Available in PDF, EPUB and Kindle. Book excerpt: La classification des signes de C.S. Peirce en icones, indices et symboles est universellement reconnue. Est-ce le resultat d'une heureuse rencontre ou la preuve de la pertinence du système de pensée qui l'a produite? Est-ce l'absence d'une présentation scientifique de la sémiotique de Peirce qui autorise cette interrogation? Cet essai montre précisément, au moyen d'une formalisation qui épouse au plus près le contenu des manuscrits de Peirce, la possibilité d'approcher scientifiquement les phénomènes sémiotiques. Partant d'une formalisation de la perception en termes de structures relationnelles, l'auteur réconstruit l'ensemble des conceptions phénoménologiques et sémiotiques de C.S. Peirce, retrouve et discute toutes ses taxinomies et va au-delà en montrant l'existence de structures d'ordre naturelles (treillis) sur les ensembles de classes de signes. Une méthodologie d'analyse des signes complexes en découle et est appliquée notamment a la théâtrologie, l'idéologie, l'épistémologie, l'ethnométhodologie...La semiosis est décrite comme un processus impliquant des communautés humaines par le biais des institutions et des habitus. Une annexe rassemble 76 textes de Peirce définissant le signe dont un grand nombre sont inedits.

Download or read book The Structure of Relation Algebras Generated by Relativizations written by Steven R. Givant and published by American Mathematical Soc.. This book was released on 1994 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foundation of an algebraic theory of binary relations was laid by De Morgan, Peirce, and Schroder during the second half of the nineteenth century. Modern development of the subject as a theory of abstract algebras, called "relation algebras", was undertaken by Tarski and his students. This book aims to analyse the structure of relation algebras that are generated by relativized subalgebras. As examples of their potential for applications, the main results are used to establish representation theorems for classes of relation algebras and to prove existence and uniqueness theorems for simple closures (i.e., for minimal simple algebras containing a given family of relation algebras as relativized subalgebras). This book is well-written and accessible to those who are not specialists in this area. In particular, it contains two introductory chapters on the arithmetic and the algebraic theory of relation algebras. This book is suitable for use in graduate courses onalgebras of binary relations or algebraic logic.

Download or read book Relation Algebras by Games written by Robin Hirsch and published by Elsevier. This book was released on 2002-08-15 with total page 711 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relation algebras are algebras arising from the study of binary relations.They form a part of the field of algebraic logic, and have applications in proof theory, modal logic, and computer science. This research text uses combinatorial games to study the fundamental notion of representations of relation algebras. Games allow an intuitive and appealing approach to the subject, and permit substantial advances to be made. The book contains many new results and proofs not published elsewhere. It should be invaluable to graduate students and researchers interested in relation algebras and games. After an introduction describing the authors' perspective on the material, the text proper has six parts. The lengthy first part is devoted to background material, including the formal definitions of relation algebras, cylindric algebras, their basic properties, and some connections between them. Examples are given. Part 1 ends with a short survey of other work beyond the scope of the book. In part 2, games are introduced, and used to axiomatise various classes of algebras. Part 3 discusses approximations to representability, using bases, relation algebra reducts, and relativised representations. Part 4 presents some constructions of relation algebras, including Monk algebras and the 'rainbow construction', and uses them to show that various classes of representable algebras are non-finitely axiomatisable or even non-elementary. Part 5 shows that the representability problem for finite relation algebras is undecidable, and then in contrast proves some finite base property results. Part 6 contains a condensed summary of the book, and a list of problems. There are more than 400 exercises. The book is generally self-contained on relation algebras and on games, and introductory text is scattered throughout. Some familiarity with elementary aspects of first-order logic and set theory is assumed, though many of the definitions are given. Chapter 2 introduces the necessary universal algebra and model theory, and more specific model-theoretic ideas are explained as they arise.

Available in PDF, EPUB and Kindle. Book excerpt: Digital preservation is an issue faced by practitioners in Ross Harveythe library and recordkeeping professions, yet most professionalshave little time to keep up with the latest techniquesand standards. This invaluable work provides a single-volume introduction to the principles, strategies and practices currently applied by librarians and recordkeepers to the preservation of digital information and will assist them to make informed decisions about the role of digital information in their care. The book is presented in four parts: Why do we preserve? What do we preserve? How do we preserve? and How do we manage digital preservation? Each part covers the area in detail and addresses current issues in a clear and informative manner. The terminology of the field is explained clearly throughout the book. Each chapter includes a range of case studies from institutionsat the forefront of digital object preservation. An index facilitates quick access. This book will be essential as a professional reference tool for all librarians, recordkeepers and archivists with preservation responsibilities as well as being a definitive source of information for the whole profession including students.

Available in PDF, EPUB and Kindle. Book excerpt: The modern theory of algebras of binary relations, reformulated by Tarski as an abstract, algebraic, equational theory of relation algebras, has considerable mathematical significance, with applications in various fields: e.g., in computer science---databases, specification theory, AI---and in anthropology, economics, physics, and philosophical logic. This comprehensive treatment of the theory of relation algebras and the calculus of relations is the first devoted to a systematic development of the subject.
