The field of electrical measurement continues to grow, with new techniques developed each year. From the basic thermocouple to cutting-edge virtual instrumentation, it is also becoming an increasingly "digital" endeavor. Books that attempt to capture the state-of-the-art in electrical measurement are quickly outdated. Recognizing the need for a text devoted to the major areas underlying modern electrical measurement, Slawomir Tumanski developed Principles of Electrical Measurement. This text builds a solid foundation in the necessary background concepts and fundamentals needed to develop and use modern electrical instruments. The author first introduces the fundamentals-including main terms and definitions, methods of estimating accuracy and uncertainty, and standards of electrical quantities-and the classical methods of measurement. He then delves into data acquisition, signal conditioning, and signal processing for both analog and digital signals. The final chapter examines computer measuring systems and virtual measurement techniques. By focusing on the aspects that are common to all types of electrical measurement, the book ensures a solid understanding that can be easily applied in practice. Whether used as an introduction to the field or as a reference to the essential concepts, Principles of Electrical Measurement provides the knowledge necessary to develop measurement solutions for any application.

The proceedings of the First Multidisciplinary International Symposium on Positive Systems Theory and Applications (POSTA 2003) held in Rome, Italy, August 28-30, 2003.  Positive Systems are systems in which the relevant variables assume nonnegative values. These systems are quite common in applications where variables represent positive quantities such as populations, goods, money, time, data packets flowing in a network, densities of chemical species, probabilities, etc. The aim of the symposium was to join together researchers working in the different areas related to positive systems such as telecommunications, economy, biomedicine, chemistry and physics in order to provide a multidisciplinary forum where they have the opportunity to exchange ideas and compare results in a unifying framework.

This book deals with LEAs that convert electric energy into controlled mechanical motion of limited travel and LEGs that transform mechanical energy into electric energy. Examples range from loudspeakers and microphones to magnetically levitated material transfer in ultraclean rooms. Much of the literature on linear actuators and generators covers the principles of operation and performance calculations of these devices. Little has been published on their control or on detailed design methodologies. This book presents the first unified treatment of the subject, including the construction, operation, control, and design of LEAs and LEGs. Chapters describe linear induction, permanent-magnet, linear reluctance, switched reluctance, and linear stepper actuators, as well as various types of linear electric generators. The text is amply illustrated with numerous design examples, and will appeal to graduate students and researchers in electrical, mechanical, and design engineering.

State-space methods form the basis of modern control theory. This graduate text is devoted to a description of these methods in the analysis of linear multi-input, multi-output dynamic systems. Following a chapter which sets out the basic concepts and definitions, state equations of finite dimensional systems, and their solution, are discussed in detail. The principles of time-domain and frequency-domain analysis are then presented, as are the properties and applications of the Z-transformation. Separate chapters deal with the controllability, observability, and stability of linear systems. A useful tutorial review of the key results from matrix theory and linear algebra is given in the appendix. The book includes several worked examples, and there are problems at the end of each chapter. It will be of great use to advanced undergraduate and graduate students of electrical or mechanical engineering taking courses in linear systems or control systems.

This volume provides a compilation of recent contributions on feedback and robust control, modeling, estimation and filtering. They were presented on the occasion of the sixtieth birthday of Anders Lindquist, who has delivered fundamental contributions to the fields of systems, signals and control for more than three decades. His contributions include seminal work on the role of splitting subspaces in stochastic realization theory, on the partial realization problem for both deterministic and stochastic systems, on the solution of the rational covariance extension problem and on system identification. Lindquist's research includes the development of fast filtering algorithms, leading to a nonlinear dynamical system which computes spectral factors in its steady state, and which provide an alternate, linear in the dimension of the state space, to computing the Kalman gain from a matrix Riccati equation. He established the separation principle for stochastic function differential equations, including some fundamental work on optimal control for stochastic systems with time lags. His recent work on a complete parameterization of all rational solutions to the Nevanlinna-Pick problem is providing a new approach to robust control design.

