An Investigation of Second-Order Finite Volume Methods for Field-scale Reservoir Simulation
(PhD thesis UiS;, Doctoral thesis, 2024)This thesis focuses on improving the accuracy of numerical simulation of flow in subsurface reservoirs by using second-order finite volume methods. The first-order finite volume method, commonly used in reservoir simulation, ... -
Involutions of Quadrics
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-07-09)In the introductory chapter, we will explain briefly what all this work is about. First is worthy to mention that the most included area is algebraic geometry, which of course is a combination of algebra and linear algebra. ... -
Konvergens av Fourier rekker i Hilbert rom - en introduksjon til sampling teori.
(Master thesis, 2021)Klassisk kalkulus som omhandler studie av kontinuerlig forandring kan spores helt tilbake til 1600 tallet. Derimot mangler klassisk kalkulus evnen til å tilstrekkelig transformere naturlige prosesser som lyd, radiobølger ... -
Kortspillet SET og dets underliggende matematikk
(Bachelor thesis, 2021)SET er et høyt priset kortspill hvor hvert kort har objekter med forskjellig fyll, farge og fasong. Målet med spillet er å finne SET som består av tre kort hver som følger en bestemt regel for hvordan de kan slås sammen ... -
Kumada-Corriu coupling in synthesis of PAHs
(Master thesis, 2022)The thesis explores the Kumada-Corriu coupling reaction as a possible handle to further functionalize PAHs. The starting material used was different types of triflate bearing PAHs. An attempt at preparing phenanthren-9-yl ... -

Lattice Monte Carlo simulation and phase transitions in scalar field theories
(Masteroppgave/UIS-HF-IMF/2019;, Master thesis, 2019-06-15)The cubic anisotropy model is a simple scalar field theory with a phase transition of either first- or second order depending on the values of its parameters, with similarities to the electroweak phase transition that ... -
Lattice study of static quark-antiquark interactions in dense quark matter
(Peer reviewed; Journal article, 2019-05)In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation. To this end we compute Polyakov line correlation functions and determine ... -
Learning the nonlinear flux function of a hidden scalar conservation law from data
(Peer reviewed; Journal article, 2023-10)Nonlinear conservation laws are widely used in fluid mechanics, biology, physics, and chemical engineering. However, deriving such nonlinear conservation laws is a significant and challenging problem. A possible attractive ... -
Left-Invariant Pseudo-Riemannian Metrics on Lie Groups
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020)n differential geometry and mathematical physics, there is interest in left-invariant pseudo-Riemannian metrics on Lie groups. We learn and review Lie theory, representation theory, geometric invariant theory, and differential ... -
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The two-helix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... -
