Noise-induced chaos is an interesting phenomenon. However, it is a subtle issue because of the difficulty in distinguishing between true low-dimensional chaos and noise. In this review article, we consider how to define noise-induced chaos and what constitutes a test for noise-induced chaos. The mechanism for noise-induced chaos is studied by considering the long-term growth rate of the logarit...

For two particles in a disordered chain of length L with on-site interaction U , a duality transformation maps the behavior at weak interaction onto the behavior at strong interaction. Around the fixed point of this transformation, the interaction yields a maximum mixing of the one body states. When L ≈ L1 (the one particle localization length), this mixing results in weak chaos accompanied by ...

Chaotic home lives are correlated with behavior problems in children. In the study reported here, we tested whether there was a cross-lagged relation between children's experience of chaos and their disruptive behaviors (conduct problems and hyperactivity-inattention). Using genetically informative models, we then tested for the first time whether the influence of household chaos on disruptive ...

Fraudulent e-mails, known as phishing attacks, have brought chaos across the digital world causing billions of dollars of damage. These attacks are known for their ability to exploit the human aspect of a computer system by pretending to originate from a source trusted by the victim. While technology defenses have been setup for protection, people are still succumbing to these attacks at alarmi...

Despite continued worldwide chaos brought about by challenged economies and global terrorist actions, e-commerce continues to grow in import for all regions of the world. B2B sales were approaching 1US trillion worldwide by year-end. Worldwide holiday sales were expected to double from 2001, with Europe sales overtaking those in the US. B2C sales, while expanding, were challenged and may near 0...

The centrifugal instability leading to Taylor vortex ow can be controlled by harmonic oscillations of the inner cylinder in the axial direction. Over a wide range of frequencies and amplitudes of this oscillation, the dynamics remain axisymmetric and the response to the applied periodic control mechanism is synchronous. We implement an accurate and e cient spectral-projection scheme for solving...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...

Studies of nonlinear dynamical systems with many degrees of freedom show that the behavior of these systems is significantly different as compared with the behavior of systems with less than two degrees of freedom. These findings motivated us to carry out a survey of research focusing on the behavior of high-dimensional chaos, which include onset of chaos, routes to chaos, and the persistence o...

In this study, simultaneous asynchronous oscillatioiis of chaos observed in a simple autononioiis circuit are iiivestigated by both of circuit experiments and coniputer calculations. This circuit consists of two nonlinear subcircuits having different oscillation frequencies coupled by one linear negative resistor. I n the case that oscillation frequencies of two subcircuits are quite direrent, ...

In this study, a simple chaos communication system including modulation-demodulation circuits is studied. The influence of modulation-demodulation circuits to chaos synchronization is investigated. For the estimation of communication quality, bit error rate (BER) is calculated by computer simulation when a sequential random pulse information signal is transmitted via this proposed system. key w...
