Yang explores the use of crowdsourcing in translation within the Chinese context, focusing on Yeeyan – the largest online translation community in China. As one of the world’s largest markets for language content consumption, China experiences significant demand for translation services. Yeeyan, a pioneer among amateur translation communities in China, offers an autonomous environment where the public collectively determines the content they wish to import from foreign languages. The book conducts a holistic evaluation of crowdsourcing translation using a multidimensional analytical framework, emphasising the interrelations among agents, processes, products, and crowdsourcing environments. Using the Yeeyan community as a case study, the book investigates the motivations behind participation in Yeeyan, the quality of translations produced, the extent to which this quality can be controlled, and how learning occurs through their participation. The analysis includes the two primary types of projects facilitated by Yeeyan – article translation for knowledge-sharing and book translation for commercial publication. Additionally, Yang explores the emerging field of crisis translation - assessing the applications of crowdsourcing in disaster contexts and exploring the ethical implications involved. Drawing on empirically informed results, the book proposes recommendations for the effective design and organisation of crowdsourcing translation projects and elucidates how such initiatives can be optimally utilised in both translation production and translation training endeavours. This book is a valuable contribution to the field of translation studies, offering a detailed examination of crowdsourcing translations and the participatory culture of the Chinese internet.

This book introduces the reliability modelling and optimization of warm standby systems. Warm standby is an attractive redundancy technique, as it consumes less energy than hot standby and switches into the active state faster than cold standby. Since a warm standby component experiences different failure rates in the standby state and active state, the reliability evaluation is challenging and the existing works are only restricted to very special cases. By adapting the decision diagrams, this book proposes the methodology to evaluate the reliability of different types of warm standby systems and studies the reliability optimization. Compared with existing works, the proposed methods allow the system to have an arbitrary number of components and allow the failure time distribution of components to observe arbitrary distributions. From this book, the readers can not only learn how to evaluate and optimize the reliability of warm standby systems but also use the methods to study the reliability of other complex systems.

This book introduces readers to the main theories of phytoremediation and its application to arsenic-contaminated soils in China. The hyperaccumulation theories are introduced, including the use of hyperaccumulators to remove large amounts of arsenic without producing toxic symptoms. The use of synchrotron-based X-ray absorption fine structure radiation to disclose the hyperaccumulation mechanism – a method that makes it possible to detect the elements in plant tissues without destroying the sample – is introduced in detail. This book also includes practical application cases of phytoremediation, which are rarely found in the literature. Allowing readers to gain a thorough understanding of phytoremediation technology, and demonstrating its efficiency in cleaning arsenic-contaminated soils, the book offers a valuable asset for graduate students, lecturers, researchers and engineers in the field of soil remediation.

Large-scale data analytics using machine learning (ML) underpins many modern data-driven applications. ML systems provide means of specifying and executing these ML workloads in an efficient and scalable manner. Data management is at the heart of many ML systems due to data-driven application characteristics, data-centric workload characteristics, and system architectures inspired by classical data management techniques. In this book, we follow this data-centric view of ML systems and aim to provide a comprehensive overview of data management in ML systems for the end-to-end data science or ML lifecycle. We review multiple interconnected lines of work: (1) ML support in database (DB) systems, (2) DB-inspired ML systems, and (3) ML lifecycle systems. Covered topics include: in-database analytics via query generation and user-defined functions, factorized and statistical-relational learning; optimizing compilers for ML workloads; execution strategies and hardware accelerators;data access methods such as compression, partitioning and indexing; resource elasticity and cloud markets; as well as systems for data preparation for ML, model selection, model management, model debugging, and model serving. Given the rapidly evolving field, we strive for a balance between an up-to-date survey of ML systems, an overview of the underlying concepts and techniques, as well as pointers to open research questions. Hence, this book might serve as a starting point for both systems researchers and developers.

Based on the authors’ recent advances, this book focuses on a class of nonlinear systems with mismatched uncertainties/disturbances and discusses their typical control problems. It aims to provide a comprehensive view of the nonrecursive control theory and application guidelines. Various applications on the nonrecursive synthesis of complex nonlinear systems not only greatly simplify the control design process, weaken the system assumptions, and reduce the conservatism of gain selection, but also realize the essential detachment of control law design and Lyapunov function-based stability analysis. Therefore, different from the classical recursive control design methods, it is of significance to study the synthesis of nonlinear systems from the perspective of a new nonrecursive control framework. This book discusses the following typical control problems: theoretical background, homogeneous systems theory review, nonrecursive robust control design, nonrecursive adaptive control design, nonrecursive general dynamic predictive control, disturbance estimation and attenuation, nonrecursive stability analysis, implementation theory and real-life applications to series elastic actuators, DC microgrids, and permanent magnet synchronous motor (PMSM) systems under the proposed nonrecursive synthesis framework. This book will be a great reference for scholars and students in the field of automation and control. It will also be a useful source for control engineers and those working on anti-disturbance control, nonlinear output regulation, nonsmooth control, and other related topics.
