Differential geometry applied to dynamical systems by Jean-Marc Ginoux( Book )

19 editions published between 2008 and 2009 in English and held by 109 WorldCat member libraries worldwide

This book aims to present a new approach called Flow Curvature Method that applies Differential Geometry to Dynamical Systems. Hence, for a trajectory curve, an integral of any n-dimensional dynamical system as a curve in Euclidean n-space, the curvature of the trajectory - or the flow - may be analytically computed. Then, the location of the points where the curvature of the flow vanishes defines a manifold called flow curvature manifold. Such a manifold being defined from the time derivatives of the velocity vector field, contains information about the dynamics of the system, hence identifying the main features of the system such as fixed points and their stability, local bifurcations of codimension one, center manifold equation, normal forms, linear invariant manifolds (straight lines, planes, hyperplanes). In the case of singularly perturbed systems or slow-fast dynamical systems, the flow curvature manifold directly provides the slow invariant manifold analytical equation associated with such systems. Also, starting from the flow curvature manifold, it will be demonstrated how to find again the corresponding dynamical system, thus solving the inverse problem
Henri Poincaré : a biography through the daily papers by Jean-Marc Ginoux( Book )

14 editions published between 2013 and 2014 in English and Undetermined and held by 94 WorldCat member libraries worldwide

On July 17, 2012, the centenary of Henri Poincaré's death was commemorated; his name being associated with so many fields of knowledge that he was considered as the last universalist. In pure and applied mathematics, physics, astronomy, engineering and philosophy, his works have had a great impact all over the world. Poincaré acquired in his lifetime such a reputation that, both nationally and internationally, his life and career were made the object of various articles in the daily papers not only in France, but also in the USA. Some of his philosophical concepts have even caused sharp controversies in the press (as we will discover in this book). This work presents an original portrait of Henri Poincaré based on various unknown anecdotes of his life (for example, his first name was actually not Henri, but Henry; he obtained his high school diploma in sciences with a zero in mathematics, etc.) and from what was reported by the newspapers of his time

Albert Einstein : une biographie à travers le temps by Jean-Marc Ginoux( Book )

2 editions published in 2016 in French and held by 20 WorldCat member libraries worldwide

"Cette biographie présente un portrait inédit du célèbre physicien Albert Einstein entièrement réalisé à partir de coupures de presse d'un grand quotidien new-yorkais, le New York Times. Le nombre impressionnant d'articles rédigés sur sa vie et sur son oeuvre offre une approche originale du personnage. Il permet de reconstituer, presque au jour le jour, les évènements les plus marquants de sa vie et de mettre en lumière certains de ses traits de caractère les plus intimes qui apparaissent dans les interviews qu'il accorda à ce quotidien. Cet ouvrage grand public, dénué de tout développement mathématique, fournit également une présentation de ses théories scientifiques (théorie de la relativité restreinte et générale, théorie du champ unifié) qui deviennent accessibles à tous. Au fil des articles, le lecteur découvre un Einstein inattendu grâce à des anecdotes drôles et insolites." (source : 4ème de couverture)
History of nonlinear oscillations theory in France (1880-1940) by Jean-Marc Ginoux( Book )

3 editions published in 2017 in English and held by 8 WorldCat member libraries worldwide

This book reveals the French scientific contribution to the mathematical theory of nonlinear oscillations and its development. The work offers a critical examination of sources with a focus on the twentieth century, especially the period between the wars. Readers will see that, contrary to what is often written, France's role has been significant. Important contributions were made through both the work of French scholars from within diverse disciplines (mathematicians, physicists, engineers), and through the geographical crossroads that France provided to scientific communication at the time. This study includes an examination of the period before the First World War which is vital to understanding the work of the later period. By examining literature sources such as periodicals on the topic of electricity from that era, the author has unearthed a very important text by Henri Poincaré, dating from 1908. In this work Poincaré applied the concept of limit cycle (which he had introduced in 1882 through his own works) to study the stability of the oscillations of a device for radio engineering. The “discovery” of this text means that the classical perspective of the historiography of this mathematical theory must be modified. Credit was hitherto attributed to the Russian mathematician Andronov, from correspondence dating to 1929. In the newly discovered Poincaré text there appears to be a strong interaction between science and technology or, more precisely, between mathematical analysis and radio engineering. This feature is one of the main components of the process of developing the theory of nonlinear oscillations. Indeed it is a feature of many of the texts referred to in these chapters, as they trace the significant developments to which France contributed. Scholars in the fields of the history of mathematics and the history of science, and anyone with an interest in the philosophical underpinnings of science will find this a particularly engaging account of scientific discovery and scholarly communication from an era full of exciting developments

Stabilité des systèmes dynamiques chaotiques et variétés singulières by Jean-Marc Ginoux( Book )

2 editions published in 2005 in French and held by 2 WorldCat member libraries worldwide

