Imagine a blackout lasting not days, but weeks or months. Tens of millions of people over several states are affected. For those without access to a generator, there is no running water, no sewage, no refrigeration or light. Food and medical supplies are dwindling. Devices we rely on have gone dark. Banks no longer function, looting is widespread, and law and order are being tested as never before.
It isn’t just a scenario. A well-designed attack on just one of the nation’s three electric power grids could cripple much of our infrastructure—and in the age of cyberwarfare, a laptop has become the only necessary weapon. Several nations hostile to the United States could launch such an assault at any time. In fact, as a former chief scientist of the NSA reveals, China and Russia have already penetrated the grid. And a cybersecurity advisor to President Obama believes that independent actors—from “hacktivists” to terrorists—have the capability as well. “It’s not a question of if,” says Centcom Commander General Lloyd Austin, “it’s a question of when.”
And yet, as Koppel makes clear, the federal government, while well prepared for natural disasters, has no plan for the aftermath of an attack on the power grid. The current Secretary of Homeland Security suggests keeping a battery-powered radio.
In the absence of a government plan, some individuals and communities have taken matters into their own hands. Among the nation’s estimated three million “preppers,” we meet one whose doomsday retreat includes a newly excavated three-acre lake, stocked with fish, and a Wyoming homesteader so self-sufficient that he crafted the thousands of adobe bricks in his house by hand. We also see the unrivaled disaster preparedness of the Mormon church, with its enormous storehouses, high-tech dairies, orchards, and proprietary trucking company – the fruits of a long tradition of anticipating the worst. But how, Koppel asks, will ordinary civilians survive?
With urgency and authority, one of our most renowned journalists examines a threat unique to our time and evaluates potential ways to prepare for a catastrophe that is all but inevitable.

We will soon be able to meet and exceed the basic needs of every man, woman and child on the planet. Abundance for all is within our grasp. This bold, contrarian view, backed up by exhaustive research, introduces our near-term future, where exponentially growing technologies and three other powerful forces are conspiring to better the lives of billions. An antidote to pessimism by tech entrepreneur turned philanthropist, Peter H. Diamandis and award-winning science writer Steven Kotler.
Since the dawn of humanity, a privileged few have lived in stark contrast to the hardscrabble majority. Conventional wisdom says this gap cannot be closed. But it is closing—fast. The authors document how four forces—exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion—are conspiring to solve our biggest problems. Abundance establishes hard targets for change and lays out a strategic roadmap for governments, industry and entrepreneurs, giving us plenty of reason for optimism.
Examining human need by category—water, food, energy, healthcare, education, freedom—Diamandis and Kotler introduce dozens of innovators making great strides in each area: Larry Page, Steven Hawking, Dean Kamen, Daniel Kahneman, Elon Musk, Bill Joy, Stewart Brand, Jeff Skoll, Ray Kurzweil, Ratan Tata, Craig Venter, among many, many others.
A radical, how-to guide for using exponential technologies, moonshot thinking, and crowd-powered tools, Bold unfolds in three parts. Part One focuses on the exponential technologies that are disrupting today’s Fortune 500 companies and enabling upstart entrepreneurs to go from “I’ve got an idea” to “I run a billion-dollar company” far faster than ever before. The authors provide exceptional insight into the power of 3D printing, artificial intelligence, robotics, networks and sensors, and synthetic biology. Part Two draws on insights from billionaires such as Larry Page, Elon Musk, Richard Branson, and Jeff Bezos and reveals their entrepreneurial secrets. Finally, Bold closes with a look at the best practices that allow anyone to leverage today’s hyper-connected crowd like never before. Here, the authors teach how to design and use incentive competitions, launch million-dollar crowdfunding campaigns to tap into tens of billions of dollars of capital, and finally how to build communities—armies of exponentially enabled individuals willing and able to help today’s entrepreneurs make their boldest dreams come true.

Drs. Forbes and Ahmed focus mainly on lean construction methodologies, such as The Last Planner(R) System, The Lean Project Delivery System (TM), and Integrated Project Delivery(TM). The tools and strategies offered draw on the success of the world-renowned Toyota Production System (TPS) adapted to the construction environment by construction professionals and researchers involved in developing and advocating lean construction methods. The book also discusses why true lean construction can best occur when all the construction stakeholders, owners, designers, constructors, and material suppliers are committed to the concept of optimizing the flow of activities holistically while de-emphasizing their self-interest.
The authors also reintroduce process improvement approaches such as TQM and Six Sigma as a foundation for the adoption of lean methodologies, and demonstrate how these methods can improve projects in a so-called traditional environment. The book integrates these methods with emerging interest in "green construction" and the use of information technology and Building Information Modeling (BIM), while recognizing the human element in relation to motivation, safety, and environmental stresses. Written specifically for professionals in an industry that desperately needs to play catch up, the book delineates cutting-edge approaches with the benefit of successful cases and explains how their deployment can improve construction performance and competitiveness.
For this second revised edition, Professor Dettman included a new section on generalized functions to help explain the use of the Dirac delta function in connection with Green's functions. In addition, a new approach to series solutions of ordinary differential equations has made the treatment independent of complex variable theory. This means that the first six chapters can be grasped without prior knowledge of complex variables. However, since Chapter 8 depends heavily on analytic functions of a complex variable, a new Chapter 7 on analytic function theory has been written.

