Investigation of high-strength steel component subjected to stretch-bending: effect of forming history
(Journal article; Peer reviewed, 2014)The behaviour of a closed top-hat section made of Dogal 800 DP subjected to stretch-bending is studied both experimentally and numerically. The top-hat section was made by forming of a sheet using a FlexformTM fluid cell ... -
Investigation of Higher-Harmonic Wave Forces and Ringing Using CFD Simulations
(Chapter, 2018)Typical offshore structures are designed as tension-leg platforms or gravity based structures with cylindrical substructures. The interaction of waves with the vertical cylinders in high sea states can result in a resonant ... -
investigation of hybrid power plant configurations for an offshore vessel with co-simulation approach
(Peer reviewed; Journal article, 2023)This work presents a full-system simulator consisting of a generic power system integrated with a vessel model and real-time capabilities. The whole system simulation facilitates evaluating the overall system performance ... -
Investigation of hydrogen embrittlement behavior in X65 pipeline steel under different hydrogen charging conditions
(Journal article; Peer reviewed, 2022)The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ hydrogen charging conditions. The fractured samples were characterized and compared using a combination of scanning ... -
Investigation of individual strategies in the aerial phase in ski jumping
(Peer reviewed; Journal article, 2023)The purpose of this investigation was to examine the performance strategy of three ski jumpers during the steady glide phase and explain how different strategical solutions can lead to jumps of roughly the same length. In ... -
Investigation of influence of pre-treatment and low-temperature on drying kinetics, sorption properties, shrinkage and color of brown seaweeds (Saccharina Latissima)
(Chapter, 2018)Drying kinetics of Saccharina latissima (raw and blanched) at low temperatures (10.0, 25.0 and 38.0 °C) was studied. The effective moisture diffusivity coefficient varied due to temperature alterations in the range between ... -
Investigation of inhomogeneous wave conditions in Sulafjorden
(Chapter, 2021)Complex fjord topography (bathymetry and coastline) may differentiate significantly wave conditions not only compared with the offshore ones but in the vicinity of few tens of meters. In the present work, possible ... -
Investigation of leaching in steel fiber-reinforced shotcrete exposed to fresh and saline groundwater in a subsea road tunnel
(Peer reviewed; Journal article, 2022)The field and laboratory investigations performed in the Frøya subsea road tunnel, constructed between 1998 and 2000, focus on the degree of leaching undergone by steel fiber-reinforced shotcrete in fresh and saline ... -
Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
(Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
Investigation of magnetic field and radial force harmonics in a hydrogenerator connected to a three-level NPC converter
(Chapter, 2017)This paper investigates spatial and time harmonics of flux density and radial force distributions in the airgap of a hydrogenerator with fractional-slot windings. Hydrogenerator is connected to a neutral-point-clamped (NPC) ... -
Investigation of metal dusting corrosion process over UNS N08800 alloy
(Journal article; Peer reviewed, 2017)Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ... -
An Investigation of Models for Under-Reporting in the Analysis of Violence Against Women in Italy
(Journal article; Peer reviewed, 2023)Violence against women is still one of the most widespread and persistent violations of human rights. Despite this, a significant gap of comprehensive, reliable and up-to-date figures on such a largely uncovered phenomenon ... -
Investigation of moonpools as pitch motion reducing device
(Peer reviewed; Journal article, 2021)Moonpools as a device for reducing pitch motion is investigated experimentally, numerically and by an approximate theory. A two-dimensional study is carried out of a rectangular body with two moonpools. Forced heave and ... -
Investigation of non-equilibrium effects during the depressurization of carbon dioxide
(Chapter, 2022)Predicting the phase change of liquid CO2 during depressurization is highly relevant for the application in refrigeration units and for safety analysis in the context of CO2 capture and storage (CCS). For abrupt depressurization ... -
Investigation of Open-Loop Predictor Implementation Methods for Online Parameter Estimation of IPMSM
(Chapter, 2022)Due to the sensitivity to parametric errors, open-loop current predictor-based estimators offer good online tracking of electric machine parameters, however at the price of rotor-speed dependent predictor pole-trajectories, ... -
Investigation of Parametric Resonance in Roll for Container Carrier Ships
