A random Matrix Approach to collective Trends of falling and rising Stock Markets
(Master thesis, 2011)An inverse statistics analysis of one minute stock quotes from 492 large Europeancompanies has revealed the existence of a gain-loss asymmetry in thefollowing index. The gain-loss asymmetry differs from that observed for ... -
Analysis of Intermediate Band Solar Cell Performance
(Master thesis, 2011)This is the Master s Thesis of Eirik Timo Bøe Vilpponen, and was writtenat the Department of Physics at the Norwegian University of Science andTechnology (NTNU). The thesis is twofold, the first part being the comple-tion ... -
Asymmetriske Energivariasjoner i Turbulens: Invers statistikk metode for beskrivelse av asymmetrisk energivariasjon
(Master thesis, 2011)Energivariasjon i fullt utviklet turbulens er studert. I en tidsserie for tur- bulens energi er det oppdaget en asymmetri mellom positive og negative energiendringer. Invers statistikk metode gir en mulighet til å studere ... -
Atomistic Implications of Stacking Fault Energy on Dislocation - Void Interactions
(Master thesis, 2012)Irradiation hardening due to voids can be a significant result of radiation damage in metals, but treatment of this by elasticity theory of dislocations is difficult when the mechanisms controlling the obstacle strength ... -
Characterization of electrical activity and lifetime in compensated multicrystalline silicon
(Master thesis, 2011)This master's thesis concerns the electrical activity and lifetime in compensated multicrystalline silicon wafers used for solar cell production.Resistivity profiles across grain boundaries have been obtained by a Four ... -
Characterization of GaN:ZnO p-n junctions
(Master thesis, 2011)In this master thesis, thin lms of ZnO doped with various cobalt concentra-tions have been grown using Pulsed Laser Deposition (PLD). This growthtechnique is preferred because it is able to grow thin lms from a targetmaterial ... -
Clay-Oil Droplet Suspensions in Electric Field
(Master thesis, 2012)Silicone oil droplets containing synthetic smectite clay submerged in another immiscible organic oil have been studied by observing clay particle movement, oil circulation and drop deformation when an electric field is ... -
Clustering during Natural Aging and its Effect on Precipitation Hardening in Al-Mg-Si Alloys
(Master thesis, 2011)The effect of clustering during natural aging of three different Al-Mg-Sialloys with equal Mg/Si-ratios, but different Mg+Si contents have beenstudied through hardness measurements and transmission electron mi-croscopy ... -
Coherent Plane-Wave Compounding in Medical Ultrasound Imaging: Quality Investigation of 2D B-mode Images of Stationary and Moving Objects.
(Master thesis, 2012)Coherent plane-wave compounding is the coherent summation of several successive plane waves incident at different angles. This thesis presents results from simulations and in vitro and in vivo measurements of stationary ... -
Complex Networks: Development of a three particle reaction-diffusion model on a complex network.
(Master thesis, 2011)This master thesis couples endemic modeling of diseases with complex networks and diffusion. Previous established models are visited and results for these are reproduced. The goal of this thesis was to expand upon these ... -
Development and testing of a Linnik Interference Microscope for Sub-surface Inspection of Silicon during moving Indentation
(Master thesis, 2012)Fixed-abrasive diamond wire sawing is a promising technique for reduction of costs related to sawing of silicon wafers for solar cells. The microscopic mechanisms of material removal in the process are however not fully ... -
Development of 3-D Quantitative Analysis of Multi-Photon Microscopy Images
(Master thesis, 2012)Motivation: Cartilage is a robust but flexible connective tissue found in most joints of the body. The collagen fibres present in the extracellular matrix of cartilage contribute to its tensile strength and stiffness. The ... -
Diffusjon av vann i sotfylte kappematerialer for polymere sjøkabler
(Master thesis, 2011)Vanntrevekst er den viktigste årsaken til aldring i polymerisk isolasjon i mellomspenningskabler. Sia vanntrær ikke dannes ved lav relativ fuktighet (R.H.), er det viktig å holde relativ fuktighet i isolasjonen lav så lenge ... -
Electrodeposition of Metal Oxides for Solar Cell Applications
(Master thesis, 2012)This thesis investigates the electrodeposition process of zinc-, copper-, silver-, and silver copperoxides at cathodic and anodic voltages. Silver copper oxide has been successfully electrodepositedon a substrate of PtSi ... -
Electromagnetic Scattering: A Surface Integral Equation Formulation
(Master thesis, 2012)A numerical approach to solving the problem of electromagnetic (EM) scattering on a single scatterer is studied. The problem involves calculating the total EM field in arbitrary observation points when a planar EM wave is ... -
Engineered Surfaces for Redirection of Light
(Master thesis, 2011)It is of interest to construct windows that can spread the transmitted light in a specified manner. The Kirchhoff approximation in the geometrical optical limit in combination with a chosen general form of the window ... -
