CHAOS, BIFURCATION AND ROBUSTNESS OF A CLASS OF HOPFIELD NEURAL NETWORKS

International Journal of Bifurcation and Chaos, 2011
Chaos, bifurcation and robustness of a new class of Hopfield neural networks are investigated. Numerical simulations show that the simple Hopfield neural networks can display chaotic attractors and limit cycles for different parameters. The Lyapunov exponents are calculated, the bifurcation plot and several important phase portraits are presented as ...

A Novel Chaos Based Robust Watermarking Framework

2016
In this paper, a novel logo watermarking framework is proposed using non-linear chaotic map. The essence of proposed technique is to use chaotic map to generate keys to be used in the embedding process. Therefore, a method for generating keys is first proposed followed by the embedding process. A robust extraction process is then proposed to verify the

ROBUST CONTROL OF SPATIOTEMPORAL CHAOS IN COUPLED MAP LATTICES

International Journal of Bifurcation and Chaos, 2009
In this paper, a new method for controlling spatiotemporal chaos in discrete-time spatially extended systems modeled by coupled map lattices is proposed. This method is based on quasi-sliding mode using a Lyapunov function. This method enables the system to drive the chaotic motion toward any desired trajectory via a sliding surface in the error space.

On the robust chaos synchronization of RCLSJ models

2008 IEEE Conference on Soft Computing in Industrial Applications, 2008
This paper is concerned with the robust chaos synchronization problem for coupled RCL-shunted Josephson junction (RCLSJ) models. The variable structure control (VSC) technique is introduced to propose a nonlinear controller such that the coupled RCLSJ models with different parameters can be synchronized even when the uncertainties are present.

Robust chaos in systems of circular geometry

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
We propose two models of systems that manifest robust chaotic regimes associated with uniformly hyperbolic attractors. The model schemes are rings of oscillators and nonlinear elements arranged in such way that signals undergo special transformation during full rotation along the rings.

A modifid robust adaptive chaos synchronization

2004 International Conference on Signal Processing and Communications, 2004. SPCOM '04., 2005
In this paper, a modified robust adaptive chaos synchronization structure is proposed. To increasing the security of the communication network the parameters of the chaotic transmitter is changed. By changing the parameters of the chaotic transmitter (sender section) the conventional state observer (receiver section) cannot be retrieved the actual ...

Robust chaos in dynamic optimization models

Ricerche Economiche, 1994
Summary: The purpose of this paper is to investigate the (theoretical) importance of chaos as a phenomenon occurring in dynamic optimization problems. The intertemporal models we focus on are specified by a standard aggregative production function, an immediate return function depending on current consumption, capital input and a taste parameter, and a

ON THE OCCURENCE OF ROBUST CHAOS IN A SMOOTH SYSTEM

Modern Physics Letters B, 2001
We investigate the occurrence of robust chaos in a smooth system. We present a general theorem and a practical procedure for constructing S-unimodal maps that generate robust chaos. This result is contrary to the hypothesis that robust chaos cannot exist in smooth systems.
