Ce livre sur l'algèbre relationnelle et la conception d'une base de données est un guide pratique qui décrit différentes étapes, pas à pas et avec de nombreux exemples, de l'expression des besoins des utilisateurs à la conception d'une base de données relationnelle normalisée qui répond à leur demande. C'est un ouvrage qui peut être lu, compris et mis en pratique par tout public : débutant, étudiant en informatique mais aussi professionnel de l'informatique ou enseignant. Tout au long des chapitres, la base de données sera positionnée dans le Système d'Information puis les sujets suivants seront décrits et mis en pratique : le dictionnaire des données de l'entreprise, la Matrice des Dépendances Fonctionnelles, les modèles et plus particulièrement les modèles de données de la méthode Merise (dont le modèle Conceptuel de Données), les règles de passage de la Matrice des Dépendances Fonctionnelles au schéma entités-associations puis à la Base de Données Relationnelle, les concepts fondamentaux de l'algèbre relationnelle, les opérateurs de l'algèbre relationnelle pour répondre aux requêtes des utilisateurs, la normalisation des relations... Après la lecture de ce livre, le lecteur sera capable de modéliser conceptuellement une base de données relationnelle et d'interroger les données de cette base en utilisant les opérateurs de l'algèbre relationnelle. Le processus développé dans le livre peut être mis en pratique facilement et avec succès dans la vie professionnelle. Des compléments à cet ouvrage (arbres algébriques de l'étude de cas, exercices sur les formes normales, exercices d'utilisation d'opérateurs algébriques...) sont en téléchargement sur www.editions-eni.fr/livres.

This textbook provides a comprehensive and instructive coverage of vehicular traffic flow dynamics and modeling. It makes this fascinating interdisciplinary topic, which to date was only documented in parts by specialized monographs, accessible to a broad readership. Numerous figures and problems with solutions help the reader to quickly understand and practice the presented concepts. This book is targeted at students of physics and traffic engineering and, more generally, also at students and professionals in computer science, mathematics, and interdisciplinary topics. It also offers material for project work in programming and simulation at college and university level. The main part, after presenting different categories of traffic data, is devoted to a mathematical description of the dynamics of traffic flow, covering macroscopic models which describe traffic in terms of density, as well as microscopic many-particle models in which each particle corresponds to a vehicle and its driver. Focus chapters on traffic instabilities and model calibration/validation present these topics in a novel and systematic way. Finally, the theoretical framework is shown at work in selected applications such as traffic-state and travel-time estimation, intelligent transportation systems, traffic operations management, and a detailed physics-based model for fuel consumption and emissions.

Gathered together in this book are the fundamental texts of the great classical period in modern logic. A complete translation of Gottlob Frege's "Begriffsschrift"--which opened a great epoch in the history of logic by fully presenting propositional calculus and quantification theory--begins the volume. The texts that follow depict the emergence of set theory and foundations of mathematics, two new fields on the borders of logic, mathematics, and philosophy. Essays trace the trends that led to "Principia mathematica," the appearance of modern paradoxes, and topics including proof theory, the theory of types, axiomatic set theory, and Lowenheim's theorem. The volume concludes with papers by Herbrand and by Godel, including the latter's famous incompleteness paper."

Why are certain methods of punishment adopted or rejected in a given social situation? To what extent is the development of penal methods determined by basic social relations? The answers to these questions are complex, and go well beyond the thesis that institutionalized punishment is simply for the protection of society. While today's punishment of offenders often incorporates aspects of psychology, psychiatry, and sociology, at one time there was a more pronounced difference in criminal punishment based on class and economics. Punishment and Social Structure originated from an article written by Georg Rusche in 1933 entitled "Labor Market and Penal Sanction: Thoughts on the Sociology of Criminal Justice." Originally published in Germany by the Frankfurt Institute of Social Research, this article became the germ of a theory of criminology that laid the groundwork for all subsequent research in this area. Rusche and Kirchheimer look at crime from an historical perspective, and correlate methods of punishment with both temporal cultural values and economic conditions. The authors classify the history of crime into three primary eras: the early Middle Ages, in which penance and fines were the predominant modes of punishment; the later Middle Ages, in which harsh corporal punishment and capital punishment moved to the forefront; and the seventeenth century, in which the prison system was more fully developed. They also discuss more recent forms of penal practice, most notably under the constraints of a fascist state. The majority of the book was translated from German into English, and then reshaped by Rusche's co-author, Otto Kirchheimer, with whom Rusche actually had little discussion. While the main body of Punishment and Social Structure are Rusche's ideas, Kirchheimer was responsible for bringing the book more up-to-date to include the Nazi and fascist era. Punishment and Social Structure is a pioneering work that sets a paradigm for the study of crime and punishment.
