  1. 11. Application and Development of the CEASIOM-SUMO-EDGE Suite for Rapid AeroData Assessment of Aircraft Flying Qualities

    Författare :Mengmeng Zhang; Arthur Rizzi; Jesper Oppelstrup; Trevor Birch; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Sammanfattning : In aircraft design, methods for rapid aerodata assessment and data screening at early stages are instrumentalin reducing development cost and first-time-right processes. New efficient tools for the analysis can easethe transition as the traditional and rigidly structured sequential design process gives way to a concurrentmulti-disciplinary process with the compressed time-span required in the competition for market shares.

  3. 12. Tales of the flying earth: The effect of host flyways on the phylogeny of shorebird lice (Phthiraptera: Ischnocera)

    Författare :Daniel Gustafsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parasite; Bird; Lice; Louse; Migration; Evolution; Ecology; Co-evolution; Lunaceps; Shorebirds; Carduiceps; Quadraceps; Revision; Phylogeny; Saemundssonia; Rallicolidae; Charadriiformes; Scolopacidae; Phthiraptera; Philopteridae; Ischnocera; Sandpiper; Flyways; Chewing Lice;

    Sammanfattning : On the wings, bodies, and heads of most birds there are lice. These lice spend their whole lives on their host, with the exception of the few lice that get the opportunity to transfer from one host to another, typically when the hosts come into physical contact with each other.

  5. 14. Families, credit and banks

    Författare :Elena Mattana; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This doctoral thesis consists of three essays: Flying the Nest: Intergenerational Strategic Interaction, Co-residence, and Social Mobility. Southern Europe is characterized by high levels of intergenerational earnings persistence and high levels of co-residence between parents and their offspring. LÄS MER

  7. 15. Feathers by day, membranes by night - Aerodynamic performance in bird and bat flight

    Författare :Florian Muijres; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; animal flight; aerodynamics; vortex wake; actuator disk; flight performance; span efficiency; bird; bat; wind tunnel; PIV; Pied Flycatcher; Glossophaga soricina; Leptonycteris yerbabuenae;

    Sammanfattning : The efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. LÄS MER
