This book highlights the fundamental theories and prediction methods of radiowave propagation for the design, building, and operation of contemporary satellite systems. The primary objective of this book is to inquire into whether and how it is possible in a democracy to effectively decrease short-sighted policies. Although the commonplace expression “responsibility to future generations” has become firmly established in public and political vocabulary, its operational meaning and practice are not as well understood and have not yet been systematically evaluated. It still has not been successfully translated into viable ethical and theoretical concepts that can guide public policies and action. How can modes of governance and established priorities compatible with the well-being of future generations be created? This book identifies the conditions, and the obstacles, for such future-oriented governance. To meet the needs of diverse satellite applications, the book covers the main factors that affect radiowave propagation, including the clear-air effects, the hydrometeor effects, the ionospheric effects, the earth's surface reflection, and the local environmental effects. To enhance the prediction of radiowave propagation, the book elaborates on the characteristics of radio meteorological and ionospheric environments. It also summarizes research progress on the prediction methods of radio noise and interference coordination for satellite systems. The fade mitigation techniques and the propagation analysis of satellite system design are discussed. Providing a comprehensive summary of common practices and latest advances, the book is intended for researchers and engineers engaged in the study and practice of satellite systems, radio propagation, and its applications.

A power converter is a device used in electrical engineering, power engineering, and the electric power sector to convert electric energy from one form to another, such as converting between AC and DC, changing voltage or frequency, or a combination of these. It is used in a variety of applications, such as industrial drives, power supply, energy generating equipment, consumer goods, electrical vehicles/aeroplanes/ships, smart grids and more.This book will open a door for engineers to design the power converters via the artificial intelligence (AI) method. It begins by reviewing current AI technology in power converters. The book then introduces customized AI algorithms for power converters that take into account the particular characteristics of power converters. The book then presents a set of AI-based design methodologies for power devices, including DC/DC converters, resonant DC/DC converters, bidirectional DC/DC converters, DC/AC inverters, and AC/DC rectifiers. This is the first book to cover all you need to know about using AI to create power converters, including a literature review, algorithm, and circuit design.

This book is devoted to the optimum design of the DCT in a hybrid AC/DC microgrid, which takes into account not only the influence of different inductors/capacitors values, but also numerous design goals (i.e., VCG, efficiency, stability and so on). This book examines the DCT's design problem in detail. It begins by reviewing existing DCTs in, the hybrid AC/DC microgrid and their design problems. Following that, this book proposes a family of DCT optimization design approaches to ensure that the designed DCT has good power transmission and voltage regulation ability in the hybrid AC/DC microgrid, even when the actual inductors/capacitors values fluctuate with practical power and temperature. Following that, this book provides a family of multi-objective optimization design methodologies for the DCT to guarantee that it concurrently achieves the requirements of VCG, efficiency, and system stability. This book also covers how to control the DCT in a hybrid AC/DC microgrid optimally and generically.

This book introduces a family of large-signal stability-based control methods for different power inverters (grid-connected inverter, standalone inverter, single-phase inverter, and three-phase inverter) in practical applications. Power inverters have stability issues, which include the inverter's own instability as well as the inverter's instability in relation to the other power electronic devices in the system (i.e., weak grid and the EMI filter). Most of the stability analyses and solutions are based on small-signal stability technology. Unfortunately, in actuality, the majority of practical instability concerns in power inverter systems are large-signal stability problems, which, when compared to small-signal stability problems, can cause substantial damage to electrical equipment. As a result, researchers must conduct a comprehensive investigation of the large-signal stability challenge and solutions for power inverters. This book can be used as a reference for researchers, power inverters manufacturers, and end-users. As a result, the book will not become obsolete in the near future, regardless of technology advancements.

The story of globalization in the nineteenth and early twentieth centuries as experienced by ordinary people in the Chinese river town of Zhenjiang.Fear swept Zhenjiang as British soldiers gathered outside the city walls in the summer of 1842. Already suspicious of foreigners, locals had also heard of the suffering the British inflicted two months earlier, in Zhapu. A wave of suicides and mercy killings ensued: rather than leave their families to the invaders, hundreds of women killed themselves and their children or died at the hands of male family members. British observers decried an “Asian culture” of ritual suicide. In reality, the event was sui generis—a tragic result of colliding local and global forces in nineteenth-century China.Xin Zhang’s groundbreaking history examines the intense negotiations between local societies and global changes that created modern China. In the nineteenth and early twentieth centuries, world-historic political, economic, and technological developments transformed the textures of everyday life in places like Zhenjiang, a midsize river town in China’s prosperous Lower Yangzi region. Drawing on rare primary sources, including handwritten diaries and other personal writings, Zhang offers a ground-level view of globalization in the city. We see civilians coping with the traumatic international encounters of the Opium War; Zhenjiang brokers bankrolling Shanghai’s ascendance as a cosmopolitan commercial hub; and merchants shipping goods to market, for the first time, on steamships.Far from passive recipients, the Chinese leveraged, resisted, and made change for themselves. Indeed, The Global in the Local argues that globalization is inevitably refracted through local particularities.

The book summarizes the emerging topic about the effects of SMF on biological samples ranging from single molecules, subcellular compartments, and cells to whole organisms, as well as the potential application of SMF in clinical treatment of cancer and other diseases. With the development and growing popularity of modern appliances, including MRI in the hospitals, the potential impact of magnetic fields on human health is invoking increasing concerns. At the same time, SMF has been used in the clinical treatment of tumors and other diseases for decades. However, there are still some reservations and uncertainties about these treatments, which are largely due to the differential biological effects reported in the literature. These experimental inconsistencies are mainly caused by variations such as different magnetic field types, intensities, treatment time as well as biological samples examined. This volume will help clarify some dilemmas in this field and encourage further investigations in order to achieve a better understanding of the biological effects of SMF, aiming for a rational application of SMF in clinical therapy in the near future. The book is useful for scientists doctors, and students who are interested in magnetic fields and life sciences.

Proteins act as macromolecular machinery that mediate many diverse biological processes - the molecular mechanisms of this machinery has fascinated biologists for decades. Analysis of the kinetic and thermodynamic features of these mechanisms could reveal unprecedented aspects of how the machinery function and will eventually lead to a novel understanding of various biological processes. This dissertation comprehensively demonstrates how two universally conserved guanosine triphosphatases in the signal recognition particle and its membrane receptor maintain the efficiency and fidelity of the co-translational protein targeting process essential to all cells. A series of quantitative experiments reveal that the highly ordered and coordinated conformational states of the machinery are the key to their regulatory function. This dissertation also offers a mechanistic view of another fascinating system in which multistate protein machinery closely control critical biological processes.Written while completing graduate work at California Institute of Technology.

The sources and nature of China's transformation from a traditional to modern society - accelerated in the early twentieth century by the downfall of the Qing dynasty, the advent of foreign technology and increasing commercialization - are critical issues for the study of modern China. In this book, Xin Zhang uses the case of local elites and the power structure of Henan province in north-central China to demonstrate how local politics first transformed local society, challenged the state and eventually influenced change across China. Rather than focusing separately on elite mobility, social mobilization or state-making, Zhang observes changes in all three categories as interrelated aspects of a single, self-generating phenomenon of social change. Zhang's application of social science theory and rich, original, empirical data, sheds light on the sources of China's modernization, political and social identity, and the shifting relationship between the state and local elites.
