Syklisters premisser for valg av rute - En studie av forklaringsfaktorer som påvirker syklisters rutevalg til bruk i en rutevalgsmodell
(Master thesis, 2018)De norske byene benytter transportanalyser for å undersøke potensielle forbedringsområder som skal bidra til å nå nullvekstmålet for persontransport med bil. Transportmodellene som benyttes i dag egner seg dårlig til å ... -
Symmetry breaking modelling for azimuthal combustion dynamics
(Peer reviewed; Journal article, 2020)Annular combustors can exhibit azimuthal thermoacoustic instabilities, which can rotate as a spinning wave at the speed of sound in the azimuthal direction, oscillate as a standing wave with pressure nodes fixed in space, ... -
Symmetry-breaking in thermoacoustics: Theory and experimental validation on an annular system with electroacoustic feedback
(Peer reviewed; Journal article, 2023)In this study, we investigate experimentally the linear and nonlinear thermoacoustic response of an annular combustor model with electroacoustic feedback to study the effects that various types of asymmetric modifications ... -
Symptoms of anxiety and depression and risk of atrial fibrillation-the HUNT study
(Peer reviewed; Journal article, 2019)Background Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Anxiety and depression may activate the autonomic nervous system which is likely to play an important role in the etiology of AF. However, ... -
Synchronization of networked oscillators under nonlinear integral coupling
(Journal article; Peer reviewed, 2018)In this paper, we consider synchronization of dynamical systems interconnected via nonlinear integral coupling. Integral coupling allows one to achieve synchronization with lower interaction levels (coupling gains) than ... -
Synchrotron X-ray micro-computed tomography imaging of 3D re-entrant micro lattice during in situ micro compression experimental process
(Peer reviewed; Journal article, 2020)3D re-entrant mechanical metamaterials were designed and fabricated with PμLSE (Projection Micro Litho Stereo Exposure) 3D printing technique, synchrotron X-Ray tomography 3D imaging and in situ mechanical experiments were ... -
Synconn_build: A python based synthetic dataset generator for testing and validating control-oriented neural networks for building dynamics prediction
(Peer reviewed; Journal article, 2023)Applying model-based predictive control in buildings requires a control-oriented model capable of learning how various control actions influence building dynamics, such as indoor air temperature and energy use. However, ... -
Synergies in Heat, Power and Hydrogen by Integrating a Power Plant and an Oil Refinery
(Master thesis, 2007)The refineries need for hydrogen in hydrotreatment is increasing due to stricter environmental legislation and changes in product demand. At the same time the production of hydrogen in the reformers within the refineries ... -
Synergistic control barrier functions with application to obstacle avoidance for nonholonomic vehicles
(Chapter, 2021)Control barrier functions (CBFs) have recently emerged as a means to ensure safety of controlled dynamical systems. CBFs are suitable for obstacle avoidance, where the CBF is often constructed from the distance and relative ... -
Synkinematic intrusion of granitoid sheets, with implications for molybdenite deposits in the Knaben Zone - Sirdal Magmatic Belt, SW Norway
(Master thesis, 2015)The Knaben Zone represents a N-S-elongated zone with abundant xenolith screens and molybdenite deposits within the late Mesoproterozoic Sirdal Magmatic Belt (SMB) batholith in the Sveconorwegian orogen, in SW Norway. The ... -
Synliggjøreing av potensialet for merverdi ved bruk av BIM
(Master thesis, 2021)I dag står bygg- og anleggsbransjen ovenfor et stort digitalt skifte. Målet er å gjøre bransjen mer bærekraftig og miljøvennlig, uten at dette går på bekostning av kvalitet, tid og økonomi. Digitaliseringen som bransjen ... -
A synoptic history of the development, production and environmental oversight of hydropower in Brazil, Canada, and Norway
(Peer reviewed; Journal article, 2021)Sustainable global energy production is back-stopped by hydropower which is responsible for a significant share of the green energy produced worldwide. Hydropower, however, does not come without some environmental impacts ... -
Syntactic Foam as Mitigation against Thermally Induced Trapped Annulus Pressures on the Linnorm field
