Convergence of energy stable finite-difference schemes with interfaces
(Journal article; Peer reviewed, 2021)We extend the convergence results in Svärd and Nordström (2019) [7] for single-domain energy-stable high-order finite difference schemes, to include domains split into several grid blocks. The analysis also demonstrates ... -
Convergence of finite differences schemes for viscous and inviscid conservation laws with rough coefficients.

A convergent mass conservative numerical scheme based on mixed finite elements for two-phase flow in porous media
(Research report, 2017)In this work we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists on two fully coupled, non-linear equations: a degenerate parabolic equation and an elliptic ... -
Convolutional Neural Networks for Malaria Detection
(Master thesis, 2019-12-13)Together with doctors at Haukeland University Hospital in Bergen, we wanted to research how the diagnosis of malaria can be improved. We propose a method that can detect malaria parasites (Plasmodium falciparum) in microscope ... -
A copula-based multivariate hidden Markov model for modelling momentum in football
(Journal article; Peer reviewed, 2021)We investigate the potential occurrence of change points—commonly referred to as “momentum shifts”—in the dynamics of football matches. For that purpose, we model minute-by-minute in-game statistics of Bundesliga matches ... -
Copulas and Local Gaussian Correlation
(Master thesis, 2012-05-30)We are looking at copula models and dependence measures. Especially the recently developed local dependence measure called local Gaussian correlation (LGC) is presented, and its connection with the copula theory is explored. ... -
The Corrected Operator Splitting Approach Applied to a Nonlinear Advection-Diffusion Problem
(Department of Applied Mathematics report, Research report, 1997-01) -
Corrected Operator Splitting for Nonlinear Parabollic Equations
(Department of Applied Mathematics report, Research report, 1997-04) -
Corrections to Classical Kinetic and Transport Theory for a Two-Temperature, Fully lonized Plasma in Electromagnetic Fields

Cost efficient environmental survey paths for detecting continuous tracer discharges
(Peer reviewed; Journal article, 2017-07)Designing monitoring programs for detecting potential tracer discharges from unknown locations is challenging. The high variability of the environment may camouflage the anticipated anisotropic signal from a discharge, and ... -
Count time series with application to corporate defaults

Coupled effects of wave and depth-dependent current interaction on loads on a bottom-fixed vertical slender cylinder
(Journal article; Peer reviewed, 2023)The coupled effects of waves and a subsurface current on the hydrodynamic loads on offshore slender structures in coastal water regions have been examined in this paper, especially the coupling of the weak nonlinearity of ... -
Covering tour problem with varying coverage: Application to marine environmental monitoring
(Journal article; Peer reviewed, 2023)In this paper, we present a novel variant of the Covering Tour Problem (CTP), called the Covering Tour Problem with Varying Coverage (CTP-VC). We consider a simple graph 𝐺 = (𝑉 ,𝐸), with a measure of importance assigned ... -
Critical Measures and Parameter Space of Jenkins-Strebel Quadratic Differentials
(Master thesis, 2012-05-07)The thesis is devoted to applications of the theory of quadratic differentials to the problems of construction of critical measures, that provide critical values of the logarithmic energy of a charge system on the complex ... -
Crustal Conditions Favoring Convective Downward Migration of Fractures in Deep Hydrothermal Systems
(Journal article; Peer reviewed, 2023)Cooling magma plutons and intrusions are the heat sources for hydrothermal systems in volcanic settings. To explain system longevity and observed heat transfer at rates higher than those explained by pure conduction, the ... -
CSF circulation and dispersion yield rapid clearance from intracranial compartments
(Journal article; Peer reviewed, 2022-09-12)In this paper, we used a computational model to estimate the clearance of a tracer driven by the circulation of cerebrospinal fluid (CSF) produced in the choroid plexus (CP) located within the lateral ventricles. CSF was ... -
Cubical and cosimplicial descent
(Peer reviewed; Journal article, 2018)We prove that algebraic K ‐theory, topological Hochschild homology and topological cyclic homology satisfy cubical and cosimplicial descent at connective structured ring spectra along 1‐connected maps of such ring spectra. -
