En kvalitativ studie av elevers matematiske kompetanse uttrykt i arbeid med en problemløsningsoppgave med programmering som hjelpemiddel.
(Master thesis, 2021-06-01)Hensikten med dette prosjektet var å få innsikt i hvordan elevenes matematiske kompetanse og arbeidsprosess ble påvirket gjennom bruk av en problemløsningsoppgave. Grunnet innføring av programmering i den nye læreplanen, ... -
Energieffektivitet i grunne geotermiske systemer. Modellering og analyse av systemet på Ljan skole.
(Master thesis, 2013-06-17)Grunnvarme er en stadig viktigere og mer anvendt energikilde i en verden med et økende energibehov, og det er i den forbindelse viktig å utforme systemer som kan utnytte energien på en effektiv måte. Denne oppgaven tar for ... -
Evaluation of a deep neural network for acoustic classification using simulated echo sounder data
(Master thesis, 2020-06-16)An important part of fisheries acoustics is the classification of fish species. Sound waves are transmitted through water to detect fish species, and the echoes returning from the fish are categorized to be used for fish ... -
Exact and Superconvergent Solutions of the Multi-Point Flux Approximation O-method: Analysis and Numerical Tests
(Master thesis, 2014-06-02)In this thesis we prove the multi-point flux approximation O-method (MPFA) to yield exact potential and flux for the trigonometric potential functions u(x,y)=sin(x)sin(y) and u(x,y)=cos(x)cos(y). This is done on uniform ... -
Exact solutions for shoaling waves in shallow water
(Master thesis, 2017-03-22)The dynamics of shallow-water waves at the surface of an inviscid and incompressible fluid over a background shear flow approaching a sloping beach are investigated. First, we derive the nonlinear shallow-water equations ... -
Existence and Uniqueness of Non-linear, Possibly Degenerate Parabolic PDEs, with Applications to Flow in Porous Media
(Master thesis, 2017-07-26)In the branch of mathematical analysis known as functional analysis, one mainly studies functions defined on vector spaces. For partial differential equations (PDEs), this analysis has proven to be a mighty resource of ... -
Fast Image Segmentation Using Variational Optimization Methods With Edge Detector
(Master thesis, 2014-06-02)In this work, we apply techniques in variational optimization to image segmentation. We study three different segmentation models: one is based on the active contour method, the second is based on a piecewise constant level ... -
Finite-Element Modelling of Buoyancy-Driven Flow in Natural Geothermal Systems
(Master thesis, 2010-05-27)Finite element modelling of buoyancy driven flow in geothermal systems is presented in this thesis. The main focus is on the development of a numerical modelling tool. The program developed is tested for classical benchmarks ... -

Forståelse av matematiske tekstoppgaver. Hva bør man som lærer ha tenkt gjennom når man ønsker at elevene skal jobbe med tekstoppgaver i matematikk?
(Master thesis, 2018-06-21)Denne studien tar for seg matematiske tekstoppgavers oppbygning og ser på ulike typer utfordringer elever kommer over i møte med tekstoppgaver. Utfordringene handler i stor grad om det å oversette teksten i tekstoppgaver ... -
Fourier analysis on abelian groups; theory and applications
(Master thesis, 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 ... -
Gasslekkasjar i Marine miljø
(Master thesis, 2012-06-19)I denne masteroppgåva studerast fluidstrøymingar gjennom marine sediment, og målet er å vurdere om ein enkel matematisk modell klarar å beskrive og bevare karakteristiske trekk for prosessen. Denne drøftinga vil baserast ... -
