Implementation and comparison of three isogeometric Navier–Stokes solvers applied to simulation of flow past a fixed 2D NACA0012 airfoil at high Reynolds number
(Journal article; Peer reviewed, 2015)Implementation of three different Navier–Stokes solvers in an isogeometric finite element framework is presented in this paper. The three solvers Chorin projection method and Coupled formulation , both with the Spalart–Allmaras ... -
Implementation of an optimal control solver for linear problems
(Bachelor thesis, 2023)Optimal control theory is pivotal to many fields of science, engineering, and economics, as it provides a mathematical framework to determine the control that optimizes a given measure over time. This thesis details the ... -
Implementation of the algorithm for constructing homogeneous approximations of nonlinear control systems
(Journal article; Peer reviewed, 2022) -
Implementation of the Number Theoretic Transform
(Master thesis, 2020)I denne oppgaven skriver vi om implementering av Number Theoretic Transform, NTT. NTT er en algoritme for å multiplisere polynomer kjappere. I denne oppgaven ser vi på hvordan NTT fungerer, og hvorvidt denne faktisk ... -
Implementing a Heath, Jarrow \& Morton model for estimating counterparty credit exposure in interest rate derivatives
(Master thesis, 2023)Denne oppgaven utforsker implementasjonen av en Heath, Jarrow og Morton rentemodell for å beregne motpartsrisiko assosiert med rentederivater i forskjellige perioder og markedsforhold. Modellen bruker prinsipalkomponentanalyse ... -
Implementing Lattice-Based Cryptography
(Bachelor thesis, 2022)The thesis is about implementation of LWE/MLWE encryption schemes in C++ and the use of the Number Theoretic Transform (NTT) in order to get faster mul- tiplication operations over certain rings. We explore how much speed ... -
Implications of Realistic Fracture Criteria on Crack Morphology
(Journal article; Peer reviewed, 2019)We study the effects realistic fracture criteria have on crack morphology obtained in numerical simulations with a stochastic discrete element method. Results are obtained with two criteria which are consistent with the ... -
Importance Sampling with the Integrated Nested Laplace Approximation
(Peer reviewed; Journal article, 2022)The integrated nested Laplace approximation (INLA) is a deterministic approach to Bayesian inference on latent Gaussian models (LGMs) and focuses on fast and accurate approximation of posterior marginals for the parameters ... -
Improper priors and improper posteriors
(Peer reviewed; Journal article, 2021)What is a good prior? Actual prior knowledge should be used, but for complex models this is often not easily available. The knowledge can be in the form of symmetry assumptions, and then the choice will typically be an ... -
Improved Optimization Methods For Adjoint-Based Training Of Reduced-Order Models
(Master thesis, 2022)Simulasjon av flerfasestrømninger i porøse medier er et viktig felt grunnet dets mange anvendelsesområder. Til tross for dette har beregningskostnadene ofte vært en begrensende faktor i bruken av numeriske metoder for å ... -
Improved order 1/4 convergence for piecewise constant policy approximation of stochastic control problems
(Journal article; Peer reviewed, 2019)In N. V. Krylov, Approximating value functions for controlled degenerate diffusion processes by using piece-wise constant policies, Electron. J. Probab., 4(2), 1999, it is proved under standard assumptions that the value ... -
Improvements in Everlasting Privacy: Efficient and Secure Zero Knowledge Proofs
(Journal article; Peer reviewed, 2019)Verifiable electronic voting promises to ensure the correctness of elections even in the presence of a corrupt authority, while providing strong privacy guarantees. However, few practical systems with end-to-end verifiability ... -
Improving Direct Phone Targeting through Customer Response Modeling
(Master thesis, 2021)Direkte markedsføring har som hensikt å nå en kunde personlig. Å klassifisere hvilke kunder som mest sannsynlig svarer positivt på en kampanje er en viktig oppgave innenfor direkte markedsføring. Ved å bruke maskinlæringsmetoder ... -
Improving Direct Response Modelling through Hyperparameter Optimization of Extreme Gradient Boosting and Random Forests
(Master thesis, 2022)Responsmodellering brukes i direkte markedsføring til å rangere kunder etter sannsynligheten for respons. Dette gjøres for å øke responsraten til en kampanje, og dermed øke inntektene. Denne oppgaven vil fokusere på en ... -
Improving extreme anchor tension prediction of a 10-MW floating semi-submersible type wind turbine, using highly correlated surge motion record
(Peer reviewed; Journal article, 2022)Extreme value prediction of the load-effect responses of complex offshore structures such as the floating wind turbine (FWT) is crucial in ultimate limit state (ULS) design. This paper considers two cases to understand the ... -
Improving on the Number Field Sieve
(Master thesis, 2015)We look at efficient methods for computing logarithms in finite fields of any type. To achieve this, we first develop methods for factoring integers and computing discrete logarithms in fields of prime order using algebraic ... -
Improving the Norwegian Internet Voting Protocol
(Master thesis, 2011)We have in this thesis looked at possible improvements with respect to security for the Norwegian Internet voting protocol. We have made a new protocol with independent secret keys, where all the encryptions of the votes ... -
