Book Synopsis Inconsistency Robustness by : Carl Hewitt
Download or read book Inconsistency Robustness written by Carl Hewitt and published by . This book was released on 2015-05-20 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inconsistency robustness is information system performance in the face of continually pervasive inconsistencies---a shift from the previously dominant paradigms of inconsistency denial and inconsistency elimination attempting to sweep them under the rug. Inconsistency robustness is a both an observed phenomenon and a desired feature: Inconsistency Robustness is an observed phenomenon because large information-systems are required to operate in an environment of pervasive inconsistency. Inconsistency Robustness is a desired feature because we need to improve the performance of large information system. This volume has revised versions of refereed articles and panel summaries from the first two International Symposia on Inconsistency Robustness conducted under the auspices of the International Society for Inconsistency Robustness (iRobust http: //irobust.org). The articles are broadly based on theory and practice, addressing fundamental issues in inconsistency robustness. The field of Inconsistency Robustness aims to provide practical rigorous foundations for computer information systems dealing with pervasively inconsistent information."

Download or read book Effective Methods in Algebraic Geometry written by Teo Mora and published by Springer Science & Business Media. This book was released on 1991 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium "MEGA-90 - Effective Methods in Algebraic Geome try" was held in Castiglioncello (Livorno, Italy) in April 17-211990. The themes - we quote from the "Call for papers" - were the fol lowing: - Effective methods and complexity issues in commutative algebra, pro jective geometry, real geometry, algebraic number theory - Algebraic geometric methods in algebraic computing Contributions in related fields (computational aspects of group theory, differential algebra and geometry, algebraic and differential topology, etc.) were also welcome. The origin and the motivation of such a meeting, that is supposed to be the first of a series, deserves to be explained. The subject - the theory and the practice of computation in alge braic geometry and related domains from the mathematical viewpoin- has been one of the themes of the symposia organized by SIGSAM (the Special Interest Group for Symbolic and Algebraic Manipulation of the Association for Computing Machinery), SAME (Symbolic and Algebraic Manipulation in Europe), and AAECC (the semantics of the name is vary ing; an average meaning is "Applied Algebra and Error Correcting Codes").
Book Synopsis Computer Algebra and Polynomials by : Jaime Gutierrez
Download or read book Computer Algebra and Polynomials written by Jaime Gutierrez and published by Springer. This book was released on 2015-01-20 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algebra and number theory have always been counted among the most beautiful mathematical areas with deep proofs and elegant results. However, for a long time they were not considered that important in view of the lack of real-life applications. This has dramatically changed: nowadays we find applications of algebra and number theory frequently in our daily life. This book focuses on the theory and algorithms for polynomials over various coefficient domains such as a finite field or ring. The operations on polynomials in the focus are factorization, composition and decomposition, basis computation for modules, etc. Algorithms for such operations on polynomials have always been a central interest in computer algebra, as it combines formal (the variables) and algebraic or numeric (the coefficients) aspects. The papers presented were selected from the Workshop on Computer Algebra and Polynomials, which was held in Linz at the Johann Radon Institute for Computational and Applied Mathematics (RICAM) during November 25-29, 2013, at the occasion of the Special Semester on Applications of Algebra and Number Theory.

