Tracking Breather Dynamics in Irregular Sea State Conditions [PDF]
Physical Review Letters, 2016 Breather solutions of the nonlinear Schrödinger equation (NLSE) are known to be considered as backbone models for extreme events in the ocean as well as in Kerr media. These exact determinisitic rogue wave (RW) prototypes on a regular background describe a wide-range of modulation instability configurations.

Track Irregularity Time Series Analysis and Trend Forecasting [PDF]
Discrete Dynamics in Nature and Society, 2012 The combination of linear and nonlinear methods is widely used in the prediction of time series data. This paper analyzes track irregularity time series data by using gray incidence degree models and methods of data transformation, trying to find the connotative relationship between the time series data. In this paper, GM (1,1) is based on first‐order,

Analysis and forecast of track composite irregularity
Procedia Engineering, 2011 AbstractTrack composite irregularity is the source of violent harassment of the wheel-rail system. They cause a vibration, and the track irregularity has the significant impact on train's driving security, stability, the life of track component and the vehicles as well as the environmental noise.
