Rainbows End
by Vernor VingeFour time Hugo Award winner Vernor Vinge has taken readers to the depths of space and into the far future in his bestselling novels A Fire Upon the Deep and A Deepness in the Sky. Now, he has written a science-fiction thriller set in a place and time as exciting and strange as any far-future world: San Diego, California, 2025.<P><P> Robert Gu is a recovering Alzheimer's patient. The world that he remembers was much as we know it today. Now, as he regains his faculties through a cure developed during the years of his near-fatal decline, he discovers that the world has changed and so has his place in it. He was a world-renowned poet. Now he is seventy-five years old, though by a medical miracle he looks much younger, and he's starting over, for the first time unsure of his poetic gifts. Living with his son's family, he has no choice but to learn how to cope with a new information age in which the virtual and the real are a seamless continuum, layers of reality built on digital views seen by a single person or millions, depending on your choice. But the consensus reality of the digital world is available only if, like his thirteen-year-old granddaughter Miri, you know how to wear your wireless access -- through nodes designed into smart clothes -- and to see the digital context -- through smart contact lenses.<P> With knowledge comes risk. When Robert begins to re-train at Fairmont High, learning with other older people what is second nature to Miri and other teens at school, he unwittingly becomes part of a wide-ranging conspiracy to use technology as a tool for world domination.<P> In a world where every computer chip has Homeland Security built-in, this conspiracy is something that baffles even the most sophisticated security analysts, including Robert's son and daughter-in law, two top people in the U.S. military. And even Miri, in her attempts to protect her grandfather, may be entangled in the plot.<P> As Robert becomes more deeply involved in conspiracy, he is shocked to learn of a radical change planned for the UCSD Geisel Library; all the books there, and worldwide, would cease to physically exist. He and his fellow re-trainees feel compelled to join protests against the change. With forces around the world converging on San Diego, both the conspiracy and the protest climax in a spectacular moment as unique and satisfying as it is unexpected. This is science fiction at its very best, by a master storyteller at his peak.<P> Hugo Award winner.
Raising a Screen-Smart Kid: Embrace the Good and Avoid the Bad in the Digital Age
by Julianna MinerFor parents who didn't grow up with smartphones but can't let go of them now, expert advice on raising kids in our constantly connected worldMost kids get their first smartphone at the same time that they're experiencing major developmental changes.

Raising the Stakes: E-Sports and the Professionalization of Computer Gaming
by T. L. TaylorHow a form of play becomes a sport: players, agents, referees, leagues, tournaments, sponsorships, and spectators, and the culture of professional computer game play.Competitive video and computer game play is nothing new: the documentary King of Kong memorably portrays a Donkey Kong player's attempts to achieve the all-time highest score; the television show Starcade (1982–1984) featured competitions among arcade game players; and first-person shooter games of the 1990s became multiplayer through network play. A new development in the world of digital gaming, however, is the emergence of professional computer game play, complete with star players, team owners, tournaments, sponsorships, and spectators. In Raising the Stakes, T. L. Taylor explores the emerging scene of professional computer gaming and the accompanying efforts to make a sport out of this form of play.In the course of her explorations, Taylor travels to tournaments, including the World Cyber Games Grand Finals (which considers itself the computer gaming equivalent of the Olympics), and interviews participants from players to broadcasters. She examines pro-gaming, with its highly paid players, play-by-play broadcasts, and mass audience; discusses whether or not e-sports should even be considered sports; traces the player's path from amateur to professional (and how a hobby becomes work); and describes the importance of leagues, teams, owners, organizers, referees, sponsors, and fans in shaping the structure and culture of pro-gaming.Taylor connects professional computer gaming to broader issues: our notions of play, work, and sport; the nature of spectatorship; the influence of money on sports. And she examines the ongoing struggle over the gendered construction of play through the lens of male-dominated pro-gaming. Ultimately, the evolution of professional computer gaming illuminates the contemporary struggle to convert playful passions into serious play.

The examples are meant to be implemented, experimented with and improved/adapted by the reader.
Random Sets and Random Fuzzy Sets as Ill-Perceived Random Variables
by Didier Dubois Inés Couso Luciano SánchezThis short book provides a unified view of the history and theory of random sets and fuzzy random variables, with special emphasis on its use for representing higher-order non-statistical uncertainty about statistical experiments. The authors lay bare the existence of two streams of works using the same mathematical ground, but differing form their use of sets, according to whether they represent objects of interest naturally taking the form of sets, or imprecise knowledge about such objects. Random (fuzzy) sets can be used in many fields ranging from mathematical morphology, economics, artificial intelligence, information processing and statistics per se, especially in areas where the outcomes of random experiments cannot be observed with full precision. This book also emphasizes the link between random sets and fuzzy sets with some techniques related to the theory of imprecise probabilities. This small book is intended for graduate and doctoral students in mathematics or engineering, but also provides an introduction for other researchers interested in this area. It is written from a theoretical perspective. However, rather than offering a comprehensive formal view of random (fuzzy) sets in this context, it aims to provide a discussion of the meaning of the proposed formal constructions based on many concrete examples and exercises. This book should enable the reader to understand the usefulness of representing and reasoning with incomplete information in statistical tasks. Each chapter ends with a list of exercises.
Random Walks and Diffusions on Graphs and Databases
by Dimitri Volchenkov Philipp BlanchardMost networks and databases that humans have to deal with contain large, albeit finite number of units. Their structure, for maintaining functional consistency of the components, is essentially not random and calls for a precise quantitative description of relations between nodes (or data units) and all network components. This book is an introduction, for both graduate students and newcomers to the field, to the theory of graphs and random walks on such graphs. The methods based on random walks and diffusions for exploring the structure of finite connected graphs and databases are reviewed (Markov chain analysis). This provides the necessary basis for consistently discussing a number of applications such diverse as electric resistance networks, estimation of land prices, urban planning, linguistic databases, music, and gene expression regulatory networks.

A Rapid Introduction to Adaptive Filtering (SpringerBriefs in Electrical and Computer Engineering)
by Hernan Rey Leonardo Rey VegaIn this book, the authors provide insights into the basics of adaptive filtering, which are particularly useful for students taking their first steps into this field. They start by studying the problem of minimum mean-square-error filtering, i.e., Wiener filtering. Then, they analyze iterative methods for solving the optimization problem, e.g., the Method of Steepest Descent. By proposing stochastic approximations, several basic adaptive algorithms are derived, including Least Mean Squares (LMS), Normalized Least Mean Squares (NLMS) and Sign-error algorithms. The authors provide a general framework to study the stability and steady-state performance of these algorithms. The affine Projection Algorithm (APA) which provides faster convergence at the expense of computational complexity (although fast implementations can be used) is also presented. In addition, the Least Squares (LS) method and its recursive version (RLS), including fast implementations are discussed. The book closes with the discussion of several topics of interest in the adaptive filtering field.
