Estimation and identifiability of kinetic parameters in dynamical models of biochemical reaction networks
(Doctoral thesis, 20200218)This dissertation is a partial fulfillment of the requirements for the degree Doctor of Philosophy (PhD) at the Department of Mathematics, University of Bergen. The subject of the thesis is estimation of parameters in ... 
Estimation of AR parameters in time series with suddenly changing structure
(Statistical report no. 19, Research report, 198807) 
Estimering av permeabilitet med bruk av adaptiv parameterisering
(Master thesis, 20090717) 
etrm: Energy Trading and Risk Management in R
(Journal article; Peer reviewed, 2022)This paper introduces etrm, an R package with tools for trading and financial risk management in energy markets. Contracts for electric power and natural gas differ from most other commodities due to the fact that physical ... 
Evaluating the suitability of closekin markrecapture as a demographic modelling tool for a critically endangered elasmobranch population
(Journal article; Peer reviewed, 2022)Estimating the demographic parameters of contemporary populations is essential to the success of elasmobranch conservation programmes, and to understanding their recent evolutionary history. For benthic elasmobranchs such ... 
Evaluation of a deep neural network for acoustic classification using simulated echo sounder data
(Master thesis, 20200616)An important part of fisheries acoustics is the classification of fish species. Sound waves are transmitted through water to detect fish species, and the echoes returning from the fish are categorized to be used for fish ... 
Evolution of a narrowband spectrum of random surface gravity waves
(Journal article, 200303) 
Evolutionary inference across eukaryotes identifies universal features shaping organelle gene retention
(Journal article; Peer reviewed, 2022)Mitochondria and plastids power complex life. Why some genes and not others are retained in their organelle DNA (oDNA) genomes remains a debated question. Here, we attempt to identify the properties of genes and associated ... 
Evolving mtDNA populations within cells
(Peer reviewed; Journal article, 2019)Mitochondrial DNA (mtDNA) encodes vital respiratory machinery. Populations of mtDNA molecules exist in most eukaryotic cells, subject to replication, degradation, mutation, and other population processes. These processes ... 
Exact and Superconvergent Solutions of the MultiPoint Flux Approximation Omethod: Analysis and Numerical Tests
(Master thesis, 20140602)In this thesis we prove the multipoint flux approximation Omethod (MPFA) to yield exact potential and flux for the trigonometric potential functions u(x,y)=sin(x)sin(y) and u(x,y)=cos(x)cos(y). This is done on uniform ... 
Exact solutions for shoaling waves in shallow water
(Master thesis, 20170322)The dynamics of shallowwater waves at the surface of an inviscid and incompressible fluid over a background shear flow approaching a sloping beach are investigated. First, we derive the nonlinear shallowwater equations ... 
Exchange on dynamic encounter networks allows plant mitochondria to collect complete sets of mitochondrial DNA products despite their incomplete genomes
(Journal article; Peer reviewed, 2022)Mitochondria in plant cells usually contain less than a full copy of the mitochondrial DNA (mtDNA) genome. Here, we asked whether mitochondrial dynamics may allow individual mitochondria to ‘collect’ a full set of mtDNAencoded ... 
Existence and Uniqueness of Nonlinear, Possibly Degenerate Parabolic PDEs, with Applications to Flow in Porous Media
(Master thesis, 20170726)In the branch of mathematical analysis known as functional analysis, one mainly studies functions defined on vector spaces. For partial differential equations (PDEs), this analysis has proven to be a mighty resource of ... 
Existence and uniqueness of singular solutions for a conservation law arising in magnetohydrodynamics
(Peer reviewed; Journal article, 20181030) 
Existence of a classical solution of a parabolic PIDE associated with ruin probability
(Journal article, 20120618)In this article we will prove existence of a classical solution of the integrodifferential equation for ruin probability in finite time stated in Paulsen (2008). 
Experimental design for parameter estimation in steadystate linear models of metabolic networks
(Journal article; Peer reviewed, 202001)Metabolic networks are typically large, containing many metabolites and reactions. Dynamical models that aim to simulate such networks will consist of a large number of ordinary differential equations, with many kinetic ... 
Explicit volumepreserving splitting methods for divergencefree ODEs by tensorproduct basis decompositions
(Peer reviewed; Journal article, 20140223)We discuss the construction of volumepreserving splitting methods based on a tensor product of singlevariable basis functions. The vector field is decomposed as the sum of elementary divergencefree vector fields (EDFVFs), ... 
An Exploratory Analysis of MultiClass Uncertainty Approximation in Bayesian Convolutional Neural Networks
(Master thesis, 20181122)Neural networks are an important and powerful family of models, but they have lacked practical ways of estimating predictive uncertainty. Recently, researchers from the Bayesian machine learning community developed a ... 
Extending Whitney's extension theorem: nonlinear function spaces
(Journal article; Peer reviewed, 2021)We consider a global, nonlinear version of the Whitney extension problem for manifoldvalued smooth functions on closed domains , with nonsmooth boundary, in possibly noncompact manifolds. Assuming is a submanifold with ... 
Extreme wave runup on a steep coastal profile
(Journal article; Peer reviewed, 2020)It is shown that very steep coastal profiles can give rise to unexpectedly large wave events at the coast. We combine insight from exact solutions of a simplified mathematical model with photographs from observations at ...
