Available in PDF, EPUB and Kindle. Book excerpt: From the author of the award-winning Moth Smoke comes a perspective on love, prejudice, and the war on terror that has never been seen in North American literature. At a café table in Lahore, a bearded Pakistani man converses with a suspicious, and possibly armed, American stranger. As dusk deepens to night, he begins the tale that has brought them to this fateful meeting. . . Changez is living an immigrant’s dream of America. At the top of his class at Princeton, he is snapped up by Underwood Samson, an elite firm that specializes in the “valuation” of companies ripe for acquisition. He thrives on the energy of New York and the intensity of his work, and his infatuation with regal Erica promises entrée into Manhattan society at the same exalted level once occupied by his own family back in Lahore. For a time, it seems as though nothing will stand in the way of Changez’s meteoric rise to personal and professional success. But in the wake of September 11, he finds his position in his adopted city suddenly overturned, and his budding relationship with Erica eclipsed by the reawakened ghosts of her past. And Changez’s own identity is in seismic shift as well, unearthing allegiances more fundamental than money, power, and perhaps even love. Elegant and compelling, Mohsin Hamid’s second novel is a devastating exploration of our divided and yet ultimately indivisible world. “Excuse me, sir, but may I be of assistance? Ah, I see I have alarmed you. Do not be frightened by my beard: I am a lover of America. I noticed that you were looking for something; more than looking, in fact you seemed to be on a mission, and since I am both a native of this city and a speaker of your language, I thought I might offer you my services as a bridge.” —from The Reluctant Fundamentalist

Book excerpt: How early twentieth-century American policymakers sought to gain control over radiotelegraphy networks in an effort to advance the global position of the United States. In Reluctant Power, Rita Zajácz examines how early twentieth century American policymakers sought to gain control over radiotelegraphy networks in an effort to advance the global position of the United States. Doing so, she develops an analytical framework for understanding the struggle for network control that can be applied not only to American attempts to establish a global radio network in the early twentieth century but also to current US efforts to retain control of the internet. In the late nineteenth century, Britain was seen to control both the high seas and the global cable communication network under the sea. By the turn of the twentieth century, Britain's geopolitical rivals, including the United States, looked to radiotelegraphy that could circumvent Britain's dominance. Zajácz traces policymakers' attempts to grapple with both a new technology—radiotelegraphy—and a new corporate form: the multinational corporation, which managed the network and acted as a crucial intermediary. She argues that both foreign policy and domestic radio legislation were shaped by the desire to harness radiotelegraphy for geopolitical purposes and reveals how communication policy and aspects of the American legal system adjusted to the demands of a rising power. The United States was a reluctant power during the early twentieth century, because policymakers were unsure that companies headquartered in the United States were sufficiently American and doubted that their strategies served the national interest.

Available in PDF, EPUB and Kindle. Book excerpt: The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Available in PDF, EPUB and Kindle. Book excerpt: Switched reluctance motors have steadily increased in commercial importance since their introduction in the early 1980's, while their technology - especially of their electronic control - has made great progress. Their unique characteristics introduce a delicate balance, in which the copper and iron are diminished in quantity, complexity and cost, in favour of a greater reliance on sophistication in the controller. Thus mastery of the control is the key challenge in the application of these machines. This book is intended for engineer's in industry and in the large research community in electrical machines and drives. It introduces the techniques for controlling switched reluctance machines, starting from first principles and building up to the most advanced forms of sensorless control. It covers the recent advances in electronic control and includes aspects of motion control, automation, acoustic noise reduction and energy efficiency. Covers the recent changes in control technology Includes up-to-date equipment and methods Contains applications and case studies

