ICLR 2022 Challenge for Computational Geometry & Topology: Design and Results
(Peer reviewed; Journal article, 2022)This paper presents the computational challenge on differential geometry and topology that was hosted within the ICLR 2022 workshop “Geometric and Topo- logical Representation Learning”. The competition asked participants ... -
Idealfaktorisering i Dedekindområder
(Master thesis, 2013)Vi har studert forskjellige klasser av integritetsområder og sett på noen egenskaper hos disse.Vi har definert et Dedekindområde og vist at ethvert ekte ikke-null ideal i et slikt område kan faktoriseres unikt til et produkt ... -
Idempotent Fourier multipliers acting contractively on Hp spaces
(Peer reviewed; Journal article, 2021)We describe the idempotent Fourier multipliers that act contractively on Hp spaces of the d-dimensional torus Td for d≥1 and 1≤p≤∞. When p is not an even integer, such multipliers are just restrictions of contractive ... -
Identifying expression quantitative trait loci in patients with inflammatory bowel disease
(Master thesis, 2019)Denne masteroppgaven er en pilotstudie for å undersøke forholdet mellom genotypede SNP og genuttrykket til et gen. Vi bruker genet ITGAL som et prototype-gen, og analyserer prøver fra individer med og uten kroniske ... -
Identifying Soil Heat Dynamics
(Master thesis, 2020)Vi har studert en Gaussisk prosess for å modellere varmeflyt i jord. Prosessen er den stasjonære løsningen på et lineært stokstisk system basert på varmeledningsligningen med additiv støy. Med temperaturmålinger rundt ... -
Identity Protection, Secrecy and Authentication in Protocols with compromised Agents
(Master thesis, 2009)The design of security protocols is given an increasing level of academic interest, as an increasing number of important tasks are done over the Internet. Among the fields being researched is formal methods for modeling ... -
Ikke-kommutative Sobolev-rom
(Master thesis, 2017)Først blir det essensielle av forkunnskaper introdusert. Dette inneholder den grunnleggende Hilbert C*-modulteorien, definisjonen og konstruksjonen av Moritaekvivalenser samt noen konsekvenser av dette. På disse bimodulene ... -
Ikkjedekomposerbare dekomposisjonar av nokre Quiverrepresentasjonar
(Bachelor thesis, 2020)Vi vil finne ikkjedekomposerbare dekomposisjonar av nokre quiverrepresentasjonar. For å oppnå dette definerer vi ei rekke begrep og viser til nokre av eigenskapane ved desse. Deretter konstruerar vi ein eksakt sekvens og ... -
Image Analysis Bayesian Inversion in Hidden Markov Models
(Master thesis, 2021)I denne studien blir Bayesiansk inversjon i skjulte Markov modeller brukt til å analysere bilder. Den rekursive bakvendte algoritmen, som regner ut sannsynlighetene i posterior-modellen til en Markov random profil direkte, ... -
Image recognition performed on handwritten letters using the windowed scattering transform
(Master thesis, 2017)The windowed scattering transform is an operator that is invariant to small translations, deformations and rotations. The transform can be used in conjunction with a classification algorithm to perform image recognition. ... -
Image Restoration and Super-resolution using Total Variation
(Master thesis, 2019)Hovedformålet med bildegjenoppretting er å kunne hente informasjon fra ødelagte kilder til bildedata. Hovedmålet med denne oppgaven er å undersøke en kraftig metode for bildegjenoppretting, og det er å bruke variasjonsalgoritmer ... -
The imaging of guard cells of thioglucosidase (tgg) mutants of Arabidopsis further links plant chemical defence systems with physical defence barriers
(Journal article; Peer reviewed, 2021)The glucosinolate-myrosinase system is a well-known plant chemical defence system. Two functional myrosinase-encoding genes, THIOGLUCOSIDASE 1 (TGG1) and THIOGLUCOSIDASE 2 (TGG2), express in aerial tissues of Arabidopsis. ... -
Impact of ozone treatment on dissolved organic matter in land-based recirculating aquaculture systems studied by Fourier transform ion cyclotron resonance mass spectrometry
(Peer reviewed; Journal article, 2022)In land-based recirculating aquaculture systems (RAS), the accumulation of dissolved organic matter (DOM) can have detrimental effects on water quality impacting the system performance, microbial community, and consequently ... -
Impact of urban density and building height on energy use in cities
(Journal article; Peer reviewed, 2016)Compact cities have been attributed to lower per capita energy use. However, the complexity of relationships between the elements that constitute energy consumption in the urban system is poorly understood. Little or no ... -
Imperfect Testing and its Influence on Availability of Safety Instrumented Systems
(Master thesis, 2015)Imperfect testing of SIS, its types, definitions and models that take in account its contribution to average unavailability of the system. -
Implementation and comparison of three isogeometric Navier–Stokes solvers applied to simulation of flow past a fixed 2D NACA0012 airfoil at high Reynolds number
(Journal article; Peer reviewed, 2015)Implementation of three different Navier–Stokes solvers in an isogeometric finite element framework is presented in this paper. The three solvers Chorin projection method and Coupled formulation , both with the Spalart–Allmaras ... -
Implementation of an optimal control solver for linear problems
(Bachelor thesis, 2023)Optimal control theory is pivotal to many fields of science, engineering, and economics, as it provides a mathematical framework to determine the control that optimizes a given measure over time. This thesis details the ... -
