1. Ab initio Lattice Dynamics : Hydrogen-dense and Other Materials
Abstract : This thesis presents a theoretical study of materials under high pressure using ab initio lattice dynamics based on density functional theory and density functional perturbation theory using both super-cell and linear response approach. Ab initio lattice dynamics using super-cell approach is applied to compare our theoretical predictions with experimental findings. READ MORE

2. Numerical study of dense particle flows under planar shear
Abstract : In this thesis I conducted numerical simulations to study the flow behavior of dense particle flows composed of hard particles under planar shear using the discrete element method. The simulations were carried out in two dimensional systems, where the particles are modelled as circular discs. The discs are non-Brownian and neutrally buoyant. READ MORE

4. Multidimensional MRI of Myocardial Dynamics : Acquisition, Reconstruction and Visualization
Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. READ MORE

5. Excavation in moraine and dense non-cohesive soil : Numerical analysis of soil behavior
Abstract : Excavation and moving of soil are common civil work tasks connected to the construction of buildings, roads and railways. In construction projects large amounts of soil have to be handled with different machines, tools and working methods. Soils are more or less difficult to excavate depending on their properties.
