This book offers professionals and students a comprehensive overview of GPS signal acquisitions, measurements, and algorithms for estimation of dynamic programming, quality control, and filtering methods. This book discusses in-depth GPS signal transmissions, transmission procedures and calculation algorithms, using GPS positioning location data for empirical research to elucidate various dimensions of spatial phenomenon which is different from previously published books. This book also focuses on how to conduct empirical research with GPS collected data to contribute discipline theory and concepts in different domains. The book is divided into three parts. Part I introduces debates about measurements of GPS signal structure, including acquisition time, validity based on various tested GPS units, quality control of real-time positioning, data characteristics of probed density, average time, and signal disturbance of message distribution such as noise and inaccuracy positioning. Part II describes applications of GPS positioning data for monitoring analysis, movement analysis, spatial analysis and clustering analysis. Part III presents GPS sources of error and biases by discussing the technology of positioning location for underwater positioning, and clarifying the accuracy of digital maps to positioning systems for vehicle positioning. This book brings together a team of leading experts who perform a creative and empirical research of Global Positioning Systems. The book aims to share all the latest advances in systems, methods and application of GPS positioning with the readers. The topics in this book cover an integrated overview of GPS conceptions, an in-depth realisation of advanced application, and the emerging trends in GPS research.

The inclusion of an electrical measurement course in the undergraduate curriculum of electrical engineering is important in forming the technical and scientific knowledge of future electrical engineers. This book explains the basic measurement techniques, instruments, and methods used in everyday practice. It covers in detail both analogue and digital instruments, measurements errors and uncertainty, instrument transformers, bridges, amplifiers, oscilloscopes, data acquisition, sensors, instrument controls and measurement systems. The reader will learn how to apply the most appropriate measurement method and instrument for a particular application, and how to assemble the measurement system from physical quantity to the digital data in a computer. The book is primarily intended to cover all necessary topics of instrumentation and measurement for students of electrical engineering, but can also serve as a reference for engineers and practitioners to expand or refresh their knowledge in this field.

Experimental Methods for Engineers, 8/e, offers the broadest range of experimental measurement techniques available for mechanical and general engineering applications. Offering clear descriptions of the general behavior of different measurement techniques, such as pressure, flow, and temperature, the text emphasizes the use of uncertainty analysis and statistical data analysis in estimating the accuracy of measurements. Maintaining its thorough coverage of thermal-fluid measurement techniques, the text continues to emphasize experimental uncertainties as essential elements in experiment design, execution, and instrument selection.

How do you draw a straight line? How do you determine if a circle is really round? These may sound like simple or even trivial mathematical problems, but to an engineer the answers can mean the difference between success and failure. "How Round Is Your Circle?" invites readers to explore many of the same fundamental questions that working engineers deal with every day--it's challenging, hands-on, and fun.

John Bryant and Chris Sangwin illustrate how physical models are created from abstract mathematical ones. Using elementary geometry and trigonometry, they guide readers through paper-and-pencil reconstructions of mathematical problems and show them how to construct actual physical models themselves--directions included. It's an effective and entertaining way to explain how applied mathematics and engineering work together to solve problems, everything from keeping a piston aligned in its cylinder to ensuring that automotive driveshafts rotate smoothly. Intriguingly, checking the roundness of a manufactured object is trickier than one might think. When does the width of a saw blade affect an engineer's calculations--or, for that matter, the width of a physical line? When does a measurement need to be exact and when will an approximation suffice? Bryant and Sangwin tackle questions like these and enliven their discussions with many fascinating highlights from engineering history. Generously illustrated, "How Round Is Your Circle?" reveals some of the hidden complexities in everyday things.

Interest in the applications of ultrawideband (UWB) radar systems is increasing rapidly all over the world. This is evident from the number of monographs recently published on the subject and from the many papers presented at international conferences on the general problems involved in UWB radar and on its promising new applications. Conventional (classical) methods seem to have exhausted their potential and studies in the field are undergoing a profound change. This book presents some of the novel approaches to radar system analysis now being investigated. A good source of information on UWB signals is their structural analysis in the time domain. This allows a greater understanding of the specific features of UWB radar systems, such as the properties of receiving and transmitting antennas, and various characteristics of near- and far-range target scattering fields. It is shown how the systematic application of numerical procedures can provide new results in the evaluation of UWB radar target responses. The authors do not try to cover all of the possible solutions to the problem of multidimensional representation of target responses; rather they aim to give a general understanding of the techniques of confluent analysis, computer holography and adaptive synthesis of antenna apertures. These methods have great potential for solving conventional radar problems in target detection and recognition, and they are sure to stimulate the use of UWB signals in many fields such as subsurface probing and ecological monitoring.

