T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy inform...

Quadruped robots have unique capabilities for motion over uneven natural environments. This article presents a stable gait for a quadruped robot in such motions and discusses the inverse-dynamics control scheme to follow the planned gait. First, an explicit dynamics model will be developed using a novel constraint elimination method for an 18-DOF quadruped robot. Thereafter, an inverse-dynamics...
