In their comprehensive new introduction to phonetics, Ball and Rahilly offer a detailed explanation of the process of speech production, from the anatomical initiation of sounds and their modification in the larynx, through to the final articulation of vowels and consonants in the oral and nasal tracts. This textbook is one of the few to give a balanced account of segmental and suprasegmental aspects of speech, showing clearly that the communication chain is incomplete without accurate production of both individual speech sounds (segmental features) and aspects such as stress and intonation (suprasegmental features). Throughout the book the authors provide advice on transcription, primarily using the International Phonetic Alphabet (IPA). Students are expertly guided from basic attempts to record speech sounds on paper, to more refined accounts of phonetic detail in speech. The authors go on to explain acoustic phonetics in a manner accessible both to new students in phonetics, and to those who wish to advance their knowledge of key pursuits in the area, including the sound spectrograph. They describe how speech waves can be measured, as well as considering how they are heard and decoded by listeners, discussing both physiological and neurological aspects of hearing and examining the methods of psychoacoustic experimentation. A range of instrumentation for studying speech production is also presented. The next link is acoustic phonetics, the study of speech transmission. Here the authors introduce the basic concepts of sound acoustics and the instrumentation used to analyse the characteristics of speech waves. Finally, the chain is completed by examining auditory phonetics, and providing a fascinating psychoacoustic experimentation, used to determine what parts of the speech signal are most crucial for listener understanding. The book concludes with a comprehensive survey and description of modern phonetic instrumentation, from the sound spectrograph to magnetic resonance imaging (MRI).

Streaming Media with Peer-to-Peer Networks: Wireless Perspectives offers insights into current and future communication technologies for a converged Internet that promises soon to be dominated by multimedia applications, at least in terms of bandwidth consumption. The book will be of interest to industry managers, and will also serve as a valuable resource to students and researchers looking to grasp the dynamic issues surrounding video streaming and wireless network development.
Optical communications networks are an essential part of the world wide te- communication infrastructure . The number of users of present and future telecommunication services like Internet, web browsing and tele-education is expected to increase dramatically . As a consequence there is an imminent - mand for high broadband and high capacity communication systems. A prom- ing solution is found in the concept of all-optical networks . These networks exploit the vast capacity of the optical fiber by using multiplexing techniques that allow for an overall capacity of terabits per second. Channels are routed and switched in the optical domain . In this manner data channels are carried from the receiver side to its destination making use of optical transmission techniques . Wavelength division multiplexing (WDM) is a transmission technique that has dramatically increased the capacity of optical transmission systems. WDM allows for transmission of several channels over a single optical fiber by - ing different wavelength as the channel carrier . Optical switching and routing techniques are also being developed to cope with the high data speeds and n- ber of channel carried in the optical fibers. These functionalities are provided by optical crossconnects. The use of transmission techniques such as WDM in combination with optical crossconnects is enabling optical networking at high bit-rates reaching terabits per second . These techniques also offer ways to improve the network flexibility and configurability .

The subject of error-control coding bridges several disciplines, in particular mathematics, electrical engineering and computer science. The theory of error-control codes is often described abstractly in mathematical terms only, for the benefit of other coding specialists. Such a theoretical approach to coding makes it difficult for engineers to understand the underlying concepts of error correction, the design of digital error-control systems, and the quantitative behavior of such systems. In this book only a minimal amount of mathematics is introduced in order to describe the many, sometimes mathematical, aspects of error-control coding. The concepts of error correction and detection are in many cases sufficiently straightforward to avoid highly theoretical algebraic constructions. The reader will find that the primary emphasis of the book is on practical matters, not on theoretical problems. In fact, much of the material covered is summarized by examples of real developments, and almost all of the error-correction and detection codes introduced are attached to related practical applications. Error-Control Coding for Data Networks takes a structured approach to channel-coding, starting with the basic coding concepts and working gradually towards the most sophisticated coding systems. The most popular applications are described throughout the book. These applications include the channel-coding techniques used in mobile communication systems, such as: the global system for mobile communications (GSM) and the code-division multiple-access (CDMA) system, coding schemes for High-Definition TeleVision (HDTV) system, the Compact Disk (CD), and Digital Video Disk (DVD), as well as theerror-control protocols for the data-link layers of networks, and much more. The book is compiled carefully to bring engineers, coding specialists, and students up to date in the important modern coding technologies. Both electrical engineering students and communication engineers will benefit from the information in this largely self-contained text on error-control system engineering.
Is information technology enhancing democracy? Developments in information technology and the Internet are taking place at an almost bewildering pace. Such improvements, however, are believed to present opportunities for improving the responsiveness and accountability of political institutions and enhancing citizen participation. In this text the theoretical arguments for and against "electronic democracy" and the potential of information and communication technology are closely examined. The book is underpinned by a series of case studies in the US and Europe that demonstrate the application of "electronic democracy" in a number of city and civic projects. The book aims to provide a balanced and considered evaluation of the potential for "electronic democracy" based on empirical research.
Following the emergence of quantum computing, the subsequent quantum revolution will be that of interconnecting individual quantum computers at the global level. In the same way that classical computers only realised their full potential with the emergence of the internet, a fully-realised quantum internet is the next stage of evolution for quantum computation. This cutting-edge book examines in detail how the quantum internet would evolve in practise, focusing not only on the technology itself, but also the implications it will have economically and politically, with numerous non-technical sections throughout the text providing broader context to the discussion. The book begins with a description of classical networks before introducing the key concepts behind quantum networks, such as quantum internet protocols, quantum cryptography, and cloud quantum computing. Written in an engaging style and accessible to graduate students in physics, engineering, computer science and mathematics.

