Available in PDF, EPUB and Kindle. Book excerpt: Les signaux non-stationnaires qui font l'objet de la thèse sont d'abord envisagés d'un point de vue général et traités par une approche temps-fréquence ; on étudie ensuite des signaux non-stationnaires répétitifs en faisant intervenir la sommation synchrone. L'étude des signaux non-stationnaires par des représentations temps-fréquence permet le suivi de l'évolution spectrale du signal au cours du temps. Nous avons étudié et amélioré certaines méthodes appartenant à la classe de Cohen en les identifiant à des lissages de la transformée de Wigner-Ville et en étudiant leurs propriétés dans le plan fréquence-fréquence. Nous avons opposé à ces lissages linéaires, d'autres dont les paramètres varient soit en fonction du contenu spectral du signal en chaque point du plan temps-fréquence, soit en suivant une loi de variation définie à priori. La transformée en ondelette de Morlet, qui appartient à cette dernière classe, a été étudiée et une modification a été proposée. Le caractère répétitif de certains signaux d'application tels que les potentiels évoqués ou les signaux cardiaques, nous a amené à concevoir de nouvelles méthodes d'estimation de retards entre les réalisations du signal. La qualité des estimateurs proposés permet tout d'abord d'améliorer le signal moyen. De plus une estimation suffisamment précise de l'écart-type du jitter permet d'envisager un réhaussement du signal moyen par déconvolution. Une analyse temps-fréquence sur les signaux moyens permet alors de façon plus précise de déceler les détails permanents d'une réalisation à l'autre. L'amélioration des techniques de sommation synchrone rend possible, en réduisant le nombre de signaux sommés, de suivre des variations dynamiques réellement observées. Un algorithme adaptatif LMS a été proposé et son équivalence avec le moyennage à pondération exponentielle a été établie

Download or read book The History of Mathematical Proof in Ancient Traditions written by Karine Chemla and published by Cambridge University Press. This book was released on 2012-07-05 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This radical, profoundly scholarly book explores the purposes and nature of proof in a range of historical settings. It overturns the view that the first mathematical proofs were in Greek geometry and rested on the logical insights of Aristotle by showing how much of that view is an artefact of nineteenth-century historical scholarship. It documents the existence of proofs in ancient mathematical writings about numbers and shows that practitioners of mathematics in Mesopotamian, Chinese and Indian cultures knew how to prove the correctness of algorithms, which are much more prominent outside the limited range of surviving classical Greek texts that historians have taken as the paradigm of ancient mathematics. It opens the way to providing the first comprehensive, textually based history of proof.
Download or read book Nature and Society written by Philippe Descola and published by Routledge. This book was released on 2003-12-16 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributors to this book focus on the relationship between nature and society from a variety of theoretical and ethnographic perspectives. Their work draws upon recent developments in social theory, biology, ethnobiology, epistemology, sociology of science, and a wide array of ethnographic case studies -- from Amazonia, the Solomon Islands, Malaysia, the Mollucan Islands, rural comunities from Japan and north-west Europe, urban Greece, and laboratories of molecular biology and high-energy physics. The discussion is divided into three parts, emphasising the problems posed by the nature-culture dualism, some misguided attempts to respond to these problems, and potential avenues out of the current dilemmas of ecological discourse.
Download or read book The Comparative Embryology of Sponges written by Alexander V. Ereskovsky and published by Springer Science & Business Media. This book was released on 2010-03-27 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

Download or read book Local Approximation Techniques in Signal and Image Processing written by Vladimir I︠A︡kovlevich Katkovnik and published by SPIE-International Society for Optical Engineering. This book was released on 2006 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a wide class of novel and efficient adaptive signal processing techniques developed to restore signals from noisy and degraded observations. These signals include those acquired from still or video cameras, electron microscopes, radar, X-rays, or ultrasound devices, and are used for various purposes, including entertainment, medical, business, industrial, military, civil, security, and scientific. In many cases useful information and high quality must be extracted from the imaging. However, often raw signals are not directly suitable for this purpose and must be processed in some way. Such processing is called signal reconstruction. This book is devoted to a recent and original approach to signal reconstruction based on combining two independent ideas: local polynomial approximation and the intersection of confidence interval rule.

Download or read book Gender Biased Sex Selection in South Korea India and Vietnam written by Laura Rahm and published by Springer. This book was released on 2019-07-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth analysis of the influence of public policy on sex selection. Three Asian countries were chosen for the comparative policy analysis, namely South Korea, India and Vietnam that share in common a historical legacy of son preference, high levels of sex imbalances and active policy response to curbing the growing demographic masculinization of their nations. The research based on the data collected from field work in the three countries shows that despite the adoption of very similar anti-sex selection policies the outcomes have been markedly different for each of the three countries. These unexpected diverse outcomes are explained partly by their different historical and cultural contexts, and partly to the different social, political and economic institutions and dynamics. This monograph offers careful and detailed explanations of both within and across country diversities in policy outcomes, pointing to the importance and the limits of cross-national policy learning and adoption, and raising questions about the efficacy of international organizations’ current approaches to global policy and knowledge transfer.
