Trustworthy Execution on Mobile Devices
by Amit Vasudevan James Newsome Jonathan M. MccuneThis brief considers the various stakeholders in today's mobile device ecosystem, and analyzes why widely-deployed hardware security primitives on mobile device platforms are inaccessible to application developers and end-users. Existing proposals are also evaluated for leveraging such primitives, and proves that they can indeed strengthen the security properties available to applications and users, without reducing the properties currently enjoyed by OEMs and network carriers. Finally, this brief makes recommendations for future research that may yield practical and deployable results.
Trustworthy Hardware Design: Combinational Logic Locking Techniques (Analog Circuits and Signal Processing)
by Muhammad Yasin Jeyavijayan (JV) Rajendran Ozgur SinanogluWith the popularity of hardware security research, several edited monograms have been published, which aim at summarizing the research in a particular field. Typically, each book chapter is a recompilation of one or more research papers, and the focus is on summarizing the state-of-the-art research. Different from the edited monograms, the chapters in this book are not re-compilations of research papers. The book follows a pedagogical approach. Each chapter has been planned to emphasize the fundamental principles behind the logic locking algorithms and relate concepts to each other using a systematization of knowledge approach. Furthermore, the authors of this book are in a good position to be able to deliver such a book, as they contributed to this field significantly through numerous fundamental papers.

The Truth About Tesla: The Myth of the Lone Genius in the History of Innovation
by Christopher CooperA myth-busting biography of Nikola Tesla, the “enigmatic figure whose life and achievements appeal to historians, engineers, scientists, and many others” (Library Journal).Nikola Tesla, one of the greatest electrical inventors who ever lived, was rescued from obscurity in recent years, restored to his rightful place among historical luminaries. We’ve been told that his contributions to humanity were obscured by a number of nineteenth-century inventors and industrialists who took credit for his work or stole his patents outright. Most biographies repeat this familiar account of Tesla’s life, including his invention of alternating current, his falling out with Thomas Edison, how he lost billions in patent royalties to George Westinghouse, and his fight to prove that Guglielmo Marconi stole thirteen of his patents to “invent” radio. But what really happened?Newly uncovered information, however, proves that the popular account of Tesla’s life is itself very flawed. In The Truth About Tesla, Christopher Cooper sets out to prove that the conventional story not only oversimplifies history, it denies credit to some of the true inventors behind many of the groundbreaking technologies now attributed to Tesla, and perpetuates a misunderstanding about the process of innovation itself.Are you positive that Alexander Graham Bell invented the telephone? Are you sure the Wright Brothers were the first in flight? Think again! With a provocative foreword by Tesla biographer Marc J. Seifer, The Truth About Tesla is one of the first books to set the record straight, tracing the origin of some of the greatest electrical inventions to a coterie of colorful characters that conventional history has all but forgotten.Includes photographs
The Truth about Wuhan: How I Uncovered the Biggest Lie in History
by Dr. Andrew G. HuffShocking new insider information that shows what really happened in Wuhan, China, at the start of the COVID-19 outbreak and in the ensuing cover-up. The day that Dr. Andrew G. Huff left his senior scientist and vice president role at EcoHealth Alliance was one of the happiest days of his life due to the corruption he had witnessed at the organization. However, he never thought working there would be of any great consequence to the future. He was wrong. Because, as an EcoHealth Alliance insider, Dr. Huff had had a ringside seat to one of the biggest cover-ups in history. The Truth about Wuhan contains new research and a breakdown of how and why the development of COVID-19 in the United States and China was supported by the US government to collect intelligence on laboratories in China. Dr. Huff, an expert in the fields of bioterrorism and bio warfare, is a whistleblower who will show why the reasons the lab leak was covered up are incorrect. He worked on the classified research side of the program as a US government scientist. He knows the real how and why COVID-19 emerged. Besides exposing the conspiracy and cover-up, Dr. Huff also puts forth policy solutions and recommendations to prevent a lab leak virus from plaguing the world again. The Truth about Wuhan simply explains the complexity of the system that led to COVID-19&’s emergence; how the medical industrial complex grew and became entrenched in gain of function work after 9/11; why EcoHealth Alliance was the (almost) perfect intelligence collection cover; the policy actions and decision-making process as to why the United States government engaged in the COVID cover-up; how and why the United States swapped biotechnology with China and biomedical corporations; and the incentives for each of the actors or governments to engage and coordinate a global cover-up of COVID-19 origins. The Truth about Wuhan also shows how and why Dr. Anthony Fauci is intricately involved in the COVID cover-up; how scientists like EcoHealth Alliance president and CEO Dr. Peter Daszak rose to power and used their influence to corrupt science and the COVID origin investigation; and how the intelligence community likely orchestrated the cover-up with Dr. Anthony Fauci. Dr. Huff also provides personal harrowing accounts of how the US government waged a psychological operation against him to prevent him from speaking out. COVID-19 is the biggest lie, scandal, and intelligence failure in US history, and Dr. Andrew G. Huff is stepping out of the shadows to share his insider story about this failure that led to millions of deaths around the world.

