Book Synopsis Diversité Doppler et diversité de l'espace signal pour la transmission dans les canaux à évanouissements by : Richard Boudreau
Download or read book Diversité Doppler et diversité de l'espace signal pour la transmission dans les canaux à évanouissements written by Richard Boudreau and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La propagation dans les canaux de radiocommunications mobiles représente un défi considérable pour les concepteurs de systèmes de télécommunications. Les variations temporelles du canal engendrent des fluctuations de puissance du signal reçu qui peuvent s'étendre sur plusieurs dizaines de dB. Dans les cas extrêmes, le signal peut être atténué au point où sa puissance est en deçà du seuil de sensibilité du récepteur. Pour pallier à ce problème, on peut recourir à des techniques de diversité. Celles-ci visent à transmettre la même information sur plusieurs voies pour diminuer la probabilité de perte du signal au récepteur. Parmi ces techniques, deux, assez récentes, peuvent être considérées comme étant intrinsèques car elles exploitent, en quelque sorte, une forme du redondance contenue dans le signal. Ce sont la diversité Doppler et la diversité de l'espace signal. Elles font l'objet du présent travail. Les concepts de base sont expliqués, et on présente les résultats de simulations dans des canaux à évanouissements de Rayleigh et de Rice.
Book Synopsis Diversité spatiale et compensation Doppler en communication sous-marine sur signaux large-bandes by : Bastien Lyonnet
Download or read book Diversité spatiale et compensation Doppler en communication sous-marine sur signaux large-bandes written by Bastien Lyonnet and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le milieu sous-marin est doublement dispersif, en temps et en fréquence. 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.

Book Synopsis New Directions in Literature and Medicine Studies by : Stephanie M. Hilger
Download or read book New Directions in Literature and Medicine Studies written by Stephanie M. Hilger and published by Springer. This book was released on 2017-11-11 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is situated in the field of medical humanities, and the articles continue the dialogue between the disciplines of literature and medicine that was initiated in the 1970s and has continued with ebbs and flows since then. Recently, the need to renew that interdisciplinary dialogue between these two fields, which are both concerned with the human condition, has resurfaced in the face of institutional challenges, such as shrinking resources and the disappearance of many spaces devoted to the exchange of ideas between humanists and scientists. This volume presents cutting-edge research by scholars keen on not only maintaining but also enlivening that dialogue. They come from a variety of cultural, academic, and disciplinary backgrounds and their essays are organized in four thematic clusters: pedagogy, the mind-body connection, alterity, and medical practice.

Book Synopsis Mathematics, Education and History by : Kathleen M. Clark
Download or read book Mathematics, Education and History written by Kathleen M. Clark and published by Springer. This book was released on 2018-03-30 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes 18 peer-reviewed papers from nine countries, originally presented in a shorter form at TSG 25 The Role of History of Mathematics in Mathematics Education, as part of ICME-13 during. It also features an introductory chapter, by its co-editors, on the structure and main points of the book with an outline of recent developments in exploring the role of history and epistemology in mathematics education. It serves as a valuable contribution in this domain, by making reports on recent developments in this field available to the international educational community, with a special focus on relevant research results since 2000. The 18 chapters of the book are divided into five interrelated parts that underlie the central issues of research in this domain: 1. Theoretical and conceptual frameworks for integrating history and epistemology in mathematics in mathematics education; 2. Courses and didactical material: Design, implementation and evaluation; 3. Empirical investigations on implementing history and epistemology in mathematics education; 4. Original historical sources in teaching and learning of and about mathematics; 5. History and epistemology of mathematics: Interdisciplinary teaching and sociocultural aspects. This book covers all levels of education, from primary school to tertiary education, with a particular focus on teacher education. Additionally, each chapter refers to and/or is based on empirical research, in order to support, illuminate, clarify and evaluate key issues, main questions, and conjectured theses raised by the authors or in the literature on the basis of historical-epistemological or didactical-cognitive arguments.

Book Synopsis Introduction to Clinical Examination by : Michael J. Ford
Download or read book Introduction to Clinical Examination written by Michael J. Ford and published by Elsevier Health Sciences. This book was released on 2005-01-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important core skills for medical students to master are history taking and clinical examination. This extensively revised, eighth edition has been written with the philosophy that the acquisition of clinical skills is most effectively undertaken at the bedside. This pocketbook should be used as a companion, to be taken onto the wards and into consulting rooms where the information is most needed. The book begins with a system of history taking followed by a new chapter on the analysis of key symptoms. The remaining chapters cover physical examination of each of the major systems. Each stage of the examination starts with a detailed, step-by-step description of the examination method complemented by relevant illustrations, diagrams and tables on the facing page. This book is intended primarily for use at the outset of clinical training; once students have achieved proficiency in the basic skills of interviewing and examining, the book should also prove useful for revision. An invaluable starter book concentrating purely on the fundamentals of performing a patient examination. Covers each body system and outlines the principles of: - taking a history - how to conduct a physical examination - specific examination points as appropriate Concentrates only on the main symptoms of disease and then the normal and abnormal physical findings. Mention of specific diseases is confined to those most commonly encountered. Compact and pocket-sized to be carried around easily. · Now in full colour double-page format · Clear simple colour line drawings covering the essentials of a clinical examination. · Published simultaneously with the Eleventh Edition of Macleod's Clinical Examination
