Reliability testing based on deterioration measurements
(Dr.ingeniøravhandling, 0809-103X; 1988:32, Doctoral thesis, 1988)In traditional reliability life testing and accelerated life testing, usally only the failure mode and the lifetime upon failure or censoring, are recorded. The information obtained from such testing may be signicantly ... -
Reliable Genetic Correlation Estimation via Multiple Sample Splitting and Smoothing
(Peer reviewed; Journal article, 2023)In this paper, we aim to investigate the problem of estimating the genetic correlation between two traits. Instead of making assumptions about the distribution of effect sizes of the genetic factors, we propose the use of ... -
Renormalisation group for multiple zeta values
(Journal article; Peer reviewed, 2018)Calculating multiple zeta values at arguments of any sign in a way that is compatible with both the quasi-shuffle product as well as meromorphic continuation, is commonly referred to as the renormalisation problem for ... -
Renormalization of stochastic continuity equations on Riemannian manifolds
(Peer reviewed; Journal article, 2021) -
Repeatability in a multiphase pipe flow case study
(Peer reviewed; Journal article, 2021)A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an ... -
Representability of the local motivic Brouwer degree
(Peer reviewed; Journal article, 2022)We study which quadratic forms are representable as the local degree of a map f : An → An with an isolated zero at 0, following the work of Kass and Wickelgren who established the connection to the quadratic form of Eisenbud, ... -
Representasjoner av delvis ordnede mengder
(Bachelor thesis, 2020)Oppgaven introduserer representasjoner av delvis ordnede mengder og setter dem i sammenheng med representasjoner av kogger. Disse representasjonene korresponderrer med matriserepresentasjoner av delvis ordnede mengder ... -
Representation Learning for Semi-Supervised Time Series Classification
(Master thesis, 2021)Tidsrekke-klassifisering har med tiden blitt et tema av stor interesse og brukes ofte i viktige applikasjons-domener som for eksempel medisin og finans. Klassifisering av tidsrekker krever ofte en stor mengde med data som ... -
Representation Schemes for Finitely Generated Groups
(Master thesis, 2022)Repræsentationsrummet for en endeligt genereret gruppe over et legeme k kan ses som et punkt på et affint k-skema. Der er en kategorisk ækvivalens mellem affine k-skemaer og kommutative k-algebraer, hvilket vil sige, at ... -
Representation theory of Artin algebras and finite graded trees
(Master thesis, 2020)Dette arbeidet diskuterer representasjonsteorien for artinske algebraer med fokus på de nesten-splitte sekvensene. Først introduserer vi Nakayama-algebraer, Auslander-algebraer og Auslander-Reiten-kogger. Deretter undersøker ... -
Representation Theory of Geigle-Lenzing Complete Intersections

Representations and Character Varieties of Frieze groups
(Master thesis, 2022)Oppgaven omhandler representasjoner av frieze gruppene med en og to genearatorer i den generelle lineære gruppen over et vektorrom komplekst endelig dimensjonalt vektorrom V. Disse gruppene er den uendelige sykliske gruppen, ... -
Representativity Results in Motivic Degree Theory
(Master thesis, 2020)Denne masteroppgaven studerer en metode beskrevet av Kass og Wickelgren som tar et polynom med et isolert nullpunkt i origo og produserer et element i Grothendieck-Witt-ringen. Vi studerer først litt teori om bilineære ... -
Reservoir Simulation in Heterogeneous and Fractured Reservoirs
(Doctoral theses at NTNU;2018:165, Doctoral thesis, 2018)Summary of the thesis This thesis addresses simulation of flow and transport of fluids and fluid components in heterogeneous and fractured porous media. Reservoir simulation is a key component in several engineering ... -
Residuals and Functional Form in Accelerated Life Regression Models
(Master thesis, 2011)This thesis examines misspecifed log-location-scale regression models. Particularily how the models' Cox Snell residuals can be used to infer the functional form of possibly misspecified covariates in the regression. Two ... -
Resonances and Constructions of Fatou-Bieberbach Maps
(Master thesis, 2016)We study and analyze a proof of a theorem by Rosay and Rudin on the Fatou-Bieberbach method of constructing biholomorphic images of Cn in Cn, starting with an automorphism with an attracting xed point. We thoroughly ... -
Resource Allocation in Radio Networks by Graph Coloring and Non-Smooth Optimization
(Master thesis, 2018)The number of devices connected to the internet is rapidly increasing and the demand for higher bandwidth is likely to increase in the future. In this thesis we will look at methods for channel allocation and signal strength ... -
Resource-Constrained Project Scheduling for the Mass Relocation Problem
(Master thesis, 2022)Anleggsmaskiner står for en femtedel av klimagassutslippene i bygg- og anleggsbransjen i Norge, og tilbringer opptil 40 % av arbeidsdagen på tomgang som følge av venting og dårlig planlegging. Bruk av prosjektplanlegging ... -
Return Codes from Lattice Assumptions
(Master thesis, 2022)Vi presenterer en fremgangsmåte for å lage returkoder for et gitter-basert elektronisk valgsystem. For et valgsystem med fire kontrollkomponenter og kommunikasjon i to runder oppnår protokollen vår en total kommunikasjonsstørrelse ... -
A revised implicit equal-weights particle filter
(Peer reviewed; Journal article, 2019)Particle filters are fully nonlinear data assimilation methods and as such are highly relevant. While the standard particle filter degenerates for high‐dimensional systems, recent developments have opened the way for new ...