Available in PDF, EPUB and Kindle. Book excerpt: Electric motors are the largest consumer of electric energy and they play a critical role in the growing market for electrification. Due to their simple construction, switched reluctance motors (SRMs) are exceptionally attractive for the industry to respond to the increasing demand for high-efficiency, high-performance, and low-cost electric motors with a more secure supply chain. Switched Reluctance Motor Drives: Fundamentals to Applications is a comprehensive textbook covering the major aspects of switched reluctance motor drives. It provides an overview of the use of electric motors in the industrial, residential, commercial, and transportation sectors. It explains the theory behind the operation of switched reluctance motors and provides models to analyze them. The book extensively concentrates on the fundamentals and applications of SRM design and covers various design details, such as materials, mechanical construction, and controls. Acoustic noise and vibration is the most well-known issue in switched reluctance motors, but this can be reduced significantly through a multidisciplinary approach. These methodologies are explained in two chapters of the book. The first covers the fundamentals of acoustic noise and vibration so readers have the necessary tools to analyze the problems and explains the surface waves, spring-mass models, forcing harmonics, and mode shapes that are utilized in modeling and analyzing acoustic noise and vibration. The second applies these fundamentals to switched reluctance motors and provides examples for determining the sources of any acoustic noise in switched reluctance motors. In the final chapter two SRM designs are presented and proposed as replacements for permanent magnet machines in a residential HVAC application and a hybrid-electric propulsion application. It also shows a high-power and compact converter design for SRM drives. Features: Comprehensive coverage of switched reluctance motor drives from fundamental principles to design, operation, and applications A specific chapter on electric motor usage in industrial, residential, commercial, and transportation applications to address the benefits of switched reluctance machines Two chapters address acoustic noise and vibration in detail Numerous illustrations and practical examples on the design, modeling, and analysis of switched reluctance motor drives Examples of switched reluctance motor and drive design

Book excerpt: It's been many months since Rafel ventured over Barl's Mountains into the unknown, in a desperate bid to seek help for their ravaged land. With his father's Weather Magic exhausted, there seemed no other hope. Now this too has died. Only Deenie believes Rafel still lives, sensing her brother in tortured dreams. She also knows she must try to find him, as only Rafel's talents could heal their land. The prospect terrifies Deenie, yet she sees no other choice. She soon learns of a dangerous new power. Deenie comes to suspect that not only is her brother involved, but that the evil their father destroyed is somehow reborn. And if she can't save Rafel, then through him, Morg's vast power could once again command their world.

Available in PDF, EPUB and Kindle. Book excerpt: With globalization drawing countries closer together, greater international cooperation is essential for peace and stability. The collective arrangement made by governments to manage their trade relations is one of the few successes of globalization. This book assesses the progress of multilateral trade cooperation, exploring the interests at work and the issues raised in successive postwar rounds of negotiations. It traces how the narrow perception of reciprocity has gradually yielded to a broader evaluation of the benefits to the regime as a whole as the major trading nations have mutually reduced trade barriers. Andrew G. Brown demonstrates the increasing importance of rule making and shows the diversity of issues on which negotiations have focused, such as customs procedures, technical standards, subsidies, anti-dumping duties, intellectual property rights, and the treatment of foreign direct investment. Despite the progress, however, the regime has remained vulnerable. The book also analyzes the major sources of strain that have been evident. This is a nontechnical book for those curious about the possibilities for cooperation among states and should be of interest to both the nonspecialist and the specialist. It draws on more than one discipline to interpret the events, lying in the triangle bounded by political science, economics, and history. Andrew G. Brown is a former Director of the General Analysis and Policies Division for the United Nations, New York.

This monograph is intended to remedy that lack & perhaps contribute to a critical edition of some of his major works, especially "Pro ecclesiasticae unitatis defensione (De unitate)," "Apologia ad Carolum Quintum" "De summo pontifice," "De sacramento," a more complete version of "Discorso di pace," &, the most difficult text, "De reformatione ecclesia." In order to grasp the importance of such a project, this volume provides a sketch of Pole's career & the significance of these works.

Available in PDF, EPUB and Kindle. Book excerpt: 'When I was first invited by a new – and handsome – man to the local Yacht Club to see his boat, I happily conjured up alluring pictures of me in an expensive bikini and a great suntan. It didn't occur to me that 'see my boat' might actually mean going out in the thing... Before she knew it, Angela Rice had agreed to a sailing trip on the notorious west coast of Scotland – and to marry her skipper. The voyage did nothing to allay her primal suspicion of anything afloat. But years later, one sunny Boat Show day, she discovered the lifestyle lure of powerboats – so much less daunting than their sailing counterparts. She cajoled her man into crossing to the dark side, with wild promises of becoming competent. And slowly but surely, reluctance gave way to relish, scepticism to skippering, the Solent to the Seine... Originally published as a series in Motorboat & Yachting magazine, and illustrated with wonderful cartoons by David Semple, this is a funny and engaging account of one woman's relationship with the sea, a boat and her husband.

Book excerpt: During the past fifty years few issues in British politics have generated such heated controversy as Britain's approach to European integration. Why has Europe had such an explosive impact on British politics? What impelled British policymakers to embrace a European destiny and why did they take such a cautious approach? These are some of the key issues addressed inThe Reluctant Europeans. This new study draws upon recently available source material providing a clear chronological account and covering events right up to Blair's first year in office and the launch of the Euro.
