Multiscale Simulation of Non-Darcy Flows
(Chapter; Peer reviewed, 2012-06)In this work we present control volume multiscale methods which address problems on the interaction between pore scale and Darcy scale. For the case when linear equations govern the ow on the pore scale our solution converges ... -
Multivariate and conditional density estimation using local Gaussian approximations
(Doctoral thesis, 2016-09-23)Paper 1 ”Bias and bandwidth for local likelihood density estimation”: A local likelihood density estimator is shown to have asymptotic bias depending on the dimension of the local parameterization. Comparing with kernel ... -
Multivariate compound Poisson distributions and infinite divisibility
(Statistical report no. 33, Research report, 1999-03) -
Multivariate count autoregression
(Journal article; Peer reviewed, 2020)We are studying linear and log-linear models for multivariate count time series data with Poisson marginals. For studying the properties of such processes we develop a novel conceptual framework which is based on copulas. ... -
Mønstre og kvalitet. Analyse av samtaler i matematikkundervisning
(Master thesis, 2015-06-03)Oppgaven diskuterer hvordan man kan analysere samtaler mellom lærer og elever i matematikkundervisning. Deretter diskuterer oppgaven hva som kjennetegner en kvalitativ god samtale. -
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 ... -
Network analysis of Arabidopsis mitochondrial dynamics reveals a resolved tradeoff between physical distribution and social connectivity
(Journal article; Peer reviewed, 2021)Mitochondria in plant cells exist largely as individual organelles which move, colocalize, and interact, but the cellular priorities addressed by these dynamics remain incompletely understood. Here, we elucidate these ... -
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 ... -
Nonemptiness of severi varieties on enriques surfaces
(Journal article; Peer reviewed, 2023)Let (S,L) be a general polarised Enriques surface, with L not numerically 2-divisible. We prove the existence of regular components of all Severi varieties of irreducible nodal curves in the linear system |L| , that is, ... -
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 ...
