Digital Signal Processing For High-speed Optical Communication

By: Jianjun Yu,Xinying Li,Junwen Zhang

There is an increasing tendency to integrate optical communication with wireless communication to satisfy continuously emerging (new) data communication demands. Thus, optical-wireless-integrated access networks and transmission systems, as well as LED-based visible light communication are attracting ever increasing research interest. Digital signal processing (DSP) is one new technology for optical transmission. As such this book is designed to pave the way to the better understanding of the deployment of DSP in optical fiber communication systems.Digital Signal Processing for High-Speed Optical Communication covers a wide area of DSP topics in optical communications, and describes state-of-the-art digital signal processing techniques for high-speed optical communication. In this book, numerous advanced digital signal processing techniques aiming at the promotion of the capacity increase and performance improvement of optical or optical-wireless communication systems and networks are presented and explained. Coverage includes new technologies, optical filter with MLSE, and new pre-coding and pre-equalization applicable to single-carrier and multi-carrier, direct-detection and coherent-detection optical commutation systems and networks.

Bond Failure Mechanism of Fully Grouted Rock Bolts

By: Jianhang Chen,Yongliang Li,Junwen Zhang

The purpose of writing this book is to provide the latest research findings in ground control techniques in mining engineering, especially the rock bolting techniques. Since rock bolts are widely used in mining engineering and civil engineering, they are significant in guaranteeing the safety of underground openings. However, instability issues still occur with the rock bolting technique. Therefore, it is valuable to understand the exact load transfer mechanism of rock bolts. This book summarised the recent research work regarding rock bolting conducted by the authors. It is valuable for the readers to fully understand the reinforcing mechanism of fully grouted rock bolts. This book focuses on the bond failure mode of fully grouted rock bolts, which is the most widely encountered failure mode in rock bolting. Different investigation approaches are used in this book, including numerical simulation, analytical modelling and experimental tests. Therefore, this book conducts a comprehensive study to reveal the bond failure process of fully grouted rock bolts. Moreover, it reveals the corresponding bond failure mechanism. Therefore, it helps the reads to fully understand the bond failure mechanism of rock bolting. Moreover, it helps the readers to develop new approaches and methods to prevent failure of the rock bolting system. This is an open access book.

Cross-Cultural Adaptation Experiences of International Scholars in Shanghai

From the Perspective of Organisational Culture

By: Jiexiu Chen,Junwen Zhu

This book examines the cross-cultural adaptation experiences of international scholars working at Shanghai’s top public research universities. On the basis of in-depth interviews, it comprehensively assesses the organisational culture of Chinese universities, recurring problems in international scholars’ cross-cultural adaptation processes, and the coping strategies they employ in response. The book focus on the real lives and working experiences of international scholars in China, and addresses teaching, research, funding applications and organisational politics. Accordingly, it offers a wealth of first-hand information for readers who are interested in the Chinese academic world, especially those scholars/researchers/expatriates currently working in or planning to visit/work in China.
