The volume develops the foundations of differential geometry so as to include finite-dimensional spaces with singularities and nilpotent functions, at the same level as is standard in the elementary theory of schemes and analytic spaces. The theory of differentiable spaces is developed to the point of providing a handy tool including arbitrary base changes (hence fibred products, intersections and fibres of morphisms), infinitesimal neighbourhoods, sheaves of relative differentials, quotients by actions of compact Lie groups and a theory of sheaves of Frchet modules paralleling the useful theory of quasi-coherent sheaves on schemes. These notes fit naturally in the theory of C^\infinity-rings and C^\infinity-schemes, as well as in the framework of Sp...

This book discusses the design, performance and implementation of access protocols with emphasis on how such protocols can efficiently support disparate classes of multimedia traffic. These protocols are deployed or experimented in various broadband wireless environments such as wireless ATM, satellite networks, mobile cellular and personal communication systems, wireless local loops, wireless local area networks, and others. Besides a comprehensive introduction and survey to the evolution of access protocols, some of the hottest topics of current interest are covered. These include: Connection control and QoS provisioning. Traffic load balancing techniques. Developments in advanced CDMA/TDMA/OFDM systems. International standardization effort...

This book collects the extended versions of the best papers presented at the 3rd International Conference on Autonomous Robots and Agents, ICARA 2006, held at Palmerston North, New Zealand, December, 2006. It covers theoretical and methodological aspects of incorporating intelligence in autonomous robots and agents, detailing the collaborative efforts and methods needed to overcome challenges faced in the real world and accomplish complex tasks....

This book represents the work of top scientists in the field of intelligent control and its applications, prognostics, diagnostics, condition based maintenance and unmanned systems. The work presents an approach to solving engineering problems related to manufacturing, automation, and especially unmanned systems and describes recent advances in the disciplines mentioned above. The main goal of the book is to demonstrate how concepts and ideas from diverse disciplines are merged within a common framework applied to the solution of complex problems....

The proliferation of wireless networks and small portable computing devices has led to the emergence of the mobile computing paradigm. Mobile and nomadic users carrying laptops or hand-held computers are able to connect to the Internet through publicly available wireline or wireless networks. In the near future, this trend can only grow as exciting new services and infrastructures delivering wireless voice and multimedia data are deployed. Any Time, Anywhere Computing: Mobile Computing Concepts and Technology is intended for technical and non-technical readers. It includes substantial coverage of the technologies that are shaping mobile computing. Current and future portables technology is covered and explained. Similarly, current and future wireles...
