A Prototype of Ship Routing Decision Support System for an Operational Oceanographic Service [PDF]
TransNav, 2013 A prototype for an operational ship routing Decision Support System using time-dependent meteo-oceanographic fields is presented. The control variable is ship course, which is modified using a directional resolution of less than 27 degrees.

Parametric roll resonance monitoring using signal-based detection [PDF]
Ocean Engineering, 2015 Extreme roll motion of ships can be caused by several phenomena, one of which is parametric roll resonance. Several incidents occurred unexpectedly around the millennium and caused vast fiscal losses on large container vessels. The phenomenon is now well understood and some consider parametric roll a curiosity, others have concerns.

Dynamic Characteristics of Cylinder Push in Bearing Cylindrical Ｒoller Detection System
Journal of Harbin University of Science and Technology, 2021 Aiming at the problem that there is no dynamic analysis of the roller pushing process during the measurement of cylindrical roller dimensions，the model of the cylindrical roller push process is established based on the working principle of the ...

Are Kaluza-Klein modes enhanced by parametric resonance? [PDF]
, 2000 We study parametric amplification of Kaluza-Klein (KK) modes in a higher $D$-dimensional generalized Kaluza-Klein theory, which was originally considered by Mukohyama in the narrow resonance case.

Dynamical Models of Extreme Rolling of Vessels in Head Waves [PDF]
, 2009 Rolling of a ship is a swinging motion around its length axis. In particular vessels transporting containers may show large amplitude roll when sailing in seas with large head waves.

Preheating in Supersymmetric Hybrid Inflation [PDF]
, 1999 We study preheating in a general class of supersymmetric hybrid inflation model. Supersymmetry leads to only one coupling constant in the potential and thus only one natural frequency of oscillation for the homogeneous fields, whose classical evolution ...
