This book was released on 2012-11-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le contexte économique impose des systèmes toujours plus performants, minimisant coûts d’investissement et de possession. Si les méthodes d’analyse, de synthèse et de gestion présentées dans le premier volume Conception systémique pour la conversion d’énergie électrique 1 participent à l’optimisation des systèmes énergétiques, les techniques traitées dans cet ouvrage proposent d’aller encore plus loin dans la performance. La complexité de systèmes multidisciplinaires à fort degré de couplage augmentant, le processus de conception par optimisation consistant à coupler un modèle à un algorithme d’optimisation au sein d’un environnement logiciel devient dès lors indispensable. Ce volume rassemble les points-clés permettant de représenter efficacement et de façon compacte l’environnement système et les profils de mission, mais également les méthodes, modèles et outils dédiés à l’optimisation. Les approches multiniveaux de conception et l’optimisation technico-économique des réseaux électriques sont particulièrement détaillées.

Book excerpt: This book discusses semiconductor properties, pn-junctions and the physical phenomena for understanding power devices in depth. Working principles of state-of-the-art power diodes, thyristors, MOSFETs and IGBTs are explained in detail, as well as key aspects of semiconductor device production technology. Special peculiarities of devices from the ascending semiconductor materials SiC and GaN are discussed. This book presents significant improvements compared to its first edition. It includes chapters on packaging and reliability. The chapter on semiconductor technology is written in a more in-depth way by considering 2D- and high concentration effects. The chapter on IGBTs is extended by new technologies and evaluation of its potential. An extended theory of cosmic ray failures is presented. The range of certain important physical relationships, doubted in recent papers for use in device simulation, is cleared and substantiated in this second edition.

Download or read book System Dynamics written by Dean C. Karnopp and published by Wiley-Interscience. This book was released on 2000 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard in the field, updated and revised for today's complex mechatronic systems More than ever before, engineers are responsible for the total system design of the products they create. While traditional modeling and simulation methods are useful in the design of static components, they are of little assistance to those charged with designing mechatronic systems comprising a variety of technologies and energy domains. Engineers who design such complex systems need more sophisticated tools to help them think and visualize on a dynamic systems level. This book arms them with one of the most important of those tools-bond graph modeling, a powerful unified graphic modeling language. System Dynamics, Third Edition is the only comprehensive guide to modeling, designing, simulating, and analyzing dynamic systems comprising any number of electrical, mechanical, hydraulic, pneumatic, thermal, and magnetic subsystems. While it has been updated and expanded to include many new illustrations, expanded coverage of computer simulation models, and more detailed information on dynamic system analysis, it has lost none of the qualities that have helped make it the standard text/reference in the field worldwide. With the help of more than 400 illustrations, the authors demonstrate step by step how to: * Model a wide range of mechatronic systems using bond graphs * Experiment with subsystem models to verify or disprove modeling decisions * Extract system characteristics and predict system behaviors * Translate graphical models into complex mathematical simulations * Combine bond graph modeling with state-of-the-art software simulation tools System Dynamics, Third Edition is an indispensable resource for practicing engineers as well as students of mechanical, electrical, aeronautical, and chemical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Download or read book The Political Economy of Populism written by Petar Stankov and published by Routledge. This book was released on 2020-07-21 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Political Economy of Populism explores the interplay between identity, the economy and inequality to explain the dynamics of populist votes since the beginning of the 20th century. The book discusses the political and economic implications of populist governance using data on populist incumbencies and linking it to historical data on the macro economy and democracy. Chapters draw from the most recent political science, economics and other social science literature, as well as historical data, to explain the long-term causes and consequences of populism. Populism emerges and gains traction when political entrepreneurs exploit underlying identity conflicts for political gains. As the distributional consequences of both economic distress and economic growth typically favor the elite over the poor and the lower middle class, economic shocks usually sharpen the underlying identity conflicts between the groups. The book provides evidence of significant differences in the ways fiscal and monetary policies are conducted by incumbent populists in Latin America, Europe and the OECD. The work concludes by suggesting avenues through which a 21st century social consensus can be built, so that our society can avoid repeating the mistakes that led to wars and failed economic experiments in the 20th century. The Political Economy of Populism marks a significant contribution to the study of populism and is suited to students and scholars across the social sciences, including economics, political science and sociology.
