Voice over Internet Protocol (VoIP) has recently evolved from a simple capability for transporting voice communications into a much more powerful technology capable of changing the way voice applications are constructed, delivered, marketed and sold. Whilst VoIP has clearly provided a focus for much debate within the telecommunications industry, there has been a clear gulf between hype and reality. However the questions now being asked have migrated from 'Will it work?' to 'What will the industry look like when it is delivered at scale?' In Voice over IP: systems and solutions, Richard Swale has brought together key contributors from within the BT Group and externally, to cover all of the important issues surrounding telephony over IP networks. This authoritative book examines VoIP as a technology and its consideration within the industry, the motivations for VoIP networks, a review of the status of the major components of a VoIP network and their development, and both current and emerging applications. VoIP technology blurs the boundaries between fixed, mobile and multimedia communications and the implications are explored and discussed. The primary market for this comprehensive book is telecommunications engineers and developers, service providers and regulators. However, all those with a technical or business interest in this rapidly developing area of communications technology will also find this book highly relevant.

As this comprehensive and multi-disciplinary anthology makes clear, virtuality has a pedigree that pre-dates the computer age and modern virtual worlds, a pedigree that can be traced back to classical mythology and beyond. Equally, the concept of virtuality is not the province of one field of study alone but is the foundation and driving force of many, both theoretical and applied. Our conceptualizations and applications of virtuality are multiple, as is shown across the nine sections of the book that move from philosophy to technologies and applications before returning to philosophy again for a discussion of the utopias and dystopias of virtuality. The almost 50 essays contained within range freely across subjects that include the potential of virtuality, ethics, virtuality and self, presence and immersion, virtual emotions, image, sound and literature, computer games, AI and A-Life, Augmented Reality and Real Virtuality, law and economics, medical and military applications, religion, and cybersex. Throughout, contributors discuss differences between virtuality, reality, and actuality, in debates filtered through the lenses of the disciplines represented here, and speculate on future directions. It is not at all clear that there are differences and, if such distinctions are to be found, the boundaries between virtuality, reality, and actuality continually shift as ideas, modes of organization, and behaviors constantly flow from one to the other regardless of direction. The Handbook presents no unified definition of virtuality to comfort the reader, rather a multiplicity of questions and approaches underpinned by provocative statements that should further fuel the debates surrounding our notions of virtuality.

In order to build a successful, Java-based application it is important to have a clear understanding of the principles underlying the various financial models. Those models guide the application designer in choosing the most appropriate Java data structures and implementation strategy. This book describes the principles of model building in financial engineering and explains those models as designs and working implementations for Java-based applications.

Throughout the book a series of packaged classes are developed to address a wide range of financial applications. Java methods are designed and implemented based on the most widely used models in financial engineering and investment practice. The classes and methods are explained and designed in a way which allows the financial engineer complete flexibility. The classes can be used as off-the-shelf working solutions or the innovative developer can re-arrange and modify methods to create new products

Virtual texts have emerged within the realm of the Internet as the predominant means of global communication. As both technological and cultural artifacts, they embody and challenge cultural assumptions and invite new ways of conceptualizing knowledge, community, identity, and meaning. But despite the pervasiveness of the Internet in nearly all aspects of contemporary life, no single resource has cataloged the ways in which numerous disciplines have investigated and critiqued virtual texts. This bibliography includes more than 1500 annotated entries for books, articles, dissertations, and electronic resources on virtual texts published between 1988 and 1999.

Because of the multiple contexts in which virtual texts are studied, the bibliography addresses virtual communication across a broad range of disciplines and philosophies. It encompasses studies of the historical development of virtual texts; investigations of the many interdisciplinary applications of virtual texts and discussions of such legal issues as privacy and intellectual property. Entries are arranged alphabetically within topical chapters, and extensive indexes facilitate easy access.

Web-based Support Systems (WSS) are an emerging multidisciplinary research area in which one studies the support of human activities with the Web as the common platform, mediumandinterface.TheInternetaffectseveryaspectofourmodernlife. Moving support systems to online is an increasing trend in many research domains. One of the goals of WSS research is to extend the human physical limitation of information processing in the information age. Research on WSS is motivated by the challenges and opportunities arising from the Internet. The availability, accessibility and ?exibility of information as well as the tools to access this information lead to a vast amount of opportunities. H- ever, there are also many challenges we face. For instance, we have to deal with more complex tasks, as there are increasing demands for quality and productivity. WSS research is a natural evolution of the studies on various computerized support systems such as Decision Support Systems (DSS), Computer Aided Design (CAD), and Computer Aided Software Engineering (CASE). The recent advancement of computer and Web technologies make the implementation of more feasible WSS. Nowadays, it is rare to see a system without some type of Web interaction. The research of WSS is classi?ed into four groups. WSS for speci?c domains."

