Some probability problems are so difficult that they stump the smartest mathematicians. But even the hardest of these problems can often be solved with a computer and a Monte Carlo simulation, in which a random-number generator simulates a physical process, such as a million rolls of a pair of dice. This is what Digital Dice is all about: how to get numerical answers to difficult probability problems without having to solve complicated mathematical equations. Popular-math writer Paul Nahin challenges readers to solve twenty-one difficult but fun problems, from determining the odds of coin-flipping games to figuring out the behavior of elevators. Problems build from relatively easy (deciding whether a dishwasher who breaks most of the dishes at a restaurant during a given week is clumsy or just the victim of randomness) to the very difficult (tackling branching processes of the kind that had to be solved by Manhattan Project mathematician Stanislaw Ulam). In his characteristic style, Nahin brings the problems to life with interesting and odd historical anecdotes. Readers learn, for example, not just how to determine the optimal stopping point in any selection process but that astronomer Johannes Kepler selected his second wife by interviewing eleven women. The book shows readers how to write elementary computer codes using any common programming language, and provides solutions and line-by-line walk-throughs of a MATLAB code for each problem. Digital Dice will appeal to anyone who enjoys popular math or computer science. In a new preface, Nahin wittily addresses some of the responses he received to the first edition.

An exciting travel guide for Upstate New York road warriors, history lovers, and tourists. In Upstate Uncovered Chuck D’Imperio mines deep into his travel journal and shares an astonishing array of fun and amazing places in Upstate New York that the casual traveler might otherwise miss. As one of Upstate’s most ardent advocates, D’Imperio has traveled the backroads and byways of the region seeking out the stories, tales, and folklore writ upon the landscape. He takes readers to one hundred small towns and cities from the Hudson Valley to the High Peaks of the Adirondacks and out through the rolling hills of the Finger Lakes region. Not only a reflection of “the road less traveled,” Upstate Uncovered includes pertinent information such as websites, photographs, personal interviews, and explicit directions to each of the included entries. While flipping through the pages, readers will be amazed at what turns up around every backroads corner in the region. “This book is a delight. It’s raw meat for people (like me) who love to find and enjoy obscure historical treasures, but it is much more. Anyone who lives or travels in Upstate New York will be surprised and delighted at how much there is to discover and enjoy there. The nation’s smallest church? The grave of ‘The Moses of her people?’ New York’s biggest pair of pants? The town where ‘Oz’ began? A two-story outhouse? (You read it right.) The birthplace of The Twilight Zone? They’re all here, and more, in witty, warm, and lucid prose. Enjoy. You will.” — Mac Nelson, author of Twenty West: The Great Road Across America “Upstate New York—the area north of New York City—is full of interesting and historically significant places to visit, explore, and enjoy. Much of its history has been slighted or overlooked. Chuck D’Imperio seems to have visited just about every community in New York in the course of his research for Upstate Uncovered and previous excellent books on the region. D’Imperio has a flair for descriptive and evocative writing, bringing history to life through his on-site interviews and shrewd historical observations. This is exciting history, well told, and engaging. Even readers who know New York history will find lots of surprises and new insights. Upstate Uncovered conveys a deep sense of the variety, vitality, and drama of Upstate New York’s history.” — Bruce W. Dearstyne, author of The Spirit of New York: Defining Events in the Empire State’s History

The International Conference on Mechanical Design and Production has over the years established itself as an excellent forum for the exchange of ideas in these established fields. The first of these conferences was held in 1979. The seventh, and most recent, conference in the series was held in Cairo during February 15-17, 2000. International engineers and scientists gathered to exchange experiences and highlight the state-of-the-art research in the fields of mechanical design and production. In addition a heavy emphasis was placed on the issue of technology transfer. Over 100 papers were accepted for presentation at the conference. Current Advances in Mechanical Design & Production VII does not, however, attempt to publish the complete work presented but instead offers a sample that represents the quality and breadth of both the work and the conference. Ten invited papers and 54 ordinary papers have been selected for inclusion in these proceedings. They cover a range of basic and applied topics that can be classified into six main categories: System Dynamics, Solid Mechanics, Material Science, Manufacturing Processes, Design and Tribology, and Industrial Engineering and its Applications.

Hard Guidance on Preventing Disproportionate Collapse Disproportionate collapse is a pressing issue in current design practice. Numerous causes are possible – especially forms of extreme loading, such as blast, fire, earthquake, or vehicle collisions. But it is the mechanism and its prevention which are of especial interest and concern. After the World Trade Center collapse in 2001, interest was sparked, and it is now imperative for a design engineer to have sufficient knowledge on both the analysis and design against disproportionate collapse. Detailed structural design guidance for preventing this has been developed in Europe and the US – such as BS5950 in the UK, and guidance from the Department of Defense and the General Services Administration in the US. However, Structural Analysis and Design to Prevent Disproportionate Collapse is the first systematic text in the market to help design engineers or structural engineering students to properly understand this guidance. Covers the design and analysis of a structure to prevent disproportionate collapse Provides an understanding of disproportionate collapse problems for different structures under different loads Contains detailed knowledge on the design and progressive collapse analysis of complex structures Incorporates ABAQUS®, ETABS, SAP2000, and Highlights 3D Modeling Techniques As progressive collapse analysis is a distinctive and complicated procedure, it normally requires an ability to use a modern commercial finite element package, and Structural Analysis and Design to Prevent Disproportionate Collapse features a detailed introduction to the use of FE programs such as ABAQUS® in progressive collapse analysis. In addition, case studies are performed using 3D FE models based on various types of structures such as multi-storey buildings, long-span space structures, and bridges. These models replicate real collapse incidents and prestigious construction projects, such as progressive collapse analysis of the Twin Towers, structural fire analysis of World Trade Center 7, blast analysis of the Murrah Federal Building and progressive collapse analysis of the Millau Viaduct, which help designers to fully understand the failure mechanisms and effective mitigation methods in practice.
