The acute energy problems facing China today are characterized by their own histories and realities. Some have come about because of China's energy endowment and stage of development, while others have been created by a combination of domestic and global factors. Some are the results of an accumulation of longstanding contradictions, while others are new challenges posed by the new order. There are no «miracle cures» to solve these problems instantly. What is needed is a tireless enquiry, with goals, planning and procedures, guided by a clear energy strategy. With China's increasing dependence on foreign energy sources, and the global energy situation and greenhouse gas issue exerting an increasingly prohibiting effect on China's energy development, energy diplomacy has become an important component of Chinese diplomatic affairs. Based on a «broad energy outlook», this book studies and analyzes China's energy issues and energy strategies from the perspective of electric power. Discusses a variety of issues, including energy transportation and allocation, end-user consumption, markets, early warning and emergency, technical innovation As a leading player in the power and energy area, China’s strategies attracts global attention Proposes the innovative idea of «Macro Energy Perspective» As a key player in China's energy industrial circle, the author's perspective can help global audiences to understand China's energy strategies better Electric Power and Energy in China is ideal for government energy policy makers, engineers, scientists and enterprise managers to understand China’s strategy in electric power and energy. It is also a good reference for energy economics researchers, consultants and university students.

This book presents methods for the design of the main microwave active devices. The first chapter focuses on amplifiers working in the linear mode. The authors present the problems surrounding narrowband and wideband impedance matching, stability, polarization and the noise factor, as well as specific topologies such as the distributed amplifier and the differential amplifier. Chapter 2 concerns the power amplifier operation. Specific aspects on efficiency, impedance matching and class of operation are presented, as well as the main methods of linearization and efficiency improvement. Frequency transposition is the subject of Chapter 3. The author presents the operating principle as well as the different topologies using transistors and diodes. Chapter 4 is dedicated to the operation of fixed frequency and tunable oscillators such as the voltage controlled oscillator (VCO) and the yttrium iron garnet (YIG). The final chapter presents the main control functions, i.e. attenuators, phase shifters and switches.

Explores the nature of academic enterprises, including why they work the way they do and where such enterprises are headed, with the goal of gaining insights into where change can and will happen This book looks at universities from a whole-enterprise perspective. It explores the steady escalation of the costs of higher education and uses a computational economic model of complex academic enterprises. This model includes component models of research, teaching, administration, and brand value. Understanding the relationships among practices, processes, structure, and ecosystem provides the basis for transforming academia, leveraging its strengths and overcoming its limitations. More specifically, this architecture helps the reader understand how various elements of the enterprise system either enable or hinder other elements of the system, all of which are embedded in a complex behavioral and social ecosystem. Each topic is explored in terms of the levels of the architecture at which it primarily functions. Levers of change within each area are discussed, using many experiences of pursuing such issues in a range of academic enterprises. • Provides a new methodology by taking a more systems-oriented approach to education systems as a whole • Shows how various elements of the enterprise system either enable or hinder other elements of the system • Offers alternative strategies for transformation of academic enterprises Universities as Complex Enterprises: How Academia Works, Why It Works These Ways, and Where the University Enterprise Is Headed is a reference for systems scientists and engineers, economists, social scientists, and decision makers. William B. Rouse is the Alexander Crombie Humphreys Chair within the School of Systems & Enterprises and Director of the Center for Complex Systems and Enterprises at Stevens Institute of Technology, Hoboken, New Jersey. He is also Professor Emeritus, and former Chair, of the School of Industrial and Systems Engineering at the Georgia Institute of Technology, Atlanta, Georgia. Rouse has written hundreds of articles and book chapters, and has authored many books, including most recently Modeling and Visualization of Complex Systems and Enterprises (Wiley, 2015).

Linear Circuit Transfer Functions: An introduction to Fast Analytical Techniques teaches readers how to determine transfer functions of linear passive and active circuits by applying Fast Analytical Circuits Techniques. Building on their existing knowledge of classical loop/nodal analysis, the book improves and expands their skills to unveil transfer functions in a swift and efficient manner. Starting with simple examples, the author explains step-by-step how expressing circuits time constants in different configurations leads to writing transfer functions in a compact and insightful way. By learning how to organize numerators and denominators in the fastest possible way, readers will speed-up analysis and predict the frequency response of simple to complex circuits. In some cases, they will be able to derive the final expression by inspection, without writing a line of algebra. Key features: Emphasizes analysis through employing time constant-based methods discussed in other text books but not widely used or explained. Develops current techniques on transfer functions, to fast analytical techniques leading to low-entropy transfer functions immediately exploitable for analysis purposes. Covers calculation techniques pertinent to different fields, electrical, electronics, signal processing etc. Describes how a technique is applied and demonstrates this through real design examples. All Mathcad® files used in examples and problems are freely available for download. An ideal reference for electronics or electrical engineering professionals as well as BSEE and MSEE students, this book will help teach them how to: become skilled in the art of determining transfer function by using less algebra and obtaining results in a more effectual way; gain insight into a circuit’s operation by understanding how time constants rule dynamic responses; apply Fast Analytical Techniques to simple and complicated circuits, passive or active and be more efficient at solving problems.
