Trapped


Book Description

The day the blizzard started, no one knew that it was going to keep snowing for a week. That for those in its path, it would become not just a matter of keeping warm, but of staying alive. . . .Scotty and his friends Pete and Jason are among the last seven kids at their high school waiting to get picked up that day, and they soon realize that no one is coming for them. Still, it doesn't seem so bad to spend the night at school, especially when distractingly hot Krista and Julie are sleeping just down the hall. But then the power goes out, then the heat. The pipes freeze, and the roof shudders. As the days add up, the snow piles higher, and the empty halls grow colder and darker, the mounting pressure forces a devastating decision. . . .Michael Northrop is the New York Times bestselling author of TombQuest, an epic book and game adventure series featuring the magic of ancient Egypt. He is also the author of Trapped, an Indie Next List Selection, and Plunked, a New York Public Library best book of the year and an NPR Backseat Book Club selection. An editor at Sports Illustrated Kids for many years, he now writes full-time from his home in New York City. Learn more at www.michaelnorthrop.net.













The Prop Building Guidebook


Book Description

Theatre and film frequently require replicas of three-dimensional objects built for actors to use. This book lays the groundwork for an artisan to determine what materials and techniques to use to build these props. Walking the reader through the various tools and techniques used in historical and contemporary prop-making, the author present a process for deciding the materials and methods to build any prop. With an explanation of how the craft and its products have developed over time, the budding artisan will understand not just how and when to use certain techniques or materials, but also why to use them and what advantages they give. It arms the prop maker with a structured procedure for approaching the construction of any prop. Illustrated with step-by-step examples of how to use each construction method, and explanations of different types of materials, this book gives the beginner prop artisan a strong foundation to approach the construction of props and answers the question, "How should I begin?" The author is hosting an online component to the book along with his successful blog. It will feature additional resources for the prop maker, including books, shops, contact information, and how-to videos.




Algorithms - ESA 2007


Book Description

This book constitutes the refereed proceedings of the 15th Annual European Symposium on Algorithms, ESA 2007, held in Eilat, Israel, in October 2007 in the context of the combined conference ALGO 2007. The 63 revised full papers presented together with abstracts of three invited lectures address all current subjects in algorithmics reaching from design and analysis issues of algorithms over to real-world applications and engineering of algorithms in various fields.




Preventive Biomechanics


Book Description

How can we optimize a bedridden patient’s mattress? How can we make a passenger seat on a long distance flight or ride more comfortable? What qualities should a runner’s shoes have? To objectively address such questions using engineering and scientific methods, adequate virtual human body models for use in computer simulation of loading scenarios are required. The authors have developed a novel method incorporating subject studies, magnetic resonance imaging, 3D-CAD-reconstruction, continuum mechanics, material theory and the finite element method. The focus is laid upon the mechanical in vivo-characterization of human soft tissue, which is indispensable for simulating its mechanical interaction with, for example, medical bedding or automotive and airplane seating systems. Using the examples of arbitrary body support systems, the presented approach provides visual insight into simulated internal mechanical body tissue stress and strain, with the goal of biomechanical optimization of body support systems. This book is intended for engineers, manufacturers and physicians and also provides students with guidance in solving problems related to support system optimization.
