industrial revolution, colonialism and spreading of patterns of development and consequently the vast rural and urban migrations and centralism in recent century caused the creation of unbalanced population distribution pattern in iran. in addition to areas in which inequalities of environmental and productive resources increase space disparity of distribution of populations, in arease like aze...

We modify the epistemic conditions for Nash equilibrium only to accommodate Gilboa and Schmeidler’s [Journal of Mathematical Economics, 18 (1989), 141–153] maxmin expected utility preferences, and identify the equilibrium concept in n-player strategic games that characterizes the modified epistemic conditions. The epistemic characterization supports the equilibrium concept as a minimal generali...

in this study, mass transfer coefficients (mtc’s) of natural gas components during hydrate formation are reported. this work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...

be viewed within a much larger system of reliability analysis, generalizability theory. Moreover, alpha focused attention on reliability coefficients when that attention should instead be cast on measurement error and the standard error of measurement. For Cronbach, the extension of alpha (and classical test theory) came when Fisherian notions of experimental design and analysis of variance wer...

Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...

We consider precautionary liquidity holding as counter-strategy for the entrant to protect himself from predation. Threat of predation, even if avoided in equilibrium, affects the financial contract to raise precautionary liquidity and the equilibrium outcome in the product market competition. When the incumbent’s strategy is unverifiable, the entrant with small start-up capital cannot raise la...

in this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (swcnt) in a square arrays. to this aim, we have employed equilibrium molecular dynamics (md) simulation. our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...

One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...
