Modeling the propagation of streamers in liquids - The Townsend-Meek criterion and a novel model for photoionization
(Master thesis, 2015)Conducting channels forms when a dielectric liquid is subjected to high electric stress. These channels are know as streamers, and if allowed the time to form and propagate, they can lead to an electrical breakdown. Sintef ... -
Modelling of heat transfer and fluid flow in a silicon melt for the Czochralski process
(Master thesis, 2018)In order to get a better understanding of the heat transfer and the fluid flow of a silicon melt in the Czochralski process, the focus has been to use modelling together with theoretical analysis to gather more understanding ... -
Modelling Underwater Hyperspectral Images
(Master thesis, 2017)The underwater hyperspectral imager is a new type of imager able to acquire hyperspectral images under water. Common consumer cameras have poor spectral resolution and only captures light in three bands, in the red, green ... -
Monte Carlo Simulations of a simple Model for Charge Storage in a Single-file Nanopore
(Master thesis, 2015)This Master's thesis is focused upon charge storage in a nanopore of a capacitor. It introduces a simple model, where the only present interactions are electrostatic and steric effects, which allows only one ion to be at ... -
Monte Carlo Simulations of Diffusion MRI in Restricted Geometries
(Master thesis, 2017)The main part of the thesis has been to implement an environment in Matlab, suitable for simulating diffusion MRI. The implementation consists of a simulation of self-diffusion, wall detection and interaction for the ... -
NAO-Influence on Temperature Trends in Norway and Canada for the last 50 Years
(Master thesis, 2015)The paper looks at how much of the temperature changes the last 50 years in Norway and East Canada/West Greenland that can be explained by NAO, and how much that must be explained by other weather drivers. Finally it also ... -
Novel Short-pulsed Holmium-fiber Master Oscillator Power Amplifier for LiDAR applications

Nuclear Equation of State and Neutron Stars
(Master thesis, 2017)In this thesis, we study the mass-radius relation of neutron stars. This relation is computed using stellar structure equations and an equation of state. We use the Tolman-Oppenheimer-Volkoff (TOV) equation and the mass ... -
Numerical Investigations on Nanobubble Stability
(Master thesis, 2015)This thesis discusses the stability and lifetime of bulk and surface nanobubbles. Two numerical models are presented which have been developed in order to investigate aspects of the dynamic equilibrium mechanism using ... -
On the Stability of the Local Load Sharing Fiber Bundle Model
(Master thesis, 2016)This thesis investigates a generalized history-independent local load sharing (LLS) fiber bundle model for two dimensional interfacial fractures. When the failure threshold of the fibers are assigned according to the ... -
Parallell partikkeltransport implementert i Python med MPI
(Master thesis, 2017)Det er skrevet et program i Python for å beregne parallell partikkeltransport. Som numerisk integrator ble fjerdeordens Runge-Kutta-metode brukt for å beregne partikkeltransporten i et hastighetsfelt gitt ved et analytisk ... -
Partial Discharges on an Epoxy Surface due to Water Droplets
(Master thesis, 2011)Offshore wind turbines are exposed to a very harsh environment and can sustain significant damage during operation. In this thesis work, the possibilities of partial discharges in an insulation system of an offshore wind ... -
Påvirkningen av temperaturgradienter for tolkningen av rotasjonstemperaturer
(Master thesis, 2018)Hydroksyl (OH) utstråling er en fotokjemisk reaksjon som skjer i et relativt tynt område ($\sim$5 km) sentrert rundt ca 90 km høyde. I denne oppgaven ble det laget et syntetisk spektrum ved hjelp av en steady-state kjemimodell ... -
Photoluminescence of InAs/Ga(N)As quantum dot intermediate band solar cells
(Master thesis, 2014)In this thesis InAs/Ga(N)As quantum dot intermediate band solar cells (QDIBSCs) are studied using photoluminescence (PL) spectroscopy. The samples in this thesis have been complete QD-IBSCs with doping in the substrate, the ... -
Polarimetry using classical polarizing components and nanostructured beam splitting surfaces
(Master thesis, 2018)Two methods for generation and analysis of the polarization state of light are studied in this thesis. The first method is based on a traditional bulk design consisting of two active components and 3 passive components in ... -
Polarization beam-splitting metasurfaces analyzed using the finite-difference time-domain software EMTL
(Master thesis, 2018)Using the FDTD solver EMTL, as well as a new way of thinking about metasurfaces, the primary innovation of this thesis was to take two individual birefringent patterns and interleave them in a checkered pattern. This ... -
