Book Description
LE RADAR A RESEAU PHASE RIAS, DONT EST ICI EXPOSE LE PRINCIPE DE FONCTIONNEMENT, NECESSITE DES TECHNIQUES DE TRAITEMENT DU SIGNAL JORS DE PORTEE DES TECHNOLOGIES TRADITIONNELLES. LE TRAITEMENT DES SIGNAUX DU RIAS CONSISTE POUR L'ESSENTIEL EN UNE TRANSFORMATION DE FOURIER A TRES HAUTE CADENCE. LE VOLUME DE CALCUL NECESSIRE EST EVALUE ET ATTEINT ENVIRON 10#1#2 OPERATIONS COMPLEXES PAR SECONDE. UNE ARCHITECTURE POUR UN PROCESSEUR OPTIQUE FONCTIONNANT EN LUMIERE INCOHERENTE EST PROPOSEE POUR RESOUDRE CE PROBLEME. C'ES UN SYSTEME MATRICIEL A "PROJECTION D'OMBRE", MASSIVEMENT PARALLELE, SIMPLE ET METTANT EN UVRE DES COMPOSANTS OPTOELECTRONIQUES PERFORMANTS. LA CONCEPTION ET L'OPTIMISATION DU SYSTEME SONT PARTICULIEREMENT DETAILLEES, LES PROBLEMES DE DIFFRACTION ET DE BILAN DE FLUX SE REVELANT LES PLUS CRUCIAUX. UNE COMPARAISON EST EFFECTUEE AVEC D'AUTRES ARCHITECTURES ENVISAGEABLES, MONTRANT LES AVANTAGES DU SYSTEME ETUDIE. LES RESULTATS EXPERIMENTAUX OBTENUS SUR UN PROTOTYPE SONT PRESENTES. ILS MONTRENT LA BONNE ADEQUATION DES TECHNIQUES OPTIQUES ANALOGIQUES AU PROBLEME POSE. ENFIN L'APPLICABILITE DE L'ARCHITECTURE PROPOSEE A D'AUTRES DOMAINES D'APPLICATION EST EXAMINEE, EN PARTICULIER EN CE QUI CONCERNE LA REALISATION DE MACHINES NEURONALES

Book Description
Photonics has long been considered an attractive substrate for next generation implementations of machine-learning concepts. Reservoir Computing tremendously facilitated the realization of recurrent neural networks in analogue hardware. This concept exploits the properties of complex nonlinear dynamical systems, giving rise to photonic reservoirs implemented by semiconductor lasers, telecommunication modulators and integrated photonic chips.

Book Description
The book summarizes the state-of-the-art of research on control of self-organizing nonlinear systems with contributions from leading international experts in the field. The first focus concerns recent methodological developments including control of networks and of noisy and time-delayed systems. As a second focus, the book features emerging concepts of application including control of quantum systems, soft condensed matter, and biological systems. Special topics reflecting the active research in the field are the analysis and control of chimera states in classical networks and in quantum systems, the mathematical treatment of multiscale systems, the control of colloidal and quantum transport, the control of epidemics and of neural network dynamics.

Book Description
Bridging the gap between laser physics and applied mathematics, this book offers a new perspective on laser dynamics. Combining fresh treatments of classic problems with up-to-date research, asymptotic techniques appropriate for nonlinear dynamical systems are shown to offer a powerful alternative to numerical simulations. The combined analytical and experimental description of dynamical instabilities provides a clear derivation of physical formulae and an evaluation of their significance. Starting with the observation of different time scales of an operating laser, the book develops approximation techniques to systematically explore their effects. Laser dynamical regimes are introduced at different levels of complexity, from standard turn-on experiments to stiff, chaotic, spontaneous or driven pulsations. Particular attention is given to quantitative comparisons between experiments and theory. The book broadens the range of analytical tools available to laser physicists and provides applied mathematicians with problems of practical interest, making it invaluable for graduate students and researchers.

Book Description
Water Resources in the Mediterranean Region summarizes and collates scientific developments around water resources in the Mediterranean socio-economic environment through a multidisciplinary framework synthesizing hydrology, hydrogeology, climate, bioclimatology, economics, and geography. As such, it provides essential information for any reader looking to learn more about the Mediterranean which is experiencing the impact of climate change and concurrent complex issues of anthropogenic effects, especially in agriculture and other resource uses. Water Resources in the Mediterranean Region covers different challenges in the issue of the evolution of water resources in the Mediterranean. It is intended for PhD students, research scientists, and managers interested in new solutions and approaches for water management and in the forecast of future water dynamics. Offers multidisciplinary content providing global visions of the challenges faced in the Mediterranean region Presents fundamental and operational studies, providing the reader with information on how to implement these actions and results themselves Written in a pedagogical manner, allowing for ease of reading for both researchers and water managers
