Quantification of Reliability Performance: Analysis Methods for Safety Instrumented System
(Master thesis, 2013)The reliability performance of a safety instrumented system (SIS) can be determined by severalanalytical methods, such as simplified formulas, fault tree analysis and Markov analysis. Thesemethods are mentioned in annex B ... -
Quantifying Predictive Uncertainty in Artificial Neural Networks
(Master thesis, 2021)To metoder for å konstruere Bayesianske nevrale nettverk, MC Dropout og SGVB, er implementert og anvendt på et reelt datasett levert av det norske E\&P selskapet Aker BP. Datasettet består av brønndata hentet fra 34 brønner ... -
Quantile based modeling of diurnal temperature range with the five-parameter lambda distribution
(Peer reviewed; Journal article, 2022)Diurnal temperature range is an important variable in climate science that canprovide information regarding climate variability and climate change. Changesindiurnaltemperaturerangecanhaveimplicationsforhydrology,humanhealthand ... -
Quantitative genetic modeling and inference in the presence of nonignorable missing data
(Journal article; Peer reviewed, 2014)Natural selection is typically exerted at some specific life stages. If natural selection takes place before a trait can be measured, using conventional models can cause wrong inference about population parameters. When ... -
Quantitative Unique Continuation and Eigenvalue Bounds for the Laplacian
(Doctoral theses at NTNU;2021:285, Doctoral thesis, 2021)I denne avhandlingen skal vi studere flere aspekter ved laplaceoperatoren, spesielt med hensyn på egenverdier og egenfunksjoner. En stor del av avhandlingen er dedikert til kvantitativ unik utvidelse ulikheter for harmoniske ... -
Quantum Harmonic Analysis on Lattices and Gabor Multipliers
(Peer reviewed; Journal article, 2020)We develop a theory of quantum harmonic analysis on lattices in R2d. Convolutions of a sequence with an operator and of two operators are defined over a lattice, and using corresponding Fourier transforms of sequences and ... -
Quantum harmonic analysis on locally compact groups
(Journal article; Peer reviewed, 2023)On a locally compact group we introduce covariant quantization schemes and analogs of phase space representations as well as mixed-state localization operators. These generalize corresponding notions for the affine group ... -
Quasi Monte Carlo Methods For Hyperbolic Conservation Laws With Uncertain Initial Data
(Master thesis, 2016)We consider solving stochastic hyperbolic conservation laws with a quasi Monte Carlo method based on Sobol sequences. As far as we are aware, no one has done any research on this specific combination before. We extend an ... -
Quasi-linear functionals : theory and applications
(Doctoral thesis, 2001) -
Quasi-Static & Dynamic Numerical Modeling of Full Scale NREL 5MW Wind Turbine
(Journal article; Peer reviewed, 2017)Simulations of the National Renewable Energy Laboratory (NREL) 5MW wind turbine under quasi-static Multiple Reference Frame (MRF) and dynamic Sliding Mesh Interface (SMI) methodologies are presented. Two reference zone ... -
The quasi-static plasmonic problem for polyhedra
(Peer reviewed; Journal article, 2022)We characterize the essential spectrum of the plasmonic problem for polyhedra in R3. The description is particularly simple for convex polyhedra and permittivities ϵ<−1. The plasmonic problem is interpreted as a spectral ... -
Questioning questioning: The "why" and "how" of mathematics
(Master thesis, 2021)Utdannere og lærere er alltid på utkikk etter nye måter å forbedre sin undervisningskompetanse og metoder. Gjennom bruk av teknologi har vi utvidet utdanningsfeltet gjennom de siste tiårene med innovative og unike måter å ... -
Quipu Quivers and Nakayama Algebras with Almost Separate Relations
(Journal article; Peer reviewed, 2023)A Nakayama algebra with almost separate relations is one where the overlap between any pair of relations is at most one arrow. In this paper we give a derived equivalence between such Nakayama algebras and path algebras ... -
Quivers and admissible relations of tensor products and trivial extensions
(Master thesis, 2011)We show how to find quotients of path algebras isomorphic to tensor products, triangular matrix algebras and trivial extensions. -
Quivers, Gröbner bases, and tensor products
(Master thesis, 2022)Vi presenterer teori for Gröbner-basis i algebraer med multiplikativ basis, og spesielt for Gröbner-basis i vei-algebraer. Vi viser hvordan man kan konstruere tensorproduktet $\Lambda \otimes_K \Gamma$ av algebraer $\Lambda$ ... -
R1-elevers begrepsbilde av bevis i geometri - En studie av R1-elevers syn på bevis i geometri, og samspillet mellom begrepsbilder av bevis og argumentasjon
(Master thesis, 2018)Denne studien tar for seg hvordan R1-elevers begrepsbilde av bevis ser ut i geometri, hvordan elevene argumenterer i geometri, og hvilken sammenheng det er mellom elevers begrepsbilde av bevis og hvordan de argumenterer. ... -
Radical cube zero self injective algebras and support varieties
(Doctoral thesis at NTNU;2015:157, Doctoral thesis, 2015) -
Railway condition monitoring applying the continuous and discrete wavelet transforms
(Master thesis, 2020)Den diskrete og den kontinuerlige bølgetransformasjonen er anvendt på geometrimålinger som en metode for å overvåke sporgeometri i den danske jernbanens sporvekslinger. Geometrimålinger samles regelmessig for hele ... -
Rapid Seismic Inversion for Isolated Singularities
(Master thesis, 2008)Thin layers can cause problems in inversion algorithms as the material parameters and the thickness of the layer are inseparable. Here a thin layer model is developed where a thin sand layer embedded in shale is considered ... -
Rational local systems and connected finite loop spaces
(Peer reviewed; Journal article, 2021)Greenlees has conjectured that the rational stable equivariant homotopy category of a compact Lie group always has an algebraic model. Based on this idea, we show that the category of rational local systems on a connected ...
