The Forgetting Machine
by Pete HautmanPeople all over Flinkwater are losing their memories--and it's up to Ginger to figure out what's going on--in this sequel to the "quirky, dryly funny" (Booklist) The Flinkwater Factor from National Book Award-winning author Pete Hautman.Absentmindedness in Flinkwater, a town overflowing with eccentric scientists and engineers, is nothing new. Recently, however, the number of confused, forgetful citizens has been increasing, and no one seems to know why. Ginger Crump figures it's none of her business. She has her own problems. Like the strange cat that's been following her around--a cat that seems to be able to read. And the report for school due Monday. And the fact that every digital book in Flinkwater has been vandalized by a fanatical censor, forcing Ginger to the embarrassingly retro alternative of reading books printed on dead trees. But when Ginger's true love and future husband Billy Bates completely forgets who she is, things suddenly get serious, and Ginger swings into action.
Forging China's Military Might: A New Framework for Assessing Innovation
by Tai Ming Cheung“His collection of nine essays offers a comprehensive and insightful assessment of the Chinese defense science and technology (S&T).” —Pacific AffairsAmong the most important issues in international security today are the nature and the global implications of China’s emergence as a world-class defense technology power. Since the beginning of the twenty-first century, the Chinese defense industry has reinvented itself by emphasizing technological innovation and technology. This reinvention and its potential effects, both positive and negative, are attracting global scrutiny. Drawing insights from a range of disciplines, including history, social science, business, and strategic studies, Tai Ming Cheung and the contributors to Forging China’s Military Might develop an analytical framework to evaluate the nature, dimensions, and spectrum of Chinese innovation in the military and broader defense spheres.Forging China’s Military Might provides an overview of the current state of the Chinese defense industry and then focuses on subjects critical to understanding short- and long-term developments, including the relationship among defense contractors, regulators, and end-users; civil-military integration; China’s defense innovation system; and China’s place in the global defense economy. Case studies look in detail at the Chinese space and missile industry.“Constitutes high-quality, cutting-edge research on China’s defense industries. It should enjoy broad appeal—among academics, policy makers, security analysts, and business people in countries around the world.” —Andrew Scobell, RAND Corporation“Forging China’s Military Might belongs in any political science shelf interested in China’s issues and international security and considers the nature of China’s emergence as a world power.” —Midwest Book Review
Forging Trust Communities: How Technology Changes Politics
by Irene S. WuTwenty historical case studies reveal how communication technology allows people to trust one another while mobilizing around a shared cause.Bloggers in India used social media and wikis to broadcast news and bring humanitarian aid to tsunami victims in South Asia. Terrorist groups like ISIS pour out messages and recruit new members on websites. The Internet is the new public square, bringing to politics a platform on which to create community at both the grassroots and bureaucratic level. Drawing on historical and contemporary case studies from more than ten countries, Irene S. Wu’s Forging Trust Communities argues that the Internet, and the technologies that predate it, catalyze political change by creating new opportunities for cooperation. The Internet does not simply enable faster and easier communication, but makes it possible for people around the world to interact closely, reciprocate favors, and build trust. The information and ideas exchanged by members of these cooperative communities become key sources of political power akin to military might and economic strength. Wu illustrates the rich world history of citizens and leaders exercising political power through communications technology. People in nineteenth-century China, for example, used the telegraph and newspapers to mobilize against the emperor. In 1970, Taiwanese cable television gave voice to a political opposition demanding democracy. Both Qatar (in the 1990s) and Great Britain (in the 1930s) relied on public broadcasters to enhance their influence abroad. Additional case studies from Brazil, Egypt, the United States, Russia, India, the Philippines, and Tunisia reveal how various technologies function to create new political energy, enabling activists to challenge institutions while allowing governments to increase their power at home and abroad. Forging Trust Communities demonstrates that the way people receive and share information through network communities reveals as much about their political identity as their socioeconomic class, ethnicity, or religion. Scholars and students in political science, public administration, international studies, sociology, and the history of science and technology will find this to be an insightful and indispensable work.

