Technological advances in any domain effects other domains as well. International law and especially international boundaries take advantage of technical progresses or considering the factors which existed before but they have been neglected and put these factors in the service of its demands. Maybe if we consider each of the technical factors separately, we cannot understand their role properly in boundary domains, but we study their setting in the form of boundaries determination and consider the package generally and investigate the relationship of internal factors. It is clear that technical factors have developed a great evolution in determination of territorial boundaries. Eventually, when the technical parameters are employed for determination of territorial boundaries, in fact they serve to its purpose; the purpose is nothing than maintaining international peace, order and security, the fact that is the existential philosophy of the United Nations organization. Thus, non-human factors have been served for human factors and maintain its values.   Definitely next advances in technical factors will be along with other revolutions in boundaries domain.

In this paper, Asymmetric buckling analysis of functionally graded (FG) Circular plates with temperature dependent property that subjected to the uniform radial compression and thermal loading is investigated. This plate is on an elastic medium that simulated by Winkler and Pasternak foundation. Mechanical properties of the plate are assumed to vary nonlinearly by temperature change. The equilibrium equations are obtained using the classical plate theory (CPT), Von Karman geometric nonlinearity and virtual displacement method. Existence of bifurcation buckling is examined and stability equations are obtained by means of the adjacent equilibrium criterion. The effects of elastic foundation coefficient, thickness to radius, power law index, and temperature-dependency of the material properties on critical buckling load of FG plates are presented. The results of the present work have been compared with the results of other investigator and the results of the comparison are very good. It is found that by increasing temperature, critical buckling load decreases. It is also concluded that the critical buckling load of (FG) Circular plates increases with an increase in the Winkler and Pasternak constants of elastic foundation.
