Effect of turbulence intensity on the performance of an offshore vertical axis wind turbine
(Journal article; Peer reviewed, 2015)Offshore wind energy is one of the most competitive renewable energy resources available to us, which until now been under- exploited. Most of the problems associated with wind farm installation like land acquisition, low ... -
Effectiveness of hypnosis in third molar extraction: A randomized controlled trial (HypMol)
(Journal article; Peer reviewed, 2022) -
Effects of density, species interactions, and environmental stochasticity on the dynamics of British bird communities
(Journal article; Peer reviewed, 2022)Our knowledge of the factors affecting species abundances is mainly based on time-series analyses of a few well-studied species at single or few localities, but we know little about whether results from such analyses can ... -
Effects of storage and heat treatment on metabolism and quality of fresh tomato and potato
(Master thesis, 2014)Potato and tomato are two highly consumed vegetables in Norway as well as throughout the rest of the world, with high consumer demands of sensory and nutritional quality. In addition to being sold fresh, a large use for ... -
Effektiv nivådeling: En case-analyse av nivådelingstiltaket på Lykke Li videregående skole
(Master thesis, 2012)Fokuset i denne oppgaven har vært på elevenes opplevelse av å være i en nivådelt klasse, og hvilke momenter ved dette de føler er viktige. Målet er å få en dypere innsikt i hvordan nivådeling kan gjennomføres, og hva som ... -
Efficiency of Screening Designs with a Small Number of Runs
(Master thesis, 2010)Abstract: Two level non-regular designs are widely used in industrial experimentation for factor screening. At the initial stage of experimentation, it is not possible to know in advance which factors are active so it is ... -
An efficient adaptive MCMC algorithm for Pseudo-Bayesian quantum tomography
(Peer reviewed; Journal article, 2022)We revisit the Pseudo-Bayesian approach to the problem of estimating density matrix in quantum state tomography in this paper. Pseudo-Bayesian inference has been shown to offer a powerful paradigm for quantum tomography ... -
Efficient Calculation of Optimal Decisions in Graphical Models
(Master thesis, 2012)We present a method for finding the optimal decision on Random Variables in a graphical model. Upper and lower bounds on the exact value for each decision are used to reduce the complexity of the algorithm, while we still ... -
Efficient coding of natural scenes improves neural system identification
(Peer reviewed; Journal article, 2023)Neural system identification aims at learning the response function of neurons to arbitrary stimuli using experimentally recorded data, but typically does not leverage normative principles such as efficient coding of natural ... -
Efficient Forecasting of Drift Trajectories using Simplified Ocean Models and Nonlinear Data Assimilation on GPUs
(Doctoral theses at NTNU;2020:154, Doctoral thesis, 2020)This thesis presents research on efficient, massively parallel methods and algorithms related to short-term forecasting of drift trajectories in the ocean. The topic has clear societal applications and is an important ... -
Efficient high-dimensional modelling of temperature and extreme precipitation
(Doctoral theses at NTNU;2023:379, Doctoral thesis, 2023) -
Efficient Methods for Topology Optimisation of Fluid flow
(Master thesis, 2018)We consider topology optimisation of two-dimensional Stokes flow. The objective is to distribute a certain amount of solid material in a given domain, such that the total power dissipation is minimised. A generalised Stokes ... -
Efficient Mixing of Arbitrary Ballots with Everlasting Privacy: How to Verifiably Mix the PPATC Scheme
(Peer reviewed; Journal article, 2021)The long term privacy of voting systems is of increasing concern as quantum computers come closer to reality. Everlasting privacy schemes offer the best way to manage these risks at present. While homomorphic tallying ... -
Efficient reordered nonlinear Gauss–Seidel solvers with higher order for black-oil models
(Journal article; Peer reviewed, 2019)The fully implicit method is the most commonly used approach to solve black-oil problems in reservoir simulation. The method requires repeated linearization of large nonlinear systems and produces ill-conditioned linear ... -
Efficient Solvers for Field-Scale Simulation of Flow and Transport in Porous Media
(Doctoral theses at NTNU;2019:374, Doctoral thesis, 2019)The first part of the thesis serves as an introduction to modelling of flow and transport in porous media from the perspective of reservoir simulation. We discuss generation of computational grids and discretization ... -
Efficient spatial designs using Hausdorff distances and Bayesian optimization
(Peer reviewed; Journal article, 2021)An iterative Bayesian optimization technique is presented to find spatial designs of data that carry much information. We use the decision theoretic notion of value of information as the design criterion. Gaussian process ... -
Efficient split-step schemes for fluid–structure interaction involving incompressible generalised Newtonian flows
(Peer reviewed; Journal article, 2022)Blood flow, dam or ship construction and numerous other problems in biomedical and general engineering involve incompressible flows interacting with elastic structures. Such interactions heavily influence the deformation ... -
Eight Times Four Bialgebras of Hypergraphs, Cointeractions, and Chromatic Polynomials
(Journal article; Peer reviewed, 2024)The bialgebra of hypergraphs, a generalization of W. Schmitt’s Hopf algebra of graphs [25], is shown to have a cointeracting bialgebra structure, giving a double bialgebra in the sense of L. Foissy, who has recently proven ... -