The Truth Machine: A Social History of the Lie Detector (Johns Hopkins Studies in the History of Technology)
by Geoffrey C. BunnHow do you trap someone in a lie? For centuries, all manner of truth-seekers have used the lie detector. In this eye-opening book, Geoffrey C. Bunn unpacks the history of this device and explores the interesting and often surprising connection between technology and popular culture.Lie detectors and other truth-telling machines are deeply embedded in everyday American life. Well-known brands such as Isuzu, Pepsi Cola, and Snapple have advertised their products with the help of the "truth machine," and the device has also appeared in countless movies and television shows. The Charles Lindbergh "crime of the century" in 1935 first brought lie detectors to the public’s attention. Since then, they have factored into the Anita Hill–Clarence Thomas sexual harassment controversy, the Oklahoma City and Atlanta Olympics bombings, and one of the most infamous criminal cases in modern memory: the O. J. Simpson murder trial. The use of the lie detector in these instances brings up many intriguing questions that Bunn addresses: How did the lie detector become so important? Who uses it? How reliable are its results? Bunn reveals just how difficult it is to answer this last question. A lie detector expert concluded that O. J. Simpson was "one hundred percent lying" in a video recording in which he proclaimed his innocence; a tabloid newspaper subjected the same recording to a second round of evaluation, which determined Simpson to be "absolutely truthful."Bunn finds fascinating the lie detector’s ability to straddle the realms of serious science and sheer fantasy. He examines how the machine emerged as a technology of truth, transporting readers back to the obscure origins of criminology itself, ultimately concluding that the lie detector owes as much to popular culture as it does to factual science.
The Truth Machine: The Blockchain and the Future of Everything
by Paul Vigna Michael J. Casey<p>Big banks have grown bigger and more entrenched. Privacy exists only until the next hack. Credit card fraud is a fact of life. Many of the “legacy systems” once designed to make our lives easier and our economy more efficient are no longer up to the task. Yet there is a way past all this—a new kind of operating system with the potential to revolutionize vast swaths of our economy: the blockchain. <p>In <i>The Truth Machine</i>, Michael J. Casey and Paul Vigna demystify the blockchain and explain why it can restore personal control over our data, assets, and identities; grant billions of excluded people access to the global economy; and shift the balance of power to revive society’s faith in itself. They reveal the disruption it promises for industries including finance, tech, legal, and shipping. <p>Casey and Vigna expose the challenge of replacing trusted (and not-so-trusted) institutions on which we’ve relied for centuries with a radical model that bypasses them. <i>The Truth Machine</i> reveals the empowerment possible when self-interested middlemen give way to the transparency of the blockchain, while highlighting the job losses, assertion of special interests, and threat to social cohesion that will accompany this shift. With the same balanced perspective they brought to <i>The Age of Cryptocurrency</i>, Casey and Vigna show why we all must care about the path that blockchain technology takes—moving humanity forward, not backward.
