Book Synopsis Electrical Machines Diagnosis by : Jean-Claude Trigeassou
Download or read book Electrical Machines Diagnosis written by Jean-Claude Trigeassou and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring and diagnosis of electrical machine faults is a scientific and economic issue which is motivated by objectives for reliability and serviceability in electrical drives. This book provides a survey of the techniques used to detect the faults occurring in electrical drives: electrical, thermal and mechanical faults of the electrical machine, faults of the static converter and faults of the energy storage unit. Diagnosis of faults occurring in electrical drives is an essential part of a global monitoring system used to improve reliability and serviceability. This diagnosis is performed with a large variety of techniques: parameter estimation, state observation, Kalman filtering, spectral analysis, neural networks, fuzzy logic, artificial intelligence, etc. Particular emphasis in this book is put on the modeling of the electrical machine in faulty situations. Electrical Machines Diagnosis presents original results obtained mainly by French researchers in different domains. It will be useful as a guideline for the conception of more robust electrical machines and indeed for engineers who have to monitor and maintain electrical drives. As the monitoring and diagnosis of electrical machines is still an open domain, this book will also be very useful to researchers.
Book Synopsis History of Nonlinear Oscillations Theory in France (1880-1940) by : Jean-Marc Ginoux
Download or read book History of Nonlinear Oscillations Theory in France (1880-1940) written by Jean-Marc Ginoux and published by Springer. This book was released on 2017-04-18 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the French scientific contribution to the mathematical theory of nonlinear oscillations and its development. The work offers a critical examination of sources with a focus on the twentieth century, especially the period between the wars. Readers will see that, contrary to what is often written, France's role has been significant. Important contributions were made through both the work of French scholars from within diverse disciplines (mathematicians, physicists, engineers), and through the geographical crossroads that France provided to scientific communication at the time. This study includes an examination of the period before the First World War which is vital to understanding the work of the later period. By examining literature sources such as periodicals on the topic of electricity from that era, the author has unearthed a very important text by Henri Poincaré, dating from 1908. In this work Poincaré applied the concept of limit cycle (which he had introduced in 1882 through his own works) to study the stability of the oscillations of a device for radio engineering. The “discovery” of this text means that the classical perspective of the historiography of this mathematical theory must be modified. Credit was hitherto attributed to the Russian mathematician Andronov, from correspondence dating to 1929. In the newly discovered Poincaré text there appears to be a strong interaction between science and technology or, more precisely, between mathematical analysis and radio engineering. This feature is one of the main components of the process of developing the theory of nonlinear oscillations. Indeed it is a feature of many of the texts referred to in these chapters, as they trace the significant developments to which France contributed. Scholars in the fields of the history of mathematics and the history of science, and anyone with an interest in the philosophical underpinnings of science will find this a particularly engaging account of scientific discovery and scholarly communication from an era full of exciting developments.

Book Synopsis Nonlinear Observers and Applications by : Gildas Besançon
Download or read book Nonlinear Observers and Applications written by Gildas Besançon and published by Springer. This book was released on 2007-10-11 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this fantastically useful book is to lay out an overview on possible tools for state reconstruction in nonlinear systems. Here, basic observability notions and observer structures are recalled, together with ingredients for advanced designs on this basis. The problem of state reconstruction in dynamical systems, known as observer problem, is crucial for controlling or even merely monitoring processes. For linear systems, the theory has been well established for several years, so this book attempts to tackle the problem for non-linear systems.
Book Synopsis The European Supergrid by : Ana Aguado Cornago
Download or read book The European Supergrid written by Ana Aguado Cornago and published by Claeys & Casteels. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy has always been a potential positive European cooperation and integration factor. Providing zero-carbon power to homes and businesses across the EU will require an open market in electricity, underpinned by both upgraded and new transnational transmission networks. Building this network in time to meet the 2050 challenge will require action now. 'Supergrid' is a European project that will not only integrate the energy markets, but will further contribute to the EU's integration process. Moreover, a European Supergrid will allow Europe to transform its present energy system - still mainly based on fossil fuels - to one that is sustainable, since it will not only be able to optimize all generation (energy mixes) of the Member States, but will integrate all renewable energy sources that Europe wishes to exploit. By doing so, Europe increases its security of supply while diminishing its external dependency, creates new skilled employment opportunities, and gives greater impulse to the new technologies where European companies are currently world leaders. This book will show that the above could be implemented today if there was the political will do so, followed by the implementation of the necessary regulatory instruments. The book will lead readers through the period when the idea of a European Supergrid was just a vision, to the reality of the technological developments that make it possible to have such a transformed energy system in the near future. Europe can afford a transformed energy system. Investing in all these new technologies that can limit global warming to 2 degree C has, of course, a cost, but the cost of doing nothing would be much higher - and not only in terms of money.

Book Synopsis The Theory of Economic Integration (Routledge Revivals) by : Bela Balassa
Download or read book The Theory of Economic Integration (Routledge Revivals) written by Bela Balassa and published by Routledge. This book was released on 2013-05-13 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1962, The Theory of Economic Integration provides an excellent exposition of a complex and far-reaching topic. Professor Balassa has been remarkably successful in covering so much ground with such care and balance, in a treatment which is neither in any way abstruse nor unnecessarily technical. His book will interest economists in Europe by reason of its subject and treatment, but it is also a valuable and reliable textbook for students tackling integration as part of a course of International Economics and for those studying Public Finance. He distinguishes between the various forms of integration (free trade area, customs union, common market, economics union, and total integration). In addition, he applies the theoretical principles to current projects such as the European Common Market and Free Trade Area, and to Latin American integration projects. In offering this theoretical study, the author builds on the conclusions of other writers, but goes beyond this in providing a unifying framework for previous contributions and in exploring questions that in the past received little attention – in particular, the relationship between economic integration and growth (especially the interrelationship between market size and growth, and the implications of various factors for economic growth in an integrated area).

Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.
Book Synopsis On-line Estimation and Adaptive Control of Bioreactors by : G. Bastin
Download or read book On-line Estimation and Adaptive Control of Bioreactors written by G. Bastin and published by Elsevier. This book was released on 2013-10-22 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with monitoring and control of biotechnological processes. Different methods are proposed which are based on the nonlinear structure of the process and do not require any a priori knowledge of the fermentation parameters. The theoretical stability and convergence properties of the proposed algorithms are analysed and their performances are illustrated by simulation results and, in many instances, by real life experiments. The concept of software sensors is introduced; these are algorithms based on the nonlinear model of the process and designed for on-line estimation of the biological variables and/or the fermentation parameters. In order to deal with process nonstationarities and parameter uncertainties, reference is made to adaptive estimation and control techniques.The book is the result of an intensive joint research effort by the authors during the last decade. It is intended as a graduate level text for students of bioengineering as well as a reference text for scientists and engineers involved in the design and optimization of bioprocesses.
