The Art of Error Correcting Coding provides a comprehensive coverage of the basic techniques of error concealment. It addresses the need for selecting, implementing and simulating algorithms for the encoding and decoding of codes used for error correction and detection. This practical approach uses simple and easy to follow numerical examples to describe the basic concepts of a particular coding or decoding scheme. Basic analysis tools are provided throughout to help in the assessment of the error performance block and convolutional codes of a particular Error Correcting Coding (ECC) scheme for a selection of the basic channel models.

Nanotechnology, or molecular technology, involves the manipulation of individual atoms and molecules, something the human body already does.In Engines of Creation , Drexler attempts to predict, justify, quantify, and caution us about this important new field in engineering. His book could have been the first and foremost discussion of this fascinating subject. But Drexler strays from the topic with annoying regularity. He devotes too little space to the possibilities of nanotechnology and too much to esoteric and opinionated discussions of philosophy, politics, information science, defense, human relations, etc. Nanotechnology will indeed become a reality, and the public needs to be informed. It is therefore unfortunate that Engines of Creation was not written more clearly or directly. Kurt O. Baumgartner, International Minerals & Chemical
This brilliant work heralds the new age of nanotechnology, which will give us thorough and inexpensive control of the structure of matter. Drexler examines the enormous implications of these developments for medicine, the economy, and the environment, and makes astounding yet well-founded projections for the future.

Much of the business transacted on the Web today takes place through information exchanges made possible by using documents as interfaces. For example, what seems to be a simple purchase from an online bookstore actually involves at least three different business collaborations — between the customer and the online catalog to select a book; between the bookstore and a credit card authorization service to verify and charge the customer’s account; and between the bookstore and the delivery service with instructions for picking up and delivering the book to the customer. Document engineering is needed to analyze, design, and implement these Internet information exchanges. This book is an introduction to the emerging field of document engineering.
The authors, both leaders in the development of document engineering and other e-commerce initiatives, analyze document exchanges from a variety of perspectives. Taking a qualitative view, they look at patterns of document exchanges as components of business models; looking at documents in more detail, they describe techniques for analyzing individual transaction patterns and the role they play in the overall business process. They describe techniques for analyzing, designing, and encoding document models, including XML, and discuss the techniques and architectures that make XML a unifying technology for the next generation of e-business applications. Finally, they go beyond document models to consider management and strategic issues — the business model, or the vision, that the information exchanged in these documents serves.
A unique system focus that presents specific solutions for specific
appliances This publication presents state-of-the-art power management
techniques for modern electronic appliances that rely on such very
large-scale integration (VLSI) chips as CPUs and DSPs. The author
thoroughly covers all aspects of the field, including semiconductor
manufacturing processes, packages, circuits, functions, and systems. A
unique and significant contribution to the field, the publication
adopts a “system focus” by first presenting the appliance and then
delving into the power management architecture and topologies that best
serve each appliance. In addition to specific techniques and
applications, the publication discusses fundamental physical and
socioeconomic issues. For example, the author examines Moore’s law and
its effect on power management and heat dissipation, which points to a
future breakthrough needed to continue the fast pace of advancement in
the high-tech industry. The author provides a solid technical
foundation and an analysis of popular electronic appliances, including:
Overview of the semiconductor industry Plain-English discussion of
semiconductor processes and packages Step-by-step guide to analog
design building from the transistor to higher-level functions, leading
to the implementation of a complete voltage regulator Popular DC-DC
voltage regulation architectures AC-DC architectures for power
conversion Ultra-portable devices, such as cellular phones, PDAs, and
digital still cameras Desktop and notebook PCs The publication
