  2. 2. Power and Wake Dynamics of Hawkmoth Flight

    Detta är en avhandling från Lund University, Faculty of Science

    Författare :Kajsa Warfvinge; Lund University.; Lunds universitet.; [2019-05-20]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insect flight; Aerodynamics; Wind tunnel; Particle Image Velocimetry PIV .; tomo-PIV; Power; Manduca sexta; Macroglossum stellatarum; Hawkmoth;

    Sammanfattning : Aerodynamic theory states that the power required to fly is related to flight speed with a ∪-shaped curve. This has been shown in vertebrates, but insects have been proposed to have a flat, or J-shaped power curve. LÄS MER

  3. 3. Aerodynamic performance in bat flight

    Detta är en avhandling från Lund University, Faculty of Science, Department of Biology

    Sammanfattning : The dominant part of the research on the “Yûgao” (The Twilight Beauty) story of the Japanese eleventh-century classic the Genji Monogatari (The Tale of Genji) is philological and often excludes a general literary analysis. This story has also been related to Japanese and Chinese literary influences, thereby placing the text in its literary context. LÄS MER

  5. 5. Fuzzy Control for an Unmanned Helicopter

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Bourhane Kadmiry; Linköpings universitet.; Linköpings universitet.; [2002]

    Sammanfattning : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linköping University is the development of an intelligent command and control system, containing vision sensors, which supports the operation of a unmanned air vehicle (UAV) in both semi- and full-autonomy modes. One of the UAV platforms of choice is the APID-MK3 unmanned helicopter, by Scandicraft Systems AB. LÄS MER
