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 ... -
GCD sums and complete sets of square-free numbers

GCD sums from Poisson integrals and systems of dilated functions
(Journal article; Peer reviewed, 2015) -
Gender prediction on Norwegian Twitter accounts
(Master thesis, 2015)In this thesis, methods for predicting the gender of Norwegian Twitter accounts were investigated. Through Twitterâ s public APIs, various account information is available. Tweets (text), personal descriptions, friends ... -
General order conditions for stochastic partitioned Runge–Kutta methods
(Journal article; Peer reviewed, 2017)In this paper stochastic partitioned Runge–Kutta (SPRK) methods are considered. A general order theory for SPRK methods based on stochastic B-series and multicolored, multishaped rooted trees is developed. The theory is ... -
General practitioners ending their practice and impact on patients' health, healthcare use and mortality: a protocol for national registry cohort studies in Norway, 2008 to 2021
(Peer reviewed; Journal article, 2023)Introduction Continuous general practitioner (GP) and patient relations associate with positive health outcomes. Termination of GP practice is unavoidable, while consequences of final breaks in relations are less explored. ... -
General practitioners retiring or relocating and its association with healthcare use and mortality: a cohort study using Norwegian national data
(Journal article; Peer reviewed, 2024) -
Generalizations of Loday’s assembly maps for Lawvere’s algebraic theories
(Peer reviewed; Journal article, 2023)Loday’s assembly maps approximate the K-theory of group rings by the K-theory of the coefficient ring and the corresponding homology of the group. We present a generalisation that places both ingredients on the same footing. ... -
Generalized iterated-sums signatures
(Journal article; Peer reviewed, 2023)We explore the algebraic properties of a generalized version of the iterated-sums signature, inspired by previous work of F. Király and H. Oberhauser. In particular, we show how to recover the character property of the ... -
Generating series for networks of Chen–Fliess series
(Peer reviewed; Journal article, 2021)Consider a set of single-input, single-output nonlinear systems whose input–output maps are described only in terms of convergent Chen–Fliess series without any assumption that finite dimensional state space models are ... -
Generative Adversarial Networks for Seismic Interpretation
(Master thesis, 2020)Arbeidsprosesser der tolkning av seismikk inngår, er en nødvendig del av prosjekter der olje- og gassforekomster oppdages. Selv om nylige fremskritt i forskningen rundt dyp læring har gjort det mulig å forenkle noe av ... -
Generative Adverseriale Nettverk (GAN) utvidelser og anvendelser innen bildeprosessering og generering
(Master thesis, 2019)Når menneskehjernener prosesserer input fra sansene er de i stand til å unastrengt forestille seg nye instanser og scenarioer fra bare en liten mengde inputopplevelse. Generative Adverseriale Nettverk (GAN) klarer til en ... -
Generators and representability in triangulated categories
(Doctoral thesis at NTNU;2014:241, Doctoral thesis, 2014) -
A Generic Construction of Tightly Secure Password-Based Authenticated Key Exchange
(Peer reviewed; Journal article, 2023)We propose a generic construction of password-based authenticated key exchange (PAKE) from key encapsulation mechanisms (KEM). Assuming that the KEM is oneway secure against plaintext-checkable attacks (OW-PCA), we prove ... -
Generic constructions of master-key KDM secure attribute-based encryption
(Peer reviewed; Journal article, 2023)Master-key key-dependent message (mKDM) security is a strong security notion for attribute-based encryption (ABE) schemes, which has been investigated in recent years. This line of research was started with identity-based ...
