Unified Theory of Concrete Structures develops an integrated theory that encompasses the various stress states experienced by both RC & PC structures under the various loading conditions of bending, axial load, shear and torsion. Upon synthesis, the new rational theories replace the many empirical formulas currently in use for shear, torsion and membrane stress. The unified theory is divided into six model components: a) the struts-and-ties model, b) the equilibrium (plasticity) truss model, c) the Bernoulli compatibility truss model, d) the Mohr compatibility truss model, e) the softened truss model, and f) the softened membrane model. Hsu presents the six models as rational tools for the solution of the four basic types of stress, focusing on the significance of their intrinsic consistencies and their inter-relationships. Because of its inherent rationality, this unified theory of reinforced concrete can serve as the basis for the formulation of a universal and international design code. Includes an appendix and accompanying website hosting the authors’ finite element program SCS along with instructions and examples Offers comprehensive coverage of content ranging from fundamentals of flexure, shear and torsion all the way to non-linear finite element analysis and design of wall-type structures under earthquake loading. Authored by world-leading experts on torsion and shear

Microelectronic packaging has been recognized as an important "enabler" for the solid state revolution in electronics which we have witnessed in the last third of the twentieth century. Packaging has provided the necessary external wiring and interconnection capability for transistors and integrated circuits while they have gone through their own spectacular revolution from discrete device to gigascale integration. At IBM we are proud to have created the initial, simple concept of flip chip with solder bump connections at a time when a better way was needed to boost the reliability and improve the manufacturability of semiconductors. The basic design which was chosen for SLT (Solid Logic Technology) in the 1960s was easily extended to integrated circuits in the '70s and VLSI in the '80s and '90s. Three I/O bumps have grown to 3000 with even more anticipated for the future. The package families have evolved from thick-film (SLT) to thin-film (metallized ceramic) to co-fired multi-layer ceramic. A later family or ceramics with matching expansivity to sili con and copper internal wiring was developed as a predecessor of the chip interconnection revolution in copper, multilevel, submicron wiring. Powerful server packages have been de veloped in which the combined chip and package copper wiring exceeds a kilometer. All of this was achieved with the constant objective of minimizing circuit delays through short, efficient interconnects.

As with the first edition, this textbook provides a clear introduction to the fundamental theory of structural analysis as applied to vehicular structures such as aircraft, spacecraft, automobiles and ships. The emphasis is on the application of fundamental concepts of structural analysis that are employed in everyday engineering practice. All approximations are accompanied by a full explanation of their validity. In this new edition, more topics, figures, examples and exercises have been added. There is also a greater emphasis on the finite element method of analysis. Clarity remains the hallmark of this text and it employs three strategies to achieve clarity of presentation: essential introductory topics are covered, all approximations are fully explained and many important concepts are repeated.

High-speed turnouts, a key technology for high-speed railways, have a great influence on the safe and stable running of high-speed trains. Design of High-Speed Railway Turnouts: Theory and Applications, comprehensively introduces the technical characteristics and requirements of high-speed turnouts, including design theories and methods of turnout layout geometry, wheel and rail relations, track stiffness, welded turnout, turnout conversion, turnout components, and manufacture and laying technologies of turnouts. Analyzing the operational problems of China’s high-speed turnout in particular, this book discusses the control of structure irregularity, state irregularity, geometrical irregularity and dynamic irregularity during the design, manufacture, laying, and maintenance of turnouts. At the end of this reference book, the author provides high-speed turnouts management methods, maintenance standards, testing and monitoring technology, and maintenance technology. Design of High-Speed Railway Turnouts: Theory and Applications will enable railway technicians all over the world to develop an in-depth knowledge of the design, manufacture, laying, and maintenance technology of high-speed turnouts. The first book in the world to focus explicitly on high-speed turnouts, including design, construction, maintenance and management of high speed turnouts Expounds the theory of vehicle-turnout system coupling dynamics in detail, aligning this with several examples of computation, and examines the results of dynamic experiments which validate the theory Written by Ping Wang, who is recognized as a leading researcher and main developer of high-speed turnouts in China

A New York Times Notable Book that “casts a searing eye on the labyrinth that is the American foster care system” (NPR’s On Point). Who are the children of foster care? What, as a country, do we owe them? Cris Beam, a foster mother herself, spent five years immersed in the world of foster care looking into these questions and tracing firsthand stories. The result is To the End of June, an unforgettable portrait that takes us deep inside the lives of foster children in their search for a stable, loving family. Beam shows us the intricacies of growing up in the system—the back-and-forth with agencies, the rootless shuffling between homes, the emotionally charged tug between foster and birth parents, the terrifying push out of foster care and into adulthood. Humanizing and challenging a broken system, To the End of June offers a tribute to resiliency and hope for real change. “A triumph of narrative reporting and storytelling.” —The New York Times “[A] powerful . . . and refreshing read.” —Chicago Tribune “A sharp critique of foster-care policies and a searching exploration of the meaning of family.” —Publishers Weekly (starred review) “Heart-rending and tentatively hopeful.” —Salon
