In this work, the effects of diversity in large arrays of chaotic systems are studied. It is here shown how very regular spatio-temporal patterns are achieved by perturbing a system parameter with a suitable spatial disturbance. Moreover, it is shown that synchronisation and order is better achieved if the variation of the parameter is generated by a chaotic system rather than by a random generator based on a stochastic process with uniform distribution. Our conjecture is then validated by several simulation experiences on long chains of both mechanical (pendula) and electrical (Chua's circuits) systems.

Abstract
In this work, the effects of diversity in large arrays of chaotic systems are studied. It is here shown how very regular spatio-temporal patterns are achieved by perturbing a system parameter with a suitable spatial disturbance. Moreover, it is shown that synchronisation and order is better achieved if the variation of the parameter is generated by a chaotic system rather than by a random generator based on a stochastic process with uniform distribution. Our conjecture is then validated by several simulation experiences on long chains of both mechanical (pendula) and electrical (Chua's circuits) systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
