Paper A: 2-D Visualisation of Unstable Waterflood and Polymer Flood for Displacement of Heavy Oil. Full-text not available in BORA. The published version is available at: <a href="http://dx.doi.org/10.2118/154292-ms" ...
The Stability and Instability of Solitary Waves
(The University of Bergen, 2010-04-23)
Upscaled modeling of CO2 injection and migration with coupled thermal processes
A practical modeling approach for CO2 storage over relatively large length and time scales is the vertical-equilibrium model, which solves partially integrated conservation equations for flow in two lateral dimensions. ...
Continuous Max-Flow for Image Segmentation with Shape Priors
(The University of Bergen, 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 ...
Multidimensional Fourier Transform on Sparse Grids
(The University of Bergen, 2009-06-01)
When working on multidimensional problems, the number of points needed when using a tensor product grid. This is known as the curse of dimensionality. In this thesis we propose a set of sparse grids, which can be used to ...
Detecting Periodic Elements in Higher Topological Hochschild Homology
(The University of Bergen, 2013-08-20)
Modelling Fluid Flow and Heat Transport in Fractured Porous Media
(The University of Bergen, 2013-08-27)
Flow in porous media is an important and well- researched topic in both academia and the industry. More accurate mathematical models are constantly sought after. Fractures in a porous medium can be an important cont ...
Field-case simulation of CO2-plume migration using vertical-equilibrium models
When injected in deep saline aquifers, CO2 moves radially away from the injection well and progressively higher in the formation because of buoyancy forces. Analyzes have shown that after the injection period, CO2 will ...
On Solving a Three Phase Flow Model with Capillary Forces
(The University of Bergen, 1998-07-10)
