Invariant variational schemes for ordinary differential equations
(Journal article, 2021)We propose a novel algorithmic method for constructing invariant variational schemes of systems of ordinary differential equations that are the Euler–Lagrange equations of a variational principle. The method is based on ... -
Invariant-preserving integrators for differential equations
(Doctoral theses at NTNU;2020:166, Doctoral thesis, 2020) -
Inverse problems for a model of biofilm growth
(Peer reviewed; Journal article, 2023)A bacterial biofilm is an aggregate of micro-organisms growing fixed onto a solid surface, rather than floating freely in a liquid. Biofilms play a major role in various practical situations such as surgical infections and ... -
Inverse scattering of two-dimensional photonic structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:68, Doctoral thesis, 2012) -
Inversion of well logs into lithology classes accounting for spatial dependencies by using hidden markov models and recurrent neural networks
(Journal article; Peer reviewed, 2021)Lithology is a crucial factor in reservoir characterization. Due to the limited availability of cores, the classes of the subsurface lithologies in boreholes need to be predicted from indirect measurements like well logs. ... -
Invertible objects in Franke's comodule categories.

Investigating GPU parallelism for discontinuous Petrov-Galerkin methods with optimal test functions
(Master thesis, 2018)We study the application of the naturally stable class of numerical methods called discontinuous Petrov-Galerkin methods with optimal test spaces, or DPG methods, focusing on their inherent complexity and potential for ... -
Investigating iterative solvers of Poisson-type equations discretized by the Two-Point Flux-Approximation scheme
(Master thesis, 2019)I denne masteroppgaven ser vi på alternative iterative løsere til MATLABs innebygde direkte løser \texttt{mldivide} for Poisson-type problemer. Løserene er testet på to forskjellige modeller som er vanlig å bruke for ... -
Investigating the Continuum Limit of a Follow-The-Leader Model with Inhomogeneous Road Conditions
(Master thesis, 2018)An investigation of the continuum limit of Follow-the-Leader model with inhomogeneous road conditions and its relation to the LWR model. In the special case when the flux function have one discontinuity that decreases the ... -
Investigating the Effect of Norwegian Policy Rate Changes on Interest Rate Risk
(Master thesis, 2022)Denne masteroppgavens hovedmål er å utforske risiko tilknyttet rentederivater. Vi tester effekten endringer i den norske styringsrenten har på risikoen ved å bruke INLA (Integrated Nested Laplace Approximation). INLA har ... -
Investigating the Phototactic Response of Salmon Lice
(Master thesis, 2019)Lakselus er en av de største utfordringene i lakseindustrien i dag ved at de forårsaker store økonomiske tap og truer dyrevelferden. Ingen av de eksisterende metodene for å redusere infeksjonsraten forårsaket av lakselus ... -
Investigation of shortened sea phase effect on salmon lice
(Master thesis, 2021)Lakselus (Leopeohtheirus salmonis) er en parasitt som påfører store økonomiske og økologiske konsekvenser for havbruksnæringen. I forsøk på å få kontroll over lakselusen tester oppdrettsnæringen ut ulike metoder og ... -
Investigation of the impact of wakes and stratification on the performance of an onshore wind farm
(Journal article; Peer reviewed, 2015)This work investigates the effects of wakes and stratification on the performance of turbines operating in the Bessaker wind farm. The wind farm is located in a highly complex terrain. Most dominant wind directions recorded ... -
Is more data always better? A simulation study of benefits and limitations of integrated distribution models
(Peer reviewed; Journal article, 2020)Species distribution models are popular and widely applied ecological tools. Recent increases in data availability have led to opportunities and challenges for species distribution modelling. Each data source has different ... -
Is my study system good enough? A case study for identifying maternal effects
(Journal article; Peer reviewed, 2016)In this paper, we demonstrate how simulation studies can be used to answer questions about identifiability and consequences of omitting effects from a model. The methodology is presented through a case study where ... -
Isentropic fluid dynamics in a curved pipe
(Journal article; Peer reviewed, 2016)In this paper we study isentropic flow in a curved pipe. We focus on the consequences of the geometry of the pipe on the dynamics of the flow. More precisely, we present the solution of the general Cauchy problem for ... -
Isogeny Based Cryptography
(Master thesis, 2019)Vi undersøker hvor brukbart tre forskjellige kryposystem er in en post-kvantum verden. Rostovtsev-Stolbunov offentlig nøkkel protokollen, som bruker isogenyer mellom elliptiske kurver, viser seg å være usikre mot ... -
Isogeometric Analysis and Degenerated Mappings
(Master thesis, 2011)In this thesis we have given an introduction to isogeometric finite element analysis on linear elasticity problems in 2D using non uniform rational B-splines (NURBS) as basis functions. We have studied the theory of B-splines ... -
Isogeometric Analysis Based Shape Optimization.
(Master thesis, 2015)We solve shape optimization problems involving partial differential equations. The latter are discretized and solved using isogeometric analysis. B-splines and non uniform rational B-splines are introduced, along with both ... -
Isogeometric analysis of acoustic scattering
(Master thesis, 2015)Acoustic scattering has been thoroughly analyzed with the use of finite element analysis (FEA). The problem at hand is a coupled fluid-structure interaction problem on an unbounded domain, where an object of elastic material ...
