Structure-Preserving Schemes for Stochastic Differential Equations
(Master thesis, 2022)I denne oppgaven betraktes en klasse med implisitte Runge–Kutta-metoder (RK-metoder) som kalles Hamiltonian Boundary Value Methods (HBVMs). Disse metodene er spesielt godt egnet til å løse kanoniske Hamiltonske systemer; ... -
Student active learning in a two campus organisation
(Peer reviewed; Journal article, 2020)Higher education is facing disruptive changes in many fields. Students wants to have the option of learning anywhere, anytime and in any format. Universities need to develop and deliver to future students a complete learning ... -
Student's reflections as a tool for self-regulated learning in a formative assessment practice
(Journal article; Peer reviewed, 2019) -
Students' motivation and ownership in a cross-campus and online setting.
(Peer reviewed; Journal article, 2023)This study focuses on student motivation and ownership of learning in a team-based learning environment that is situated in a cross-campus and online context. Data were collected through semi-structured interviews from 12 ... -
Study programme driven engineering education: interplay between mathematics and engineering subjects
(Peer reviewed; Journal article, 2022)This paper presents a report from an early phase of the project Mathematics as a Thinking Tool. The primary goal of this project is to increase engineering students’ perception of the relevance of mathematics by developing ... -
Studying dilemmas of mathematics teaching in Southern Africa
(Peer reviewed; Journal article, 2022)Background: Learners in many countries in sub-Saharan Africa are underperforming in important subjects such as mathematics, and research in these contexts tends to focus on the lack of resources, insufficient teacher ... -
Stumpons are non-conservative traveling waves of the Camassa–Holm equation
(Peer reviewed; Journal article, 2022)It is well-known that by requiring solutions of the Camassa–Holm equation to satisfy a particular local conservation law for the energy in the weak sense, one obtains what is known as conservative solutions. As conservative ... -
Subcategory Classifications in Tensor Triangulated Categories
(Master thesis, 2011)It is known that the thick tensor-ideal subcategories in a tensor triangulated cate-gory can be classified via its prime ideal spectrum.We use this to provide new proofs of two well-known classifications theorems:that of ... -
Subcategory structures, Grothendieck groups and higher homological algebra
(Doctoral theses at NTNU;2023:113, Doctoral thesis, 2023) -
Success-rate Estimation for Side Channel Analysis
(Master thesis, 2021)Denne masteroppgaven utforsker teori og teknikker innenfor side-kanals-angrep og side-kanals-analyse. Først definerer vi den matematiske modellen for lekkasje, og hva angrep-scenarioet er i side-kanals-angrep i form av ... -

Superconvergent patch recovery and a posteriori error estimation technique in adaptive isogeometric analysis
(Journal article; Peer reviewed, 2016)Highlights • A posteriori error estimation methodology for adaptive isogeometric analysis using LR B-splines is developed. • Superconvergent patch recovery of gradient field on adaptive meshes is developed. • Algorithm for ... -
Support Varieties for Finite Dimensional Algebras
(Master thesis, 2016)We give a presentation of the theory of support varieties for finite dimensional algebras A using the Hochschild cohomology ring. Our presentation is especially focused on the finite generation hypotheses an algebra must ... -
Support varieties for finite tensor categories: Complexity, realization, and connectedness
(Journal article; Peer reviewed, 2021)We advance support variety theory for finite tensor categories. First we show that the dimension of the support variety of an object equals the rate of growth of a minimal projective resolution as measured by the ... -
Support varieties—an axiomatic approach
(Journal article; Peer reviewed, 2019)We provide an axiomatic approach for studying support varieties of objects in a triangulated category via the action of a tensor triangulated category, where the tensor product is not necessarily symmetric. This is illustrated ... -
Support Vector Machines on Riemannian Manifolds
(Master thesis, 2022)Støttevektormaskiner er nyttige verktøy brukt til binærklassifikasjon av datasett på Hilbertrom. I noen applikasjoner derimot, slik som å klassifisere hippocampuser til mennesker med schizofreni eller separare hjernesignaler ... -
Surface wave predictions in weakly nonlinear directional seas
(Journal article; Peer reviewed, 2017)We have employed laboratory and numerical experiments in order to investigate propagation of waves in both long and short-crested wave fields in deep water. For long-crested waves with steepness, ϵ = kcac = 0.1 (a fairly ... -
Surfaces moving by Mean Curvature.
(Master thesis, 2016)We use a level-set method to describe surfaces moving by mean curvature. The interesting partial differential equation $u_t=|\nabla u| \text{div}\left(\frac{\nabla u}{|\nabla u|}\right)$ arises. In this thesis, we prove ... -
Surrogatbasert optimering ved bruk av kunstige nevrale nettverk - Identifikasjon av lønnsomme O&M strategier for offshore vindfarmer gjennom stokastiske simuleringer
(Master thesis, 2016)Kostnader tilknyttet drift- og vedlikeholdsoperasjoner utgjør en stor andel av kostnadene for offshore vindparker. Reduksjon av slike kostnader er essensielt for å gjøre energikilden mer konkurransedyktig. Strategier for ... -
Survey of numerical methods for the Korteweg de Vries equation.
