Simulation of pedestrian counter-flow with right-moving preference

Yang, Lizhong; Li, Jian; Liu, Shaobo - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 13, pp. 3281-3289

counter-flow in a channel is simulated with the Cellular Automata (CA) Model, with focus on right-preference. Two types of … respectively. The right-preference intensity, k, is introduced, defined as the ratio of the right-moving probability to left … right-preference is effective when the density is below critical. The model is shown to be useful to simulate and analyze …

Synergetic behavior in the cascading failure propagation of scale-free coupled map lattices

Bao, Z.J.; Cao, Y.J.; Ding, L.J.; Wang, G.Z.; Han, Z.X. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 23, pp. 5922-5929

In this paper, the whole dynamical process of cascading failures in a class of scale-free coupled map lattices (CML’s), from the occurrence of attack to the end of failure propagation, is investigated. A dynamical model of cascading failures, based on synergetic theory, is constructed....

Dynamics of cluster structures in a financial market network

Kocheturov, Anton; Batsyn, Mikhail; Pardalos, Panos M. - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 523-533

In the course of recent fifteen years the network analysis has become a powerful tool for studying financial markets. In this work we analyze stock markets of the USA and Sweden. We study cluster structures of a market network constructed from a correlation matrix of returns of the stocks traded...

Reciprocity relations in thermodynamics

Grmela, Miroslav - In: Physica A: Statistical Mechanics and its Applications 309 (2002) 3, pp. 304-328

Dissipative time evolution of macroscopic systems describing the experimentally observed approach to reduced descriptions is put into the context of contact geometry. This viewpoint of nonequilibrium thermodynamics unifies many well-established mesoscopic dynamical theories, as for example the...

On the stock market recurrence

Baptista, M.S; Caldas, I.L - In: Physica A: Statistical Mechanics and its Applications 284 (2000) 1, pp. 348-354

We analyze the return of the S & P 500 index and characterize its evolution as being typical of a low-dimensional recurrent deterministic system. The first Poincaré return time of the chaotic logistic mapping trajectories is used to model the return evolution. The efficiency of the model is...
