Book excerpt: Le sujet de cette thèse se situe à l'intersection des domaines de la robotique mobile et des réseaux de neurones artificiels (RNA). Notre objectif est d'étudier les solutions que peuvent apporter les techniques connexionnistes aux problèmes particuliers posés par la commande automatique d'un robot de type voiture. Ce mémoire se compose de deux parties principales. La première d'entre elles traite des aspects fondamentaux de la commande d'un robot mobile et de l'utilisation des réseaux de neurones artificiels pour la commande de systèmes complexes. Cette première étude nous permet de mettre en évidence les différents points sur lesquels les réseaux de neurones peuvent jouer un rôle dans une architecture de commande conférant une véritable autonomie de mouvements au véhicule, tout en respectant les contraintes de robustesse et de rapidité de réaction induites par l'utilisation d'un robot de la taille et de la vitesse d'une voiture. Nous proposons dans la deuxième partie du mémoire plusieurs contrôleurs permettant d'accroître progressivement l'autonomie du robot. Nous nous intéressons tout d'abord à une tâche simple consistant uniquement à asservir le robot sur une trajectoire de référence issue d'un planificateur. Notre approche autorise une adaptation continue du système face à d'éventuels changements des paramètres du robot ou de son environnement. Afin de permettre la réalisation de manoeuvres sans consignes extérieures, nous proposons également une méthodologie pour la réalisation de contrôleurs basés sur l'utilisation des capteurs externes du véhicule. Notre appoche utilise un modèle alliant des caractéristiques issues de la logique floue et des RNA. Enfin nous montrons comment des tâches complexes peuvent être réalisées à partir de l'enchaînement de plusieurs contrôleurs simples. Notre réalisation du système de sélection de ces contrôleurs, utilisant un RNA récurrent, possède des capacités de robustesse et autorise des réactions très rapides face à l'ensemble des événements extérieurs qui doivent pouvoir être pris en compte.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Renewable Energy for Smart and Sustainable Cities written by Mustapha Hatti and published by Springer. This book was released on 2018-11-23 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features cutting-edge research presented at the second international conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2018, held on 24–26 November 2018, at the High School of Commerce, ESC-Koléa in Tipaza, Algeria. Today, the fundamental challenge of integrating renewable energies into the design of smart cities is more relevant than ever. While based on the advent of big data and the use of information and communication technologies, smart cities must now respond to cross-cutting issues involving urban development, energy and environmental constraints; further, these cities must also explore how they can integrate more sustainable energies. Sustainable energies are a major determinant of smart cities’ longevity. From an environmental and technological standpoint, these energies offer an optimal power supply to the electric network while creating significantly less pollution. This requires flexibility, i.e., the availability of supply and demand. The end goal of any smart city is to improve the quality of life for all citizens (both in the city and in the countryside) in a way that is sustainable and respectful of the environment. This book encourages the reader to engage in the preservation of our environment, every moment, every day, so as to help build a clean and healthy future, and to think of the future generations who will one day inherit our planet. Further, it equips those whose work involves energy systems and those engaged in modelling artificial intelligence to combine their expertise for the benefit of the scientific community and humanity as a whole.

