1. Efficient Calculations of Two-Dimensional Radar Cross-Section Using DGFEM
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : A two-dimensional discontinuous Galerkin finite element method algorithm in the time domain was developed for calculation of the radar cross-section of an arbitrary object. The algorithm was formed using local nodal basis functions in each element and coupling them via numerical upwind flux. LÄS MER
2. Cyclotron Damping in Magnetized Plasmas
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : The aim of this thesis was to study the cyclotron damping in magnetized plasmas using a different approach to the dielectric tensor that is the stardard way to study this case. In this approach given we deduce a set of coupled differential equations that give us the evolution of the electric field and the distribution function. LÄS MER
3. Effektiva lösningsmetoder för Schrödingerekvationen : En jämförelse
Kandidat-uppsats, Tillämpad beräkningsvetenskapSammanfattning : In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). LÄS MER
