Stochastic unit-root processes
(Master thesis, 2016-06-01)In practice there are many types of processes that have near unit roots and are very difficult to distinguish from standard unit-root processes, given a finite sample. In our thesis we study a particular class of such ... -
Streamline based History Matching
(Master thesis, 2009-05-07)Streamline based reservoir simulation has been used with great success in the petroleum industry for decades. Fast computational speed together with the fact that sensitivities can be computed analytically along streamlines ... -
A Streamline Front Tracking Method for Two- and Three-Phase Flow Including Capillary Forces

Streamline methods for parabolic differential equations.
(Master thesis, 2008)Parabolic advection-diffusion equations arise when modelling flow in porous media. We will in this thesis discuss two different problem set-ups from which these types of equations arise. - Groundwater contamination with ... -

Stromule Geometry Allows Optimal Spatial Regulation of Organelle Interactions in the Quasi-2D Cytoplasm
(Journal article; Peer reviewed, 2023)In plant cells, plastids form elongated extensions called stromules, the regulation and purposes of which remain unclear. Here, we quantitatively explore how different stromule structures serve to enhance the ability of a ... -
A strongly degenerate convectio-diffusion Problem modeling centrifugation of flocculated Suspensions.

Students’ evaluation of academic courses: An exploratory analysis to an Italian case study
(Journal article; Peer reviewed, 2021)Students’ evaluations of teaching is a common practice in higher education institutions, with the main purpose of improving course quality and effectiveness. In this paper we would like to contribute to the existing ... -
A study in the effects of different treatments on the growth of high fluorescence virus.
(Master thesis, 2011-09-01) -
A study in Univalence
(Master thesis, 2014-06-02)In this master thesis we want to study the newly discovered homotopy type theory, and its models within mathematics. We look at models in simplicial sets, simplicial symmetric monoids, and a new category which could be ... -
A study of different interactions between solitary waves for fractional Korteweg-de Vries type equations
(Doctoral thesis, 2023-01-13)Denne avhandlingen er satt sammen av tre artikler. I den første konstruerer vi $N$-soliton løsninger for den fractional Korteweg-de Vries (fKdV) ligningen $\partial_t u - \partial_x\left(|D|^{\alpha}u - u^2 \right)=0,$ i ... -
A study of the diffusive properties of a modified compressible Navier-Stokes model
(Journal article; Peer reviewed, 2022)The aim of this study is to provide further validation for the weakly well-posed modified compressible Navier-Stokes system proposed in Svärd (Phys A 506:350–375, 2018) when applied to ideal gases. We do so by considering ... -
A study of the influence of vorticity, capillarity and slope angle on the properties of shoaling and breaking waves
(Doctoral thesis, 2021-10-28)Fluid motion and wave patterns have fascinated humans for centuries if not millennia. Water waves have been studied out of curiosity such as observing the ripples created by a stone dropped in a pond as well as practical ... -
A Study of the Modelling Error in two Operator Splitting Algorithms for porous Media Flow

A Study of the Verigin Problem with Application to Analysis of Water Injection Tests
(Department of Applied Mathematics report, Research report, 1985-03) -
A Study on Continuous Max-Flow and Min-Cut Approaches
(Chapter; Peer reviewed, 2010)We propose and investigate novel max-flow models in the spatially continuous setting, with or without supervised constraints, under a comparative study of graph based max-flow / min-cut. We show that the continuous max-flow ... -
A study on iterative methods for Richards' equation
(Peer reviewed; Journal article, 2016-04)This work concerns linearization methods for efficiently solving the Richards equation, a degenerate elliptic-parabolic equation which models flow in saturated/unsaturated porous media. The discretization of Richards’ ... -
