An adaptive solution strategy for Richards' equation
(Journal article; Peer reviewed, 2023)Flow in variably saturated porous media is typically modeled by the Richards equation, a nonlinear elliptic-parabolic equation which is notoriously challenging to solve numerically. In this paper, we propose a robust and ... -
Addressing class imbalance in deep learning for acoustic target classification
(Journal article; Peer reviewed, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -
Admissibility conditions for Riemann data in shallow water theory
(Journal article; Peer reviewed, 2020)Consideration is given to the shallow-water equations, a hyperbolic system modeling the propagation of long waves at the surface of an incompressible inviscible fluid of constant depth. It is well known that the solution ... -
Advection Upscaling for Heat Transport in Fractured Geothermal Reservoir
(Master thesis, 2018-06-20)The main objective in this thesis is to give numerical solution for advection term of heat transport equation in fractured geothermal reservoir. To get better insight in the fracture influence on the processes we will ... -
Algebra i første klasse
(Master thesis, 2015-10-12)Oppgaven handler om algebra i første klasse. Hva er tidlig algebra og hvordan kan vi undervise på en slik måte at vi utvikler elevenes algebraiske tenkning? Tidlig algebra er ikke at vi underviser skolealgebra tidligere, ... -
Algebra i norske lærebøker. En analyse av tre lærebøker for 8. trinn
(Master thesis, 2024-06-03)Denne masteroppgaven undersøker presentasjonen og struktureringen av algebra i tre utvalgte norske lærebøker i matematikk for 8.trinn. Motivasjonen for studien stammer fra de vedvarende utfordringene norske elever møter i ... -
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?
(Master thesis, 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 ... -
An algorithm for internal morging of two subsets with small extra storage requirements.
(Department of Applied Mathematics report;50, Research report, 1974-09) -
Algoritmisk tenkning og kreativitet
(Master thesis, 2023-06-01)Den raske teknologiutviklingen har ført til at det stadig stilles nye krav til befolkningens kompetanse og ferdigheter. Algoritmisk tenkning og kreativitet anses som essensielle ferdigheter i det 21.århundre. Gjennom ... -
Alterations in auditory brain stem response distinguish occasional and constant tinnitus
(Journal article; Peer reviewed, 2022)BACKGROUND. The heterogeneity of tinnitus is thought to underlie the lack of objective diagnostic measures. METHODS. Longitudinal data from 20,349 participants of the Swedish Longitudinal Occupational Survey of Health ... -
Altered collective mitochondrial dynamics in the Arabidopsis msh1 mutant compromising organelle DNA maintenance
(Journal article; Peer reviewed, 2022)Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be ... -
Alternative læringsmåter for derivasjon i R1 - en komparativ analyse
(Master thesis, 2016-06-01)I denne masteroppgaven har jeg studert elever som har arbeidet med derivasjon i matematikk R1. Formålet har vært å sammenligne to alternative læringsmåter med tradisjonell oppgaveregning, med tanke på læringsutbytte på ... -
An Introduction to Riemann Surfaces
(Master thesis, 2023-06-01)Riemann surfaces are an important topic in both mathematics and physics. This thesis serves as an introduction to the basics of Riemann surfaces. -
Analyse av undervisningsopplegg med undersøkende matematikk
(Master thesis, 2017-07-26)I denne masteroppgaven ser jeg på hvilken effekt undersøkende matematikk kan ha på elevers holdninger til faget med hovedvekt på motivasjon. Prosjektene har blitt gjennomført med ungdomsskoleelever ved Stiftelsen ... -
Analysis and Approximation of Coupled 1D-3D Flow Models
(Doctoral thesis, 2020-03-18)In this thesis, we consider a specific instance of mixed-dimensional partial differential equations (PDEs) commonly referred to as the coupled 1D-3D flow model. The model itself consists of the Poisson equation defined on ... -
Analysis and Numerics of strongly degenerate Convection-diffusion Problems Modelling sedimentation-consolidation Processes

Analysis of Control Volume Heterogeneous Multiscale Methods for Single Phase Flow in Porous Media
(Peer reviewed; Journal article, 2014)The standard approximation for the flow-pressure relationship in porous media is Darcy's law that was originally derived for infiltration of water in fine homogeneous sands. Ever since there have been numerous attempts to ... -
Analysis of left truncated data with an application to insurance data
(Master thesis, 2009-06-02)This thesis discusses different ways of analysing left truncated data when the lower bound itself is a stochastic variable. We will consider the possible dependence between the variable of interest and the truncating ... -
Analysis of multi-beam sonar echos of herring schools by means of simulation
(Doctoral thesis, 2013-05-31)The synchronized behavior of large schools of fish can be a fascinating sight and has caught the attention of researchers for decades. Schools of thousands, or even millions of fish can seemingly function as a single entity, ...
