This book presents several novel constructive methodologies for global stabilization and H-infinity control in switched dynamic systems by using the systems’ structure information. The main features of these new approaches are twofold: i) Novel Lyapunov functions are constructed and new switching strategies are designed to guarantee global finite-time stabilization of the closed-loop switched dynamic systems,while ii) without posing any internal stability requirements on subsystems, the standard H-infinity control problem of the switched dynamic systems is solved by means of dwell-time switching techniques. Systematically presenting constructive methods for analyzing and synthesizing switched systems, the content is of great significance to theoretical research and practical applications involving switched systems alike. The book provides a unified framework for stability analysis, stabilization and H-infinity control of switched systems, making it a valuable resource for researchers and graduate students who want to learn about the state of the art in the analysis and synthesis of switched systems, as well as recent advances in switched linear systems. In addition, it offers a wealth of cutting-edge constructive methods and algorithm designs for researchers who work with switched dynamic systems and graduate students of control theory and control engineering.
Questions about the likelihood of conflict between the United States and China have dominated international policy discussion for years. But the leading theory of power transitions between a declining hegemon and a rising rival is based exclusively on European examples, such as the Peloponnesian War, as chronicled by Thucydides, as well as the rise of Germany under Bismarck and the Anglo-German rivalry of the nineteenth and early twentieth centuries. What lessons does East Asian history offer, for both the power transitions debate and the future of U.S.-China relations? Examining the rise and fall of East Asian powers over 1,500 years, Beyond Power Transitions offers a new perspective on the forces that shape war and peace. Xinru Ma and David C. Kang argue that focusing on the East Asian experience underscores domestic risks and constraints on great powers, not relative rise and decline in international competition. They find that almost every regime transition before the twentieth century was instigated by internal challenges and even the exceptions deviated markedly from the predictions of power transition theory. Instead, East Asia was stable for a remarkably long time despite massive power differences because of common understandings about countries’ relative status. Provocative and incisive, this book challenges prevailing assumptions about the universality of power transition theory and shows why East Asian history has profound implications for international affairs today.

Adaptive filtering still receives attention in engineering as the use of the adaptive filter provides improved performance over the use of a fixed filter under the time-varying and unknown statistics environments. This application evolved communications, signal processing, seismology, mechanical design, and control engineering. The most popular optimization criterion in adaptive filtering is the well-known minimum mean square error (MMSE) criterion, which is, however, only optimal when the signals involved are Gaussian-distributed. Therefore, many "optimal solutions" under MMSE are not optimal. As an extension of the traditional MMSE, the minimum mean p-power error (MMPE) criterion has shown superior performance in many applications of adaptive filtering. This book aims to provide a comprehensive introduction of the MMPE and related adaptive filtering algorithms, which will become an important reference for researchers and practitioners in this application area. The book is geared to senior undergraduates with a basic understanding of linear algebra and statistics, graduate students, or practitioners with experience in adaptive signal processing. Key Features: Provides a systematic description of the MMPE criterion. Many adaptive filtering algorithms under MMPE, including linear and nonlinear filters, will be introduced. Extensive illustrative examples are included to demonstrate the results.

Jihad for Jerusalem explores the agent-structure dynamics in world politics and advances a constructivist theory of choice that explains the role of identity, culture, religion, and other core values in international politics. The struggle for Jerusalem by Iran, Saudi Arabia, Jordan, and Israel is the empirical space where the dynamics between reason and identity, values and strategies, is explored. Jihad for Jerusalem advances a theory of agency in international politics. This theory of agency is based on a reconstituted constructivist paradigm. The theory is tested by an examination of the foreign policy decision making of Iran, Israel, Jordan, and Saudi Arabia towards Israel from 1967-1997. The book uses the foreign policy of these states as cases to test the tension between religion and rationality, between identity and reason, between power and morality, and advances a constructivist theory of choice that explains the importance of the role of culture, religion, identity, and core values in international politics. Anyone interested in international relations theory and the convoluted politics of the Middle East, will find this book intriguing reading.
This book describes the development of human societies over time and identifies the major forces of change that guide history and influence its course. The book argues that the course of history has been driven not by leaders, states, ideas or war but rather by four societal processes, whose actions, reactions and interactions have governed the nature and pace of historical change. These processes are the socio-cultural, political, economic and infomedia processes. Three major conceptions of world history (the cyclical, linear and chaotic) have tried to describe the course of history and explain the dynamics of change. This book reviews these conceptions and concludes that each one of them is only partially able to provide an understanding of the historical dynamics of change. The book incorporates these conceptions into one theory, the locomotive theory of history, that provides a comprehensive explanation of the movement and dynamics of change throughout history. The locomotive theory explains why certain nations have made more progress than others, why some people are getting richer while others remain poor, and why democracy has succeeded in some countries and failed in others. The multiplicity of issues that the book covers makes its analysis and conclusions of particular interest to all people engaged in politics, economics, socioeconomic development and globalization.
