Status på problemer knyttet til bruk av ulike biobrensler
(SINTEF Energi. Rapport;, Research report, 2008)Dagens energibehov øker i en slik takt at bruk av alternative biobrensler i biomasse kraft-varme anlegg i økende grad blir nødvendig for å oppnå kostnadseffektivitet. Disse alternative biobrenslene byr ofte på problemer ... -
Stayin’ alive: The introduction of municipal in-patient acute care units was associated with reduced mortality and fewer hospital readmissions
(Peer reviewed; Journal article, 2023)Background: Integrated care is seen as integral in combating the current and projected resource scarcity in the healthcare systems of developed economies. Previous research finds positive effects from implementing intermediate ... -
Steam Reforming of Methane on Sponge Iron: Influence of GasComposition on Reaction Rate
(Peer reviewed; Journal article, 2020)Direct Reduction processes use gases (CO and H2) for iron reduction and production of sponge iron or direct reduced iron (DRI). The generation of this gas occurs through methane reforming, which can be done in a reformer ... -

A Steerable and Electromagnetically Tracked Catheter: Navigation Performance Compared With Image Fusion in a Swine Model
(Peer reviewed; Journal article, 2022)Purpose: Cannulation of visceral vessels is necessary during fenestrated and branched endovascular aortic repair. In an attempt to reduce the associated radiation and contrast dose, an electromagnetically (EM) trackable ... -
STEM-EDS of Inception Sites of Vented Trees in a HV XLPE Subsea Cable
(Chapter, 2023)High voltage XLPE cable cores have been subjected to wet ageing following the recommendations in CIGRE TB 722. The electrical ageing was performed at 500 Hz and 10 kV/mm. Vented water trees were detected initiating and ... -
Stepwise refinement of sequence diagrams with soft real-time constraints
(Journal article; Peer reviewed, 2015)UML sequence diagrams and similar notations are much used to specify and analyze computer systems and their requirements. Probabilities are often essential, in particular for capturing soft real-time constraints. It is ... -
Stepwise refinement of sequence diagrams with soft real-time requirements
(Research report, 2011)UML sequence diagrams and similar notations are much used to specify computer systems, serving for example as specifications for programmers, or as a means for validating requirements. When specifying and analyzing computer ... -
Stereographic projection for industrial manipulator tasks: Theory and experiments
(Chapter, 2011)In this paper, we present a solution and experimental results for real-time control of manipulation tasks considering the alignment of a robots end effector relative to some reference. The developed controller is applicable ... -
Stereoscopic Images and Virtual Reality techniques in daylighting research: A method-comparison study
(Peer reviewed; Journal article, 2022)Visualization and presentation techniques are experiencing a rapid development and application in the architectural profession and beyond. As such, Stereoscopic Images (SI) and Virtual Reality (VR), both advanced visualization ... -
Stiller byggherrene krav til tilgjengelighet?
(Prosjektrapport (Norges Byggforskningsinstitutt);360, Research report, 2004)Prosjektet handler om byggherrens rolle og betydning når det gjelder ivaretakelse av kravet om brukbarhet for funksjonshemmede i bygninger. Problemstillinger De mest sentrale problemstillingene i forhold til prosjektets ... -
Stimulating relative permeability changes by low-frequency elastic waves: Theory and lab experiments
(Peer reviewed; Journal article, 2022)A model is presented to describe how low-frequency vibrations can induce changes to relative permeabilities in dual-porosity dual-permeability rocks. We show that a combination of two physical processes may cause this ... -
Stimulating release of undersized fish through a square mesh panel in the Basque otter trawl fishery
(Journal article; Peer reviewed, 2019-11-19)Discards of regulated species in the Basque mixed trawl fishery are a challenge. In 2006, a square mesh panel (SMP) was introduced in the fishery to increase the release efficiency of undersized fish. However, studies have ... -
Stochastic and self-consistent 3D modeling of streamer discharge trees with Kinetic Monte Carlo
(Peer reviewed; Journal article, 2024)This paper contains the foundation for a new Particle-In-Cell model for gas discharges, based on Îto diffusion and Kinetic Monte Carlo (KMC). In the new model the electrons are described with a microscopic drift-diffusion ... -
Stochastic DSMC model for large scale dense bubbly flows
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Bubble columns are widely used in the chemical industry because of their simple design and high efficiency. The scale-up of these kinds of columns is challenging and time-consuming. Since high throughput is targeted, they ... -
Stochastic dynamic load effect and fatigue damage analysis of drivetrains in land-based and TLP, spar and semi-submersible floating wind turbines
(Journal article; Peer reviewed, 2015-07)This paper deals with the feasibility of using a 5 MW drivetrain which is designed for a land-based turbine, on floating wind turbines. Four types of floating support structures are investigated: spar, TLP and two ... -
A stochastic dynamic programming model for hydropower scheduling with state-dependent maximum discharge constraints
(Peer reviewed; Journal article, 2022)We present a medium-term hydropower scheduling model that includes inflow- and volume-dependent environmental constraints on maximum discharge. A stochastic dynamic programming algorithm (SDP) is formulated to enable an ... -
Stochastic electricity dispatch: A challenge for market design
(Peer reviewed; Journal article, 2018)We consider an energy-only electricity market where some generation and/or load is uncertain, and where there are flexibility costs, i.e. some conventional power plants have to be scheduled well before real time in order ... -
