The millimeter-wave frequency band (30–300 GHz) is considered a potential candidate to host very high data rate communications. First used for high capacity radio links and then for broadband indoor wireless networks, the interest in this frequency band has increased as it is proposed to accommodate future 5G mobile communication systems. The large bandwidth available will enable a number of new uses for 5G. In addition, due to the large propagation attenuation, this frequency band may provide some additional advantages regarding frequency reuse and communication security. However, a number of issues have to be addressed to make mm-wave communications viable. This book collects a number of contributions that present solutions to these challenges.
This book provides basic tools for learning how to model in mathematical programming, from models without much complexity to complex system models. It presents a unique methodology for the building of an integral mathematical model, as well as new techniques that help build under own criteria. It allows readers to structure models from the elements and variables to the constraints, a basic modelling guide for any system with a new scheme of variables, a classification of constraints and also a set of rules to model specifications stated as logical propositions, helping to better understand models already existing in the literature. It also presents the modelling of all possible objectives th...
Artificial intelligence is no longer solely the preserve of computer scientists and researchers; it is now a part of all our lives, and hardly a day goes by without discussion and debate about the implications of its many applications in the mainstream media. This book presents the proceedings of CCIA 2023, the 25th International Conference of the Catalan Association for Artificial Intelligence, held from 25 - 27 October 2023 in Barcelona, Spain. CCIA serves as an annual forum welcoming participants from around the globe. The theme of the 2023 conference was Supportive AI, the main goals of which are to strengthen collaboration between research and industry by sharing the latest advances in ...
Focusing on stunning paintings and engravings from around the world, 16 papers interrogate the driving forces behind global rock art research. Many of the motifs featured were created by indigenous hunter-gatherer groups; this book sheds new light on non-Western rituals and worldviews, many of which are threatened or on the point of extinction.
Modeling and Simulation Environment for Satellite and Terrestrial Communications Networks: Proceedings of the European COST Telecommunications Symposium will be of interest to network designers, developers, and operators. This book is a collection of papers given at the European Cost Telecommunications Symposium. The Symposium was broken down into four sessions: Modelling and Simulation. Teletraffic Modelling. Communications Networks Simulation. Problems in Simulation. Each session addressed a wide spectrum of subjects. The symposium covered nearly all of the important aspects of simulation modeling and tools for the design and performance evaluation of communication techniques and systems. Emerging techniques were emphasized. Modeling and Simulation Environment for Satellite and Terrestrial Communications Networks: Proceedings of the European COST Telecommunications Symposium is a useful reference work for practicing engineers and academic researchers.
"This book highlights new research regarding wireless identification and sensing platform (WISP) tags, security, and applications, serving as a reference on WISP technology and presenting recent advances in this field"--Provided by publisher.
Based on a major research programme, and originally published in 1985, this book looked to provide an economic foundation for reinterpreting the Neolithic-Bronze Age sequence of South-east Spain in terms of emergent social complexity. The cultural evolution of the area had already been considered in terms of influence from the eastern Mediterranean but this book uses site catchment analysis to give an economic baseline for all thirty-five of the better-known prehistoric settlements of the region. Site catchment analysis assumes that people minimised transport costs in production and that ancient and modern resource spaces correspond systematically. This research therefore studied modern land...
This book constitutes the refereed proceedings of the 8th International Joint Conference on E-Business and Telecommunications, ICETE 2011, held in Seville, Spain in July 2011. The 118 revised full papers presented were carefully reviewed and selected from 409 submissions. The topics covered are data communication networking, e-business, optical communication systems, security and cryptography, signal processing and multimedia applications, and wireless networks and information systems. These are the main knowledge areas that define the six component conferences, namely: DCNET, ICE-B, OPTICS, SECRYPT, SIGMAP, and WINSYS which together form the ICETE joint conference.
th This book contains the best papers of the 5 International Conference on e-Business and Telecommunications (ICETE), which was held in July 2008, in Porto, Portugal. This conference reflects a continuing effort to increase the dissemination of recent research results among professionals who work in the areas of e-business and te- communications. ICETE is a joint international conference integrating four major areas of knowledge that are divided into four corresponding conferences: ICE-B (- ternational Conf. on e-Business), SECRYPT (International Conf. on Security and Cryptography), SIGMAP (Int’l Conf. on Signal Processing and Multimedia) and WINSYS (International Conf. on Wireless Informa...