This book was released on 2019-12-24 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Conference on Artificial Intelligence in Renewable Energetic Systems, IC-AIRES2019, 26-28 November 2019, Taghit-Bechar, Algeria. The challenges of the energy transition in the medium term lead to numerous technological breakthroughs in the areas of production, optimal distribution and the rational use of energy and renewable energy (energy efficiency and optimization of consumption, massive electrification, monitoring and control energy systems, cogeneration and energy recovery processes, new and renewable energies, etc.). The fall in the cost of renewable energies and the desire for a local control of energy production are today calling for a profound change in the electricity system. Local authorities are at the center of energy developments by taking into account the local nature of certain energy systems, heat networks, geothermal energy, waste heat recovery, and electricity generation from household waste. On the other side, digital sciences are at the heart of connected objects and intelligent products that combine information processing and communication capabilities with their environment. Digital technology is at the center of new systems engineering approaches (3D modeling, virtualization, simulation, digital prototyping, etc.) for the design and development of intelligent systems. The book deals with various topics ranging from the design, development and maintenance of energy production systems, transport, distribution or storage of energy, optimization of energy efficiency, especially in the use of energy. innovation in the fields of energy production from renewable energies, management of energy networks: electricity, fluids, gas, district heating, energy storage modes: battery, super-capacitors , overseeing energy supply through supervision, control and diagnosis, risk management, as well as the design and management of smart grids: microgrid, smartgrid. This imposes the model of energy empowerment in the advent of smart cities. Empower the world’s most vulnerable energy-poor citizens and establish growing and vibrant socioeconomic communities, by academics, students in engineering and data computing from around the world who have chosen an academic path leading to an electric power and energy engineering and artificial intelligence to advancing technology for the advantage of humanity.

Download or read book Principles of European Contract Law and Italian Law written by Luisa Antoniolli and published by Kluwer Law International B.V.. This book was released on 2005-01-01 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: To provide valuable legal service to persons in today's Europe, practitioners must be conversant in both national and transnational law. At the European level, the Principles of European Contract Law (PECL) are an increasingly important element of contract law, together with national contract law, as contained in Civil Codes and various national statute. Accordingly, Kluwer Law International has initiated a series of volumes, under the direction of prof. Hondius of the University of Utrecht, comparing PECL with the most important European legal systems. This volume on Italian law is the second in the series. Using a straightforward comparative method, the editors¿ analysis not only reveals a significant area of convergence between the PECL and Italian contract law, but also highlights the main differences between the two bodies of rules. The reasons for these differences, both legal and non-legal (such as historical, social, economic), are clearly set forth. The book provides complete texts, with annotations, of the PECL and the corresponding Italian rules. The presentation proceeds as follows: general provisions (scope of application, general duties, terminology)formation of contracts (general provisions, offer and acceptance, liability for negotiations)authority of agents (general provisions, direct and indirect representation)validityinterpretationcontents and effectsperformancenon-performance and remedies in generalparticular remedies for non-performance (right to performance, withholding performance, termination of the contract, price reduction, damages and interest) The editors commentary includes extensive reference to case law and legal doctrine at all essential points. In this way they provide a comprehensive description of the law in action as well as its evolving trends. In addition, incisive essays by two leading experts in the field of comparative law, prof. Rodolfo Sacco and prof. Michael Joachim Bonell, analyse the relationship of the PECL and Italian law and its wider framework in the harmonisation of private law at the European and international levels. The book is a valuable handbook and guide for both foreign and Italian lawyers. For non-Italian lawyers, be they practitioners or academics, it provides a concise but complete and up-to-date outline of current Italian contract law, organized on the basis of a system (PECL) with which many European lawyers are familiar. For Italian lawyers, it offers a clearer insight into a wider European legal contract system whose importance in the evolution of a common European private law is growing rapidly.

Download or read book The Geometry of Multiple Images written by Olivier Faugeras and published by MIT Press. This book was released on 2001 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Over the last forty years, researchers have made great strides in elucidating the laws of image formation, processing, and understanding by animals, humans, and machines. This book describes the state of knowledge in one subarea of vision, the geometric laws that relate different views of a scene. Geometry, one of the oldest branches of mathematics, is the natural language for describing three-dimensional shapes and spatial relations. Projective geometry, the geometry that best models image formation, provides a unified framework for thinking about many geometric problems are relevant to vision. The book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Images play a prominent role in computer communications. Producers and users of images, in particular three-dimensional images, require a framework for stating and solving problems. The book offers a number of conceptual tools and theoretical results useful for the design of machine vision algorithms. It also illustrates these tools and results with many examples of real applications.
