Statistical Analysis of Clustering in Globally Coupled Chaotic Circuits

In this study, a globally coupled system of chaotic circuits with small variations in their oscillation frequencies is investigated. In our previous study, by computer simulations, the generation of clustering and chaotic change of the cluster size are confirmed for five and thirty circuits case. Further, we confirmed that phenomenon from experimental results for five circuits case. In order to understand the phenomena correctly, we make detailed investigation on the statistical information of the clustering for thirty circuits case, such as survival time of a certain size of clusters.
