L'utilisation récente de signaux de communication multi-porteuses offre une solution pour lutter contre la sélectivité fréquentielle. Mais ce type de signaux reste très sensible à la dispersivité fréquentielle. Cette thèse se concentre sur le problème de la dispersivité fréquentielle qu'est l'effet Doppler. Des méthodes d'estimation du paramètre Doppler sont développées pour des signaux multi-porteuses DMT. Est également abordé le problème de la compensation Doppler dans les cas mono et multitrajets. Une méthode générale et une méthode spéci que au signaux multiporteuses sont présentées et testées sur simulation. Cette thèse se distingue par son modèle du canal sous-marin qui considère un paramètre Doppler différent sur chaque trajet. Ceci résulte de la géométrie du problème et des vitesses émetteur/récepteur considérées. Nous présentons nalement des méthodes pour séparer les différents trajets arrivant sur une antenne a n de pouvoir considérer un paramètre Doppler unique sur chacun.

Available in PDF, EPUB and Kindle. Book excerpt: Biosocialities, Genetics and the Social Sciences explores the social, cultural and economic transformations that result from innovations in genomic knowledge and technology. This pioneering collection uses Paul Rabinow’s concept of biosociality to chart the shifts in social relations and ideas about nature, biology and identity brought about by developments in biomedicine. Based on new empirical research, it contains chapters on genomic research into embryonic stem cell therapy, breast cancer, autism, Parkinson’s and IVF treatment, as well as on the expectations and education surrounding genomic research. It covers four main themes: novel modes of identity and identification, such as genetic citizenship the role of institutions, ranging from disease advocacy organizations and voluntary organizations to the state the production of biological knowledge, novel life-forms, and technologies the generation of wealth and commercial interests in biology. Including an afterword by Paul Rabinow and case studies on the UK, US, Canada, Germany, India and Israel, this book is key reading for students and researchers of the new genetics and the social sciences – particularly medical sociologists, medical anthropologists and those involved with science and technology studies.

Available in PDF, EPUB and Kindle. Book excerpt: The Cahiers/Notebooks of Paul Valéry are a unique form of writing. They reveal Valéry as one of the most radical and creative minds of the twentieth century, encompassing a wide range of investigation into all spheres of human activity. His work explores the arts, the sciences, philosophy, history and politics, investigating linguistic, psychological and social issues, all linked to the central questions, relentlessly posed: 'what is the human mind and how does it work?', 'what is the potential of thought and what are its limits?' But we encounter here too, Valéry the writer: exploratory, fragmentary texts undermine the boundaries between analysis and creativity, between theory and practice. Neither journal nor diary, eluding the traditional genres of writing, the Notebooks offer lyrical passages, writing of extreme beauty, prose poems of extraordinary descriptive power alongside theoretical considerations of poetics, ironic aphorisms and the most abstract kind of analysis. The concerns and the insights that occupied Valéry's inner voyages over more than 50 years remain as relevant as ever for the contemporary reader: for the Self that is his principal subject is at once singular and universal.

Book Synopsis An Introduction to Differential Manifolds by : Jacques Lafontaine

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.

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.
