compression of Large-Scale Aerial Imagery : Exploring Set Redundancy Methods

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Datavetenskap

    Författare :Solvej Lüdeking; [2023]
    Nyckelord :Set redundancy; image compression; aerial imagery;

    Sammanfattning : Compression of data has been historically always important; more data is gettingproduced and therefore has to be stored. While hardware technology advances,compression should be a must to reduce storage occupied and to keep the data intransmission as small as possible. LÄS MER

  5. 4. ATLAS DATABASES OF HUMAN BRAIN ANATOMY: QUALITATIVE AND QUANTITATIVE COMPARISON

    Master-uppsats,

    Författare :Amanda Philipsson Franzén; [2021-01-11]
    Nyckelord :Medical physics; Brain atlas concordance problem; Quantitative comparison; Qualitative comparison; Hammersmith; 2012 MICCAI Multi-Atlas Labelling Challenge Data;

    Sammanfattning : The purpose of this study was to quantitatively and qualitatively compare the two brain atlases databases, Hammersmith and 2012 MICCAI Multi-Atlas Labelling Challenge data, by developing a quantitative method. Theory Anatomical atlases of the human brain provide reference information about its structure. LÄS MER

  7. 5. Carbon Abundance in the Milky Way Galaxy

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Calum Kvernes Macpherson; [2021]
    Nyckelord :Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. LÄS MER
