Outrigger Design for High-Rise Buildings: An Output Of The Ctbuh Outrigger Working Group
by Hi Sun Choi Goman Ho Leonard Joseph Neville Mathias CtbuhOutrigger systems are rigid horizontal structures designed to improve a building’s stability and strength by connecting the building core or spine to distant columns, much in the way an outrigger can prevent a canoe from overturning. Outriggers have been used in tall, narrow buildings for nearly 500 years, but the basic design principle dates back centuries. In the 1980s, as buildings grew taller and more ambitious, outrigger systems eclipsed tubular frames as the most popular structural approach for supertall buildings. Designers embraced properly proportioned core-and-outrigger schemes as a method to offer far more perimeter flexibility and openness for tall buildings than the perimeter moment or braced frames and bundled tubes that preceded them. However, the outrigger system is not listed as a seismic lateral load-resisting system in any code, and design parameters are not available, despite the increasingly frequent use of the concept. The Council on Tall Buildings and Urban Habitat’s Outrigger Working Group has addressed the pressing need for design guidelines for outrigger systems with this guide, a comprehensive overview of the use of outriggers in skyscrapers. This guide offers detailed recommendations for analysis of outriggers within the lateral load-resisting systems of tall buildings, for recognizing and addressing effects on building behavior and for practical design solutions. It also highlights concerns specific to the outrigger structural system such as differential column shortening and construction sequence impacts. Several project examples are explored in depth, illustrating the role of outrigger systems in tall building designs and providing ideas for future projects. The guide details the impact of outrigger systems on tall building designs, and demonstrates ways in which the technology is continuously advancing to improve the efficiency and stability of tall buildings around the world.

Outsider Scientists: Routes to Innovation in Biology
by Oren Harman Michael R. DietrichOutsider Scientists describes the transformative role played by "outsiders" in the growth of the modern life sciences. Biology, which occupies a special place between the exact and human sciences, has historically attracted many thinkers whose primary training was in other fields: mathematics, physics, chemistry, linguistics, philosophy, history, anthropology, engineering, and even literature. These outsiders brought with them ideas and tools that were foreign to biology, but which, when applied to biological problems, helped to bring about dramatic, and often surprising, breakthroughs. This volume brings together eighteen thought-provoking biographical essays of some of the most remarkable outsiders of the modern era, each written by an authority in the respective field. From Noam Chomsky using linguistics to answer questions about brain architecture, to Erwin Schrödinger contemplating DNA as a physicist would, to Drew Endy tinkering with Biobricks to create new forms of synthetic life, the outsiders featured here make clear just how much there is to gain from disrespecting conventional boundaries. Innovation, it turns out, often relies on importing new ideas from other fields. Without its outsiders, modern biology would hardly be recognizable.
Outsmart Waste: The Modern Idea of Garbage and How to Think Our Way Out of It
by Tom SzakyGarbage has become a huge problem. Ever-expanding hazardous landfills, toxic waste dumps, ocean dead zones, endangered wildlife--it's an environmental nightmare. But garbage is a recent problem--for most of human history it was a minor annoyance--so we should be able to solve it. And garbage doesn't even exist in nature, where the output of one organism is the input of another. So why does garbage exist in human society? Why has it become a problem only in the last century? And most importantly, how can we eliminate it--outsmart the very idea of garbage? Eco-entrepreneur Tom Szaky says that to outsmart waste, first we have to understand it, then change how we create it, and finally rethink what we do with it. He traces the roots of our current garbage crisis to 20th-century social shifts and technological advances that resulted in historic changes in consuming habits--both the amount of garbage created and its longevity increased dramatically. We are now producing five billion tons of waste a year, and our only ways of dealing with it are crude and even dangerous: burying it or burning it. We can do better! Every time we make a purchase, we are essentially voting for the kind of world we want to live in. Szaky shows that by becoming acutely aware of the deeper implications of why we buy, what we buy, when we buy, and what we do with what we've bought, we can cast our vote for a waste-free world. And through innovative recycling and creative "upcycling" (creating new products from discarded objects), we can transform the waste we can't avoid creating from useless waste into a useful resource--as it is in nature. We do not have to turn the Earth into a cosmic trash can. We as individuals have the power to turn this situation around. And, as Szaky demonstrates, there is a use for every kind of garbage--cigarette butts, toothbrushes, pens, packaging, you name it. After reading this mind-expanding book, you will never think of garbage the same way again.
