120-1989 - IEEE Master Test Guide for Electrical Measurements in Power Circuits
Instructions are given for measuring electrical quantities that are commonly needed to determine the performance characteristics of electric machinery and equipment. Methods are given for measuring voltage, current, power, energy, power factor, frequency, impedance, and magnetic quantities, with either analog or digital indicating or integrating instruments, in DC or AC rotating machines, transformers, induction apparatus, arc and resistance heating equipment, mercury arc, thermionic, or solid-state rectifiers and inverters. Ancillary instruments and equipment are discussed. Computer-based techniques and the use of optical fibers in instrumentation are considered.
Practical Residual Stress Measurement Methods by
An introductory and intermediate level handbook written inpragmatic style to explain residual stresses and to providestraightforward guidance about practical measurementmethods. Residual stresses play major roles in engineering structures,with highly beneficial effects when designed well, and catastrophiceffects when ignored. With ever-increasing concern forproduct performance and reliability, there is an urgent need for arenewed assessment of traditional and modern measurementtechniques. Success critically depends on being able to makethe most practical and effective choice of measurement method for agiven application. Practical Residual Stress Measurement Methods providesthe reader with the information needed to understand key residualstress concepts and to make informed technical decisions aboutoptimal choice of measurement technique. Each chapter,written by invited specialists, follows a focused and pragmaticformat, with subsections describing the measurement principle,residual stress evaluation, practical measurement procedures,example applications, references and further reading. Thechapter authors represent both international academia andindustry. Each of them brings to their writing substantialhands-on experience and expertise in their chosen field. Fully illustrated throughout, the book provides a much-neededpractical approach to residual stress measurements. The material presented is essential reading for industrialpractitioners, academic researchers and interested students. Key features: * Presents an overview of the principal residual stressmeasurement methods, both destructive and non-destructive, withcoverage of new techniques and modern enhancements of establishedtechniques * Includes stand-alone chapters, each with its own figures,tables and list of references, and written by an invited team ofinternational specialists
Measurement and Instrumentation Principles by
This work aims to introduce undergraduate students to the measurement principles and the range of sensors and instruments that are used for measuring physical variables. This edition has been updated and contains worked examples and self-assessment questions (and solutions). In addition, a new chapter on safety issues focuses on the legal framework, electrical safety and failsafe designs, and the author has also concentrated on RF and optical wireless communications.
Measurement by
For seven years, Paul Lockhartâe(tm)s A Mathematicianâe(tm)s Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of Kâe"12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done. Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living. In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science. Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can âeoedo the mathâe#157; in a way that brings emotional and aesthetic rewards. Measurement is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work.
Instrumentation Reference Book by
The discipline of instrumentation has grown appreciably in recent years because of advances in sensor technology and in the interconnectivity of sensors, computers and control systems. This 4e of the Instrumentation Reference Book embraces the equipment and systems used to detect, track and store data related to physical, chemical, electrical, thermal and mechanical properties of materials, systems and operations. While traditionally a key area within mechanical and industrial engineering, understanding this greater and more complex use of sensing and monitoring controls and systems is essential for a wide variety of engineering areas--from manufacturing to chemical processing to aerospace operations to even the everyday automobile. In turn, this has meant that the automation of manufacturing, process industries, and even building and infrastructure construction has been improved dramatically. And now with remote wireless instrumentation, heretofore inaccessible or widely dispersed operations and procedures can be automatically monitored and controlled. This already well-established reference work will reflect these dramatic changes with improved and expanded coverage of the traditional domains of instrumentation as well as the cutting-edge areas of digital integration of complex sensor/control systems.
