In this paper, we supplement the identification results for the mean treatment effect for the treated in the difference-in-differences framework studied by Abadie (2005) by establishing partial identification results for the distribution and quantile of the counterfactual outcome and of the treatment effect for the treated. Unlike the mean treatment effect which is identifiable from either the panel...
Natural gas consumption growth rate in Iran over the past decade has been usually over than the world wide consumption. As temperature variation has an inevitable effect on raw material consumption which supplies thermal and cooling energies in different areas of the society so in this research we are going to investigate the temperature effects on different sectors of natural gas consumption such...
In many Scientific and Technical endeavors a 3D object is to be reconstructed from serial 2D cross sectional data either to aid in the comprehension of the objects structure or to facilitate its automatic manipulation and analysis. The automatic reconstruction of 3D object using 2D Serial Cross Section data and Curves is presented in this paper. The 2D slices are created from Bezier Curve technique...
Creating 3D geographical simulations have been useful to many applications of geological information. Generally, typical CG simulations cannot properly and accurately represent the multilayer geographical data, due to the lack of ability to display the relations or connections between each soil layer. Also, there are errors in the position of soil layers, and classification of soil layers which does...
