Group-oriented communications will play a significant role in the next generation of networks as many services, such as pay-per-view media broadcasts and the delivery of network control messages, will rely upon the ability to reliably deliver data simultaneously to a large group of users. As these networks become increasingly pervasive and these multi-user services become increasingly ubiquitous, it will become essential that a complementary suite of security solutions are deployed in order to protect these services from a broad spectrum of security threats that are unique to group communications.
This book aims to fill a growing need in the research community for a reference that describes the state of the art in securing group communications. Network-Aware Security for Group Communications focuses on tailoring the security solution to the underlying network architecture (such as the wireless cellular network or the ad hoc/sensor network), or to the application using the security methods (such as multimedia multicasts).

A momentous debate has been unfolding in China over the last fifteen years, only intermittently in public view, concerning the merits of socialism as a philosophy of social justice and as a program for national development. Just as Deng Xiaoping''s better advertised experiment with market- based reforms has challenged Marxist-Leninist dogma on economic policy, the years since the death of Mao Zedong have seen a profound reexamination of a more basic question: to what extent are the root problems of the system due to Chinese socialism and Marxism generally? Here Yan Sun gathers a remarkable group of primary materials, drawn from an unusual range of sources, to present the most systematic and comprehensive study of post-Mao reappraisal of China''s socialist theory and practice. Rejecting an assumption often made in the West, that Chinese socialist thought has little bearing on politics and policymaking, Sun takes the arguments of the post-Mao era seriously on their own terms. She identifies the major factions in the debate, reveals the interplay among official and unofficial forces, and charts the development of the debate from an initially parochial concern with problems raised by Chinese practice to a grand critique of the theory of socialism itself. She concludes with an enlightening comparison of the reassessments undertaken by Deng Xiaoping with those of Gorbachev, linking them to the divergent outcomes of reform and revolution in their respective countries.

This book shows how different types of motion can be disambiguated into their components in a richer way than that currently possible in computer vision.
Previous research of motion analysis has generally not yet considered the basic nature of higher orders of motion such as acceleration. Hence, this book introduces an approximation of the acceleration field using established optical flow techniques. Further, acceleration is decomposed into radial and tangential based on geometry and propagated as a general motion descriptor; this book shows the capability for differentiating different types of motion both on synthesized data and real image sequences.
Beyond acceleration, the higher orders of motion flow and their continuant parts are investigated for further revealing the chaotic motion fields. Naturally, it is possible to extend this notion further: to detect higher orders of image motion. In this respect, this book shows how jerk and snap can be obtained from image sequences. The derived results on test images and heel strike detection in gait analysis illustrate the ability of higher-order motion, which provide the basis for the following research and applications in the future.
We hope that the publication of this book will bring a new perspective to researchers and graduate students in the field of video analysis in computer vision.
