This book was released on 1986 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: La mise en œuvre d’un système MUMPS autonome sur la machine multimicroprocesseur SM90 nous a permis de dégager certaines fonctionnalités, associées aux niveaux conceptuel et interne des SGBD, qui s’avèrent particulièrement utiles comme outils pour l’écriture de SGBD. Le noyau principal de ces outils réside dans l’intégration d’une organisation hiérarchique et dynamique de données dans le langage MUPS accessible à partir de la notion de variable globale. La modélisation des informations permet l’usage du système MUMPS dans un contexte de base de données relationnelles et en logique : l’espace de stockage directement accessible à travers le langage est celui des disques du système. Une extension du langage est proposée sous la forme d’une fonction pour l’interrogation et le parcours de l’espace global. Nous montrons une utilisation de l’espace global en déduction dans le cadre d’une interrogation basée sur la logique. La représentation de faits élémentaires, de règles dans une base de connaissances s’expriment à travers la notion de variable globale. L’adjonction de potentialités graphiques au systèmes MUMPS par l’apport d’un coprocesseur spécialisé permet d’envisager la réalisation d’interfaces graphiques de haut niveau. Enfin nous montrons que l’évolution du concept de base de données est lié à sa capacité à manipuler de nouveaux types d’objets, principalement les types graphique et image.

This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Le travail réalisé comprend une étude critique sur la structure de base des langages d'interrogation et leurs caractéristiques linguistiques (abrévation, vocabulaire et syntaxe). Une réflexion est faite sur les différents types d'utilisateurs pour comprendre les facteurs humains qui influencent leur comportement en face d'un système informatisé. A partir de là, nous avons défini l'utilisateur occasionnel visé par l'interface et un langage de commande (Lasydo) lui est adapté. Les caractéristiques de ce langage, ses fonctions et ses éléments sont discutés. Un traducteur ayant la structure de compilateur assure la transformation de la requête de l'usager en une forme acceptee par SGDB. Nous utilisons dans ce but un logiciel d'aide à l'écriture des traducteurs. La structure interne de Lasydo et celle de la base de données y sont prises en considération. Ce traducteur est défini et réalisé. Une étude synthétique et comparative sur les modèles de données à débouché sur la mise en oeuvre d'une base de données selon le modèle relationnel. En exploitant les propriétés de ce modèle, nous proposons deux schémas de la base, à relation unique et à relations multiples. Nous discutons la représentation de ces schémas sous forme de graphe extensible et nous décrivons le mécanisme de edéduction des chemins d'accès à l'information recherchée. Enfin, l'implantation de la base et de l'interface (modulaire et extensible) sous le système multics du HB68 est décrite.

Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.

Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Information Technology explores the familiar devices that we use to collect, transform, transmit, and interact with electronic information. Many such devices operate surprisingly close to very many fundamental physical limits. Understanding how such devices work, and how they can (and cannot) be improved, requires deep insight into the character of physical law as well as engineering practice. The book starts with an introduction to units, forces, and the probabilistic foundations of noise and signalling, then progresses through the electromagnetics of wired and wireless communications, and the quantum mechanics of electronic, optical, and magnetic materials, to discussions of mechanisms for computation, storage, sensing, and display. This self-contained volume will help both physical scientists and computer scientists see beyond the conventional division between hardware and software to understand the implications of physical theory for information manipulation.

Book excerpt: Quantum information and computation is a rapidly expanding and cross-disciplinary subject. This book, first published in 2006, gives a self-contained introduction to the field for physicists, mathematicians and computer scientists who want to know more about this exciting subject. After a step-by-step introduction to the quantum bit (qubit) and its main properties, the author presents the necessary background in quantum mechanics. The core of the subject, quantum computation, is illustrated by a detailed treatment of three quantum algorithms: Deutsch, Grover and Shor. The final chapters are devoted to the physical implementation of quantum computers, including the most recent aspects, such as superconducting qubits and quantum dots, and to a short account of quantum information. Written at a level suitable for undergraduates in physical sciences, no previous knowledge of quantum mechanics is assumed, and only elementary notions of physics are required. The book includes many short exercises, with solutions available to instructors through [email protected].

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume offers readers a progressive and highly detailed introduction to the complex behavior of neutrons in general, and in the context of nuclear power generation. A compendium and handbook for nuclear engineers, a source of teaching material for academic lecturers as well as a graduate text for advanced students and other non-experts wishing to enter this field, it is based on the author’s teaching and research experience and his recognized expertise in nuclear safety. After recapping a number of points in nuclear physics, placing the theoretical notions in their historical context, the book successively reveals the latest quantitative theories concerning: • The slowing-down of neutrons in matter • The charged particles and electromagnetic rays • The calculation scheme, especially the simplification hypothesis • The concept of criticality based on chain reactions • The theory of homogeneous and heterogeneous reactors • The problem of self-shielding • The theory of the nuclear reflector, a subject largely ignored in literature • The computational methods in transport and diffusion theories Complemented by more than 400 bibliographical references, some of which are commented and annotated, and augmented by an appendix on the history of reactor physics at EDF (Electricité De France), this book is the most comprehensive and up-to-date introduction to and reference resource in neutronics and reactor theory.

Book excerpt: NOTE: This edition features the same content as the traditional text in a convenient, three-hole-punched, loose-leaf version. Books a la Carte also offer a great value--this format costs significantly less than a new textbook. Before purchasing, check with your instructor or review your course syllabus to ensure that you select the correct ISBN. Several versions of Pearson's MyLab & Mastering products exist for each title, including customized versions for individual schools, and registrations are not transferable. In addition, you may need a CourseID, provided by your instructor, to register for and use Pearson's MyLab & Mastering products. xxxxxxxxxxxxxxx For courses in linear algebra.This package includes MyMathLab(R). With traditional linear algebra texts, the course is relatively easy for students during the early stages as material is presented in a familiar, concrete setting. However, when abstract concepts are introduced, students often hit a wall. Instructors seem to agree that certain concepts (such as linear independence, spanning, subspace, vector space, and linear transformations) are not easily understood and require time to assimilate. These concepts are fundamental to the study of linear algebra, so students' understanding of them is vital to mastering the subject. This text makes these concepts more accessible by introducing them early in a familiar, concrete "Rn" setting, developing them gradually, and returning to them throughout the text so that when they are discussed in the abstract, students are readily able to understand. Personalize learning with MyMathLabMyMathLab is an online homework, tutorial, and assessment program designed to work with this text to engage students and improve results. MyMathLab includes assignable algorithmic exercises, the complete eBook, interactive figures, tools to personalize learning, and more.