Available in PDF, EPUB and Kindle. Book excerpt: Dans les milieux industriels du secteur automobile, aéronautique, aérospatial, etc., la mise en forme des matériaux au cours du processus de fabrication a un impact sur la qualité et le coût du produit final. Cet ouvrage présente les différents procédés utilisés en industrie lors de la phase de la mise en forme qui est déterminante : emboutissage, hydroformage et fabrication additive. Il propose une modélisation de ces derniers à travers les avancées théoriques et numériques de chaque procédé en passant par la mécanique des grandes déformations à la base des grandes transformations. Les différentes techniques relatives à l'optimisation et le calcul de fiabilité des différents procédés sont également abordés. Pédagogique, Mise en forme des matériaux met en perspective les enjeux qui se nouent autour de la modernisation de ces procédés : diminution de la durée du cycle de développement des produits, amélioration de la qualité des produits et fiabilisation des procédés, optimisation de la réalisation des essais avec réduction de leur coût et simulation des phénomènes complexes non reproductibles par des essais.
Book Synopsis Etude de la mise en forme par compression des Sheet Molding Compounds by : Steven Le Corre
Download or read book Etude de la mise en forme par compression des Sheet Molding Compounds written by Steven Le Corre and published by Presses Academiques Francophones. This book was released on 2014-12-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce document est une contribution a l'etude du procede de mise en forme des SMC, travail destine a fournir les bases d'un outil de simulation permettant de predire la separation fibres/matrice lors du remplissage des moules. Ainsi, le travail s'articule autour de la construction d'un modele biphasique base sur la theorie des melanges, ou le SMC est vu comme la superposition de deux milieux continus complementaires: le milieu fibres et le milieu pate. La construction du modele s'appuie sur des caracterisations experimentales sous sollicitations homogenes. Les trois dispositifs developpes permettent de quantifier les effets de la vitesse de deformation, de la temperature et du taux de fibres sur la rheologie de ces materiaux. Le milieu pate, deduit des experiences, est assimile a un fluide en loi puissance compressible. Le comportement du milieu fibres est obtenu par homogeneisation de structures discretes, ce qui permet d'identifier un modele de fluide orthotrope en loi puissance micro-macro. La derniere partie de l'ouvrage est dediee a l'ecriture d'un modele biphasique simplifie qui permet de se ramener a un modele coque qui sera implante dans un code de simulation numerique.
Book Synopsis Du modèle à la simulation informatique by : Franck Varenne
Download or read book Du modèle à la simulation informatique written by Franck Varenne and published by Vrin. This book was released on 2007 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avec l'evolution recente des modeles mathematiques vers des simulations informatiques, les formalisations du vivant sont de plus en plus integratives, mixtes et, en un sens, realistes. Plus generalement, les formalisations d'objets complexes deviennent assises sur et non plus seulement traitees par l'infrastructure informatique. Quelle est la veritable portee epistemologique de cette empirie simulee? Comment la distinguer de la creativite proprement interne aux mathematiques dont la philosophie des sciences a deja su rendre compte? En se penchant sur les modeles de plantes, cette enquete historique et epistemologique montre comment une telle evolution bouleverse les epistemologies contemporaines des formalisations et des modeles (dont l'iconoclasme epistemologique si vivace au XXe siecle) en renouvelant d'une part la question des rapports entre mathematiques, calcul, langage informatique et replication, et d'autre part la question de l'integration, dans un objet formel commun, de savoirs disciplinaires distincts.
Book Synopsis Simulation de la mise en forme de renforts NCF de composites basée sur des approches mesoscopiques by : Ruochen Zheng
Download or read book Simulation de la mise en forme de renforts NCF de composites basée sur des approches mesoscopiques written by Ruochen Zheng and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pour parvenir à une fabrication efficace et exempte de défauts de renforts fibreux tout en minimisant la nécessité de tests expérimentaux longs et coûteux, il est nécessaire de développer des techniques de simulation et d'optimisation fiables du procédé de mise en forme. Les renforts composites NCF (Non-Crimp Fabric) promettent des performances structurales exceptionnelles, mais la mise en forme de ces matériaux est délicate. Sa complexité découle des mécanismes de déformation spécifiques de ce type de renforts, principalement influencés par les motifs de couture complexes qui lient subtilement les fibres entre elles. Dans cette étude, nous proposons une approche de modélisation par éléments finis à l'échelle mésoscopique pour relever ce défi. Ici, nous traitons les mèches comme un milieu continu, tandis que les coutures environnantes sont soigneusement représentées à l'aide d'éléments poutres. Pour capturer les caractéristiques de déformation des mèches, nous utilisons une loi hyperélastique, complétée par des éléments poutres intégrés pour découpler leur comportement en flexion. De plus, nous introduisons une étape de précontrainte pour simuler la tension due au tricotage des coutures et modéliser l'interaction complexe entre les mèches et les coutures, en tenant compte des mécanismes de glissement propre aux matériaux NCF. La crédibilité de notre modèle est attestée par des simulations de déformation en cisaillement dans le plan sur une cellule unitaire et des tests de cisaillement en bias-extension. Ces simulations mettent en évidence la polyvalence du modèle mésoscopique, permettant la caractérisation virtuelle des matériaux et réduisant les efforts expérimentaux généralement requis pour les simulations macroscopiques. De plus, notre approche offre des descriptions explicites des mèches et des coutures basées sur des observations en tomographie et générées à l'aide d'équations paramétriques. Cette fonctionnalité permet l'analyse de différents motifs de couture et de structures de tissu, offrant des opportunités de personnaliser les matériaux NCF avec un comportement de déformation optimisé pour des applications spécifiques. Conscient que le changement d'orientation des fibres influence considérablement le comportement mécanique de la pièce composite finale après l'étape de mise en forme, une méthode de post-traitement est proposée sur ce modèle mésoscopique pour suivre la direction des fibres et visualiser l'angle de cisaillement. Un avantage notable de notre approche de modélisation mésoscopique réside dans sa capacité à détecter et à analyser les défauts locaux, tels que le gapping, un défaut majeur dans la mise en forme des NCF difficile à observer directement via des simulations macroscopiques. Par conséquent, le modèle mésoscopique permet l'analyse et la prédiction de la formation et du développement des défauts du gapping, contribuant à améliorer la qualité et l'efficacité de la fabrication.

In this book a review of the basics of the technique is made, together with different examples of application.
Book Synopsis Finite Element Method Simulation of 3D Deformable Solids by : Eftychios Sifakis
Download or read book Finite Element Method Simulation of 3D Deformable Solids written by Eftychios Sifakis and published by Springer Nature. This book was released on 2022-06-01 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a practical guide to simulation of 3D deformable solids using the Finite Element Method (FEM). It reviews a number of topics related to the theory and implementation of FEM approaches: measures of deformation, constitutive laws of nonlinear materials, tetrahedral discretizations, and model reduction techniques for real-time simulation. Simulations of deformable solids are important in many applications in computer graphics, including film special effects, computer games, and virtual surgery. The Finite Element Method has become a popular tool in many such applications. Variants of FEM catering to both offline and real-time simulation have had a mature presence in computer graphics literature. This book is designed for readers familiar with numerical simulation in computer graphics, who would like to obtain a cohesive picture of the various FEM simulation methods available, their strengths and weaknesses, and their applicability in various simulation scenarios. The book is also a practical implementation guide for the visual effects developer, offering a lean yet adequate synopsis of the underlying mathematical theory. Chapter 1 introduces the quantitative descriptions used to capture the deformation of elastic solids, the concept of strain energy, and discusses how force and stress result as a response to deformation. Chapter 2 reviews a number of constitutive models, i.e., analytical laws linking deformation to the resulting force that has successfully been used in various graphics-oriented simulation tasks. Chapter 3 summarizes how deformation and force can be computed discretely on a tetrahedral mesh, and how an implicit integrator can be structured around this discretization. Finally, chapter 4 presents the state of the art in model reduction techniques for real-time FEM solid simulation and discusses which techniques are suitable for which applications. Topics discussed in this chapter include linear modal analysis, modal warping, subspace simulation, and domain decomposition.
