Simulations of multi-beam sonar echos from schooling individual fish in a quiet environment
(Peer reviewed; Journal article, 2012-12)A model is developed and demonstrated for simulating echosounder and sonar observations of fish schools with specified shapes and composed of individuals having specified target strengths and behaviors. The model emulates ... -
Simulering av grunne geotermiske systemer med naturlig konveksjon i borehull
(Master thesis, 2020-12-19)Introduksjon: Grunne geotermiske systemer benyttes til oppvarming og kjøling av husholdninger og større bygg. I etableringsfasen av slike systemer anvendes det modelleringsverktøy for ̊a beregne optimal dimensjonering av ... -

A singularity removal method for coupled 1D–3D flow models
(Journal article; Peer reviewed, 2019)In reservoir simulations, the radius of a well is inevitably going to be small compared to the horizontal length scale of the reservoir. For this reason, wells are typically modelled as lower-dimensional sources. In this ... -
Skadebeløpsmodellering i skadeforsikring
(Master thesis, 2009-06-01)I oppgaven modelleres skadegrader for skip med lognormalfordeling og Paretofordeling. I tillegg tar den for seg en ny sammenlått lognormal-Paretofordeling, og tilpasser de samme dataene til denne fordelingen. Skadegradene ... -
Skipped spawning in Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2015-04-22)Large interannual fluctuations in the numbers of offspring joining a teleost population are common, yet factors affecting offspring production, a key driver of fish population size and demography, are often poorly understood. ... -
Skriving i matematikk. Hva skriver elevene? En studie av elevenes fagspråk i matematikk 2P med eksempler fra emnet funksjoner.
(Master thesis, 2017-07-26)I masteroppgaven ”Skriving i matematikk. Hva skriver elevene? En studie av fagspråk i matematikk 2P med eksempler fra emnet funksjoner” fokuseres det på analyse av elevbesvarelser. Formålet med denne studien er å få økt ... -
Small data scattering for a cubic Dirac equation with Hartree type nonlinearity in $\R^{1+3}$
(Journal article; Peer reviewed, 2020)We prove that the initial value problem for the Dirac equation $(-i\gamma^\mu \partial_\mu + m) \psi= ( \frac{e^{- |x|}}{|x|} \ast ( \overline \psi \psi)) \psi \quad \text{in } \ \mathbb{R}^{1+3}$ is globally well-posed ... -
Socioeconomic and geographic differences in ablation of atrial fibrillation in Norway - a national cohort study
(Journal article; Peer reviewed, 2022)Background The aim of this study was to analyse whether there are patient related or geographic differences in the use of catheter ablation among atrial fibrillation patients in Norway. Methods National population-based ... -

Solute transport in aquifers with evolving scale heterogeneity
(Peer reviewed; Journal article, 2015)Transport processes in groundwater systems with spatially heterogeneous properties often exhibit anomalous behavior. Using first-order approximations in velocity fluctuations we show that anomalous superdiffusive behavior ... -
Solution of a non-strictly hyperbolic system modelling non-isothermal two-phase flow in a porous medium

Solution strategies for nonlinear conservation laws
(Doctoral thesis, 2015-08-21)Nonlinear conservation laws form the basis for models for a wide range of physical phenomena. Finding an optimal strategy for solving these problems can be challenging, and a good strategy for one problem may fail spectacularly ... -
Solvenskontroll ved skifting mellom ulike volatilitetsregimer
(Master thesis, 2009-06-02)Oppgåva handlar om utfordringar knytta til innføringa av Solvency 2. -
