Book Synopsis Inversion et assimilation de données de télédétection by : Yajing Yan
Download or read book Inversion et assimilation de données de télédétection written by Yajing Yan and published by ISTE Group. This book was released on 2023-03-01 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les données de télédétection constituent désormais les sources primordiales pour l’observation de la Terre et de l’Univers. Les techniques d’inversion et d’assimilation de données représentent les outils principaux permettant l’estimation et la prédiction des paramètres géophysiques qui caractérisent l’évolution de notre planète et de l’Univers, en exploitant les données de télédétection. Inversion et assimilation de données de télédétection traite des avancées récentes dans l’inversion et l’assimilation de données de télédétection. Il présente les méthodes traditionnelles et les méthodes actuelles de réseaux de neurones, ainsi que de nombreuses thématiques où ces méthodes ont été développées ou adaptées en fonction de la spécificité du domaine. La partie assimilation porte sur les problèmes de prédiction en surveillance de surface continentale, en modélisation des incendies de forêt, en volcanologie et en glaciologie. La partie inversion comprend l’inversion de la biomasse avec des images SAR, l’inversion bio-physio-hydrologique dans les zones côtières avec des images multi et hyperspectrales et l’inversion en astrophysique avec les données issues de télescopes.
Book Synopsis Inversion de données électromagnétiques par algorithme génétique pour la télédétection en zone forestière by : Mahmoud Kanj
Download or read book Inversion de données électromagnétiques par algorithme génétique pour la télédétection en zone forestière written by Mahmoud Kanj and published by . 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).

This Symposium addressed the scientific advances in quantitative remote sensing in connection with real applications. Its main goal was to assess the state of the art of both theory and applications in the analysis of remote sensing data, as well as to provide a forum for researcher in this subject area to exchange views and report their latest results. In this book 89 of the 262 contributions presented in both plenary and poster sessions are arranged according to the scientific topics selected. The papers are ranked in the same order as the final programme.

Book Synopsis Data Assimilation: Methods, Algorithms, and Applications by : Mark Asch
Download or read book Data Assimilation: Methods, Algorithms, and Applications written by Mark Asch and published by SIAM. This book was released on 2016-12-29 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data assimilation is an approach that combines observations and model output, with the objective of improving the latter. This book places data assimilation into the broader context of inverse problems and the theory, methods, and algorithms that are used for their solution. It provides a framework for, and insight into, the inverse problem nature of data assimilation, emphasizing why and not just how. Methods and diagnostics are emphasized, enabling readers to readily apply them to their own field of study. Readers will find a comprehensive guide that is accessible to nonexperts; numerous examples and diverse applications from a broad range of domains, including geophysics and geophysical flows, environmental acoustics, medical imaging, mechanical and biomedical engineering, economics and finance, and traffic control and urban planning; and the latest methods for advanced data assimilation, combining variational and statistical approaches.

Book Synopsis The Mediterranean region under climate change by : Collectif
Download or read book The Mediterranean region under climate change written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
