Power Definitions and the Physical Mechanism of Power Flow

Professor Emanuel uses clear presentation to compare and facilitate understanding of two seminal standards, The IEEE Std. 1459 and The DIN 40110-2:2002-11. Through critical analysis of the most important and recent theories and review of basic concepts, a highly accessible guide to the essence of the standards is presented. Key features: Explains the physical mechanism of energy flow under different conditions: single- and three-phase, sinusoidal and nonsinusoidal, balanced and unbalanced systems Starts at an elementary level and becomes more complex, with six core chapters and six appendices to clarify the mathematical aspects Discusses and recommends power definitions that played a significant historical role in paving the road for the two standards Provides a number of original unsolved problems at the end of each chapter Introduces a new nonactive power; the Randomness power. Power Definitions and the Physical Mechanism of Power Flow is useful for electrical engineers and consultants involved in energy and power quality.

The Sociology of Islam provides an accessible introduction to this emerging field of inquiry, teaching and debate. The study is located at the crucial intersection between a variety of disciplines in the social sciences and the humanities. It discusses the long-term dynamics of Islam as both a religion and as a social, political and cultural force. The volume focuses on ideas of knowledge, power and civility to provide students and readers with analytic and critical thinking frameworks for understanding the complex social facets of Islamic traditions and institutions. The study of the sociology of Islam improves the understanding of Islam as a diverse force that drives a variety of social and political arrangements. Delving into both conceptual questions and historical interpretations, The Sociology of Islam is a transdisciplinary, comparative resource for students, scholars, and policy makers seeking to understand Islam’s complex changes throughout history and its impact on the modern world.

The way people think and act politically is not set in stone. People can and do change the fundamental cultural contours of their political situation. Their political culture does not only restrict imagination and action – it is also a resource for political creativity and invention. In Reinventing Political Culture, this resource is uncovered and explored. Analyzed as a tension between the power of culture and the culture of power, the concept of political culture is reinvented and applied to understanding the practice of people transforming their own political culture in very different circumstances. Three instances of such reinvention are closely examined: one historic, during the twilight of the Soviet empire; one actively in process and actively opposed, ‘the Obama revolution'; and one an apparent distant dream, the power of culture and the culture of power that would avoid ‘the clash of civilizations' in the Middle East. In accessible and engaging prose, Goldfarb clearly and forcefully presents students and scholars of sociology, comparative politics, and cultural studies with an original position on political culture, showing how the political cultures of our times pose not only grave dangers, but also opportunities for creative alternatives.

Resource allocation and power optimization is a new challenge in multimedia services in cellular communication systems. To provide a better end-user experience, the fourth generation (4G) standard Long Term Evolution/Long Term Evolution-Advanced (LTE/LTE-Advanced) has been developed for high-bandwidth mobile access to accommodate today’s data-heavy applications. LTE/LTE-Advanced has adopted discontinuous reception (DRX) to extend the user equipment’s battery lifetime, thereby further supporting various services and large amounts of data transmissions. By introducing the basics of mathematical analysis and performance evaluation of power-saving mechanisms in 3rd generation partnership project (3GPP) LTE and LTE-Advanced networks, the authors of this book aim to describe novel algorithms which could have better performance capabilities than previous methods. Chapter 1 gives the basic theory description of the 3GPP LTE network and 3GPP DRX power saving mechanism, empirical measurements of LTE network traffic and an overview of the basic LTE DRX model in the field of power saving techniques. Chapter 2 provides steps for deriving a 2-state analytical model up to a 4-state DRX model. The third and final chapter summarizes alternative methods for the implementation of LTE DRX. Contents 1. Basic Theory. 2. Analytical Semi-Markov Power-Saving Models. 3. Other Approaches for LTE Power Saving. About the Authors Scott A.
