This book explains the hazards associated with electricity in its many forms, including electromagnetic radiation. It describes methods of reducing risks to health and to the environment, giving rules and codes of practice to be followed. Guidelines are also given for the use of electrical equipment in specialised environments (such as locations subject to explosive gases and flammable dusts), the guarding of machine tools and the control of earth currents. Human safety and care for the environment are of increasing concern and the broad scope of the book makes it essential reading for those involved in engineering and technology at all levels; no specialised knowledge of electro-technology is presumed. It is a reference book for personnel responsible for their company's safety policy and for municipal authorities (particularly in Commonwealth countries) and other bodies concerned with technical training, industrial development and planning.

This is the story of the "other" Thomas Edison--not the heroic lone inventor, but Edison the businessman, industrialist, and successful manager of one of the world's largest industrial research laboratories. Tracing his career from his boyhood to his death in 1931, Edison and the Business of Innovation reveals Edison to be an entrepreneur of extraordinary vision. From extensive research in the Edison archives at West Orange, New Jersey, Andre Millard presents new information about Edison the businessman and provides new interpretations of old issues.

One of the main fields of study in the control of dynamical systems has been the effective control of time-varying systems with uncertain parameters and external disturbances. In contrast to stochastic adaptive controllers with identification algorithms, the deterministic control of uncertain time-varying systems has a fixed nonlinear feedback controller, which operates effectively over a specified magnitude range of a class of system variations. If the variations satisfy certain matching conditions, complete insensitivity to system uncertainties can be achieved. The two main approaches are Variables Structure and Lyapunov control. The contents of this book reflect the research output of many authors. The chapters include material of an introductory nature as well as some of the latest research results. Attention has also been focussed upon some of the main areas of application, which include electric motor drives, robotics and flight control systems. The book should prove useful to control designers, theoreticians and graduate students.

In 1961, Moore and Miljanic in collaboration with N. L Kusters developed the current comparator, for which a patent was granted in 1964. Since that time they and their associates have applied this technique toward advancing the art of electrical measurement. The current comparator comprises a special configuration of concentric toroidal magnetic cores and windings which enable the physical realisation of a very precise ampere-turns ratio standard. It provides the basis for the precise measurement of various electrical quantities at both direct and alternating currents using current ratio techniques. Applications include the calibration of instrument transformers, measurement of the losses of high voltage capacitors and inductive reactors, measurement of the short circuit losses of large power transformers, the calibration of power and energy meters, an alternating current impedance bridge, direct current resistance measurements, the calibration of high direct current metering systems and shunts, a seven decade direct current potentiometer, and a 20 bit digital-to-analogue converter. The book presents the basic theory of the current comparator, methods of construction leading to high ratio accuracies, and the operating principles of the various applications.

Recent progress in the design and production of digital signal processing (DSP) devices has provided significant new opportunities to workers in the already extensive field of signal processing. It is now possible to contemplate the use of DSP techniques in cost-sensitive wide bandwidth applications, thereby making more effective use of the large body of available signal processing knowledge. Digital signal processing, long the province of telecommunications is, in both research and applications contexts, of growing importance in fields of medical signal analysis, industrial control (particularly robotics), in the analysis and synthesis of speech and in both audio and video entertainment systems. The growing demand for engineering skills in these areas has led to the writing of this book and the presentation of the material of the book at an lEE-sponsored Vacation School at the University of Leicester. This book is different from others in the field in that it not only presents the fundamentals of DSP ranging from data conversion to z-transforms and spectral analysis, extending this into the areas of digital filtering and control, but also gives significant detail of the new devices themselves and how to use them. In addition to presenting the basic theory and describing the devices and how to design with them, the material is consolidated by extensive use of real examples in specific case studies. The book is directed at readers with first degree level training in engineering, physical sciences or mathematics and with some understanding of electronics, and is appropriate for design engineers in industry, users of DSP devices in scientific research and in all technical development areas associated with the processing of signals for display, storage, transmission or control.

This book covers theoretical methods for the design of continuous time controllers for linear multivariate systems. It is intended for use by those wishing to build on a first course in control systems, either to expand their knowledge as practising engineers or as postgraduate students doing higher degrees in control engineering. Based on material used in graduate courses taught by Professor Balasubramanian at the University of New Brunswick, this book brings together state space and frequency domain design methods for linear multivariable systems. It compares their similarities and highlights the advantages or disadvantages of the various approaches for particular applications. Divided into eleven chapters this book covers in some depth: state space design methods, frequency domain methods for multivariable systems, characteristic locus desiqn methods and stochastic control problems.

