We analyse the structure and behaviour of a specific voting network using a dynamic structure-based methodology which … draws on Q-Analysis and social network theory. Our empirical focus is on the Eurovision Song Contest over a period of 20 … voting groups emerge. We investigate structures that may identify the winner based purely on the topology of the network …

In this paper, we investigate the correlation structure and dynamics of international real estate securities markets by … using daily returns of 20 national markets during the period 2006–2012 from a network perspective. We construct the minimum … examine the dynamics of correlation structure. The empirical results show that (1) the distribution of correlation …

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....

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 … chaotically, while during crises they show more stable behavior and fewer changes. Thus an increasing stability of a market graph …

The analysis of dynamics in traffic flow is an important step to achieve advanced traffic management and control in … Intelligent Transportation System (ITS). Complexity and periodicity are definitely two fundamental properties in traffic dynamics … of weekdays and weekends in traffic flow data. The findings in this paper indicate that complex network is a practical …

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...

We apply methods and concepts of statistical physics to the study of economic organizations. We identify robust, universal, characteristics of the time evolution of economic organizations. Specifically, we find the existence of scaling laws describing the growth of the size of these...

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...
