Book excerpt: Dans un contexte d'électrification massive de nos modes de vie (Transports, Industrie, activités tertiaires), des structures de conversion d'énergie toujours plus performantes ( en terme de sobriété, d'efficacité ou ayant un moindre impact sur l'environnement) sont recherchées. Limitées par l'accès et l'utilisation de matériaux rares ou polluants mais également par leurs coûts de mise en œuvre, nos technologies ont été constamment améliorées et optimisées depuis un siècle mais atteignent aujourd'hui une asymptote. De nouvelles technologies en rupture présentent un moyen de faire des bonds significatifs dans cette évolution mais demandent à être découvertes, analysées, modélisées, vérifiées et mises en valeur par les laboratoires de recherche pour être intégrées par le monde industriel. Cette thèse porte sur l'étude, la modélisation et le dimensionnement d'un système innovant et original associant une électronique de puissance non-linéaire et une machine électrique. Cette technologie, encore très peu étudiée aujourd'hui, offre de nouveaux degrés de liberté dans la conception de la chaine de conversion électromécanique pour la génération d'électricité ou la motorisation par exemple.Ce travail ambitionne donc de proposer une lecture claire du fonctionnement non linéaire de la chaine de conversion proposée et d'en comprendre les bénéfices mais aussi les limites et les coûts. Par non-linéaire, on entend ici que ces systèmes sont capables de modifier la topologie profonde ou fondamentale du circuit ou système dans lequel ils sont mis en œuvre et sont capables d'agir sur la dynamique des tensions et courants. Ils peuvent ainsi agir sur la gestion de l'énergie réactive, le facteur de puissance mais aussi sur les niveaux de tensions et courants et par extension de la puissance active et d'en garantir le contrôle.Le travail synthétisé dans ce manuscrit permet dans un premier temps de recenser les rares exemples adoptant cette philosophie et d'en jeter les bases, permettant à différentes topologies inédites d'y être identifiées. Dans un second volet, une méthodologie de modélisation en phase d'esquisse du système entier est présentée et testée permettant de mener des simulations et des dimensionnements. Fort de cette méthode, un troisième volet conceptuel porte sur son application aux machines électriques et démontre les nouveaux compromis et nouvelles performances possibles, comme l'augmentation sensible des performances mécaniques ou la réduction du volume d'aimant nécessaire. Enfin, un dernier volet expérimental permet de vérifier en pratique les différents résultats théoriques grâce à la mise en place d'un banc d'essai à échelle industrielle.

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.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

Download or read book Adhesion between polymers and concrete Adh sion entre polym res et b ton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
