Multipliers of the Dirichlet space
(The University of Bergen, 2009-11-20)
The topic of the thesis is the Dirichlet space of analytic functions in the unit disk and multipliers of this space. We study the elementary properties of multipliers, characterizations of multipliers, univalent multipliers ...
Tensor Induction as Left Kan Extension
(The University of Bergen, 2014-12-02)
Numerisk løsning av invers-problem ved ’Ensemble Kalman Smoother’
(The University of Bergen, 2008)
Streamline based History Matching
(The University of Bergen, 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 ...
Probability distributions of surface gravity waves during spectral changes
(Cambridge University Press, 2005-11)
Lie–Butcher series and geometric numerical integration on manifolds
(The University of Bergen, 2011-11-04)
The thesis belongs to the field of “geometric numerical integration” (GNI), whose aim it is to construct and study numerical integration methods for differential equations that preserve some geometric structure of the ...
Investigations of the Modified Navier-Stokes Equations in One Dimension
(The University of Bergen, 2014-06-02)
In this thesis we have investigated the Brenner-Navier-Stoke equations in one spatial dimension. These are a modified version of the Navier-Stokes equations, where the modification relates to a mass diffusion term. This ...
An approximate hybrid method for modeling of electromagnetic scattering from an underground target
(The University of Bergen, 2010-12-09)
The detection of a potential petroleum reservoir is achieved through inversion of electromagnetic data acquired in sea floor receivers. Inversion of electromagnetic data requires a number of repeated solves of the ...
Robust Multiscale Control-volume Methods for Reservoir Simulation
(The University of Bergen, 2012-04-30)
Geological Storage of CO2: Sensitivity and Risk Analysis
(The University of Bergen, 2014-04-10)
Geological CO2 storage has the potential to be a key technology for prevention of industrial CO2 emission into the atmosphere. A successful storage operation requires safe geological structures with large storage capacity. ...
