Electronic Measurement Systems: Theory and Practice, Second Edition
is designed for those who require a thorough understanding of the
wide variety of both digital and analogue electronic measurement
systems in common use. The first part of the book discusses basic
concepts such as system specification, architectures, structures,
and components. Later chapters cover topics important for the
proper functioning of systems including reliability,
guarding/shielding, and noise. Finally, an unusual chapter treats
the problems of the human aspects of the design of measurement
systems. The book also includes problems and exercises.
From the Author's Preface
Techniques and Topics in Flow Measurement covers the applications
and techniques of flow measurement. This definitive book provides
guidelines for choosing appropriate techniques and assuring valid
measurements as well as describes methods for treatment of
calibration data in fluid flow under various conditions. The book
also covers three systems of units: the SI system, the English
Absolute Dimensional system, and the English Engineering system.
Commonly used - and often misused - variables such as force,
weight, and pressure are defined, and the relationships between the
systems for these common variables are summarized.
Explaining the symbology of dimensioning and tolerancing and introducing a step-by-step system for geometric definition, this book provides examples for the application of geometric controls. The author breaks down the language of geometric product definition into a series of steps that consist of significant questions to be asked at any point in the product definition. He addresses functional requirements and manufacturing techniques, measurement, inspection, and gaging procedures. The book illustrates how symbology is best utilized, in what order it should be applied, and how each geometric control anticipates, integrates, and complements all other geometric controls on a part and in an assembly.
Can the newborn infant accurately record traumatic experience? Can early traumas be retained in memory? How would such traumatic memories affect later development? Where should we look for evidence of such traumas in adult patients? If Someone Speaks, It Gets Lighter provides surprising answers to these questions. Taking as her point of departure both her own clinical experience and case reports in the analytic literature, Lynda Share provides a thorough, at times revelatory, examination of the basic issues. She proposes that the controversy between narrative and historical truth be redefined in terms of the distinctly different memory systems involved and in terms of the special mechanisms whereby trauma, as opposed to ordinary expectable experience, becomes a major unconscious organizer of behavior and memory. Then, winding her way skillfully through contemporary debates about the limits of reconstruction, she argues persuasively that the impact of early infantile trauma can become accessible through disciplined analytic inquiry. Indeed, for Share, to forego the possibility of reconstructing such traumas in favor of an exclusively here-and-now interpretive approach is to risk perpetuating the trauma in all its pathogenicity. By contrast, when trauma can be reexperienced meaningfully in treatment, both behavioral reenactments and trauma-related transference issues can be dramatically clarified. Demonstrating her point with vivid clinical case reports, Share emphasizes the special value of dream interpretation in recovering the full psychological impact of events that occurred in the first few years of life. Through the imagistic dimension of dream formation, unconscious traumaticmemories gain access to an expressive vehicle through which the patient, aided by the analyst's understanding, can begin to work through early experiences that have heretofore been dimly known but not felt. At once a return to the intuitions of the early psychoanalytic pioneers and a foray into the recent insights of developmental psychology, If Someone Speaks, It Gets Lighter integrates scientific research with contemporary psychoanalytic theory to reclaim an important area of therapeutic intervention. Specifically, Share's framework enables analysts and therapists to realize the clinical imperative of helping patients move beyond the unconscious limits laid down by their earliest histories.
For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives-and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari's castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries-and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.

A guide to the use of the new Civil Engineering Standard Methods of Measurements, this also includes a listing of alternative methods of measurement where circumstances require it. General information on measurement is included but the core of the book lies in its coverage of all the sections in the Standard, including explanations of the measurement corrections, drawings and model take-offs (with notes), model bills (with abstracts if needed) and a standard library of descriptions.
All measurements are subject to error because no quantity can be
known exactly; hence, any measurement has a probability of lying
within a certain range. The more precise the measurement, the
smaller the range of uncertainty. Uncertainty, Calibration and
Probability is a comprehensive treatment of the statistics and
methods of estimating these calibration uncertainties.

This volume is a valuable, single source of information on the most common flow-induced vibration problems in power and process plant components. Based on the author's own experience that most errors in engineering analysis come from confusions in the units, the author begins with a short chapter on units and dimensions. He then provides step-by-step examples in dual US and SI units, leading to the final objective of design analysis, problem solving, diagnosis and trouble shooting in the following areas: fundamentals of vibration; acoustics and structural dynamics; vibration of structures in quiescent fluids; vortex-induced vibration; turbulence-induced vibration; impact, fatigue and wear caused by flow-induced vibration; acoustically induced vibration; and signal analysis and diagnostic techniques. Emphasis is placed on the physics of the phenomenon and most of the work examples can be solved with pocket calculators.
This book offers an in-depth discussion related to metrological aspects of automated tests. The accuracy of experimental estimates of test object performance is examined from the standpoint of their statistical variance and systematic biases. The proposed metrological model of automated tests allows to determine the metrological characteristics of measurement means using data from their static and dynamic calibrations. Knowledge of these characteristics provides an ability to examine their impact on the accuracy of test results for the purposes of estimating statistical uncertainties caused by instrumentation errors and eliminating biases that occur as a consequence of inertial properties of measurement means. Optimization of requirements for measurement errors to ensure a given accuracy of test results is discussed as well. Proposed approaches and described methods are illustrated by test examples of turbomachinery products.
This book provides the basic concepts and fundamental principles of dynamic systems including experimental methods, calibration, signal conditioning, data acquisition and processing as well as the results presentation.
