This book provides a comprehensive overview of data security in cloud storage, ranging from basic paradigms and principles, to typical security issues and practical security solutions. It also illustrates how malicious attackers benefit from the compromised security of outsourced data in cloud storage and how attacks work in real situations, together with the countermeasures used to ensure the security of outsourced data. Furthermore, the book introduces a number of emerging technologies that hold considerable potential – for example, blockchain, trusted execution environment, and indistinguishability obfuscation – and outlines open issues and future research directions in cloud storage security. The topics addressed are important for the academic community, but are also crucial for industry, since cloud storage has become a fundamental component in many applications. The book offers a general introduction for interested readers with a basic modern cryptography background, and a reference guide for researchers and practitioners in the fields of data security and cloud storage. It will also help developers and engineers understand why some current systems are insecure and inefficient, and move them to design and develop improved systems.

Permanent magnet synchronous motors (PMSM) are widely used in industrial manufacturing, transportation and household appliances because of their high power density and excellent performance. In consideration of reducing the size of the control device, cost reduction and system operational reliability, it is necessary to abandon the position sensor and realize the sensorless control of permanent magnet synchronous motor. At present, the magnetic chain observer method is one of the most commonly used and easy to implement algorithms for sensorless control of permanent magnet synchronous motors. However, there is a pure integration link in the magnetic chain observer method, which will bring a certain zero drift due to the sensor error or the dead time. The zero-drift compensation technique based on the chain observation method is investigated in this book. In addition, the maximum torque to current ratio control (MTPA) has the feature of high operating efficiency, so the permanent magnet synchronous motor often uses MTPA control at low speed operation, and often uses weak magnetic control at high speed.

Written by distinguished Chinese academics, this book provides a unique and rare insight into the development of the modern Chinese economy.The authors identify three major factors in the growth of the Chinese economy: economic decentralization and political centralization; the urban-rural divide; and relational society. These are explored in depth via analyses of factors including urban and rural economic development and their political and social foundations, industrial agglomeration, transitions of public services and governmental responsibilities towards them and developmental imbalances and mechanisms. It is illustrated that whilst contemporary China has obviously made great economic strides, a wide variety of problems are accumulating over time. The book concludes that following three decades of high economic growth, China now faces great challenges for sustainable growth, and the institutions of China's economy have reached a critical point. Strategies for dealing with these challenges and requirements for the successful future development of China are thus prescribed.This fascinating book will provide a stimulating read for scholars, students and researchers in the fields of Asian studies, economics and development.Contents: 1.

Southeast Asia is the primary overseas settlement of Fujianese Chinese. The Chinese ancestors from Fujian who made their perilous way to Southeast Asia in ancient times made great contributions to its development. The book describes the historical maritime exchanges between Fujian and Southeast Asia, including politics, economy, culture, personnel exchanges, religious beliefs, and more.
