1. Stability of the free-surface problem arising in ice-sheet- and glacier modeling : Numerical investigation and stabilization
Abstract : This thesis consists of two papers dealing with a stabilization method for free-surface flows. The method was initially developed to stabilize mantle-convection simulations, but is in this work extended to ice-sheet- and glacier modeling. READ MORE

2. Stability of tailings dams : focus on numerical modelling
Abstract : Upstream tailings dams may experience slope stability problems when the rate of raising is too fast. Tailings consolidate slowly due to low hydraulic conductivity. The excess pore pressures can build up due to accelerated rate of raising. READ MORE

3. Stability of Low-Frequency AC Railways : Models and Transient Stability
Abstract : Low-frequency AC railway grids are unique in the sense that a only few countries around the world uses them, still however, they are an important parts of their countries infrastructures. Due to the usage of a dierent frequency than the public grid of the country, conversion of frequency is needed for the interconnection. READ MORE

4. Heat and Mass Transfer in Built Structures - Numerical Analyses
Abstract : Heat and mass transport processes are often present simultaneously in built structures in building applications. The emphasis of this thesis is to contribute to knowledge about predicting the effects of combined heat and mass transport in built structures. READ MORE

5. Stable High-Order Finite Difference Methods for Aerodynamics
Abstract : In this thesis, the numerical solution of time-dependent partial differential equations (PDE) is studied. In particular high-order finite difference methods on Summation-by-parts (SBP) form are analysed and applied to model problems as well as the PDEs governing aerodynamics. READ MORE