Middleware Networks: Concept, Design and Deployment of Internet Infrastructure describes a framework for developing IP Service Platforms and emerging managed IP networks with a reference architecture from the AT&T Labs GeoPlex project. The main goal is to present basic principles that both the telecommunications industry and the Internet community can see as providing benefits for service-related network issues. As this is an emerging technology, the solutions presented are timely and significant. Middleware Networks: Concept, Design and Deployment of Internet Infrastructure illustrates the principles of middleware networks, including Application Program Interfaces (APIs), reference architecture, and a model implementation. Part I begins with fundamentals of transport, and quickly transitions to modern transport and technology. Part II elucidates essential requirements and unifying design principles for the Internet. These fundamental principles establish the basis for consistent behavior in view of the explosive growth underway in large-scale heterogeneous networks. Part III demonstrates and explains the resulting architecture and implementation. Particular emphasis is placed upon the control of resources and behavior. Reference is made to open APIs and sample deployments. Middleware Networks: Concept, Design and Deployment of Internet Infrastructure is intended for a technical audience consisting of students, researchers, network professionals, software developers, system architects and technically-oriented managers involved in the definition and deployment of modern Internet platforms or services. Although the book assumes a basic technical competency, as it does not provide remedial essentials, any practitioner will find this useful, particularly those requiring an overview of the newest software architectures in the field.

An oft-repeated adage among telecommunication providers goes, "There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can't do all ve, at least do the rst three. " Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, and personalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

Databases have been designed to store large volumes of data and to provide efficient query interfaces. Semantic Web formats are geared towards capturing domain knowledge, interlinking annotations, and offering a high-level, machine-processable view of information. However, the gigantic amount of such useful information makes efficient management of it increasingly difficult, undermining the possibility of transforming it into useful knowledge.

The research presented by De Virgilio, Giunchiglia and Tanca tries to bridge the two worlds in order to leverage the efficiency and scalability of database-oriented technologies to support an ontological high-level view of data and metadata. The contributions present and analyze techniques for semantic information management, by taking advantage of the synergies between the logical basis of the Semantic Web and the logical foundations of data management. The book's leitmotif is to propose models and methods especially tailored to represent and manage data that is appropriately structured for easier machine processing on the Web.

After two introductory chapters on data management and the Semantic Web in general, the remaining contributions are grouped into five parts on Semantic Web Data Storage, Reasoning in the Semantic Web, Semantic Web Data Querying, Semantic Web Applications, and Engineering Semantic Web Systems. The handbook-like presentation makes this volume an important reference on current work and a source of inspiration for future development, targeting academic and industrial researchers as well as graduate students in Semantic Web technologies or database design.

With the advent of new technologies and governmental regulation, notably the Telecommunications Act of 1996, not only has the broadcast industry changed dramatically, but also the laws covering the management and its human resources. Executives must know and understand these changes to operate within the law and to make best use of their people. With careful attention to scholarly accuracy and the latest thinking, Scott's book approaches the crucial human resource problems in broadcasting with a hands-on awareness of what really goes on among broadcasting industry people and the organizations that depend on them. Scott writes for practitioners and provides the information they can use daily, supplying academic professionals and students of broadcasting management with an important resource.

Chapter 1 briefly describes the broadcast industry, with special attention to significant technological changes and regulations. Chapter 2 examines the standard regulatory challenges faced by broadcasters. Chapters 3 and 4 review the major management and motivational theories over the past 150 years. These theories are then critiqued and applied to current personnel problems. The section on broadcast ethics discusses moral and ethical frameworks to help managers make the right decisions. In Chapter 5, the duties of the human resource director are noted along with pertinent EEOC laws banning discrimination. Chapter 6 reviews the employment process, including interviewing, training, performance reviews, progressive discipline, and the proper, legal method to terminate an employee. Chapter 7 enumerates the duties and responsibilities of the programming area including the operations manager, chief engineer, program director, and other department heads. Types of radio and television programming are discussed along with effective scheduling strategies. The book concludes with Chapter 8, Sales, which includes discussions of the Arbitron and Nielsen ratings organizations, sales proposals, and duties of the sales personnel.

The SGML FAQ Book: Understanding the Foundation of HTML and XML is similar, but not quite the same kind of thing as an online FAQ or Frequently Asked Questions' list. It addresses questions from people who already actually use SGML in some way (including HTML authors), and people who are about to use it. It deals mainly with issues that arise when using SGML in practice. A very brief introduction to SGML is included as Appendix A. The questions discussed in The SGML FAQ Book are repeatedly heard by people who make their living serving the SGML community. SGML experts spend many hours teaching these details, sometimes repeatedly because some questions do not seem important - until you run into them. So one benefit of this book is learning more of the art of document creation and management, both by general reading before questions arise and by specific reference when a question arises. For the latter use, the appendices, glossary, and index are particularly important. A second benefit of this book is that it provides a common theme to its answers that you can apply in your use of SGML, HTML and related languages in general. The fundamental answer to many of the questions boils down to simplify': many questions do not show up if you use the simple, elegant core of SGML without worrying about optional features. The credo of this book is simply, SGML doesn't need to be complicated'. SGML has the potential for complexity at certain points. But much of the complexity comes from optional parts and can be avoided. SGML methodology and its primary benefits suffer no loss even if you skip many features, which speaks well for the quality of SGML's overall design. Many of the questions discussedinvolve those optional parts, and therefore can be avoided by judicious designers and authors. The two key goals of the book are (1) to answer questions that you may actually encounter as an SGML user, and to help you get unstuck' and be as productive as possible in using the language and (2) to show proactive ways you can simplify your use of SGML, and get its very substantial benefits with minimal complexity.

