Developing economic relations with the countries of the world is necessary for any country, and the nations of the world are always looking to build their business. The expansion of the phenomenon of economic globalization has led states to engage in countries' engagement in pursuing their interests in the form of regional cooperation and the formation of monetary :union:s. Therefore, according...

The gravity model has been extensively used in international trade research for the last 40 years because of its considerable empirical robustness and explanatory power. Since their introduction in the 1960’s, gravity models have been used for assessing trade policy implications and, particularly recently, for analyzing the effects of Free Trade Agreements on international trade. The objective ...

Newton’s physical law of gravity inspired the original gravity model of economic interaction over space. The intuition was that economic flows might plausibly vary with the masses of economic activity at origin and destination and inversely with the distance between origin and destination. Newton’s Law applied strictly predicts that the economic flow Xij from origin i to destination j is Xij = ...

Trade flow has been found to be correlated with war; that is, the more trade there is between nations, the less likely they are to go to war with each other. We explore further graph analysis on a data set of trade between countries originally compiled to analyze how trade influences war alliances and country stability. What was missing from this study was seeing if war trends could have been s...

This paper models and analyzes international trade flows using open flow networks (OFNs) with the approaches of flow distances, which provide a novel perspective and effective tools for the study of international trade. We discuss the establishment of OFNs of international trade from two coupled viewpoints: the viewpoint of trading commodity flow and that of money flow. Based on the novel model...

This paper is an empirical attempt to investigate bilateral trade flow between Iran and Russia. To this end, we used statistical analyses on macroeconomic series over the period of 1991-2017. Results revealed that there is a significant statistical difference in terms of exports between Iran and Russia, and that there has always been a buyer-seller dialogue between the two countries. According ...

A computational optimization was performed for a direct-injection diesel engine using three-dimensional modeling. Fully transient CFD analyses of different valve profile strategies for the intake and compression strokes were performed to evaluate the effects on both engine performance and in-cylinder flow-field evolution. The turbulence model was used along with the second order linear upwin...