Each of the eight projects featured in this masterful narrative was a milestone in its own right: the flood-control works of the lower Mississippi, Hoover Dam, Edison's lighting system, the spread of electricity across the nation, the great Croton Aqueduct, the bridges of New York City, Boston's revamped street system, known as the Big Dig, and the ever-evolving communica- tions network called the Internet. Each project arose from a heroic vision. Each encountered obstacles. Each reveals a tale of genius and perseverance.
James Tobin, winner of a National Book Critics Circle Award, explains the four essential tasks of the engineer: to protect people from the destructive force of water while harnessing it for the enormous good it can do; to provide people with electricity, the motive force of modern life; to make great cities habitable and vital; and to create the pathways that connect place to place and person to person. Tobin focuses on the indi- viduals behind our greatest structures of earth and concrete and steel: James Buchanan Eads, who walked on the floor of the Mississippi to learn the river's secrets; Arthur Powell Davis and Frank Crowe, who imagined a dam that could transform the West; Thomas Edison, who envisioned a new way to light the world; Samuel Insull, the organizational mastermind of the electrical revolution; the long-forgotten John Bloomfield Jervis, who assured New York's future with the gift of clean water; Othmar Ammann, the modest Swiss-American who fought his mentor to become the first engineer to bridge the lower Hudson River; Fred Salvucci, the antihighway rebel who transformed the face of Boston; and J.C.R. Licklider, the obscure scientist who first imagined the Internet. Here, too, are the workers who scorned hardship to turn the engineers' dreams into reality, deep underground and high in the sky, through cold and heat and danger. In Great Projects -- soon to be a major PBS television series by the Emmy Award-winning Great Projects Film Company -- we share their dreams and witness their struggles; we watch them create the modern world we walk through each day -- the "city upon a hill" that became our America.

Introduction to Finite Element Analysis Using MATLAB and Abaqus introduces and explains theory in each chapter, and provides corresponding examples. It offers introductory notes and provides matrix structural analysis for trusses, beams, and frames. The book examines the theories of stress and strain and the relationships between them. The author then covers weighted residual methods and finite element approximation and numerical integration. He presents the finite element formulation for plane stress/strain problems, introduces axisymmetric problems, and highlights the theory of plates. The text supplies step-by-step procedures for solving problems with Abaqus interactive and keyword editions. The described procedures are implemented as MATLAB codes and Abaqus files can be found on the CRC Press website.

With contributions from a distinguished group of international experts, the book explores ways of controlling air pollution and mitigating its adverse effects on human health and the environment. Often taking a regional and global perspective, it discusses the monitoring and source characterization of air pollution, the theory and application of air quality modeling, health effects and risk assessment, and the environmental impacts of air pollution. The book also addresses air quality management and relevant policy issues.
Along with providing an understanding of the scientific basis of air pollution, this volume helps readers better appreciate social and environmental determinants of public health and apply country-based research evidence to reduce health disparities and environmental inequalities. It also encourages future research and policy action on the health and environmental consequences of air pollution from the local to global level.
This volume summarizes and evaluates the literature in the area of metal effects on fertility and reproduction in humans, laboratory animals, and wildlife. International experts have contributed chapters that explore how the ovary, testes, uterine system, and neuroendocrine system, among others, respond to metal exposure. Reviewing both current knowledge and cutting edge data, the chapters focus on either a particular metal or a particular population.
A massive amount of data on this subject has been generated, summarized, and reviewed over the years. While there are many books available on metals toxicity and on reproductive toxicity, no current book explores both in the same volume. Culling information from throughout the literature, Metals, Fertility, and Reproductive Toxicity supplies an in-depth look at the role of metals in endocrine disruption and the spectrum of mechanisms involving metals that can influence reproduction.
Quality measurement is not prevalent in the concrete industry and quality investment is not seen as potentially generating a positive return. Improving Concrete Quality examines how and why concrete quality should be measured, and includes instruction on developing specifications with the aim of improving concrete quality.
Reduce Concrete Variability: Reduce Costs and Increase Volume
The first part of the book considers the tangible and intangible benefits of improved quality. The later chapters explore concrete strength variability in detail. It provides a greater grasp of the variation in concrete, as well as a deeper understanding of how material variability affects concrete performance. The author discusses the components of variability (material, manufacturing, testing) and provides steps to measuring and reducing variability to improve the quality of concrete. The text also contains a chapter on data analysis for quality monitoring and test results.
Come Away with Practices and Tools That Can Be Applied Immediately:Provides techniques and how specifications can improve concrete quality Offers a clear understanding of the link between the materials (cement, SCM, aggregate, water, air), manufacturing, testing variability, and concrete quality Includes information on analyzing test data to improve quality
Improving Concrete Quality quantifies the benefits of improved quality, and introduces novel ways of measuring concrete quality. This text is an ideal resource for quality personnel in the concrete industry. It also benefits architects, engineers, contractors, and researchers.
