Book excerpt: GRACE AU DEVELOPPEMENT IMPORTANT DES MOYENS INFORMATIQUES DE CALCULS, DES SIMULATIONS NUMERIQUES D'IMPACTS HYDRODYNAMIQUES DEVIENNENT ENVISAGEABLES AUJOURD'HUI, SIMULATIONS DONT LE NIVEAU DE COMPLEXITE EST LIE A LA NATURE DES RESULTATS SOUHAITES. LEUR PRINCIPALE DIFFICULTE RESIDE DANS LA MODELISATION DES INTERACTIONS ENTRE FLUIDE ET STRUCTURE, DANS LE CAS D'UN REGIME DE DYNAMIQUE RAPIDE TRANSITOIRE. LA CONNAISSANCE DU COMPORTEMENT STRUCTURAL DU CORPS N'APPARAIT PLUS COMME UN OBSTACLE AUJOURD'HUI ; LES CODES DE CALCULS PERMETTENT DES SIMULATIONS TRES PRECISES D'ECRASEMENT DE STRUCTURES, POUVANT INCLURE DES RUPTURES COMPLEXES. DE MEME, LA MODELISATION DES ECOULEMENTS DE FLUIDE ATTEINT DES NIVEAUX DE PRECISION ELEVES. IL RESTE DONC A MODELISER L'INFLUENCE D'UN MILIEU SUR L'AUTRE. LE BUT DE CETTE ETUDE EST LA PREVISION DU COMPORTEMENT D'UN CORPS IMPACTANT LE FLUIDE ; ELLE EST DONC CONCENTREE SUR LA CONNAISSANCE DE SES MOUVEMENTS ET DE SES DEFORMATIONS LOCALES. LA METHODE NUMERIQUE CHOISIE A DONC PRIVILEGIE LA MODELISATION STRUCTURALE, PLUTOT QUE CELLE DE L'ECOULEMENT, CAR SEULE LA SOLLICITATION EN PRESSION DU FLUIDE EST ESSENTIELLE. POUR CETTE RAISON, UNE APPROCHE DE TYPE ELEMENTS FINIS, DEVELOPPEE POUR L'ETUDE DE STRUCTURES SOUPLES COMPLEXES EST ADOPTEE, EN PREFERENCE A DES METHODES DE TYPE INTEGRALES OU MASSES AJOUTEES. CE TRAVAIL DE RECHERCHE A POUR OBJECTIF DE METTRE EN EVIDENCE LES POTENTIALITES, LES LIMITES ET LE COUT D'EXPLOITATION D'UNE TELLE METHODE A MODELISER UN IMPACT SUR L'EAU D'UNE STRUCTURE SOUPLE, TANT POUR UNE FORMULATION LAGRANGIENNE QUE ALE. APRES L'EVOCATION DU CONTEXTE INDUSTRIEL, CETTE ETUDE S'ARTICULE DONC AUTOUR, D'UNE PART, DE LA MODELISATION MATHEMATIQUE ET DE LA RESOLUTION NUMERIQUE DE CE TYPE D'IMPACT ET D'AUTRE PART, DE LA VALIDATION D'UNE MEF EXPLICITE DE DYNAMIQUE RAPIDE, SUIVIE D'UNE APPLICATION A UN CAS INDUSTRIEL

Book excerpt: In this work, begun during the German occupation, the eminent French poet and philosopher began to turn away from the small, perfect poem toward a much more open form, a kind of prose poem that recounted its own process of coming into being along with the final result.

Download or read book Radical Coherency written by David Antin and published by University of Chicago Press. This book was released on 2012-03-15 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: “We got to talking”—so David Antin begins the introduction to Radical Coherency, embarking on the pursuit that has marked much of his breathless, brilliantly conversational work. For the past forty years, whether spoken under the guise of performance artist or poet, cultural explorer or literary critic, Antin’s innovative observations have helped us to better understand everything from Pop to Postmodernism. Intimately wedded to the worlds of conceptual art and poetics, Radical Coherency collects Antin’s influential critical essays and spontaneous, performed lectures (or “talk pieces”) for the very first time, capturing one of the most distinctive perspectives in contemporary literature. The essays presented here range from the first serious assessment of Andy Warhol published in a major art journal, as well as Antin’s provocative take on Clement Greenberg’s theory of Modernism, to frontline interventions in present debates on poetics and fugitive pieces from the ’60s and ’70s that still sparkle today—and represent a gold mine for art historians of the period. From John Cage to Allan Kaprow, Mark Rothko to Ludwig Wittgenstein, Antin takes the reader on an idiosyncratic, personal journey through twentieth-century culture with his trademark antiformalist panache—one thatwill be welcomed by any fan of this consummate trailblazer.

Book excerpt: This feminist novel "is an examination of childhood experiences viewed through the consciousness of a rebellious young girl in a convent school. Its unorthodox, minimally punctuated, and nonchronological narrative established Wittig’s course as a writer... The novel... is a brilliant account of the making of a feminine subject, from childhood to adolescence." --www.britannica.com.

Advisory Group for Aerospace Research and Development. Fluid Dynamics Panel. Special Course and published by . This book was released on 1991 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report consists of lecture notes of an AGARD Fluid Dynamics Panel Special Course. These notes provide the latest information on the development and use of dynamic experiments in wind tunnels from several of the NATO nations. They address current oscillatory and rotary test techniques, experimental results for typical configurations, and the use of these data for flight mechanics applications. Subject included are: dynamic lift, wing rock, fluid dynamics of rotary flows, mathematical modelling, non-linear data representation, vortex manipulation for control enhancement, and correlations of predictions based on rotary and oscillatory wind-tunnel and flight-test results. The complete course notes are contained in two volumes. The main part of the notes is contained in AGARD Advisory Report 265 (ADA235179). The present volume includes papers on: Unsteady aerodynamics of slender wings; Dynamic stall effects and applications to high performance aircraft; Oscillatory test techniques; Large amplitude oscillations; Oscillatory data for typical configurations; and Forebody vortex control."--Stinet.
