A Practical Logic of Cognitive Systems
The Reach of Abduction: Insight and Trial
1st Edition
Dov M. Gabbay + 1 more
English
The present work is a continuation of the authors' acclaimed multi-volume APractical Logic of Cognitive Systems. After having investigated the notion ofrelevance in their previous volume, Gabbay and Woods now turn to abduction. Inthis highly original approach, abduction is construed as ignorance-preserving... in which conjecture plays a pivotal role. Abduction is a response to acognitive target that cannot be hit on the basis of what the agent currently knows.The abducer selects a hypothesis which were it true would enable the reasoner to attain his target. He concludes from this fact that the hypothesis may be conjectured. In allowing conjecture to stand in for the knowledge he fails to have, the abducer reveals himself to be a satisficer, since an abductive solution is not a solution from knowledge. Key to the authors' analysis is the requirement that a conjectured proposition is not just what a reasoner might allow himself to assume, but a proposition he must defeasibly release as a premiss for further inferences in the domain of enquiry in which the original abduction problem has arisen.The coverage of the book is extensive, from the philosophy of science tocomputer science and AI, from diagnostics to the law, from historical explanation to linguistic interpretation. One of the volume's strongest contributions is its exploration of the abductive character of criminal trials, with special attention given to the standard of proof beyond a reasonable doubt.Underlying their analysis of abductive reasoning is the authors' conception ofpractical agency. In this approach, practical agency is dominantly a matter of thecomparative modesty of an agent's cognitive agendas, together with comparatively scant resources available for their advancement. Seen in these ways, abduction has a significantly practical character, precisely because it is a form of inference that satisfices rather than maximizes its response to the agent's cognitive target.The Reach of Abduction will be necessary reading for researchers, graduatestudents and senior undergraduates in logic, computer science, AI, belief dynamics, argumentation theory, cognitive psychology and neuroscience, linguistics, forensic science, legal reasoning and related areas.Key features:- Reach of Abduction is fully integrated with a background logic of cognitive systems.- The most extensive coverage compared to competitive works.- Demonstrates not only that abduction is a form of ignorance preservinginference but that it is a mode of inference that is wholly rational.- Demonstrates the satisficing rather than maximizing character ofabduction.- The development of formal models of abduction is considerably more extensive than one finds in existing literature. It is an especially impressive amalgam of sophisticatedconcept... analysis and extensive logical modelling.
Elsevier's Dictionary of Automation Technics

English
This dictionary contains 13,000 terms with more than 4,000 cross-references used in the following fields: automation, technology of management and regulation, computing machine and data processing, computer control, automation of industry, laser technology, theory of information and theory of signals, theory of algorithms and programming, philosophical bases of cybernetics, cybernetics and mathematical methods.Automation pertains to the theory, art, or technique of making a machine, a process or a device more fully automatic. Computers and information processing equipment play a large role in the automation of a process because of the inherent ability of a computer to develop decision that will, in effect, control or govern the process from the information received by the computer concerning the status of the process. Thus automation pertains to both the theory, and techniques of using automatic systems in industrial applications and the processes of investigation, design and conversion to automatic methods. Automatic control, automatic materials handling, automatic testing, automatic packaging, for continuous as well as batch processing, are all considered parts of the overall or completely automatic process.The Dictionary consists of two parts, Basic Table and Indexes. In the first part the English terms are listed alphabetically, numbered consecutively and followed by its German, French and Russian equivalents. English synonyms appear as cross-references to the main entries in their proper alphabetical order. The second part of the Dictionary, the Indexes, contains separate alphabetical indexes of the German, French and Russian terms. The reference number(s) with each term stands for the number of the English term(s) in the basic table.Elsevier's Dictionary of Automatic Technics will be a valuable tool for specialists, scientists, students and everyone who takes interest in the problems of investigation devoted to the design, development, and applications of methods and techniques for rendering a process of group of machines self-actuating, self-moving, or self-controlling.
