in this paper, the problem of finite time stabilization for guidance system is investigated and a novel nonlinear guidance law against maneuvering targets is proposed based on the principles of parallel navigation. the proposed law is developed using two variable structure control techniques. by applying finite time integral sliding mode and combining it with terminal sliding mode, a new guidan...

Background: All nursing cares require decision-making, and the ability to make the best decisions impact upon the quality of nursing care. Moreover, authenticity and accuracy of the best cares may be questioned if not recorded and reported properly and in a standard manner. We aimed to design and implement an electronic nursing managementsystem and then evaluate satisfaction of nurses with the ...

While ultrasound guided prostate brachytherapy has gained wide acceptance as a primary treatment tool for prostate cancer, quality assurance of the ultrasound guidance system has received very little attention. Task Group 128 of the American Association of Physicists in Medicine was created to address quality assurance requirements specific to transrectal ultrasound used for guidance of prostat...

in this research we have presented a local model for implementing systems engineering activities in optimized acquisition of electronic systems in electronic high-tech industrial. in this regard, after reviewing the literature and the use of documents, articles and latin books, we have collected system acquisition life cycle models from different resources. after considering the criteria of the...

In this paper a new nonlinear guidance law with finite time convergence is proposed. The second order integrated guidance and control loop is formulated considering a first order control loop dynamics. By transforming the state equations to the normal form, a finite time stabilizer feedback linearization technique is proposed to guarantee the finite time convergence of the system states to zero...

This publication is aimed at managers in all industries. It explains why human factors are important in health and safety and how they need to be assessed and managed in the same way as other risk factors. It gives practical advice on how to develop systems designed to take account of human capabilities and fallibilities. All rights reserved. No part of this publication may be reproduced, store...
