A Stochastic Model of Portfolio Returns Based on the Heath-Jarrow-Morton Framework
(Master thesis, 2021)Denne oppgaven foreslår en metode for stokastisk modellering av investeringsporteføljer bestående av aksjer og risikofrie nullkupongobligasjoner. Først brukes Heath-Jarrow-Morton-rammeverket til å modellere utviklingen til ... -
A Study and Comparison of First and Second Order Cellular Automata with Examples
(Master thesis, 2010)This thesis will give an introduction to the concepts of cellular automata and higher order cellular automata, and go through several examples of both. Cellular automata are discrete systems of cells in an n-dimensional ... -
A Study of Dispersive Evolution Equations with Nonlocal Nonlinearities
(Master thesis, 2015)In this thesis we consider a nonlinear-nonlocal equation of Whitham type. We prove the local well-posedness for our equation in the fractional Sobolev space by using the Picard Lindelöf existence theorem to prove the ... -
A Study of higher order Cellular Automata with Examples
(Master thesis, 2008)Cellular automata are discrete dynamical systems which are practical to use for simulations. Higher order cellular automata are a natural extension of cellular automata, and are expected to be a useful way of improving ... -
A study of regression models for count data, with applications to salmon lice data
(Master thesis, 2023)Den norske lakseoppdrettsindustrien står overfor en betydelig utfordring med forekomst av lakselus (Leopeohtheirus salmonis). Lakselusen skader b˚ade villaks og oppdrettslaks ved å redusere vekstraten deres og til slutt ... -
A study of the Empirical Interpolation Method for solving Partial Differential Equations
(Master thesis, 2014)In this thesis the Empirical Interpolation Method (EIM) and the possibility of solving Partial Differential Equations (PDE) using this method are studied. The Empirical Interpolation Method is used to find a polynomial ... -
A study of the three-body problem in the realm of equivariant differential geometry
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:33, Doctoral thesis, 2011) -
A Study on Soccer Prediction using Goals and Shots on Target
(Master thesis, 2015)In this thesis I have developed a model for result prediction in soccer. The model is based on chances created being modeled as a Poisson process while goals scored is seen as a result of first creating chances and then ... -
A Supervised Sliding Window Approach for Change Point Detection in Multivariate Time Series
(Master thesis, 2020)Dette arbeidet gjennomfører multivariat change point-deteksjon ved hjelp av kunstige nevrale nettverk. Hovedbidraget til denne masteroppgaven var å implementere en sliding vindumetode som evaluerer alle sub-sekvenser av ... -
A survey of freshwater fishes and their macroparasites in the Guanacaste Conservation Area (ACG), Costa Rica
(NINA rapport;635, Research report, 2010)Freshwater fish were collected mainly by electrofishing in 27 localities in rivers and streams within the Area de Conservacion Guanacaste in northwestern Costa Rica, in June 1998 (rainy season), February 1999 and March ... -
A theoretical and empirical assessment of probabilistic multiple choice tests
(Master thesis, 2017)In this thesis, the probabilistic multiple choice test is analysed empirically and theoretically. It is suggested as an alternative to the traditional multiple choice test. The probabilistic multiple choice test has a long ... -
A Thousand Variations of Prêt à Voter
(Master thesis, 2019)This thesis is about the cryptographic voting protocol Prêt à Voter. This is a protocol that has been used in elections and could be applied to more in the future, whether it be electronic or traditional elections. Some ... -
A Three-Dimensional Finite Element Poisson Solver for Monte Carlo Particle Simulators
(Master thesis, 2018)A finite element Poisson solver for the calculation of the three-dimensional electric field in self-consistent particle simulations has been implemented in Fortran and integrated into an existing Monte Carlo simulator for ... -
A time-series model for estimating temporal variation in phenotypic selection on laying dates in a Dutch great tit population
(Journal article; Peer reviewed, 2019)1. Temporal and spatial variation in phenotypic selection due to changing environmental conditions is of great interest to evolutionary biologists, but few existing methods estimating its magnitude take into account the ... -
A toolbox for fitting complex spatial point process models using integrated nested Laplace approximation (INLA)
(Journal article; Peer reviewed, 2012) -
A verifiable shuffle for the GSW cryptosystem
(Journal article; Peer reviewed, 2019)This paper provides the first verifiable shuffle specifically for fully homomorphic schemes. A verifiable shuffle is a way to ensure that if a node receives and sends encrypted lists, the content will be the same, even ... -
Abstract Homotopy Theory of Smooth Manifolds
(Bachelor thesis, 2023)I denne oppgaven presenterer vi konstruksjonen av en homotopi teori for glatte mangfoldigheter på en måte som ligner Morel og Voevodskys konstruksjon av $\mathbb{A}^1$-homotopi teorien for skjemaer. Dette er basert på ... -
Accelerated Smoothing and Construction of Prolongation Operators for the Multiscale Restricted-Smoothed Basis Method on Distributed Memory Systems
(Master thesis, 2016)During the last two decades, several multiscale solvers have been developed in an attempt to reduce the computational cost of reservoir simulations. One such method is the recently proposed and promising multiscale ... -
Accelerating multiscale simulation of complex geomodels by use of dynamically adapted basis functions
(Journal article; Peer reviewed, 2019)A number of different multiscale methods have been developed as a robust alternative to upscaling and as a means for accelerated reservoir simulation of high-resolution geomodels. In their basic setup, multiscale methods ... -
Accounting for dynamics in self-optimizing control
(Journal article; Peer reviewed, 2019)Self-optimizing control focuses on minimizing the steady-state loss for processes in the presence of disturbances by holding selected controlled variables at constant set-points. The loss can further be reduced by controlling ...
