Noise Tolerant Data Authentication for Wireless Communication (Signals And Communication Technology)
by Natasa Zivic Obaid Ur-RehmanThis book provides insight into the challenges in providing data authentication over wireless communication channels. The authors posit that established standard authentication mechanisms – for wired devices – are not sufficient to authenticate data, such as voice, images, and video over wireless channels. The authors propose new mechanisms based on the so-called soft authentication algorithms, which tolerate some legitimate modifications in the data that they protect. The authors explain that the goal of these algorithms is that they are tolerant to changes in the content but are still able to identify the forgeries. The authors go on to describe how an additional advantage of the soft authentication algorithms is the ability to identify the locations of the modifications and correct them if possible. The authors show how to achieve this by protecting the data features with the help of error correcting codes. The correction methods are typically based on watermarking, as the authors discuss in the book.Provides a discussion of data (particularly image) authentication methods in the presence of noise experienced in wireless communication;Presents a new class of soft authentication methods, instead of the standard hard authentication methods, used to tolerate minor changes in image data;Features authentication methods based on the usage of authentication tags as well as digital watermarks.

Non-Line-of-Sight Ultraviolet Communications: Principles and Technologies (SpringerBriefs in Computer Science)
by Renzhi Yuan Zhifeng WangThis book provides a comprehensive review and the latest progress of ultraviolet communications. Optical wireless communications employing electromagnetic waves in optical wavebands as information carriers can achieve higher communication bandwidth compared with radio frequency based wireless communication. However, the good directionality of optical waves degrades its non-line-of-sight transmission ability for avoiding obstacles. The ultraviolet communication employs the ultraviolet light in “solar blind” waveband (200–280 nm) as information carriers. The name “solar blind" is derived from the fact that the solar radiation in 200–280 nm is strongly absorbed by the ozone layer of the atmosphere such that little ultraviolet lights can reach the earth's surface. Therefore, ultraviolet communications enjoy low background radiation noise compared with other optical wireless communications. Besides, the strong absorption effect of ultraviolet lights in the atmosphere also guarantees a good local security due to the verified low-probability-of-detection. Therefore, the ultraviolet communication becomes a promising non-line-of-sight optical wireless communication technology and attracted increasing research attentions in recent decades. This book mainly focuses on the key principles and technologies of ultraviolet communications, including the channel modeling, achievable information rate, full-duplex ultraviolet communication, relay-assisted ultraviolet communication, non-line-of-sight ultraviolet positioning, and some future prospects of ultraviolet communications.

Non-Western Perspectives on Human Communication: Implications for Theory and Practice
by Dr Min-Sun KimWhat it means to be a self - and a self communicating and being in a particular culture - are key issues interwoven throughout Min-Sun Kim's impressive text, Non-Western Perspectives on Human Communication. Going beyond cultural descriptions or instructions on adapting to specific cultures, the author interrogates the very core assumptions underlying the study of human communication and challenges longstanding individualistic, Western models on which much intercultural research is based. Kim proposes a non-western way of conceptualizing identity, or the "self" - the cornerstone of cultural research -- illuminating how traditional western and non-western views can be blended into a broader, more realistic understanding of cultures and communication. Grounding her work in a thorough knowledge of the literature, she challenges students and researchers alike to reexamine their approach to intercultural study.
Nonlinear Aspects of Telecommunications: Discrete Volterra Series and Nonlinear Echo Cancellation (Electronic Engineering Systems)
by Andrzej BorysThe discrete Volterra series holds particular value in the analysis of nonlinear systems in telecommunications. However, most books on the Volterra series either do not address this application or only offer a partial discussion. Nonlinear Aspects of Telecommunications provides an in-depth treatment of the Volterra series and the benefits it offers as a representation of nonlinear problems, particularly in echo cancellation in digital telecommunications systems.Beginning with the fundamentals of the discrete Volterra series, the author presents its basic definition, notions, conditions for convergence and stability, and its matrix representation for multiple-input and multiple-output nonlinear digital systems. He pays significant attention to the important problem of approximating a nonlinear digital system using the discrete Volterra series and offers new results in this area--results not yet available in other texts.The second part of the book uses the background of Part I to show the Volterra series' application to echo cancellation. It provides introductory material regarding the basics of adaptive cancellers, and analyzes structures for nonlinear echo cancellers using nonlinear transversal filters for baseband transmission. The last section covers nonlinear echo cancellers for voiceband transmission and interleaved structures.Full of illustrations, examples, and new results, Nonlinear Aspects of Telecommunications is your first and best resource for understanding and applying the discrete Volterra series to nonlinear echo cancellation problems.Features

