Book excerpt: LES ETUDES SUR LES JETS PARIETAUX PEUVENT ETRE CLASSES EN GROS, EN DEUX GROUPES. L'UN CONCERNANT CELLES RELATIVES A L'ETUDE CINEMATIQUE DE L'ECOULEMENT DANS LA ZONE DITE DE REGIME ETABLI, ET LE SECOND CONCERNE CELLES RELATIVES AUX ASPECTS THERMIQUES DU PROBLEME. LE PRESENT TRAVAIL S'INSCRIT AU SEIN DU PREMIER GROUPE D'ETUDES. IL PRESENTE DE MULTIPLES ASPECTS RELATIFS AU JET PARIETAL ET QUI INTERFERENT LES UNS AVEC LES AUTRES. DANS UNE ETUDE BIBLIOGRAPHIQUE APPROFONDIE DU JET PARIETAL (CHAPITRE 1), NOUS AVONS PRESENTE UN ENSEMBLE DE DONNEES THEORIQUES ET EXPERIMENTALES PROVENANT DE LA LITTERATURE. LES RESULTATS PROVENANT DES THEORIES ET SURTOUT LES FORMULES SEMI-EMPIRIQUES SONT COMPAREES LES UNES AUX AUTRES AINSI QU'AUX EXPERIENCES. LA SECONDE PARTIE (CHAPITRE 2) CONSISTE EN UNE ETUDE THEORIQUE D'UN JET PARIETAL, PLAN LAMINAIRE ET A BASSES VITESSES, DELIVRE PAR UNE SOUFFLERIE SUBSONIQUE.

Book excerpt: Loss of Signal, a NASA publication to be available in May 2014, presents the aeromedical lessons learned from the Columbia accident that will enhance crew safety and survival on human space flight missions. These lessons were presented to limited audiences at three separate Aerospace Medical Association (AsMA) conferences: in 2004 in Anchorage, Alaska, on the causes of the accident; in 2005 in Kansas City, Missouri, on the response, recovery, and identification aspects of the investigation; and in 2011, again in Anchorage, Alaska, on future implications for human space flight. As we embark on the development of new spacefaring vehicles through both government and commercial efforts, the NASA Johnson Space Center Human Health and Performance Directorate is continuing to make this information available to a wider audience engaged in the design and development of future space vehicles. Loss of Signal summarizes and consolidates the aeromedical impacts of the Columbia mishap process-the response, recovery, identification, investigative studies, medical and legal forensic analysis, and future preparation that are needed to respond to spacecraft mishaps. The goals of this book are to provide an account of the aeromedical aspects of the Columbia accident and the investigation that followed, and to encourage aerospace medical specialists to continue to capture information, learn from it, and improve procedures and spacecraft designs for the safety of future crews.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers classical and modern aerodynamics, theories and related numerical methods, for senior and first-year graduate engineering students, including: -The classical potential (incompressible) flow theories for low speed aerodynamics of thin airfoils and high and low aspect ratio wings. - The linearized theories for compressible subsonic and supersonic aerodynamics. - The nonlinear transonic small disturbance potential flow theory, including supercritical wing sections, the extended transonic area rule with lift effect, transonic lifting line and swept or oblique wings to minimize wave drag. Unsteady flow is also briefly discussed. Numerical simulations based on relaxation mixed-finite difference methods are presented and explained. - Boundary layer theory for all Mach number regimes and viscous/inviscid interaction procedures used in practical aerodynamics calculations. There are also four chapters covering special topics, including wind turbines and propellers, airplane design, flow analogies and hypersonic (rotational) flows. A unique feature of the book is its ten self-tests and their solutions as well as an appendix on special techniques of functions of complex variables, method of characteristics and conservation laws and shock waves. The book is the culmination of two courses taught every year by the two authors for the last two decades to seniors and first-year graduate students of aerospace engineering at UC Davis.

Download or read book PanVascular Medicine written by Peter Lanzer and published by Springer. This book was released on 2015-03-30 with total page 5004 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​Vascular management and care has become a truly multidisciplinary enterprise as the number of specialists involved in the treatment of patients with vascular diseases has steadily increased. While in the past, treatments were delivered by individual specialists, in the twenty-first century a team approach is without doubt the most effective strategy. In order to promote professional excellence in this dynamic and rapidly evolving field, a shared knowledge base and interdisciplinary standards need to be established. Pan Vascular Medicine, 2nd edition has been designed to offer such an interdisciplinary platform, providing vascular specialists with state-of-the art descriptive and procedural knowledge. Basic science, diagnostics, and therapy are all comprehensively covered. In a series of succinct, clearly written chapters, renowned specialists introduce and comment on the current international guidelines and present up-to-date reviews of all aspects of vascular care.

Download or read book Biomechanics written by Y.C. Fung and published by Springer Science & Business Media. This book was released on 2013-03-20 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomechanics aims to explain the mechanics oflife and living. From molecules to organisms, everything must obey the laws of mechanics. Clarification of mechanics clarifies many things. Biomechanics helps us to appreciate life. It sensitizes us to observe nature. It is a tool for design and invention of devices to improve the quality of life. It is a useful tool, a simple tool, a valuable tool, an unavoidable tool. It is a necessary part of biology and engineering. The method of biomechanics is the method of engineering, which consists of observation, experimentation, theorization, validation, and application. To understand any object, we must know its geometry and materials of construc tion, the mechanical properties of the materials involved, the governing natural laws, the mathematical formulation of specific problems and their solutions, and the results of validation. Once understood, one goes on to develop applications. In my plan to present an outline of biomechanics, I followed the engineering approach and used three volumes. In the first volume, Biomechanics: Mechanical Properties of Living Tissues, the geometrical struc ture and the rheological properties of various materials, tissues, and organs are presented. In the second volume, Biodynamics: Circulation, the physiology of blood circulation is analyzed by the engineering method.
