Book Description
L'objet de cette thèse est la résolution des problèmes de gestion qui se posent lors de l'utilisation d'un système de voitures électriques mises en libre service en complément des transports en commun. Au bout d'un certain nombre de courses, il se peut qu'un site soit incapable (à cause du nombre limite de places de parking) d'accueillir de nouvelles voitures. La situation inverse peut aussi se produire ; c'est le cas lorsqu'un site est dans l'incapacité de répondre aux demandes des clients et de leur fournir des voitures. Nous proposons deux méthodes afin de redistribuer les voitures présentes dans les sites. La première, appelée redistribution préventive, comprend trois étapes. Grâce à la simulation, nous déterminons le moment ou une redistribution est nécessaire. Ensuite, par le biais de la programmation linéaire, nous calculons le nombre de voitures qu'il faut déplacer. Finalement, nous établissons les trajets que les camions (qui transportent les voitures) doivent suivre. La seconde méthode, appelée redistribution permanente, consiste à faire passer cycliquement un camion dans les différents sites, et à chaque passage de celui-ci, à prendre une décision. Le second problème considéré est la recharge de voitures électriques. Nous calculons un seuil de disponibilité au dessous duquel les voitures ne sont pas autorisées à quitter le site, et ceci afin de limiter les pannes d'énergie pendant les courses. Nous enchaînons avec le problème de la gestion des plots de recharge. Ce problème apparaît lorsque le nombre de plots est inférieur au nombre de voitures présentes. Nous déterminons le moment ou le processus de recharge d'une voiture pouvant être interrompu, la voiture peut alors être déplacée et laisser la place à une autre voiture. La dernière partie de ce travail consiste à regrouper les différents logiciels développés précédemment et à fournir un logiciel de simulation intégrant tous les aspects du programme

Book Description
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

Book Description
This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Book Description
This book is about one of the most controversial dilemmas of contract law: whether or not the unexpected change of circumstances due to the effects of financial crises may under certain conditions be taken into account. Growing interconnectedness of global economies facilitates the spread of the effects of the financial crises. Financial crises cause severe difficulties for persons to fulfill their contractual obligations. During the financial crises, performance of contractual obligations may become excessively onerous or may cause an excessive loss for one of the contracting parties and consequently destroy the contractual equilibrium and legitimate the governmental interventions. Uncomfortable economic climate leads to one of the most controversial dilemmas of the contract law: whether the binding force of the contract is absolute or not. In other words, unstable economic circumstances impose the need to devote special attention to review and perhaps to narrow the binding nature of a contract. Principle of good faith and fair dealing motivate a variety of theoretical bases in order to overcome the legal consequences of financial crises. In this book, all these theoretical bases are analyzed with special focus on the available remedies, namely renegotiation, rescission or revision and the circumstances which enables the revocation of these remedies. The book collects the 19 national reports and the general report originally presented in the session regarding the Effects of Financial Crises on the Binding Force of Contracts: Renegotiation, Rescission or Revision during the XIXth congress of the International Academy of Comparative Law, held in Vienna, July 2014.
