The Stability and Instability of Solitary Waves
(The University of Bergen, 2010-04-23)
Image processing, filtering and segmentation of data-sets for reservoir simulation
(The University of Bergen, 2013-10-11)
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: http://dx.doi.org/10.2118/154292-ms
Analysis of multi-beam sonar echos of herring schools by means of simulation
(The University of Bergen, 2013-05-31)
The synchronized behavior of large schools of fish can be a fascinating sight and has caught the attention of researchers for decades. Schools of thousands, or even millions of fish can seemingly function as a single entity, ...
Square-free modules and ideals: Brill–Noether theory, polarizations, and deformations.
(The University of Bergen, 2013-05-24)
Oribatid mites in a changing world
(The University of Bergen, 2011-12-09)
The main scope of this thesis is to illustrate the validity of oribatid mites as tools for palaeoecological reconstructions. Palaeoecology studies the responses of past organisms to past environmental changes. This can be ...
Nonholonomic geometry on finite and infinite dimensional Lie groups and rolling manifolds
(The University of Bergen, 2012-03-30)
Part I: We start by giving some background on the topics discussed in this thesis. The main topic of the thesis is nonholonomic geometry. In Chapter 1 we give an introduction of nonholonomic geometry in the context of ...
Derivation and numerical solution of fully nonlinear and fully dispersive water wave model equations
(The University of Bergen, 2017-06-09)
The water wave theory is a classical part of Fluid Mechanics. It has a long scientific history with a great number of mathematical results [10, 32]. The first studies in this field were done by Stokes in 1847 . He ...
Multiscale analysis of selected problems in fluid dynamics
(The University of Bergen, 2017-02-03)
The world around us is inherently multiscale. The variety of different models depending on the reference scale is particularly diverse in problems of fluid-solid systems. For those systems, the geometry, effective parameters ...
On the Relation between Surface Profiles and Internal Flow Properties in Long-Wave Models
(The University of Bergen, 2017-03-10)
In this work, we investigate the internal velocity field in a number of Boussinesq models in non-uniform situations. A coupled BBM-BBM type system of equations is derived in the assumption of water wave propagating over ...
Analytical, combinatorial and topological properties of quadratic differentials and their applications
(The University of Bergen, 2017-12-13)
Quadratic differentials ﬁrst appeared in 1930s in works of Teichmuller in connection with moduli problem for Riemann surfaces. Later it was revealed that quadratic differ- entials and their trajectories give solutions to ...
