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 ... -
Sampling on Quasicrystals
(Master thesis, 2011)We prove that quasicrystals are universal sets of stable sampling in any dimension. Necessary and sufficient density conditions for stable sampling and interpolation sets in one dimension are studied in detail. -
SARS-CoV-2 aerosol transmission in schools: The effectiveness of different interventions
(Peer reviewed; Journal article, 2022)BACKGROUND: Indoor aerosol transmission of SARS-CoV-2 has been widely recognised, especially in schools where children remain in closed indoor spaces and largely unvaccinated. Measures such as strategic natural ventilation ... -
A scalable approach for short-term disease forecasting in high spatial resolution areal data
(Journal article; Peer reviewed, 2023)Short-term disease forecasting at specific discrete spatial resolutions has become a high-impact decision-support tool in health planning. However, when the number of areas is very large obtaining predictions can be ... -
A scalarization scheme for binary relations with applications to set-valued and robust optimization
(Peer reviewed; Journal article, 2020)In this paper, a method for scalarizing optimization problems whose final space is endowed with a binary relation is stated without assuming any additional hypothesis on the data of the problem. By this approach, nondominated ... -

Scenario tree generation for stochastic programming : cases from finance
(Dr. ingeniøravhandling, 0809-103X; 2003:55, Doctoral thesis, 2003)In recent years, stochastic programming has gained an increasing popularity within the mathematical programming community, mainly because the present computing power allows users to add stochasticity to models that were ... -
Scientific Visualization of Multidimensional Geometric Data:a Study Inspired by the Simulator BedSim of LKAB
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:100, Doctoral thesis, 2010)This work began as a joint research project between Narvik University College and the R&D Department of LKAB (www.lkab.com), an international high-tech iron ore processing company seated in Kiruna in northern Sweden. The ... -
SDElib: Creating, solving and analyzing stochastic differential equations - A program written in Python 3.5
(Master thesis, 2017)This paper is about a Python package called sdelib intended to work with stochastic differential equations (SDEs). The package can solve SDEs, estimate strong and weak orders of convergence of SDEs, and plot stability ... -
Seasonal distribution of an opportunistic apex predator (Tursiops truncatus) in marine coastal habitats of the Western Mediterranean Sea
(Peer reviewed; Journal article, 2022)Assessing the distribution of marine apex–predators is pivotal to understanding community interactions and defining management goals. However, several challenges arise in both estimates and predictions considering the ...
