Intelligent Systems for Stability Assessment and Control of Smart Power Grids

By: Yan Xu,Yuchen Zhang,Zhao Yang Dong,Rui Zhang

Power systems are evolving towards the Smart Grid paradigm, featured by large-scale integration of renewable energy resources, e.g. wind and solar power, deeper participation of demand side, and enhanced interaction with electric vehicles. While these emerging elements are inherently stochastic in nature, they are creating a challenge to the system’s stability and its control. In this context, conventional analysis tools are becoming less effective, and necessitate the use alternative tools that are able to deal with the high uncertainty and variability in the smart grid. Smart Grid initiatives have facilitated wide-spread deployment of advanced sensing and communication infrastructure, e.g. phasor measurement units at grid level and smart meters at household level, which collect tremendous amount of data in various time and space scales. How to fully utilize the data and extract useful knowledge from them, is of great importance and value to support the advanced stability assessment and control of the smart grid. The intelligent system strategy has been identified as an effective approach to meet the above needs. This book presents the cutting-edge intelligent system techniques and their applications for stability assessment and control of power systems. The major topics covered in this book are: Intelligent system design and algorithms for on-line stability assessment, which aims to use steady-state operating variables to achieve fast stability assessment for credible contingencies. Intelligent system design and algorithms for preventive stability control, which aims at transparent and interpretable decision-making on preventive control actions to manipulate system operating condition against possible contingencies. Intelligent system design and algorithms for real-time stability prediction, which aims to use synchronized measurements to foresee the stability status under an ongoing disturbance. Intelligent system design and algorithms for emergency stability control, which aims at fast decision-making on stability control actions at emergency stage where instability is propagating. Methodologies and algorithms for improving the robustness of intelligent systems against missing-data issues. This book is a reference and guide for researchers, students, and engineers who seek to study and design intelligent systems to resolve stability assessment and control problems in the smart grid age.

A Corpus-based Contrastive Study of the Appraisal Systems in English and Chinese Scientific Research Articles

By: Xu Yuchen,Yan Xuan,Su Rui,Kou Ying

Appraisal is the way language users express their attitude towards things, people, behaviour or ideas. In the last few decades, significant achievements have been made in Appraisal Theory research, yet little attention has been paid to appraisal in scientific texts, especially in relation to the contrast to how it is applied in English and Chinese. This title examines the similarities and differences of Appraisal systems in English and Chinese scientific research articles. Using a self-constructed corpus of scientific research articles, the authors make cross-linguistic comparisons in terms of the quantity and distribution patterns of categories of appraisals. They creatively categorise articles into theoretical scientific research articles and applied studies and discover that for both languages, each genre can have its own favorite mode of distribution for the realization of appraisal systems. In addition, this research helps appraisal theory systems to become more explicit, specific, and more applicable for the analysis of scientific research articles. Students and scholars of applied linguistics, comparative linguistics and corpus linguistics will find this an essential reference.

M8.0 Wenchuan Earthquake

By: Huilin Xing,Xiwei Xu

The M8.0 Wenchuan Earthquake occurred in China on May 12, 2008, killing over 69,000 people and displacing millions from their homes. This was one of the most catastrophic natural disasters on record. This book includes 5 chapters describing the tectonic setting and historical earthquakes around the Chuan-Dian region, the nucleation of the Wenchuan earthquake, occurrence and aftershocks. The field observations of earthquake induced surface fractures and building damage, form a major and special part of this book and include a large number of digital photos with accompanying explanantions.

From Culturalist Nationalism to Conservatism

From Culturalist Nationalism to Conservatism

Origins and Diversification of Conservative Ideas in Republican China

By: Aymeric Xu

What does it mean to be a conservative in Republican China? Challenging the widely held view that Chinese conservatism set out to preserve traditional culture and was mainly a cultural movement, this book proposes a new framework with which to analyze modern Chinese conservatism. It identifies late Qing culturalist nationalism, which incorporates traditional culture into concrete political reforms inspired by modern Western politics, as the origin of conservatism in the Republican era. During the May Fourth period, New Culture activists belittled any attempts to reintegrate traditional culture with modern politics as conservative. What conservatives in Republican China stood for was essentially this late Qing culturalist nationalism that rejected squarely the museumification of traditional culture. Adopting a typological approach in order to distinguish different types of conservatism by differentiating various political implications of traditional culture, this book divides the Chinese conservatism of the Republican era into four typologies: liberal conservatism, antimodern conservatism, philosophical conservatism, and authoritarian conservatism. As such, this book captures – for the first time – how Chinese conservatism was in constant evolution, while also showing how its emblematic figures reacted differently to historical circumstances.

Hazard-causing System and Assessment of Water and Mud Inrush in Tunnel

By: Shucai Li,Zhenhao Xu,Xin Huang,Yuchao Du

This book is composed of eight chapters, introducing the authors’ research and application achievements in the hazard-causing system and disaster evaluation of water and mud inrush in tunnels over the past 10 years. Through a large number of case studies and analysis, and on the basis of existing research, this book puts forward 3 categories and 11 types of tunnel water and mud inrush hazard-causing systems and 4 typical water and mud inrush disaster-forming modes. The authors carefully study the typical cases of tunnel water and mud inrush hazard-causing system, discuss the types of karst water system, structural characteristics, macro-geological identification, engineering identification, karst tunnel route selection principles and evaluation methods in detail, and then develop a dynamic evaluation method of tunnel water and mud inrush construction risk interval and an evaluation method for the resistance body. Ultimately, the authors put forward a systematic identification method of tunnel water and mud inrush disaster, which integrates geological identification, geophysical exploration identification, and drilling identification, and construct a dynamic management and analysis platform for tunnel water and mud inrush cases. This book is used as a reference book for teachers, graduate students, and undergraduates in colleges and universities of civil engineering, transportation, water conservancy and hydropower, mining, geology, etc., and also as a reference for technicians in related engineering fields.

To Build a Free China

A Citizen's Journey

By: Zhiyong Xu

The story of China's rights movement-a struggle for basic human rights and democracy that, despite harsh repression, has endured for more than a decade-unfolds in Xu Zhiyong's compelling personal memoir. In recognition of his work as an activist, lawyer, and founder of the New Citizen Movement, Dr. Xu was named one of Asia Weekly's People of the Year in 2005 and one of the Southern People's Weekly's Top Ten Young Leaders of China in 2006. His efforts have been considerably less well received, however, by the government of the PRC, and he has been arrested numerous times. Dr. Xu has been servin.
