Sammenhenger mellom koder, matroider, grafer og simplisielle komplekser
(The University of Bergen, 2008)Denne masteroppgaven handler hovedsakelig om å studere sammenhenger mellom ulike em ner innen algebra og kombinatorikk. De matematiske konseptene som studeres, er lineære koder, matroider, grafer og simplisielle komplekser, ...Master thesis 
Sampling error distribution for the ensemble Kalman filter update step
(Springer, 20110706)In recent years, data assimilation techniques have been applied to an increasingly wider specter of problems. Monte Carlo variants of the Kalman filter, in particular, the ensemble Kalman filter (EnKF), have gained ...Peer reviewedJournal article 
Scene Reconstruction Using Level Sets and Graph Cuts
(The University of Bergen, 20090717)Master thesis 
Scroll codes over curves of higher genus
(Springer, 2010)We construct linear codes from scrolls over curves of high genus and study the higher support weights di of these codes. We embed the scroll into projective space Pk1 and calculate bounds for the di by considering the ...Journal articlePeer reviewed 
Semiparametric model selection for copulas
(The University of Bergen, 20130603)This thesis will consider the performance of the crossvalidation copula information criterion, xvCIC, in the realm of finite samples. The theory leading to the xvCIC will be outlined, and an analysis will be conducted ...Master thesis 
Sequential Data Assimilation in High Dimensional Nonlinear Systems
(The University of Bergen, 20111021)Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ...Doctoral thesis 
Sequential Monte Carlo Methods for Bayesian Filtering
(The University of Bergen, 2008)Master thesis 
Sequestration of Carbon in Saline Aquifers Mathematical and Numerical Analysis
(The University of Bergen, 20040430)The work in this thesis focuses equally on two main topics. The first of these subjects deals with development of criteria for monotonicity of con trol volume methods. These methods are important and frequently used ...Doctoral thesis 
Sigma coordinate pressure gradient errors and the basin problem
(The University of Bergen, 20100415)This work will focus on how the internal pressure gradient errors affect the numerical instability in idealised ocean basins. The nature of the errors will be investigated and discussed. First, in Chapter 1, the ocean model ...Master thesis 
Simplified models for numerical simulation of geological CO2 storage
(The University of Bergen, 20170203)Carbon capture and storage (CCS) is a proposed strategy to reduce global emissions of greenhousegases. The basic principle is to capture CO2 from power generation or other industrial activities and inject it into deep ...Doctoral thesis 
Simulating spatial and temporal varying CO2 signals from sources at the seafloor to help designing riskbased monitoring programs
(Wiley, 201601)Riskbased monitoring requires quantification of the probability of the design to detect the potentially adverse events. A component in designing the monitoring program will be to predict the varying signal caused by an ...Journal article 
A simulation workflow for largescale CO2 storage in the Norwegian North Sea
(Springer, 201606)Largescale CO2 injection problems have revived the interest in simple models, like percolation and verticallyaveraged models, for simulating fluid flow in reservoirs and aquifers. A series of such models have been ...Journal article 
Simulations of multibeam sonar echos from schooling individual fish in a quiet environment
(Acoustical Society of America, 201212)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 ...Journal articlePeer reviewed 
Simulering av torsk (Gadus Morhua) sin reaksjon på fartøystøy
(The University of Bergen, 2000)Master thesis 
Skadebeløpsmodellering i skadeforsikring
(The University of Bergen, 20090601)I oppgaven modelleres skadegrader for skip med lognormalfordeling og Paretofordeling. I tillegg tar den for seg en ny sammenlått lognormalParetofordeling, og tilpasser de samme dataene til denne fordelingen. Skadegradene ...Master thesis 
Skipped spawning in Northeast Arctic haddock Melanogrammus aeglefinus
(InterResearch, 20150422)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. ...Journal article 
Skriving i matematikk. Hva skriver elevene? En studie av elevenes fagspråk i matematikk 2P med eksempler fra emnet funksjoner.
(The University of Bergen, 20170726)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 de ...Master thesis

(The University of Bergen, 2003)Master thesis 
Solute transport in aquifers with evolving scale heterogeneity
(Tipografia Universitatii Ovidius, 2015)Transport processes in groundwater systems with spatially heterogeneous properties often exhibit anomalous behavior. Using firstorder approximations in velocity fluctuations we show that anomalous superdiffusive behavior ...Journal article 
Solution strategies for nonlinear conservation laws
(The University of Bergen, 20150821)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 ...Doctoral thesis
