On Privacy-Preserving Protocols for Smart Metering Systems
by Fábio Borges de OliveiraThis book presents current research in privacy-preserving protocols for smart grids. It contains several approaches and compares them analytically and by means of simulation. In particular, the book introduces asymmetric DC-Nets, which offer an ideal combination of performance and features in comparison with homomorphic encryption; data anonymization via cryptographic protocols; and data obfuscation by means of noise injection or by means of the installation of storage banks. The author shows that this theory can be leveraged into several application scenarios, and how asymmetric DC-Nets are generalizations of additive homomorphic encryption schemes and abstractions of symmetric DC-Nets. The book provides the reader with an understanding about smart grid scenarios, the privacy problem, and the mathematics and algorithms used to solve it.
On the Logos: A Naïve View on Ordinary Reasoning and Fuzzy Logic (Studies in Fuzziness and Soft Computing #354)
by Enric TrillasThis book offers an inspiring and naïve view on language and reasoning. It presents a new approach to ordinary reasoning that follows the author’s former work on fuzzy logic. Starting from a pragmatic scientific view on meaning as a quantity, and the common sense reasoning from a primitive notion of inference, which is shared by both laypeople and experts, the book shows how this can evolve, through the addition of more and more suppositions, into various formal and specialized modes of precise, imprecise, and approximate reasoning. The logos are intended here as a synonym for rationality, which is usually shown by the processes of questioning, guessing, telling, and computing. Written in a discursive style and without too many technicalities, the book presents a number of reflections on the study of reasoning, together with a new perspective on fuzzy logic and Zadeh’s “computing with words” grounded in both language and reasoning. It also highlights some mathematical developments supporting this view. Lastly, it addresses a series of questions aimed at fostering new discussions and future research into this topic. All in all, this book represents an inspiring read for professors and researchers in computer science, and fuzzy logic in particular, as well as for psychologists, linguists and philosophers.

On the Verge
by Rebecca D. CostaThe author of The Watchman&’s Rattle &“has done it again. On the Verge shows how predictive technologies and science are redefining modern leadership&” (George Mitchell, former Senate Majority Leader). &“There can be no greater advantage than certainty of the future. Not in nature. Not in business. Not in governance.&” So begins Rebecca Costa&’s much-awaited exploration of foresight: &“the crowning achievement of human ambition.&” According to Costa, advances in Big Data, predictive analytics, genomics, artificial intelligence, and other breakthroughs have made it possible to pinpoint future results with mind-blowing accuracy—cracking the door to what Costa calls predaptation: the ability to adapt before the fact. Never before has the information needed to avert danger, get the jump ahead of others, or prepare for the inevitable been so clearly within grasp. Through fascinating real-life examples, Costa reveals how technology has brought nations, businesses, and individuals to the edge of clairvoyance. Yet, our ability to act on foreknowledge often falls short—causing leaders to squander the advantage of preemption. To counteract this failure, Costa illuminates 12 principles of adaptation, and predaptation, used to succeed in fast-moving environments. In the spirit of the best in popular science, On the Verge is a landmark examination of big-picture forces affecting society today. Costa&’s unique sociobiological perspective, combined with her ability to blend humor, breaking science, and insightful personal stories, distinguishes her as one of the most important thought leaders of our time. &“If you have an insatiable curiosity about the impact of innovation on our world ahead and how the future can be manipulated, you will love this book.&”—John Sculley, former CEO of Apple and President of Pepsi-Cola
Once Upon an Algorithm: How Stories Explain Computing (The\mit Press Ser.)
by Martin ErwigHow Hansel and Gretel, Sherlock Holmes, the movie Groundhog Day, Harry Potter, and other familiar stories illustrate the concepts of computing.Picture a computer scientist, staring at a screen and clicking away frantically on a keyboard, hacking into a system, or perhaps developing an app. Now delete that picture. In Once Upon an Algorithm, Martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving. Erwig points out that many daily activities involve problem solving. Getting up in the morning, for example: You get up, take a shower, get dressed, eat breakfast. This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm.Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. Hansel and Gretel, for example, execute an algorithm to get home from the forest. The movie Groundhog Day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter's world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching. Along the way, Erwig also discusses representations and different ways to organize data; “intractable” problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms.This engaging book explains computation accessibly and shows its relevance to daily life. Something to think about next time we execute the algorithm of getting up in the morning.

Open Space: The Global Effort for Open Access to Environmental Satellite Data (Information Policy)
by Mariel BorowitzAn examination of environmental satellite data sharing policies, offering a model of data-sharing policy development, case and practical recommendations for increasing global data sharing.Key to understanding and addressing climate change is continuous and precise monitoring of environmental conditions. Satellites play an important role in collecting climate data, offering comprehensive global coverage that can't be matched by in situ observation. And yet, as Mariel Borowitz shows in this book, much satellite data is not freely available but restricted; this remains true despite the data-sharing advocacy of international organizations and a global open data movement. Borowitz examines policies governing the sharing of environmental satellite data, offering a model of data-sharing policy development and applying it in case studies from the United States, Europe, and Japan—countries responsible for nearly half of the unclassified government Earth observation satellites. Borowitz develops a model that centers on the government agency as the primary actor while taking into account the roles of such outside actors as other government officials and non-governmental actors, as well as the economic, security, and normative attributes of the data itself. The case studies include the U.S. National Aeronautics and Space Administration (NASA) and the U.S. National Oceanographic and Atmospheric Association (NOAA), and the United States Geological Survey (USGS); the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT); and the Japanese Aerospace Exploration Agency (JAXA) and the Japanese Meteorological Agency (JMA). Finally, she considers the policy implications of her findings for the future and provides recommendations on how to increase global sharing of satellite data.
