Analysis and Approximation of Coupled 1D-3D Flow Models
(Doctoral thesis, 2020-03-18)In this thesis, we consider a specific instance of mixed-dimensional partial differential equations (PDEs) commonly referred to as the coupled 1D-3D flow model. The model itself consists of the Poisson equation defined on ... -
Analysis and Development of Phenomenological Models for the Relative Biological Effectiveness in Proton Therapy
(Doctoral thesis, 2019-08-23)Proton therapy is undergoing a rapid development making it increasingly popular as a treatment of cancer. Protons interact differently with the tissue compared to conventional radiation therapy with photons, resulting in ... -
Analysis and Numerics of strongly degenerate Convection-diffusion Problems Modelling sedimentation-consolidation Processes
(Department of Applied Mathematics report, Research report, 1999-09) -
Analysis and Simulation of Polymer Injectivity Test in a High Temperature High Salinity Carbonate Reservoir
(Journal article; Peer reviewed, 2021-05-27)Polymer flooding has gained much interest within the oil industry in the past few decades as one of the most successful chemical enhanced oil recovery (CEOR) methods. The injectivity of polymer solutions in porous media ... -
Analysis of 3 years of precipitation measurements from the Micro Rain Radar located at the Geophysical Institute
(Master thesis, 2013-11-20)An analysis of three years of vertically pointing Micro Rain Radar (MRR) data from the measurement platform at the Geophysical Institute has been performed. The measurement period started at 13.04.2010 and ended at 12.04.2013. ... -
Analysis of 3D Pixel Detectors for the ATLAS Inner Tracker Upgrade
(Master thesis, 2017-06-16)The silicon 3D pixel detector represent a detector technology that has a higher radiation tolerance compared to the conventional planar pixel detectors. This detector technology is one of the technologies proposed to be ... -
Analysis of a Costly Fiberglass-Polyester Air Filter Fire
(Journal article; Peer reviewed, 2022)In September 2020, a fire at a liquefied natural gas (LNG) plant in the Arctic areas of Norway received national attention. In an unengaged air intake, the heat exchanger designed to prevent ice damage during production ... -
Analysis of a low-level coastal jet off the western coast of Norway
(Peer reviewed; Journal article, 2014)Offshore wind installations depend strongly on an improved knowledge of the atmospheric and ocean conditions affecting the marine atmospheric boundary layer (MABL). In particular the better understanding of atmospheric ... -
Analysis of AMR and Other Mesh-Refinement Techniques for Inviscid Fluid Problems
(Master thesis, 2021-06-01) -
Analysis of Blue Corona Discharges at the Top of Tropical Thunderstorm Clouds in Different Phases of Convection
(Journal article; Peer reviewed, 2022)We report on observations of corona discharges at the uppermost region of clouds characterized by emissions in a blue band of nitrogen molecules at 337 nm, with little activity in the red band of lightning leaders at 777.4 ... -
An Analysis of CO2, CH4 and Mixed CO2-CH4 Gas Hydrates: Experimental Phase Equilibria Measurements and Simulations with State-of-the-Art Software
(Master thesis, 2014-06-14)The enormous amount of CH4 trapped in gas hydrates has led to a growing focus on gas hydrates as a potential future energy source. One of the proposed methods for the production of CH4 from these deposits, is to exchange ... -
Analysis of coastal cod (Gadus morhua L.) sampled on spawning sites reveals a genetic gradient throughout Norway's coastline
(Peer reviewed; Journal article, 2018-07-09)Background. Atlantic cod (Gadus morhua L.) has formed the basis of many economically significant fisheries in the North Atlantic, and is one of the best studied marine fishes, but a legacy of overexploitation has depleted ... -
Analysis of Control Volume Heterogeneous Multiscale Methods for Single Phase Flow in Porous Media
(Peer reviewed; Journal article, 2014)The standard approximation for the flow-pressure relationship in porous media is Darcy's law that was originally derived for infiltration of water in fine homogeneous sands. Ever since there have been numerous attempts to ... -
Analysis of CryoSat’s radar altimeter waveforms over different Arctic sea ice regimes
(Journal article, 2014-06-11)Satellite altimetry has been used to derive information about sea ice thickness in the Arctic already for several decades. As part of the algorithms applied the shape of the radar signal is used to identify leads, the open ... -

Analysis of Fatty Acids by High Performance Liquid Chromatography and Electrospray Ionization-Mass Spectrometry
(Master thesis, 2019-09-28)Fatty acids (FA) have been traditionally analyzed by gas chromatography (GC) as fatty acids methyl esters (FAME) and more recently using mass spectrometry (MS) detection. Since high performance liquid chromatography (HPLC) ... -
Analysis of IgM sub-variants related to ancestral tetraploidy in salmonid fish
(Doctoral thesis, 2013-03-21)Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) possess two paralogous IgM heavy chain (μ) genes related to ancestral tetraploidy. Accordingly, IgM subpopulations of Atlantic salmon and brown trout can be ... -
Analysis of immunoglobulin and T cell receptor gene expression in ballan wrasse (Labrus bergylta) revealed an extraordinarily high IgM expression in the gut
(Peer reviewed; Journal article, 2019)The serum IgM concentration of ballan wrasse is relatively high, estimated to approximately 13 mg/ml in adult wild fish of 800 g. The present study revealed an unusual high abundance of IgM mRNA in the gut of ballan wrasse. ... -
Analysis of left truncated data with an application to insurance data
