A Framework for Constructing and Evaluating Probabilistic Forecasts of Electricity Prices: A Case Study of the Nord Pool Market
(Master thesis, 2011)A framework for a 10-day ahead probabilistic forecast based on a deterministic model is proposed. The framework is demonstrated on the system price of the Nord Pool electricity market. The framework consists of a two-component ... -
Effects of substrate annealing on the gold-catalyzed growth of ZnO nanostructures
(Journal article; Peer reviewed, 2011)The effects of thermal substrate pretreatment on the growth of Au-catalyzed ZnO nanostructures by pulsed laser deposition are investigated. C-plane sapphire substrates are annealed prior to deposition of a thin Au layer. ... -
Numerical Simulations of Flow Past a Truss Tower with an Evaluation of Tower Shadow Models for Wind Turbines
(Master thesis, 2011)The performance of steady-state tower shadow models for a wind turbine truss tower have been evaluated. The Reynolds-Averaged-Navier-Stokes (RANS) approach, in conjunction with the $k-omega$ Shear-Stress-Transport (SST) ... -
Analysis of dominance hierarchies using generalized mixed models
(Master thesis, 2011)This master s thesis investigates how well a generalized mixed model fits different dominance data sets. The data sets mainly represent disputes between individuals in a closed group, and the model to be used is an adjusted, ... -
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 ... -
Hyperbolic Conservation Laws with Relaxation Terms: A Theoretical and Numerical Study
(Master thesis, 2011)Hyperbolic relaxation systems is an active field of research, with a largenumber of applications in physical modeling. Examples include modelsfor traffic flow, kinetic theory and fluid mechanics. This master s thesis is ... -
Fracturing of Optimal Paths in a Random Lattice
(Master thesis, 2011)The subject of this thesis is the study of the creation of fault lines in a random lattice, provoked by the successive failure of optimal paths. Using the recently developed Optimal Path Cracked model, we investigate how ... -
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 ... -
Superdense dark matter clumps
(Journal article; Peer reviewed, 2011)We describe the cosmological scenario for the formation of superdense dark matter clumps. As an interesting particular example the case of superheavy neutralino as DMparticles is considered. The small-scale superdense ... -
A Density Functional Theory Study of Hydrogen Transfer and Rotational Barriers in Vitamin E-like Molecules
(Master thesis, 2011)A study of the antioxidant property of two vitamin E simplifications with density functional theory has been done. In one of the simplifications the phytyl tail and the methyl group on the heterocyclic ring in vitamin E ... -
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 ... -
Reconstruction of Images From a Compact Spectral Camera
(Master thesis, 2011)Hyperspectral imaging provides a lot of information about the imaged scene, and has several applications. The purpose of this work is to reconstruct hyperspectral images from pictures captured with a compact hyperspectral ... -
Trykkutvikling under CO2-lagring: Numerisk simulering på Sleipnerinspirert modell

Minimum Ignition Energy in a Hygrogen Combustible Mixture
(Master thesis, 2011)In this thesis the Minimum Ignition Energy, in a hydrogen-air system, is studied by Direct Numerical Simulations (DNS) in a program called the Pencil Code. The heat source used to achieve ignition is modeled by a Gaussian ... -
Spin-sensitive long-range proximity effect in ferromagnet/spin-triplet-superconductor bilayers
(Journal article; Peer reviewed, 2011)The discovery of noncentrosymmetric superconductors, such as CePt3Si, and chiral superconductors, such as Sr2RuO4, calls for experimental methods to identify the presence of spin-triplet pairing. We here demonstrate a ... -
Spin Current in Generic Hybrid Structures due to Interfacial Spin-Orbit Scattering
(Journal article; Peer reviewed, 2011)We demonstrate a general principle that hybrid structures of any sort inevitably will give rise to a pure spin current flowing parallel to the interface region when a charge current is injected. This stems from the broken ... -
Survival Analysis using Integrated Nested Laplace Approximations: A Case Study of House Sparrows from Aldra
(Master thesis, 2011)The animal model is a generalized linear mixed model (GLMM) often used in evolutionary biology and animal breeding. Integrated Nested Laplace Approximation (INLA) is a quite new methodology for making fast non-sampling ... -
