China is one of the world's largest industrial polluters, and balancing the environmental concerns of citizens, the demands of industry, and the interests of the nation is a complex challenge. Blue Skies over Wuhan uses Hubei Province – particularly its sprawling industrial capital, Wuhan City – as a case study of growing environmental awareness in China in the 1970s and '80s. Yun Liu painstakingly sifts through a wealth of incident records to explore the evolution of environmental protection policy. Reports document repeated sectoral conflicts in this early system of crisis management, when measures to contain industrial emissions largely failed because of inadequate policy implementation. Nonetheless, the attention that Blue Skies over Wuhan gives to newly uncovered evidence reveals a symbiotic relationship between communities and state actors that shaped the trajectory of environmental governance, from an agenda dominated by economic growth priorities to a more mature, state-led approach.

Showcasing local evolutions of Wuhan's education sector from the 1860s to its present, this book examines narratives and changing state-policies for China's education modernization missions.Using a mixed-methods approach, Liu's research provides a fresh lens through which to review China's education transitions via Wuhan's rich tapestry manifested in its education sector. Beginning with Wuhan's modern urbanization as a treaty port from the Second Opium War (1856-1860) to the top-down reforms for industrial and schooling changes led by Zhang Zhidong (1837-1909), the book explores the bottom-up reforms that arose at the alley market of Hanzhenjie at Hankow from the late 1970s in post-Mao China. This reform arguably heralded a set of college reforms, experimented first locally in Wuhan and nationally advocated afterward. Through these events, the author highlights how Wuhan reinforces itself in China's education roadmap via standing at its reforming frontiers.Contributing to interdisciplinary discourses on education development and cultural identity within the context of Communicating China to an increasingly integrated world and a better future, this volume will be of interest to students and researchers interested in Chinese education policy reforms, Chinese educational history and comparative Asian education.

This book is essential and valuable reference for graduate students and academics majored in power electronics, engineers engaged in developing distributed grid-connected inverters, and senior undergraduate students majored in electrical engineering and automation engineering. Soft-switching (SS) technique is an important way to achieve high conversion efficiency and high switching frequency for power converters, which is beneficial to improve power density and reduce volume and cost of power electronics equipment. This book mainly discusses SS technique for transformerless grid-connected inverters (TLIs), and a SS configuration named as “Freewheeling-Resonance-Tank Inverters” is proposed for TLIs fulfilling requirements of switching loss-free, full power factor range, and constant common-mode voltage performance. The detailed theoretical analysis and experimental validations are presented from ZCT and ZVT type topologies, respectively.

By combinatorial semigroups, we mean a general term of concepts, facts and methods which are produced in investigating of algebraic and combinatorial properties, constructions, classifications and interrelations of formal languages and automata, codes, finite and infinite words by using semigroup theory and combinatorial analysis. The main research objects in this field are the elements and subsets of the free semigroups and monoids and many combinatorial properties of these objects, which are closely related to algebraic theory of semigroups.This book first introduces some basic concepts and notations in combinatorial semigroups. Since many contents involving the constructions of (generalized) disjunctive languages and regular languages are closely related to the algebraic theory of codes, some selected topics are introduced in the following chapter, including the method of defining codes by using dependence systems, the maximality and completeness of codes, and the detailed discussion of some special kinds of codes such as convex codes, semaphore codes and solid codes. Then the remaining chapters present the main topics of the book - regular languages, disjunctive languages, and their various kinds of generalizations.This book might be useful to researchers in mathematics who are interested in combinatorial semigroups.
