RailCheck: A WSN-Based System for Condition Monitoring of Railway Infrastructure
(Chapter, 2018)Contemporary tools used to monitor railway points and crossings are ineffective. Routine inspections of these critical parts are still being performed manually by specially-trained inspectors. This creates higher expenditure ... -
RailCheck: Functional Safety for Wireless Condition Monitoring of Railway Turnouts and Level Crossings
(Chapter, 2019)Increasing demands for more cost-effective, reliable and safer railway infrastructure unavoidably bring up the need for transitioning from current preventive maintenance strategies to more efficient, predictive, condition-based ... -
RAM and Safety Analysis of Railway Signalling Systems
(Master thesis, 2010)Demonstrating compliance with RAM and Safety requirements is a prerequisite before railway application products are qualified for their intended application. EN 50126 requires documented evidence which shows how railway ... -
RAM-analysar for jernbaneinfrastruktur
(Master thesis, 2017)Ved bygging av ny jernbaneinfrastruktur, eller betydeleg endring av eksisterande jernbaneinfrastruktur, skal det gjennomførast RAM-analysar. Slike analysar vurderer jernbaneinfrastrukturen si yting, i form av evna den har ... -
Rammeverk for implementering av additiv tilvirkning i Equinor
(Master thesis, 2019)For å lykkes med implementeringen av additiv tilvirkning i olje og gass-industrien, må det utarbeides en styrings-plattform for den tilhørende arbeidsprosessen. Dette er en omfattende oppgave som involverer flere ulike ... -
RAMS data for railway infrastructure
(Master thesis, 2011)Having an operational database in different industries for different equipment has been a big challenge for decades for all reliability engineers and analysers. Many different databases are introduced in order to help ... -
Random Bin Picking of Low-Texture Planar Industrial Parts Using 3D Machine Vision
(Master thesis, 2019) -
Rapid calculation of residual stresses in dissimilar s355– aa6082 butt welds
(Peer reviewed; Journal article, 2021)An analytical model is proposed to rapidly capture the thermal and residual stresses values induced by the hybrid metal extrusion and bonding (HYB) process on dissimilar-metal butt-welded joints. The power input for two ... -
Rapid extrapolation of high temperature low-cycle fatigue curves for a nickel superalloy
(Journal article; Peer reviewed, 2019)In many industrial applications, ranging from the energy, the aviation to the microelectronics field, metallic alloys are subjected to fatigue load at elevated temperatures. The detrimental influence of temperature and ... -
Rapid prototyping and physical modelling in the development of a new additive manufacturing process for aluminium alloys
(Journal article; Peer reviewed, 2019)In this work, rapid prototyping and physical modelling are used to evaluate four different extruder and deposition concepts for the Hybrid Metal Extrusion & Bonding (HYB) additive manufacturing (AM) process for aluminium ... -
Rapid prototyping tools
(Master thesis, 2016)This paper is the description of the method and result of the master project of Petter Ildgruben at the Department of Engineering Design and Materials (IPM) at the Norwegian University of Science and Technology (NTNU) in ... -
Rapid Strain Energy Density evaluation for V-notches under mode I loading conditions
(Peer reviewed; Journal article, 2020)This work investigates the possibility to evaluate the Strain Energy Density value with a free mesh model suggesting the use of a correcting formula a posteriori. Several numerical analyses were carried out to prove the ... -
RCA og moderne vedlikeholdsstyring

Real-Time Data for Risk Assessment in the Offshore Oil and Gas Industry
(Chapter, 2017)Recent major accidents in the offshore oil and gas (O&G) industry have showed inadequate assessment of system risk and demonstrated the need to improve risk analysis. While direct causes often differ, the failure to update ... -
Real-World fNIRS Brain Activity Measurements during Ashtanga Vinyasa Yoga
(Journal article; Peer reviewed, 2021)Functional near-infrared spectroscopy (fNIRS) is often praised for its portability and robustness towards motion artifacts. While an increasing body of fNIRS research in real-world environments is emerging, most fNIRS ... -
Realiserte gevinster av prestasjonsmåling
(Master thesis, 2019)Statistisk sentralbyrå publiserer jevnlig statistikk over produktiviteten i norsk bygg- anlegg- og eiendomsnæring (BAE) som viser et produktivitetsfall på 10 prosent siden år 2000. Byggekostnadene har økt mer enn generell ... -
