Upscaled modeling of CO2 injection and migration with coupled thermal processes
(Peer reviewed; Journal article, 2013)A practical modeling approach for CO2 storage over relatively large length and time scales is the vertical-equilibrium model, which solves partially integrated conservation equations for flow in two lateral dimensions. We ... -
Upscaling of Nonisothermal Reactive Porous Media Flow under Dominant Péclet Number: The Effect of Changing Porosity
(Peer reviewed; Journal article, 2016)Motivated by rock-fluid interactions occurring in a geothermal reservoir, we present a two-dimensional pore scale model of a thin strip consisting of void space and grains, with fluid flow through the void space. Ions in ... -
Upscaling of the Coupling of Hydromechanical and Thermal Processes in a Quasi-static Poroelastic Medium
(Peer reviewed; Journal article, 2018-08)We undertake a formal derivation of a linear poro-thermo-elastic system within the framework of quasi-static deformation. This work is based upon the well-known derivation of the quasi-static poroelastic equations (also ... -
Upscaling, analysis, and iterative numerical solution schemes for thermo-poroelasticity
(Doctoral thesis, 2019-06-28)The main objectives of this research project is to provide part of the mathematical models and simulation technology required to assess large-scale deployment of thermomechanical subsurface energy storage in the context ... -

Using coding and non-coding rare variants to target candidate genes in patients with severe tinnitus
(Journal article; Peer reviewed, 2022)Tinnitus is the phantom percept of an internal non-verbal set of noises and tones. It is reported by 15% of the population and it is usually associated with hearing and/or brain disorders. The role of structural variants ... -
Using Mixed-Effects Models to Analyze Speech Comprehension and Psychological Variables in Patients With Chronic Tinnitus
(Master thesis, 2023-11-20) -
Using sensitivities and vertical-equilibrium models for parameter estimation of CO2 injection models with application to Sleipner data
(Peer reviewed; Journal article, 2017-07)A key part of planning CO2 storage sites is to devise a monitoring strategy with proper modelling support. Herein, we show how a simulation framework that incorporates adjoint-based sensitivities can be combined with ... -
Using the bottleneck distance to compare homological methods of detecting atmospheric rivers

Utfordringar P-elevar møter på matematikkeksamen. Førebuingar som kan nytte.
(Master thesis, 2019-06-22)I masterprosjektet har eg forsøkt å finne ut kva utfordringar P elevar møter på eksamen, og kva førebuingar ein kan gjere for å prestere godt på eksamen. Med P elevar meiner eg dei elevane som vel praktisk matematikk på ... -
Utfordringer i klasseromssamtalen
(Master thesis, 2022-06-01)Utfordringer i klasseromssamtalen er en masteroppgave som har tatt for seg temaet kommunikasjon og klasseromssamtaler i matematikkundervisning. Sammen med en medstudent har jeg gjennomført et opplegg i tre forskjellige ... -
Validating a Computational Framework for Ionic Electrodiffusion with Cortical Spreading Depression as a Case Study
(Journal article; Peer reviewed, 2022)Cortical spreading depression (CSD) is a wave of pronounced depolarization of brain tissue accompanied by substantial shifts in ionic concentrations and cellular swelling. Here, we validate a computational framework for ... -
Validation of close‐kin mark–recapture (CKMR) methods for estimating population abundance
(Peer reviewed; Journal article, 2019)1. Knowing how many individuals there are in a population is a fundamental problem in the management and conservation of freshwater and marine fish. We compare abundance estimates (census size, Nc) in seven brook trout ... -
Valuation of Guaranteed Investment Contracts

Value of different data types for estimation of permeability
(Master thesis, 2011-06-01)The interrelation between sensitivity, non-linearity and scale, associated with the inverse problem of identifying permeability from measurements of fluid flow, is considered. The gouverning equations for fluid flow in a ... -
Varied mechanisms and models for the varying mitochondrial bottleneck
(Peer reviewed; Journal article, 2019-11-20)Mitochondrial DNA (mtDNA) molecules exist in populations within cells, and may carry mutations. Different cells within an organism, and organisms within a family, may have different proportions of mutant mtDNA in these ... -
Vascular responses to radiotherapy and androgen-deprivation therapy in experimental prostate cancer
(Peer reviewed; Journal article, 2012-05-23)Background: Radiotherapy (RT) and androgen-deprivation therapy (ADT) are standard treatments for advanced prostate cancer (PC). Tumor vascularization is recognized as an important physiological feature likely to impact on ... -
