摘要

The main objective of this study is to assess the implementation of 5S and development of the 5S Activity Checklist in manufacturing companies. The scope for this study covers the following areas: identifying problems, looking into critical success factors, their outcomes and recommendations. In addition, factors that may act as constraints to the implementation of the 5S activity and possible solutions for the industries are also identified through observation and evaluation of the improved environmental performance. The study is conducted using a systematic approach with specific software in order to get the most accurate results. × Copy and Paste Sandip K.

This network is used to collect and send various kinds of messages to a base station (BS). WSN consists of low-cost nodes with limited battery power, and the battery replacement is not easy for WSN with thousands of physically embedded nodes, which means energy efficient routing protocol should be employed to offer a long network life time. The lifetime of Wireless Sensor Networks (WSN) is crucial. To achieve the aim, we need not only to minimize total energy consumption but also to balance WSN load. Hence, this paper aims to study different energy balance routing protocols of WSNs. In this paper, we have compared different protocols of WSN, ensuring maximum network lifetime by balancing the load as equally as possible Keywords— Energy-balance, network lifetime, routing protocol, wireless sensor network × Copy and Paste Sheetal Watkar, Prof. B.G.Hogade, Prof.Hemangi Satam, "Review Paper on Energy Efficient Protocol in Wireless Sensor Network" Vol. 5 - Issue 3 (March - 2015), International Journal of Engineering Research and Applications (IJERA) , ISSN: 2248-9622 , www.ijera.com × Three Dimensional Modelling of MISFET Preetam Jain, Lochan Jolly [ Abstract ] [ PDF ] [ Cite ] Abstract: Recent research shows the tremendous potential for the development of optical devices viz. photo-detector, optical sources, connectors and applications etc. This is mainly because of the success of optical communication in the recent for gigabit transmission and is intended for terabits transmission in future. In this paper, mathematical model for the optical dependence of I-V, C-V characteristics of MISFET structure (to be used as photo-detector) is reported. Model is based on solution of Poisson?s and current continuity equation. Proposed structure of MISFET includes, In_0.53Ga_0.47As used as substrate material and InP as insulator. Light is made to incident perpendicular to the surface. Drain current can be controlled optically by means of varying light intensity of incident radiation. There is significant effect of intensity modulation on IV and CV characteristics of MISFET. As a result of intensity modulation, drain current increases significantly in presence of illumination mainly due to change in carrier concentration of channel results from photo-generated carriers. Simulation of mathematical model is carried out in MATLAB.

Naser R. M. AL-Ajmi [ Abstract ] [ PDF ] [ Cite ] Abstract: Refrigerator is one of the home appliance utilizing mechanical vapor compression cycle in its process. Performance of the systems become the main issue and many researches are still ongoing to evaluate and improve the efficiency of any used system. Therefore, this paper presents an experimental investigation of the performance of the refrigeration cycles. A small rrefrigerator is used as the test rig. The Coefficient of Performance (COP) is studied by using different condenser designs and under varying evaporator loads. Three condenser designs are used in present work. These condensers are regular condenser of domestic refrigerator, condenser with copper plain tubes (Cond.1) and condenser with copper tubes welded with stainless steel flat plate (Cond.2). pressures and temperatures measurements of each point in the refrigeration cycle are collected in order to evaluate the refrigerator performance. The results showed that the average COP of Cond.1 and Cond.2 are increased up to 20 % and 14% respectively more than regular condenser design under no load. The eva
