NEW NIST PRACTICE GUIDE ON ROCKWELL HARDNESS TESTING AVAILABLE The NIST Recommended Practice Guide: Rockwell Hardness Measurement of Metallic Materials
WANTED: MEASUREMENTS WITH GOOD REFERENCES In nearly all types of activities-be they related to manufacturing, finance, health, regulatory affairs or even sports-people and organizations are becoming sticklers for measurement uncertainty. NIST, the nation’s measurement authority, has responded to this growing customer need for demonstrable uncertainty. It has created an on-line resource— www.nis...
متن کاملCapability in Rockwell C Scale Hardness
A measurement system is capable if it produces measurements with uncertainties small enough for demonstration of compliance with product specifications. To establish the capability of a system for Rock-well C scale hardness, one must assess measurement uncertainty and, when hardness is only an indicator, quantify the relation between hardness and the product property of real interest. The uncer...
متن کاملthe effect of esp materials on medical studentsreading proficiency
چکیده این تحقیق " مواد درسی " را به عنوان یکی از بحث برانگیزترین موضوعات آموزش زبان تلقی کرده و درتلاش است به سه سوال عمده پاسخ دهد: 1) آیا بکارگیری جزوات گرداوری شده توسط گروهی از مدرسین تاثیر بسزایی در میزان توانش خواندن و درک متون انگلیسی دانشجویان پزشکی دارد؟ 2) آیا استفاده از مواد درسی اصلی( بین المللی )، توانش خواندن و درک متون انگلیسی دانشجویان پزشکی را به طور چشمگیری تحت تاثیر قرار م...
15 صفحه اولthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
