1. The Plasma Contact System : New Functional Insights from a Hemostatic and Thrombotic Perspective
Abstract : The physiological role of the plasma contact system still remains a partial enigma. The aim of the presented work was to expand our understanding of the plasma contact system, focusing on its physiological activation and function, principally from a hemostatic perspective. It also explored contact system activation under pathological conditions. READ MORE

2. Accuracy, efficiency and robustness for rigid particle simulations in Stokes flow
Abstract : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. READ MORE

3. Wavelet Galerkin methods for elastic multibody systems with unilateral contact constraints
Abstract : In this thesis we investigate the applicability of wavelets to simulate the time behavior of elastic multibody systems (MBS) with contact constraints. For this end, a wavelet element method (WEM) was implemented, exploiting the special structure of the coupled ODE/PDE equations that govern elastic MBS. READ MORE

4. Speciation and Metabolic rate : Insights from an avian hybrid zone
Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE

5. Wheel-rail contact modelling in vehicle dynamics simulation
Abstract : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. READ MORE
