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 ... -
Revisiting Practical and Usable Coercion-Resistant Remote E-Voting
(Peer reviewed; Journal article, 2020)In this paper we revisit the seminal coercion-resistant e-voting protocol by Juels, Catalano and Jakobsson (JCJ) and in particular the attempts to make it usable and practical. In JCJ the user needs to handle cryptographic ... -
Rewriting results sections in the language of evidence
(Journal article; Peer reviewed, 2021)Despite much criticism, black-or-white null-hypothesis significance testing with an arbitrary P-value cutoff still is the standard way to report scientific findings. One obstacle to progress is likely a lack of knowledge ... -
Rickard's Morita theorem for derived categories
(Master thesis, 2019)Vi gir, i full detalj, to ulike bevis for Rickards moritateorem for deriverte kategorier. I det første beviset bruker vi et modifisert dobbeltkjedekompleks for å konstruere en ekvivalens mellom de deriverte kategoriene ... -
Riemannian Optimization for Deep Learning
(Master thesis, 2022)Sentrale konsepter og strukturer i riemannsk optimering presenteres og diskuteres for å gi en uavhengig behandling av Riemannian gradient descent-metoden (RGD). Egenskaper ved RGD diskuteres og sammenliknes med de av ... -
Riesz bases of exponentials for finite unions of intervals
(Master thesis, 2022)I denne oppgaven studerer vi Riesz-basiser av eksponentialfunksjoner for rommet $L^2(\Omega)$, der $\Omega \subset \bb{R}^d$. Hovedfokuset i oppgaven er å presentere Kozma og Nitzan sitt bevis for at det finnes en Riesz-basis ... -
Riesz bases of exponentials, Meyer's quasicrystals and bounded remainder sets
(Doctoral thesis at NTNU;2015:259, Doctoral thesis, 2015) -
Riesz projection and bounded mean oscillation for Dirichlet series
(Peer reviewed; Journal article, 2022)We prove that the norm of the Riesz projection from L∞(Tn) to Lp(Tn) is 1 for all n≥1 only if p≤2, thus solving a problem posed by Marzo and Seip in 2011. This shows that Hp(T∞) does not contain the dual space of H1(T∞) ... -
Right Gröbner Basis Theory and Systems of Equations Over Algebras
(Bachelor thesis, 2023)Målet med denne bachelor-oppgaven er å gi en metode for å finne løsninger av homogene systemer av lineære ligninger over veialgebraer ved bruk av høyre Gröbnerbasis-steori. Den vil introdusere tosidige Gröbnerbasiser og ... -
Rigidity of twisted groupoid Lp-operator algebras
(Peer reviewed; Journal article, 2023)In this paper we study the isomorphism problem for reduced twisted group and groupoid Lp-operator algebras. For a locally compact group G and a continuous 2-cocycle σ we define the reduced σ-twisted Lp-operator algebra Fp ... -
Riparian vegetation provides crucial shelter for resting otters in a human-dominated landscape
(Journal article; Peer reviewed, 2019)The riparian vegetation belt is one of the few remaining structures that provide coverage for wildlife in many anthropogenic landscapes. It provides shelter for many species and functions as corridors for dispersal. However, ... -
Risk Factors for Breast, Uterine and Ovarian Cancer: A competing Risks Analysis
(Master thesis, 2011)A competing risks situation arises when a unit can fail due to several distinct failure types. In a competing risk situation, standard techniques from survival analysis may lead to incorrect and biased results. In this ... -
Risk Prediction of Cardiovascular Disease with Statistical Learning Methods
(Master thesis, 2021)I denne oppgaven ser vi på potensialet for bruk av metoder fra statistisk læring til å beregne risikoen for hjerte- og karsykdommer, ved å ta i bruk data fra Helseundersøkelsen i Trøndelag, HUNT. Hovedmålet med oppgaven ... -
Road works ahead: the journey of an innovative cross-campus hybrid learning space navigating higher education institutions’ organizational setbacks
(Journal article; Peer reviewed, 2024)The most recent UN publication on Sustainable Development Goals (SDGs), which covers issues related to socioeconomic, environmental, and technological development on a global scale towards 2030, has expanded its focus to ... -
Robust Modelling of Additive and Non-additive Variation with Intuitive Inclusion of Expert Knowledge
(Peer reviewed; Journal article, 2020)We propose a novel Bayesian approach that robustifies genomic modeling by leveraging expert knowledge (EK) through prior distributions. The central component is the hierarchical decomposition of phenotypic variation into ... -
Robust nonlinear Newton solver with adaptive interface-localized trust regions
(Journal article; Peer reviewed, 2019)The interplay of multiphase flow effects and PVT behavior encountered in reservoir simulations often gives strongly coupled nonlinear systems that are challenging to solve numerically. In a sequentially implicit method, ... -