The result of a joint effort between representatives of private industry and academia, the publication is divided into sections on elements, alloys, insulators and compound semi-conductors. An index and bibliography are lacking. Numerous simple graphs and charts are provided, in fact most of the boo

The temperature on earth varies over a wide range whereas man can only work comfortably in a quite narrow temperature range that has to be artificially maintained. In addition, many industries have extensive requirements for temperature control. Thus control engineers are called upon very frequently to design temperature control loops. A general knowledge of control engineering is of course useful in designing temperature control loops.However, temperature control has some special features: (i) asymmetries caused by the usually differing mechanisms of heating and cooling (ii) complex nonlinear heat-transfer effects (iii) highly application-dependent measurement problems. The intention of this book is to treat the theory and practice of temperature measurement and control, and important related topics such as energy management and air pollution, at a level suitable for engineering and science undergraduate and postgraduate students, and in a manner designed to make the book valuable to practising engineers. There are no specific prerequisites for the book although a knowledge of elementary control theory could be useful. The philosophy of the book is a compromise between fundamentals and practical guidelines. It is the author's firm belief that it is highly desirable to obtain a good insight into theoretical fundamentals (deeper than can be justified on grounds of immediate utility) before embarking on practical applications. The aim has been to produce a practically oriented text within a firm theoretical outline. The first half of the book is an application oriented survey of temperature measurement techniques and devices. The second half is concerned mainly with temperature control in both simple and complex situations. There are chapters on heat sources, commercially available controllers, temperature control in buildings and energy conservation. The book ends with an appendix that rapidly surveys the underpinning thermodynamic theory.

'To the surprise of some undergraduates, processes do not carry labels marking their variables nor, alas, are they conveniently classified into linear, nonlinear, stochastic, etc., categories. The ability to come to terms with this situation is a prerequisite for anyone proposing to succeed in an industrial environment.' This quotation from Chapter 1 characterises the viewpoint of the book, which is concerned with the application of control theory to real problems in their industrial context. The book is structured around the following beliefs: *(a) Economic aspects must be considered at an early stage of any project. *(b) Simple techniques and ready-made manufacturer's solutions should be applied wherever possible. *(c) More advanced techniques will be received enthusiastically in those applications where they can offer a genuine contribution. *(d) Control systems using distributed microprocessor power will have an impact that is difficult to exaggerate. Control engineers must become familiar with the concepts involved. *(e) Familiarity with a wide range of applications is indispensable in developing an efficient approach in the field of applied control theory. This second edition includes new material and supporting references on: * robotics control * programmable logic controllers * self-tuning controllers * distributed computer control systems * biotechnological control The book should be accessible to a wide variety of engineers. Preferably they should have an elementary knowledge of automatic control theory.