The emerging paradigm of collaborative networked organizations
(CNOs), or simply collaborative networks, represents a dynamic and
multidisciplinary research and development area for which a number
of research results are available from many international and
national projects. A large number of practical application
experiments and pilot cases also provide evidence on what works and
what still remains as a challenge for CNOs. The fast evolution of
information and communication technologies and in particular the
so-called Internet technologies, also represents an important
motivator for the emergence of new forms of collaboration. There
is, however, an urgent need to start more consolidated and holistic
research strategies to support proper developments in this area.

Due to the great success and enormous impact of IP networks, In ternet access (such as sending and receiving e-mails) and web brows ing have become the ruling paradigm for next generation wireless systems. On the other hand, great technological and commercial success of services and applications is being witnessed in mobile wire less communications with examples of cellular, pes voice telephony and wireless LANs. The service paradigm has thus shifted from the conventional voice service to seamlessly integrated high quality mul timedia transmission over broadband wireless mobile networks. The multimedia content may include data, voice, audio, image, video and so on. With availability of more powerful portable devices, such as PDA, portable computer and cellular phone, coupled with the easier access to the core network (using a mobile device), the number of mobile users and the demand for multimedia-based applications is increasing rapidly. As a result, there is an urgent need for a sys tem that supports heterogeneous multimedia services and provides seamless access to the desired resources via wireless connections. Therefore, the convergence of multimedia communication and wireless mobile networking technologies into the next generation wireless multimedia (WMM) networks with the vision of "anytime, anywhere, anyform" information system is the certain trend in the foreseeable future. However, successful combination of these two technologies presents many challenges such as available spectral bandwidth, energy efficiency, seamless end-to-end communication, robustness, security, etc."

Many countries around the world are investing a great amount of resources in government IT initiatives. However, few of these projects achieve their stated goals and some of them are complete failures. Therefore, understanding e-government success has become very important and urgent in recent years. In order to develop relevant knowledge about this complex phenomenon, researchers and practitioners need to identify and assess what are the main conditions, variables, or factors that have an impact on e-government success. However, before being able to evaluate these impacts, it is necessary to define what e-government success is and what some e-government success measures are. This book presents a review of both e-government success measures and e-government success factors. It also provides empirical evidence from quantitative analysis and two in-depth case studies. Although based on sound theory and rigorous empirical analysis, the book not only significantly contributes to academic knowledge, but also includes some practical recommendations for government officials and public managers. Theoretically, the book proposes a way to quantitatively operationalize Fountain's enactment framework. Based on the institutional tradition, the technology enactment framework attempts to explain the effects of organizational forms and institutional arrangements on the information technology used by government agencies. According to Fountain (1995; 2001) the technology enactment framework pays attention to the relationships among information technology, organizations, embeddedness, and institutions. This framework is very well known in the e-government field, but is normally used for qualitative analysis and there is no previous proposal of how to use it with quantitative data. The book proposes variables to measure each of the different constructs in this framework and also tests the relationships hypothesized by Fountain's theory. Finally, using the advantages of the selected quantitative analysis technique (Partial Least Squares), the study also proposes some adjustments and extensions to the original framework in a theory building effort. Methodologically, the book reports on one of the first multi-method studies in the field of e-government in general and e-government success in particular. This study uses a nested research design, which combines statistical analysis with two in depth case studies. The study begins with a statistical analysis using organizational, institutional, and contextual factors as the independent variables. An overall score representing e-government success in terms of the functionality of state websites is the dependent variable. Second, based on the statistical results two cases are selected based on their relative fitness to the model (residuals) and their position in the general ranking of website functionality (which includes four different measures). In order to complement the results of the statistical analysis, case studies were developed for the two selected states (New York and Indiana), using semi-structured interviews and document analysis. In terms of the statistical analysis, the book constitutes one of the first applications of Partial Least Squares (PLS) to an e-government success study. PLS is a structural equations modeling (SEM) technique and, therefore, allows estimating the measurement model and the structural model simultaneously. The use of this sophisticated statistical strategy helped to test the relationships between e-government success and different factors influencing it, as well as some of the relationships between several of the factors, thus allowing exploring some indirect effects too. |
