Computer Science and Statistics: Proceedings of the 13th Symposium on the Interface


Book Description

The 13th Symposium on the Interface continued this series after a one year pause. The objective of these symposia is to provide a forum for the interchange of ideas of common concern to computer scientists and statisticians. The sessions of the 13th Symposium were held in the Pittsburgh Hilton Hotel, Gateway Center, Pittsburgh. Following established custom the 13th Symposium had organized workshops on various topics of interest to participants. The workshop format allowed the invited speakers to present their material variously as formal talks, tutorial sessions and open discussion. The Symposium schedule was also the customary one. Registration opened in late afternoon of March 11, 1981 and continued during the opening mixer held that evening: The formal opening of the Symposium was on the morning of March 12. The opening remarks were followed by Bradley Efron's address "Statistical Theory and the Computer." The rest of the daily schedule was three concurrent workshops in the morning and three in the afternoon with contributed poster sessions during the noon break. Additionally there were several commercial displays and guided tours of Carnegie-Mellon University's Computer Center, Computer Science research facilities, and Robotics Institute.




Minuteman


Book Description

In Minuteman: A Technical History of the Missile That Defined American Nuclear Warfare, David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch—making it the ultimate ICBM. Minuteman offers a fascinating look at the technological breakthroughs necessary to field this weapon system that has served as a powerful component of the strategic nuclear triad for more than half a century. With exacting detail, Stumpf examines the construction of launch and launch control facilities; innovations in solid propellant, lightweight inertial guidance systems, and lightweight reentry vehicle development; and key flight tests and operational flight programs—all while situating the Minuteman program in the context of world events. In doing so, the author reveals how the historic missile has adapted to changing defense strategies—from counterforce to mutually assured destruction to sufficiency.







A Theory and Applications of Filamentary Structures


Book Description

A theory of filamentary structures consisting of monotropic membranes is presented. Applications to isotensoid pressure vessels with rotational symmetry demonstrate the use of the theory. Particular attention is given to applications of filamentary design of variable-geometry expandable structures. An extension of the theory to pressurized-filamentary structures subject to centrifugal loading and the special case of meridional winding patterns are presented in two Appendices. Physical interpretation of the resulting shapes and winding patterns leads to a discussion of the morphology of filament-wound pressure vessels. Experimental data, obtained from filament-wound toroidal pressure vessels, confirm the validity of the theory and demonstrate application of the analytical design technique for filamentary structures.

Seeing Trees


Book Description

"A deep . . . dive into urban society's need for--and relationship with--trees that sought to return the natural world to the concrete jungle."--Adrian Higgins, Washington Post Winner of the Foundation for Landscape Studies' 2019 John Brinckerhoff Jackson Prize Today, cities around the globe are planting street trees to mitigate the effects of climate change. However, as landscape historian Sonja Dümpelmann explains, the planting of street trees in cities to serve specific functions is not a new phenomenon. In her eye-opening work, Dümpelmann shows how New York City and Berlin began systematically planting trees to improve the urban climate during the nineteenth century, presenting the history of the practice within its larger social, cultural, and political contexts. A unique integration of empirical research and theory, Dümpelmann's richly illustrated work uncovers this important untold story. Street trees--variously regarded as sanitizers, nuisances, upholders of virtue, economic engines, and more--reflect the changing relationship between humans and nonhuman nature in urban environments. Offering valuable insights and frameworks, this authoritative volume will be an important resource for years to come.
