There has been tremendous emphasis in unmanned aerial vehicles, both of fixed (airplanes) and rotary wing (vertical take off and landing, helicopters) types over the past ten years. Applications span both civilian and military domains, the latter being the most important at this stage. This edited book provides a solid and diversified reference source related to basic, applied research and development on small and miniature unmanned aerial vehicles, both fixed and rotary wing. As such, the book offers background information on the evolution of such vehicles over the years, followed by modeling and control fundamentals that are of paramount importance due to unmanned aerial vehicle model complexity, nonlinearity, coupling, inhirent instability and parameter values uncertainty. Aspects of navigation, including visual-based navigation and target tracking are discussed, followed by applications to attitude estimation on micro unmanned aerial vehicles, autonomous solar unmanned aerial vehicle, biomimetic sensing for autonomous flights in near-earth environments, localization of air-ground wireless sensor networks, decentralized formation tracking, design of an unmanned aerial vehicle for volcanic gas sampling and design of an on-board processing controller for miniature helicopters. more...

This book constitutes the thoroughly refereed post-proceedings of the 8th International Workshop on Mining Web Data, WEBKDD 2006, held in Philadelphia, PA, USA in August 2006 in conjunction with the 12th ACM SIGKDD International Conference on Knowledge Discovery and Data Mining, KDD 2006. The 13 revised full papers presented together with a detailed preface went through two rounds of reviewing and improvement and were carefully selected for inclusion in the book. The enhanced papers show new technologies from areas like adaptive mining methods, stream mining algorithms, techniques for the Grid, especially flat texts, documents, pictures and streams, usability, e-commerce applications, personalization, and recommendation engines. more...

Agenda Relevance is the first volume in the authors' omnibus investigation of. the logic of practical reasoning, under the collective title, A Practical Logic. of Cognitive Systems. In this highly original approach, practical reasoning is. identified as reasoning performed with comparatively few cognitive assets,. including resources such as information, time and computational capacity. Unlike. what is proposed in optimization models of human cognition, a practical reasoner. lacks perfect information, boundless time and unconstrained access to. computational complexity. The practical reasoner is therefore obliged to be a. cognitive economizer and to achieve his cognitive ends with considerable. efficiency. Accordingly, the practical reasoner avails himself of various. scarce-resource compensation strategies. He also possesses neurocognitive. traits that abet him in his reasoning tasks. Prominent among these is the. practical agent's striking (though not perfect) adeptness at evading irrelevant. information and staying on task. On the approach taken here, irrelevancies are. impediments to the attainment of cognitive ends. Thus, in its most basic sense,. relevant information is cognitively helpful information. Information can then be. said to be relevant for a practical reasoner to the extent that it advances or. closes some cognitive agenda of his. The book explores this idea with a. conceptual detail and nuance not seen the standard semantic, probabilistic and. pragmatic approaches to relevance; but wherever possible, the authors seek to. integrate alternative conceptions rather than reject them outright. A further. attraction of the agenda-relevance approach is the extent to which its principal. conceptual findings lend themselves to technically sophisticated re-expression. in formal models that marshal the resources of time and action logics and. label led deductive systems. Agenda Relevance is necessary reading for researchers in logic, belief. dynamics, more...

Multi-agent systems are one of the most exciting research areas in Artificial Intelligence. In the last ten years there has been a growing interest in the application of agent-based systems in health care. Moreover, a growing European community of researchers interested in the application of intelligent agents in health care emerged as a result of the activities within the AgentCities.NET European network and the AgentLink III Technical Forum Group on Healthcare Applications of Intelligent Agents. And specially in R&D projects funded during the FP6. Thus, this book reports on the results achieved in this area, discuss the benefits (and drawbacks) that agent-based systems may bring to medical domains and society, and also to provide a list of the research topics that should be tackled in the near future to make the deployment of health-care agent-based systems a reality. Current topics of research include communication and co-operation betweendistributed intelligent agents to manage patient care, information agents that retrieve medical information from the Internet, and multi-agent systems that assist the doctors in the tasks of monitoring and diagnosis. A lot of methodological and technical problems are beginning to be discovered by the researchers that attempt to deploy agent-based systems in the medical area; just to name a few, there does not exist a universally accepted standard medical ontology, it is difficult to integrate new agent systems with legacy software, and these new agent-based systems should take into account rapidly changing national and international laws and regulations concerning the privacy of medical data and the security of the transaction of patientinformation between agents. The reader will find a comprehensive view of the field and up-to-date state-of-the-art of the research in this field in Europe. more...

This book reconciles the existence of technical trading with the Efficient Market Hypothesis. By analyzing a well-known agent-based model, the Santa Fe Institute Artificial Stock Market (SFI-ASM), it finds that when selective forces are weak, financial evolution cannot guarantee that only the fittest trading rules will survive.Its main contribution lies in the application of standard results from population genetics which have widely been neglected in the agent-based community. This has led to various misinterpretations of previous simulation results. The book is able to finally establish the emergence of technical trading for faster learning speeds in the SFI-ASM beyond a doubt. In emphasizing the importance of genetic drift as an important evolutionary factor and analyzing its effects on various mutation operators, this book provides agent-based modelers with several tools to design better evolutionary algorithms. more...
