This book was released on 2007 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objectif de cette recherche doctorale a été d'estimer la soudabilité par laser des matériaux polymériques en fonction de leurs propriétés thermo-physiques. La première tâche, dans la recherche de cet objectif, a été de quantifier l'atténuation de la radiation dans les polymères semi-transparents en établissant la corrélation entre les propriétés optiques des inclusions et de la matrice du polymère, et la distribution spatiale de l'intensité laser les traversant, c'est à dire, en effectuant une modélisation des phénomènes optiques qui permet d’estimer la forme de la distribution du faisceau laser à l’interface des deux matériaux. Cette modélisation a permis aussi de découpler les facteurs influents et d’explorer leurs effets sur l’atténuation et l’élargissement du faisceau laser à travers un milieu semi transparent. L’étape suivante consiste à réaliser le couplage entre le modèle optique et le modèle thermique, fondé sur l’équation de la diffusion de la chaleur, afin de déterminer les champs de températures dans le volume des composants. Cette étude constitue une ouverture vers l’approche scientifique des processus de soudage par laser des thermoplastiques en offrant des méthodes et des techniques pour l’optimisation globale de ceux-ci.

Download or read book Chemistry and Analysis of Volatile Organic Compounds in the Environment written by H.J. Bloemen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the occurrence and behaviour of volatile organic compounds (VOCs) is increasing due to their adverse effects on the environment and human health. It is essential that information is made available on the various aspects of research on VOCs to enable better understanding and control of the various environmental and human health threats. The information in this book will be used to improve communication and understanding of the various approaches. In particular the potential and limitations of the described analytical methods will be essential in defining environmental studies and interpreting the results.

Available in PDF, EPUB and Kindle. Book excerpt: The artificial intelligence (AI) landscape has evolved significantly from 1950 when Alan Turing first posed the question of whether machines can think. Today, AI is transforming societies and economies. It promises to generate productivity gains, improve well-being and help address global challenges, such as climate change, resource scarcity and health crises.
Download or read book Ordered and Turbulent Patterns in Taylor Couette Flow written by C. David Andereck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seldom does a physical system, particularly one as apparently simple as the flow of a Newtonian fluid between concentric rotating cylinders, retain the interest of scientists, applied mathematicians and engineers for very long. Yet, as this volume goes to press it has been nearly 70 years since G. I. Taylor's outstanding experimental and theoretical study of the linear stability of this flow was published, and a century since the first experiments were performed on rotating cylinder viscometers. Since then, the study of this system has progressed enormously, but new features of the flow patterns are still being uncovered. Interesting variations on the basic system abound. Connections with open flows are being made. More complex fluids are used in some experiments. The vigor of the research going on in this particular example of nonequilibrium systems was very apparent at the NATO Advanced Research Workshop on "Ordered and Turbulent Patterns in Taylor Couette Flow," held in Columbus, Ohio, USA May 22-24, 1991. A primary goal of this ARW was to bring together those interested in pattern formation in the classic Taylor Couette problem with those looking at variations on the basic system and with those interested in related systems, in order to better define the interesting areas for the future, the open questions, and the features common (and not common) to closed and open systems. This volume contains many of the contributions presented during the workshop.
Download or read book Science and Application of Nanotubes written by D. Tománek and published by Springer Science & Business Media. This book was released on 2005-12-17 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series of books, which is published at the rate of about one per year, addresses fundamental problems in materials science. The contents cover a broad range of topics from small clusters of atoms to engineering materials and involve chemistry, physics, materials science, and engineering, with length scales ranging from Ångstroms up to millimeters. The emphasis is on basic science rather than on applications. Each book focuses on a single area of current interest and brings together leading experts to give an up-to-date discussion of their work and the work of others. Each article contains enough references that the interested reader can access the relevant literature. Thanks are given to the Center for Fundamental Materials Research at Michigan State University for supporting this series. M. F. Thorpe, Series Editor E-mail: thorpe@pa. msu. edu East Lansing, Michigan V PREFACE It is hard to believe that not quite ten years ago, namely in 1991, nanotubes of carbon were discovered by Sumio Iijima in deposits on the electrodes of the same carbon arc apparatus that was used to produce fullerenes such as the “buckyball”. Nanotubes of carbon or other materials, consisting ofhollow cylinders that are only a few nanometers in diameter, yet up to millimeters long, are amazing structures that self-assemble under extreme conditions. Their quasi-one-dimensional character and virtual absence of atomic defects give rise to a plethora of unusual phenomena.

Download or read book Tamara de Lempicka written by Gioia Mori and published by . This book was released on 2024-10-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A landmark retrospective on the Art Deco painter exploring her intersectional identities Tamara de Lempicka (1894-1980), the "Baroness with a Brush," is often cast as one of Art Deco's most celebrated artists, though her work transcends categorization, incorporating elements of Cubism and Neoclassicism in a distinctive, sensuous blend of form and function. Lempicka's paintings, including a self-portrait as the driver of a sleek green Bugatti, often depict dazzling, self-assured women, exuding elegance and transgressive sexuality while combining the modern with the classical. This gorgeous survey presents the full arc of Lempicka's career in the context of her life and her evolving identity, including her Polish and Russian origins, her marriages and other relationships, and her time in France, Italy, and the United States. This book unfolds chronologically through three sections that mark the stages of the artist's life and the evolution of her artistic style, with particular focus on her Jewish heritage, her expression of gender, and her sexuality.
