Smart Metro Station Systems: Data Science and Engineering introduces key technologies in data science and engineering for smart metro station systems. The book consists of three main parts, focusing on the environment, people and energy. Each chapter includes practical applications, along with information on metro traffic flow monitoring and passenger guidance, methods for behavior analysis and trajectory projection, clustering and anomaly detection in crowd hotspots, monitoring and prediction for station humidity, monitoring and spatial prediction for air pollutants, time series feature extraction and analysis of metro load, characteristic and correlation analysis of metro load, and prediction and intelligent ventilation control.

This volume offers a key reference on the emerging area of smart metro stations and will be useful to those working on smart railways, data science, engineering, artificial intelligence and aligned fields.

Speaking Out: Issues and Controversies 各抒己见 is an advanced Chinese language textbook that explores topics such as human nature, moral values, mass consumption, Western influences, and technological innovation. In presenting subjects that reflect major concerns in contemporary China, the book invites students to reflect upon the forces shaping modern Chinese society.

This textbook presents ten lessons in five units entitled "Constancy and Change," "Joy and Sorrow," "Right and Wrong," "Chinese Tradition and Western Influence," and "New and Old." These pairs of opposites conjure up an ever-changing world of ebb and flow, a world that stimulates learners’ imaginations and arouses their enthusiasm for open dialogue and lively discussion.

Concise in language and with lessons in both simplified and traditional characters, the textbook is a valuable aid for university students interested in passing the HSK Level VI or attaining ACTFL advanced-level proficiency. Accompanying audio recordings can be found online at www.routledge.com/9780367902704.

This book gives a detailed introduction to the technical background, feature extraction methods, PHM models and big data embedding methods of the big data theory in PHM for intelligent electromechanical systems. Combination with deep learning and big data, this book explains the hybrid algorithm framework of PHM such as ensemble intelligence and optimized intelligence and introduces PHM models for bearing, IGBT, MOSFET and other components and their big data embedding platform. This book improves the PHM method and theory of electromechanical system under industrial big data and provides reference for the development of intelligent electromechanical equipment and intelligent industrial production in the future.
