11. Mathematical Modelling of Light Scattering in Paper and Print
Sammanfattning : A problem formulation and a solution method are outlined for the radiative transfer problem in vertically inhomogeneous scattering and absorbing media, using discrete ordinate model geometry. The treatment spans from the physical problem via a continuous formulation, a discretization and a numerical analysis, to an implementation with performance evaluation and application to real-world problems.

12. Flexibel utbildning i gymnasieskolan : Utvidgade klassrum och minskad transaktionell distans
Sammanfattning : During the 1990s radical reforms were effected in the Swedish school, at the same time as computerizing and the use of Internet increased considerably. The thesis discusses the dynamics and uncertainty that arise when changes and new technique appear in school and shall be combined with already ongoing works of change. LÄS MER
13. Learning in visual art practice
Sammanfattning : The object of research in this thesis is learning within the context of a practice-based Master of Fine Arts program in visual art in Sweden. Research on learning in visual art practice within higher education is sparse, and we know little of the students’ learning processes. LÄS MER
14. Theoretical and Computational Studies on the Physics of Applied Magnetism : Magnetocrystalline Anisotropy of Transition Metal Magnets and Magnetic Effects in Elastic Electron Scattering
Sammanfattning : In this thesis, two selected topics in magnetism are studied using theoretical modelling and computational methods. The first of these is the magnetocrystalline anisotropy energy (MAE) of transition metal based magnets. In particular, ways of finding 3d transition metal based materials with large MAE are considered. LÄS MER
15. Theoretical Magnet Design : From the electronic structure of solid matter to new permanent magnets
Sammanfattning : A good permanent magnet should possess a large saturation magnetisation (Ms), large mag- netocrystalline anisotropy energy (MAE) and a high Curie temperature (TC). A difficult but important challenge to overcome for a sustainable permanent magnet industry is to find novel magnetic materials, exhibiting a large MAE, without the use of scarcely available elements such as rare-earth metals.
