Previously a novel chaos M-ary digital communication method based on spatiotemporal chaos Hamilton oscillator has been proposed. Without chaos synchronization circumstance, It has performance improvement in bandwidth efficiency, transmission efficiency and anti-whitenoise performance compared with traditional communication method. In this paper, the formula for the design of the boundary of zon...

In this part of the paper, the theory of nonlinear dynamics of flexible Euler–Bernoulli beams (the kinematic model of the first-order approximation) under transverse harmonic load and colored noise has been proposed. It has been shown that the introduced concept of phase transition allows for further generalization of the problem. The concept has been extended to a so-called noise-induced trans...

Using a stochastic differential equation (SDE) approach, we examine the dynamics of the continental-scale water balance in the central United States. Whitenoise and colored-noise versions of the model are developed based on analysis of atmospheric data from the National Center for Environmental Prediction (NCEP) reanalysis project and long-term records of precipitation and soil moisture. Improv...

In recent years, the MUSIC timing estimator were proposed for direct-sequence code-division multiple access (DS-CDMA) signals. It has been generally assumed that the channel noise is temporally white. However it may be invalid in practice due to, for instance, the presence of some narrowband interference or the lumping of secondary users into with the noise. In this paper, we consider blind cod...

The colored ~Ornstein-Uhlenbeck! noise-driven nonequilibrium dynamics of massive damped Brownian particles in a periodic but asymmetric potential ~ratchet! is investigated. Our special focus is on the influence of inertia in the particle dynamics for the noise induced, directed current. By means of two approximation schemes ~a unified colored noise approximation and a path-integral approach! an...

This paper is devoted to problem of face localization in color images, more particularly, to the task of grouping pixels with high skin probability to form possible face candidate regions. Using connected components analysis for pixels grouping has a significant drawback, for the noise of skin color detection and non-face skin-colored objects can form connected regions of skin pixels with vivid...
