11. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts
Sammanfattning : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. LÄS MER
12. Characterization and analysis of the astrometric errors in the global astrometric solution for Gaia
Sammanfattning : The space astrometry mission Gaia, planned for launch in 2013 by the European Space Agency (ESA), will provide the most comprehensive and accurate catalogue of astrometric data for galactic and astrophysical research in the coming decades. It will observe roughly one billion stars, quasars and other point like objects for which the five astrometric parameters (position, parallax and proper motion) will be determined. LÄS MER
13. Photon Upconversion in Heavily Doped Semiconductors
Sammanfattning : In this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. LÄS MER
14. Measurement and Application of Multidirectional Mobilities
Sammanfattning : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

15. Numerical Methods for Geometric Vision: From Minimal to Large Scale Problems
Sammanfattning : This thesis presents a number of results and algorithms for the numerical solution of problems in geometric computer vision. In geometric computer vision one tries to extract geometric information about the world and the observer from a sequence of images. LÄS MER
