Book excerpt: Les systèmes électrotechniques complexes tels qu'une chaîne électromécanique sont formés de plusieurs éléments de natures différentes (convertisseurs statiques, machines, charge...), qui interagissent de manière étroite. Ce travail a pour but d'étudier ces interactions,en se limitant au cas des perturbations harmoniques, et, de choisir, voire ,d'élaborer les Outils de calcul les mieux adaptes en vue de l'analyse puis de l'optimisation globale des systèmes. Une solution consiste à employer des moyens de simulation et de calcul spectral lourds, tant en durée qu'en volume à stocker, mais elle n'aide guère la compréhension des phénomènes et la validité des résultats est incertaine. C'est pourquoi, il est nécessaire de chercher à simplifier les calculs et/ou les modèles, et à construire des procédures systématiques d'analyse des phénomènes. Une telle approche implique la décomposition modulaire du système en sous-ensembles fonctionnels ou physiques, puis la détermination des interactions à étudier. En conséquence de quoi, un modèle est choisi pour chacun des sous-ensembles et pour son environnement. Enfin l'outil de calcul le mieux adapté à l'application doit être défini. Une méthode d'analyse harmonique capable de prendre en compte les interactions bilatérales entre la source, le convertisseur et la machine est proposée. Elle offre une grande précision et permet de montrer, dans le cas étudié, que les interactions sont faibles et que le modèle global,utilisé peut être simplifié. La méthode est aussi appliquée à un exemple d'étude de compatibilité électromagnétique,et permet alors de réduire sensiblement le volume des 'calculs. Loin d'aborder encore le problème de l'optimisation, cette thèse représente un premier pas vers une approche généralisée de l'analyse globale des systèmes complexes dans un volume de calcul minimisé.

Available in PDF, EPUB and Kindle. Book excerpt: A fully updated textbook on linear systems theory Linear systems theory is the cornerstone of control theory and a well-established discipline that focuses on linear differential equations from the perspective of control and estimation. This updated second edition of Linear Systems Theory covers the subject's key topics in a unique lecture-style format, making the book easy to use for instructors and students. João Hespanha looks at system representation, stability, controllability and state feedback, observability and state estimation, and realization theory. He provides the background for advanced modern control design techniques and feedback linearization and examines advanced foundational topics, such as multivariable poles and zeros and LQG/LQR. The textbook presents only the most essential mathematical derivations and places comments, discussion, and terminology in sidebars so that readers can follow the core material easily and without distraction. Annotated proofs with sidebars explain the techniques of proof construction, including contradiction, contraposition, cycles of implications to prove equivalence, and the difference between necessity and sufficiency. Annotated theoretical developments also use sidebars to discuss relevant commands available in MATLAB, allowing students to understand these tools. This second edition contains a large number of new practice exercises with solutions. Based on typical problems, these exercises guide students to succinct and precise answers, helping to clarify issues and consolidate knowledge. The book's balanced chapters can each be covered in approximately two hours of lecture time, simplifying course planning and student review. Easy-to-use textbook in unique lecture-style format Sidebars explain topics in further detail Annotated proofs and discussions of MATLAB commands Balanced chapters can each be taught in two hours of course lecture New practice exercises with solutions included

Book excerpt: SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the methods of storage commonly used in hybrid systems. After an introductory chapter reviewing the basics of electrochemistry, Chapter 2 is given over to the storage of electricity in the form of hydrogen. Once hydrogen has been made, we have to be able to convert it back into electricity on demand. This can be done with another energy converter: a fuel cell, the subject of Chapter 3. Such a system is unable to deliver significant dynamics in terms of storage and release of electricity and needs to be supplemented with another solution: a detailed study of supercapacitors is provided in Chapter 4.While the storage systems touched upon in the previous three chapters (hydrogen batteries and supercapacitors) both exhibit advantageous characteristics, at present they are still relatively costly. Thus, the days of the electrochemical accumulator by no means appear to be numbered just yet. This will therefore be the topic of Chapter 5. Finally, on the basis of the elements laid down in the previous chapters, Chapter 6 will focus on electrical hybridization of these storage systems, with a view to enhancing the performance (in terms of energy, lifetime, cost, etc.) of the newly formed system. Aimed at an audience of researchers, industrialists, academics, teachers and students, many exercises, along with corrected solutions, are provided throughout the book. Contents 1. Basic Concepts of Electrochemistry used in Electrical Engineering. 2. Water Electrolyzers. 3. Fuel Cells. 4. Electrical Energy Storage by Supercapacitors. 5. Electrochemical Accumulators. 6. Hybrid Electrical System. About the Authors Marie-Cécile Péra is a Full Professor at the University of Franche-Comte in France and Deputy Director of the FEMTO-ST Institute (CNRS).

Available in PDF, EPUB and Kindle. Book excerpt: Of the "big three" components of electrical infrastructure, distribution typically gets the least attention. In fact, a thorough, up-to-date treatment of the subject hasn’t been published in years, yet deregulation and technical changes have increased the need for better information. Filling this void, the Electric Power Distribution Handbook delivers comprehensive, cutting-edge coverage of the electrical aspects of power distribution systems. The first few chapters of this pragmatic guidebook focus on equipment-oriented information and applications such as choosing transformer connections, sizing and placing capacitors, and setting regulators. The middle portion discusses reliability and power quality, while the end tackles lightning protection, grounding, and safety. The Second Edition of this CHOICE Award winner features: 1 new chapter on overhead line performance and 14 fully revised chapters incorporating updates from several EPRI projects New sections on voltage optimization, arc flash, and contact voltage Full-color illustrations throughout, plus fresh bibliographic references, tables, graphs, methods, and statistics Updates on conductor burndown, fault location, reliability programs, tree contacts, automation, and grounding and personnel protection Access to an author-maintained support website, distributionhandbook.com, with problems sets, resources, and online apps An unparalleled source of tips and solutions for improving performance, the Electric Power Distribution Handbook, Second Edition provides power and utility engineers with the technical information and practical tools they need to understand the applied science of distribution.

Book excerpt: Dear participant in the second European Workshop on Microelectronics Education, It is a pleasure to present you the Proceedings of the Second European Workshop on Microelectronics Education and to welcome you at the Workshop. The Organising Committee is very pleased that it has found several key persons, with highly appreciated levels of knowledge and expertise, willing to present Invited Contributions to this Workshop. We have striven for an interesting spread over important areas like the expected demands for educated engineers in the wide field of Microelectronics, and Microsystems, in European industry (and beyond!) and innovations in method and focus of our educational programmes. This is the second European Workshop in this area; the first one was held in Grenoble in France in the spring of 1996. It was the initiative of Georges Kamarinos, Nadine Guillemot and Bernard Courtois to organise this Workshop because they felt that Microelectronics was 'at a turning point' to become the core of the largest industry in the world and that this warranted a serious (re-)consideration of our educational imperatives. It is now two years since and their feeling has become reality: nobody doubts that by the year 2000 the microelecnonics industry will be the largest industrial sector. It is also obvious that because of that and because of the predicted shortfall of educated engineers we must continuously reconsider the quality of our educational approach.
