Mechanics of Creep Brittle Materials-l was published in 1989 as the proceedings of a Colloquium held in Leicester in the summer of 1988. The Colloquium examined the creep response of a wide range of materials, including metals, engineering ceramics and ice, with the aim of determining similarities in the response of these materials and the way in which their behaviour is modelled. The proceedings were structured so as nature of the Colloquium,...

Since its origin in 1978, the International Conference on Boundary Element Methods has provided the recognized and established forum for innovations in boundary element research. Practically all new ideas on boundary ele­ ments have been presented at these conferences and the resulting papers can be found in the published books. The conference brings together the most renowned scientists and engineers working on boundary element research throu...

The rapid pace of current developments in the theoretical, analytical, numerical and experimental fields of dynamic failure of materials called for an international seminar of workshop style aimed at improving the finding and understanding of solutions to the basic physical processes involved in dynamic failure. The Vienna Seminar DFM-l was held at the Technical University Vienna in the historic administration building in the city center under...

This book comprises an edited version of the Proceedings of the 2nd Interna­ tional Conference on Applications of Supercomputers in Engineering which took place at the Massachusetts Institute of Technology, Cambridge, USA during August 1991. The Conference was organized by the Wessex Insti­ tute of Technology, Southampton, UK with the support of the International Society for Boundary Elements. The first International Conference on Ap­ plicatio...

Primarily concerned with how the US government can outwit its former allies in the rush to exploit their former common enemy. Considers the US sluggishness in technological innovation, flaws in education and labor management, the dangers of free trade, and resource depletion. Annotation copyright Bo

flour, potato starch, cracking catalyst, sand, and gravel, one will probably agree that the first four materials definitely are powders and the last one certainly is not. Whether one would call sand a powder probably depends on the partiele size and on personal Vlews. When the astronaut Neil Armstrong returned to the Earth from his trip on the surface of the Moon, he stated: 'The surface is fine and powdery. I can kick it up loosely with my to...

The knowledge on materials of the Earth's interior has largely increased during the last twenty years owing to the development of high-pressure and high­ temperature techniques for material syntheses. We have now reasonable ideas on the major constituents of down to the lower mantle the Earth's interior in connection to the velocities of seismic waves. However, the studies of the materials science on the Earth have practically confined within ...

Silicon carbides have major industrial uses as high temperature structural ceramic materials. These two volumes are translated from the Japanese and provide a comprehensive account of the seminal work going on in Japan.

Three events, which happened all within the same week some ten years ago, set me on the track which the book describes. The first was a reading of Emile Meyerson works in the course of a prolonged research on Einstein's relativity theory, which sent me back to Meyerson's Ident­ ity and Reality, where I read and reread the striking chapter on "Ir­ rationality". In my earlier researches into the origins of French Conven­ tionalism I came to know...

This twentienth volume of ABHB (Annual bibliography oj the history oj the printed book and libraries) contains 3899 records, selected from some 2000 periodicals, the list of which follows this introduction. They have been compiled by the National Committees of the following countries: Latin America Arab countries Luxembourg Australia The Netherlands Austria Norway Belgium Poland Bulgaria Portugal Canada Rumania Denmark South Africa Finland Spa...

Mixed valency is one of various names used to describe compounds which contain ions of the same element in two different formal states of oxidation. The existence of mixed valency systems goes far back into the geological evolutionary history of the earth and other planets, while a plethora of mixed valency minerals has attracted attention since antiquity. Indeed, control of the oxidation states of Fe in its oxides (FeO, Fe304' Fe203) was eleg...

Monte Carlo simulation is now a well established method for studying semiconductor devices and is particularly well suited to highlighting physical mechanisms and exploring material properties. Not surprisingly, the more completely the material properties are built into the simulation, up to and including the use of a full band structure, the more powerful is the method. Indeed, it is now becoming increasingly clear that phenomena such as reli...

Life has shaped the Earth, and the Earth has moulded the history of life. That history, the co-evolution of our ancestors and their horne, has much to teach us about our place on the planet today. We are part of the fabric of the biosphere. As we change that fabric we would be wise to understand how our horne was built. Our planet is neither a hotel nor a colony. It is not a place which life briefly inhabits during a transient occupation. Inst...

The Generalized LR parsing algorithm (some call it "Tomita's algorithm") was originally developed in 1985 as a part of my Ph.D thesis at Carnegie Mellon University. When I was a graduate student at CMU, I tried to build a couple of natural language systems based on existing parsing methods. Their parsing speed, however, always bothered me. I sometimes wondered whether it was ever possible to build a natural language parser that could parse rea...

Kinetic theory is the link between the non--equilibrium statistical mechanics of many particle systems and macroscopic or phenomenological physics. Therefore much attention is paid in this book both to the derivation of kinetic equations with their limitations and generalizations on the one hand, and to the use of kinetic theory for the description of physical phenomena and the calculation of transport coefficients on the other hand. The book ...

Most of the papers appearing in volume 87 numbers, 1-2 are based on papers presented at the Colloquium on the Philosophy of Ludwig Wittgenstein held at the Department of Philosophy at Florida State University on 7-8 April 1989. We owe warm thanks to Florida State University for generously supporting this colloquium. The English translation of the chapter entitled 'Philosophie', from Wittgenstein's typescript number 213 (von Wright), appears he...

1. 1 Preliminary Concepts A cam mechanism is a mechanical system consisting of three basic components: a driving element, called the cam, a driven element, termed the follower, and a fixed frame. Sometimes, an intermediate element is introduced between the cam and the follower with the purpose of improving the mechanism performance. This element is called the roller because function is to produce a pure-rolling relative motion be­ tween the ca...
