A minimalist model for coevolving supply and drainage networks
(Journal article; Peer reviewed, 2021)Numerous complex systems, both natural and artificial, are characterized by the presence of intertwined supply and/or drainage networks. Here, we present a minimalist model of such coevolving networks in a spatially ... -
Misoppfatningar i algebra hjå elevar på første trinn i vidaregåande skule
(Master thesis, 2016-06-02)Denne oppgåva handlar om misoppfatningar i algebra hjå 1.års-elevar i vidaregåande skule. Målet med oppgåva har vore å gje meg som matematikklærar større innsikt i misoppfatningar og vanskar elevar møter i algebra. Eg har ... -
Misoppfatningar i algebra på ungdomsskulen - ei diagnostisk tilnærming
(Master thesis, 2012-05-24)Denne oppgåva handlar om elevar i 10.klasse sitt arbeid med algebra. Meir spesifikt har eg tatt utgangspunkt i ei kvalitativ tilnærming for å undersøka misoppfatningane dei har innan emnet. Vidare har eg sett på korleis ... -
Misoppfatninger innen betinget sannsynlighet for elever i den videregående skole
(Master thesis, 2016-09-20)Masteroppgaven handler om ulike misoppfatninger elever på videregående skole har innen emnet betinget sannsynlighet. I teorien belyses misoppfatninger, feilslutninger og heuristikker med hovedvekt på betinget sannsynlighet. ... -
Mitochondrial network state scales mtDNA genetic dynamics
(Peer reviewed; Journal article, 2019)Mitochondrial DNA (mtDNA) mutations cause severe congenital diseases but may also be associated with healthy aging. mtDNA is stochastically replicated and degraded, and exists within organelles which undergo dynamic fusion ... -
Mitochondrial network structure controls cell-to-cell mtDNA variability generated by cell divisions
(Journal article; Peer reviewed, 2023)Mitochondria are highly dynamic organelles, containing vital populations of mitochondrial DNA (mtDNA) distributed throughout the cell. Mitochondria form diverse physical structures in different cells, from cell-wide ... -
Mixed approach for coupled flow and mechanics in a fractured medium
(Master thesis, 2023-06-01)Denne avhandlingen presenterer en blandet endelig element metode for Biot ligningene for poroelastisitet i et reservoar, sammenkoblet med en blandet formulering av strømning innenfor en sprekk. Sprekken er representert som ... -
A Mixed Approach to the Poisson Problem with Line Sources
(Journal article; Peer reviewed, 2021)In this work we consider the dual-mixed variational formulation of the Poisson equation with a line source. The analysis and approximation of this problem is nonstandard, as the line source causes the solutions to be ... -
Mixed-dimensional auxiliary space preconditioners
(Journal article; Peer reviewed, 2020)This work introduces nodal auxiliary space preconditioners for discretizations of mixed-dimensional partial differential equations. We first consider the continuous setting and generalize the regular decomposition to this ... -
Mixed-dimensional poromechanical models of fractured porous media
(Journal article; Peer reviewed, 2022)We combine classical continuum mechanics with the recently developed calculus for mixed-dimensional problems to obtain governing equations for flow in, and deformation of, fractured materials. We present models in both the ... -
Model Construction with Support Vector Machines and Gaussian Processes through Kernel Search

Model development for efficient simulation of CO2 storage
(Doctoral thesis, 2018-02-16)Carbon capture and storage (CCS) is an important component of several initiatives to reduce global greenhouse gas emissions by injecting and storing CO2 in underground reservoirs. Simulation technology plays an important ... -
Model selection and parameter estimation for root architecture models using likelihood-free inference
(Peer reviewed; Journal article, 2019)Plant root systems play vital roles in the biosphere, environment and agriculture, but the quantitative principles governing their growth and architecture remain poorly understood. The ‘forward problem’ of what root forms ... -
Model selection in time series by Deep Learning
(Master thesis, 2020-06-30)In this thesis, we will explore the use of deep learning techniques for model selection in time series. We compare the results from this with more traditional approaches for model selection, namely the Akaike and Bayesian ... -
Model Spaces in Riemannian and Sub-Riemannian Geometries
(Master thesis, 2018-06-27)The development of Riemannian geometry has been highly influenced by certain spaces with maximal symmetry called model spaces. Following in the footsteps of Klein's Erlangen program, model spaces fit with the approach of ... -
Modeling a 3-D multiscale blood-flow and heat-transfer framework for realistic vascular systems
(Journal article; Peer reviewed, 2022)Modeling of biological domains and simulation of biophysical processes occurring in them can help inform medical procedures. However, when considering complex domains such as large regions of the human body, the complexities ... -
Modeling and discretization of flow in porous media with thin, full-tensor permeability inclusions
(Journal article; Peer reviewed, 2021)When modeling fluid flow in fractured reservoirs, it is common to represent the fractures as lower-dimensional inclusions embedded in the host medium. Existing discretizations of flow in porous media with thin inclusions ... -