Nonlinear Power Flow Control Design
by Rush D. Robinett III David G. WilsonThis book presents an innovative control system design process motivated by renewable energy electric grid integration problems. The concepts developed result from the convergence of research and development goals which have important concepts in common: exergy flow, limit cycles, and balance between competing power flows. A unique set of criteria is proposed to design controllers for a class of nonlinear systems. A combination of thermodynamics with Hamiltonian systems provides the theoretical foundation which is then realized in a series of connected case studies. It allows the process of control design to be viewed as a power flow control problem, balancing the power flowing into a system against that being dissipated within it and dependent on the power being stored in it - an interplay between kinetic and potential energies. Human factors and the sustainability of self-organizing systems are dealt with as advanced topics.
Nonlinear Stochastic Systems with Incomplete Information
by Huisheng Shu Zidong Wang Bo ShenNonlinear Stochastic Processes addresses the frequently-encountered problem of incomplete information. The causes of this problem considered here include: missing measurements; sensor delays and saturation; quantization effects; and signal sampling. Divided into three parts, the text begins with a focus on H filtering and control problems associated with general classes of nonlinear stochastic discrete-time systems. Filtering problems are considered in the second part, and in the third the theory and techniques previously developed are applied to the solution of issues arising in complex networks with the design of sampled-data-based controllers and filters. Among its highlights, the text provides: * a unified framework for filtering and control problems in complex communication networks with limited bandwidth; * new concepts such as random sensor and signal saturations for more realistic modeling; and * demonstration of the use of techniques such as the Hamilton-Jacobi-Isaacs, difference linear matrix, and parameter-dependent matrix inequalities and sums of squares to handle the computational challenges inherent in these systems. The collection of recent research results presented in Nonlinear Stochastic Processes will be of interest to academic researchers in control and signal processing. Graduate students working with communication networks with lossy information and control of stochastic systems will also benefit from reading the book.

Nonrequired Reading
by Wislawa Szymborska Clare CavanaghWislawa Szymborska's poems are admired around the world, and her unsparing vision, tireless wit, and deep sense of humanity are cherished by countless readers. Unknown to most of them, however, Szymborska also worked for several decades as a columnist, reviewing a wide variety of books under the unassuming title "Nonrequired Reading." As readers of her poems would expect, the short prose pieces collected here are anything but ordinary. Reflecting the author's own eclectic tastes and interests, the pretexts for these ruminations range from books on wallpapering, cooking, gardening, and yoga, to more lofty volumes on opera and world literature. Unpretentious yet incisive, these charming pieces are on a par with Szymborska's finest lyrics, tackling the same large and small questions with a wonderful curiosity.

The Nonverbal Advantage: Secrets and Science of Body Language at Work
by Carol Kinsey GomanWhat are you saying when you&’re not speaking? A top consultant &“shows you how to use body language skills to build stronger professional relationships&” (Robert L. Dilenschneider, author of The Ultimate Guide to Power and Influence). How is the audience reacting to my presentation? Should I believe what my boss just told me? Is this person a potential buyer, or am I just wasting my time? How do I know if the CEO really supports my idea? Studies show that ninety-three percent of the messages people receive from us—and that we receive from them—have nothing to do with the words that are said. Therefore, strong nonverbal communication skills are a huge professional advantage, but until now little information has been available about how to hone the ability to use and interpret body language on the job. In The Nonverbal Advantage, Carol Kinsey Goman combines the latest research and her twenty-five years of practical experience as a consultant, coach, and therapist to offer a fun and practical guide to understanding what we and the people we work with are saying without speaking. While firmly grounded in recent discoveries in evolutionary psychology, neurobiology, sociology, criminology, anthropology, and communication studies, Goman&’s book is written in an informal, conversational tone and illustrates her points with cartoons, photos, and entertaining anecdotes. She also includes a chapter on translating body language across different cultures, and dozens of simple, enlightening exercises you can practice on and off the job—to gain control over the message you&’re sending.
