Analytical, combinatorial and topological properties of quadratic differentials and their applications
(Doctoral thesis, 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 ... -
Combinatorial description of jumps in spectral networks.
(Peer reviewed; Journal article, 2017)We describe a graph parametrization of rational quadratic differen- tials with presence of a simple pole, whose critical trajectories form a network depending on parameters focusing on the network topological jumps. Obtained ... -
Danning av kvervlar og frontar på sub-mesoskala i havet

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 ... -
Elevar si grafiske forståing av derivasjon - Ei kvalitativ tilnærming
(Master thesis, 2006-05)Denne oppgåva handlar om elevar si grafiske forståing av derivasjon. Målet med oppgåva har vore å få ei oversikt over elevar sitt begrepsbilete i samband med ei grafisk framstilling av den deriverte, samt sjå på samanhengen ... -
Ensemble Methods of Data Assimilation in Porous Media Flow for Non-Gaussian Prior Probability Density
(Doctoral thesis, 2015-08-28)Ensemble-based data-assimilation methods have gained fast growth since the ensemble Kalman filter (EnKF) was introduced into the petroleum engineering. Many techniques have been developed to overcome the inherent disadvantages ... -

Implementation of an MPFA/MPSA-FV Solver for the Unsaturated Flow in Deformable Porous Media
(Master thesis, 2018-06-22)The Unsaturated Flow In Deformable Porous Media (UFIDPM) plays a crucial role in several academic and industrial applications such as; cracks induced by desiccation, collapsing soils, ground movement involving expansive ... -
Lévy processes and Lévy copulas with an application in insurance
(Master thesis, 2007)This thesis discusses Lévy processes and Lévy copulas. In connection with Lévy processes we treat some of the theory behind infinitely divisible distributions, acknowledging that the two classes are equivalent.Within the ... -
A Local Streamline Eulerian-Lagrangian Method for Two-Phase Flow
(Journal article, 2000)A method for solving the saturation equation for two-phase now is presented. The method may be viewed as an operator splitting method or as an Eulerian-Lagrangian backtracking procedure or as a modi£ed method of characteristics. ... -
Long Wave Models with Application to High Speed Vessels in Shallow Water
