On the Frame Property of Hermite Functions and Exploration of their Frame Sets
(Peer reviewed; Journal article, 2025)We study Gabor frames with Hermite window functions. Gröchenig and Lyubarskii provided a sufficient density condition for their frame sets, which leads to what we call the “safety region". For rectangular lattices and ... -
Ungdomsskoleelevers matematiske kyndighet knyttet til likninger
(Master thesis, 2025)I denne studien har jeg intervjuet lærere for å få et innblikk i hvilke styrker og svakheter de opplever at ungdomsskoleelever har i arbeid med likninger. Jeg har i tillegg spurt lærerne om hvilke strategier de bruker i ... -
Towards Universel TIme Series Modeling: Deep Generative Modelling and Self-Supervised Learning for TIme Series and Beyond
(Doctoral theses at NTNU;2025:157, Doctoral thesis, 2025)Time series data are found in many parts of our daily lives and across various industries. These data are crucial for important tasks such as time series classification, clustering, generation, anomaly detection, imputation, ... -
Advances and Applications of Integrated Species Distribution Models in Large-Scale Ecological Analyses
(Doctoral theses at NTNU;2025:148, Doctoral thesis, 2025)The data revolution of the 21st century has provided statistical ecologists with a wealth of data, required to estimate species distribution models. While these data are certainly necessary in estimating large-scale models, ... -
On a two-scale phasefield model for topology optimization
(Journal article; Peer reviewed, 2024)In this article, we consider a gradient flow stemming from a problem in two-scale topology optimization. We use the phase-field method, where a Ginzburg–Landau term with obstacle potential is added to the cost functional, ... -
Local area cooling versus broad area cooling for boil-off reduction in large-scale liquid hydrogen storage tanks
(Peer reviewed; Journal article, 2025)Future use of liquid hydrogen (Image 1 ) as an effective energy carrier will require elimination or minimization of hydrogen boil-off that is not utilized by demands in the value chain. The present work promotes local area ... -

Dispensed prescription medications and short-term risk of pulmonary embolism in Norway and Sweden
(Peer reviewed; Journal article, 2024)Scandinavian electronic health-care registers provide a unique setting to investigate potential unidentified side effects of drugs. We analysed the association between prescription drugs dispensed in Norway and Sweden and ... -
ASYMMETRIC TRAVELING WAVE SOLUTIONS OF THE CAPILLARY-GRAVITY WHITHAM EQUATION
(Journal article; Peer reviewed, 2024)By a bifurcation argument we prove that the capillary-gravity Whitham equation features asymmetrical periodic traveling wave solutions of arbitrarily small amplitude. Such waves exist only in the weak surface tension regime ... -
Cryptographic Primitives
(Chapter, 2024)Blockchain is a promising and growing technology for providing reliable and secure decentralized solutions. Nevertheless, it encounters many research challenges. Some of the main challenges in the blockchain are smart ... -
The Prytz connections
(Journal article; Peer reviewed, 2024)The Prytz planimeter is a simple mechanical device that historically was used to approximate areas of plane regions. It also serves as a starting point to explain topics in differential geometry and sub-Riemannian geometry. ... -
Accounting for Individual-Specific Habitat Preferences in Statistical Models of Animal Movement Data
(Bachelor thesis, 2024)Habitatvalg-funksjoner er et viktig verktøy for å modellere dyrs bevegelser og undersøke deres valg av habitat. To funksjoner det er vanlig å bruke er ressursvalg-funskjonen og stegvalg-funksjonen. Å inkludere tilfeldige ... -
The concept of study and research inquiry: A foundational approach
(Peer reviewed; Journal article, 2024)This paper outlines the concept of Study and Research Inquiry (SRI). It emphasises how SRIs facilitate the modelling of didactic praxeologies and how the dialectic of media and milieus is central to knowledge creation and ... -

The university perspective on modelling: An exploratory study
(Journal article; Peer reviewed, 2024)This paper explores the prevailing conception of mathematical modelling in university education through the lens of university textbooks. The study identifies two major conceptions of modelling: application-oriented ... -
Coefficient Estimates for Hp Spaces with 0 < p < 1
(Master thesis, 2025)Denne masteroppgaven undersøker koeffisientestimater for analytiske funksjoner i Hardy-rommene Hp på enhetsskiven D, der 0<p<1. Spesifikt studerer vi C(k,p), der C(k,p) forstås som normen til den begrensede lineære ... -

The Norm of the Backward Shift Operator on H^p
(Master thesis, 2025)I denne masteravhandlingen utforsker vi normen til "backward shift"-operatoren på Hardy-rom. Hovedresultatet er numeriske beregninger av operatornormen. Resultatet fra Brevig og Seip [1] ble brukt som for å verifisere ...
