For a brief period during the latter part of World War II, Nevill F. Mott led a theoretical group at Fort Halstead in the United Kingdom that tackled scientific issues related to pressing war-time concerns. Among later awards and honors, Mott was knighted and a recipient of the Nobel Prize. While at Fort Halstead, he undertook an effort to theoretically describe the statistical fragmentation of munitions subjected to intense explosive loading. Mott`s original internal reports contain seminal theoretical concepts on the physics and statistics of dynamic fracture and fragmentation, which have provided the inspiration for numerous later modeling efforts and engineering formulae. Some of his most forward-looking thoughts on the micromechanical and molecular aspects of fracture are included in these publications. The present book surveys the theoretical analysis put forth by Mott with particular focus on his efforts to characterize the size and distribution of fragments resulting from a dynamic fragmentation event. Copies of the original internal reports of Mott and his co-workers are included. The book also pursues additional theoretical analysis with the intent of delving further into the physical ideas and unfinished analysis implicit in Mott`s original studies. This book will be of interest to all scientists and engineers concerned with the dynamic fracture and fragmentation of solid bodies subject to intense transient loads imparted by explosive detonation and high-velocity impact from both the historical and modern perspective.

"Fully updated and expanded, this new edition presents a cutting-edge summary of planetary rings and a wealth of exciting space mission results which have greatly increased our understanding of rings in recent years, including Cassini's initial Saturn System mission and its extended Equinox and Solstice missions, and the New Horizons flyby of Jupiter. Larry Esposito draws on his 40 years' research experience, including his position as a principal investigator within the Cassini mission team, to present all aspects of planetary rings, emphasizing ring history and evolution. The book introduces basic physical processes and simple mathematical approaches in a clear, accessible manner, including N-body and stochastic models of ring dynamics. Further revised chapters present highlighted topics including Saturn's F ring, Uranus' rings and moons, Neptune's partial rings, dusty rings, and Jupiter's ring-moon system including information from Galileo and New Horizons. Cassini results are fully integrated throughout, including new images in color, and a helpful new Afterword links each of the ring images in the Cassini 'Hall of Fame' gallery to the relevant explanation in the text. The book is also supported by an online cache of selected images and videos from the NASA collection, making it easy to locate the most relevant and beautiful illustrative materials available"--

This comprehensive handbook brings together experts who use optimization to solve problems that arise in telecommunications. It is the first book to cover in detail the field of optimization in telecommunications. Recent optimization developments that are frequently applied to telecommunications are covered. The spectrum of topics covered includes planning and design of telecommunication networks, routing, network protection, grooming, restoration, wireless communications, network location and assignment problems, Internet protocol, World Wide Web, and stochastic issues in telecommunications. The book’s objective is to provide a reference tool for the increasing number of scientists and engineers in telecommunications who depend upon optimization.