RECENT CASTASTROPHIC STRUCTURAL FAILURES, OCCURING ACROSS MANY INDUSTRIES, HIGHLIGHT THE NEED FOR SOCIETY TO RELATE RISK MORE EXPLICITLY WITH INSPECTION PROGRAMS. THIS VOLUME DESCRIBES AND RECOMMENDS APPROPRIATE PROCESSES AND METHODS USING RISK-BASED INFORMATION TO ESTABLISH INSPECTION GUIDELINES FOR FACILITIES OR STRUCTURAL SYSTEMS.

During the 1980s, the worldwide interest in electromagnetic compatibility (EMC) grew rapidly with the introduction of legislation to control the growing interference problems generated by the increased use of electronic equipment in industry and in the home. The European directive harmonizing EMC measurements gave particular impetus to manufacturers and importers of electrical and electronic equipment in Europe to understand EMC design techniques and verification procedures. This book explains how equipment can be verified by testing. It discusses the nature of EMC standards world wide and describes in detail testing methods and their conduct and accuracy. In addition to standard EMC testing, topics including electrostatic discharge, nuclear electromagnetic pulse and lightning are also discussed. In the broad span of its subject matter, the interests of equipment manufacturers, EMC test engineers, project managers and company administrators are addressed. The testing of both military and commercial electronic equipment is covered. Particular emphasis is placed on the nature of EMC test equipment and how to use it to make reliable measurements.

The need to measure electrical power is common to many branches of science and engineering. This book presents a wide-ranging survey of the many types of radio-frequency and microwave power meter and the techniques which are used for calibrating and intercomparing them. The frequency range is 1 MHz to 200 GHz. The first of the sixteen chapters considers the fundamentals. Four chapters are then devoted to the subject of calorimetry, which forms the basis of the majority of primary standards for power measurement. A further five chapters describe the various types of non-calorimetric power meter, which include not only the commonly used thermistor, thermoelectric and diode types, but also force-operated instruments and a considerable number of miscellaneous devices. Calibration and intercomparison methods are covered in three closely linked chapters which treat respectively the basic techniques, the use of reflectometers for power meter calibration, and the problems associated with connectors and adapters. In the last three chapters a mixture of topics is covered. First a concise survey of pulsed power measurements is presented. Attention is then given to the topics of voltage and current measurement, which are closely related to power measurement. Finally, the subject of the international intercomparison of standards is discussed and the results of some of the more important intercomparison exercises are summarised.

This complete, well-integrated text offers students without extensive background in the field a solid understanding of the principles and applications of analog and digital instrumentation. Examines such topics as basic analog and digital electronic components, systems theory, and the design of analog signal conditioning circuitry for amplification, filtering, and level shifting of signals originating from a variety of transducers. Includes a detailed description of how to interface analog-to-digital converters to a personal computer, in order to digitize and display these signals, store them on magnetic media, and perform elementary digital filter operations. Also provides a review of operational amplifiers, instrumentation amplifiers, and systems theory. Numerous examples and problems are presented throughout the text, and laboratory experiments concluding each chapter provide ``hands on'' experience in all areas covered.

Starting with the useful concept of an elementary integral defined (axiomatically) on a family of elementary functions, this treatment examines the general theory of the integral, Lebesque integral in n space, the Riemann-Stieltjes integral, and more. "The exposition is fresh and sophisticated, and will engage the interest of accomplished mathematicians." - Sci-Tech Book News. 1966 edition.

