... ABSTRACT Due to casualties and property losses in ship capsizing accidents, the study of ship capsizing is of great significance. In this study, two kinds of filter models are used to filter the white noise load to obtain colored noises with the statistical characteristics of the actual wave...

... method, but EMD method can cause modal aliasing in time-frequency analysis. In this paper, the ensemble empirical mode decomposition (EEMD) method is used to solve this problem. Combined with auxiliary noise analysis method, white noise with uniform spectrum distribution is added to the analysis signal...

... plus different realizations of finite variance white noise. Let x be the signal of interest. The EEMD algorithm can be described as follows (Wu & Huang, 2009): Step 1. Generate x(i) = x + w(i), where w(i) (i=1I) is a zero mean unit variance white noise realization, and > 0. Step 2. Decompose completely...

... integral method by the linear system theory. In the later method, the kernel function and a white noise usually are used. where, 7J(t) = L: h( r)n(t - ddT (1) (2) We have succeeded to obtain the kernel function analytically, namely impulse response function, in the time domain of Pierson- Moskowitz (P-M...

... with nonlinear restoring as well as nonlinear damping In the field of random vibration of the stochastic analysis has been concentrated on the calculation of response to white noise. However, in the real ocean, the excitation can not be modeled as white noise. To treat the non-white noise input Dunne(1982) has...

... pseudo white noise as described by Linfoot et al 1 . System Description The wave basin is 9m × 9m × 0.9m (deep) and is equipped with 18 independent bottom-hinged "absorbing" wavemakers positioned along one side of the basin. Beaches on the remaining three sides absorb waves and thus reduce phase...
