-WDM Technologies: Optical Networks by Achyut K. Dutta , Niloy K. Dutta , Masahiko Fujiwara

Internet information (which is doubling every six months) travels through optical fibers. Today, optical fibers are being installed where a single fiber has the ability to carry information as much as 200 times faster than was possible just five years ago. This revolutionary capability is being achieved with technology known as wavelength division multiplexing WDM). WDM technology relies on the fact that optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength. Thus, a single fiber can carry many separate wavelength signals or channels simultaneously.The communications industry is at the onset of new expansion of WDM technology necessary to meet the new demand for bandwidth. WDM Technologies: Optical Networks deals with the Networks facet of this field (present and future). Allows engineers working in optical communications(from systems to components) to understand the principles and mechanics of each key component they deal with for optical system design Provides an excellent resource for engineers and researchers engaged in all aspects of fiber optic communications, such as optoelectronics, equipment/system design, and manufacturing Provides comprehensive coverage of key concepts in optical networks and their application in commercial systems ...

The Buddha: A Very Short Introduction by Carrithers, Michael

Library

There is a whole series of the Past Masters books but this is the first one I have read (The Buddha: Past Masters by Michael Carrithers) in this series. I have been interested in the many Asian philosophies for most of my life and I have read numerous books on the topic over the years.This 102 page hardcover volume focuses on the life and intellectual development of the Buddha. It explains the differences and similarities of various competing philosophies being promoted at the time. This book is organized into five sections. The introduction provides insight into some of the myths surrounding this historical figure. The second section covers in detail the early life and renunciation. The third and fourth section deals with the awakening. The final chapter explains the mission and the death of Buddha. There is also a section on further readings about the Buddha.Though this book did a great job of explaining the thought process and life of this great philosopher I was a little disappointed that there were so few quotes from the Buddha in this volume. Nevertheless, I think anyone interested in the life of the Buddha will find this a good introduction to the topic....

Borders: A Very Short Introduction by Alexander C. Diener , Joshua Hagen

Library

ompelling and accessible, this Very Short Introduction challenges the perception of borders as passive lines on a map, revealing them instead to be integral forces in the economic, social, political, and environmental processes that shape our lives. Highlighting the historical development and continued relevance of borders, Alexander C. Diener and Joshua Hagen offer a powerful counterpoint to the idea of an imminent borderless world, underscoring the impact borders have on a range of issues, such as economic development, inter- and intra-state conflict, global terrorism, migration, nationalism, international law, environmental sustainability, and natural resource management. Diener and Hagen demonstrate how and why borders have been, are currently, and will undoubtedly remain hot topics across the social sciences and in the global headlines for years to come. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable....

Communication Networking: An Analytical Approach by Kumar

Library

Key Features Systematically uses mathematical models and analyses to drive the development of a practical understanding of core network engineering problems. Provides in-depth coverage of many current topics, including network calculus with deterministically-constrained traffic, congestion control for elastic traffic, packet switch queuing, switching architectures, virtual path routing, and routing for quality of service. Includes over 200 hands-on exercises and class-tested problems, dozens of schematic figures, a review of key mathematical concepts, and a glossary. Description The viewpoint is that communication networking is about efficient resource sharing. The focus is on the three building blocks of communication networking, namely, multiplexing, switching and routing. The approach is analytical, with the discussion being driven by mathematical analyses of and solutions to specific engineering problems. The result? A comprehensive, effectively organized treatment of core engineering issues in communication networking. Written for both the networking professional and for the classroom, this book covers fundamental concepts in detail and places design issues in context by drawing on real world examples from current technologies. Readership PROFESSIONAL REFERENCE: Networking professionals whose work is primarily architecture definition and implementation, i.e., network engineers and designers at telecom companies, industrial research labs, etc. ACADEMIC: Final year undergrad and first year graduate students in EE, CE, and CS programs. Quotes This book combines an innovative and uniform representation of a variety of communication networks, simple to understand motivations for real design problems for these networks, intuitive approaches to solutions, and rigorous mathematical analysis where appropriate. It will be very valuable both as a textbook and as a reference for practitioners. --Bharat Doshi, Director of Transformational Communication, Johns Hopkins. ...

Chemistry: A Very Short Introduction by Peter Atkins

Library

Most people remember chemistry from their schooldays as largely incomprehensible, a subject that was fact-rich but understanding-poor, smelly, and so far removed from the real world of events and pleasures that there seemed little point, except for the most introverted, in coming to terms with its grubby concepts, spells, recipes, and rules. Peter Atkins wants to change all that.In this Very Short Introduction to Chemistry, he encourages us to look at chemistry anew, through a chemist's eyes, in order to understand its central concepts and to see how it contributes not only towards our material comfort, but also to human culture. Atkins shows how chemistry provides the infrastructure of our world, through the chemical industry, the fuels of heating, power generation, and transport, as well as the fabrics of our clothing and furnishings.By considering the remarkable achievements that chemistry has made, and examining its place between both physics and biology, Atkins presents a fascinating, clear, and rigorous exploration of the world of chemistry - its structure, core concepts, and exciting contributions to new cutting-edge technologies.

Developing User Interfaces by Dan R. Olsen

Library

In the early days of computing, technicians in white coats controlled refrigerator-sized computers housed in sealed rooms, far from ordinary users. Today, computers are inexpensive commodities, like television sets,and ordinary people control and interact with them. This new paradigm has led to a burgeoning demand for graphics-intensive and highly interactive interfaces.Developing User Interfaces is targeted at the programmer who will actually implement, rather than design, the user interface. Most user interface books focus on psychology and usability, not programming techniques. This book recognizes the need for programmers to collaborate with usability experts and psychologists, so topics such as the principles of visualization, human perception, and usability evaluation are touched upon. Yet the primary focus remains on those tools and techniques required for programming the complex user interface. * Focuses on advanced programming topics * event handling * interaction with geometric objects * widget tool kits * input syntax * Useful to programmers using any language―no particular windowing system or tool kit is presumed, examples are drawn from a variety of commercial systems, and code examples are presented in pseudo code * The basic concepts of traditional computer graphics such as drawing and three-dimensional modeling are covered for readers without a computer graphics background....
