Book Description
Computational science can loosely be defined as the endeavor to develop and analyse models for the simulation and control of complex processes. This is achieved by making optimal use of computer resources and by drawing upon a variety of disciplines, techniques and theories. With the emergence of advanced computational and information technologies, computational science now has a significant impact on engineering, physical, biological, management and social sciences. The contributions in this state-of-the-art volume range from theoretical and numerical topics to practical implementations. The subject matter includes modelling, mathematical and numerical analysis, differential equations, linear algebra, optimization, domain decomposition, computational fluid dynamics, computational mechanics, elasticity, structure, computational physics and chemistry, electromagnetic, control theory and other applications. This volume is dedicated to Roland Glowinski on the occasion of his 60th birthday. It is aimed at the next generation of scientists, applied mathematicians, computer scientists, practitioners and engineers who will define computational science within the context of the challenging scientific, industrial, economic and societal problems of the 21st century.

Book Description
This book describes the mathematical background and reviews the techniques for solving problems, including those that require large computations such as transonic flows for compressible fluids and the Navier-Stokes equations for incompressible viscous fluids. Finite element approximations and non-linear relaxation, and nonlinear least square methods are all covered in detail, as are many applications. This volume is a classic in a long-awaited softcover re-edition.
Book Description
Lorsque l'on considère un matériau plastique soumis à des efforts extérieurs, il est nécessaire de connaître le coefficient de charge ultime, c'est-à-dire le multiplicateur λ*qu'il faut appliquer aux efforts pour atteindre la rupture c'est le problème d'Analyse Limite. Grâce à un théorème de R. TEMAN et G. STRANG |22|, la détermination directe de λ* peut se ramener à la minimisation d'une fonctionnelle sous contraintes, que l'on peut ensuite réécrire sous la forme de la recherche d'un point selle du Lagrangien augmenté. Après discrétisation par la méthode des éléments finis, nous avons testé différents algorithmes ·pour la résolution de ce problème. Le calcul classique de λ*utilisait la théorie de la Déformation. Plusieurs calculs étaient alors nécessaires pour encadrer λ*. La comparaison des 2 méthodes a permis de montrer que la première approche fournit un outil bien plus efficace pour la détermination du coefficient de charge ultime (un seul calcul). λ* étant connu, un dernier calcul utilisant la théorie de la Déformation permet de déterminer les zones plastiques, si nécessaire.

Book Description
Persistence theory emerged in the early 2000s as a new theory in the area of applied and computational topology. This book provides a broad and modern view of the subject, including its algebraic, topological, and algorithmic aspects. It also elaborates on applications in data analysis. The level of detail of the exposition has been set so as to keep a survey style, while providing sufficient insights into the proofs so the reader can understand the mechanisms at work. The book is organized into three parts. The first part is dedicated to the foundations of persistence and emphasizes its connection to quiver representation theory. The second part focuses on its connection to applications through a few selected topics. The third part provides perspectives for both the theory and its applications. The book can be used as a text for a course on applied topology or data analysis.

Book Description
This book presents the chemical properties of lignocellulosic fibers, knowledge of which is essential for innovation and sustainable development of their transformation. Thermochemical transformation of wood and other lignocellulosics is presented to highlight its volatile, liquid and solid products and their novel applications. Forest biorefinery is described to emphasize the new products from lignocellulosic constituents, both structural (cellulose, hemicelluloses and lignins) and those extraneous to cell walls-extractives. New developments in cellulose technology related to nanocellulose are discussed in relation to new applications. Industrial lignins are presented in detail, both in terms of extraction procedures from spent liquors and structural characterization of the isolated lignins. Application of lignocellulosic biopolymers in new composite materials, or in biomaterials for medicinal purposes, and in solid wood preservation, are described. The example of an industrial biorefinery installed in southwestern France more than 40 years ago is presented.