This work aims to study the stability of chaotic dynamical systems starting from the geometrical structure of their attractors of which a part is based on a manifold called slow manifold. To this end, a new approach based on certain aspects of the formalism of Mechanics and Differential Geometry was developed and led to a geometrical and kinematics interpretation of the evolution of the trajectory curves, integrals of these dynamical systems in the vicinity of the slow manifold, and allowed to study their stability. Mechanics allowed, with the use of the velocity and instantaneous acceleration vectors, located on a point of the trajectory curve, to discriminate the slow domain from the fast domain and to locate the position of the slow manifold inside the phase space. Certain notions of Differential Geometry like the expressions of curvature, torsion and that of the osculating plane provided an analytical equation of the slow manifold independent of the slow eigenvectors of the tangent linear system, therefore defined on a greater domain of the phase space. The slow manifold was then considered as the location of the points where the curvature of the trajectory curves, integrals of these dynamical systems, is minimal (in dimension two this minimum becomes equal to zero). The sign of torsion allowed: to characterize its attractivity, to discriminate the attractive part from the repulsive part of the slow manifold and, to rule on the stability of these trajectory curves. Thus, the presence in the phase space of an attractive slow manifold compelling the trajectory curve, integrals of the dynamic system to visit its vicinity allowed analyzing the attractor structure. This approach based on certain aspects of the formalism of Mechanics and Differential Geometry and which was accompanied by the development of numerical programs made it possible to constitute a new tool for investigation of chaotic dynamical systems. Its application to models of reference like that of B. Van der Pol., L.O. Chua or of E.N. Lorenz allowed obtaining more directly and with precision the analytical equation of their slow manifold. Moreover, a detailed study of the predator-prey models like that of Rosenzweig-MacArthur or Hastings-Powell, led on the one hand to the determination of their slow manifold and on the other hand to the design of a new three-dimensional model of predator-prey type: theVolterra-Gause model of which chaotic attractor has the shape of a snailshell (chaotic snail shell)

Combination of Wireless sensor network and artifical neuronal network : a new approach of modeling by Yi Zhao( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Face à la limitation de la modélisation paramétrique, nous avons proposé dans cette thèse une procédure standard pour combiner les données reçues a partir de Réseaux de capteurs sans fils (WSN) pour modéliser a l'aide de Réseaux de Neurones Artificiels (ANN). Des expériences sur la modélisation thermique ont permis de démontrer que la combinaison de WSN et d'ANN est capable de produire des modèles thermiques précis. Une nouvelle méthode de formation "Multi-Pattern Cross Training" (MPCT) a également été introduite dans ce travail. Cette méthode permet de fusionner les informations provenant de différentes sources de données d'entraînements indépendants (patterns) en un seul modèle ANN. D'autres expériences ont montré que les modèles formés par la méthode MPCT fournissent une meilleure performance de généralisation et que les erreurs de prévision sont réduites. De plus, le modèle de réseau neuronal basé sur la méthode MPCT a montré des avantages importants dans le multi-variable Model Prédictive Control (MPC). Les simulations numériques indiquent que le MPC basé sur le MPCT a surpassé le MPC multi-modèles au niveau de l'efficacité du contrôle
Ecologie des communautés zooplanctoniques au sein de deux écosystèmes littoraux méditerranéens : traitement des séries temporelles by Benjamim Bandeira( )

1 edition published in 2013 in French and held by 1 WorldCat member library worldwide

This work focused the study of the evolution of zooplankton communities from time series of surveys conducted from 1995 to 2010 in two coastal coupled ecosystems, Little Bay (PR) and Large Bay (GR) of Toulon (North Western Mediterranean Sea, France) in relation to climatic factors, physical and chemical water parameters and phytoplankton. The samplings surveys of zooplankton, and indeed also of phytoplankton, were a month, on average. The net mesh size used was 90 µm to target Mesozooplankton. The PR differed from the GR in its ecological functioning, because it is semi-closed, but also because human activity is much more important. Our results showed that, from 1995 to 2010 in both bays, zooplankton abundance increased substantially, especially in the PR. It was also established, using statistical tools, that most zooplankton species evolved coordinated each year, but in a different way from one year to another. This is what we call the annual signature, which was more pronounced in the PR. Several environmental parameters such as temperature, oxygen, salinity and sunlight, which were simultaneously recorded, explained this annual signature. It was shown that they significantly influenced the population of zooplankton, instantly or with a delayed effect. Interactions responsible for this development are complex, but it was also established that these factors were stronger when they acted in a coordinated manner. Distribution of zooplankton taxonomic groups showed diversity increases until 2005 and then decreased slightly, while remaining at levels higher than in 1995. The detailed study of diversity, with a classification of the clues themselves was the subject of the last chapter. Finally, we hypothesize that the decline of fish stocks in recent decades throughout the region, resulting in lower rate of predation on zooplankton communities, may explain the increase of zooplankton communities in recent years. This increase in zooplankton abundance could in turn lead to a decrease in phytoplankton biomass. The decrease of phytoplankton was at the same time observed by our team. The latter hypothesis suggests a top-down control of the the food web