Measurement uncertainty is an important component of modern materials analysis: it indicates the boundaries within which the test results can be trusted. Such results are necessary for understanding of, for example, material and product tolerances and lifetimes, vital for plastic product reliability and safety. Determination of measurement uncertainty is normally quite laborious, but this book shows how the available interlaboratory test data for plastics can be used to calculate measurement uncertainty much more simply. It contains many interlaboratory test results in the fields of thermoanalysis, molar mass determination, and quantitative analysis of the composition of material, presented in tables and graphical charts, discussed in the text, and elaborated by practical examples. In addition to the evaluation by means of the presented data (top-down approach), the relationship to the bottom-up approach specified in the Guide to the Expression of Uncertainty in Measurement (GUM) is explained based on an example. Further sections deal with sampling, and the issue of whether or not the difference between analytical results is significant.

Fur akustische Planungen ist es unerlasslich zu wissen, wie viel Schall eine Quelle abstrahlt. Auch die Wahl einer gerauscharmen Maschine ist nur moeglich, wenn die jeweiligen Herstellerangaben miteinander vergleichbar sind. Die Schallleistung ist in beiden Fallen die passende Groesse, da sie die Schallabstrahlung einer Quelle unabhangig vom umgebenden Raum beschreibt. Gerade diese Ortsunabhangigkeit ist aber erforderlich, um mehrere Quellen zuverlassig vergleichen zu koennen oder um z.B. die an einem Arbeitsplatz in einer Werkhalle oder an einem Immissionsort in der Nachbarschaft zu erwartenden Gerauschimmissionen prognostizieren zu koennen. In dem Band "Schallleistung" werden die theoretischen Grundlagen erlautert und verschiedene, grundlegende Messmethoden vorgestellt. Damit wird die Leserin oder der Leser in die Lage versetzt, das fur eine spezifische Messaufgabe passende Messverfahren auszuwahlen und, falls in den einschlagigen Regelwerken keine Vorgaben fur besondere Einzelfalle zu finden sind, angepasste Loesungen zu erarbeiten, die mit den jeweiligen Messprinzipien in Einklang stehen.

In diesem Band der Reihe Fachwissen Technische Akustik werden Grundlagen der Abtastung und Quantisierung, digitale Filter sowie mehrere digitale Signalverarbeitungsmethoden beschrieben: Echtzeit-Frequenzanalysator, 2-Kanal-FFT-Analysator mit Sweep- oder Rauschanregung und Maximalfolgenmesstechnik. Anwendungen und Fehlerquellen der digitalen Messverfahren werden an Beispielen diskutiert.

A calibration procedure is generally an operation to determine a relationship between an output and an input of an instrument or an essential value of a measuring object in a measuring system. In other words, calibration is a comparison of a measuring device against a standard instrument of higher accuracy. In measuring fields, the calibration is clearly confirmed in the traceability system. The traceability is defined as the property of a result of a measurement whereby it can be related to strictly defined standards, in general, nationally or internationally recognised, through an unbroken chain of comparisons. Namely, all calibrations are strictly defined to be performed traceable to a nationally or internationally recognised standard in a measuring field. The term "calibration" is used not only in measuring fields but also in meteorology, chemistry and economics. Also, in these fields the term "calibration" is used as an operation to adjust and/or compensate a measuring system, and a method for accurately determining the relational expression between an input/output of an instrument using suitable standards, for example, an appropriate global optimisation method. However, compared to the measuring field, in these other research areas the calibration seems to be defined in a less systematic way, possibly due to the different nature of these disciplines. In this volume, calibration is defined in the above-mentioned broad sense of the term, and the topics for discussion are broad and abundant. The standard of calibration as a method which is confirmed systematically in the measurement field has been developing also in other disciplines. They have many research issues, but constitute a promising area of research.

This book's approach to general sensor theory is divided into two parts. Part I deals with the description and composition of sensors and the characterization of the information produced by sensors, whether they be artificial sensors or the sense organs of living beings. The aim here is to define what a sensor is and what methods are used in sensing. The nature of the sensory problem is discussed, the distinction is drawn between sensing and perceiving, and the possible kinds of sensors and sense organs are enumerated. Part II deals with the theoretical and epistemological implications of sensor theory. These include the mature of the sensory object, projections and errors, an information theory model of the sensory process and image analysis. This book is not an engineering manual for the design of artificial sensors, nor is it a discussion of the details of human sense organs or sensation. The aim here is to draw upon these detailed studies and find a theory which encompasses them.
