Proceedings of the Third International Mobile Satellite Conference (IMSC 1993)

Satellite-based mobile communications systems provide voice and data communications to users over a vast geographic area. The users may communicate via mobile or hand-held terminals, which may also provide access to terrestrial cellular communications services. While the first and second International Mobile Satellite Conferences (IMSC) mostly concentrated on technical advances, this Third IMSC also focuses on the increasing worldwide commercial activities in Mobile Satellite Services. Because of the large service areas provided by such systems, it is important to consider political and regulatory issues in addition to technical and user requirements issues. Topics covered include: the direct broadcast of audio programming from satellites; spacecraft technology; regulatory and policy considerations; advanced system concepts and analysis; propagation; and user requirements and applications

Mobile Ad-Hoc Networks

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications. It is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks

Proceedings of the Fifth International Mobile Satellite Conference 1997

Satellite-based mobile communications systems provide voice and data communications to users over a vast geographic area. The users may communicate via mobile or hand-held terminals, which may also provide access to terrestrial communications services. While previous International Mobile Satellite Conferences have concentrated on technical advances and the increasing worldwide commercial activities, this conference focuses on the next generation of mobile satellite services. The approximately 80 papers included here cover sessions in the following areas: networking and protocols; code division multiple access technologies; demand, economics and technology issues; current and planned systems; propagation; terminal technology; modulation and coding advances; spacecraft technology; advanced systems; and applications and experiments

Endangered Languages and Languages in Danger

This peer-reviewed collection brings together the latest research on language endangerment and language rights. It creates a vibrant, interdisciplinary platform for the discussion of the most pertinent and urgent topics central to vitality and equality of languages in today’s globalised world. The novelty of the volume lies in the multifaceted view on the variety of dangers that languages face today, such as extinction through dwindling speaker populations and lack of adequate preservation policies or inequality in different social contexts (e.g. access to justice, education and research resources). There are examples of both loss and survival, and discussion of multiple factors that condition these two different outcomes. We pose and answer difficult questions such as whether forced interventions in preventing loss are always warranted or indeed viable. The emerging shared perspective is that of hope to inspire action towards improving the position of different languages and their speakers through research of this kind

American Cities in Post- Apocalyptic Science Fiction

Visions of the American city in post-apocalyptic ruin permeate literary and popular fiction, across print, visual, audio and digital media. American Cities in Post-Apocalyptic Science Fiction explores the prevalence of these representations in American culture, drawing from a wide range of primary and critical works from the early-twentieth century to today. Beginning with science fiction in literary magazines, before taking in radio dramas, film, video games and expansive transmedia franchises, Robert Yeates argues that post-apocalyptic representations of the American city are uniquely suited for explorations of contemporary urban issues. Examining how the post-apocalyptic American city has been repeatedly adapted and repurposed to new and developing media over the last century, this book reveals that the content and form of such texts work together to create vivid and immersive fictional spaces in ways that would otherwise not be possible. Chapters present media-specific analyses of these texts, situating them within their historical contexts and the broader history of representations of urban ruins in American fiction. Original in its scope and cross-media approach, American Cities in Post-Apocalyptic Science Fiction both illuminates little-studied texts and provides provocative new readings of familiar works such as Blade Runner and The Walking Dead, placing them within the larger historical context of imaginings of the American city in ruins