Dieses Buch aus der Feder eines hoch angesehenen Ingenieurs und Verfassers zahlreicher Veroeffentlichungen im Energiesektor ist das umfassendste, grundlichste und aktuellste Nachschlagewerk uber erneuerbare Energien. Die weltweite Energiewirtschaft ist und war schon immer unbestandig und manchmal widerspruchlich, mit erratischen Ausschlagen nach oben und unten. Dies war in der Vergangenheit vor allem darauf zuruckzufuhren, dass der Grossteil unserer Energie aus fossilen Brennstoffen stammt, die eine begrenzt verfugbare Energiequelle darstellen. Es kommt immer wieder vor, dass eine Technologie wie das Fracking einen entscheidenden Wandel herbeifuhrt. Aber tut sie das wirklich? Zoegern wir mit diesen vorubergehenden Preiskorrekturen nicht nur das Unvermeidliche hinaus? Den einzigen wirklichen Wandel bringen die erneuerbaren Energien. Schon seit Jahrzehnten werden erneuerbare Energiequellen ausfindig gemacht, weiterentwickelt und untersucht. Manchmal steht die Windenergie im Vordergrund, manchmal die Solarenergie, und in den letzten rund zehn Jahren hat das Interesse an Biorohstoffen und Biokraftstoffen stark zugenommen. Ausserdem gibt es noch die ?Dauerbrenner?-Technologien der Kernenergie und Geothermie, die beide schon seit sehr langer Zeit genutzt werden. In diesem voellig neuen Werk sind die genannten Themen und Trends in Form einer Enzyklopadie dargestellt, die als schnelles Nachschlagewerk fur Ingenieure, Wissenschaftler und Studierende dient und auch fur Laien geeignet ist, die in der Branche arbeiten oder sich einfach fur das Thema interessieren. Die Beitrage wurden von einem der weltweit bekanntesten und angesehensten Energieingenieure zusammengestellt. Damit ist dieses Buch die umfassendste und aktuellste Enzyklopadie uber erneuerbare Energien, die derzeit erhaltlich ist, und gehoert in jede Bibliothek. Die Encyclopedia of Renewable Energy: * Ist im Stil einer Enzyklopadie geschrieben und befasst sich mit samtlichen Aspekten der erneuerbaren Energien, darunter Windkraft, Solarenergie und vielen anderen Themen * Bietet einen umfassenden UEberblick uber die Branche, von den chemischen Prozessen zur Gewinnung von Biorohstoffen und Biokraftstoffen bis zu den Maschinen und Anlagen, die zur Kraftstoffproduktion und in der Stromerzeugung eingesetzt werden * Enthalt zahlreiche praxistaugliche Beispiele und Designs, die bei der praktischen Anwendung helfen * Ist auf dem aktuellen Stand der Technik und damit ein wichtiges Referenzwerk fur jeden Ingenieur

To serve its purpose, an industrial robot must be harnessed to a manufacturing task, be it welding, assembly, adjustment or the inspection of food products. Complex tasks are likely to require offline programming, both for economy of equipment use and to permit computer simulations for collision avoidance. Vision and other sensory systems are helping to extend the capabilities of robots, while advanced programming techniques are making their use more accessible to the shop floor. The authors have addressed these and many other subjects in a volume which will be of value to industry and to robotic researchers alike.

This book presents developments in analysis and design techniques for control systems. Included are exciting results for feedback systems using complex variable methods, the important concept of robustness in controller design and the increasingly important topic of decentralized control for large scale systems. These and many other contributions illustrate the great activity and rapid progress which has taken place in the subject over the past few years. Only by bringing these contributions together under one cover can the practising engineer in industry and indeed the engineer in university or polytechnic keep fully informed on the 'state of the art' on a number of different fronts. Application of the theoretical developments and practical aspects of the subject are not forgotten; analysis and design of a nuclear boiler and some direct digital control system design procedures are but two topics discussed in the present book. Several of the chapters are followed by problems on the subject matter and worked solutions to most of these problems are given at the end of the book. This aspect will find favour with many readers since such contributions are often a great help in the understanding of the subject matter.

The variety and scope of primary and secondary battery applications in domestic goods and capital equipment for civilian and military uses has steadily grown over the years. Annual global sales of the battery business are exceeding GBP4000 million, encouraging a number of books on individual battery systems. This book is intended to bring together the key features of five electrochemical power sources. Outlining the historical background and basic principles of the direct conversion of electrochemical energy into DC electricity, this book also gives salient details of the manufacturing processes, performances under different conditions of operations and the services for which the batteries are mainly used. This books aims to provide information to graduate electrochemists, engineers working in universities and technical colleges, in Government and other technological institutions, and particularly those engaged in the development of portable power sources and in the design and use of equipment using these devices.

When originally published in the early 1940s, this series was hailed in the New York Times because it emphasizes "method of thought, and not mere acquisition of facts." This volume extends the circuit theory begun in the first volume into the field of magnetic circuits, and covers both heavy-current power and light-current control, measurement, and communication applications of magnetic materials and transformers.

A collection of articles originally intended for use in a graduate course. This collection of papers is the result of a desire to make available reprints of articles on digital signal processing for use in a graduate course offered at MIT. The primary objective was to present reprints in an easily accessible form. At the same time, it appeared that this collection might be useful for a wider audience, and consequently it was decided to reproduce the articles (originally published between 1965 and 1969) in book form. The literature in this area is extensive, as evidenced by the bibliography included at the end of this collection. The articles were selected and the introduction prepared by the editor in collaboration with Bernard Gold and Charles M. Rader. The collection of articles divides roughly into four major categories: z-transform theory and digital filter design, the effects of finite word length, the fast Fourier transform and spectral analysis, and hardware considerations in the implementation of digital filters.
