An acoustical study of trombone performance, with special attention to auditory feedback deprivation
(Master thesis, 2014)When discussing how instruments work and how performers play them, the matter can be viewed from the standpoint of the musician or the scientist. In an attempt to bridge the gap between what science and musical experience ... -
Antideuterons as Signature for Dark Matter
(Master thesis, 2011)In this thesis, we examine the antideuteron spectra from annihilations of dark matter in the form of Weakly Interacting Massive Particles (WIMPs). The so-called coalescence model is commonly used to describe the production ... -
Calculation of Terminal Currents in Single Photon Excited Avalanche Photodiodes.
(Master thesis, 2012)We use the Shockley-Ramo (SR) theorem to calculate terminal currents in single photon excited APDs. A unified notation for the SR theorem is introduced, and we derive the theorem in those particular ways found useful for ... -
Carbon Dioxide Intercalation in Sodium Fluorohectorite Clay
(Master thesis, 2011)Wide angle X-ray Scattering (WAXS) measurements of the layered synthetic silicatesodium fluorohectorite (NaFh) when exposed to pressurized carbon dioxideare reported. With a custom made sample holder placed on top of a ... -
CFD Study of a 10 MW Offshore Horizontal Axis Wind Turbine Blade
(Master thesis, 2011)This Master thesis is a study of wind turbine aerodynamics on a 10 MW offshore wind turbine blade with a Computational Fluid Dynamics, CFD, approach.The objectives for the thesis were, (i) make a Computer Aided Design, ... -
Dark Matter Contribution to the Isotropic Extragalactic Gamma-Ray Background
(Master thesis, 2011)This thesis looks into the possibilities of finding a signal from dark matter annihilation in the isotropic extragalactic gamma-ray background radiation (EGBR), and compares the the results with data from the Fermi Large ... -
Development of a spectrometer system to remotely sense mesospheric temperature.
(Master thesis, 2011)At nighttime the strongest source of radiation is the hydroxyl night glow. By measuringthe different lines within a band it is possible to calculate the temperature of the mesosphere more than 85km above ground. In order ... -
Dispersion hardening during annealing at low Temperatures in four 3xxx Al-Mn-Fe-Si Alloys
(Master thesis, 2012)3xxx aluminiumslegeringer har Mangan som hovedlegeringselement, og får sin styrke fra plastisk bearbeidelse. 3xxx legeringer har tidligere blitt ansett for å oppnå neglisjerbare endringer i hardhet og styrke som følge av ... -
Experimental Studies of Flow- and Electric Properties of Oil Droplets Including Suspended Clay Particles
(Master thesis, 2012)Experiments on oil droplets made of silicone oil and sodium-fluorohectorite (Na-Fh) clay particles suspended in castor oil were performed. The electric field (E-field)-induced structuring of clay particles placed inside ... -
Field Theory at finite Temperature and Density: Applications to Quark Stars
(Master thesis, 2012)Abstract:In this thesis we will consider different thermal field theories, and derive an equation of state for deconfined matter.This equation of state will be used in the Tolman-Oppenheimer-Volkoff (TOV)-equations to ... -
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 ... -
Måling og modellering av vanntransportegenskaper til svelleband til høyspenningskabler
(Master thesis, 2011)Vanntrevekst er en av de viktigste grunnene til elektrisk havari i høyspenningskabler.Vanntrær begynner å vokse når den relative fukten(RH) i kabelisolasjonenoverstiger 70 %RH. Det er derfor viktig å holde en lav fuktigheti ... -
Modeling of the Intermediate Band Tandem Solar Cell: Using the AM1.5 Spectra
(Master thesis, 2011)In this thesis the results from simulations of a tandem intermediate band solar cell are presented and discussed. Renewable energy sources have become increasingly important, because of global environmental concerns. To ... -
Pion Condensation in the Linear Sigma Model
(Master thesis, 2011)In this thesis we study the phase diagram of quantum chromodynamics in an effective low-energy theory at zero baryon chemical potential but finite temperature and isospin density. We investigate pion condensation at finite ... -
Satellite mapping of particle precipitation effects on the Antarctic middle atmosphere
(Master thesis, 2011)The aim of this thesis is to study the effects of particle precipitation on O3 and OH caused by a moderate geomagnetic storm in late July 2009. The basis is data retrieved over Antarctica from the Odin and Aura satellites ... -
Structural properties of Ge doped multicrystalline Silicon wafers and Solar cells
(Master thesis, 2012)The efficiency of multi crystalline silicon solar cells is around 17% but the theoretical limit is 33,7 %. Impurities and dislocations are the main sources for degradation of the solar cell efficiency, especially the ... -
Symmetry Breaking in ordinary and supersymmetric Models of Quantum Field Theory
(Master thesis, 2012)This thesis will consider two different theories, and apply variational techniquesto each, in order to investigate their true ground states and the possibility ofsymmetry breaking.A scalar field theory is modified by ... -
