physica status solidi (c) conferences and critical reviews publishes conference proceedings, ranging from large international meetings to specialized topical workshops as well as collections of topical reviews on various areas of current solid state physics research. The objective of "Optics of Surfaces and Interfaces" (OSI-V) is to bridge the gap between basic and applied science. Apart from recent advances in theoretical modeling and experimental research, special attention is given to novel techniques of optical spectroscopy at interfaces.
This edition reflects the latest networking technologies with a special emphasis on wireless networking, including 802.11, 802.16, Bluetooth, and 3G cellular, paired with fixed-network coverage of ADSL, Internet over cable, gigabit Ethernet, MPLS, and peer-to-peer networks. It incorporates new coverage on 3G mobile phone networks, Fiber to the Home, RFID, delay-tolerant networks, and 802.11 security, in addition to expanded material on Internet routing, multicasting, congestion control, quality of service, real-time transport, and content distribution.
Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.
This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. Computer Security: Principles and Practice, 2e, is ideal for courses in Computer/Network Security. In recent years, the need for education in computer security and related topics has grown dramatically – and is essential for anyone studying Computer Science or Computer Engineering. This is the only text available to provide integrated, comprehensive, up-to-date coverage of the broad range of topics in this subject. In addition to an extensive pedagogical program, the book provides unparalleled support for both research and modeling projects, giving students a broader perspective. The Text and Academic Authors Association named Computer Security: Principles and Practice, 1e, the winner of the Textbook Excellence Award for the best Computer Science textbook of 2008.
Digital technologies are spreading rapidly, but digital dividends--the broader benefits of faster growth, more jobs, and better services--are not. If more than 40 percent of adults in East Africa pay their utility bills using a mobile phone, why can’t others around the world do the same? If 8 million entrepreneurs in China--one third of them women--can use an e-commerce platform to export goods to 120 countries, why can’t entrepreneurs elsewhere achieve the same global reach? And if India can provide unique digital identification to 1 billion people in five years, and thereby reduce corruption by billions of dollars, why can’t other countries replicate its success? Indeed, what’s holding back countries from realizing the profound and transformational effects that digital technologies are supposed to deliver? Two main reasons. First, nearly 60 percent of the world’s population are still offline and can’t participate in the digital economy in any meaningful way. Second, and more important, the benefits of digital technologies can be offset by growing risks. Startups can disrupt incumbents, but not when vested interests and regulatory uncertainty obstruct competition and the entry of new firms. Employment opportunities may be greater, but not when the labor market is polarized. The internet can be a platform for universal empowerment, but not when it becomes a tool for state control and elite capture. The World Development Report 2016 shows that while the digital revolution has forged ahead, its 'analog complements'--the regulations that promote entry and competition, the skills that enable workers to access and then leverage the new economy, and the institutions that are accountable to citizens--have not kept pace. And when these analog complements to digital investments are absent, the development impact can be disappointing. What, then, should countries do? They should formulate digital development strategies that are much broader than current information and communication technology (ICT) strategies. They should create a policy and institutional environment for technology that fosters the greatest benefits. In short, they need to build a strong analog foundation to deliver digital dividends to everyone, everywhere.
In this unique volume, an international cast of leading scholars from several disciplines offers a comprehensive assessment of the current status of space-based weaponry. Regional and technical experts offer their analysis of the major powers' special interests in space and also examine the broader issues of ICBM proliferation, testing, monitoring, and verification as well as possible opportunities for cooperation between states with a stake in space power.
Now the standardisation work of DAB (Digital Audio Broadcasting)system is finished many broadcast organisations, network providersand receiver manufacturers in European countries and outside ofEurope (for example Canada and the Far East) will be installing DABbroadcast services as pilot projects or public services. Inaddition some value added services (data and video services) areunder development or have already started as pilot projects. The new digital broadcast system DAB distinguishes itself fromexisting conventional broadcast systems, and the various newinternational standards and related documents (from ITU-R, ISO/IEC,ETSI, EBU, EUREKA147, and others) are not readily available and aredifficult to read for users. Therefore it is essential that a wellstructured technical handbook should be available. The Second Edition of Digital Audio Broadcasting has beenfully updated with new sections and chapters added to reflect allthe latest developments and advances. Digital Audio Broadcasting: Provides a fully updated comprehensive overview of DAB Covers international standards, applications and othertechnical issues Combines the expertise of leading researchers in the field ofDAB Now covers such new areas as: IP-Tunneling via DAB; ElectronicProgramme Guide for DAB; and Metadata A comprehensive overview of DAB specifically written forplanning and system engineers, developers for professional anddomestic equipment manufacturers, service providers, as well aspostgraduate students and lecturers in communicationstechnology.
