Since the pioneering work on the use of chaos for communication [Hayes & Grebogi, 1993; Hayes et al., 1993; Hayes et al., 1994] and synchronization [Pecora & Carroll, 1990; Cuomo & Oppenheim, 1993; Perez & Cerdeira, 1995; Short, 1997; Kocarev & Parlitz, 1996; Rosenblum et al., 1996; Zaks et al., 1999], many ideas have been presented to use nonlinear electronic circuits for communication purpose...

Human ventilation at rest exhibits mathematical chaos-like complexity that can be described as long-term unpredictability mediated (in whole or in part) by some low-dimensional nonlinear deterministic process. Although various physiological and pathological situations can affect respiratory complexity, the underlying mechanisms remain incompletely elucidated. If such chaos-like complexity is an...

A circular-sided square microcavity laser etched a central hole has achieved chaos operation with bandwidth of 20.8 GHz without external optical feedback or injection, in which the intensity probability distribution chaotic signal two-peak pattern was observed. Based on self-chaotic microlaser, physical random numbers at 400 Gb/s were generated by extracting four least significant bits other co...

Chaotic systems are widely used in various aspects such as information security, signal processing, and synchronous control. The structural complexity the chaotic behavior of two significant factors affecting their practical applications. In this paper, we propose a universal two-dimensional (2D) absolute-cosine model (ACCM). 2D-ACCM is composed nonlinear bounded cosine function an absolute val...

This paper investigates the utilization of the timecontinuous chaotic system, which is UEDA oscillator, as the chaotic pseudo random number generator. (CPRNG). Repeated simulations were performed investigating the influence of the oscillator sampling time to the selected heuristic, which is differential evolution algorithm (DE). Initial experiments were performed on the selected test function i...

Analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. Thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. This paper compares the performance of chaos theory with Anfis model and discusses ...

By constructing a circuit consisting of a diode, resistor, and inductor in series with sinusoidallydriven function generator, period doubling bifurcation and chaotic behavior were observed in this experiment. By using a fixed frequency close to the value of resonance frequency of the circuit and adjusting the voltage amplitude of the function generator, the circuit exhibited chaotic behavior. A...

To protect image data privacy, a secure and fast encryption algorithm using hyper-chaos based key generator vector operation is proposed. Firstly, we introduce novel post-process method to create matrix for significantly reducing the iterations of hyperchaotic system from W×H/4 2W an size W×H. And within post-process, random selector driven by piecewise linear chaotic map ensures good randomnes...
