Investigation of Development of the Earth Pressure Coefficient at Rest in Clay During Creep in the Framework of Hyper-Viscoplasticity
(Peer reviewed; Journal article, 2021)The in situ earth pressure coefficient at rest (K0) for clay has been widely discussed in the literature. In engineering practice, the empirical relationships between K0, the overconsolidation ratio (OCR), and the normally ... -
Investigation of drivetrain losses of a DP vessel
(Chapter; Peer reviewed, 2017)Traditionally the efficiency of the drivetrain of a marine vessel is evaluated at rated power and speed. However, the thrust and power consumption of the thrusters are low during DP operation. In this study, the loss energy ... -
Investigation of droplets impinging on a deep pool: transition from coalescence to jetting
(Journal article; Peer reviewed, 2011)An experimental investigation of droplets impinging vertically on a deep liquid pool of the same fluid was conducted. Coalescence and jetting as two of the main regimes were identified and studied. Five fluids, distilled ... -
Investigation of dynamic wind loads on a long-span suspension bridge identified from measured acceleration data
(Journal article; Peer reviewed, 2020)The traditional wind load assessment for long-span bridges relies on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduce some uncertainties. Recent studies have ... -
Investigation of factors affecting the stability of compounds formed by isovalent substitution in layered oxychalcogenides, leading to identification of Ba3Sc2O5Cu2Se2, Ba3Y2O5Cu2S2, Ba3Sc2O5Ag2Se2 and Ba3In2O5Ag2Se2
(Peer reviewed; Journal article, 2022)Four novel compositions containing chalcogenide layers, adopting the Ba3M2O5M02Ch2 layered structure have been identified: Ba3Sc2O5Cu2Se2, Ba3Y2O5Cu2S2, Ba3Sc2O5Ag2Se2 and Ba3In2O5Ag2Se2. A comprehensive comparison of ... -
Investigation of Focusing Wave Properties in a Numerical Wave Tank with a Fully Nonlinear Potential Flow Model
(Journal article; Peer reviewed, 2019)Nonlinear wave interactions and superpositions among the different wave components and wave groups in a random sea sometimes produce rogue waves with extremely large wave heights that appear unexpectedly. A good understanding ... -
Investigation of Free Surface Turbulence Damping in RANS Simulations for Complex Free Surface Flows
(Journal article; Peer reviewed, 2019)The modelling of complex free surface flows over weirs and in the vicinity of bridge piers is presented in a numerical model emulating open channel flow based on the Reynolds Averaged Navier-Stokes (RANS) equations. The ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Journal article; Peer reviewed, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
Investigation of Heck coupling on 6-bromo[2,3-d]thienopyrimidines for construction of new EGFR inhibitor lead structures
