Nonrestricted hierarchical three-body configurations are common in various scales of astrophysical systems. Dynamical structures the quadrupole-order resonance (the von Zeipel-Lidov-Kozai resonance) and octupole-order apsidal under nonrestricted planetary systems investigated this work by taking advantage perturbative treatments. Under Hamiltonian model, distribution libration circulation regio...

The COVID-19 has renovated the debate about global health governance. Many scholars have proposed that World Health Organization (WHO) should assume position of a central coordinator with hierarchical powers. This article presents four main objections to this project: problems ‘one-size-fits-all’ policies, heterogeneous distribution power within multilateral institutions, risks crowding out par...

The hierarchical hub covering facility location problems are applied to distribution systems, transportation, waste disposal, treatment services, emergency services and remote communication. The problems attempt to determine the location of service providers' facilities at different levels and specify their linking directions in order to reduce costs and to establish an appropriate condition in...

this paper analyzes the reaction of the 9th government with workers and capitalists using game theory. the type of game between three players is static with perfect information. strategy of the players is determined through the use of hierarchical processes and network analysis method. the equilibrium between these three players is the nash type of equilibrium. in the hierarchical and network a...
