11. Ions colliding with molecules and molecular clusters : fragmentation and growth processes
Sammanfattning : In this work we will discuss fragmentation and molecular growth processes in collisions of Polycyclic Aromatic Hydrocarbon (PAH) molecules, fullerenes, or their clusters with atoms or atomic ions. Simple collision models as well as molecular structure calculations are used to aid the interpretations of the present and other experimental results. LÄS MER
12. Spectroscopic and kinetic studies of atmospheric oxygen emissions
Sammanfattning : The terrestrial night sky spectrum Is dominated by emission features related to oxygen photochemistry. Photodissociation of molecular oxygen, the second most abundant atmospheric constituent Is the most efficient channel for converting solar electromagnetic radiation into chemical energy. LÄS MER
13. On two methods for identifying dynamic errors-in-variables systems
Sammanfattning : Identification of dynamic errors-in-variables systems, where both inputs and outputs are affected by errors (measurement noises), is a fundamental problem of great interest in many areas, such as process control, econometrics, astronomical data reduction, image processing, etc. This field has received increased attention within several decades.

14. Optically poled fibers for electro-optic applications
Sammanfattning : The work presented in this thesis shows the development of optically poleddevices for use in electro-optic experiments. In the form of papers published,it describes three optical poling methods: green light poling (Paper I), poling with a UV lamp (Paper II), and corona discharge poling (Paper V). LÄS MER
15. Model-based control and monitoring of the flotation process
Sammanfattning : In the mineral processing industry, flotation constitutes the most important technique for extraction of the valuable minerals from the ore. This process involves both chemical and physical parts, the theory of which are not yet completely understood. LÄS MER
