Policy Review of China's Education collects important researches of China's education policies mainly conducted by the academics at East China Normal University (ECNU) in recent years. The book covers various aspects of educational policy studies in China including Regulatory Policies on Private Supplementary Tutoring in China, Accelerated Move for AI Education in China, New Higher Education Policy, non-governmental education, etc. It showcases the significant contributions to scholarship in education policies studies in China.This book is the eighth volume of the WSPC-ECNU Series on China. This series is jointly launched by World Scientific Publishing, the most reputable English academic publisher in Asia, and ECNU, a top University in China with a long history of exchanges with the international academic community.

Audio Coding: Theory and Applications provides succinct coverage of audio coding technologies that are widely used in modern audio coding standards. Delivered from the perspective of an engineer, this book articulates how signal processing is used in the context of audio coding. It presents a detailed treatment of contemporary audio coding technologies and then uses the DRA audio coding standard as a practical example to illustrate how numerous technologies are integrated into a fully-fledged audio coding algorithm. Drawing upon years of practical experience and using numerous examples and illustrations Dr. Yuli You, gives a description of practical audio coding technologies including: * Designing high-performance algorithms that can be readily implemented on fixed-point or integer microprocessors. * How to properly implement an audio decoder on various microprocessors. Transient detection and adaptation of time-frequency resolution of subband filters. * Psychoacoustic models and optimal bit allocation. Audio Coding: Theory and Applications will be a valuable reference book for engineers in the consumer electronics industry, as well as students and researchers in electrical engineering.

This Springer Brief presents recent research results on area coverage for intruder detection from an energy-efficient perspective. These results cover a variety of topics, including environmental surveillance and security monitoring. The authors also provide the background and range of applications for area coverage and elaborate on system models such as the formal definition of area coverage and sensing models. Several chapters focus on energy-efficient intruder detection and intruder trapping under the well-known binary sensing model, along with intruder trapping under the probabilistic sensing model. The brief illustrates efficient algorithms rotate the duty of each sensor to prolong the network lifetime and ensure intruder trapping performance. The brief concludes with future directions of the field. Designed for researchers and professionals working with wireless sensor networks, the brief also provides a wide range of applications which are also valuable for advanced-level students interested in efficiency and networking.
