193 pp.; 23.5 x 21 cm.; glue bound; black-and-white & color; edition size unknown; unsigned and unnumbered; offset-printed Monograph on Trevor Paglen''''s ambitious project "The Last Pictures." Foreword by Anne Pasternak and Nato Thompson. Texts by Katie Detwiler, Joel Weisberg, Rafael Núñez, Brian L. Wardle, Karl Berggren, with a statement by EchoStar Corporation. "Since 1963, more than eight hundred spacecraft have been launched into geosynchronous orbit, forming a man-made ring of satellites around the Earth. These satellites are destined to become the longest-lasting artifacts of human civilization, quietly floating through space long after every trace of humanity has disappeared from the planet. Trevor Paglen''''s The Last Pictures is a project that marks one of these spacecraft with a visual record of our contemporary historical moment. Paglen spent five years interviewing scientists, artists, anthropologists, and philosophers to consider what such a cultural mark should be. Working with materials scientists at Massachusetts Institute of Technology, Paglen developed an artifact designed to last billions of years--an ultra-archival disc, micro-etched with one hundred photographs and encased in a gold-plated shell. In Fall 2012, the communications satellite EchoStar XVI will launch into geostationary orbit with the disc mounted to its anti-earth deck. While the satellite''''s broadcast images are as fleeting as the light-speed radio waves they travel on, The Last Pictures will remain in outer space slowly circling the Earth until the Earth itself is no more. The conversation surrounding the selected images is vast and requires extraordinary specificity. More than a catalogue, The Last Pictures published with University of California Press acts as a critical compendium in examining the decision and implications of these 100 photographs." -- publisher''''s statement.

Taschenbuch. Zustand: Neu. Neuware - Experimental and numerical work was conducted to better understand composite shell response to transverse loadings which simulate damage-causing impact events. The quasi-static, centered, transverse loading response of laminated graphite/epoxy shells in a []/-45(sub n)/O(sub n)](sub s) layup having geometric characteristics of a commercial fuselage are studied. The singly-curved composite shell structures are hinged along the straight circumferential edges and are either free or simply supported along the curved axial edges. Key components of the shell response are response instabilities due to limit-point and/or bifurcation buckling. Experimentally, deflection-controlled shell response is characterized via load-deflection data, deformation-shape evolutions, and the resulting damage state. Finite element models are used to study the kinematically nonlinear shell response, including bifurcation, limit-points, and postbuckling. A novel technique is developed for evaluating bifurcation from nonlinear prebuckling states utilizing asymmetric spatial discretization to introduce numerical perturbations. Advantages of the asymmetric meshing technique (AMT) over traditional techniques include efficiency, robustness, ease of application, and solution of the actual (not modified) problems. The AMT is validated by comparison to traditional numerical analysis of a benchmark problem and verified by comparison to experimental data. Applying the technique, bifurcation in a benchmark shell-buckling problem is correctly identified. Excellent agreement between the numerical and experimental results are obtained for a number of composite shells although predictive capability decreases for stiffer (thicker) specimens which is attributed to compliance of the test fixture. Restraining the axial edge (simple support) has the effect of creating a more complex response which involves unstable bifurcation, limit-point buckling, and dynamic collapse.
