Les questions de développement durable et de projection des besoins futurs favorisent l'apparition de nouvelles technologies de production d'énergie et entraînent un changement de comportement des usagers. Ce livre contribue à une meilleure appréhension de ces technologies émergentes de production d'électricité. Il analyse leurs enjeux, leurs sources et leurs moyens de conversion électrique. Suivant une approche didactique et générale, cet ouvrage présente : - les systèmes de production d'électricité à partir de ressources énergétiques renouvelables des petites aux moyennes puissances (jusque 100 à 200 MW), - les notions électrotechniques de base nécessaire à la compréhension des caractéristiques de fonctionnement de ces convertisseurs, - les contraintes et problèmes d'intégration dans les réseaux électriques de ces moyens de production.

Congenital heart defects are among the most common birth defects and the leading cause of birth defect-related deaths. Most cardiac defects have some manifestation in the morphology of cardiac electrical signals, which are recorded by electrocardiography and are believed to contain much more information as compared with conventional sonographic methods. Therefore, the noninvasive study of fetal cardiac signals can provide an effective means of monitoring the well-being of the fetal heart and may be used for the early detection of cardiac abnormalities. In previous studies, various methods have been developed for the processing and extraction of fetal electrocardiogram (ECG) signals recorded from the maternal body surface. However, due to the low signal-to-noise ratio of these signals, the application of fetal electrocardiography has been limited to heartbeat analysis and invasive ECG recordings during labor. In this research, the objective is to improve the signal processing aspects of fetal cardiography and to provide better insights of this problem, by developing new techniques for the modeling and filtering of fetal ECG signals recorded from an array of electrodes placed on the maternal abdomen. The basic idea behind the developed methods is to use a priori information about cardiac signals, such as their pseudo-periodic structure, to improve the performance of the currently existing techniques and to design novel filtering techniques that are customized for cardiac signals. Due to the overlap of the fetal signals and interferences/noises in different domains, the methods that use the information in only one of these domains do not usually succeed in extracting the fetal ECG. Therefore, we design methods that use the information from various domains, in order to improve the quality of the extracted signals. Theoretically, the proposed methods are combinations of morphological models of the ECG, ad hoc Bayesian filtering techniques based on estimation theory, and special classes of spatial filters adapted from the blind and semi-blind source separation context. It is shown that due to the generality of the proposed methods, the same procedures are also applicable to multichannel adult ECG recordings and can be used in real-time cardiac monitoring systems. Moreover, the developed methods are based on the cardiac signal morphology without going into the details of volume conduction theory and the conductivities of the propagation media. Hence, the same methods are applicable to other cardiac monitoring modalities such as the magnetocardiogram (MCG), which are morphologically similar to the ECG. We specifically present a case study on the extraction of twin fetal MCG signals. We also present an advanced deflation technique, which is able to separate subspaces of desired signals from degenerate mixtures of signal and noise. This idea has found various applications in other contexts.