Forgotten Agricultural Heritage: Reconnecting food systems and sustainable development (Earthscan Food and Agriculture)
by Parviz Koohafkan Miguel A. AltieriContemporary agriculture is often criticized for its industrial scale, adverse effects on nutrition, rural employment and the environment, and its disconnectedness from nature and culture. Yet there are many examples of traditional smaller scale systems that have survived the test of time and provide more sustainable solutions while still maintaining food security in an era of climate change. This book provides a unique compilation of this forgotten agricultural heritage and is based on objective scientific evaluation and evidence of the value of these systems for present and future generations. The authors refer to many of these systems as Globally Important Agricultural Heritage Systems (GIAHS) and show how they are related to the concepts of heritage and the World Heritage Convention. They demonstrate how GIAHS based on family farms, traditional indigenous knowledge and agroecological principles can contribute to food and nutrition security and the maintenance of agro-biodiversity and environmental resilience, as well as sustain local cultures, economies and societies. Two substantial chapters are devoted to descriptions and assessments of some 50 examples of designated and potential GIAHS from around the world, including rice-fish culture in China, mountain terrace systems in Asia, coffee agroforestry in Latin America, irrigation systems and land and water management in Iran and India, pastoralism in East Africa, and the dehesa agrosilvopastoral system of Spain and Portugal. The book concludes by providing policy and technical solutions for sustainable agriculture and rural development through the enhancement of these systems.
Forgotten Fires of Chicago: The Lake Michigan Inferno and a Century of Flame (Disaster Ser.)
by John F. Hogan Alex A. BurkholderA historical journey through the city&’s catastrophic fires, and the stories of the heroes who fought them. Chicago&’s war against cinder, flame, and smoke did not end with the Great Fire of 1871. In 1909, fire ripped through the dynamite room of a staging facility a mile and half off the Lake Michigan shoreline, transforming the pipe-laying operation into a raging inferno. During the World&’s Columbian Exposition, thousands of fairgoers watched in horror as twelve firefighters were trapped in a blazing ice warehouse. An opera-goer left a smoking bomb under his seat at the Auditorium Theater in 1917. And the newly invented smoke ejector arrived too late to save firemen and laborers cut off in a sewer in 1931. Join John F. Hogan and Alex A. Burkholder for the history of these forgotten fires—and those who responded to them. &“A must-read not only for first responders but also all history buffs, especially those interested in Chicago history.&” —Robert Hoff, retired fire commissioner, Chicago Fire Department, from the foreword
The Forgotten Genius of Oliver Heaviside: A Maverick of Electrical Science
by Basil MahonOliver Heaviside (1850 -1925) may not be a household name but he was one of the great pioneers of electrical science: his work led to huge advances in communications and became the bedrock of the subject of electrical engineering as it is taught and practiced today. His ideas and original accomplishments are now so much a part of everyday electrical science that they are simply taken for granted; almost nobody wonders how they came about and Heaviside's name has been lost from view. This book tells the complete story of this extraordinary though often unappreciated scientist. The author interweaves details of Heaviside's life and personality with clear explanations of his many important contributions to the field of electrical engineering. He describes a man with an irreverent sense of fun who cared nothing for social or mathematical conventions and lived a fiercely independent life. His achievements include creating the mathematical tools that were to prove essential to the proper understanding and use of electricity, finding a way to rid telephone lines of the distortion that had stifled progress, and showing that electrical power doesn't flow in a wire but in the space alongside it. At first his ideas were thought to be weird, even outrageous, and he had to battle long and hard to get them accepted. Yet by the end of his life he was awarded the first Faraday Medal. This engrossing story will restore long-overdue recognition to a scientist whose achievements in many ways were as crucial to our modern age as those of Edison's and Tesla's.