This third edition of the principal text on the finite element method for electrical engineers and electronics specialists presents the method in a mathematically undemanding style, accessible to undergraduates who may be encountering it for the first time. Like the earlier editions, it begins by deriving finite elements for the simplest familiar potential fields, and then formulates finite elements for a wide range of applied electromagnetics problems. These include wave propagation, diffusion, and static fields; open-boundary problems and nonlinear materials; axisymmetric, planar and fully three-dimensional geometries; and scalar and vector fields. A wide selection of demonstration programs allows the reader to follow the practical use of the methods. Besides providing all that is needed for the beginning undergraduate student, this textbook is also a valuable reference text for professional engineers and research students.

Get it, read it, and pass it on.

""Most Americans living today never heard Ed Murrow in a live broadcast. This book is for them I want them to know that broadcast journalism was established by someone with the highest standards. Tabloid crime stories, so much a part of the lust for ratings by today's news broadcasters, held no interest for Murrow. He did like Hollywood celebrities, but interviewed them for his entertainment programs; they had no place on his news programs. My book is focused on this life in journalism. I offer it in the hope that more people in and out of the news business will get to know Ed Murrow. Perhaps in time the descent from Murrow's principles can be reversed.""

"Wireless Web Development, Second Edition" provides both a substantial engineering and business background to wireless developers, covering numerous facets of wireless web software geared toward today's mobile platforms and mobile devices. Wireless technologies, including wireless HTML, WAP 2.0, XML, Palm's WCA, and i-mode, are discussed in detail, with individual chapters devoted to each. Author and industry veteran Ray Rischpater places special emphasis on the differences between the Web and the wireless Web, and even between wireless devices themselves, helping the reader to better understand the engineering and interface issues that must be addressed when creating wireless web applications.

By providing the latest information about technologies that have emerged since the first edition was published (i-mode, the growing emphasis on XML in wireless, and WAP 2.0), as well as relegating to historical status those technologies that have failed the test of time (Microsoft Mobile Channels and HDML), Rischpater offers readers a comprehensive and completely updated guide to the latest wireless technologies and development strategies.

Guides readers through the quantitative data analysis process including contextualizing data within a research situation, connecting data to the appropriate statistical tests, and drawing valid conclusions Introduction to Quantitative Data Analysis in the Behavioral and Social Sciences presents a clear and accessible introduction to the basics of quantitative data analysis and focuses on how to use statistical tests as a key tool for analyzing research data. The book presents the entire data analysis process as a cyclical, multiphase process and addresses the processes of exploratory analysis, decision-making for performing parametric or nonparametric analysis, and practical significance determination. In addition, the author details how data analysis is used to reveal the underlying patterns and relationships between the variables and connects those trends to the data s contextual situation. Filling the gap in quantitative data analysis literature, this book teaches the methods and thought processes behind data analysis, rather than how to perform the study itself or how to perform individual statistical tests. With a clear and conversational style, readers are provided with a better understanding of the overall structure and methodology behind performing a data analysis as well as the needed techniques to make informed, meaningful decisions during data analysis. The book features numerous data analysis examples in order to emphasize the decision and thought processes that are best followed, and self-contained sections throughout separate the statistical data analysis from the detailed discussion of the concepts allowing readers to reference a specific section of the book for immediate solutions to problems and/or applications. Introduction to Quantitative Data Analysis in the Behavioral and Social Sciences also features coverage of the following: The overall methodology and research mind-set for how to approach quantitative data analysis and how to use statistics tests as part of research data analysis A comprehensive understanding of the data, its connection to a research situation, and the most appropriate statistical tests for the data Numerous data analysis problems and worked-out examples to illustrate the decision and thought processes that reveal underlying patterns and trends Detailed examples of the main concepts to aid readers in gaining the needed skills to perform a full analysis of research problems A conversational tone to effectively introduce readers to the basics of how to perform data analysis as well as make meaningful decisions during data analysis Introduction to Quantitative Data Analysis in the Behavioral and Social Sciences is an ideal textbook for upper-undergraduate and graduate-level research method courses in the behavioral and social sciences, statistics, and engineering. This book is also an appropriate reference for practitioners who require a review of quantitative research methods. Michael J. Albers, Ph.D., is Professor in the Department of English at East Carolina University. His research interests include information design with a focus on answering real-world questions, the presentation of complex information, and human information interaction. Dr. Albers received his Ph.D. in Technical Communication and Rhetoric from Texas Tech University.

