Book Synopsis Inversion de données électromagnétiques par algorithme génétique pour la télédétection en zone forestière by : Mahmoud Kanj

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La problématique de l'imagerie radar pose comme objectif de caractériser la cible observée. Dans le contexte de la télédétection appliquée aux milieux forestiers, il s'agit d'extraire les paramètres physiques constitutifs de la végétation.Ce manuscrit traite donc de la problématique de l'inversion de données électromagnétiques pour les basses fréquences radar, de la bande VHF à la bande P. Dans ces bandes de fréquences la canopée (feuilles et petites branches) n'interagit quasiment pas avec l'onde radar et la forêt peut donc, en première approximation, être représentée par des cylindres verticaux (troncs) et inclinés (branches primaires).Dans ce contexte, les méthodes d'inversion numériques s'appuient sur des modèles qui calculent, à de multiples reprises, les champs rayonnés par ce type de diffuseurs. Il faut alors choisir un modèle physique dont le compromis rapidité/précision penche en faveur de la rapidité, donc un modèle "approché". La précision du modèle choisi est ensuite étudié puis validé par comparaison à un modèle dont le compromis rapidité/précision est inversé, donc un modèle "exact". Parmi les nombreuses méthodes d'inversion, celle de l'algorithme génétique (AG) a été choisie. Cet algorithme bien connu est ici analysé puis amélioré pour répondre aux exigences du problème électromagnétique posé. Il est ensuite validé sur des données simulées et mesurées. Cette validation est aussi l'occasion d'étudier l'impact du jeu de données utilisé sur la rapidité et la précision de l'inversion, en fonction des configurations d'antenne (fréquences, positions, polarisations).

Book Synopsis On-line Estimation and Adaptive Control of Bioreactors by : G. Bastin
Download or read book On-line Estimation and Adaptive Control of Bioreactors written by G. Bastin and published by Elsevier. This book was released on 2013-10-22 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with monitoring and control of biotechnological processes. Different methods are proposed which are based on the nonlinear structure of the process and do not require any a priori knowledge of the fermentation parameters. The theoretical stability and convergence properties of the proposed algorithms are analysed and their performances are illustrated by simulation results and, in many instances, by real life experiments. The concept of software sensors is introduced; these are algorithms based on the nonlinear model of the process and designed for on-line estimation of the biological variables and/or the fermentation parameters. In order to deal with process nonstationarities and parameter uncertainties, reference is made to adaptive estimation and control techniques.The book is the result of an intensive joint research effort by the authors during the last decade. It is intended as a graduate level text for students of bioengineering as well as a reference text for scientists and engineers involved in the design and optimization of bioprocesses.
Book Synopsis Semigroups for Delay Equations by : András Bátkai
Download or read book Semigroups for Delay Equations written by András Bátkai and published by A K Peters, Ltd.. This book was released on 2005 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most physical, chemical, biological and economic phenomena it is quite natural to assume that the system not only depends on the present state but also on past occurrences. These circumstances are mathematically described by partial differential equations with delay. This book presents, in a systematic fashion, how delay equations can be studied in Lp-history spaces.Appendices offering supplementary information and a comprehensive index make this book an ideal introduction and research tool for mathematicians, chemists, biologists and economists.

Book Synopsis Geometric Control Theory by : Velimir Jurdjevic
Download or read book Geometric Control Theory written by Velimir Jurdjevic and published by Cambridge University Press. This book was released on 1997 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geometric control theory is concerned with the evolution of systems subject to physical laws but having some degree of freedom through which motion is to be controlled. This book describes the mathematical theory inspired by the irreversible nature of time evolving events. The first part of the book deals with the issue of being able to steer the system from any point of departure to any desired destination. The second part deals with optimal control, the question of finding the best possible course. An overlap with mathematical physics is demonstrated by the Maximum principle, a fundamental principle of optimality arising from geometric control, which is applied to time-evolving systems governed by physics as well as to man-made systems governed by controls. Applications are drawn from geometry, mechanics, and control of dynamical systems. The geometric language in which the results are expressed allows clear visual interpretations and makes the book accessible to physicists and engineers as well as to mathematicians.
Book Synopsis Positive 1D and 2D Systems by : Tadeusz Kaczorek
Download or read book Positive 1D and 2D Systems written by Tadeusz Kaczorek and published by Springer Science & Business Media. This book was released on 2002 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is devoted to the positive multivariable 1D and 2D linear, time-invariant, finite-dimensional system. The book is based on the author's lectures for Ph.D. students, delivered at Warsaw University of Technology in the academic year 1999/2000. The book consists of two parts; the first part is devoted to the 1D positive linear systems and the second to the 2D positive linear systems described by the Rosser model and the Fornasini-Marchesini models. Definitions, basic properties and theorems concerning positive matrices and graphs are presented; the externally and internally positive linear continuous-time and discrete-time linear systems are considered; and the reachability, controlability and observability of positive linear systems are discussed. The realisation problem for positive 1D and 2D systems is also considered, and the 2D models of externally and internally positive and their properties and controllability and minimum energy control of positive 2D systems are investigated.

Book Synopsis Virtual Geographic Environments by : Hui Lin
Download or read book Virtual Geographic Environments written by Hui Lin and published by ESRI Press. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual Geographic Environments, edited by Hui Lin and Michael Batty, collects key papers that define the current momentum in GIS and "virtual geographies." Contributions by leading members of the geospatial community to Virtual Geographic Environments illustrate the cutting edge of GIScience, as well as new applications of GIS with the processing and delivery of geographic information through the Web and handheld devices, forming two major directions to these developments. The four-part organization leads from a primer on VGEs to virtual cities and landscapes, interface design and public participation, and finally mobile and networked VGEs. Current topics, such as crowd sourcing and related services, point to the development of new business models that merge proprietary and nonproprietary systems.
