Book Description
Un enjeu majeur des systèmes d'aide à la décision est d'automatiser le prétraitement de ces informations afin d'en faciliter l'accès. L'objectif de notre travail est la reconnaissance d'occurrences de situations particulières, à partir d'observations issues de plusieurs sources. Dans le processus global de fusion d'informations pour la reconnaissance de situations, nous nous intéressons en particulier à trois étapes. D'abord, les situations que l'on souhaite reconnaître sont modélisées à l'aide du formalisme des graphes conceptuels. Nous bénéficions ainsi des travaux théoriques réalisés sur ce formalisme. Ensuite, l'identification des observations compatibles permet de vérifier que deux observations correspondent à la même situation, avant de tenter de les combiner. Cette identification repose sur l'utilisation de mesures de similarité de graphes adaptables à un domaine d'application spécifique. Enfin, la fusion d'informations repose sur l'utilisation de l'opération de jointure maximale sur les graphes conceptuels. Afin de permettre de fusionner des informations qui ne sont pas complètement identiques, nous relaxons les contraintes d'égalité des valeurs de deux nœuds concepts. La validation de notre travail se divise en deux phases. D'abord, nous mettons en évidence la validité de notre approche ainsi que l'importance d'injecter de la connaissance métier à l'intérieur du processus de fusion. Pour ce faire, nous utilisons notre plate-forme de fusion dans le cadre d'un système de recommandation de programmes télévisés. Ensuite, nous validons la généricité et l'adaptabilité de notre approche en utilisant la plate-forme de fusion sur quatre applications supplémentaires.

Introduction to Information Retrieval
Author: Christopher D. Manning
Publisher: Cambridge University Press
ISBN: 1139472100
Category : Computers
Languages : en
Pages :
Book Description
Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.

Autonomous Mobile Robots and Multi-Robot Systems
Author: Eugene Kagan
Publisher: John Wiley & Sons
ISBN: 1119212863
Category : Technology & Engineering
Languages : en
Pages : 340
Book Description
Offers a theoretical and practical guide to the communication and navigation of autonomous mobile robots and multi-robot systems This book covers the methods and algorithms for the navigation, motion planning, and control of mobile robots acting individually and in groups. It addresses methods of positioning in global and local coordinates systems, off-line and on-line path-planning, sensing and sensors fusion, algorithms of obstacle avoidance, swarming techniques and cooperative behavior. The book includes ready-to-use algorithms, numerical examples and simulations, which can be directly implemented in both simple and advanced mobile robots, and is accompanied by a website hosting codes, videos, and PowerPoint slides Autonomous Mobile Robots and Multi-Robot Systems: Motion-Planning, Communication and Swarming consists of four main parts. The first looks at the models and algorithms of navigation and motion planning in global coordinates systems with complete information about the robot’s location and velocity. The second part considers the motion of the robots in the potential field, which is defined by the environmental states of the robot's expectations and knowledge. The robot's motion in the unknown environments and the corresponding tasks of environment mapping using sensed information is covered in the third part. The fourth part deals with the multi-robot systems and swarm dynamics in two and three dimensions. Provides a self-contained, theoretical guide to understanding mobile robot control and navigation Features implementable algorithms, numerical examples, and simulations Includes coverage of models of motion in global and local coordinates systems with and without direct communication between the robots Supplemented by a companion website offering codes, videos, and PowerPoint slides Autonomous Mobile Robots and Multi-Robot Systems: Motion-Planning, Communication and Swarming is an excellent tool for researchers, lecturers, senior undergraduate and graduate students, and engineers dealing with mobile robots and related issues.

Bringing Fusion to the U.S. Grid
Author: National Academies of Sciences Engineering and Medicine
Publisher:
ISBN: 9780309685382
Category :
Languages : en
Pages :
Book Description
Fusion energy offers the prospect of addressing the nation's energy needs and contributing to the transition to a low-carbon emission electrical generation infrastructure. Technology and research results from U.S. investments in the major fusion burning plasma experiment known as ITER, coupled with a strong foundation of research funded by the Department of Energy (DOE), position the United States to begin planning for its first fusion pilot plant. Strong interest from the private sector is an additional motivating factor, as the process of decarbonizing and modernizing the nation's electric infrastructure accelerates and companies seek to lead the way. At the request of DOE, Bringing Fusion to the U.S. Grid builds upon the work of the 2019 report Final Report of the Committee on a Strategic Plan for U.S. Burning Plasma Research to identify the key goals and innovations - independent of confinement concept - that are needed to support the development of a U.S. fusion pilot plant that can serve as a model for producing electricity at the lowest possible capital cost.

Languages : fr
Pages : 438
Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