The Truth of the Technological World: Essays on the Genealogy of Presence
by translated by Erik Butler Friedrich A. KittlerFriedrich Kittler (1943-2011) combined the study of literature, cinema, technology, and philosophy in a manner sufficiently novel to be recognized as a new field of academic endeavor in his native Germany. "Media studies," as Kittler conceived it, meant reflecting on how books operate as films, poetry as computer science, and music as military equipment. This volume collects writings from all stages of the author's prolific career. Exemplary essays illustrate how matters of form and inscription make heterogeneous source material (e. g. , literary classics and computer design) interchangeable on the level of function--with far-reaching consequences for our understanding of the humanities and the "hard sciences. " Rich in counterintuitive propositions, sly humor, and vast erudition, Kittler's work both challenges the assumptions of positivistic cultural history and exposes the over-abstraction and language games of philosophers such as Heidegger and Derrida. The twenty-three pieces gathered here document the intellectual itinerary of one of the most original thinkers in recent times--sometimes baffling, often controversial, and always stimulating.

The Truth Society: Science, Disinformation, and Politics in Berlusconi's Italy (Expertise: Cultures and Technologies of Knowledge)
by Noelle Molé ListonNoelle Molé Liston's The Truth Society seeks to understand how a period of Italian political spectacle, which regularly blurred fact and fiction, has shaped how people understand truth, mass-mediated information, scientific knowledge, and forms of governance. Liston scrutinizes Italy's late twentieth-century political culture, particularly the impact of the former prime minister and media mogul Silvio Berlusconi. By doing so, she examines how this truth-bending political era made science, logic, and rationality into ideas that needed saving.With the prevalence of fake news and our seeming lack of shared reality in the "post-truth" world, many people struggle to figure out where this new normal came from. Liston argues that seemingly disparate events and practices that have unfolded in Italy are historical reactions to mediatized political forms and particular, cultivated ways of knowing. Politics, then, is always sutured to how knowledge is structured, circulated, and processed. The Truth Society offers Italy as a case study for understanding the remaking of politics in an era of disinformation.

Tsukemono: Decoding the Art and Science of Japanese Pickling
by Ole G. Mouritsen Klavs StyrbækOne of the best-kept secrets of Japanese cuisine is a range of side dishes known as tsukemono (つけもの, 漬物). The word, pronounced ‘tskay-moh-noh,’ means ‘something that has been steeped or marinated’ (tsuke—steeped; mono—things). Although tsukemono are usually made from vegetables, some fruits, flowers, and a few rhizomes are also preserved this way; it is, therefore, more accurate to characterize them as ‘pickled foods.’ Their preparation makes use of one or more conservation techniques, involving ingredients such as salt, sugar, vinegar, alcohol, and herbs, in combination with methods including dehydration, marinating in salt and acidic liquids, fermentation, and curing. The process of making tsukemono amounts to more than just a simple way of preserving otherwise perishable fresh produce. Apart from its nutritional value, the dish stimulates the appetite, provides delicious taste sensations, and improves digestion, all while remaining an elegant study in simplicity and esthetic presentation. This book goes well beyond explaining the secrets of making crisp tsukemono. The authors discuss the cultural history and traditions associated with these pickled foods; provide recipes and outline techniques for preparing them at home with local ingredients; describe the healthful benefits and basic nutritional value to be found in the various types of pickles; and show how easy it is to serve them on a daily basis to stimulate the appetite or as condiments to accompany vegetable, fish, and meat dishes. The goal is to encourage the readers of this book to join us in a small culinary adventure that will allow us to expand and diversify our consumption of plant-based foods, which are so vital to our overall well-being. And along the way, there may be a few surprises.

