Close-Kin Mark-Recapture Models
(Master thesis, 2019-07-09)Close-Kin Mark-Recapture (CKMR) is a recent extension of the ordinary mark–recapture methods used to estimate animal abundance and other population parameters. Where ordinary mark–recapture only consider the subsequent ... -
Co2 trapping in sloping aquafiers: High resolution numerical simulations

Coherence for Monoidal and Symmetric Monoidal Groupoids in Homotopy Type Theory
(Doctoral thesis, 2021-12-03)Homotopy Type Theory (HoTT) is a variant of Martin-Löf Type Theory (MLTT) developed in such a way that types can be interpreted as infinity-groupoids, where the iterated construction of identity types represents the different ... -
Collective mitochondrial dynamics resolve conflicting cellular tensions: From plants to general principles
(Journal article; Peer reviewed, 2023)Mitochondria play diverse and essential roles in eukaryotic cells, and plants are no exception. Plant mitochondria have several differences from their metazoan and fungal cousins: they often exist in a fragmented state, ... -
Combinatorial description of jumps in spectral networks.
(Peer reviewed; Journal article, 2017)We describe a graph parametrization of rational quadratic differen- tials with presence of a simple pole, whose critical trajectories form a network depending on parameters focusing on the network topological jumps. Obtained ... -
Combined effects of thermohaline and atmosphere forcing on the currents at Ormen Lange
(Department of Applied Mathematics report, Research report, 2001-12) -
A combined finite element–finite volume framework for phase-field fracture
(Journal article; Peer reviewed, 2021)Numerical simulations of brittle fracture using phase-field approaches often employ a discrete approximation framework that applies the same order of interpolation for the displacement and phase-field variables. In particular, ... -
Commutability of Control Materials - Statistical Methods of Evaluation.

Comparing Maximum Likelihood and Generalized Method of Moments in Short Term Interest Rate Models
(Master thesis, 2016-02-01)In this thesis we will look at some different continuous models for predicting the short term interest rate, and focus on the method of parameter estimation in such models. A particular focus will be placed on the method ... -
A Comparison of Anthropometric Measures for Assessing the Association between Body Size and Risk of Chronic Low Back Pain: TheHUNT Study
(Peer reviewed; Journal article, 2015-10-27)Background: Previous work indicates that overweight and obese individuals carry an increased risk of experiencing chronic low back pain (LBP). It is not known, however, how the association with body size depends on the ... -
Comparison of distance measures in Multimodal registration of medical images
(Master thesis, 2011-06-14)In this thesis I have worked with medical image registration, in particular registration of multimodal images. I have tested the image registration software package FAIR developed by Jan Modersitzki, with particular focus ... -
Comparison of Iterative Solvers for Non-Symmetric Linear Systems in Porous Media Problems
(Master thesis, 2014-09-02)We investigate the performance of the IDR(s)-algorithms when solving nonsymmetric systems in porous media problems. We derive a mathematical model for the flow in porous media, and discretized this with the method known ... -
A comparison of Monte Carlo sampling methods for metabolic network models
(Journal article; Peer reviewed, 2020)Reaction rates (fluxes) in a metabolic network can be analyzed using constraint-based modeling which imposes a steady state assumption on the system. In a deterministic formulation of the problem the steady state assumption ... -
A Comparison of Two Numerical Models for Flow in Fractured Porous Media and the Impact of Fracture Intersection Cell Removal
(Master thesis, 2016-11-21)The simulation of flow and transport in fractured porous media is crucial to improve understanding and viability of geothermal energy. It is also challenging, due to complex geometries and large scale differences. In this ... -
Compositional reservoir simulation with emphasis on the IMPSAT formulation

Computational issues in parameter estimation for hidden Markov models with template model builder
(Journal article; Peer reviewed, 2023)A popular way to estimate the parameters of a hidden Markov model (HMM) is direct numerical maximization (DNM) of the (log-)likelihood function. The advantages of employing the TMB [Kristensen K, Nielsen A, Berg C, et al. ... -
Computer-aided proofs and algorithms in analysis
(Doctoral thesis, 2013-06-14)The computational power has increased dramatically since the appearance of the first computers, making them a vital tool in the analysis of dynamical systems. We present further applications of those two basic ideas, namely ... -
Computing the distance to continuous-time instability of quadratic matrix polynomials
(Journal article; Peer reviewed, 2020)A bisection method is used to compute lower and upper bounds on the distance from a quadratic matrix polynomial to the set of quadratic matrix polynomials having an eigenvalue on the imaginary axis. Each bisection step ... -
Conditioning reservoir models on vast data sets
(Doctoral thesis, 2021-09-09)History matching is a valuable process to obtain better models and a more reliable forecast in oil reservoir applications. In such processes, one conditions the simulation models on the observed data from the field. One ... -
Conforming Discretizations of Mixed-Dimensional Partial Differential Equations
(Doctoral thesis, 2018-06-01)Mixed-dimensional partial differential equations (PDEs) are coupled equations defined on connected manifolds of different dimensionalities. Two main examples of mixed-dimensional PDEs are considered in this dissertation, ...
