1. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure
Abstract : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. READ MORE

3. Recursive Methods in Urn Models and First-Passage Percolation
Abstract : This PhD thesis consists of a summary and four papers which deal with stochastic approximation algorithms and first-passage percolation. Paper I deals with the a.s. limiting properties of bounded stochastic approximation algorithms in relation to the equilibrium points of the drift function. READ MORE

4. On the Structure and Dynamics of Polyelectrolyte Gel Systems and Gel-surfactant Complexes
Abstract : This thesis describes the results of experimental work on polyelectrolyte gels and their interaction with oppositely charged surfactants, and presents two new algorithms applicable to the simulation of colloid and polymer systems.The model systems investigated were crosslinked poly(acrylate) (PA) and poly(styrene sulphonate) (PSS), and the surfactant was dodecyl trimethylammonium bromide (DoTAB).

5. Dissolution and Release Behavior of Swellable Matrix Tablets: Influence of the solubility and dissolution rate enhancement of model substance
Abstract : Tablets exhibiting extended drug release have in many therapeutical applications shown both compliance and clinical advantages. One way of achieving extended drug release from a tablet is by employing the concept of swellable matrices. READ MORE
