We numerically investigate the electric potential distribution over a two-dimensional continuum percolation model between the electrodes. The model consists of overlapped conductive particles on the background with an infinitesimal conductivity. Using the finite difference method, we solve the...

Предметом исследования в статье является процесс демократизации в современном глобализирующемся мире. Глобализация теоретически изображается в виде...

Brazil has the largest stock market in South America; Argentina has one of the smallest. We investigate the spread relationship between these two markets, measured as the ratio of Brazil's Bovespa index to Argentina's Merval index. Using rescaled range analysis, we identify the presence of a...

Purpose - This paper aims at developing a behavioral agent-based model for interacting financial markets. Additionally, the effect of imposing Tobin taxes on market dynamics is explored. Design/methodology/approach - The agent-based approach is followed to capture the highly complex, dynamic...

In this study, we examined the fractal structure of the Nikkei225, HangSeng, Shanghai Stock Exchange and Straits Times Index of Singapore. Empirical analysis was performed via non-parametric, semi-parametric long memory tests and also fractal dimension calculations. In order to avoid spurious...

A continuum model that describes a disordered, heterogeneous traffic stream is presented. Such systems are widely prevalent in developing countries where classical traffic models cannot be readily applied. The characteristics of such systems are unique since drivers of smaller vehicles exploit...
