1. 21. Model Predictive Control in Flight Control Design : Stability and Reference Tracking

   Författare :Daniel Simon; Johan Löfberg; Sébastien Gros; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control;

   Sammanfattning : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. LÄS MER

3. 22. Time of Flight Estimation for Radio Network Positioning

   Författare :Kamiar Radnosrati; Fredrik Gustafsson; Gustaf Hendeby; Simon Godsill; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Trilateration is the mathematical theory of computing the intersection of circles. These circles may be obtained by time of flight (ToF) measurements in radio systems, as well as laser, radar and sonar systems. A first purpose of this thesis is to survey recent efforts in the area and their potential for localization. LÄS MER

   Sammanfattning : Additive Manufacturing (AM) for metals includes is a group of production methodst hat use a layer-by-layer approach to directly manufacture final parts. In recent years, the production rate and material quality of additive manufactured materials have improved rapidly which has gained increased interest from the industry to use AM not only for prototyping, but for serial production.

5. 24. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

   Författare :Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

   Sammanfattning : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). LÄS MER

7. 25. Fuel and fly: adaptations to endurance exercise in migrating birds

   Författare :Anders Kvist; Bröstcancer-genetik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water balance; flight power; phenotypic flexibility; energy assimilation; basal metabolism; Animal ecology; Djurekologi;

   Sammanfattning : Birds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. LÄS MER