Formal Analysis of Future Energy Systems Using Interactive Theorem Proving (SpringerBriefs in Applied Sciences and Technology)
by Asad Ahmed Osman Hasan Falah Awwad Nabil BastakiThis book describes an accurate analysis technique for energy systems based on formal methods—computer-based mathematical logic techniques for the specification, validation, and verification of the systems. Correctness and accuracy of the financial, operational, and implementation analysis are of the paramount importance for the materialization of the future energy systems, such as smart grids, to achieve the objectives of cost-effectiveness, efficiency, and quality-of-service. In this regard, the book develops formal theories of microeconomics, asymptotic, and stability to support the formal analysis of generation and distribution cost, smart operations, and processing of energy in a smart grid. These formal theories are also employed to formally verify the cost and utility modeling for: Energy generation and distribution;Asymptotic bounds for online scheduling algorithms for plug-in electric vehicles; andStability of the power converters for wind turbines. The proposed approach results in mechanized proofs for the specification, validation, and verification of corresponding smart grid problems. The formal mathematical theories developed can be applied to the formal analysis of several other hardware and software systems as well, making this book of interest to researchers and practicing engineers in a variety of power electronic fields.

Formal Development of a Network-Centric RTOS
by Eric Verhulst José Miguel Faria Raymond T. Boute Vitaliy Mezhuyev Bernhard H.C. SputhMany systems, devices and appliances used routinely in everyday life, ranging from cell phones to cars, contain significant amounts of software that is not directly visible to the user and is therefore called "embedded". For coordinating the various software components and allowing them to communicate with each other, support software is needed, called an operating system (OS). Because embedded software must function in real time (RT), a RTOS is needed. This book describes a formally developed, network-centric Real-Time Operating System, OpenComRTOS. One of the first in its kind, OpenComRTOS was originally developed to verify the usefulness of formal methods in the context of embedded software engineering. Using the formal methods described in this book produces results that are more reliable while delivering higher performance. The result is a unique real-time concurrent programming system that supports heterogeneous systems with just 5 Kbytes/node. It is compatible with safety related engineering standards, such as IEC61508.
Formal Languages, Automata and Numeration Systems, Volume 2
by Michel RigoThe interplay between words, computability, algebra and arithmetic has now proved its relevance and fruitfulness. Indeed, the cross-fertilization between formal logic and finite automata (such as that initiated by J.R. Büchi) or between combinatorics on words and number theory has paved the way to recent dramatic developments, for example, the transcendence results for the real numbers having a "simple" binary expansion, by B. Adamczewski and Y. Bugeaud. This book is at the heart of this interplay through a unified exposition. Objects are considered with a perspective that comes both from theoretical computer science and mathematics. Theoretical computer science offers here topics such as decision problems and recognizability issues, whereas mathematics offers concepts such as discrete dynamical systems.The main goal is to give a quick access, for students and researchers in mathematics or computer science, to actual research topics at the intersection between automata and formal language theory, number theory and combinatorics on words. The second of two volumes on this subject, this book covers regular languages, numeration systems, formal methods applied to decidability issues about infinite words and sets of numbers.
Formal Methods: Industrial Use from Model to the Code (Wiley-iste Ser. #692)
by Jean-Louis BoulangerAlthough formal analysis programming techniques may be quite old, the introduction of formal methods only dates from the 1980s. These techniques enable us to analyze the behavior of a software application, described in a programming language. It took until the end of the 1990s before formal methods or the B method could be implemented in industrial applications or be usable in an industrial setting. Current literature only gives students and researchers very general overviews of formal methods. The purpose of this book is to present feedback from experience on the use of “formal methods” (such as proof and model-checking) in industrial examples within the transportation domain. This book is based on the experience of people who are currently involved in the creation and evaluation of safety critical system software. The involvement of people from within the industry allows us to avoid the usual problems of confidentiality which could arise and thus enables us to supply new useful information (photos, architecture plans, real examples, etc.). Topics covered by the chapters of this book include SAET-METEOR, the B method and B tools, model-based design using Simulink, the Simulink design verifier proof tool, the implementation and applications of SCADE (Safety Critical Application Development Environment), GATeL: A V&V Platform for SCADE models and ControlBuild.

