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
(Master thesis, 2018)Recurrent Neural Networks (RNNs) have shown great success in sequence-to-sequence processing due to its ability to retain memory while incrementally processing sequence elements. It has become a fundamental algorithm for ... -
Tolerance Limit Communication Schemes and Nowcasting for Resource Constrained Sensor Networks - Utilizing NWP, Temporal and Spatial Dependencies for a Temperature Sensor Network at Spitsbergen
(Master thesis, 2018)In this thesis we consider resource constraint sensor networks that communicates with a fusion center. If communication and/or energy resources are limited, is it desirable to keep the number of transmissions from a sensor ... -
