the purpose of this study is to evaluate the impact of import of technology on iranian economy. we have used multi-sectoral and multi–regional computable general equilibrium gtap model. transfer of technology from one region to another is another factor effecting productivity. trade is one of the channels that speeds the transfer of technology. the effect of a ten percent productivity shock, in...

â â â â â â â â â â â â  abstract: â  as a result of recent developments, global economic centre of gravity has slide to asia-pacific region. it is predicted that asia-pacific countries will take place at the first row in global trade and nearly a half of the total trade will intensify in this region at the year 2030. on the other hand, the region covers countries from different levels of devel...

This paper analyzes equilibria in sequential take-it-or-leave-it sales when demand is stochastic. It is shown that equilibria in this sales mechanism, unlike in sequential auctions, trade-off allocative efficiency and competing buyers’ opportunities to acquire an item to be sold, permitting prices and expected revenue above those of one-shot offers. Hence Coase-type conjectures are invalid in t...

All practical digital circuits are usually a mixture of combinational and sequential logic. Flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. The concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

this paper explores the capabilities of multi-objective particle swarm optimization algorithmin a simulation-optimization model for solving waste load allocation problems. the main goals are totaltreatment costs, violation of the water quality standards and equity. in this research, the water qualitysimulation model is coupled with a multi-objective optimization model, mopso. in order to derive...

 Trade liberalization is often the core attention of foreign economic strategies in developing countries. Findings in the literature confirm a significant effect of free trade on developing economies through which the economic sectors benefit from technology transfer and spillovers and increasing production capacities and input productivity leading to international competitiveness. On the other...

electroencephalogram (eeg) is one of the useful biological signals to distinguish different brain diseases and mental states. in recent years, detecting different emotional states from biological signals has been merged more attention by researchers and several feature extraction methods and classifiers are suggested to recognize emotions from eeg signals. in this research, we introduce an emot...

We examine a standard, gravity model of international commerce, augmented to include political as well as institutional influences on bilateral trade. Using annual data from 1980-2001, we estimate regression coefficients and residual dependencies using a hierarchy of models in each year. Rather than gauge the generalizability of these patterns via traditional measures of statistical significanc...
