Vertically Averaged Models for CO2 Storage in Porous Media
(Master thesis, 2008) -
Vertically integrated models for coupled two‐phase flow and geomechanics in porous media
(Peer reviewed; Journal article, 2016-02)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 ... -
Videregåendeelevers strategier i brøkoppgaver. Hvilke deler av brøkbegrepet er synlige i strategiene?
(Master thesis, 2018-12-19)Behr, Lesh, Post & Silver (1983) mener at rasjonale tall er blant de mest komplekse og viktigste matematiske idéene barn i grunnskolen skal lære og jeg ønsket derfor å se nærmere på brøkkunnskapene til elever etter ... -

Visualisering og konkretisering av omdreiningslegemer ved bruk av Geogebra 3D og 3D-printer
(Master thesis, 2017-07-26)Digital programvare og digitale verktøy er i stadig utvikling, og matematiske programmer, som for eksempel Geogebra, gir oss mulighet til å visualisere matematikk på en enklere og raskere måte enn tidligere, både gjennom ... -
Visuelle løsningsstrategier til sannsynlighetsoppgaver - En studie av fem videregående elevers bruk av ulike visuelle løsningsstrategier i sannsynlighetsregning
(Master thesis, 2017-07-26)Denne masteroppgaven handler om elever på videregående sin bruk av visuelle løsningsstrategier i møte med sannsynlighetsoppgaver. Formålet var blant annet å undersøke hvilke ulike visuelle løsningsstrategier elever benytter ... -
Volatility modelling in time and space
(Doctoral thesis, 2020-11-06)This thesis contributes to the scientific community in several aspects. We introduce both spatial- and spatio-temporal extensions to the family of GARCH and ARMA-GARCH models and present asymptotic statistics for the quasi ... -
Volume preserving numerical integrators for ordinary differential equations
(Doctoral thesis, 2013-11-08) -
Vurdering for læring i matematikk - vurderingspraksis i 1YT i to klassar på elektrofag
(Master thesis, 2016-05-31)Denne oppgåva handlar om formativ vurdering i matematikk. I problemstillinga spør ein etter i kva grad kapittel- og lekseprøver i 1YT har ein formativ funksjon for elevar på elektrofag. Ein skil mellom formål og funksjon ... -
Water renewal in a threshold fjord: A simulation study of submerged fresh water discharge
(Master thesis, 2018-12-15)Threshold fjords are characterized by low concentrations of oxygen in the depths of the basin, caused by weak and/or infrequent exchange of the basin water. A three-dimensional ocean model, The Bergen Ocean Model (BOM), ... -
Wave breaking in long wave models and undular bores
(Master thesis, 2015-12-18)Bores are a well known phenomena in fluid mechanics, although their occurrence in nature is relatively rare. The circumstances in which they occur is usually when a tidal swell causes a difference in surface elevation in ... -
Wave breaking in the BBM-equation
(Master thesis, 2019-04-02) -
Wave Breaking in Undular Bores with Shear Flows
(Journal article; Peer reviewed, 2021)It is well known that weak hydraulic jumps and bores develop a growing number of surface oscillations behind the bore front. Defining the bore strength as the ratio of the head of the undular bore to the undisturbed depth, ... -
Wave loads on ocean infrastructure increase as a result of waves passing over abrupt depth transitions
(Journal article; Peer reviewed, 2022)Abrupt changes in water depth are known to lead to abnormal free-surface wave statistics. The present study considers whether this translates into abnormal loads on offshore infrastructure. A fully non-linear numerical ... -
Wave response to an arbitrary motion of a load on an ice plate
(Master thesis, 2022-06-22) -
Waves generated by moving loads on ice plates: Viscoelastic approximations
(Journal article; Peer reviewed, 2022)The paper investigates waves generated by the moving loads on ice plates floating on an incompressible fluid. Two different viscoelastic approximations are considered for the ice cover: A model depending on the strain-relaxation ... -
Weak solutions and convergent numerical schemes of Brenner-Navier-Stokes equations
(Research report, 2015-01-20)Lately, there has been some interest in modifications of the compressible Navier-Stokes equations to include diffusion of mass. In this paper, we investigate possible ways to add mass diffusion to the 1-D Navier-Stokes ... -
The weight spectrum of two families of Reed-Muller codes
(Journal article; Peer reviewed, 2023)We determine the weight spectra of the Reed-Muller codes RM (m− 3, m) for m ≥ 6 and RM (m − 4, m) for m ≥ 8. The technique used is induction on m, using that the sum of two weights in RM (r −1, m−1) is a weight in RM (r, ... -
Well-posedness and discretization for a class of models for mixed-dimensional problems with high-dimensional gap
(Journal article; Peer reviewed, 2021)In this work, we show the underlying mathematical structure of mixed-dimensional models arising from the composition of graphs and continuous domains. Such models are becoming popular in applications, in particular, to ... -
Well-Posedness for a Dispersive System of the Whitham-Boussinesq Type
(Journal article; Peer reviewed, 2020)We regard the Cauchy problem for a particular Whitham--Boussinesq system modeling surface waves of an inviscid incompressible fluid layer. We are interested in well-posedness at a very low level of regularity. We derive ...
