Wireless Sensor Networks: Deployments and Design Frameworks

by Elena Gaura Michael Allen James Brusey Geoffrey Challen Lewis Girod

The twentieth century ended with the vision of smart dust: a network of wirelessly connected devices whose size would match that of a dust particle, each one a se- containedpackageequippedwithsensing,computation,communication,andpower. Smart dust held the promise to bridge the physical and digital worlds in the most unobtrusive manner, blending together realms that were previously considered well separated. Applications involved scattering hundreds, or even thousands, of smart dust devices to monitor various environmental quantities in scenarios ranging from habitat monitoring to disaster management. The devices were envisioned to se- organize to accomplish their task in the most ef?cient way. As such, smart dust would become a powerful tool, assisting the daily activities of scientists and en- neers in a wide range of disparate disciplines. Wireless sensor networks (WSNs), as we know them today, are the most no- worthy attempt at implementing the smart dust vision. In the last decade, this ?eld has seen a fast-growing investment from both academia and industry. Signi?cant ?nancial resources and manpower have gone into making the smart dust vision a reality through WSNs. Yet, we still cannot claim complete success. At present, only specialist computerscientists or computerengineershave the necessary background to walk the road from conception to a ?nal, deployed, and running WSN system.

Trade Wins or Trade Wars: The Perceptions and Knowledge in the Free Trade Debate

by Bogna Gawrońska-Nowak Piotr Lis Joanna Konieczna-Sałamatin

This book tackles the disconnect between social perceptions and expert knowledge regarding trade policy decisions. Using a Polish language internet database, the authors shed light on areas that need to be addressed when considering the adoption of particular trade policies by applying content and statistical analysis to produce an easy to deploy measure of populism in digital media, the “Media Populism Ratio”. Defining a mismatch between social perception and expert knowledge may contribute to a better understanding of the controversies on free trade, as well as properly defining possible sources of populism and social conflicts – therefore also revealing some potential weaknesses in the trade policy implementation level which are at times neglected or underestimated. The book will be relevant to students and researchers interested in economic policy, economic narratives and cultural economics.

Broadband Satellite Communication Systems and the Challenges of Mobility is an essential reference for both academic and professional researchers in the field of telecommunications, computer networking and wireless networks. Recently the request of multimedia services has been rapidly increasing and satellite networks appear to be attractive for a fast service deployment and for extending the typical service area of terrestrial systems. In comparison with traditional wide area networks, a characteristic of satellite communication systems is their ability in broadcasting and multicasting multimedia information flows anywhere over the satellite coverage. The papers presented in this volume highlight key areas such as Satellite Network Architectures, Services and Applications; Mobile Satellite Systems and Services; and Hybrid Satellite and Terrestrial Networks. Mobility will inevitably be one of the main characteristics of future networks, terminals and applications and, thus, extending and integrating fixed network protocols and services to mobile systems represents one of the main issues of present networking. The secondary focus of this volume is on challenges of mobility, that is, on technologies, protocols and services for the support of seamless and nomadic user access to new classes of applications in person-to-person, device-to-device and device-to-person environments. The book comprises recent results of research and development in the following areas; Seamless mobility; Mobile ad hoc and sensor networks; Analysis, simulation and measurements of mobile and wireless systems; Integration and inter-working of wired and wireless networks; QoS in mobile and wireless networks; Future trends and issues concerning mobility. This state -of-the-art volume contains a collection of papers from two of the workshops of the 18th IFIP World Computer Congress, held August 22-27, 2004, in Toulouse, France: the Workshop on Broadband Satellite Communication Systems, and the Workshop on the Challenges of Mobility.

Languages – Cultures – Worldviews: Focus on Translation (Palgrave Studies in Translating and Interpreting)

by Adam Głaz

This edited book explores languages and cultures (or linguacultures) from a translation perspective, resting on the assumption that they find expression as linguacultural worldviews. Specifically, it investigates how these worldviews emerge, how they are constructed, shaped and modified in and through translation, understood both as a process and a product. The book’s content progresses from general to specific: from the notions of worldview and translation, through a consideration of how worldviews are shaped in and through language, to a discussion of worldviews in translation, both in macro-scale and in specific details of language structure and use. The contributors to the volume are linguists, linguistic anthropologists, practising translators, and/or translation studies scholars, and the book will be of interest to scholars and students in any of these fields.

Polar Codes: A Non-Trivial Approach to Channel Coding (Springer Topics in Signal Processing #15)

by Orhan Gazi

This book explains the philosophy of the polar encoding and decoding technique. Polar codes are one of the most recently discovered capacity-achieving channel codes. What sets them apart from other channel codes is the fact that polar codes are designed mathematically and their performance is mathematically proven. The book develops related fundamental concepts from information theory, such as entropy, mutual information, and channel capacity. It then explains the successive cancellation decoding logic and provides the necessary formulas, moving on to demonstrate the successive cancellation decoding operation with a tree structure. It also demonstrates the calculation of split channel capacities when polar codes are employed for binary erasure channels, and explains the mathematical formulation of successive cancellation decoding for polar codes. In closing, the book presents and proves the channel polarization theorem, before mathematically analyzing the performance of polar codes.
