Degenerate Convection-Diffusion Equations and Implicit Monotone Difference Schemes
(Department of Applied Mathematics report, Research report, 1998-03) -
A Dense Gas Model of Combined Transports and Distributions of Solutes in the Interstitium including Steric and Electrostatic Exclusion Effects, and Comparison with Experimental Data
(Master thesis, 2010-05-27)Mathematical modeling of physiological fluid systems is regarded as an important tool for further understanding of circulatory properties. The interstitium is a fluid filled space outside the cells in the body, and all ... -
Derivation and numerical solution of fully nonlinear and fully dispersive water wave model equations
(Doctoral thesis, 2017-06-09)The water wave theory is a classical part of Fluid Mechanics. It has a long scientific history with a great number of mathematical results [10, 32]. The first studies in this field were done by Stokes in 1847 [34]. He ... -
Derivation of Boussinesq's shoaling law using a coupled BBM system
(Peer reviewed; Journal article, 2013-03-14)This paper is focused on finding rules for waveheight change in a solitary wave as it runs up a slowly increasing bottom. A coupled BBM system is used to describe the solitary waves. Expressions for energy density and ... -
Derived equivalences of canonical covers of hyperelliptic and Enriques surfaces in positive characteristic
(Peer reviewed; Journal article, 2019)We prove that any Fourier–Mukai partner of an abelian surface over an algebraically closed field of positive characteristic is isomorphic to a moduli space of Gieseker-stable sheaves. We apply this fact to show that the ... -
Derived Logarithmic Hochschild Homology
(Master thesis, 2018-06-27) -
A description of daphnicle dynamics based on kinetic theory: Attempts at analogue-modelling of swarming and behaviour of Daphnia
(Department of Applied Mathematics report, Research report, 2001-06) -
Design of a monitoring program in a varying marine environment
(Master thesis, 2015-09-14)In this thesis we develop methods for optimal design of a monitoring program for offshore geological CO2 storage. The goal is to find the layout of fixed chemical sensors at the seafloor that maximizes the probability of ... -
Detecting atmospheric rivers using persistent homology
(Master thesis, 2015-06-01)This master's thesis is a first investigation on the problem of seeing whether it is possible to detect atmospheric rivers using persistent homology. Two different computations are done and a basic analysis is made. In ... -
Detecting leakage of brine or CO2 through abandoned wells in a geological sequestration operation using pressure monitoring wells
(Peer reviewed; Journal article, 2011)For risk assessment, policy design and GHG emission accounting it is extremely important to know if any CO2 or brine has leaked from a geological sequestration (GS) operation. As such, it is important to understand if it ... -
Detecting Periodic Elements in Higher Topological Hochschild Homology
(Doctoral thesis, 2013-08-20) -
Detection and quantification of CO2 seepage in seawater using the stoichiometric Cseep method: Results from a recent subsea CO2 release experiment in the North Sea
(Journal article; Peer reviewed, 2021)Carbon Capture and Storage (CCS) is a potential significant mitigation strategy to combat climate change and ocean acidification. The technology is well understood but its current implementation must be scaled up nearly ... -
Determining homology of an unknown space from a sample
(Journal article; Peer reviewed, 2023)The homology of an unknown subspace of Euclidean space can be determined from the intrinsic Čech complex of a sample of points in the subspace, without reference to the ambient Euclidean space. More precisely, given a ... -
Determining individual variation in growth and its implication for life-history and population processes using the Empirical Bayes method
(Peer reviewed; Journal article, 2014-09-11)The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods ... -
Development and implementation of the generalized continuum model for transport in porous media
(Doctoral thesis, 2018-03-19)Fluid flow phenomena in porous media have always attracted a lot of attention of scientists and engineers. Attempts to quantify the average transport in homogeneous media with a simple partial differential equation with ... -
Development of robust and efficient solution strategies for coupled problems
(Doctoral thesis, 2022-10-10)Det er mange modeller i moderne vitenskap hvor sammenkoblingen mellom forskjellige fysiske prosesser er svært viktig. Disse finner man for eksempel i forbindelse med lagring av karbondioksid i undervannsreservoarer, flyt ... -
Diagnostic drama. Use of ICDAS II and fluorescence-based intraoral camera in early occlusal caries detection: A clinical study
(Journal article; Peer reviewed, 2020)Background: Early diagnosis of occlusal caries is of paramount importance for a minimally invasive approach in dentistry. The aim of the present in vivo clinical prospective study was to compare the diagnostic outcomes of ... -
Diagram spaces and multiplicative structures
(Doctoral thesis, 2022-01-14)This thesis explores diagrammatic E_n structures as models for E_n spaces. Paper A: Braided injections and double loop spaces. (Christian Schlichtkrull and Mirjam Solberg.) We consider a framework for representing ... -

Different aspects of the hodograph transform and Riemann invariants for the shallow water equations
(Master thesis, 2018-12-15)The aim of this work is to visualize irrotational long wave on a sloping beach by following the approach of Carrier and Greenspan [5]. We first derive the non-linear shallow-water equations for sloping beach and then find ...
