  1. 1. In the wake of a bird - Quantifying aerodynamic performance of avian flight

    University dissertation from Department of Biology, Lund University

    Author : Marco Klein Heerenbrink; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; flight performance; gliding; powered flight; wing morphology; aerodynamics; biomechanics; birds; jackdaw; Corvus monedula; wind tunnel; PIV;

    Abstract : Popular Abstract in English Insects, birds, bats and pterosaurs have all evolved the ability to fly, even though it requires a lot of energy. The advantage is obvious: one can move about vertically, to go where others cannot, find and access distant food sources or escape your predators. READ MORE

  2. 2. Performance Studies and Star Tracking for PoGOLite

    University dissertation from Stockholm : KTH

    Author : Cecilia Marini Bettolo; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polarization; pulsars; x-ray; PoGOLite; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik;

    Abstract : PoGOLite is a balloon-borne experiment, which will study polarized soft γ-ray emissionfrom astrophysical targets in the 25-80 keV energy range by applying well-typephoswich detector technology. Polarized γ-rays are expected from a wide variety of sources including rotation-powered pulsars, accreting black holes and neutron stars,and jet-dominated active galaxies. READ MORE

  3. 3. On stability, transition and turbulence in three-dimensional boundary-layer flows

    University dissertation from KTH Royal Institute of Technology

    Author : Seyed Mohammd Hosseini; KTH.; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional bound- ary layers; crossflow instability; roughness control; freestream turbulence; sec- ondary instability; transition; turbulence;

    Abstract : A lot has changed since that day on December 17, 1903 when the Wright brothers made the first powered manned flight. Even though the concepts behind flying are unaltered, appearance of stat-of-the-art modern aircrafts has undergone a massive evolution. READ MORE
