This book was released on 2011-11-18 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses reliability and energy efficiency of on-chip networks using cooperative error control. It describes an efficient way to construct an adaptive error control codec capable of tracking noise conditions and adjusting the error correction strength at runtime. Methods are also presented to tackle joint transient and permanent error correction, exploiting the redundant resources already available on-chip. A parallel and flexible network simulator is also introduced, which facilitates examining the impact of various error control methods on network-on-chip performance.

Book excerpt: The most recent publication from the award-winning photographer Pieter Hugo reveals the devastating consequences of toxic waste on one community in Africa. In his previous well-received volumes of photographs, Hugo offers unflinching yet striking portraits of humans, animals, societies, and landscapes that shock and disturb, but also demand our attention. In Permanent Error, he documents a garbage dump in Ghana that has become the repository for discarded computers from around the world. These haunting images document the true cost of a misguided policy-the shipping of millions of tons of obsolete computers to developing countries. The computers are burned to extract valuable metals, effectively turning the site into a toxic wasteland that contaminates air, soil, and groundwater for miles around. These amazing portraits tell a story of a marginal community overwhelmed by poverty, but where human strength and resilience shine through the inhuman conditions Hugo lays bare.
Book Synopsis Dollars Deficits & Trade by : James A. Dorn
Download or read book Dollars Deficits & Trade written by James A. Dorn and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essays in this volume are timelyand provocative. They address the key issues of the changing world economy and consider the implications ofthe erosion ofthe rule oflaw that has occurred both domestically and internationally to an increasing degree over the past halfcentury. The debates over the role of the dollar in the international econ omy, the future shape ofthe international monetary system and the exchange rate regime, the significance ofthe U.S. twin deficits, and the rise of nontariffbarriers to world trade deserve serious attention. Atthe bottom ofthese debates lie differing conceptions ofeconomic policy and the role of government in a free society. Adam Smith's vision ofa limited democracy operating to protect persons and prop erty has been increasinglyreplaced by a vision ofapaternalistic state that is designed to protect special interests at the expense of the larger society. Many of the contributors to this volume point to the lack oflong-run rules designed to promote sound money, fiscal integ rity, and open markets asthe fundamental flawofmodern democratic governments. Although the authors disagree on the specific rules to adopt, the consensus is that a constitutional perspective is needed to ensure astable worldorder. Moreover, since such aperspective must bedeveloped at home before it can spread among nations, the search for optimal international policy coordination is generally seen as misguided. Many ofthe essays in this volume were initially presented at the Cato Institute's Sixth Annual Monetary Conference held in Wash ington, D.C., February 25-26, 1988.
Book Synopsis Distributed Network Systems by : Weijia Jia
Download or read book Distributed Network Systems written by Weijia Jia and published by Springer Science & Business Media. This book was released on 2004-12-15 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both authors have taught the course of “Distributed Systems” for many years in the respective schools. During the teaching, we feel strongly that “Distributed systems” have evolved from traditional “LAN” based distributed systems towards “Internet based” systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of “distributed systems” with orientation to the requirement of the undergraduate level study for today’s distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.

Book Synopsis Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor by : Muhammad Ali Masood Cheema
Download or read book Advanced Direct Thrust Force Control of Linear Permanent Magnet Synchronous Motor written by Muhammad Ali Masood Cheema and published by Springer Nature. This book was released on 2020-02-13 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.

Book Synopsis Permanent Magnet Synchronous and Brushless DC Motor Drives by : Ramu Krishnan
Download or read book Permanent Magnet Synchronous and Brushless DC Motor Drives written by Ramu Krishnan and published by CRC Press. This book was released on 2017-12-19 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters. Addressing that gap with information that has largely been disseminated only in journals and at conferences, Permanent Magnet Synchronous and Brushless DC Motor Drives is a long-awaited comprehensive overview of power electronic converters for permanent magnet synchronous machines and control strategies for variable-speed operation. It introduces machines, power devices, inverters, and control, and addresses modeling, implementation, control strategies, and flux weakening operations, as well as parameter sensitivity, and rotor position sensorless control. Suitable for both industrial and academic audiences, this book also covers the simulation, low cost inverter topologies, and commutation torque ripple of PM brushless DC motor drives. Simulation of the motor drives system is illustrated with MATLAB® codes in the text. This book is divided into three parts—fundamentals of PM synchronous and brushless dc machines, power devices, inverters; PM synchronous motor drives, and brushless dc motor drives. With regard to the power electronics associated with these drive systems, the author: Explores use of the standard three-phase bridge inverter for driving the machine, power factor correction, and inverter control Introduces space vector modulation step by step and contrasts with PWM Details dead time effects in the inverter, and its compensation Discusses new power converter topologies being considered for low-cost drive systems in PM brushless DC motor drives This reference is dedicated exclusively to PM ac machines, with a timely emphasis on control and standard, and low-cost converter topologies. Widely used for teaching at the doctoral level and for industrial audiences both in the U.S. and abroad, it will be a welcome addition to any engineer’s library.
