Coordinated manipulators can construct a series system, such that all the position error of end-effector is required to remain within permissible limit. This article proposed new method handle problem reliability analysis involving in multiple failure modes. The extreme value introduced surrogate model replace original event, moment with fraction order instead traditional integer applied derive...

mhd boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. a system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order rung...

The gravitational clustering of collisionless particles in an expanding universe is modelled using some simple physical ideas. I show that it is indeed possible to understand the nonlinear clustering in terms of three well defined regimes: (1) linear regime (2) quasilinear regime which is dominated by scale-invariant radial infall and (3) nonlinear regime dominated by nonradial motions and merg...

The paper is aimed at investigating the motion conditions of wheeled vibro-impact locomotion system equipped with twin crank-slider excitation mechanism and additional braking mechanisms allowing only one-way rotation wheels. novelty present research consists in improved mathematical model describing proposed parameters optimization technique that allows for maximizing average translational vel...

during the past decades, attempts have been made to develop an early warning system for coming destructive earthquakes a few seconds before the ongoing ground motion. in this paper, a practical method for the early warning of earthquakes in south iran is presented. this region is selected for study because it has high potential for generating earthquakes and has a more complete strong ground mo...
