Competition between marine osmotrophs for phosphorus and nitrogen : implications for the microplanktonic food web
(The University of Bergen, 2007-03-29)
Understanding how competition for nutrients structures the flows of C, N, P, and other elements through the microbial food web may seem central to our understanding of the role and function of this part of aquatic ...
Challenges related to storage and transfer of solar energy with a case study on long distance power transfer
(The University of Bergen, 2010-06-21)
The challenges that will be discussed in this thesis are two-fold; the problems related to trans- mission of power over long distances, and the need for energy storage, especially at night. Both of the issues are accentuated ...
Value of different data types for estimation of permeability
(The University of Bergen, 2011-06-01)
The interrelation between sensitivity, non-linearity and scale, associated with the inverse problem of identifying permeability from measurements of fluid flow, is considered. The gouverning equations for fluid flow in a ...
Fast methods to solve the pooling problem
(The University of Bergen, 2014-05-31)
In pipeline transportation of natural gas, simple network flow problems are replaced by hard ones when bounds on the flow quality are imposed. The sources, typically represented by gas wells, provide flow of unequal ...
The development and evaluation of an idealized ocean model for the Bergen Dynamic Model
(The University of Bergen, 2013-11-20)
Three idealized ocean model versions are developed for the Bergen Dynamic Model (Bedymo). All three model versions fall into the category of slab ocean models. One version is more or less a standard slab ocean model, ...
Reactive Transport in Porous Media
(The University of Bergen, 2011-08-01)
In this thesis, we show how the common equations for flow in porous media can be expanded to account for geochemical reactions. Furthermore, the complications arising when solving the new equations numerically are described ...
Multiscale simulation of flow and heat transport in fractured geothermal reservoirs
(The University of Bergen, 2013-03-04)
Plate reduction in freshwater threespine sticklebacks (Gasterosteus aculeatus) - an adaptation to a different buoyancy regime?
(The University of Bergen, 2009-03-13)
One of the striking differentiations freshwater threespine sticklebacks (Gasterosteus aculeatus) with a marine origin experiences, is a reduction in the numbers of lateral plates. This has been demonstrated to be caused ...
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 ...
Impact of diagenesis on seismic properties of siliciclastic rocks
(The University of Bergen, 2006-04-25)
