This book covers and makes four major contributions: 1) analyzing and surveying the pros and cons of current approaches for identifying rumor sources on complex networks; 2) proposing a novel approach to identify rumor sources in time-varying networks; 3) developing a fast approach to identify multiple rumor sources; 4) proposing a community-based method to overcome the scalability issue in this research area. These contributions enable rumor source identification to be applied effectively in real-world networks, and eventually diminish rumor damages, which the authors rigorously illustrate in this book. In the modern world, the ubiquity of networks has made us vulnerable to various risks. For instance, viruses propagate throughout the Internet and infect millions of computers. Misinformation spreads incredibly fast in online social networks, such as Facebook and Twitter. Infectious diseases, such as SARS, H1N1 or Ebola, have spread geographically and killed hundreds of thousands people. In essence, all of these situations can be modeled as a rumor spreading through a network, where the goal is to find the source of the rumor so as to control and prevent network risks. So far, extensive work has been done to develop new approaches to effectively identify rumor sources. However, current approaches still suffer from critical weaknesses. The most serious one is the complex spatiotemporal diffusion process of rumors in time-varying networks, which is the bottleneck of current approaches. The second problem lies in the expensively computational complexity of identifying multiple rumor sources. The third important issue is the huge scale of the underlying networks, which makes it difficult to develop efficient strategies to quickly and accurately identify rumor sources. These weaknesses prevent rumor source identification from being applied in a broader range of real-world applications. This book aims to analyze and address these issues to make rumor source identification more effective and applicable in the real world. The authors propose a novel reverse dissemination strategy to narrow down the scale of suspicious sources, which dramatically promotes the efficiency of their method. The authors then develop a Maximum-likelihood estimator, which can pin point the true source from the suspects with high accuracy. For the scalability issue in rumor source identification, the authors explore sensor techniques and develop a community structure based method. Then the authors take the advantage of the linear correlation between rumor spreading time and infection distance, and develop a fast method to locate the rumor diffusion source. Theoretical analysis proves the efficiency of the proposed method, and the experiment results verify the significant advantages of the proposed method in large-scale networks. This book targets graduate and post-graduate students studying computer science and networking. Researchers and professionals working in network security, propagation models and other related topics, will also be interested in this book.

This monograph presents new theories and methods for fixed-time cooperative control of multi-agent systems. Fundamental concepts of fixed-time stability and stabilization are introduced with insightful understanding. This book presents solutions for several problems of fixed-time cooperative control using systematic design methods. The book compares fixed-time cooperative control with asymptotic cooperative control, demonstrating how the former can achieve better closed-loop performance and disturbance rejection properties. It also discusses the differences from finite-time control, and shows how fixed-time cooperative control can produce the faster rate of convergence and provide an explicit estimate of the settling time independent of initial conditions. This monograph presents multiple applications of fixed-time control schemes, including to distributed optimization of multi-agent systems, making it useful to students, researchers and engineers alike.

This book traces the pedagogical evolution of technical communication in America as it grew out of Engineering English requirements from roughly the turn of the century to 1950. This study examines specific curricular patterns, texts, and writers on the subject of technical communication, while also tracing engineering educational patterns as they emerge from the proceedings of the society for the promotion of engineering education. Unique to the second edition of the book is a new preface by the recent past ATTW series editor, Jimmie Killingsworth, a new introduction by Elizabeth Tebeaux, and an epilogue by Katherine Staples. Writing in a Milieu of Utility concludes that technical writing, as we teach it today, likely found its roots in engineering composition pedagogy, when, at approximately the turn of the century, engineering educators recognized that writing about science and technology not only made sense in an academic milieu that emphasized utility, but that such writing could also contribute to the professional success of engineering students. Existing somewhat tenuously as engineering itself sought academic status, technical communication emerged ultimately as a re-conceptualized composition course, after early to mid twentieth century calls for English and engineering cooperation made traditional composition offerings less relevant. Academic writing on environmental communication proliferated in the 1990's. A few of us had been calling for such work and making initial investigations throughout the 1980's, but the momentum in the field built slowly. Spurred by coverage in the mass media, academic publishers finally caught the wave of interest. In this exciting new volume, the editors demonstrate more fully than ever before how environmental rhetoric and technical communication go hand in hand. The key link that they and their distinguished group of contributors have discovered is the ancient concern of communication scholars with public deliberation. Environmental issues present technical communicators with some of their greatest challenges, above all, how to make the highly specialized and inscrutably difficult technical information generated by environmental scientists and engineers usable in public decision making. The editors encourage us to accept the challenge of contributing to environmentally conscious decision making by integrating technical knowledge and human values. For technical communicators who accept the challenge of working toward solutions by opening access to crucial information and by engaging in critical thinking on ecological issues, the research and theory offered in this volume provide a strong foundation for future practice.
