1. Combinatorial Considerations on Two Models from Statistical Mechanics
Sammanfattning : Interactions between combinatorics and statistical mechanics have provided many fruitful insights in both fields. A compelling example is Kuperberg’s solution to the alternating sign matrix conjecture, and its following generalisations. LÄS MER
2. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions
Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER
3. Bonded Particle Model for Jointed Rock Mass
Sammanfattning : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. LÄS MER
4. Relativistic particle mechanics : a hamiltonian approach
Sammanfattning : This study is devoted to certain fundamental problems within theoretical physics. The aim is to show that there exists a consistent Poincare invariant Hamiltonian formalism describing interactions between any number of discrete particles forming an isolated (in general spinning) system. No fields or potentials are needed for the description. LÄS MER
5. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study
Sammanfattning : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique. LÄS MER
