The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

Newly arrived in New York in 1882 from Tsarist Russia, the sixteen-year-old Bernard Weinstein discovered an America in which unionism, socialism, and anarchism were very much in the air. He found a home in the tenements of New York and for the next fifty years he devoted his life to the struggles of fellow Jewish workers. The Jewish Unions in America blends memoir and history to chronicle this time. It describes how Weinstein led countless strikes, held the unions together in the face of retaliation from the bosses, investigated sweatshops and factories with the aid of reformers, and faced down schisms by various factions, including Anarchists and Communists. He co-founded the United Hebrew Trades and wrote speeches, articles and books advancing the cause of the labor movement. From the pages of this book emerges a vivid picture of workers’ organizations at the beginning of the twentieth century and a capitalist system that bred exploitation, poverty, and inequality. Although workers’ rights have made great progress in the decades since, Weinstein’s descriptions of workers with jobs pitted against those without, and American workers against workers abroad, still carry echoes today. The Jewish Unions in America is a testament to the struggles of working people a hundred years ago. But it is also a reminder that workers must still battle to live decent lives in the free market. For the first time, Maurice Wolfthal’s readable translation makes Weinstein’s Yiddish text available to English readers. It is essential reading for students and scholars of labor history, Jewish history, and the history of American immigration.

Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.

The social cost of carbon (SC-CO2) is an economic metric intended to provide a comprehensive estimate of the net damages - that is, the monetized value of the net impacts, both negative and positive - from the global climate change that results from a small (1-metric ton) increase in carbon-dioxide (CO2) emissions. Under Executive Orders regarding regulatory impact analysis and as required by a court ruling, the U.S. government has since 2008 used estimates of the SC-CO2 in federal rulemakings to value the costs and benefits associated with changes in CO2 emissions. In 2010, the Interagency Working Group on the Social Cost of Greenhouse Gases (IWG) developed a methodology for estimating the SC-CO2 across a range of assumptions about future socioeconomic and physical earth systems. Valuing Climate Changes examines potential approaches, along with their relative merits and challenges, for a comprehensive update to the current methodology. This publication also recommends near- and longer-term research priorities to ensure that the SC- CO2 estimates reflect the best available science.

The Cold War shaped the world we live in today - its politics, economics, and military affairs. This book shows how the globalization of the Cold War during the last century created the foundations for most of the key conflicts we see today, including the War on Terror. It focuses on how the Third World policies of the two twentieth-century superpowers - the United States and the Soviet Union - gave rise to resentments and resistance that in the end helped topple one superpower and still seriously challenge the other. Ranging from China to Indonesia, Iran, Ethiopia, Angola, Cuba, and Nicaragua, it provides a truly global perspective on the Cold War. And by exploring both the development of interventionist ideologies and the revolutionary movements that confronted interventions, the book links the past with the present in ways that no other major work on the Cold War era has succeeded in doing.

What happens when the bottlenecks that stand between supply and demand in our culture go away and everything becomes available to everyone? "The Long Tail" is a powerful new force in our economy: the rise of the niche. As the cost of reaching consumers drops dramatically, our markets are shifting from a one-size-fits-all model of mass appeal to one of unlimited variety for unique tastes. From supermarket shelves to advertising agencies, the ability to offer vast choice is changing everything, and causing us to rethink where our markets lie and how to get to them. Unlimited selection is revealing truths about what consumers want and how they want to get it, from DVDs at Netflix to songs on iTunes to advertising on Google. However, this is not just a virtue of online marketplaces; it is an example of an entirely new economic model for business, one that is just beginning to show its power. After a century of obsessing over the few products at the head of the demand curve, the new economics of distribution allow us to turn our focus to the many more products in the tail, which collectively can create a new market as big as the one we already know. The Long Tail is really about the economics of abundance. New efficiencies in distribution, manufacturing, and marketing are essentially resetting the definition of what's commercially viable across the board. If the 20th century was about hits, the 21st will be equally about niches.