Formal Methods for Discrete-Time Dynamical Systems
by Calin Belta Boyan Yordanov Ebru Aydin GolThis book bridges fundamental gaps between control theory and formal methods. Although it focuses on discrete-time linear and piecewise affine systems, it also provides general frameworks for abstraction, analysis, and control of more general models. The book is self-contained, and while some mathematical knowledge is necessary, readers are not expected to have a background in formal methods or control theory. It rigorously defines concepts from formal methods, such as transition systems, temporal logics, model checking and synthesis. It then links these to the infinite state dynamical systems through abstractions that are intuitive and only require basic convex-analysis and control-theory terminology, which is provided in the appendix. Several examples and illustrations help readers understand and visualize the concepts introduced throughout the book.

Formal Verification of Floating-Point Hardware Design: A Mathematical Approach
by David M. RussinoffThis is the first book to focus on the problem of ensuring the correctness of floating-point hardware designs through mathematical methods. Formal Verification of Floating-Point Hardware Design, Second Edition advances a verification methodology based on a unified theory of register-transfer logic and floating-point arithmetic that has been developed and applied to the formal verification of commercial floating-point units over the course of more than two decades, during which the author was employed by several major microprocessor design companies. The theory is extended to the analysis of several algorithms and optimization techniques that are commonly used in commercial implementations of elementary arithmetic operations. As a basis for the formal verification of such implementations, high-level specifications of the basic arithmetic instructions of several major industry-standard floating-point architectures are presented, including all details pertaining to the handling of exceptional conditions. The methodology is illustrated in the comprehensive verification of a variety of state-of-the-art commercial floating-point designs developed by Arm Holdings. This revised edition reflects the evolving microarchitectures and increasing sophistication of Arm processors, and the variation in the design goals of execution speed, hardware area requirements, and power consumption. Many new results have been added to Parts I—III (Register-Transfer Logic, Floating-Point Arithmetic, and Implementation of Elementary Operations), extending the theory and describing new techniques. These were derived as required in the verification of the new RTL designs described in Part V.
Formal Verification of Floating-Point Hardware Design: A Mathematical Approach
by David M. Russinoff J Strother MooreThis is the first book to focus on the problem of ensuring the correctness of floating-point hardware designs through mathematical methods. Formal Verification of Floating-Point Hardware Design advances a verification methodology based on a unified theory of register-transfer logic and floating-point arithmetic that has been developed and applied to the formal verification of commercial floating-point units over the course of more than two decades, during which the author was employed by several major microprocessor design companies. The book consists of five parts, the first two of which present a rigorous exposition of the general theory based on the first principles of arithmetic. Part I covers bit vectors and the bit manipulation primitives, integer and fixed-point encodings, and bit-wise logical operations. Part II addresses the properties of floating-point numbers, the formats in which they are encoded as bit vectors, and the various modes of floating-point rounding. In Part III, the theory is extended to the analysis of several algorithms and optimization techniques that are commonly used in commercial implementations of elementary arithmetic operations. As a basis for the formal verification of such implementations, Part IV contains high-level specifications of correctness of the basic arithmetic instructions of several major industry-standard floating-point architectures, including all details pertaining to the handling of exceptional conditions. Part V illustrates the methodology, applying the preceding theory to the comprehensive verification of a state-of-the-art commercial floating-point unit. All of these results have been formalized in the logic of the ACL2 theorem prover and mechanically checked to ensure their correctness. They are presented here, however, in simple conventional mathematical notation. The book presupposes no familiarity with ACL2, logic design, or any mathematics beyond basic high school algebra. It will be of interest to verification engineers as well as arithmetic circuit designers who appreciate the value of a rigorous approach to their art, and is suitable as a graduate text in computer arithmetic.
