Reducing Lead Time for Electrical Switchgear
This paper highlights some of the key problems in reducing lead times for engineered-toorder construction products, specifically items of equipment such as electrical switchgear (“permanent plant equipment” in the jargon of the process industries). Lead time reduction has long been considered a fundamental objective in overall business improvement and is a cornerstone in lean thinking. The bene...
متن کاملLead and Lead Poisoning from Antiquity to Modern Times
Lead, because of its low melting point, was one of the first metals used by man. It was probably isolated soon after the ancients discovered the use of fire. Archeological discoveries indicate the presence of lead objects and pigments during the early Bronze Age. In ancient Egyptian and Greco-Roman times metallic lead was produced as a by-product of silver mining. Extensive evidence of ancient ...
متن کاملCalculating bone-lead measurement variance.
The technique of (109)Cd-based X-ray fluorescence (XRF) measurements of lead in bone is well established. A paper by some XRF researchers [Gordon CL, et al. The Reproducibility of (109)Cd-based X-ray Fluorescence Measurements of Bone Lead. Environ Health Perspect 102:690-694 (1994)] presented the currently practiced method for calculating the variance of an in vivo measurement once a calibratio...
متن کاملReducing the Variance of Sojourn Times in
In a queueing network with overtaking, the probabilistic eeects entailed by a customer propagate in such a manner that the sojourn time of the same customer in a node visited later is aaected. The main eeect of overtaking is the dependency of node sojourn times on non-overtake-free paths: the sojourn time distribution of a non-overtake-free path is not simply the convolution of the sojourn time...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
