Synchronization in a power-driven moving agent network

Shi, Huan; Wang, Lei; Dai, Hua-ping; Sun, You-xian - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3094-3100

Motivated by the fact that couplings between individual units of many real-world complex systems are relevant to energy, we propose a power-driven moving agent network model as a simple representation. The presented network exhibits a directed and time-varying topological structure, where each...

ONE-TO-MANY NODE MATCHING BETWEEN COMPLEX NETWORKS

DU, FANG; XUAN, QI; WU, TIE-JUN - In: Advances in Complex Systems (ACS) 13 (2010) 06, pp. 725-739

Revealing the corresponding identities of the same individual in different systems is a common task in various areas, e.g., criminals inter-network tracking, homologous proteins revealing, ancient words translating, and so on. With the reason that, recently, more and more complex systems are...

IDENTIFYING THE LARGE-SCALE STRUCTURE OF THE BLOGOSPHERE

UCHIDA, MAKOTO; SHIBATA, NAOKI; KAJIKAWA, YUYA; TAKEDA, … - In: Advances in Complex Systems (ACS) 12 (2009) 02, pp. 207-219

We analyze a topological structure of networks formed according to the entries and trackbacks in the blogosphere, which is a collection of weblog articles. The analysis is performed based on community extraction, network visualization and keyword analysis. It is shown that the large-scale...

On synchronizability and heterogeneity in unweighted networks

Hao, Binbin; Yu, Hao; Jing, Yuanwei; Zhang, Siying - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 9, pp. 1939-1945

Synchronization in classes of continuous-time dynamical unweighted networks with different topologies is investigated. A synchronization-optimal network model based on rewiring of links is proposed. Compared with other networks, it exhibits a stronger synchronizability. We presented link density...

Modeling human dialogue–the case of group communications in trunked mobile telephony

Xenikos, D.G. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 23, pp. 4910-4918

In this report we study the dynamics characteristics of conversations among several participants, analyzing trunked mobile telephony databases. We find that the duration of the dialogue sessions deviates systematically from the predictions of Poisson statistics, following probability...

Growing community networks with local events

Xu, Xin-Jian; Zhang, Xun; Mendes, J.F.F. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 7, pp. 1273-1278

The study of community networks has attracted considerable attention recently. In this paper, we propose an evolving community network model based on local processes, the addition of new nodes intra-community and new links intra- or inter-community. Employing growth and preferential attachment...
