This book focuses on the theory and design methods for guidance, navigation, and control (GNC) in the context of spacecraft rendezvous and docking (RVD). The position and attitude dynamics and kinematics equations for RVD are presented systematically in accordance with several different coordinate systems, including elliptical orbital frame, and recommendations are supplied on which of these equations to use in different phases of RVD. The book subsequently explains the basic principles and relative navigation algorithms of RVD sensors such as GNSS, radar, and camera-type RVD sensors. It also provides guidance algorithms and schemes for different phases of RVD, including the latest research advances in rapid RVD. In turn, the book presents a detailed introduction to intelligent adaptive control and proposes corresponding theoretical approaches to thruster configuration and control allocation for RVD. Emphasis is placed on the design method of active and passive trajectory protection in different phases of RVD, and on the safety design of the RVD mission as a whole. For purposes of verification, the Shenzhou spacecraft’s in-orbit flight mission is introduced as well. All issues addressed are described and explained from basic principles to detailed engineering methods and examples, providing aerospace engineers and students both a basic understanding of, and numerous practical engineering methods for, GNC system design in RVD.

Multimodalities and Chinese Students' L2 Practices: Identity, Community, and Literacy explores the complex relations and interactions among multimodality, positioning, and agency in increasingly digitized, multilingual, and multicultural contexts. Min Wang uses interview narratives, WeChat exchanges, and class observations and field notes of three Chinese international students’ lived experiences of English learning and use in their everyday environments to show that these L2 learners recognized, appreciated, and appropriated affordances of multiple modes and digital tools for their L2 literacies practices. Through these tools and modes, they positioned themselves as confident, able, and competent L2 users, but sometimes also struggling and ambivalent. The practice of meaning-making, remaking, designing, and redesigning demonstrated their agency as L2 learners, which motivated and inspired them to (re)produce and (re)create meanings through discourses for the purpose of presenting desired and anticipated positionings. Positioned as cultural and social beings, these L2 learners presented their self-understandings and self-representations through symbolic and material artifacts, interactions with local and non-local people, and engagement in WeChat discussions and ELI learning. To obtain multimembership, they assumed rights, obligations, and expectations in order to become legitimate community members. In the process of becoming, their agency was promoted, negotiated, or sometimes limited by micro-social structures and ongoing interactions.

This book focuses on the construction of remote islands and reefs in the Maritime Silk Road. Firstly, it analyzes the functions, necessity and difficulties of the construction of remote islands and reefs; then provides corresponding countermeasures. According to the urgent demand of electricity and freshwater, it focus on wave and offshore wind energy evaluation of the important remote islands and reefs of the Maritime Silk Road, providing reference for the choice of location of power plants, daily operation and long term plan of wave/wind power generation. Several important key points are selected in the case study to realize their electricity and freshwater self-sufficiency and thus to improve their viability. This book also presents the marine characteristics (especially hazardous elements) under the demands of island runway construction and marine new energy development, to promote safe and efficient implementation of the remote islands and reefs construction. This bookis one of the series of publications on the 21st Century Maritime Silk Road (shortened as “Maritime Silk Road”). It covers the characteristics of the marine environment and marine new energy, remote islands and reefs construction, climate change, early warning of wave disasters, legal escort, marine environment and energy big data construction, etc. contributing to the safe and efficient construction of the Maritime Silk Road. It aims to improve our knowledge of the ocean, thus to improve the capacity for marine construction, enhance the viability of remote islands and reefs, ease the energy crisis and protect the ecological environment, improve the quality of life of residents along the Maritime Silk Road, and protect the rights, interests of the countries and regions participating in the construction of the Maritime Silk Road. It will be a valuable reference for decision-makers, researchers, and marine engineers working in the related fields.

This book mainly discusses about the alter ego perspectives in literary historiography. This comparative analysis of the major Chinese literary histories in China and in the West brings to light the alter ego perspectives of Stephen Owen in literary historiography. The most interesting part of the book will be the interpretation of new notions and perspectives proposed by Stephen Owen, especially in the newly published The Cambridge History of Chinese Literature (2010). This book gives a detailed overview about the different stages of writing Chinese literary history and the different modes of literary historiography in China and in the West. Two case studies of Chinese poems are made on the notion of discursive communities and the Cultural Tang. Readers will a better understanding about the paradigm of literary historiography and the interrelationships between the different modes of literary historiography and the intellectual history. ?
