(Master thesis / Masteroppgave, 2023)This thesis discusses self-similar fractals, more specifically different symmetries on self-similar fractals. We build the fractal space as a collection of compact subsets of a complete metric space. Further, we add IFS ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)A conceptual variable is any variable defined by a person or by a group of persons. Such variables may be inaccessible, meaning that they cannot be measured with arbitrary accuracy on the physical system under consideration ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)We prove that any symplectic automorphism of finite order on a manifold of type OG6 acts trivially on the Beauville–Bogomolov–Fujiki lattice and that any birational transformation of finite order acts trivially on its ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2011)Sustained pressure overload leads to compensatory myocardial hypertrophy and subsequent heart failure, a leading cause of morbidity and mortality. Further unraveling of the cellular processes involved is essential for ...

(Master thesis / Masteroppgave, 2008)In the last decade we have seen a tremendous growth in the issuance of derivatives linked to the credit risk of an individual, or a pool of obligors. While some have been around for a while, some are relatively new. One ...
-
(Master thesis / Masteroppgave, 2008)This thesis treats traffic as flow in static and dynamic networks. This may be any kind of traffic; cars, information etc. Two flows are of particular interest: The system optimum, which minimizes total travel time for all ...
-
(Research report / Forskningsrapport, 2004)The paper shows how Monte Carlo methods can be improved significantly by conditioning on a suitable variable or vector. In particular this principle is applied to system reliability evaluation. Different choices of variables ...

(Master thesis / Masteroppgave, 2019)Conventional differential gene expression analysis by methods such as SAM (Chu et al., 2001), student’s t-test and Empirical Bayes (Efron et al., 2001) often searches for statistically significant genes without considering ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Background Identifying gene interactions is a topic of great importance in genomics, and approaches based on network models provide a powerful tool for studying these. Assuming a Gaussian graphical model, ...
-
(Master thesis / Masteroppgave, 2018)The recent results on non-uniqueness of the Euler equations, all based on the theory developed in the papers by Camillo De Lellis and László Székelyhidi Jr., are believed to be connected to the theory of turbulent fluid ...

-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2019)Tchebycheffian splines are smooth piecewise functions where the different pieces are drawn from extended Tchebycheff spaces. They are a natural generalization of polynomial splines and can be represented in terms of an ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We consider Tchebycheffian spline spaces over planar T-meshes and we study their dimension. We show that the structure of extended Tchebycheff spaces allows us to fully generalize the dimension upper bounds known in the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Background Common genetic variants have been shown to modify BRCA1 penetrance. The aim of this study was to validate these reports in a special cohort of Norwegian BRCA1 mutation carriers that were selected ...

(Research report / Forskningsrapport, 2006)We consider a matrix approximation problem arising in the study of entanglement in quantum physics. This notion represents a certain type of correlations between subsystems in a composite quantum system. The states of a ...
