Duplex steel welding in arctic conditions – Correlation of welding parameters in relation to HISC
(Master thesis, 2021)The second part of XX century has taken a large part of Oil & Gas production to the offshore. The processes and equipment used inland, had to be adapted and optimized for severe marine and subsea conditions. In order to ... -
Duplex steel welding in artic conditions – Correlation of welding parameters in relation to HISC
(Peer reviewed; Journal article, 2021)Duplex steel is an austenitic-femtic steel alloy commonly used in the offshore and subsea oil and gas industry. Duplex steel provides a unique combination of good mechanical properties and corrosion resistance in sweet and ... -
Duration of elevated heart rate Is an important predictor of exercise-induced troponin elevation
(Peer reviewed; Journal article, 2020)Background The precise mechanisms causing cardiac troponin (cTn) increase after exercise remain to be determined. The aim of this study was to investigate the impact of heart rate (HR) on exercise‐induced cTn increase by ... -
Dybdelæring i matematikk
(Master thesis, 2023)This study examines deep learning in mathematics and investigates whether a focus on deep learning can lead to deep understanding of a mathematical topic. Deep learning proves to be a diverse concept with various interpretations ... -
Dybdelæring og tverrfaglighet
(Master thesis, 2023)Da ny læreplan av 2020 ble introdusert, var det spesielt et begrep som stod i fokus - dybdelæring. Hvor tidligere læreplan ønsket at elevene skulle kunne utføre oppgaver gjennom en instrumentell forståelse, skulle elevene ... -
Dynamic Acceptance Criteria for Periodic Testing of Downhole Safety Valves
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-15)Downhole Safety Valves (DHSVs) are periodically leak tested as part of the preventative maintenance program on an oil and gas producing facility. The last couple of years, the oil and gas industry on the Norwegian Continental ... -
Dynamic Analysis and Extreme Response Evaluation of Lifting Operation of the Offshore Wind Turbine Jacket Foundation Using a Floating Crane Vessel
(Peer reviewed; Journal article, 2022)The jacket is the most widely-used fixed foundation for offshore wind turbines due to its superior strength and low installation cost in relatively deep waters. Floating crane vessels are commonly used to install jacket ... -