Iceland - Modern Processes and Past Environments
1st Edition
Volume 5
C. Caseldine + 3 more
English
Iceland provides an unique stage on which to study the natural environment, both past and present, and it is understanding both aspects of reconstructing the past and observing and interpreting the present that form the focus of the contributions to this volume. The papers are all written by active researchers and incorporate both reviews and new data. Although concentrating largely on the recent Quaternary timescale a wide range of topics is explored including subglacial volcanism, onshore and offshore evidence for the Last Glacial Maximum and subsequent deglaciation, current glacial characteristics including jökulhlaups and glacial landsystems, soil development, Holocene ecosystem change, current oceanography, impacts of volcanic sulphur loading, chemical weathering and the CO2 budget and documentary evidence for historical climate. The key element of the volume is that for the first time it provides a wide overview of a range of topics for which Iceland provides an almost unparalleled laboratory emphasizing the importance of research on this small island for studies over a much broader global scale. These reviews point the way to future research directions and are supplemented by extensive illustrations and a comprehensive bibliography.
New Theories for Chemistry
1st Edition
Jan C.A. Boeyens
English
Many new developments, related to the interpretation and importance of symmetry relationships, quantum mechanics, general relativity, field theory and mathematics have occurred in the second half of the 20th century without having a visible impact on chemical thinking. By re-examining basic theories, The New Theories for Chemistry aims to introduce a new understanding of old concepts, such as electron spin, The Periodic Table and electronegativity. The book focuses on the new mathematical concepts that enable the exploration of interactions between particles, waves and fields within a chemical context, and is packed with examples to support its arguments. The author adopts a practical approach and topics are arranged sequentially, from the mathematical basis through to general concepts. An essential reference source, this book is suitable for physicists, theoretical and physical chemists, as well as students and researchers working in the field.
Long-Term Performance of Permeable Reactive Barriers
1st Edition
Volume 7
K.E. Roehl + 3 more
English
While extensive research has been performed on many technological aspects of permeable reactive barriers and a number of contaminants have so far been successfully treated by PRB systems, long-term performance has not been extensively considered and little is known about the processes influencing long-term behaviour. This gap in our knowledge is all the more disadvantageous as design life has a decisive influence on the economic viability of PRBs. The book describes methods for evaluation and enhancement of the long-term performance of PRB systems, especially of those targeting heavy metals, specifically uranium, and organic contaminants by sorption and/or precipitation mechanisms. Major topics in the book are: Selection and characterisation of suitable reactive materials Characterisation of the relevant contaminant attenuation processes Developing new contaminant-binding chemical compounds ("ligands") Accelerated testing methods to assess the long-term performance of the attenuation mechanisms in PRBs Evaluation of the influence of site characteristics on PRB performance Monitoring of existing and new field installations Coupling of electrokinetic techniques and PRB systems Large-scale laboratory and field tests and their results It addresses the long-term performance of PRBs, an important feature of this novel remediation technology, systematically. It deals extensively with heavy metal removal, with special emphasis on uranium. A number of case studies, experiences with large-scale modelling and test site experiments provide insight into the practical application of the results. This volume will contribute to the science underpinning groundwater remediation, and this will result in the improvement of quality of life and health and safety.

Sleep and Aging
1st Edition
Volume 17
English
Alterations in sleep are common manifestations of aging that can lead to significant health problems and contribute to behavioural problems associated with age-related neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. Recent advances have revealed key cellular and molecular mechanisms involved in sleep regulation, and this knowledge is helping to advance an understanding of both the normal functions of sleep and the mechanisms responsible for abnormalities in sleep in various neurological conditions and during normal aging. This volume of Advances in Cell Aging and Gerontology brings together chapters by leaders in the fields of sleep research and the neurobiology of aging. The book starts with chapters describing fundamental aspects of the neurocircuitry involved in sleep, patterns of brain activity during the different stages of sleep and disturbances of sleep during aging. The links between depression, anxiety and insomnia are reviewed in regards to the underlying neurochemical alterations that appear to involve abnormalities in neurotransmitter and neurotrophic factor signalling. The evolutionary basis of sleep is reviewed and the emerging evidence supporting a major role for sleep in learning and memory is described. The bulk of the book focuses on specific sleep disorders associated with aging and age-related neurodegenerative disorders. A comprehensive consideration of this topic is woven through a number of chapters that address both basic research and clinical aspects of sleep abnormalities during aging and in disease. The impact of sleep on the immune system is described. The articles are written in a high level of detail and are comprehensive, thus providing valuable information for a range of scientists and other well-educated people. In particular, the book will be a valuable resource for graduate students, postdoctoral and senior scientists in the fields of sleep, aging, neurodegenerative disorders and learning and memory. In addition, clinicians will find this book valuable as it provides a bridge between basic research and the treatment of the patients with sleep disorders.
