The Smart Detection of Ship Severe Roll Motions and Decision-Making for Evasive Actions

open access: yesJournal of Marine Science and Engineering, 2020
This paper presents a numerical model for the smart detection of synchronous and parametric roll resonance of a ship. The model implements manoeuvring equations superimposed onto ship dynamics in waves.

A Numerical Application of Ship Parametric Roll under Second Generation Stability Criteria [PDF]

open access: yesJournal of Eta Maritime Science, 2019
In this study, the parametric roll motion for the benchmark container ship form C11 is investigated by using the second generation stability criteria, which were intensively studied by IMO (International Maritime Organization).

Multi-level approach for parametric roll analysis

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2011
The present study considers multi-level approach for the analysis of parametric roll phenomena. Three kinds of computation method, GM variation, impulse response function (IRF), and Rankine panel method, are applied for the multi-level approach.

Parametric rolling in regular head waves of the Kriso container ship : numerical and experimental investigation in shallow water [PDF]

open access: yes, 2019
The IMO Intact Stability Code considers the parametric rolling phenomenon as one of the stability failure modes because of the larger roll angles attained.

High-Reynolds shallow flow over an inclined sinusoidal bottom [PDF]

open access: yes, 2010
An experimental study of a turbulent free-surface shallow flow over an inclined sinusoidal bottom with a fixed corrugation amplitude is presented. A parametric analysis is performed by varying both the inclination angle and the Reynolds number.

Parametric resonance of fractional viscoelastic webs under time-dependent tension

open access: yesResults in Physics, 2023
The focus of this paper is on the parametric resonance of fractional viscoelastic webs under time-dependent tension. The novelty of this work lies in the introduction of a fractional order model for viscoelastic webs and the time-dependent tension in ...

The Possibility of Inflation in Asymptotically Safe Gravity [PDF]

open access: yes, 2012
We examine the inflationary modes in the cubic curvature theories in the context of asymptotically safe gravity. On the phase space of the Hubble parameter, there exists a critical point which corresponds to the slow-roll inflation in Einstein frame ...
