The original essays in this collection ground the shifting terrain of feminism in the 21st century. The contributors define and examine the complexity of the Third Wave by answering questions like: how appropriate is a "third wave" label for contemporary feminism; are the agendas of contemporary feminism and the "second wave" really all that different; does the wave metaphor accurately describe the difference between contemporary feminists and their predecessors; how do women of color fit into this notion of contemporary feminism; and what are the future directions of the feminist movement?
Contains 110,000 wavelength entries from the 1939 edition with corrections or changes indicated by a line through the entry. Read the introduction to the 1969 edition for further explanation. Wavelengths in the range of 10,000-2,000 A are covered.
Explaining what CWDM is, how it is achieved, and why it should be deployed, Coarse Wavelength Division Multiplexing: Technologies and Applications merges coverage of isolated aspects of Coarse Wavelength Division Multiplexing (CWDM) traditionally found as device-related or specific system topics. Emphasizing cost savings and performance enhancement, the book integrates information on component issues, system architectures, concepts for extensions and upgrades, as well as practical applications into a comprehensive, single-volume resource. Beginning with a summary of the ITU-T standards defining CWDM, the book addresses the three essential component classes, optical fibers, transceivers, and WDM filters, which combine to form the basis for the CWDM transmission link. The following chapters include coverage of different architectures such as hubbed rings and meshed networks, and upgrade paths to overcome limitations of current CWDM systems. The book outlines the feasibility of optically amplified CWDM systems, investigates the challenges present with high-speed CWDM and bidirectional transmission, and finally elucidates the importance of CWDM for a wide range of applications. Each chapter provides sufficient information to be used independently and contains references to relevant papers and articles for further study. The last sections of the book focus on applications and case studies where CWDM plays an ever-increasing role. They include extensive studies on networking, reach extension by amplification, and the latest concepts of transmission capacity upgrades using increased bit-rates or new channel plans. Filled with practical information, the book provides a clear understanding of recent developments in the dynamic field of CWDM.
This book focuses on methods for service-differentiated and constraint-based wavelength routing and resource allocation for multi-service WDM networks. A number of unique routing solutions are proposed, and an extensive analysis of dynamically re-configurable multi-service WDM networks impart the major contribution to the current efforts in standardisation and network operation.
Short-wavelength magnetic recording presents a series of practical solutions to a wide range of problems in the field of magnetic recording. It features many new and original results, all derived from fundamental principles as a result of up-to-date research. A special section is devoted to the playback process, including the calculations of head efficiency and head impedance, derived from new theorems. Features include: A simple and fast method for measuring efficiency; a simple method for the accurate separation of the read and write behaviour of magnetic heads; a new concept - the bandpass head. Other types of head covered include: the metal-in-gap head; the amarphous head; the thin-film head; the magneto-resistive head; and probe-type heads for perpendicular recording. The introduction includes an invaluable historical summary of magnetic recording, and the book also features an extensive subject index, complete author index, and a glossary of symbols. "The scope and mathematical rigour of this book can only be compared with W.K. Westmijze's 1953 landmark "Studies in Magnetic Recording" "The easy writing style (renders) the mathematical treatments readily understandable as physical propositions... A careful study of this book cannot help but provide the reader with the most profound insights into the limits of short-wavelength recording." John C. Mallinson, Center for Magnetic Recording Research, University of California, San Diego, USA.
These Proceedings present the most recent results from the highly successful international solar space missions (SOHO, CORONAS-F, TRACE, RHESSI, YOHKOH) and ground observatories around the Earth, reported at the IAU Symposium 223 held in St. Petersburg, Russia, June 14-19, 2004. These include discussions of the current theories of solar dynamics and activity, new constraints provided by the multi-wavelength observations of the Sun from the interior to the heliosphere, as well as discussions of future coordinated plans and efforts of multi-wavelength investigations of the Sun. The Proceedings contain the material of seven plenary sessions and three round-table discussions
Author Dennett Berg Nelson was born during an era when traditional explanations for any type anomaly were not to be challenged. As an amateur in science, theology and the paranormal however, he has always looked for more reasonable and understandable explanations for solving age-old mysteries; and this writing provides a simple common denominator by which we can easily interpret those longstanding unknowns. Today Dennett Berg is a popular visionary. His first book, The Tunlight Report, solved many major catastrophes, especially the type disasters for which the governments explanations were doubtful at best. This book, Have WAVELENGTH, Will Travel, outlines how wavelengths hold the key for travel into other dimensions. Once the key is turned and the travel door is open, we: Learn how God created the Big Bang, Heaven and Earth Learn the answer to, Which came first, the chicken or the egg? Learn how Noah lived for 950 years Learn how ghosts exist and how to rid yourself of the pesky ones Learn how aliens, and their UFOs, are neighbors, not extraterrestrials Learn how most of us have experienced time travel but didnt know it Learn how we access Heaven and Eternal Life. Dennett Bergs research into parallel universes and time travel are condensed into this guide for out of this world travel.
