  4. 22. Backstepping and control allocation with applications to flight control

    Author : Ola Härkegård; Torkel Glad; Marc Bodson; Linköpings universitet; []
    Keywords : backstepping; control allocation; flight control; control theory; nonlinear control; reglerteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis we study a number of nonlinear control problems motivated by their appearance in flight control. The results are presented in a general framework and can also be applied to other areas. The two main topics are backstepping and control allocation. READ MORE

  5. 23. Stopover behaviour in migratory songbirds: timing, orientation and departures

    Author : Sissel Sjöberg; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flight duration; orientation; departure timing; stopover behaviour; stopover duration; flight behaviour; reverse migration; route choice; compass calibration; passerines; Bird migration;

    Abstract : Songbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds.

  6. 24. Analysis of Dynamic Flight Loads

    Author : Natascha Jansson; Ulf Ringertz; David Eller; Peter Linde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the determination of loads on an aircraft struc- ture during flight. The focus is on flight conditions where the loads are significantly time-dependent. Analysis of flight loads is primarily motivated to ensure that structural failure is avoided. READ MORE

  7. 25. There and Back Again - nocturnal migratory behaviour of birds during spring and autumn

    Author : Håkan Karlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; migration; seasons; flight; orientation; navigation; behaviour; strategies; birds; nocturnal;

    Abstract : This dissertation explores the migratory behaviour of nocturnally migrating passerines and common swifts (Apus apus). Birds passing Lund (southern Sweden) and Abisko (northernmost Scandinavia) where sampled using tracking radar. The aim has been to investigate potential diverging strategies between spring and autumn migration. READ MORE
