(Master thesis / Masteroppgave, 2017)The aim of this thesis is to study the convergence and smoothness of certain nonlinear interpolatory curve subdivision schemes. The emphasis will be on the iterated geometric schemes, which are extensions of the nonlinear ...

(Master thesis / Masteroppgave, 2009)Det har blitt utviklet en andre ordens ikke linær Schrödinger metode for å estimere kinematikk i irregulær sjø på endelig dyp. Hastighetspotensialet og tilhørende overflatehevning har blitt uviklet under antagelse om sakte ...

Nonlinear mixed-dimension model for embedded tubular networks with application to root water uptake (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We present a numerical scheme for the solution of nonlinear mixed-dimensional PDEs describing coupled processes in embedded tubular network system in exchange with a bulk domain. Such problems arise in various biological ...

(Research report / Forskningsrapport, 2005)We develop a notion of nonlinear stochastic integrals for hyperfinite Lévy processes, and use it to find exact formulas for expressions which intuitively are given as sums and products of functions of the increments of ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In parallel to sustainable growth in solar fraction, continuous reductions in Photovoltaic (PV) module and installation costs fuelled a profound adoption of residential Rooftop Mounted PV (RMPV) installations already ...

(Master thesis / Masteroppgave, 2023)In this thesis, we define an infinite-dimensional stochastic integral $\int XdM$ where $M$ is a hyperfinite martingale. In order to make sense of this integral we have developed some new concepts in nonstandard functional ...

(Research report / Forskningsrapport, 2003)We model spot prices in energy markets with exponential non-Gaussian Ornstein-Uhlenbeck processes. We generalize the classical geometric Brownian motion and Schwartz' mean-reversion model by introducing Lévy processes as ...
-
(Master thesis / Masteroppgave, 2012)The canonical map from the Kan subdivision of a product of two finite simplicial sets to the product of the Kan subdivisions is a simple map, in the sense that its geometric realization has contractible point inverses.

(Master thesis / Masteroppgave, 2022)Normal pressure hydrocephalus is a variant of reversible dementia. The symptoms manifest themselves in the form of urinary incontinence, gait disturbance and dementia, and it is estimated that at least 22 out of 100 000 ...
