Fast divergence-conforming reduced basis methods for stationary and transient flow problems
(Peer reviewed; Journal article, 2020)Reduced basis methods (RB methods or RBMs) form one of the most promising techniques to deliver numerical solutions of parametrized PDEs in real-time with reasonable accuracy [1]. For the Navier-Stokes equation, RBMs based ... -
Fast divergence-conforming reduced basis methods for steady Navier–Stokes flow
(Journal article; Peer reviewed, 2018)Reduced-basis methods (RB methods or RBMs) form one of the most promising techniques to deliver numerical solutions of parametrized PDEs in real-time with reasonable accuracy. For incompressible flow problems, RBMs based ... -
Fast Economic Model Predictive Control for a Gas Lifted Well Network
(Journal article; Peer reviewed, 2018)This paper considers the optimal operation of an oil and gas production network by formulating it as an economic nonlinear model predictive control (NMPC) problem. Solving the associated nonlinear program (NLP) can be ... -
Fast estimation of pressure propagation on general grids
(Master thesis, 2015)To optimize reservoir recovery, estimating drainage volume for different well scenarios to find optimal well locations, is crucial. Knowing the pressure propagation for different well scenarios we can use this to estimate ... -
Fast food increases postprandial cardiac workload in type 2 diabetes independent of pre-exercise: A pilot study
(Journal article; Peer reviewed, 2015)Background Type 2 diabetes aggravates the postprandial metabolic effects of food, which increase cardiovascular risk. We investigated the acute effects of fast food on postprandial left ventricular (LV) function and the ... -
Fast forward to the past? Popular-song-translation communities as spaces for language acquisition and learning.
(Journal article; Peer reviewed, 2017)This paper takes as its point of departure previous decades’ marginalization of translation as a component in formal language teaching and learning, looking at various ways in which information technology provides the means ... -
Fast Frequency Hopping
(Master thesis, 2021)Et raskt frekvenshoppende system med flerveis kanaler innenfor hvert hop er studert og simulert. På grunn av flerveis propagasjon, oppstår forstyrrelser på mottakeren. Dette er fordi symbolene som tas imot er blir blandet ... -
Fast hydrothermal liquefaction of biomass-Development of a plug-flow reactor
(Master thesis, 2017)Hydrothermal liquefaction is a promising technology for converting plant biomass directly to liquid with better fuel properties compared to traditional fast pyrolysis. The technology employs water, in subcritical conditions ... -
Fast hydrothermal liquefaction of native and torrefied wood
(Journal article; Peer reviewed, 2017)The work presented in this paper aimed to examine the effect of heating rate on the bio-crude yield of wood hydrothermal liquefaction. Three different heating methods were developed, resulting in heating rates ranging from ... -
Fast hyperbaric decompression after heliox saturation altered the brain proteome in rats
(Journal article; Peer reviewed, 2017)Better understanding of the physiological mechanisms and neurological symptoms involved in the development of decompression sickness could contribute to improvements of diving procedures. The main objective of the present ... -
Fast Implementation of Two Hash Algorithms on nVidia CUDA GPU
(Master thesis, 2009)User needs increases as time passes. We started with computers like the size of a room where the perforated plaques did the same function as the current machine code object does and at present we are at a point where the ... -
Fast Non-Rigid Registration Using Polynomial Expansion with Diffeomorphic Constraints Applied to Cardiac Ultrasound Volumes
(Master thesis, 2017)This thesis attempted to develop a fast, non-rigid, diffeomorphic image registration implementation and was written as a continuation of a project that was completed during the fall of 2016 \cite{prosjekt_oppgave} which ... -
Fast onboard detection of ice drift changes under stationkeeping in ice
(Peer reviewed; Journal article, 2022)Early detection of ice drift changes is essential for safe stationkeeping in ice-infested waters. This paper presents a conceptual system allowing onboard detection of ice drift changes in managed and unmanaged ice using ... -
Fast Optical Flow Estimation for End-Effector Stabilization
