Theory and Applications of Conservation Laws
(Master thesis, 2014)This thesis examines the properties, applications and usefulness of the different conservation lawsin everyday life from our homes to the industry.We investigate some mathematical derivations of linear and non-linear partial ... -
Theory of didactical situations as a tool to understand and develop mathematics teaching practices
(Journal article; Peer reviewed, 2018)This article aims to discuss how the theory of didactical situations in mathematics (TDS1 ) can be used to answer research questions concerning regular teaching practices, production of resources for regular teaching, and ... -
Thermal flow in fractured porous media and operator splitting
(Master thesis, 2014)Thermal flow in fractured porous medium is an area of interest for both the oil and the geothermal energy industry. The mathematical model consists of multiple equations, often various conservation laws and constitutive ... -
Thesaurus Racks - Categorical racks and applications in the algebraic topology of Lie racks
(Master thesis, 2016)Group objects of categories have been heavily studied in a general setting, but racks are mostly treated explicitly. Since rack structures are more general than groups, this thesis aims to explore the properties of general ... -
The third Milgram--Priddy class lifts
(Peer reviewed; Journal article, 2020)Abstract: We show that the third cohomology of the finite general linear group with trivial mod 2 coefficients is non-zero. The necessarily unique non-trivial element restricts to the third Milgram–Priddy class. -
Three Approaches in Computational Geometry and Topology: Persistent Homology, Discrete Differential Geometry and Discrete Morse Theory
(Master thesis, 2011)We study persistent homology, methods in discrete differential geometry and discrete Morse theory. Persistent homology is applied to computational biology and range image analysis. Theory from differential geometry is used ... -
Three classes of quadratic vector fields for which the Kahan discretization is the root of a generalised Manin transformation

Three-dimensional internal gravity-capillary waves in finite depth
(Journal article; Peer reviewed, 2019)We consider three‐dimensional inviscid‐irrotational flow in a two‐layer fluid under the effects of gravity and surface tension, where the upper fluid is bounded above by a rigid lid and the lower fluid is bounded below by ... -
Three-dimensional Roof Surface Geometry Inference Using Remote Sensing Data
(Master thesis, 2020)I denne masteroppgaven presenterer vi en ende-til-ende maskinlæringsprosedyre for å identifisere beliggenheten, orientering og høyden til takoverflater ved hjelp av fjernmålinger (digitale overflatemodeller og/eller flyfoto). ... -
The tight groupoid of the inverse semigroups of left cancellative small categories
(Peer reviewed; Journal article, 2020)We fix a path model for the space of filters of the inverse semigroup associated to a left cancellative small category . Then, we compute its tight groupoid, thus giving a representation of its -algebra as a (full) groupoid ... -

Tightly Secure Hierarchical Identity-Based Encryption
(Peer reviewed; Journal article, 2020)We construct the first tightly secure hierarchical identity-based encryption (HIBE) scheme based on standard assumptions, which solves an open problem from Blazy, Kiltz, and Pan (CRYPTO 2014). At the core of our constructions ... -
Til evigheten -- og forbi: En kort historie om uendelighet fortalt i ZF
(Bachelor thesis, 2021)Denne oppgaven utspiller seg i det formelle systemet ZF, hvor vi konstruerer de naturlige tallene, og mer generelt ordinalene. Videre beskriver vi aritmetikken til de to tallsystemene, og til slutt konstuerer vi von Neumanns ... -
Time of admission and mortality after hip fracture – a detailed look at the weekend effect in a nationwide study of 55 211 hip fracture patients in Norway
(Journal article; Peer reviewed, 2018)Background and purpose: There are numerous studies on the weekend effect for hip fracture patients, with conflicting results. We analyzed time of admission and discharge, and the association with mortality and length of ... -
Time-Frequency Analysis Meets Quantum Harmonic Analysis
(Doctoral theses at NTNU;2021:152, Doctoral thesis, 2021)The subject of this thesis is the study of quantum harmonic analysis and timefrequency analysis, and in particular the intersection of these two fields. Quantum harmonic analysis is studied abstractly both by obtaining new ... -
Time-frequency analysis on the adeles over the rationals
(Journal article; Peer reviewed, 2019)We show that the construction of Gabor frames in with generators in and with respect to time-frequency shifts from a rectangular lattice is equivalent to the construction of certain Gabor frames for over the adeles over ... -
Time-Optimal Adaptation in Metabolic Network Models
(Peer reviewed; Journal article, 2022)Analysis of metabolic models using constraint-based optimization has emerged as an important computational technique to elucidate and eventually predict cellular metabolism and growth. In this work, we introduce time-optimal ... -
Time-series predictions with Recurrent Neural Networks - Studying Recurrent Neural Networks predictions and comparing to state-of-the-art Sequential Monte Carlo methods
