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.

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.

Book excerpt: Ce livre sur l'algorithmique s'adresse à toute personne désireuse de maîtriser les bases essentielles de la programmation. Pour apprendre à programmer, il faut d'abord comprendre ce qu'est vraiment un ordinateur, comment il fonctionne et surtout comment il peut faire fonctionner des programmes, comment il manipule et stocke les données et les instructions, quelle est sa logique. Alors, au fur et à mesure, le reste devient évidence : variables, tests, conditions, boucles, tableaux, fonctions, fichiers, jusqu'aux notions avancées comme les pointeurs et les objets. Dans ce livre, le langage algorithmique (ou la syntaxe du pseudo-code des algorithmes) reprend celui couramment utilisé dans les écoles d'informatique et dans les formations comme les BTS, DUT, classe préparatoires, premières années d'ingénierie à qui ce livre est en partie destiné et conseillé. Une fois les notions de base acquises, le lecteur trouvera dans ce livre de quoi évoluer vers des notions plus avancées : deux chapitres, l'un sur les pointeurs et les références, l'autre sur les objets, ouvrent les portes de la programmation dans des langages évolués et puissants comme le C, le C++, JAVA et PHP. La plupart des algorithmes de ce livre sont écrits en PHP et les sources, directement utilisables, sont disponibles en téléchargement sur le site de l'éditeur.

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.

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 calculus of relations has been an important component of the development of logic and algebra since the middle of the nineteenth century, when Augustus De Morgan observed that since a horse is an animal we should be able to infer that the head of a horse is the head of an animal. For this, Aristotelian syllogistic does not suffice: We require relational reasoning. George Boole, in his Mathematical Analysis of Logic of 1847, initiated the treatment of logic as part of mathematics, specifically as part of algebra. Quite the opposite conviction was put forward early this century by Bertrand Russell and Alfred North Whitehead in their Principia Mathematica (1910 - 1913): that mathematics was essentially grounded in logic. Logic thus developed in two streams. On the one hand algebraic logic, in which the calculus of relations played a particularly prominent part, was taken up from Boole by Charles Sanders Peirce, who wished to do for the "calculus of relatives" what Boole had done for the calculus of sets. Peirce's work was in turn taken up by Schroder in his Algebra und Logik der Relative of 1895 (the third part of a massive work on the algebra of logic). Schroder's work, however, lay dormant for more than 40 years, until revived by Alfred Tarski in his seminal paper "On the calculus of binary relations" of 1941 (actually his presidential address to the Association for Symbolic Logic).
