Horisontkunnskap i aksjon. Om lærernes syn på relevansen av avansert matematisk kunnskap i undervisningsarbeidet
(The University of Bergen, 20180620)In this master’s thesis I have examined in which ways Norwegian secondary teachers in mathematics think they need advanced mathematical knowledge in their teaching practice, and I have discussed this against the concept ...Master thesis 
Matematikk i kjemi. Hva er så vanskelig?
(The University of Bergen, 20180620)I denne masteroppgaven har matematikk i kjemi hatt hovedfokus. Følgende forskningsspørsmål har vært grunnlag for arbeidet: • Med utgangspunkt i matematikkemner som kreves i kjemi, hvilke matematikkoppgaver viser flest ...Master thesis 
Time Series: Forecasting and Evaluation Methods With Concentration On Evaluation Methods for Density Forecasting
(The University of Bergen, 20180606)The main focus of this thesis are density forecasts and the corresponding evaluation methods. A density forecast is an estimate of the probability density of predicted values. Density forecasts and the related evaluation ...Master thesis 
Optimal design of photovoltaic power plants
(The University of Bergen, 20180530)The configuration of the photovoltaic panels is important to maximize the energy output of a photovoltaic power plant. In this thesis, I have developed an algorithm calculating the optimal solution for the design of a solar ...Master thesis 
ThetaRegularity and LogCanonical Threshold
(The University of Bergen, 20180530)The logcanonical threshold is an invariant that is widely used in modern birational geometry. It contains information regarding the singularities of sheaves of ideals. The thetaregularity index is a regularity condition ...Master thesis 
Klassestørrelsens betydning for undervisningens innhold. En sammenligning av læreres undervisningspraksis i liten og stor klasse
(The University of Bergen, 20180508)The importance of class size for the content of the teaching is a master's thesis that, using qualitative methods, tries to answer the question of how is the content of mathematics teaching in the upper secondary school ...Master thesis 
Model development for efficient simulation of CO2 storage
(The University of Bergen, 20180216)Carbon capture and storage (CCS) is an important component of several initiatives to reduce global greenhouse gas emissions by injecting and storing CO2 in underground reservoirs. Simulation technology plays an important ...Doctoral thesis 
Vertically integrated models for coupled two‐phase flow and geomechanics in porous media
(American Geophysical Union, 201602)Models of reduced dimensionality have been found to be particularly attractive in simulating the fate of injected CO2 in supercritical state in the context of carbon capture and storage. This is motivated by the confluence ...Journal article 
Data on gender contrasts in the risk of incident myocardial infarction by age. The Tromsø Study 19792012
(Elsevier, 201708)The data presented in this article relate to the research article entitled “Risk of incident myocardial infarction by gender: Interactions with serum lipids, blood pressure and smoking. The Tromsø Study 1979–2012” (Albrektsen ...Journal article 
Postinjection Normal Closure of Fractures as a Mechanism for Induced Seismicity
(American Geophysical Union, 20171004)Understanding the controlling mechanisms underlying injectioninduced seismicity is important for optimizing reservoir productivity and addressing seismicityrelated concerns related to hydraulic stimulation in Enhanced ...Journal article 
Numerical modeling of shear stimulation in naturally fractured geothermal reservoirs
(The University of Bergen, 20180322)Sheardilationbased hydraulic stimulations are conducted to create enhanced geothermal systems (EGS) from low permeable geothermal reservoirs, which are initially not amenable to energy production. Reservoir stimulations ...Doctoral thesis 
Modelling of the Shear Dilation Based Hydraulic Stimulation in Enhanced Geothermal Systems Considering Fractures in Different Scales
(EGEC, 201609)A numerical approach for modelling of shear dilation of existing fractures in hydraulic stimulation of geothermal reservoirs at low elevated pressures is presented. The fractured rock in the reservoir is modelled as ...Conference object 
Using the bottleneck distance to compare homological methods of detecting atmospheric rivers
(The University of Bergen, 20180221)Master thesis 
Algebravansker. Hva er årsaken til at elevene syns algebra er vanskelig? Er det hull i grunnleggende kunnskap og/eller misoppfatninger hos elever på videregående skole som gjør at algebra er vanskelig for dem?
(The University of Bergen, 2017)I denne oppgaven kommer det fram hva årsaken og problemer elever på videregående kan ha i algebra som gjør at de syns algebra er vanskelig, og gjør det dårlig i dette emnet. Resultatene fra TIMSS Advanced i 2015 viser at ...Master thesis 
Development and implementation of the generalized continuum model for transport in porous media
(The University of Bergen, 20180319)Fluid flow phenomena in porous media have always attracted a lot of attention of scientists and engineers. Attempts to quantify the average transport in homogeneous media with a simple partial differential equation with ...Doctoral thesis 
On the relationship between multiple porosity models and continuous time random walk
(CIMNE, 2010)We derive a multiple porosity model based on the continuous time random walk model (CTRW). In particular, we show how the parameters of the multiple porosity models relate to the transition probability function which is ...Conference object 
Fourier analysis on abelian groups; theory and applications
(The University of Bergen, 2017)Fourier analysis expresses a function as a weighted sum of complex exponentials. The Fourier machinery can be applied when a function is defined on a locally compact abelian group (LCA). The groups R, T = R / Z, Z and Z_n ...Master thesis 
Elevers roller i matematikksamtale
(The University of Bergen, 2017)Masteravhandlingen "Elevers roller i matematikksamtale" handler om hva slags roller elever har når de samtaler om matematikk med andre elever. Formålet med studien er å få en større forståelse for hvordan elever i videregående ...Master thesis 
Combinatorial description of jumps in spectral networks.
(The American Mathematical Society, 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. ...Journal article 
Analytical, combinatorial and topological properties of quadratic differentials and their applications
