This book was released on 1970 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Notre étude avait pour but la mise au point de techniques de mesure du transfert de chaleur entre un plasma et un solide dans quelques configurations particulières et l'élaboration de modèles mathématiques simples qui, en faisant intervenir les propriétés de transfert d'un plasma analogues à celles d'un fluide, permettent de calculer les flux de chaleur transférés dans chaque cas envisagés. Nous rappelerons ici les principaux résultats obtenus en dégageant leurs incertitudes pour proposer quelques prolongements à ce travail.

MAGNAVAL and published by . This book was released on 1999 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL OUVRE LE CHAMP EXPLORATOIRE DE L'ELABORATION DE COUCHES MINCES DE SILICIUM PAR DEPOT RAPIDE EN PLASMA THERMIQUE. L'OBJECTIF RECHERCHE EST L'OBTENTION D'UN MATERIAU DE HAUTE PURETE A PROPRIETE SEMICONDUCTRICE DANS LE CADRE DES APPLICATIONS PHOTOVOLTAIQUES. L'ETUDE EFFECTUEE EST CENTREE SUR LA MISE AU POINT D'UN PROCEDE DE FUSION DE PARTICULES DE SILICIUM DE DIAMETRES INITIALS VARIABLES (50 A 200 M) PAR TRANSFERT THERMIQUE ENTRE LE PLASMA ARGON/HYDROGENE ET LA PARTICULE. L'HYDRODYNAMIQUE DE L'ECOULEMENT, LES PROPRIETES DE TRANSPORT DU PLASMA, LES PROPRIETES PHYSIQUES DU MATERIAU CONSTITUENT LES PREMIERES ETAPES DU TRAVAIL A ANALYSER. IL CONVIENT EN PARTICULIER DE MESURER LE TEMPS DE SEJOUR DES PARTICULES DANS LES CHAMPS DE TEMPERATURES DU JET PLASMA ENGENDRE PAR LA TORCHE RF. CETTE ETUDE EXPERIMENTALE ASSOCIANT ANEMOMETRIE DOPPLER LASER, POUR LA MESURE DES VITESSES, ET EMISSION ATOMIQUE DES ESPECES DANS LE PLASMA, PERMET DE SUIVRE LES ECHANGES DE MATIERE SUR LA TRAJECTOIRE DES PARTICULES ET PAR LA MEME, PERMET DE REMONTER AUX ECHANGES DE CHALEUR RESPONSABLES DES PROCESSUS DE FUSION, D'EVAPORATION ET DE PURIFICATION DU MATERIAU. LA NATURE DU GAZ PLASMAGENE ET EN PARTICULIER LA TENEUR EN HYDROGENE DU MELANGE ARGON/HYDROGENE CONSTITUE UNE ETAPE IMPORTANTE PUISQU'ELLE AGIT SIMULTANEMENT SUR LES PHENOMENES DE TRANSFERT DE CHALEUR ET SUR LE PROCESSUS DE MODIFICATION CHIMIQUE DU MATERIAU (REDUCTION DES OXYDES, DIFFUSION DE L'HYDROGENE A CUR). LA QUALIFICATION DES COUCHES OBTENUES PAR MEB, XPS ET SPECROSCOPIE DE MASSE A PARTIR D'ECHANTILLONS TESTS PERMET DE RELIER LE PROCEDE DE FUSION ET L'ELABORATION D'UN MATERIAU COUCHE MINCE.

Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.
Download or read book Aeronomy written by P. M. Banks and published by Elsevier. This book was released on 2013-09-24 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeronomy, Part A is an attempt to make a comprehensive exposition of the processes in aeronomy, the study of composition, movement, and thermal balance of the upper regions of the planetary atmosphere. The text covers topics such as atmospheric regions and atmospheric density, the temperature and molecular mass of the atmosphere; the permanent constituents and the molecular and isotonic composition of the homosphere; and the transition from the homosphere to the heterosphere. Also covered are topics such as the temperature gradient and energies in the thermosphere, conditions at 200km and above 250km, solar radiation and ionization, and aeronomic reactions. The book is recommended for scientists, especially natural physicists, who would like to know more about the field of aeronomy and its advances.
Download or read book Genmix written by D Brian Spalding and published by Elsevier. This book was released on 2014-05-18 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genmix: A General Computer Program for Two-dimensional Parabolic Phenomena explains a computer program called GENMIX. The main intention of the program is to be used as a tool of instructions. The name of the program is a mixture of two considerations: its generality and its concern for mixing processes. The book aims to help the potential user to understand the physical and mathematical basis of the topic computer program. It is also the aim of the book to make the program applicable to practical problems. The book is arranged in such a way as to parallel a course of lectures and associated computer-workshop sessions wherein the student is allowed to do some elementary computations as soon as he has gained some knowledge of the method. The book contains the mathematical, physical, and computer-coding aspects of the program. Concepts such as the boundary layer, two-dimensional, and steady- flow are defined and discussed in depth. The text will be a useful tool for computer instructors and students.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, devenu célèbre sous son sigle MCSE, a déjà été utilisé par plus de 50 000 étudiants, chercheurs, professionnels. L'objectif est de lire et écrire des textes en anglais scientifique avec facilité et pertinence. L'ouvrage est conçu pour que l'apprenant devienne un véritable utilisateur de l'anglais. La méthode originale repose sur l'analyse des fonctions et structures nécessaires : measurement, frequency, comparison, modification, link words, time, cause and consequence, hypothesis, modality, purpose and process, impersonal forms, compound nouns and adjectives. Dans chaque unit, des tests d'auto-évaluation permettent de se situer et de construire son parcours de formation, d'abord en définissant ses objectifs à l'aide des key points et du lexis, puis, de façon plus personnalisée, en puisant dans les examples in context, checkpoints (back to basics, word web), web search, FAQs... MCSE est l'outil de base d'une méthode qui comprend aussi d'autres outils dans la même collection (Listening Comprehension for Scientiflc English et Speaking Skills in Scientitic English). L'ouvrage est destiné à tout apprenant de niveau baccalauréat qui désire acquérir une réelle compétence dans l'écriture et la lecture de textes en anglais scientifique.