Tubes: A Journey to the Center of the Internet
by Andrew Blum“Andrew Blum plunges into the unseen but real ether of the Internet in a journey both compelling and profound….You will never open an email in quite the same way again.”—Tom Vanderbilt, New York Times bestselling author of TrafficWhen your Internet cable leaves your living room, where does it go? Almost everything about our day-to-day lives—and the broader scheme of human culture—can be found on the Internet. But what is it physically? And where is it really? Our mental map of the network is as blank as the map of the ocean that Columbus carried on his first Atlantic voyage. The Internet, its material nuts and bolts, is an unexplored territory. Until now.In Tubes, journalist Andrew Blum goes inside the Internet's physical infrastructure and flips on the lights, revealing an utterly fresh look at the online world we think we know. It is a shockingly tactile realm of unmarked compounds, populated by a special caste of engineer who pieces together our networks by hand; where glass fibers pulse with light and creaky telegraph buildings, tortuously rewired, become communication hubs once again. From the room in Los Angeles where the Internet first flickered to life to the caverns beneath Manhattan where new fiber-optic cable is buried; from the coast of Portugal, where a ten-thousand-mile undersea cable just two thumbs wide connects Europe and Africa, to the wilds of the Pacific Northwest, where Google, Microsoft, and Facebook have built monumental data centers—Blum chronicles the dramatic story of the Internet's development, explains how it all works, and takes the first-ever in-depth look inside its hidden monuments.This is a book about real places on the map: their sounds and smells, their storied pasts, their physical details, and the people who live there. For all the talk of the "placelessness" of our digital age, the Internet is as fixed in real, physical spaces as the railroad or telephone. You can map it and touch it, and you can visit it. Is the Internet in fact "a series of tubes" as Ted Stevens, the late senator from Alaska, once famously described it? How can we know the Internet's possibilities if we don't know its parts?Like Tracy Kidder's classic The Soul of a New Machine or Tom Vanderbilt's recent bestseller Traffic, Tubes combines on-the-ground reporting and lucid explanation into an engaging, mind-bending narrative to help us understand the physical world that underlies our digital lives.
Tubes: A Journey to the Center of the Internet
by Andrew BlumAn engaging, narrative tour behind the scenes of our everyday lives to see the dark beating heart of the Internet itself.We are all connected now. But connected to what, exactly? In Tubes, journalist Andrew Blum takes readers on a fascinating journey to find out.When former Senator Ted Stevens of Alaska famously described the Internet as “a series of tubes,” he seemed hopelessly, foolishly trapped in an old way of knowing the world. But he wasn’t wrong. After all, as Blum writes, the Internet exists: for all the talk of the “placelessness” of our digital age, the Internet is as fixed in real, physical places as any railroad or telephone ever was. It fills enormous buildings, converges in some places and avoids others, and it flows through tubes under ground, up in the air, and under the oceans all over the world. You can map it, you can smell it, and you can even visit it—and that’s just what Blum does in Tubes.From the room in Berkeley where the Internet flickered to life to the busiest streets in Manhattan as new fiber optic cable is laid down; from the coast of Portugal as a 10,000-mile undersea cable just two thumbs’ wide is laid down to connect Europe and West Africa to the wilds of the Pacific Northwest, where Google, Microsoft and Facebook have built monumental data centers—Blum visits them all to chronicle the dramatic story of the Internet’s development, explain how it all works, and capture the spirit of the place/Like Tracy Kidder’s classic The Soul of a New Machine or Tom Vanderbilt’s recent bestseller Traffic, Tubes combines deep reporting and lucid explanation into an engaging quest to understand the everyday world we live in.
Tubular String Characterization in High Temperature High Pressure Oil and Gas Wells (Multiphysics Modeling)
by Jiuping Xu Zezhong WuHigh temperature, high oil pressure, oil and gas well completion testing have always been a technical challenge and basic theoretical research is one of the key factors needed to ensure a successful completion test. The completion test basic theory includes: a stress analysis of the completion string, completion string buckling behavior, and temperature and pressure distribution prediction. The completion string is the main bearing and power transmission component for oil and gas well operations and production, and it is required to take on a combination of loads, which result in completion string deformation. Because of these complex relationships, completion string stress analysis has become increasingly more complicated.This book discusses the characters of tubular strings in HTHP (High Temperature - High Pressure) oil and gas wells. These characters include the mechanical behavior of tubular strings and the temperature and pressure variation of tubular strings in different conditions. Mathematical models are established for different conditions and solution existence and uniqueness of some models is discussed, providing algorithms corresponding to the different models. Numerical experiments are presented to verify the validity of models and the feasibility of algorithms, and the impact of the parameters of models for oil and gas wells is also discussed.This book is written for production and testing engineers to provide them with the tools to deal more effectively with the numerical decisions they have to take and for researchers and technicians in petroleum and gas testing and production engineering. Finally, it is also intended to serve as a reference book for mathematicians, college teachers and students.
