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 ... -
Continuous Max-Flow for Image Segmentation with Shape Priors
(Master thesis, 2014-06-02)In this thesis we propose a stable method for image segmentation with shape priors. The original Chan-Vese intensity based segmentation model with regularisation term is extended to include shape prior information. We study ... -
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 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 ... -
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 ... -
Development and implementation of a tumor growth simulation tool
(Master thesis, 2023-06-01)This thesis presents the development and analysis of a mathematical model for avascular tumor growth. The model considers the influence of externally supplied nutrients as growth-promoting factors, growth-inhibiting factors ... -
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 ... -
A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(Master thesis, 2010-05-26)The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ... -
Dynamic Capillary Effects in the Simulation of Flow and Transport in Porous Media: A New Linearisation Method
(Master thesis, 2014-12-25)In this thesis mathematical models with and without dynamic capillary effects are developed to model water flow and solute transport through a porous medium. The system of equations are discretised using the finite volume ... -
Dynamic Mode Decomposition and Koopman Operator (Data-Driven Modeling of Complex Dynamical Systems)
(Master thesis, 2019-06-19)Data-driven schemes are in high demand, given the growing abundance and accessibility to large amounts of measurements from historical records, numerical simulations, and experimental data. However, despite the abundance ... -
Dynamical modeling of pathogenic bacteria in surface drinking water
(Master thesis, 2020-10-08)Dynamisk modellering av økologiske systemer har vært et interessant verktøy for å forstå samspillet mellom arter i naturen. I denne oppgaven konstruerer vi et dynamisk system for interaksjon mellom patogene bakterier og ... -
Effect of Erroneous Representation of Location and Orientation of EM Receivers for Monitoring of Submarine Petroleum Reservoirs
(Master thesis, 2009-06-02)The receivers in electromagnetic monitoring should optimally be placed exactly in the same location during every single acquisition. However, for technological and economical reasons, the receivers are currently brought ... -
Effects of thermally-dependent rock parameters on fracture reactivation
(Master thesis, 2019-07-09)The slip tendency is an important tool to measure fracture reactivation in thecontext of subsurface engineering applications. In this thesis, the effects of thermally-dependent rock parameters such as Young’s modulus on ... -
Efficient solvers for Richards' equation
(Master thesis, 2023-01-20)In this thesis we have sought to solve Richards’ equation. In time we applied a backward Euler discretization and in space we used a continuous Galerkin finite element discretization. The focal point was how to efficiently ... -
Ein kvalitativ studie av elevsamtale i gjennomføring av memoryspel med matematiske definisjonar
(Master thesis, 2022-06-30)Målet med denne studien var å sjå kva element som var framtredande i den elevsamtalen som oppstod i gjennomføring av memoryspel med matematiske definisjonar, og kva for nokre indikasjonar på læringsmoglegheiter som var ... -
