Book excerpt: CETTE THESE A POUR BUT LA MISE AU POINT ET LA VALIDATION D'UN CODE ADAPTE AUX HELICES RAPIDES APPELE BRHAVA. CELUI-CI INTEGRE LES ASPECTS AERODYNAMIQUES INSTATIONNAIRES NECESSAIRES A LA PREVISION DU BRUIT D'UNE HELICE EN INCIDENCE. LES TECHNIQUES ACTUELLES UTILISEES POUR MODELISER LE BRUIT D'UNE HELICE EN INCIDENCE REPOSENT POUR BON NOMBRE SUR LA FORMULATION ANALOGIQUE DE FFOWCS WILLIAMS ET HAWKINGS. CETTE ETUDE A ETE ORIENTEE VERS L'APPROCHE NUMERIQUE DE F. FARASSAT DANS LE DOMAINE TEMPOREL POUR LE CALCUL DU BRUIT D'EPAISSEUR ET DU BRUIT DE CHARGE, COMPOSANTES PRINCIPALES DU BRUIT DE RAIES EN REGIME SUBSONIQUE. PARMI LES FORMULATIONS SUCCESSIVES DE FARASSAT, LES PLUS RECENTES, (FORMULATION 1A ET FORMULATION 3) SONT EGALEMENT LES MIEUX ADAPTEES AUX HELICES AVANCEES. PAR AILLEURS LEUR MISE EN UVRE POUR UN MOUVEMENT TEL QUE CELUI D'UNE HELICE EN INCIDENCE EST PARTICULIEREMENT AISEE. UN BREF RAPPEL DES NOTIONS DE BASE DE L'AERODYNAMIQUE INSTATIONNAIRE DES HELICES PERMET DE RENDRE COMPTE DES EXIGENCES D'UN CALCUL ACOUSTIQUE. DES MESURES EN SOUFFLERIE REALISEES DANS LE CADRE DU PROGRAMME EUROPEEN SNAAP ONT ETE UTILISEES POUR LA VALIDATION DU LOGICIEL DE CALCUL BRHAVA. IL A ETE DECIDE D'UTILISER DES DONNEES AERODYNAMIQUES STATIONNAIRES CALCULEES SANS ANGLE D'INCIDENCE, COUPLEES AVEC DES DONNEES DE FLUCTUATIONS DE PRESSION SUR PALES MESUREES. DE TRES BONS RESULTATS ONT ETE OBTENUS POUR LA PLUPART DES CAS SANS INCIDENCE. POUR LES CAS AVEC INCIDENCE, DES MODIFICATIONS IMPORTANTES DANS LA DIRECTIVITE SONT ATTRIBUEES AUX SEULS EFFETS CINEMATIQUES. CEPENDANT ILS NE SUFFISENT PAS A EVALUER CORRECTEMENT LES NIVEAUX DE BRUIT. LA COMPARAISON DES CALCULS AVEC CHARGES INSTATIONNAIRES EST NETTEMENT MEILLEURE ET DEMONTRE QUE LA QUALITE DES PREVISIONS ACOUSTIQUES EST INTRINSEQUEMENT LIEE A CELLE DES DONNEES D'AERODYNAMIQUE INSTATIONNAIRE, CE QUI JUSTIFIE LES EFFORTS FUTURS A CONSENTIR DANS LEUR MODELISATION THEORIQUE.

Available in PDF, EPUB and Kindle. Book excerpt: Those Who from Afar Look Like Flies is an anthology of poems and essays that aims to provide an organic profile of the evolution of Italian poetry after World War II. Beginning with the birth of Officina and Il Verri, and culminating with the crisis of the mid-seventies, this tome features works by such poets as Pasolini, Pagliarani, Rosselli, Sanguineti and Zanzotto, as well as such forerunners as Villa and Cacciatore. Each section of this anthology, organized chronologically, is preceded by an introductory note and documents every stylistic or substantial change in the poetics of a group or individual. For each poet, critic, and translator a short biography and bibliography is also provided.

