Lu Jiang goes to the United States to study in 1989 when her marriage breaks up. On the airplane, she happens to sit by a sad Chinese writer, also a political exile. Their story starts to develop and ends a decade later when he dies in her arms. In New York, she meets a group of Chinese students who become her lifelong friends. Two years later, Lu Jiang returns to China to teach and to bring up her son. When routing through Europe, Lu Jiang meets an ambitious man in London whose aspiration is to build a strong and prosperous China. Their friendship evolves into love after they meet again in China. Yet their relationship brings them more pain than they can possibly foresee. Years later, many of her friends return to China, too, and become pillars of society. This book tells the life stories of Lu Jiang and her friends over a span of thirty plus years. Tasting all flavors that life has to offer, they age as they witness in pride the advancement of their motherland, which their generation helps to bring about.
Chosen by Louise Glück for the Max Ritvo Poetry Prize, this engrossing debut interrogates history, identity, and the power of poetry to elucidate both. Motherlands opens with a child drawn early to poetry. “In summer I write. Two lines at a time, two vying souls / running up the wall.” The collection follows this speaker-poet through a childhood in post-Maoist China and an eventual move to the United States, laying bare cultural and linguistic tensions in both historical and modern settings. He cites Chinese laborers toiling in American factories—an echo of the brutalities endured by those who constructed the Transatlantic Railroad—and speaks to anxieties around belonging, assimilation, and identity. “If I forget one character a day,” he writes. “I will have forgotten Chinese / by the end of 2042.” In these attentive, imaginative poems, Weijia Pan questions the artist’s duty—his duty—as a chronicler of truth, especially through issues of displacement and global injustice. What can the poet do but observe? And yet, in unpacking ancestral traumas connected to Maoist China and modern-day bigotry exacerbated by the COVID-19 pandemic, he still finds himself turning to art as a way to understand both the self and the world at large. Through elegant juxtapositions, Pan crafts an emotional world that is at once regional and universal—Li Bai and Du Fu sit alongside Glenn Gould and Sviatoslav Richter, pepper used to bless new roads is repurposed in the mace used against protesters, two languages compete on a single tongue. Lyrical and visionary, this collection embodies poetry’s capacity to ground us, teach us, and change us.
This book reports on a comprehensive study addressing the dynamic responses of hydropower plants under diverse conditions and disturbances, and analyzes their stability and oscillations. Multiple models based on eight existing hydropower plants in Sweden and China were developed and used for simulations and theoretical analysis with various degrees of complexity and for different purposes, and compared with on-site measurements for validations. The book offers important insights into the understanding of the hydraulic, mechanical and electrical coupling mechanisms, up to market conditions and incentives. It recommends control strategies for a more stable and efficient operation of hydropower plants.
Learning Chinese Language and Culture is an intermediate level textbook, which was intended to be used throughout the entire school year and designed mainly for students who have completed introductory courses of Chinese as a foreign language. Written in English, Traditional and Simplified Chinese, this book illustrates Chinese language knowledge and introduces Chinese culture in twentytwo lessons, covering a variety of cultural content, including customs and manners, holidays and festivals, poems and idioms, calligraphy and couplets, myths and legends, feng shui and superstitions, and historical relics and sceneries and many others. In every lesson, the authors have strived to maintain a clear topic and a coherent structure. They have also endeavored to keep the contents lively and achieve a fluent writing style while closely controlling the structure and grammar of every lesson.
Using a designed vector field to guide robots to follow a given geometric desired path has found a range of practical applications, such as underwater pipeline inspection, warehouse navigation, and highway traffic monitoring. It is thus in great need to build a rigorous theory to guide practical implementations with formal guarantees. It is even so when multiple robots are required to follow predefined desired paths or maneuver on surfaces and coordinate their motions to efficiently accomplish repetitive and laborious tasks. The book introduces guiding vector fields on Euclidean spaces and Riemannian manifolds for single-robot and multi-robot path-following and motion coordination, provides rigorous theoretical guarantees of vector field guided motion control of robotic systems, and elaborates on the practical implementation of the proposed algorithms on mobile wheeled robots and fixed-wing aircraft. It provides guidelines for the robust, reliable, and safe practical implementations for robotic tasks, including path-following navigation, obstacle-avoidance, and multi-robot motion coordination. In particular, the book reveals fundamental theoretic underpinnings of guiding vector fields and applies to addressing various robot motion control problems. Notably, it answers many crucial and challenging questions such as: · How to generate a general guiding vector field on any n-dimensional Riemannian manifold for robot motion control tasks? · Do singular points always exist in a general guiding vector field? · How to generate a guiding vector field that is free of singular points? · How to design control algorithms based on guiding vector fields for different robot motion control tasks including path-following, obstacle-avoidance, and multi-robot distributed motion coordination? Answering these questions has led to the discovery of fundamental assumptions, a “topological surgery” to create a singularity-free guiding vector field, a robot navigation algorithm with the global convergence property, a provably safe collision-avoidance algorithm and an effective distributed motion control algorithm, etc
Both authors have taught the course of “Distributed Systems” for many years in the respective schools. During the teaching, we feel strongly that “Distributed systems” have evolved from traditional “LAN” based distributed systems towards “Internet based” systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of “distributed systems” with orientation to the requirement of the undergraduate level study for today’s distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.
Second-Generation High-Temperature Superconducting Coils and Their Applications for Energy Storage addresses the practical electric power applications of high-temperature superconductors. It validates the concept of a prototype energy storage system using newly available 2G HTS conductors by investigating the process of building a complete system from the initial design to the final experiment. It begins with a clear introduction of the related background and then presents a comprehensive design of a superconducting energy storage system that can store maximum energy using a limited length of superconductors. The author has created a modeling environment for analysis of the system and also presents experimental results that are highly consistent with his theoretical calculations.
This paper builds a novel database on the effects of macroprudential policy drawing from 58 empirical studies, comprising over 6,000 results on a wide range of instruments and outcome variables. It encompasses information on statistical significance, standardized magnitudes, and other characteristics of the estimates. Using meta-analysis techniques, the paper estimates average effects to find i) statistically significant effects on credit, but with considerable heterogeneity across instruments; ii) weaker and more imprecise effects on house prices; iii) quantitatively stronger effects in emerging markets and among studies using micro-level data; and iii) statistically significant evidence of leakages and spillovers. Other findings include relatively stronger impacts for tightening than loosening actions and negative effects on economic activity in the near term.
This reader is comprised of 22 lessons presented in authentic Chinese which offer an introduction to Chinese culture, its history, language, folklore, religion, and its contemporary and historical social practices.