Outsourcing Energy Management: Saving Energy and Carbon through Partnering
by Steven FawkesThis book describes energy management outsourcing as a way of addressing the current energy challenges facing all organizations, namely high and volatile energy prices, the need to mitigate climate change and potential supply constraints as oil production peaks. These problems are likely to intensify in the coming years, yet most organizations have reduced in-house capability to address them, thus outsourcing is increasingly seen as an essential part of any strategy to reduce energy use and carbon emissions. The author describes the basic processes of energy management and how to outsource them in a strategic way to achieve maximum results. The process is based on a new model of energy management looking at total costs, which is presented in the book. The book offers a comprehensive guide to outsourcing energy management, discussing the risks and benefits and taking managers through the process of deciding whether to outsource or not, and finding and assessing an outsourcing partner. Managers looking to reduce energy consumption and carbon emissions through the use of external service providers will find Outsourcing Energy Management an ideal 'how to do it' guide.

Outsourcing the Global War on Terrorism
by George C. LovewineOutsourcing the Global War on Terrorism explores how the United States' war on terrorism, in both Iraq and Afghanistan, has required the US military to employ thousands of contracted civilians working for US and foreign Private Military and Private Security Companies (PMSCs). The actions and operations of unsupervised PMSCs has created an environment that had the potential to not only negatively influence tactical US objectives, but could also harm strategic local capacity-building initiatives. Given the military and political importance of US operations in Iraq and Afghanistan, George C. Lovewine provides a much-needed analysis of the interaction between commercial entities, military operations, and policy objectives. Lovewine's analyses identify the reactions and policy responses to these security issues faced by the United States military today.
Outsourcing War and Peace
by Laura A. DickinsonOver the past decade, states and international organizations have shifted a surprising range of foreign policy functions to private contractors. But who is accountable when the employees of foreign private firms do violence or create harm? This timely book describes the services that are now delivered by private contractors and the threat this trend poses to core public values of human rights, democratic accountability, and transparency. The author offers a series of concrete reforms that are necessary to expand traditional legal accountability, construct better mechanisms of public participation, and alter the organizational structure and institutional culture of contractor firms. The result is a pragmatic, nuanced, and comprehensive set of responses to the problem of foreign affairs privatization.
Oval: A Novel
by Elvia WilkBizarre weather. Unprecedented economic disparity. Artists employed by corporations. And the ultimate work of art: Oval, a pill that increases generosity. This unforgettable debut novel asks questions of empathy and power on every scale—from bodies to bureaucracies—to create an unsettling portrait of the future. In the near future, Berlin’s real estate is being flipped in the name of “sustainability,” only to make the city even more unaffordable; artists are employed by corporations as consultants, and the weather is acting strange. When Anja and Louis are offered a rent-free home on an artificial mountain—yet another eco-friendly initiative run by a corporation—they seize the opportunity, but it isn’t long before the experimental house begins malfunctioning.After Louis’s mother dies, Anja is convinced he has changed. At work, Louis has become obsessed with a secret project: a pill called Oval that temporarily rewires the user’s brain to be more generous. While Anja is horrified, Louis believes he has found the solution to Berlin’s income inequality. Oval is a fascinating portrait of the unbalanced relationships that shape our world, as well as a prescient warning of what the future may hold.”A fascinating near-future exploration of relationships, sustainability, and power.

Overcomplicated: Technology at the Limits of Comprehension
by Samuel ArbesmanWhy did the New York Stock Exchange suspend trading without warning on July 8, 2015? Why did certain Toyota vehicles accelerate uncontrollably against the will of their drivers? Why does the programming inside our airplanes occasionally surprise its creators? After a thorough analysis by the top experts, the answers still elude us. You don't understand the software running your car or your iPhone. But here's a secret: neither do the geniuses at Apple or the Ph.D.'s at Toyota--not perfectly, anyway. No one, not lawyers, doctors, accountants, or policy makers, fully grasps the rules governing your tax return, your retirement account, or your hospital's medical machinery. The same technological advances that have simplified our lives have made the systems governing our lives incomprehensible, unpredictable, and overcomplicated. In Overcomplicated, complexity scientist Samuel Arbesman offers a fresh, insightful field guide to living with complex technologies that defy human comprehension. As technology grows more complex, Arbesman argues, its behavior mimics the vagaries of the natural world more than it conforms to a mathematical model. If we are to survive and thrive in this new age, we must abandon our need for governing principles and rules and accept the chaos. By embracing and observing the freak accidents and flukes that disrupt our lives, we can gain valuable clues about how our algorithms really work. What's more, we will become better thinkers, scientists, and innovators as a result. Lucid and energizing, this book is a vital new analysis of the world heralded as "modern" for anyone who wants to live wisely.

