A delayed SEIR-model of the Covid-19 pandemic
(Master thesis, 2022-06-01) -
A numerical study of water exchange in sill fjords and the effect of coastal climate change
(Master thesis, 2019-05-27)The dynamics of basin water exchange in sill fjords are governed by external factors. This thesis addresses how climate change on the coast may affect the water exchange of the basin water. A three-dimensional hydrostatic ... -

Acoustic and Boundary Layer Comparisons Between Navier-Stokes and Svärd's Modified Navier-Stokes Equations
(Master thesis, 2021-12-22) -
Adaptive Multiscale Methods Based on A Posteriori Error Estimates
(Master thesis, 2010-06-01)We give an overview of different methods for solving highly heterogeneous elliptic problems with multiscale structure and no intuitive scale separation. We compare different finite element variational multiscale methods ... -
Adaptive parameterization of electric conductivity in inversion of electromagnetic data
(Master thesis, 2012-06-01)We describe a methodology developed for 3-D parameter identification, with focus on large-scale applications such as monitoring subsea oil production and geothermal systems. The methodology is designed to handle challenges ... -
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 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 ... -
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 ... -
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. -
Analysis of AMR and Other Mesh-Refinement Techniques for Inviscid Fluid Problems
(Master thesis, 2021-06-01) -
Analysis of non-linear shallow water equations discretized on Arakawa C-grids
(Master thesis, 2016-06-01)To model the behaviour of flow and waves in three dimensions, one may use the Navier-Stokes equations. These equations leads to the shallow water equations, when the depth is much smaller than the wavelength. The shallow ... -
Application of Hilbert-Huang Transform in Bearing Fault Detection
(Master thesis, 2020-03-21) -
Area rearrangement operator in discrete and continuous calculus
(Master thesis, 2024-06-03)By interpreting sums as area we construct the area rearrangement operator which looks like Φ = −x d/dx in the continuous case and φ = −x∆ in the discrete case. We explore the properties of these operators, among them how ... -
Bevis i undervising av realfagsmatematikk i vidaregåande skule
(Master thesis, 2019-06-22)Bevis har spelt ei sentral rolle i utvikling av matematikken, og kan seiast å danne grunnlaget for kvifor matematikken er som den er. Bevisa viser kvifor formlar og teorem stemmer, men dei har fleire roller utover dette; ... -
Boundary-value problems and shoaling analysis for the BBM equation
(Master thesis, 2012-02-20)In this thesis we study the BBM equation u_t+u_x+ \frac{3}{2}uu_x - \frac{1}{6} u_{xxt}= 0 which describes approximately the two-dimensional propagation of surface waves in a uniform horizontal channel containing an ... -
Boussinesq modeling of the influence of wave energy converters on nearshore circulation
(Master thesis, 2023-06-01)In Chapter 4 it was found that particle transport is much more sensitive to waves originating in the infra-gravity (IG) band. These are waves which typically have much smaller amplitudes than the typical waves seen on the ...
