  2. 1. Birds in the Flow: Flight Mechanics, Wake Dynamics and Flight Performance

    Author : Mikael Rosén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Eleonora s falcon.; hunting; optimum wingspan; tail posture; wingbeat kinematics; wake topology; DPIV; flight performance; wake dynamics; flight mechanics; wind tunnel; Flight; bird;

    Abstract : I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. READ MORE

  4. 2. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts

    Author : Per Henningsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apus apus; aerodynamics; animal flight; kinematics; vortex wake; digital particle image velocimetry; DPIV; common swift; tracking radar; wind tunnel; migration; roosting flight;

    Abstract : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. READ MORE

  5. 3. Power and Wake Dynamics of Hawkmoth Flight

    Author : Kajsa Warfvinge; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect flight; Aerodynamics; Wind tunnel; Particle Image Velocimetry PIV .; tomo-PIV; Power; Manduca sexta; Macroglossum stellatarum; Hawkmoth;

    Abstract : 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. READ MORE

  6. 4. Dynamics in meetings : on leadership and followership in ordinary meetings in different organizations

    Author : Kjell Granström; Karin Aronsson-Ottosson; Per Linell; Linköpings universitet; []
    Keywords : group processes; leadership; followership; decision-making; the school as an organization; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : A method for analyzing interactional dynamics in regular meetings and sessions was developed on the basis of Bion's (1961) basic-assumption model. This model postulates that members in groups frequently take part in collective defence activities which prevent the group from carrying out the tasks assigned to them. READ MORE
