The Gauntlet
by Megan ShepherdPerfect for fans of Scott Westerfeld and The Maze Runner, The Gauntlet is the gripping finale to the thrilling and addictive Cage series about teens abducted from Earth by an otherworldly race—from Megan Shepherd, the New York Times bestselling author of the Madman’s Daughter series. Cora and her friends have escaped the Kindred station and landed at Armstrong—a supposed safe haven on a small moon—where they plan to regroup and figure out how to win the Gauntlet, the challenging competition to prove humanity’s intelligence and set them free. But Armstrong is no paradise; ruled by a power-hungry sheriff, it’s a violent world where the teens are enslaved and put to work in mines. As Nok’s due date grows closer, and Mali and Leon journey across space to rescue Cassian, the former inhabitants of the cage are up against impossible odds.With the whole universe at stake, Cora will do whatever it takes, including pushing her body and mind to the breaking point, to escape Armstrong and run the Gauntlet. But it isn’t just a deranged sheriff she has to overcome: the other intelligent species—the Axion, Kindred, Gatherers, and Mosca—all have their own reasons to stop her. Not knowing who to trust, Cora must rely on her own instincts to win the competition, which could change the world—though it might destroy her in the process.

Gear Accuracy: A Treatise on Gear Noise Excitation, Vibration Generation, and Dynamics of Operation (Mechanical Engineering Series)
by Stephen P. RadzevichThis book provides a comprehensive profile the range of developments in gear science and gear engineering mainly those related to noise emission and vibration generation. The problem of noise emission and vibration generation is a challenging one. This scientific and engineering problem requires efforts of gear experts of different areas, and it got no satisfactory solution yet. Gear experts of different countries (USA, Israel, Poland, and Ukraine) have contributed to this volume. The latest accomplishments in scientific theory of gearing, gear design, production, inspection, and application are covered by this volume. The readers’ attention is focused mainly on the achievements in the field that lead to a significant reduction of gear noise excitation and vibration generation in gearing of all designs, namely, in parallel-axes gearing, in intersected-axes gearing, and in crossed-axes gearing. The concept of geometrically-accurate gearing (parallel-axes gearing, intersected-axes gearing, and crossed-axes gearing) is lays in the foundation of the undertaken research on gear noise emission and vibration generation. To the best possible extent, the kinematical and geometrical components of the problem under consideration are outlined at the beginning of this volume of the book when the accuracy of gears are discussed. The illustration of the various aspects of the problem is provided in the rest sections of the book volume. In particular, the readers’ attention is focused here also on the key problems, the poor knowledge of the scientific theory of gearing may lead to. This latter issue arouses even in leading gear manufacturing companies. The bottom line is as follows: In order to succeed in solving the noise excitation, and the vibration generation problem in gearing, high level of proficiency in the scientific theory of gearing is a must, as this theory provides the user with an in-depth understanding of meshing of the gear teeth, as well as with powerful tools to solve gear problems of this sort in cases when something goes wrong.

Gear Heads: The Turbulent Rise of Robotic Sports
by Brad StoneIn the early nineties, a visionary special-effects guru named Marc Thorpe conjured a field of dreams different from any the world had seen before: It would be framed by unbreakable plastic instead of cornstalks; populated not by ghostly ballplayers but by remote-controlled robots, armed to the steely teeth, fighting in a booby-trapped ring. If you built it, they'd come all right. In Gearheads, Newsweek technology correspondent Brad Stone examines the history of robotic sports, from their cultish early years at universities and sci-fi conventions to today's televised extravaganzas -- and the turmoil that threatened the whole enterprise almost from the beginning. By turns a lively historical narrative, a legal thriller, and an exploration of a cultural and technological phenomenon, Gearheads is a funny and fascinating look at the sport of the future today.

Gears: Volume 1: Geometric and Kinematic Design (Springer Series in Solid and Structural Mechanics #10)
by Vincenzo VulloThe book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

Gears: Volume 3: A Concise History (Springer Series in Solid and Structural Mechanics #12)
by Vincenzo VulloThis book provides a compact history of gears, by summarizing the main stages of their development and the corresponding gradual acquisition of engineering expertise, from the antiquity to the Renaissance and the twentieth century. This brief history makes no claim to be exhaustive, since the topic is so extensive, complex and fascinating that it deserves an entire encyclopedia. Despite its brevity, the book debunks a number of popular misconceptions, such as the belief that the first literary description of a gear was supplied by Aristotle. It disproves not only this myth, but also other peremptory statements and/or axiomatic assumptions that have no basis in written documents, archaeological findings or other factual evidence. The book is chiefly intended for students and lecturers, historians of science and scientists, and all those who want to learn about the genesis and evolution of this topic.

Geek Heresy: Rescuing Social Change from the Cult of Technology
by Kentaro ToyamaIn 2004, Kentaro Toyama, an award-winning computer scientist, moved to India to start a new research group for Microsoft. Its mission: to explore novel technological solutions to the world’s persistent social problems. Together with his team, he invented electronic devices for under-resourced urban schools and developed digital platforms for remote agrarian communities. But after a decade of designing technologies for humanitarian causes, Toyama concluded that no technology, however dazzling, could cause social change on its own. Technologists and policy-makers love to boast about modern innovation, and in their excitement, they exuberantly tout technology’s boon to society. But what have our gadgets actually accomplished? Over the last four decades, America saw an explosion of new technologies - from the Internet to the iPhone, from Google to Facebook - but in that same period, the rate of poverty stagnated at a stubborn 13%, only to rise in the recent recession. So, a golden age of innovation in the world’s most advanced country did nothing for our most prominent social ill. Toyama’s warning resounds: Don’t believe the hype! Technology is never the main driver of social progress. Geek Heresy inoculates us against the glib rhetoric of tech utopians by revealing that technology is only an amplifier of human conditions. By telling the moving stories of extraordinary people like Patrick Awuah, a Microsoft millionaire who left his lucrative engineering job to open Ghana’s first liberal arts university, and Tara Sreenivasa, a graduate of a remarkable South Indian school that takes children from dollar-a-day families into the high-tech offices of Goldman Sachs and Mercedes-Benz, Toyama shows that even in a world steeped in technology, social challenges are best met with deeply social solutions.
