16. High Order Finite Difference Methods with Artificial Boundary Treatment in Quantum Dynamics
Abstract : The investigation of the dynamics of chemical reactions, both from the theoretical and experimental side, has drawn an increasing interest since Ahmed H. Zewail was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry. READ MORE

17. Mass Conserving Simulations of Two Phase Flow
Abstract : Consider a mixture of two immiscible, incompressible fluids e.g. oil and water. Since the fluids do not mix, an interface between the two fluids will form and move in time. READ MORE

18. Uncertainty Quantification and Numerical Methods for Conservation Laws
Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets. READ MORE

19. Application of Uncertainty Quantification Techniques to Studies of Wall-Bounded Turbulent Flows
Abstract : Wall-bounded turbulent flows occur in many engineering applications. The quantities of interest (QoIs) of these flows can be accurately obtained through experimental measurements and scale-resolving numerical approaches, such as large eddy simulation (LES). READ MORE

20. Aspects of viscous shocks
Abstract : This thesis consists of an introduction and five papers concerning different numerical and mathematical aspects of viscous shocks. Hyperbolic conservation laws are used to model wave motion and advect- ive transport in a variety of physical applications. READ MORE
