  1. 6. Directional aggressive pulse sounds in the bottlenose dolphin (Tursiops Truncatus) : technical aspects and social implications

    Författare :Christer Blomqvist; Kathleen Dudzinski; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The ability of dolphins to produce pulse sounds with a bandwidth of up to 150 kHz, has been intensively studied with focus on their sonar capabilities, i.e. the detection, ranging and discrimination of objects of various shapes, textures and material. LÄS MER

  2. 7. Multi-Channel Acquisition and Visualization of the Dolphin Echolocation Beam – Instrumentation Design and Bioacoustic Results

    Författare :Josefin Starkhammar; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Toothed whales (Odontocetes) use echolocation to navigate and find food in dark or murky waters. A wide range of innovative studies has since the 1960:s been used to characterize their echolocation beam and map out their echolocation skills. LÄS MER

  3. 8. Tracking of Animals Using Airborne Cameras

    Författare :Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Kalle Åström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The various elements of a modern target tracking framework are covered. Background theory on pre-processing, modelling and estimation is presented as well as some novel ideas on the topic by the author. In addition, a few applications are posed as target tracking problems for which solutions are gradually constructed as relevant theory is covered. LÄS MER

  4. 9. Tracking the Wanders of Nature

    Författare :Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Hans Driessen; Linköpings universitet; []
