Ferromagnetic Resonance Spectroscopy Studies of Permalloy/Copper/Chromium/Copper thin films
(Master thesis, 2014)A theroretical and experimental study of 10Py/10Cu, 10Py/10Cu/xCr/10Cu (with x=4,7, 10,13 nm) thin films has been performed. The thin films were fabricated by the sputter deposition technique at NTNU Nanolab and afterwards ... -
A CUDA Back-End for the Equelle Compiler.
(Master thesis, 2014)As parallel and heterogeneous computing becomes more and more a necessity for implementing high performance simulators, it becomes increasingly harder for scientists and engineers without experience in high performance ... -
Optical Properties and Composition of Fe:ZnS Films
(Master thesis, 2014)Iron doped ZnS thin films were deposited using the physical vapor deposition technique over a concentration range of 0-12% Fe. The thickness and composition of the films were measured with a profilometer and EDS, respectively, ... -
A Study of Rotational Water Waves using Bifurcation Theory
(Master thesis, 2014)This thesis is concerned with the water wave problem. Using local bifurcation we establish small-amplitude steady and periodic solutions of the Euler equations with vorticity. Our approach is based on that of Ehrnström, ... -
Intermediate Band Solar Cells Based on Cr:ZnS: Device Characterization and Simulation
(Master thesis, 2014)Intermediate band solar cells (IBSCs) are emerging, potentially high efficiency, solar cells. In this work, IBSCs based on zinc-sulfide with a high chromium doping density (Cr:ZnS), are fabricated, characterized and gradually ... -
"Never at Rest" - Anvendelse av kraftbegrepet i lærebøker i fysikk for videregående skole
(Master thesis, 2014)Denne oppgaven har undersøkt hvordan kraft behandles i lærebøker i fysikk beregnet på elever i den videregående skolen i Norge. Læreverkene <> og <> for Fysikk 1 og Fysikk 2, i alt fire bøker, har dannet grunnlaget for ... -
Number Theoretic Properties of Elliptic Curves
(Master thesis, 2014)In this thesis we will look at some of the theory of elliptic curves. We will use this for some number theoretical examples, use methods to determine the number of points on an elliptic curve over finite fields, and also ... -
Extracting room geometry from impulse response measurements
(Master thesis, 2014)An algorithm for establishing room parameters from measured impulse responses is created and implemented in matlab. The script is defined for synthetic and measured impulse responses. The setup is optional placement of a ... -
3D modelling of β'' in Al-Mg-Si: towards an atomistic level ab initio based examination of a full precipitate enclosed in a host lattice
(Journal article, 2014)We extend a first principles based hierarchical multi-scale model scheme for describing a fully coherent precipitate in a host lattice to 3D simulations. As our test system, the needle-shaped main hardening Al–Mg–Si alloy ... -
Investigation of Co2AlO4/CeO2 Catalyst for N2O Abatement using Electron Microscopy Techniques
(Master thesis, 2014)A N2O abatement catalyst of a Co2AlO4 active phase and CeO2 support phase has been investigated using transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM) and scanning electron microscopy ... -
Water waves with compactly supported vorticity: A functional-analytic approach to bifurcation theory and the mathematical theory of traveling water waves
(Master thesis, 2014)We study the mathematical theory of water waves. Local bifurcation theory is also discussed, including the Crandall-Rabinowitz theorem; an abstract theorem used to establish the presence of bifurcation points in the zero ... -
Simulation of nonlinear wave propagation in ultrasound.
(Master thesis, 2014)Nonlinear wave propagation has, for the last couple of decades, become an increasingly more important tool in medical ultrasound imaging. Creating ultrasound images from echoes in the second harmonic frequency band provides ... -
Statistical Modelling and Inference for Long Gene Expression Time Series
(Master thesis, 2014)The main objective of this thesis is to model and analyse long gene expression time series from a microarray study using the linear mixed effects model. This regression model is widely used in the fields of biology, ecology ... -
Sequence- and Analysis Optimization for Partial Volume Correction in Arterial Spin Labelling based Perfusion MRI.
(Master thesis, 2014)Arterial spin labelling (ASL) is a magnetic resonance imaging (MRI) based method that can measure quantitatively cerebral blood flow (CBF) by magnetically labelling the arterial blood that perfuse the brain tissue. The ... -
K-nearest neighbour methods for value of information in petroleum decision making
(Master thesis, 2014)In this thesis a parametric and non-parametric model are proposed for the study of value of information regarding decision making in petroleum industry. More specifically, a Gaussian method is introduced and analysed for ... -
Improvements of a numerical Algorithm for a certain Class of Colouring Problems
(Master thesis, 2014)We re-derive an algorithm used to calculate solutions for the edge-colouring and dimer problems for planar graphs. The theoretical background for this includes Pfaffian and then as Grassmann Integrals. We develop a new ... -
