1. Photoelectron Spectroscopy on Atoms, Molecules and Clusters : The Geometric and Electronic Structure Studied by Synchrotron Radiation and Lasers
Abstract : Atoms, molecules and clusters all constitute building blocks of macroscopic matter. Therefore, understanding the electronic and geometrical properties of such systems is the key to understanding the properties of solid state objects. READ MORE

2. Solutions and their ambiguities for structure and motion problems
Abstract : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. READ MORE

3. Approximation Algorithms for Geometric Networks
Abstract : The main contribution of this thesis is approximation algorithms for several computational geometry problems. The underlying structure for most of the problems studied is a geometric network. READ MORE

4. Structure, Bonding and Chemistry of Water and Hydroxyl on Transition Metal Surfaces
Abstract : The structure, bonding and chemistry of water and hydroxyl on metal surfaces are presented. Synchrotron based x-ray photoelectron- and x-ray absorption spectroscopy along with density functional theory calculations mainly form the basis of the results. READ MORE

5. Electronic and Geometric Structure of Phthalocyanines on Metals
Abstract : Adsorption of monolayers and multilayers of metal-free and metal phthalocyanines molecules on metal surfaces has been investigated using complementary microscopic and synchrotron-based spectroscopic techniques. It was observed by STM measurements that at monolayer coverage the adsorption direction of the metal-free phthalocyanine molecules with respect to the gold surface vary as a function of temperature, i.
