A bstract. T he periodic behavior of a particu lar class of dynamical sys tems , the cellular automata (CA) , is studied . A lar ge class of CAs is defined , (containing both addit ive and nonadditive CAs) in terms of the sensi tivity of t he local rule on which the CA is based . For this class , the set of configurations which ente r a cycle afte r a finit e number of it erat ions is complete ...

They are finding an increasing number and variety of applications not only in pure research, but in medicine and heal th, in many industries such as mining, text i les , metallurgy and the oil industry, a...

Network Quality of Service (QoS) criteria of interest include conventional metrics such as throughput, delay, loss, and jitter, as well as new QoS criteria based on power utilization, reliability and security. In this paper we suggest a theoretical framework for the characterization and comparison of adaptive routing algorithms which use QoS as the criterion to select between different paths th...
