This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les méthodes formelles ont pour objectif d'augmenter le niveau de confiance que l'on peut avoir en un système informatique, en proposant des techniques d'analyse dont les fondements sont mathématiques. Traditionnellement, ces méthodes sont classées en trois grandes familles : le model-checking, la preuve interactive et le test. Ce mémoire décrit le développement d'un environnement formel qui autorise à la fois une activité de vérification et dont l'objectif est permettre l'étude de systèmes complexes modélisés sous la forme d'automates. Cet environnement prend la forme d'un ensemble de théories Isabelle/HOL dont la racine est formée par la formalisation des systèmes de transitions et leur comportements. Plusieurs mécanismes de preuve sont présentés et il est mit en évidence l'importance du mécanisme de réécritures. Nous nous intéressons également à une nouvelle approche du test qui consiste à envisager la création d'un test comme la démonstration d'un énoncé.

Book excerpt: Nos travaux étudient la conception du test en complément de preuves : l'objectif est de définir des critères de sélection de test qui ciblent les lacunes de ces preuves. Le champ d'application proposé est la vérification d'algorithmes de tolérance aux fautes. Les preuves considérées peuvent être des démonstrations informelles, publiées dans la littérature, ou des preuves formelles inachevées. Dans le premier cas, nous définissons une méthode basée sur une reformulation du discours informel sous forme d'un arbre de preuve. L'arbre offre une représentation de l'articulation logique de la démonstration, ainsi qu'un support pour son analyse pas à pas. La faisabilité et l'efficacité du test guidé par la preuve sont évaluées expérimentalement sur deux exemples d'algorithmes incorrects : un algorithme d'ordonnancement de tâches, et un algorithme d'appartenance de groupe. Les résultats montrent que l'identification des lacunes de la preuve peut s'avérer efficace pour guider le test, sous réserve que l'analyse de l'arbre ne mette pas en évidence un manque de rigueur affectant l'ensemble de la démonstration. Dans le cas de preuves formelles, nous reprenons le principe d'un test basé sur l'arbre de preuve. L'établissement d'un lien entre les lemmes non prouvés et des sous-espaces d'entrée de test peut alors être plus problématique que précédemment. L'étude expérimentale d'un autre algorithme d'appartenance de groupe, partiellement prouvé avec le système PVS, montre néanmoins que, lorsqu'un lien est possible, cette information peut s'avérer pertinente pour guider le test.

Book Synopsis Certified Programming with Dependent Types by : Adam Chlipala
Download or read book Certified Programming with Dependent Types written by Adam Chlipala and published by MIT Press. This book was released on 2013-12-06 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: A handbook to the Coq software for writing and checking mathematical proofs, with a practical engineering focus. The technology of mechanized program verification can play a supporting role in many kinds of research projects in computer science, and related tools for formal proof-checking are seeing increasing adoption in mathematics and engineering. This book provides an introduction to the Coq software for writing and checking mathematical proofs. It takes a practical engineering focus throughout, emphasizing techniques that will help users to build, understand, and maintain large Coq developments and minimize the cost of code change over time. Two topics, rarely discussed elsewhere, are covered in detail: effective dependently typed programming (making productive use of a feature at the heart of the Coq system) and construction of domain-specific proof tactics. Almost every subject covered is also relevant to interactive computer theorem proving in general, not just program verification, demonstrated through examples of verified programs applied in many different sorts of formalizations. The book develops a unique automated proof style and applies it throughout; even experienced Coq users may benefit from reading about basic Coq concepts from this novel perspective. The book also offers a library of tactics, or programs that find proofs, designed for use with examples in the book. Readers will acquire the necessary skills to reimplement these tactics in other settings by the end of the book. All of the code appearing in the book is freely available online.
Book Synopsis Semi-Infinite Programming by : Rembert Reemtsen
Download or read book Semi-Infinite Programming written by Rembert Reemtsen and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-infinite programming (briefly: SIP) is an exciting part of mathematical programming. SIP problems include finitely many variables and, in contrast to finite optimization problems, infinitely many inequality constraints. Prob lems of this type naturally arise in approximation theory, optimal control, and at numerous engineering applications where the model contains at least one inequality constraint for each value of a parameter and the parameter, repre senting time, space, frequency etc., varies in a given domain. The treatment of such problems requires particular theoretical and numerical techniques. The theory in SIP as well as the number of numerical SIP methods and appli cations have expanded very fast during the last years. Therefore, the main goal of this monograph is to provide a collection of tutorial and survey type articles which represent a substantial part of the contemporary body of knowledge in SIP. We are glad that leading researchers have contributed to this volume and that their articles are covering a wide range of important topics in this subject. It is our hope that both experienced students and scientists will be well advised to consult this volume. We got the idea for this volume when we were organizing the semi-infinite pro gramming workshop which was held in Cottbus, Germany, in September 1996.

Book excerpt: This textbook presents the core of recent advances in design theory and its implications for design methods and design organization. Providing a unified perspective on different design methods and approaches, from the most classic (systematic design) to the most advanced (C-K theory), it offers a unique and integrated presentation of traditional and contemporary theories in the field. Examining the principles of each theory, this guide utilizes numerous real life industrial applications, with clear links to engineering design, industrial design, management, economics, psychology and creativity. Containing a section of exams with detailed answers, it is useful for courses in design theory, engineering design and advanced innovation management. "Students and professors, practitioners and researchers in diverse disciplines, interested in design, will find in this book a rich and vital source for studying fundamental design methods and tools as well as the most advanced design theories that work in practice". Professor Yoram Reich, Tel Aviv University, Editor-in-Chief, Research In Engineering Design. "Twenty years of research in design theory and engineering have shown that training in creative design is indeed possible and offers remarkably operational methods - this book is indispensable for all leaders and practitioners who wish to strengthen theinnovation capacity of their company." Pascal Daloz, Executive Vice President, Dassault Systèmes

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Synopsis Adaptive Stream Mining by : Albert Bifet
Download or read book Adaptive Stream Mining written by Albert Bifet and published by IOS Press. This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.

Book Synopsis Signal Processing for Communications by : Paolo Prandoni
Download or read book Signal Processing for Communications written by Paolo Prandoni and published by Collection Savoir suisse. This book was released on 2008-06-17 with total page 392 pages. 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.
