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
(Chapter; Peer reviewed, 2015)Parametric roll resonance is of concern for container and fishing vessels, especially in head-sea waves. Here this phenomenon is investigated with a numerical method based on potential-flow theory with viscous corrections ... -
Investigation of Partial Discharges in AlN Substrates under Fast Transient Voltages
(Peer reviewed; Journal article, 2022)The objective of this paper is to characterize partial discharge (PD) inception voltages and patterns at sinusoidal and square voltages in insulating ceramic substrates with generic manufacturing defects. PD tests were ... -
Investigation of Permanent Deformation Behavior of Steel Slag Asphalt Mixture under Indoor Simulation
(Peer reviewed; Journal article, 2021)Previous studies have indicated that steel slag can be used as a substitute for natural aggregates in asphalt mixture, while little attention has been paid to systematic investigation of the influences of various external ... -
Investigation of pinholes in Czochralski silicon ingots in relation to structure loss
(Journal article; Peer reviewed, 2019)In the production of monocrystalline silicon by the Czochralski process, structure loss frequently reduces yield and increases production time. Structure loss means the transition from monocrystalline to multicrystalline ... -
Investigation of punctuality of local trains - the case of Oslo area
(Journal article; Peer reviewed, 2017)Norwegian railways experienced a steady decline in punctuality during the period 2007-2010. This paper briefly discusses the concept of train punctuality, influencing factors on punctuality, and investigates relationship ... -
Investigation of sediment erosion phenomenon for different blade angle distribution in Francis runner
(Peer reviewed; Journal article, 2021)Wear and tear of hydraulic turbine due to sediment erosion is one of the major problems in hydropower plants located in the Himalayan and Andes regions. High sediment concentration in water of such areas wears down the ... -
Investigation of slag and condensate from the charge top in a FeSi75 furnace
(Chapter, 2023)Metallurgical silicon/ferrosilicon is produced industrially in submerged arc furnaces by carbothermic reduction of quartz. In addition to raw materials, oxide impurities are present in the furnace. Accumulated slag is ... -
Investigation of Sodium Sulfate Additions into Cryolite-Alumina Melts
(Journal article, 2016)In the Hall-Héroult process, sulfur impurities may not only emit harmful gases but also reduce current efficiency. To better understand this process, the behaviour of sulfur compounds in a cryolite-alumina melt at 1253 K ... -
Investigation of Solar Photovoltaic-Thermal (PVT) and Solar Photovoltaic (PV) Performance: A Case Study in Ghana
(Peer reviewed; Journal article, 2020)The main objective of this paper is to experimentally assess the real-life outdoor performance of a photovoltaic-thermal (PVT) module against a conventional photovoltaic (PV) system in a hot humid tropical climate in Ghana. ... -
Investigation of Spent Refractory Lining in an Anode Baking Furnace
(Journal article; Peer reviewed, 2017)The refractory lining in anode baking furnaces is exposed to harsh chemical environment and thermal cycling. Spent refractory lining from an anode baking furnace after 4000 days in operation was investigated. Variation in ... -
Investigation of Spin Coating Cerium-Doped Hydroxyapatite Thin Films with Antifungal Properties
(Peer reviewed; Journal article, 2021)In this study, the cerium-doped hydroxyapatite (Ca10−xCex(PO4)6(OH)2 with xCe = 0.1, 10Ce-HAp) coatings obtained by the spin coating method were presented for the first time. The stability of the 10Ce-HAp suspension particles ... -
An investigation of the anisotropic properties of heat-treated maraging steel grade 300 processed by laser powder bed fusion
(Peer reviewed; Journal article, 2021)In order to explore the possibilities enabled by laser beam powder bed fusion of metals (PBF-LB/M), reliable material models are necessary to optimize designs with respect to weight and stiffness. Due to the unique processing ... -
Investigation of the change in soil fabric during cone penetration in silt using 2D measurements
(Journal article; Peer reviewed, 2017)Interpretation of CPTU testing in silt is non-trivial because of the partially drained conditions that are likely to occur during penetration. A better understanding of the pore pressure generation/dissipation is needed ... -
