(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)As modern biotechnologies advance, it has become increasingly frequent that different modalities of high-dimensional molecular data (termed “omics” data in this paper), such as gene expression, methylation, and copy number, ...

(Research report / Forskningsrapport, 2010)We study optimal timing of irreversible investment decisions under return and time uncertainty. The considered models are formulated as maximization problems of the expected present value of the exercise payoff, where the ...

(Master thesis / Masteroppgave, 2014)In this thesis we study a class of irreversible, stochastic investment models where the optimal strategy can be computed exactly. The optimal strategy is always to invest just enough to keep the investment process outside ...

(Master thesis / Masteroppgave, 2022)Elliptic curves are used in post-quantum cryptography, where two parties can use compositions of low-degree isogenies to establish a shared secret. There are several forms for representing elliptic curves, and different ...
-
(Master thesis / Masteroppgave, 2020)\textit{Isogeny graphs} are a type of graphs, where the vertices represent elliptic curves and the edges represent isogenies. I will examine some of the structures of these graphs in this thesis. It turns out that the ...

(Master thesis / Masteroppgave, 2018)The field of compressive sensing is a modern field in applied mathematics which receives a lot of attention. In this thesis, we will give some insight into the iterative algorithms used in compressive sensing. We will study ...

(Master thesis / Masteroppgave, 2015)Reaction-Diffusion equations arise in many models in biomedical computing. One of these areas are models for the calcium dynamic in the heart cells. As the terms in reaction-diffusion equations can be solved separately ...
-
(Research report / Forskningsrapport, 2004)In this paper we obtain existence and uniqueness of solutions of forward stochastic differential equations driven by compensated Poisson random measures. To this end, an Itô-Ventzell formula for jump processes is proved ...
