Via linear stability analysis method, the stability of the synchronized state of CMN is determined by the eigenvalues of a matrix A, and for the chaos Logistic map, the range of the coupling strength of CMN is given. These results are applied to a class of multi-layer center networks, and some specific results are induced. Finally, numerical simulations are presented to verify these results.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124954875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the permutation of sub-images composing of high 4-bits of the original image has a relatively high computational complexity, in the new scheme the permutation of sub-images is performed with low 4-bits instead, which therefore has a lower computational complexity. Experiment has been carried out, showing relatively high efficiency and security of the new cryptosystem.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125644327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, the evolution of network structure and node attributes in the network is a key issue for us to understand the network properties and to design appropriate internetworking technology. In this paper, we define “favorability degree” to quantity the attributes of a node in the network. Then, a new modeling algorithm for Internet router-level topology is proposed by considering the influence of both node static and dynamic properties. By means of simulations and power-law, the presented modeling algorithm is demonstrated to be capable of precisely modeling the Internet router-level topology.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133807509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is proved that rule 35, a member of Wolfram’s class II, possesses rich and complicated dynamical behaviors in its two subsystems; that is, rule 35 is topologically mixing and possesses the positive topological entropy on each subsystem. Meanwhile, the phenomena of collisions provide an intriguing and valuable bridge for proving that the union of these two subsystems is not the global attractor. Finally, it is noted that the method presented in this work is also applicable to studying the dynamics of other ECA rules, especially the 112 Bernoulli-shift rules therein.","PeriodicalId":279256,"journal":{"name":"2009 International Workshop on Chaos-Fractals Theories and Applications","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134099327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
