Fast pricing of barrier options with NIG dynamics
(Master thesis, 2008)We show how we can price different barrier options very fast and accurately using numerical path integration. We will assume the underlying stock follow a NIG process. -
Fast Spatial Multi-level Models for Small Area Estimation
(Master thesis, 2023)Det foreslås en utvidelse av Besag-York-Mollié (BYM)-modellen som kan ta hensyn til romlig variasjon på flere nivåer. Multi-level modellen presenteres som en alternativ metode for nøyaktig estimering av demografiske data ... -
Fast Tensor-Product Solvers for the Numerical Solution of Partial Differential Equations: Application to Deformed Geometries and to Space-Time Domains
(Master thesis, 2010)Spectral discretization in space and time of the weak formulation of a partial differential equations (PDE) is studied. The exact solution to the PDE, with either Dirichlet or Neumann boundary conditions imposed, is ... -
The fat mass and obesity-associated (FTO) gene allele rs9939609 and glucose tolerance, hepatic and total insulin sensitivity, in adults with obesity
(Peer reviewed; Journal article, 2021)The objective of the study was to assess associations of the rs9939609 FTO allele to glucose tolerance, hepatic and total insulin sensitivity (IS) in individuals with obesity. From a low-dose hyperinsulinemic euglycemic ... -
Fault controlled pressure modelling in sedimentary basins /
(Dr. ingeniøravhandling, 0809-103X; 2000:22, Doctoral thesis, 2000)The starting point for this Dr. Ing. thesis was the requirement for models describing basin scale overpressure for use in basin modelling studies. It is necessary to identify, understand and describe both the generating ... -
Feature Learning in the Neural Collapse regime of Deep Classifiers
(Master thesis, 2023)Vi har identifisert Neural Collapse i de indre, skjulte lagene i flere typer dype nevralnett. Vi har vist at fenomenet oppstår i både fullstendig koblede nevralnett, konvolusjonsnett og residual-nett for flere datasett, ... -
Feed-forward neural networks and how to explain their predictions
(Bachelor thesis, 2021)Et kunstig feed-forward nevralt nettverk bruker lag med noder knyttet sammen av vekter til å kalkulere prediksjoner på basis av et input. Denne arkitekturer i kombinasjon med ikke lineære aktiverings funksjoner gjør at ... -
Fenchel Duality and a Separation Theorem on Hadamard Manifolds
(Peer reviewed; Journal article, 2022)In this paper, we introduce a definition of Fenchel conjugate and Fenchel biconjugate on Hadamard manifolds based on the tangent bundle. Our definition overcomes the inconvenience that the conjugate depends on the choice ... -
Fibrasjoner av Kategorier
(Master thesis, 2019)Det finnes en {\em kanonisk} modellstruktur på $\Cat$ som bruker ekvivalenser av kategorier, og vi forsøker å forstå fibrasjonene involvert. Første kapittel gir en detaljert utledning av at yonedaimbeddingen $\y : \C \to ... -
Fiducial Inference and Decision Theory

Financial modelling applied to long-horizon savings and pension products.
(Master thesis, 2007)his thesis studies financial models applied to valuation and risk measurement applicable to products in the life and pension area. Stock market theory and option pricing are described as a theoretical background. Mathematical ... -
Financial Risk, Risk Appetite and the Macroeconomic Environment
(Master thesis, 2006)This thesis seeks to establish a methodology to reveal whether the risk appetite held by investors is dependent on the macroeconomic environment and, if present, to quantify this dependency. To do so a generic model is ... -
Finding general guidelines for redesign of learning spaces
(Journal article; Peer reviewed, 2019)Higher Education is shifting from teacher-centred to student-centred practices. Such new practices ought to make today's students into active and cooperative learners and give them more relevant, real challenges and hands-on ... -
Finding Points on Elliptic Curves Modulo Composites
(Master thesis, 2010)We consider the problem of finding points on elliptic curves over the ring of integers modulo an RSA modulus. Finding points on this curve seems to be hard, and we attack the problem from three different points of view. -
Finding Small Roots of Polynomial Equations Using Lattice Basis Reduction
(Master thesis, 2009)Using the LLL-algorithm to find small roots of polynomial equations using lattice basis reduction. -
Finding topological structure in neural ensemble activity
(Doctoral theses at NTNU;2023:45, Doctoral thesis, 2023)Finding topological structure in neural ensemble activity Recent breakthroughs in electrophysiological recordings and calcium imaging have unlocked the potential for understanding how groups of neurons work together. ... -
Fine-Grained Secure Attribute-Based Encryption
(Peer reviewed; Journal article, 2021) -
Fine-Tuning BERT for Document Ranking
(Master thesis, 2021)Dokumentrangering handler om å rangere en liste dokumenter basert på en søketekst slik at de mest relevante dokumentene kommer øverst på lista. Dette brukes blant annet i søkemotorer eller vitenskapelige databaser. I denne ... -
Finite approximations of physical models over local fields
(Journal article; Peer reviewed, 2015)We show that the Schrödinger operator associated with a physical system over a local field can be approximated in a very strong sense by finite Schrödinger operators. Some striking numerical results are included at the end ... -
Finite Approximations of Quantum Systems in a Non-Archimedean and Archimedean Setting
(Doctoral thesis at NTNU;2016:212, Doctoral thesis, 2016)Approximation of quantum systems by nite dimensional quantum systems goes back to the foundation of quantum mechanics. Finite dimensional quantum systems were considered by Hermann Weyl, and were considered in much ...
