This article presents the design system for high efficiency gantry crane system using elevator and conveyor system. The basic concept for the proposed gantry crane system can be used with modification of the classical gantry crane instead of changing lots of them. However, the proposed crane system can reduce the cycle time more than the classical gantry crane. The high efficiency gantry crane ...

Section 1: Introduction Analog technology is very important in commercial and industrial instruments and systems – such as measuring instruments and automatic control systems -that have analog inputs and outputs. Consumer equipment drives demand for improvements in analog circuit performance, and this naturally leads to performance improvements in commercial and industrial equipment. Fig.1 show...

Abstract—In order to verify the performance of lunar lander structure, landing-impact test is urgently needed. And the test equipment is necessary for the test. The functions and the key points of the equipment are presented to satisfy the requirements of the test, and the design scheme is proposed. The composition, the major function and the critical parts’ design of the equipment are introduc...

Semiconductor manufacturing is generally considered to be the most complex of manufacturing processes. Reasons for this include tightly constrained production processes, reentrant process flows, expensive sophisticated equipment, variable demand, high levels of automation and an ocean of data. Yet, despite the difficulties, semiconductor manufacturing is a key industry in many industrialized na...

This project presents an experimental investigations into the development proportional integral derivative (PID) control schemes for active sway control of a gantry crane system. The main objective of controlling a gantry crane is to transport the load as fast as possible without causing any unnecessary swing at the final position. The proposed controller is used as a feedback control which is ...

BACKGROUND Mechanical ventilation is a therapeutic action for newborns with respiratory diseases but may have side effects. Correct equipment knowledge and training may limit human errors. We aimed to test different neonatal mechanical ventilators' performances by an acquisition module (a commercial pressure sensor plus an isolated chamber and a dedicated software). METHODS The differences (Δ...

We study an assemble-to-order inventory system. The stocks are held for components, with final products assembled only when customer orders are realized. Customer orders form a multivariate compound Poisson process, component replenishment leadtimes are constant, and demands in excess of inventory on hand are backlogged. The component inventories are controlled by (R, nQ) policies. We show that...

INTRODUCTION Numerous emergency and transport ventilators are commercialized and new generations arise constantly. The aim of this study was to evaluate a large panel of ventilators to allow clinicians to choose a device, taking into account their specificities of use. METHODS This experimental bench-test took into account general characteristics and technical performances. Performances were ...

OBJECTIVE The study is aimed to develop and assess the quality of an evaluation form used to evaluate the nurse anesthetic trainees' skills in undertaking a pre-use check of an anesthetic machine. MATERIAL AND METHOD An evaluation form comprising 25 items was developed, informed by the guidelines published by national anesthesiologist societies and refined to reflect the anesthetic machine us...
