This book presents a systematic and comprehensive exposition of the theory of measurement accuracy and provides solutions that fill significant and long-standing gaps in the classical theory. It eliminates the shortcomings of the classical theory by including methods for estimating accuracy of single measurements, the most common type of measurement. The book also develops methods of reduction and enumeration for indirect measurements, which do not require Taylor series and produce a precise solution to this problem. It produces grounded methods and recommendations for summation of errors. The monograph also analyzes and critiques two foundation metrological documents, the International Vocabulary of Metrology (VIM) and the Guide to the Expression of Uncertainty in Measurement (GUM), and discusses directions for their revision. This new edition adds a step-by-step guide on how to evaluate measurement accuracy and recommendations on how to calculate systematic error of multiple measurements. There is also an extended section on the method of reduction, which provides an alternative to the least-square method and the method of enumeration. Many sections are also rewritten to improve the structure and usability of the material. The 3rd edition reflects the latest developments in metrology and offers new results, and it is designed to be accessible to readers at various levels and positions, including scientists, engineers, and undergraduate and graduate students. By presenting material from a practical perspective and offering solutions and recommendations for problems that arise in conducting real-life measurements, author Semyon Rabinovich offers an invaluable resource for scientists in any field.

There is a tendency to make flow measurement a highly theoretical and technical subject but what most influences quality measurement is the practical application of meters, metering principles, and metering equipment and the use of quality equipment that can continue to function through the years with proper maintenance have the most influence in obtaining quality measurement. This guide provides a review of basic laws and principles, an overview of physical characteristics and behavior of gases and liquids, and a look at the dynamics of flow. The authors examine applications of specific meters, readout and related devices, and proving systems. Practical guidelines for the meter in use, condition of the fluid, details of the entire metering system, installation and operation, and the timing and quality of maintenance are also included. This book is dedicated to condensing and sharing the authors' extensive experience in solving flow measurement problems with design engineers, operating personnel (from top supervisors to the newest testers), academically-based engineers, engineers of the manufacturers of flow meter equipment, worldwide practitioners, theorists, and people just getting into the business. The authors' many years of experience are brought to bear in a thorough review of fluid flow measurement methods and applications Avoids theory and focuses on presentation of practical data for the novice and veteran engineer Useful for a wide range of engineers and technicians (as well as students) in a wide range of industries and applications

This companion to Guides to the Evaluation of Permanent Impairment, Fifth Edition, provides instruction on a standardized method for measuring range of motion (ROM). The Guides Fifth assumes the user is experienced in measuring range of motion. This manual provides basic to proficient guidance that will enable physicians, physical therapists, and other evaluators to obtain accurate ROM measurements using standardized guidelines, reference tables, and reporting protocols. This consistent approach promises to produce greater intra- and interevaluator reliability. To increase accuracy, trained clinicians identify anatomic landmarks and properly position or stabilize the body to use a consistent technique to apply the measurement to the joint.

This short book is primarily intended to be used in undergraduate laboratories in the physical sciences. No prior knowledge of statistics is assumed, with the necessary concepts introduced where needed, and illustrated graphically. In contrast to traditional treatments a combination of spreadsheet and calculus-based approaches is used. Error analysis is introduced at a level accessible to school leavers, and carried through to research level. The emphasisthroughout is on practical strategies to be adopted in the laboratory. Error calculation and propagation is presented though a series of rules-of-thumb, look-up tables and approaches amenable to computeranalysis.

A practical reference on theory and methods of estimating measurement errors and uncertainty for both scientists and engineers in industry and experimental research. Building on the fundamentals of measurement theory, this book offers a wealth of practial recommendations and procedures. It differs from the majority of books in that it balances coverage of probabilistic methods with detailed information on the characterization, calibration, standardization and limitations of measuring instruments, with specific examples from both electrical and mechanical systems. In addition to a general updating to reflect current research, new material in this edition includes increased coverage of indirect measurements, with a new, simpler, more efficient method for this class of measurements.

Worldwide economic constraints on health care systems have highlighted the importance of evidence-based medicine and evidence-based health policy. The resulting clinical trials and health services research studies require instruments to monitor the outcomes of care and the output of the health system. However, the over-abundance of competing measurement scales can make choosing a measure difficult at best. Measuring Health provides in-depth reviews of over 100 of the leading health measurement tools and serves as a guide for choosing among them.LNow in its third edition, this book provides a critical overview of the field of health measurement, with a technical introduction and discussion of the history and future directions for the field. This latest edition updates the information on each of the measures previously reviewed, and includes a complete new chapter on anxiety measurement to accompany the one on depression. It has also added new instruments to those previously reviewed in each of the chapters in the book.LChapters cover measurements of physical disability, social health, psychological well-being, anxiety, depression, mental status testing, pain, general health status and quality of life. Each chapter presents a tabular comparison of the quality of the instruments reviewed, followed by a detailed description of each method, covering its purpose and conceptual basis, its reliability and validity and, where possible, shows a copy of the actual scale. To ensure accuracy of the information, each review has been approved by the original author of each instrument or by an acknowledged expert.
