  1. 1. A space-time shape for easier spatiotemporal visualization in traffic networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :David Smeds; [2024]
    Nyckelord :;

    Sammanfattning : Modern big data systems are enabling new possibilities that never were thought possible in the past. The ability to gather massive data on an individual level has made fields like space-time geography bloom in the latest decennia. The usage of shapes in a 3D space allows us to visualize certain phenomena over time. LÄS MER

  3. 2. Diving Deep: Seabird foraging tactics and local prey field

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Elin Andersson Sjöholm; [2024]
    Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER

  4. 3. Navigating the Waves of Conservation: Spatiotemporal Patterns in Harbour Porpoise Strandings in Swedish Waters

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Vigge Ulfsson; [2024]
    Nyckelord :Strandings; spatiotemporal patterns; harbour porpoise;

    Sammanfattning : Harbour porpoises (Phocoena phocoena) are the only cetacean residents found year-round in Swedish waters. Since in situ monitoring of cetaceans can be difficult, invasive and often costly, strandings can be used as a cost-effective alternative to continuously collect data on these elusive animals.

  5. 4. Compression of Sequential Voxel Data for Sequence-based Animation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Filip Antonijevic; [2023-10-23]
    Nyckelord :voxel; octree; grid; compression; animation; spatiotemporal; sorting; reordering; DXT; HSV;

    Sammanfattning : This thesis presents a method for lossy compression of voxel data in an animation sequence. Uncompressed voxel animation can become very memory intensive and therefore need a more efficient method to store and render such data. LÄS MER

  7. 5. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER
