Renormalised Intrinsic and Extrinsic Impurity Induced Spin-orbit Scattering in Graphene
(Master thesis, 2012)We study the effect of an impurity potential on spin-memory loss in graphene. Various general methods for finding the spin-orbit related effect of a slowly varying impurity potential on a semiconductor have been examined. ... -
Scalar wave scattering from two-dimensional, randomly rough surfaces
(Master thesis, 2011)We study scalar waves scattered from self-affine and Gaussian correlated surfaces. The simulations are performed using rigorous simulation of the integral equations derived from the Helmholtz equation, describing a scalar ... -
Silicon Quantum Dots in a Silicon Dioxide Matrix
(Master thesis, 2011)The aim of the master work was to both produce silicon quantum dots in a SiO2 matrix, and to optically characterize them. The main goal of the optical characterization was to find the band gap of the produced quantum dots, ... -
Simulations of impact using the modified Gurson model
(Master thesis, 2012)We have performed modified Gurson model calibrations to the steel alloys Weldox 460E, Weldox 700E and Weldox 900E through finite element method (FEM) simulations of various tensile material tests performed, and used these ... -
Spectroscopic Mueller Matrix Analysis of Plasmonic Nanostructures Fabricated by Focused Ion Beam
(Master thesis, 2014)As nanofabrication has become more advanced over the last few decades, nanomaterials have received increased interest. One particular aspect of nanosized structures made of noble materials such as gold, is the peculiar ... -
Spin-Polarized Non-Local Transport in Hybrid Structures with Magnetic and Superconducting Correlations
(Master thesis, 2012)In this thesis we theoretically examine spin-polarized non-local transport in two junctions built up by materials with superconducting and magnetic properties. The first consists of a Zeeman-split superconductor placed ... -
Structure of Clean and Oxidized PdCu(100) Surfaces at the Atomic Scale
(Master thesis, 2012)In this thesis, clean and oxidized Pd(57)Cu(43)(100) single crystal surfaces were studied by LEED, STM and XPS in UHV conditions. The clean sample annealed to 300 degrees C has been found to either consist of ordered domains ... -
System Identification of Unmanned Aerial Vehicles
(Master thesis, 2012)The least squares method has been applied to estimate parameters inan aerodynamic model of a simulated aircraft, using data that can beexpected to available from sensors on an Unmanned Aerial Vehicle. Acombination of two ... -
The Effect of Thermophoresis on the Particle Deposition on a Cylinder
(Master thesis, 2012)The effect of thermophoresis on the particle deposition on a cooled cylinderin non-isothermal laminar gas ow has been studied using Direct NumericalSimulations (DNS). Simulations where thermophoresis have been taken ... -
The Local Level-Set Extraction Method for Robust Calculation of Geometric Quantities in the Level-Set Method
(Master thesis, 2012)The level-set method is an implicit interface capturing method that can be used in two or more dimensions. The method is popular e.g. in computer graphics, and as here, in simulations of two-phase flow. The motivation for ... -
The Relative Influence of Solar Radiative and Solar Geomagnetic Variation on the Dynamics of the Polar Upper Mesosphere
(Master thesis, 2012)Resent research indicates that there might be a connection between perturbation of the Earth's geomagnetic field caused by solar wind, and the atmospheric circulation. In this project the mesospheric meridional and zonal ... -
Time Series Analysis of Electricity Prices: A comparative study of power markets
(Master thesis, 2011)During the past few decades, the power sectors of several countries have been substantially reorganized, and liberalized markets for trading of electricity have been established. In this report, evidence from six electricity ... -
Trykkutvikling under CO2-lagring: Numerisk simulering på Sleipnerinspirert modell
(Master thesis, 2011)For sammendrag, se oppgavebesvarelsen. -
Two-dimensional Simulations of Particle Deposition on a Cylinder in a Turbulent Cross Flow at Intermediate Reynolds Numbers
(Master thesis, 2011)The behaviour of particles in turbulent flow, with emphasis on particle deposition on both the frontside and backside of a cylinder, was investigated by means of Direct Numerical Simulations. One-way coupling between the ... -
X-ray Studies of Capture, Storage and Release of CO2
(Master thesis, 2012)We show experimentally that CO2 intercalates into the interlayer spaceof the synthetic smectite clay Li-fluorohectorite (LiFh). The intercalationoccurs for a range of conditions in terms of pressure (5 bar to 20 bar) ...
