21. Aerosol-Cloud-Precipitation Interactions - Studied using combinations of remote sensing and in-situ data
Sammanfattning : Cloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. LÄS MER
22. Tracking the Wanders of Nature
Sammanfattning : Target tracking is a mature topic with over half a century of mainly military and aviation research. The field has lately expanded into a range of civilian applications due to the development of cheap sensors and improved computational power. LÄS MER
23. Hubble Space Telescope Spectroscopy of Eta Carinae and Chi Lupi
Sammanfattning : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. LÄS MER
24. Methods of Multi-Conjugate Adaptive Optics for Astronomy
Sammanfattning : This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future.

25. Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data
Sammanfattning : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. LÄS MER
