Excerpt from The Bell System Technical Journal, 1949, Vol. 28: A Journal Devoted to the Scientific and Engineering Aspects of Electrical Communication When the discriminant is much smaller than one, most of the energy can be carried in one line or component mode. When the discriminant is much larger than one, the energy flow is nearly equally divided between the two lines or component modes. In wave guides of typical dimensions the coupling discriminant becomes one for a critical bending radius greater than a mile. For all sharper bends, that is for most practical installations, the discriminant is greater than one. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The first edition of this award-winning book attracted a wide audience. This second edition is both a joy to read and a useful classroom tool. Unlike traditional textbooks, it requires no mathematical prerequisites and can be read around the mathematics presented. If used as a textbook, the mathematics can be prioritized, with a book both students and instructors will enjoy reading. Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field. FEATURES Presents a chronological development of key concepts Includes the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s wheel cipher, Playfair cipher, ADFGX, matrix encryption, Enigma, Purple, and other classic methods Looks at the work of Claude Shannon, the origin of the National Security Agency, elliptic curve cryptography, the Data Encryption Standard, the Advanced Encryption Standard, public-key cryptography, and many other topics New chapters detail SIGABA and SIGSALY, successful systems used during World War II for text and speech, respectively Includes quantum cryptography and the impact of quantum computers

This eighteenth volume in the Poincaré Seminar Series provides a thorough description of Information Theory and some of its most active areas, in particular, its relation to thermodynamics at the nanoscale and the Maxwell Demon, and the emergence of quantum computation and of its counterpart, quantum verification. It also includes two introductory tutorials, one on the fundamental relation between thermodynamics and information theory, and a primer on Shannon's entropy and information theory. The book offers a unique and manifold perspective on recent mathematical and physical developments in this field.

This book states that a space-induced crisis is recognized as the cause of trouble that Moore’s Law is currently facing. The contemporary practice of this empirical law can be considered as happening within a space-dominant paradigm. An alternative of exploiting potential in the dimension of time is identified as an emerging paradigm in microelectronics. The new practice is termed a time-oriented paradigm. It is justified as the turn of Moore’s Law from space to time. The resultant Time-Moore strategy is envisioned as the next-generation enabler for continuing Moore’s Law’s pursuit of everhigher information processing power and efficiency. It also serves as the perpetuation of the spirit that Moore’s law is nothing but a collective storied history of innovations. In the first part of this book, by following Thomas Kuhn’s seminal work around the concepts of paradigm and scientific revolution, the argument for the Time-Moore strategy (Time-Moore: to use time more) and the paradigm shift from space to time is carried out heavily through philosophical persuasion rather than technical proof due to the difficult challenge of change-of-mindset. The second part of the book provides solid technical materials for supporting this transition from the old paradigm to the new one. In short, the goal of this book is to reevaluate the contemporary practice of microelectronics, identify the cause of the current crisis, advocate a change-of-mindset to circumvent the crisis, and ultimately point out a new route for advancing. After achieving so many unprecedented accomplishments through several decades of relentless endeavor, it’s time for the big ship of Moore’s Law (i.e., the art of microelectronic system design) to make a turn.

Following an exchange of correspondence, I met Ross in Adelaide in June 1988. I was approached by the University of Adelaide about being an external examiner for this dissertation and willingly agreed. Upon receiving a copy of this work, what struck me most was the scholarship with which Ross approaches and advances this relatively new field of adaptive data compression. This scholarship, coupled with the ability to express himself clearly using figures, tables, and incisive prose, demanded that Ross's dissertation be given a wider audience. And so this thesis was brought to the attention of Kluwer. The modern data compression paradigm furthered by this work is based upon the separation of adaptive context modelling, adaptive statistics, and arithmetic coding. This work offers the most complete bibliography on this subject I am aware of. It provides an excellent and lucid review of the field, and should be equally as beneficial to newcomers as to those of us already in the field.

The present “Solar Energy” science book hopefully opens a series of other first-hand texts in new technologies with practical impact and subsequent interest. They might include the ecological combustion of fossil fuels, space technology in the benefit of local and remote communities, new trends in the development of secure Internet Communications on an interplanetary scale, new breakthroughs in the propulsion technology and others. The editors will be pleased to see that the present book is open to debate and they will wait for the readers’ reaction with great interest. Critics and proposals will be equally welcomed.
