Unique in its breadth and detail, this encyclopedia offers a comprehensive and highly readable guide to a complex and fast-expanding field.

This book highlights many fundamental aspects of optical fiber transmission engineering while also focusing on current state of the art applications and working examples of digital coherent optical communications. Major engineering themes are reviewed and analyzed in this book, including spectral and time-domain characteristics of multi-level pseudo-random PAM signals, optical QAM and SSB complex modulations and impulse response engineering of linear amplifiers used in next-generation Gbaud transmission systems.

Televisions, telephones, watches, calculators, robots, airplanes and space vehicles all depend on silicon chips. Life as we know it would hardly be possible without semiconductor devices. An understanding of how these devices work requires a detailed knowledge of the physics of semiconductors, including charge transport and the emission and absorption of electromagnetic waves. This book may serve both as a university textbook and as a reference for research and microelectronics engineering. Each section of the book begins with a description of an experiment. The theory is then developed as far as necessary to understand the experimental results. Everyone with high-school mathematics should be able to follow the calculations. The band structure calculations for the diamond and zinc blende types of lattice are supplemented with a personal computer program. Semiconductor physics developed most rapidly in the two decades following the invention of the transistor, and naturally most of the references date from this time. But recent developments such as the Gunn effect, the acoustoelectric effect, superlattices, quantum well structures, and the quantum Hall effect are also discussed. The exercises provided (answers to which are available) will greatly assist the student in consolidating the material presented. From the reviews:"This book is a must for any theoretical and experimental physicist working in the area of semiconductor physics." #Physicalia#1

L'ultimo e più intenso romanzo di Cesare Pavese, pubblicato nell'aprile del 1950, pochi mesi prima della sua morte. La storia di un ritorno in Italia dopo la guerra e la liberazione, un intreccio fra presente e passato alla ricerca delle proprie radici e della propria identità.

"I Thibault" è una saga familiare di Roger Martin du Gard, composta da otto volumi pubblicati tra il 1922 e il 1940. È per questa opera che l'autore riceve il Premio Nobel per la letteratura nel novembre del 1937. Attraverso la vita di due famiglie borghesi, i Thibault e i Fontanin, è rappresentata la società francese della Belle Époque, destinata a finire tragicamente con la Prima guerra mondiale. L'intero ciclo è incentrato principalmente sui figli del notabile cattolico Oscar Thibault, due fratelli apparentemente agli antipodi.

In recent years the mathematical modeling of charge transport in semi­ conductors has become a thriving area in applied mathematics. The drift diffusion equations, which constitute the most popular model for the simula­ tion of the electrical behavior of semiconductor devices, are by now mathe­ matically quite well understood. As a consequence numerical methods have been developed, which allow for reasonably efficient computer simulations in many cases of practical relevance. Nowadays, research on the drift diffu­ sion model is of a highly specialized nature. It concentrates on the explora­ tion of possibly more efficient discretization methods (e.g. mixed finite elements, streamline diffusion), on the improvement of the performance of nonlinear iteration and linear equation solvers, and on three dimensional applications. The ongoing miniaturization of semiconductor devices has prompted a shift of the focus of the modeling research lately, since the drift diffusion model does not account well for charge transport in ultra integrated devices. Extensions of the drift diffusion model (so called hydrodynamic models) are under investigation for the modeling of hot electron effects in submicron MOS-transistors, and supercomputer technology has made it possible to employ kinetic models (semiclassical Boltzmann-Poisson and Wigner­ Poisson equations) for the simulation of certain highly integrated devices.

Lasers, having proven useful in such diverse areas as high­ resolution spectroscopy and the guiding of ferryboats, are cur­ rently enjoying great popularity among materials scientists and engineers. As versatile sources of "pure" energy in a highly concentrated form, lasers have become attractive tools and re­ search instruments in metallurgy, semiconductor technology and engineering. This text treats, from a physicist's point of view, some of the processes that lasers can induce in materials. The field of laser-material interactions is inherently mul­ tidisciplinary. Upon impact of a laser beam on a material, electromagnetic energy is converted first into electronic exci­ tation and then into thermal, chemical and mechanical energy. In the whole process the molecular structure as well as the shape of the material are changed in various ways. Understand­ ing this sequence of events requires knowledge from several branches of physics. A unified presentation of the subject, for the benefit of the materials researcher as well as the advanced student, is attempted here. In order to keep the book reason­ ably trim, I have focused on laser effects in solids such as thin films and technological materials. Related topiCS not cov­ ered are laser-induced chemical reactions in gases and liquids and laser effects in organic or biological materials.

The assembly of electronic circuit boards has emerged as one of the most significant growth areas for robotics and automated assembly. This comprehensive volume, which is an edited collection of material mostly published in "Assembly Engineering" and "Electronic Packaging and Production", will provide an essential reference for engineers working in this field, including material on Multi Layer Boards, Chip-on-board and numerous case studies. Frank J. Riley is senior vice-president of the Bodine Corporation and a world authority on assembly automation.

The publication of Introduction to Robotics is one among the results of many years' work by the authors of this book in the study of robotics. During the first stage of this work, devoted to locomotion robots and anthropomorphic mechanisms in particular, a number of papers were published in the period 1974-76. The most prominent of them is M. VukobratoviC's Legged Locomotion Systems and Anthropomorphic Mechanisms, published in English, Russian, Japanese and Chinese.
