A constructive method for investigating if a given nonlin-ear dynamic system subject to control constraints can be controlled to follow a desired curve in the state or output space is presented. If the method gives an aarmative answer we can compute a closed form expression of the corresponding state feedback control law. Specifying a family of parametrized curves, approximations of reachable s...

at present, new tendencies in international commercial arbitration try to delocalize and gives more independence to arbitration, from national laws. the ultimate degree of this independency is demonstrated in lex mercatoria theory. in recent years this theory has been gone beyond the frontiers of pure theory and entered into the national laws of some countries such as netherlands, france and in...

Background: In the legal world, a person is not only referred to as a human being. In fact, in the world of law, a person has a more general concept that includes both human and non-human. The aim of this study was to compare real and legal personality with virtual personality from a moral perspective, as one of the important principles of Iranian law. In this regard, by understanding ethics an...

In this paper, the problem of a retaining wall under active translation mode is investigated numerically. To this end, a series of numerical models is conducted using the discrete element code, PFC2D. The backfill soil is simulated by an assembly of separate cohesionless circular particles. Backfill soil was prepared by pouring soil particles from a specific height under gravity force and givin...

We investigate the complete convergence of partial sums of randomly weighted extended negatively dependent (END) random variables. Some results of complete moment convergence, complete convergence and the strong law of large numbers for this dependent structure are obtained. As an application, we study the convergence of the state observers of linear-time-invariant systems. Our results extend t...
