The issue of impulsive synchronization of a class of chaotic systems is investigated. Based on the impulsive theory and linear matrix inequality technique, some less conservative and easily verified criteria for impulsive synchronization of chaotic systems are derived. The proposed method is applied to the original Chua oscillators, and the corresponding synchronization conditions are obtained....

This paper develops a general approach for constructing a response system to implement linear generalized synchronization (GS) with the drive continuous-time chaotic system. Some sufficient conditions of global asymptotic linear GS between the drive and response continuous-time chaotic systems are attained from rigorously modern control theory. Finally, we take Chua s circuit as an example for ...

For modeling nonlinear systems we present a new type of Cellular Neural Networks (CNN) with nonlinear weight and output functions defined by tabulated functions. Training algorithms are used to adjust the behaviour of CNN solutions to those of a system represented only by it ́s output values. A few output values of the system reveal to be sufficient to determine the parameters of the CNN. The pr...

Synchronization in chaotic systems has particular interest in the past few years; it has many applications, especially in secure communications (Carroll & Pecora, 1991; Chua et al, 1992; Ogorzalek, 1993; Chen, 1997; Bai & Lonngren, 1997). Fujisaka and Yamada noticed that ‘by coupling together oscillators which on their own evolved chaotically, it was possible under certain circumstances to forc...

Due to the encouraging increase in their applications, control theory [Lefschetz, 1965] and [Narendra et al., 1973], design of electric circuits [Chua et al., 1990], neurobiology [FitzHugh, 1961] and [Nagumo et al., 1962] piecewise linear differential systems were studied early from the point of view of qualitative theory of ordinary differential equations [Andronov et al., 1966]. Nowadays, a l...

Introduction: Diarrheagenic Escherichia coli (DEC) including enteropathogenic (EPEC), enteroaggregative (EAEC), enterotoxigenic (ETEC), and shiga toxin producing E. coli are among the most common agents of diarrhea. There are various classes of iron uptake receptors, but there is not much data on the presence of these iron receptors in DEC isolates. The present study aimed to evaluate the prese...
