the social security act is called as a new branch of law. one of the important sections on social security criminal act is the section 97 which in this article will be studied with the aim of explaining of the article as one of the rules of social security, pathology and extending of the law literature of social security. this study shows that, while the 97 section creates and states the new an...

In this work, we study a unilateral contact problem with non local friction of Coulombbetween a locking material and a rigid foundation. In the first step , we present the mathematicalmodel for a static process, we establish the variational formulation in the form of a variationalinequality and we prove the existence and uniqueness of the solution. In the second step, usingthe penalty method we...

This paper studies the throughput capacity and delay scaling laws in a three-dimensional mobile ad hoc network (3D-MANET) under different routing schemes. Previous work generally assumed that nodes follow uniform distribution or power-law to move network. From perspective of entire network, it is difficult for this model reflect communication entities’ real 3D space. Moreover, research results ...

abstract: a time domain semi-analytical solution to study thermoelastic creep behavior of  functionally graded rotating axisymmetric disks with variable thickness is presented. the rate type governing differential equations for the considered structure are derived and analytically solved. to solve these  equations, the disk is divided into some virtual sub-domains. general solution of  equilibr...

Abstract The contact calculation of three-dimensional real rough surfaces is the frontier field tribology and surface science. In this study, we consider interaction elastic-plastic deformation characteristics asperities further, propose an analytical method for considering asperities. Based on watershed algorithm, segmented are reconstructed into ellipsoids. According to height relationship be...

In this paper, the general problem of impedance control for a robotic manipulator with a moving flexible base is addressed. Impedance control imposes a relation between force and displacement at the contact point with the environment. The concept of impedance control of flexible base mobile manipulator is rather new and is being considered for first time using singular perturbation and new slid...
