1. Arnold-type invariants of curves and wave fronts on surfaces
Abstract : This thesis is devoted to the study of invariants of generic curves and wave fronts on surfaces. The invariants J± and St were axiomatically defined by Arnold as numerical characteristics of generic curves (immersions of the circle)on ℝ2 he introduced J± in the case of generic planar wave fronts.

3. Water in and on ionic materials : Structure, energetics, and vibrations
Abstract : Many chemical and physical phenomena in nature, in industrial processes, and in our daily lives take place at water/solid interfaces. The aim of this thesis is to further our knowledge of such processes at a molecular level. READ MORE

4. Lubricants influence on wear in sharp rail curves
Abstract : Rail lubrication in curves was widely introduced in Sweden during the 1970’s due to the high wear rate of gauge faces in sharp curves. The first tests performed in Sweden showed that lubrication decreased wear rates by roughly 10 times. Based upon these results, the Swedish track system was equipped with wayside lubricators called Clicomatic. READ MORE

5. Invariancy Methods for Points, Curves and Surfaces in Computational Vision
Abstract : Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. READ MORE
