CFD Simulation on Workability of a Seaweed Harvesting Boat Due to Wake-Wash
Journal of Marine Science and Engineering, 2020 In the present study, a 2-ton class seaweed harvesting boat was optimized by employing a W-shape hull form to reduce roll motion due to wake-wash from passing boats.

Enigmatic surface rolls of the Ellesmere Ice Shelf
Journal of Glaciology, 2022 The once-contiguous Ellesmere Ice Shelf, first reported in writing by European explorers in 1876, and now almost completely disintegrated, has rolling, wave-like surface topography, the origin of which we investigate using a viscous buckling instability ...

Modulation of internal estimates of gravity during and after prolonged roll-tilts. [PDF]
PLoS ONE, 2013 Perceived direction of gravity, as assessed by the subjective visual vertical (SVV), shows roll-angle dependent errors that drift over time and a bias upon return to upright.

Nonlinear roll damping of a barge with and without liquid cargo in spherical tanks
Journal of Ocean Engineering and Science, 2016 Damping plays a significant role on the maximum amplitude of a vessel's roll motion, in particular near the resonant frequency. It is a common practice to predict roll damping using a linear radiation–diffraction code and add that to a linearized viscous

Mechanistic driving force for martensite decay in rolling contact fatigue
Tribology International, 2023 Martensite decay due to large scale microstructural alterations is the main fatigue process which occurs during extensive rolling contact fatigue in bearing applications. Despite its practical and scientific importance, the full description of the controlling phenomena is still incomplete.
