From Bilinear Regression to Inductive Matrix Completion: A Quasi-Bayesian Analysis
(Peer reviewed; Journal article, 2023)In this paper, we study the problem of bilinear regression, a type of statistical modeling that deals with multiple variables and multiple responses. One of the main difficulties that arise in this problem is the presence ... -
From classical tilting to two-term silting
(Journal article; Peer reviewed, 2019)We survey some recent results generalizing classical tilting theory to a theory of two-term silting objects. In particular, this includes a generalized Brenner-Butler theorem, and a homological characterization of algebras ... -
From panic to planning: extending the notion of presence to create sustainable digital learning environments
(Peer reviewed; Journal article, 2021)The transition from physical learning spaces to fully digital learning environments in annus horribilis 2020 has challenged Institutions and educators in re-thinking teaching in a time of crisis. E-learning is now phasing ... -
Front Tracking for Hyperbolic Conservation Laws

Full Approximation Scheme for Reservoir Simulation
(Journal article; Peer reviewed, 2018)Simulation of multiphase flow and transport in porous rock formations give rise to large systems of strongly coupled nonlinear equations. Solving these equations is computationally challenging because of orders of magnitude ... -
Full implicit WENO scheme for two phase flow in reservoir simulation
(Master thesis, 2014)This master thesis studies the use of essentially non-oscillatory schemes for the spatial discretization in a full implicit two-phase flow model used to solve flow and transport in porous media. The implicit model is based ... -
Fully Homomorphic Encryption
(Master thesis, 2015)I 2009 presenterte Craig Gentry det første krypteringssystemet som klarte å utføre vilkårlig mange homomorfe operasjoner, og i prosessen lagde han også en framgangsmåte på hvordan man konstruerer et slikt system. I denne ... -
Fully Homomorphic Encryption
(Master thesis, 2017)In this paper we consider fully homomorphic encryption based on the learning with errors problem. We present the problem as introduced by Oded Regev in 2009 and explain a simple public key cryptosystem based on it. We show ... -
Fully homomorphic encryption with applications to electronic voting
(Doctoral theses at NTNU;2018:33, Doctoral thesis, 2018) -
FULLY INHOMOGENEOUS MULTIPLICATIVE DIOPHANTINE APPROXIMATION OF BADLY APPROXIMABLE NUMBERS
(Journal article; Peer reviewed, 2021)We establish a strong form of Littlewood's conjecture with inhomogeneous shifts, for a full-dimensional set of pairs of badly approximable numbers on a vertical line. We also prove a uniform assertion of this nature, ... -
Functional Encryption for Inner Product Functionality
(Master thesis, 2022)Denne oppgaven inneholder konstruksjon av funksjonelle krypteringsalgoritmer for mindre generelle funksjoneller, men som enda er uttrykksfulle nok for praktiske scenarier. Oppgaven er avgrenset til å kun bruke indre produkt ... -
Functional form for covariates in parametric accelerated failure time models using nonparametric exponential regression
(Master thesis, 2019)Denne oppgaven undersøker hvordan funksjonell formen til en potensielt misspesifisert kovariat i en akselerert levetids modell kan bli estimert ved hjelp av to forskjellige metoder anvendt på Cox-Snell residualene til ... -
Functional Toll-like receptors in primary first-trimester trophoblasts
(Journal article; Peer reviewed, 2014)Toll-like receptors (TLRs) are an important part of the body's danger response system and crucial for initiating inflammation in response to cellular stress, tissue damage, and infections. Proper placental development is ... -
Gabor duality theory for Morita equivalent C*-algebras
(Journal article; Peer reviewed, 2020)The duality principle for Gabor frames is one of the pillars of Gabor analysis. We establish a far-reaching generalization to Morita equivalence bimodules with some extra properties. For certain twisted group C∗-algebras, ... -
Gabor frames for rational functions
(Peer reviewed; Journal article, 2022)We study the frame properties of the Gabor systems G(g;α,β):={e2πiβmxg(x−αn)}m,n∈Z. In particular, we prove that for Herglotz windows g such systems always form a frame for L2(R) if α,β>0, αβ≤1. For general rational ... -
Gal-type GCD sums beyond the critical line
(Journal article; Peer reviewed, 2016) -
GANs enabled super-resolution reconstruction of wind field
(Peer reviewed; Journal article, 2020)Atmospheric flows are governed by a broad variety of spatio-temporal scales, thus making real-time numerical modeling of such turbulent flows in complex terrain at high resolution computationally unmanageable. In this ... -
Gaussian Gabor frames, Seshadri constants and generalized Buser-Sarnak invariants
(Peer reviewed; Journal article, 2023)We investigate the frame set of regular multivariate Gaussian Gabor frames using methods from Kähler geometry such as Hörmander’s - estimate with singular weight, Demailly’s Calabi–Yau method for Kähler currents and a ... -
Gaussian Markov Models for Adaptive Smoothing
(Master thesis, 2010)In this thesis, we study Gaussian Markov random field representation of the non-homogenous integrated Wiener process, for the purpose of doing adaptive smoothing of temporal data. We demonstrate that these representations ...
