1. Boundary integral methods for Stokes flow : Quadrature techniques and fast Ewald methods
Sammanfattning : Fluid phenomena dominated by viscous effects can, in many cases, be modeled by the Stokes equations. The boundary integral form of the Stokes equations reduces the number of degrees of freedom in a numerical discretization by reformulating the three-dimensional problem to two-dimensional integral equations to be discretized over the boundaries of the domain.

2. Algorithms for Molecular Dynamics Simulations
Sammanfattning : Methods for performing large-scale parallel Molecular Dynamics(MD) simulations are investigated. A perspective on the field of parallel MD simulations is given. Hardware and software aspects are characterized and the interplay between the two is briefly discussed. LÄS MER
3. Moment Method Analysis of Antennas in Reverberation Chambers and Cylindrical Structures
Sammanfattning : This thesis is a collection of papers using the method of moments for numerical analysis. The papers can be divided into two main groups; a study of antennas in reverberationchambers, and a study of antennas in cylindrical structures.The reverberation chamber is a metal cavity for measuring antennas and other devices.

5. Interfacial behaviours of ionic fluids : Theory and simulations
Sammanfattning : This thesis and the papers included is an \textit{in silico} study of how charged particles interact and behave close to surfaces, and how to treat these interactions in simulations. This type of systems is found in widely different contexts, from capacitors to biological cells. LÄS MER
