Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, nous avons développé deux outils qui sont des supports pour l'optimisation de requêtes. Le premier cherche à améliorer la précision du modèle de coût. Lors de l'optimisation physique, il est important de savoir évaluer de manière assez précise le nombre de pages mémoires auxquelles il faut accéder lors d'un accès disque. Ce nombre de pages dépend bien évidemment en premier lieu du nombre d'éléments (n-uplets ou objets selon que l'on soit dans un système objet ou relationnel) que l'on cherche. Il dépend également de la répartition de ces éléments. Différents types d'éléments sont stockés dans une base de données. Toutefois, il existe une logique qui les fait coexister dans la même base. En général, il existera donc une corrélation entre les différents types de données stockées dans la base. Pour être précis, il faudra prendre en compte cette corrélation quand nous ferons notre évaluation. Notre modélisation prend en compte tous ces paramètres pour calculer l'évaluation du nombre de pages. Le deuxième outil se situe au niveau de l'optimisation logique. Le schéma est un élément central de la base de données. En effet, il permet entre autre de renseigner l'utilisateur sur le contenu de la base de données. Les bases de données semi-structuréesn'imposent pas un schéma préalablement établi des données. En effet, celles-ci étant intégrées de l'extérieur, on ne peut leur imposer une forme prédéfinie. L'utilisateur n'ayant de schéma pour l'aider à formuler sa question, celle-ci pourra donc être assez évasive ou incomplète. Nous développons dans la deuxième partie de cette thèse une structure qui permet la réécriture d'une requête incomplète dans une forme plus classique

Available in PDF, EPUB and Kindle. Book excerpt: A concise resource to the best practices and problem-solving ideas for understanding the airline network planning and scheduling process Airline Network Planning and Scheduling offers a comprehensive resource that is filled with the industry's best practices that can help to inform decision-modeling and the problem-solving process. Written by two industry experts, the book is designed to be an accessible guide that contains information for addressing complex challenges, problems, and approaches that arise on the job. The chapters begin by addressing the complex topics at a broad, conceptual level before moving on to more detailed modeling in later chapters. This approach follows the standard airline planning process and reflects the duties of the day-to-day job of network/schedule planners. To help gain a practical understanding of the information presented, each chapter includes exercises and data based on real-world case studies. In addition, throughout the book there are graphs and illustrations as well as, information on the most recent advances in airline network and planning research. This important resource: Takes a practical approach when detailing airline network planning and scheduling practices as opposed to a theoretical perspective Puts the focus on the complexity and main challenges as well as current practices and approaches to problem-solving and decision-making Presents the information in a logical sequence that begins with broad, conceptual topics and gradually delves into more advanced topics that address modeling Contains international standard airline planning processes, the day-to-day responsibilities of the job, and outlines the steps taken when building an airline network and schedule Includes numerous case studies, exercises, graphs, and illustrations throughout Written for professionals and academics, Airline Network Planning and Scheduling offers a resource for understanding best practices and models as well as the challenges involved with network planning and scheduling.

Above all, the position of the law of tort within the overall system for the protection of legal goods is examined. The focus is on particularly controversial issues and new approaches. Not only is the relationship between breaches of obligations and torts examined, the basic requirements for a claim under tort law"damage and causation"are discussed. An extensive section is devoted to the elements of establishing liability and the question of liability on the side of the victim, (contributory responsibility) is looked at anew. A final section is devoted to the prescription of compensation claims.

Book Synopsis Classical Architecture by : Alexander Tzonis
Download or read book Classical Architecture written by Alexander Tzonis and published by MIT Press. This book was released on 1986-10-16 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating introduction to classical art and architecture is the first book to investigate the way classical buildings are put together as formal structures. It researches the generative rules, the poetics of composition that classical architecture shares with classical music, poetry, and drama, and is enriched by a variety of examples and an extensive analysis of compositional rules. The 205 line drawings make up a discourse of their own, a pictorial text that serves as an introductory theory of composition or basic design aid. Drawing from Vitruvius, the poetics of Aristotle, the theories of classical architecture, music, and poetry since the Renaissance, and the poetics of the Russian formalists, the authors present classical architecture as a coherent system of architectural thinking that is capable of producing a tragic humanistic discourse, a public art with critical, moral, and philosophical meaning.
