Robustifying Bayesian Hierarchical Models Using Intuitive Prior Elicitation
(Doctoral theses at NTNU;2021:215, Doctoral thesis, 2021) -
Robustness in supply chain management and design
(Master thesis, 2010)We have studied a supply chain for delivering biomass to heating plants where there are uncertainty in demand. Design of such supply chains considers finding the optimal terminal structure and an optimal inventory policy. ... -
Robustness of screening designs with a small number of runs
(Doctoral theses at NTNU;2019:162, Doctoral thesis, 2019) -
Rock Classification Using Multivariate Analysis of Measurement While Drilling Data: Towards a Better Sampling Strategy
(Journal article; Peer reviewed, 2018)Measurement while drilling (MWD) data are gathered during drilling operations and can provide information about the strength of the rock penetrated by the boreholes. In this paper MWD data from a marble open-pit operation ... -
The Role of Fourier Series in Mathematics and in Signal Theory
(Journal article; Peer reviewed, 2021)This paper presents a praxeological analysis, based on ATD (Anthropological Theory of the Didactic), of the topic of Fourier series, as this topic is introduced and used in mathematics and in electrical engineering, more ... -
The role of gentle algebras in higher homological algebra
(Peer reviewed; Journal article, 2022)We investigate the role of gentle algebras in higher homological algebra. In the first part of the paper, we show that if the module category of a gentle algebra Λ contains a d-cluster tilting subcategory for some d≥2 , ... -
Romlig interpolering av nedbør
(Master thesis, 2006)I denne oppgaven brukes enkel kriging til å interpolere nedbørsmålinger med tidsoppløsning ett døgn hentet fra 28 nedbørsstasjoner som befinner seg på og omkring Hardangervidda. Historiske tidsserier fra nedbørsstasjonene ... -
Root Systems, Cluster Algebras and Triangulations of a Regular n-gon
(Master thesis, 2010)This thesis introduces the concepts of root systems, quivers, Dynkin diagrams, triangulation of polygons and cluster algebra. The main goal is to find a connection between all these topics. -
Rotating shaft's non-linear response statistics under biaxial random excitation, by path integration
(Journal article; Peer reviewed, 2018)The response of rotating shaft to random excitations is of practical concern for various rotor type engine design applications, with high level of potential external forces of stochastic nature. Authors have studied ... -
Rotations in Factor Analysis
(Bachelor thesis, 2022)Denne oppgaven vil omhandle faktoranalyse med hovedfokus på faktormodellens rotasjoner. Rotasjoner brukes både for å kunne trekke slutninger og for å bedre tolke dataene. I denne sammenheng vil vi se på kriteriene som er ... -
The S p k , n –local stable homotopy category
(Peer reviewed; Journal article, 2023) -
Saddlepoint approximated methods for computing p-values in score tests
(Master thesis, 2023)I denne oppgaven presenteres, både teoretisk og ved hjelp av eksempler, to alternative metoder for å regne p-verdier i en score test i motsetning til å anta en normalfordeling på score-statistikken. Vi presenterer en dobbel ... -
Saddlepoint approximations to score test statistics in logistic regression for analyzing genome-wide association studies
(Peer reviewed; Journal article, 2023)We investigate saddlepoint approximations of tail probabilities of the score test statistic in logistic regression for genome-wide association studies. The inaccuracy in the normal approximation of the score test statistic ... -
Sammenhenger mellom elevers forestillinger om forståelse i matematikk og undervisningen de erfarer
(Master thesis, 2010)I masteroppgaven fokuseres det på elevers forestillinger om forståelse, og på matematikkundervisning. Målet med studien er å få dypere innsikt i sammenhenger mellom elevers forestillinger om forståelse i matematikk, og ... -
Sammenhenger mellom elevers motivasjon for matematikk og den undervisningen de erfarer
(Master thesis, 2011)Studien har til hensikt å undersøke elevers motivasjon for matematikk. Mer spesifikt hvilke sammenhenger det kan være mellom elevenes målorientering i matematikk og den undervisningspraksisen de erfarer i faget. Studiens ... -
Sammenligning og prediksjon av gassmålinger.
(Master thesis, 2009)Denne oppgaven utarbeider en metode for å estimere ankomsttider til gass basert på en sammenligning av tidsrekker. Disse tidsrekkene består av målinger av ulike egenskaper til gassen ved innløp og utløp av et rør. Volumflyt ... -
Sampling and periodization of generators of Heisenberg modules
(Journal article; Peer reviewed, 2019)This paper considers generators of Heisenberg modules in the case of twisted group C∗-algebras of closed subgroups of locally compact abelian (LCA) groups and how the restriction and/or periodization of these generators ... -
Sampling decisions for energy efficient IoT sensors using conditional copula models
(Master thesis, 2021)For å gjøre IoT-sensorer mer energieffektive, undersøkes bruk av avhengighetsstrukturer for å redusere samplingsfrekvensen. I denne oppgaven hvor vi ser på støynivåer i arbeidsmiljøet Koopen, er en observasjon hvert 15. ... -
Sampling design methods for making improved lake management decisions
(Journal article; Peer reviewed, 2024)The ecological status of lakes is important for understanding an ecosystem's biodiversity as well as for service water quality and policies related to land use and agricultural run-off. If the status is weak, then decisions ... -
Sampling of entire functions of several complex variables on a lattice and multivariate Gabor frames
(Peer reviewed; Journal article, 2019)We give a general construction of entire functions in d complex variables that vanish on a lattice of the form = A(Z + iZ)d for an invertible complex-valued matrix. As an application, we exhibit a class of lattices of ...