With the increasing proliferation of information-technology and, especially, Web-based approaches to the implementation of systems and services, researchers, educators, and practitioners worldwide are experiencing a rising need for authoritative references to enhance their understanding of the most current and effective engineering practices leading to robust and successful solutions.""Integrated Approaches in Information Technology and Web Engineering: Advancing Organizational Knowledge Sharing"" presents comprehensive, research-driven insights into the field of Web engineering. This book collects over 30 authoritative articles from distinguished international researchers in information technology and Web engineering, creating an invaluable resource for library reference collections that will equip researchers and practitioners in academia and industry alike with the knowledge base to drive the next generation of innovations.

This book investigates the characteristics of simple versus complex systems, and what the properties of a cyber-physical system design are that contribute to an effective implementation and make the system understandable, simple to use, and easy to maintain. The targeted audience is engineers, managers and advanced students who are involved in the design of cyber-physical systems and are willing to spend some time outside the silo of their daily work in order to widen their background and appreciation for the pervasive problems of system complexity. In the past, design of a process-control system (now called cyber-physical systems) was more of an art than an engineering endeavor. The software technology of that time was concerned primarily with functional correctness and did not pay much attention to the temporal dimension of program execution, which is as important as functional correctness when a physical process must be controlled. In the ensuing years, many problems in the design of cyber-physical systems were simplified. But with an increase in the functional requirements and system size, the complexity problems have appeared again in a different disguise. A sound understanding of the complexity problem requires some insight in cognition, human problem solving, psychology, and parts of philosophy. This book presents the essence of the author's thinking about complexity, accumulated over the past forty years.

The cryptosystems based on the Integer Factorization Problem (IFP), the Discrete Logarithm Problem (DLP) and the Elliptic Curve Discrete Logarithm Problem (ECDLP) are essentially the only three types of practical public-key cryptosystems in use. The security of these cryptosystems relies heavily on these three infeasible problems, as no polynomial-time algorithms exist for them so far. However, polynomial-time quantum algorithms for IFP, DLP and ECDLP do exist, provided that a practical quantum computer exists.

"Quantum Attacks on Public-Key Cryptosystems" presemts almost allknown quantum computing based attacks on public-key cryptosystems, with an emphasis on quantum algorithms for IFP, DLP, and ECDLP. It also discusses some quantum resistant cryptosystems to replace the IFP, DLP and ECDLP based cryptosystems.

This book is intended to be used either as a graduate text in computing, communications and mathematics, or as a basic reference in the field.

This book presents cutting-edge work on real-time modelling and processing, a highly active research field in both the research and industrial domains. Going beyond conventional real-time systems, major efforts are required to develop accurate and computational efficient real-time modelling algorithms and design automation tools that reflect the technological advances in high-speed and ultra-low-power transceiver communication architectures based on nanoscale devices. The book addresses basic and more advanced topics, such as I/O buffer circuits for ensuring reliable chip-to-chip communication, I/O buffer behavioural modelling, multiport empirical models for memory interfaces, compact behavioural modelling for memristive devices, and resource reservation modelling for distributed embedded systems. The respective chapters detail new research findings, new models, algorithms, implementations and simulations of the above-mentioned topics. As such, the book will help both graduate students and researchers understand the latest research into real-time modelling and processing.

Towards a Digital Renaissance traces the excitement and optimism of the early internet, the outsider cyberpunk ethic and open access. But it also monitors the more complex but ultimately more commercialised online world of today, a world dominated by corporate business in which many feel that surveillance has become overwhelming. Jeremy Silver's involvement in various start-ups, both as CEO and investor, led to his leadership of Digital Catapult. Towards a Digital Renaissance examines the interplay between state and private financing in the digital sector. It also argues for the internet's potential to transition from a 'medieval' world of the GAFA big four (Google, Amazon, Facebook and Apple), closed and walled up like medieval city states, to a 'digital renaissance' based on the free exchange of ideas and an enabling metaverse made up of virtual reality and artificial intelligence that deepens our experience of reality rather than restricting or monitoring it.

Web search engines are not just indispensable tools for finding and accessing information online, but have become a defining component of the human condition and can be conceptualized as a complex behavior embedded within an individual's everyday social, cultural, political, and information-seeking activities. This book investigates Web search from the non-technical perspective, bringing together chapters that represent a range of multidisciplinary theories, models, and ideas.
