By considering the fact that the surface tension of a real fluid arises from a combination of both repulsive and attractive forces between molecules, a new expression for the interfacial tension has been derived from scaled particle theory (SPT)  based on the work of cavity formation and the interaction energy between molecules. At the critical temperature, the interfacial tension between c...

An extremely large body of theoretical work exists on pattern formation, but very few experimental results have confirmed the relevance of theoretical models. It is argued in this article that the notion of agent-based pattern formation, which is introduced and exemplified, can serve as a basis to study pattern formation in nature, especially because pattern-forming systems based on agents are ...

Many workers hear about or obtain their jobs through friends and relatives. The aim of this paper is twofold. First, we relate both individual and aggregate labor market outcomes to the network structure of personal contacts. Second, we study strategic network formation. To this purpose, we develop a model specifying at the individual level both the decision to form contacts with other agents, ...

the density functional theory (dft) and the natural bond orbital (nbo) calculations basedmethod b3lyp/6-31g* were carried out to study the interaction of carbon nanotube (8,0) withnitrobenzene in two situations perpendicular and parallel. formation energies of compounds,charges, the highest occupied molecular orbital (homo) and the lowest unoccupied molecular'orbital (lumo) and the homo-lumo ba...

in this paper, we have studied the effect of population on iranian economic growth by using optimal growth theory. optimal growth theory is a nonlinear dynamic planning. classical approaches in mathematics are used for solving these nonlinear systems. but, in this study, we have used genetic algorithm (ga) method. as results show, it seems that population growth in previous years (1350- 1386), ...

This paper assumes the cell formation problem as a distributed decision network. It proposes an approach based on application and extension of information theory concepts, in order to analyze informational complexity in an agent- based system, due to interdependence between agents. Based on this approach, new quantitative concepts and definitions are proposed in order to measure the amount of t...
