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

    Författare :Per Henningsson; Biologiska institutionen; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 7. Ground Object Recognition using Laser Radar Data : Geometric Fitting, Performance Analysis, and Applications

    Författare :Christna Grönwall; Fredrik Gustafsson; Kalle Åström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser radar; object detection; object recognition; performance; least squares; ICP; Cramér-Rao; Signal processing; Signalbehandling;

    Sammanfattning : This thesis concerns detection and recognition of ground object using data from laser radar systems. Typical ground objects are vehicles and land mines. For these objects, the orientation and articulation are unknown. The objects are placed in natural or urban areas where the background is unstructured and complex. LÄS MER

  4. 8. Flight Simulator Training : Assessing the Potential

    Författare :Staffan Magnusson Nählinder; Kjell Ohlsson; Nils Dahlbäck; Erland Svensson; Ken R. Boff; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Work sciences and ergonomics; Arbetsvetenskap och ergonomi;

    Sammanfattning : Mental workload is an important concept and has been proven to be a precursor to situation awareness and operative performance. This thesis describes methods to measure mental workload through self-ratings and psychophysiological measurements. LÄS MER

  5. 9. Digital block transmission and time-of-flight estimation : receiver design and performance analysis

    Författare :Håkan B. Eriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. LÄS MER

  7. 10. Male moth behaviour and perception in pheromone plumes

    Författare :Peter Valeur; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Grapholita molesta; Noctuidae; Lepidoptera; Tortricidae; behaviour; electrophysiology; single cell; flight tunnel; sex pheromone; wind tunnel; radar; flight; pre-exposure; mechanisms of mating disruption; Agrotis segetum; choice test;

    Sammanfattning : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. LÄS MER