This book is a comprehensive text on the theory of the magnetic recording process. It gives the reader a fundamental, in-depth understanding of all the essential features of the writing and retrieval of information for both high density disk recording and tape recording. The material is timely because magnetic recording technology is currently undergoing rapid advancement in systems capacity and data rate. The competing technologies of longitudinal and perpendicular recording are given parallel treatments throughout this book. A simultaneous treatment of time and frequency response is given to facilitate assessment of signal processing schemes. In addition to covering basic issues, the author discusses key systems questions of non-linearities and overwrite. The emerging technology of magnetoresisitive heads is analysed separately and three chapters are devoted to various aspects of medium noise. This unique book will be valuable as a course text for both senior undergraduates and graduate students. It will also be of value to research and development scientists in the magnetic recording industry. The book includes a large number of homework problems.

This book is designed to give the student a fundamental, in-depth understanding of all the essential features of the magnetic recording process for both high density disk and tape recording. The book provides a thorough grounding in four basic areas of magnetic recording: structure and fields of heads and media, the replay process, the recording process, and medium noise analysis. Besides the fundamental issues, key systems questions of nonlinearities, overwrite, side track phenomena, error rate estimates as well as comparisons of MR and inductive heads will be discussed. The student will be able to use the information presented to design and analyze key experiments for head and medium evaluation as well as for overall system performance decisions. A parallel treatment of time and frequency response will enable the student to evaluate signal processing schemes. The book is intended either for senior-year undergraduates or first-year graduates. It assumes that the reader has had basic introductory electrical engineering or physics courses such as electricity and magnetism and applied mathematics.

The Self-Organising Map (SOM), with its related techniques, is one of the most popular and powerful concepts for unsupervised pattern recognition and data visualisation. Over 3,000 applications have been reported in the open literature, and many commercial projects employ the SOM as the tool for tackling real-world problems.This volume is a complete record of the Third Workshop on Self-Organising Maps, which brought together the leading international researchers and users for an intensive three-day meeting in Lincoln, UK, and so represents the very latest developments in both theory and application of SOMs and associated approaches.Topics covered include:- Pattern recognition and data clustering;- Unsupervised learning using SOMs and other techniques;- Data visualisation;- Commercial and financial applications;- Multi-dimensional signal processing;- Component and system design and condition monitoring.

\While in geometry attempts to square the circle never succeeded, the UML has achieved it: states canbeimplementedasclasses. "{\Wehavemade much progressfrom thetime cloudswere used. " The Uni ed Modeling Language is described as a language for \specifying, - sualizing, constructing, and documenting the artifacts of software systems" and for business modeling (OMG UML V1. x documents). The UML re?ects some of the best experiences in object-oriented modeling, thus it has the potential to become a widely-used standard object-oriented modeling language. As a generally-applicable standard the UML has to be both ?exible (ext- sible, adaptable, modia ble) and precise. Flexibility is needed if the UML is to be used in a variety of application domains. Tailoring of UML syntax and adaptation of UML semantics to system domains is highly desirable. Incor- rating domain-specic concepts into the language will yield modeling languages that more e ectively support system development in these domains. Tailoring may involve determining a subset of the UML that is applicable to the domain, extending or modifying existing language elements, or den ing new language elements. One can envisage UML variants that are tailored to specic domains, for example, UML for real-time systems, multimedia systems, and for intern- based systems. Furthermore, one can also de ne UML variants that determine levels of sophistication in the use of the UML.
