Computers are the foundation of the information age, but communication technology is the foundation of the foundation. Without the theories and practical applications of theory brought to us by the pioneers of communication, the computer age would perhaps have remained in the back office, hidden away as infrastructure like electricity or running water – critical to modern life, but not as transforming as the combination of communications and computing. The information age exploded once machines were endowed with the ability to talk among themselves. The Signal connects everything to everything else, in both communication, and in the metaphorical sense as the link between and among people.Features Identifies the key ideas underlying modern communications technology, and documents the contributions of its inventors Explores the signal in communication, and also in the metaphorical sense as the link between and among people Leads the reader through a journey from ancient number systems to Voyager II to radio and MP3s to quantum cryptography Includes coverage of "Signals from Hell," including memes and "fake news" on the Internet Looks to the future of communication, with emergent 5G

A comprehensive look at the emerging science of networksNetwork science helps you design faster, more resilient communication networks; revise infrastructure systems such as electrical power grids, telecommunications networks, and airline routes; model market dynamics; understand synchronization in biological systems; and analyze social interactions among people.This is the first book to take a comprehensive look at this emerging science. It examines the various kinds of networks (regular, random, small-world, influence, scale-free, and social) and applies network processes and behaviors to emergence, epidemics, synchrony, and risk. The book's uniqueness lies in its integration of concepts across computer science, biology, physics, social network analysis, economics, and marketing.The book is divided into easy-to-understand topical chapters and the presentation is augmented with clear illustrations, problems and answers, examples, applications, tutorials, and a discussion of related Java software. Chapters cover: OriginsGraphsRegular NetworksRandom NetworksSmall-World NetworksScale-Free NetworksEmergenceEpidemicsSynchronyInfluence NetworksVulnerabilityNet GainBiologyThis book offers a new understanding and interpretation of the field of network science. It is an indispensable resource for researchers, professionals, and technicians in engineering, computing, and biology. It also serves as a valuable textbook for advanced undergraduate and graduate courses in related fields of study.

Covers critical infrastructure protection, providing a rigorous treatment of risk, resilience, complex adaptive systems, and sector dependenceWide in scope, this classroom-tested book is the only one to emphasize a scientific approach to protecting the key infrastructures components of a nation. It analyzes the complex network of entities that make up a nation's infrastructure, and identifies vulnerabilities and risks in various sectors by combining network science, complexity theory, risk analysis, and modeling and simulation. This approach reduces the complex problem of protecting water supplies, energy pipelines, telecommunication stations, power grid, and Internet and Web networks to a much simpler problem of protecting a few critical nodes.The new third edition of Critical Infrastructure Protection in Homeland Security: Defending a Networked Nation incorporates a broader selection of ideas and sectors than the previous book. Divided into three sections, the first part looks at the historical origins of homeland security and critical infrastructure, and emphasizes current policy. The second examines theory and foundations, highlighting risk and resilience in the context of complexity theory, network science, and the prevailing theories of catastrophe. The last part covers the individual sectors, including communications, internet, cyber threats, information technology, social networks, SCADA, water and water treatment, energy, and more. Covers theories of catastrophes, details of how sectors work, and how to deal with the problem of critical infrastructure protection’s enormity and complexityPlaces great emphasis on computer security and whole-community responseIncludes PowerPoint slides for use by lecturers, as well as an instructor's guide with answers to exercisesOffers five robust appendices that augment the non-mathematical chapters with more rigorous explanations and mathematicsCritical Infrastructure Protection in Homeland Security, Third Edition is an important book for upper-division undergraduates and first-year graduate students in political science, history, public administration, and computer technology. It will also be of great interest to professional security experts and policymakers.

Critical Infrastructure Resilience and Sustainability Reader Identify and protect critical infrastructure from a wide variety of threats In Critical Infrastructure Resilience and Sustainability Reader, Ted G. Lewis delivers a clear and compelling discussion of what infrastructure requires protection, how to protect it, and the consequences of failure. Through the book, you’ll examine the intersection of cybersecurity, climate change, and sustainability as you reconsider and reexamine the resilience of your infrastructure systems. The author walks you through how to conduct accurate risk assessments, make sound investment decisions, and justify your actions to senior executives. You’ll learn how to protect water supplies, energy pipelines, telecommunication stations, power grids, and a wide variety of computer networks, without getting into the weeds of highly technical mathematical models. Critical Infrastructure Resilience and Sustainability Reader also includes: A thorough introduction to the daunting challenges facing infrastructure and the professionals tasked with protecting itComprehensive explorations of the proliferation of cyber threats, terrorism in the global West, climate change, and financial market volatilityPractical discussions of a variety of infrastructure sectors, including how they work, how they’re regulated, and the threats they faceClear graphics, narrative guides, and a conversational style that makes the material easily accessible to non-technical readersPerfect for infrastructure security professionals and security engineering firms, Critical Infrastructure Resilience and Sustainability Reader will also benefit corporate security managers and directors, government actors and regulators, and policing agencies, emergency services, and first responders.

"This is a book that approaches resilience as a systems problem, examined through models, analogies and worked examples drawn from physics, ecology, engineering, finance and cyber security…  By using mathematical models and real-world examples, the book provides practical tools and strategies for designing resilient systems that can adapt and thrive in the face of uncertainty."- "Inspiration for Resilience Professionals." CIR Magazine, Q1 2026. https://www.cirmagazine.comStrategies for improving resilience, incorporating complexity theory, risk analysis, and systems thinking with a rigorous mathematical treatmentThe Science of Resilience delves into the fascinating field of resilience science, exploring how various systems, ranging from physical infrastructure to social networks, can withstand and recover from disruptions. This interdisciplinary subject combines principles from complexity theory, risk analysis, and systems thinking to understand and mitigate the impacts of events like natural disasters, cyber-attacks, and economic crises. By using mathematical models and real-world examples, the book provides practical tools and strategies for designing resilient systems that can adapt and thrive in the face of uncertainty.Written by a highly qualified author with significant experience in the field, this book: Covers synchronization, bottleneck analysis, epidemic modeling, social network disinformation and how to counter it, and restructuring a system to increase resilienceExplains phase change and shows how to apply it to general complex systemsIntegrates rigorous mathematical models with real-world applications through mini case studies and hypothetical examples covering physical, economic, and social systemsProvides tools and strategies to design resilient systems, analyze potential risks, and plain for resilienceAddressing an important gap in risk and resilience literature, this book offers valuable insights for engineering and systems design professionals, complexity science and risk analysis researchers, and graduate students in related fields, as well as anyone interested in the science of resilience.
