Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
Download or read book OFDM for Underwater Acoustic Communications written by Sheng Zhou and published by John Wiley & Sons. This book was released on 2014-03-21 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: A blend of introductory material and advanced signal processing and communication techniques, of critical importance to underwater system and network development This book, which is the first to describe the processing techniques central to underwater OFDM, is arranged into four distinct sections: First, it describes the characteristics of underwater acoustic channels, and stresses the difference from wireless radio channels. Then it goes over the basics of OFDM and channel coding. The second part starts with an overview of the OFDM receiver, and develops various modules for the receiver design in systems with single or multiple transmitters. This is the main body of the book. Extensive experimental data sets are used to verify the receiver performance. In the third part, the authors discuss applications of the OFDM receiver in i) deep water channels, which may contain very long separated multipath clusters, ii) interference-rich environments, where an unintentional interference such as Sonar will be present, and iii) a network with multiple users where both non-cooperative and cooperative underwater communications are developed. Lastly, it describes the development of a positioning system with OFDM waveforms, and the progress on the OFDM modem development. Closely related industries include the development and manufacturing of autonomous underwater vehicles (AUVs) and scientific sensory equipment. AUVs and sensors in the future could integrate modems, based on the OFDM technology described in this book. Contents includes: Underwater acoustic channel characteristics/OFDM basics/Peak-to-average-ratio control/Detection and Doppler estimation (Doppler scale and CFO)/Channel estimation and noise estimation/A block-by-block progressive receiver and performance results/Extensions to multi-input multi-output OFDM/Receiver designs for multiple users/Cooperative underwater OFDM (Physical layer network coding and dynamic coded cooperation)/Localization with OFDM waveforms/Modem developments A valuable resource for Graduate and postgraduate students on electrical engineering or physics courses; electrical engineers, underwater acousticians, communications engineers

The authors then propose cross layer networking solutions to achieve a high performance modern MWCN that enables efficient and reliable data transmissions under hostile marine environment, which include the network deployment, the physical layer channel coding, intelligent network access and resource management, and learning-based opportunistic routing. Finally, the authors summarize the book and present some open issues that will lead to new research directions in the next generation MWCNs.
Download or read book The New Communications Technologies written by Michael Mirabito and published by Taylor & Francis. This book was released on 2004-03-23 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: As new communications applications are developed and brought to market, it is vital for communications professionals to keep abreast of these issues. Since the technologies and applications also affect our daily lives, it is important to understand how they will shape the country and, by extension, the world at large. International censorship, the impact of the Internet and wireless tools, and th legisation following the World Trade Center bombing all fall into this category. The New Communications Technologies, Fifth Edition, provides vital information on the new and emerging technologies that will shape the way communicators do business. The book explores the new communications technologies and covers topics ranging from multimedia and production to satellites to digital communication. Just as important, the book examines the social, economic, and political impact brought about by the adoption of such technologies and applications; this fallout includes privacy concerns, First Amendment issues, and the implications raised by biometric systems.
Download or read book Communications Standard Dictionary written by Martin H. Weik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communications * Standard Dictionary is a comprehensive compilation of terms and definitions used in communications and related fields. Communications is defined as the branch of science and technology concerned with the process of representing, transferring, and interpreting the meaning as signed to data by and among persons, places, or machines. Communication is defined as the transfer of information between a source (trans mitter, light source) and a sink (receiver, photodetector) over one or more chan nels in accordance with a protocol, and in a manner suitable for interpretation or comprehension by the receiver; or as a method or means of conveying informa tion of any kind from one person or place to another. In short, communications is a branch of science and technology, whereas com munication pertains to the actual transfer of information. Thus, the word com munication should be used as a modifier, as in communication center, communi cation deception, and communication line, just as in the field of electronics one speaks of electronic devices and electronic circuits.
