in present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. for this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. to study large deformation of links, non-linear relation of displacement-s...

Abstract To study the behind armor blunt trauma (BABT), a finite element model of 5.8 mm rifle bullet penetrating SiC/UHMWPE covered human torso was established. The comprises internal organs (heart, lung, liver, and stomach), skeleton (sternum, ribs, spine), muscle. It is assumed that muscle linear elastic, all are viscoelastic hyperelastic. impact response target with bulletproof at speed 900...

For software vendors, the process to determine the requirements for the next release of a software product is often difficult. In this paper we present a mathematical formalization of release composition with a corresponding optimization tool that aims to support product managers and development project managers during release planning. The tool is based on integer linear programming and assume...

A second virial theory of the isotropic-to-nematic phase transition in solutions of slightly flexible micelles is presented. It is shown that even a infinitesimal flexibility of the micelles can suppress the divergences one would obtain when modeling the micelles as infinitely

Absfmcf -The problem of filtering and smoothing for a system described by approximately linear dynamic and measurement relations has been studied for many decades. Yet the potential problem of misspecified dynamics, which makes the usual probabilistic assumptions involving normality and independence questionable at best, has not received the attention it merits. A pmbability-free multicriteria ...

In this paper, the problem of attitude control of a 1D non-linear exible spacecraft is investigated. Three controllers are presented. The rst is a non-linear dynamic inversion, the second is a linear -synthesis and the third is a composition of dynamic inversion and a -synthesis controller. It is assumed only one reaction wheel is used. Actuator saturation is considered in the design of control...

The rapid growth of space utilization requires extensive construction, and maintenance of space structures and satellites in orbit. This will, in turn, substantiate application of robotic systems in space. In this paper, a near-minimum-time optimal control law is developed for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The time opti...