Overconnected: The Promise and Threat of the Internet
by William H. Davidow&“Shows how the unanticipated effects of the Internet are distorting economics, politics, international relations, and individual lives&” (James Fallows). In Overconnected, Bill Davidow, a former Silicon Valley executive, explains how the almost miraculous success of the Internet has also created a unique set of hazards, in effect overconnecting us, with the direst of consequences for our political, economic, and day-to-day lives. The practical applications—not least among them the ability to borrow money, invest in the stock market, or buy a new home—have made a great impact in our daily lives. But the luxuries of the connected age have taken on a momentum all of their own, ultimately becoming the root cause of a financial meltdown from which much of the world is now still struggling to recover. By meticulously and counter-intuitively anatomizing how being overconnected tends to create systems of positive feedback that have largely negative consequences, Davidow explains everything from the subprime-mortgage crisis to the meltdown of Iceland, from the loss of people&’s privacy to the spectacular fall of the stock market that forced the Federal Government to rescue institutions supposedly &“too big to fail.&” All because we were so miraculously wired together! Explaining how such symptoms of Internet connection as unforeseeable accidents and thought contagions acted to accelerate the downfall and make us permanently vulnerable to catastrophe, Davidow places our recent experience in historical perspective and offers a set of practical steps to minimize similar disasters in the future. Original, commonsensical and historically informed, Overconnected indentifies problems we live with that are now so large, omnipresent and part of our daily lives that few people have even noticed them.
Overcurrent Protection NEC Article 240 and Beyond
by Gregory P. BieralsAn overcurrent is caused by a short-circuit, ground-fault, or an overload. A short-circuit may be hundreds or even thousands of times above the normal operating current. This type of fault may be an arcing fault between ungrounded conductors or between an ungrounded conductor and a grounded (usually, a neutral) conductor, a line-to-line arcing fault may produce a current of 74% of a 3-phase bolted fault. A line-to-neutral arcing fault will be somewhat less. A line-to-line bolted fault, the equivalent, of the conductors bolted together, may be up to 100% of the available short-circuit current. A line-to-neutral bolted fault may be in excess of 100% of the 3-phase bolted fault at the source, but considerably less downstream. A ground-fault, that is, the equivalent of a connection between an ungrounded conductor and the equipment grounding system, will produce a current that may be 38% or higher of the 3-phase bolted fault current. These types of faults are typically arcing faults which normally are intermittent in nature. That is, they strike and restrike over time and may produce a short-circuit fault due to insulation damage. Once again, a line-to-equipment ground fault near the source may produce a fault current of over 100% of the 3-phase bolted fault, but considerably less downstream. An overload typically ranges from one to six times the normal current, and are normally caused by motor starting currents or transformer magnetizing currents. These conditions are of such short duration that the circuit components are not damaged. This book has a detailed analysis of these types of faults, along with explanations and examples of the various types of overcurrent protective devices to assure proper protection. This volume has extensive information on the application of overcurrent protection for conductors and equipment. The reader will be able to calculate fault currents as well as establishing the short-circuit withstand rating of conductor insulation and to determine the appropriate type of overcurrent devices based on circuit conditions. In addition, determining ground-fault currents for the purpose of selecting the proper size of equipment grounding conductors to establish an effective ground-fault current path is discussed in detail. Readership - Anyone involved with the design of overcurrent protection for electrical distribution systems from the system source to the electrical utilization equipment. The emphasis is placed on the design of the overcurrent protection for specific installations to assure proper protection for the circuit components regardless of the type of fault encountered.