Download or read book MUSICAGE written by John Cage and published by Wesleyan University Press. This book was released on 2015-01-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pioneering composer and music theorist makes his final on the totality of his work and thought in these three wide-ranging dialogues. “I was obliged to find a radical way to work ― to get at the real, at the root of the matter,” John Cage says in this trio of dialogues, completed just days before his death. This quest led him beyond the bounds of convention in all his musical, written, and visual pieces. The resulting expansion of the definition of art earned him a reputation as one of America's most influential contemporary artists. Joan Retallack's conversations with Cage explore his artistic production in its entirety. Cage's comments range from his theories of chance and indeterminate composition to his long-time collaboration with Merce Cunningham to the aesthetics of his multimedia works. In her comprehensive introduction, Retallack describes Cage’s lifelong project as “dislodging cultural authoritarianism and gridlock by inviting surprising conjunctions within carefully delimited frameworks and processes.” Consummate performer to the end, Cage delivers here just such a conjunction ― a tour de force that provides new insights into the man and a clearer view of the status of art in the twentieth century.
Book Synopsis The Analysis and Cognition of Melodic Complexity by : Eugene Narmour
Download or read book The Analysis and Cognition of Melodic Complexity written by Eugene Narmour and published by University of Chicago Press. This book was released on 1992-11 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, Eugene Narmour extends the unique theories of musical perception presented in The Analysis and Cognition of Basic Melodic Structures. The two books together constitute the first comprehensive theory of melody founded on psychological research. Narmour's earlier study dealt with cognitive relations between melodic tones at their most basic level. After summarizing the formalized methodology of the theory described in that work, Narmour develops an elaborate and original symbology to show how sixteen archetypes can combine to form some 200 complex structures that, in turn, can chain together in a theoretically infinite number of ways. He then explains and speculates on the cognitive operations by which listeners assimilate and ultimately encode these complex melodic structures. More than 250 musical examples from different historical periods and non-Western cultures demonstrate the panstylistic scope of Narmour's model. Of particular importance to music theorists and music historians is Narmour's argument that melodic analysis and formal analysis, though often treated separately, are in fact indissolubly linked. The Analysis and Cognition of Melodic Complexity will also appeal to ethnomusicologists, psychologists, and cognitive scientists.
Book Synopsis Transonic Aerodynamics by : L. Pamela Cook
Download or read book Transonic Aerodynamics written by L. Pamela Cook and published by SIAM. This book was released on 1993-01-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers exciting results, perspectives, and case studies for the treatment of problems arising in transonic aerodynamics. New advances including triple deck theory, analysis of stagnation at the nose of a body, transonic choked flow, and the transonic area rule are presented. Interest in analyzing the transonic range of flight, its stability properties, and especially the question of designing reduced drag (shockless or weak shock) airfoils keeps growing. Present day commercial aircraft cruise in the transonic range. Mechanical and aeronautical engineers interested in compressible fluid flows, design of optimal wings, and an understanding of transonic flow held about wings and airfoils will find the book invaluable. This book is understandable to those with a knowledge of continuum mechanics (fluids) and asymptotic methods. It is appropriate for graduate courses in aerodynamics and mathematical methods.
Book Synopsis The Analysis and Cognition of Basic Melodic Structures by : Eugene Narmour
Download or read book The Analysis and Cognition of Basic Melodic Structures written by Eugene Narmour and published by . This book was released on 1990-01 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eugene Narmour formulates a comprehensive theory of melodic syntax to explain cognitive relations between melodic tones at their most basic level. Expanding on the theories of Leonard B. Meyer, the author develops one parsimonious, scaled set of rules modeling implication and realization in all the primary parameters of music. Through an elaborate and original analytic symbology, he shows that a kind of "genetic code" governs the perception and cognition of melody. One is an automatic, "brute" system operating on stylistic primitives from the bottom up. The other constitutes a learned system of schemata impinging on style structures from the top down. The theoretical constants Narmour uses are context-free and, therefore, applicable to all styles of melody. He places considerable emphasis on the listener's cognitive performance (that is, fundamental melodic perception as opposed to acquired musical competence). He concentrates almost exclusively on low-level, note-to-note relations. The result is a highly generalized theory useful in researching all manner of psychological and music-theoretic problems concerned with the analysis and cognition of melody. "In this innovative, landmark book, a distinguished music theorist draws extensively from a variety of disciplines, in particular from cognitive psychology and music theory, to develop an elegant and persuasive framework for the understanding of melody. This book should be read by all scholars with a serious interest in music."—Diana Deutsch, Editor, Music Perception
