An Open-System Approach for the Characterization of Spatio-Temporal Chaos

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Spatio - Temporal Chaos in a Coupled System of Ring Oscillators

We have investigated a chaotic circuit utilizing CMOS ring oscillators[1]. The circuit consists of two CMOS ring oscillators and two diodes. A CMOS ring oscillator is used for CMOS process performance test. This oscillator consists of a series of inverter circuits. It has a very simple structure. Therefore, we consider that the proposed circuit is realized very easily. In the past studies, we h...

Spatio-temporal Chaos. Errors and Correction

Spatio-temporal chaos in a chemotaxis model

In this paper we explore the dynamics of a one-dimensional Keller–Segel type model for chemotaxis incorporating a logistic cell growth term. We demonstrate the capacity of the model to self-organise into multiple cellular aggregations which, according to position in parameter space, either form a stationary pattern or undergo a sustained spatio-temporal sequence of merging (two aggregations coa...

Spatio-temporal Chaos. 3. Natural Spatio-temporal Measures for Coupled Circle Map Lattices

In a series of three papers, we study the geometrical and statistical structure of a class of coupled map lattices with natural couplings. These are innnite-dimensional analogues of Axiom A systems. Our main result is the existence of a natural spatio-temporal measure which is the spatio-temporal analogue of the SRB measure. In the rst paper we develop a stable manifold theory for such systems ...
