ISDN presents a new challenge for educators and trainers. This book provides an introduction to the technology for educators interested firstly in whether to use it and secondly in how to use it. The first three chapters discuss practical, educational and strategic issues related to these two questions. The following ten chapters provide case studies of education and training uses of ISDN technologies in Europe, the US and Australia. These involve videoconferencing, audiographics, desktop conferencing and image banks. The book concludes with a large glossary of explanatory material.

Humanitarian services seek to promote welfare to save lives, maintain human dignity, alleviate suffering, strengthen preparedness, and provide material and logistical assistance in response to humanitarian crises. They are thus different from development aids that address underlying socioeconomic factors and provides support for the social, economic and political developments of developing nations. Information and Communication Technologies (ICTs) are becoming the backbone technologies for providing quality and efficient services and are playing an increasingly important and sophisticated role in humanitarian-service activities. Many ICT-based solutions exist such as tools to support the work of humanitarian organizations, mobile applications and solutions to provide health services, open source web portals for disaster management systems, and mobile and autonomous devices to provide assistance.

Set against critiques of neoliberal capitalism in the present, Infrastructural Attachments argues that the technopolitics of austerity have been the organizing logic of statecraft in Kenya since the late nineteenth century, calling into question the novelty of austerity as a mode of governance and a lived experience. Using infrastructures as a lens to explore state formation over the long twentieth century—roads in the early colonial period, radio broadcasting from the interwar through the postwar periods, and mobile phones and digital financial services in the present—historian Emma Park reveals that as the state drew on private capital to make up for limited budgets, it inaugurated a peculiar political-economic form: the corporate-state. For more than a century—in pursuit of minimizing costs and maximizing profits—the corporate-state crucially relied on the exploitation and expropriation of its subject-citizens. By foregrounding these workers, Park interrogates how Kenyans’ knowledge and expertise has been rescaled and subsumed, quietly underwriting the development of infrastructural expertise, the circuits of finance upon which (post)colonial infrastructural expansion has been premised, and the forms of profit-making it has enabled.

This book describes the stage-by-stage creation and development, from the mid-nineteenth century to the present day, of the remarkable global communications technologies that have profoundly transformed the way that people live and work.

This book explains how intelligence can be introduced into digital telephone networks. Beginning by outlining the basic principles of Intelligent Networks (IN), it tracks the application of the IN principle of separation of the service logic for advanced telephony services from the underlying call control infrastructures. The book explains how large public networks are updated to incorporate IN principles for advanced telephony services. This is illustrated using many practical examples which are set against a background of following the ETSI standards within the overall ITU-T framework of recommendations. This book is targeted at postgraduate telecommunications students, or engineers requiring a concise and practical introduction to IN.

Broadband networks, such as asynchronous transfer mode (ATM), frame relay, and leased lines, allow us to easily access multimedia services (data, voice, and video) in one package. Exploring why broadband networks are important in modern-day telecommunications, Introduction to Broadband Communication Systems covers the concepts and components of both standard and emerging broadband communication network systems.

Smart City and sensing platforms are considered some of the most significant topics in the Internet of Things (IoT). Sensors are at the heart of the IoT, and their development is a key issue if such concepts are to achieve their full potential.

Ionospheric Radio replaces an earlier publication Ionospheric Propogation and is aimed at professional scientists, engineers, and students who need an intermediate-level reference and/or text. Students of aeronomy and radio wave propogation are introduced to basic wave theory in absorbing, anisotropic and dispersive media, and to the physics of production, loss and movement of plasma in the ionosphere in the presence of the geomagnetic field. Various radio techniques are described, and applications to the interpretation of ionospheric structures and dynamics are presented. The application of ionospheric data to radio communications problems includes the use of numerical and physical models and prediction techniques, and methods for calculating signal strengths are presented. Topics include Earth-space propagation, ionospheric modification, ionospheric disturbances, propagation by scattering from plasma irregularities, topside sounding, and propagation on frequencies from the extremely low to the super high. Reference lists are extensive and a section of questions tests the reader's understanding of the material.

Iris recognition technologies for identity management are already deployed globally in several large-scale nationwide biometric projects and are currently entering the mobile market. More recently, periocular recognition has been employed to augment the biometric performance of the iris in unconstrained environments where only the ocular region is present in the image.
