Natural Convection in Layered Porous Media between Coaxial Cylinders
(Master thesis, 2015-05-31)In this thesis a mathematical model is developed to describe the onset of natural convection in a two-layer porous medium located between two coaxial cylinders, motivated by natural convection processes in geothermal ... -
Negativ binomisk regresjon med modifiserte sannsynligheter for nullobservasjoner; ZINB og ZANB
(Master thesis, 2013-11-06)Regresjonsmodeller av Poisson- og negativ binomisk fordeling blir ofte brukt til å utføre regresjonsanalyse på datasett innen medisin, biologi, økonomi og mange andre fagfelt. Det oppstår ofte tilfeller der andelen av ... -
New Conceptual Toxicokinetic Model to Assess Synergistic Mixture Effects between the Aromatic Hydrocarbon β-Naphthoflavone and the Azole Nocodazole on the CYP1A Biomarker in a Fish Cell Line
(Journal article; Peer reviewed, 2020)Toxicokinetic interactions with catabolic cytochrome P450 (CYP) enzymes can inhibit chemical elimination pathways and cause synergistic mixture effects. We have created a mathematical bottom-up model for a synergistic ... -
New examples of curves with a one-dimensional family of pencils of minimal degree
(Peer reviewed; Journal article, 2011-07-14)We give a geometric construction of sub-linear systems on a K3 surface consisting of smooth curves C with infinitely many g1 gon(C)’s. -
A new framework for assessing subject-specific whole brain circulation and perfusion using MRI-based measurements and a multi-scale continuous flow model
(Peer reviewed; Journal article, 2019-06-25)A large variety of severe medical conditions involve alterations in microvascular circulation. Hence, measurements or simulation of circulation and perfusion has considerable clinical value and can be used for diagnostics, ... -
A New Preconditioner for Iterative Phase Splitting Routines
(Master thesis, 2002)This thesis proposes a new, faster, non-iterative phase split estimate for multi component mixtures, and compares it with the previously published method of Wang and Stenby, in terms of their suitability as possible ... -
Nivådeling i matematikk på ungdomsskolen - en kvalitativ undersøkelse
(Master thesis, 2012-05-30)I Kunnskapløftet, K06, legges det stor vekt på tilpasset opplæring til hver enkelt elev. Flere ungdomsskoler har innført nivådeling i matematikk som et tiltak for å imøtekomme dette kravet. I Norge står enhetsskoletanken ... -

Non-commutative Harmonic Analysis: Generalization of Phase Correlation to the Euclidean Motion Group
(Master thesis, 2010-06-10)This thesis is about noncommutative harmonic analysis, and generalization of phase correlation to the euclidean motion group and application in image processing. -
Non-Slit Solutions to the Loewner Equation
(Master thesis, 2010-04-30)We study conditions on the driving term of the Loewner equation which guarantee that the equation generates slits. We construct a new family of examples of non-slit solutions which generalize Kufarev's example, in which ... -
Non-standard shocks in the Buckley-Leverett equation
(Peer reviewed; Journal article, 2015-08)It is shown how delta shock waves which consist of Dirac delta distributions and classical shocks can be used to construct non-monotone solutions of the Buckley–Leverett equation. These solutions are interpreted using a ... -
Nonholonomic geometry on finite and infinite dimensional Lie groups and rolling manifolds
(Doctoral thesis, 2012-03-30)Part I: We start by giving some background on the topics discussed in this thesis. The main topic of the thesis is nonholonomic geometry. In Chapter 1 we give an introduction of nonholonomic geometry in the context of ... -
Nonhydrostatic pressure in ocean models with focus on wind driven internal waves
(Doctoral thesis, 2010-02-05) -
Nonlinear cross-spectrum analysis via the local Gaussian correlation
(Journal article, 2017)Spectrum analysis can detect frequency related structures in a time series \(\{Y_t\}_{t\in\mathbb{Z}}\), but may in general be an inadequate tool if asymmetries or other nonlinear phenomena are present. This limitation is ... -
Nonlinear Effects During Transient Fluid Flow in Reservoirs as Encountered in Well-Test Analysis

Nonlinear spectral analysis via the local Gaussian correlation
(Journal article, 2017)The spectral distribution \(f(\omega)\) of a stationary time series \(\{Y_t\}_{t\in\mathbb{Z}}\) can be used to investigate whether or not periodic structures are present in \(\{Y_t\}_{t\in\mathbb{Z}}\), but \(f(\omega)\) ... -
Nonlinear Spectral Analysis: A Local Gaussian Approach
(Journal article; Peer reviewed, 2020)The spectral distribution f(ω) of a stationary time series {Yt}t∈Z can be used to investigate whether or not periodic structures are present in {Yt}t∈Z, but f(ω) has some limitations due to its dependence on the autocovariances ...
