Available in PDF, EPUB and Kindle. Book excerpt: Dans la conception des circuits électroniques les variations statistiques des valeurs des paramètres des circuits doivent être prises en compte car elles ont un impact sur la qualité des circuits fabriques. Ces fluctuations statistiques essentiellement dues au processus de fabrication des tolérances, induisent des variations dans les réponses des circuits fabriqués. Le rendement de fabrication, qui est la proportion des circuits fabriqués répondant à un ensemble de contraintes d'acceptabilité spécifiées par le concepteur, est d'un intérêt considérable. Obtenir un rendement acceptable est l'un des principaux objectifs d'un concepteur de circuits électroniques. La méthode de Monte-Carlo a été utilisée pour simuler les variations dans les paramètres des composants ainsi que pour estimer le rendement de fabrication. Cette méthode est choisie a cause de sa généralité et de sa faible dépendance des variables stochastiques. Un programme fondée sur cette méthode a été élaboré et couplé au simulateur SPICE-PAC dont la structure modulaire se prête mieux aux exigences de l'analyse statistiques. Lorsque le rendement de fabrication est faible, il est nécessaire de l'améliorer. C’est la méthode des centres de gravite qui a été utilisée pour optimiser le rendement. L’échantillonnage statistique est amélioré grâce à la méthode des points communs. Malgré que la méthode des centres de gravite soit robuste et d'une utilisation aisée, elle peut être piégée dans optimum local du rendement. Pour résoudre ce problème, nous avons propose une approche d'optimisation du rendement de fabrication qui combine la méthode des centres de gravite et la méthode du recuit simulé

Download or read book Food security and nutrition in the age of climate change written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-17 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: After steadily declining for over a decade, global hunger is on the rise again, while various forms of malnutrition coexist. Climate change is already exacerbating this grim picture, which is why food security and food production will be a major focus of the Intergovernmental Panel on Climate Change’s 6th Assessment Cycle. Thanks to the participation of 250 experts from all around the world, the International Symposium on Food Security and Nutrition in the Age of Climate Change highlighted the importance of food and agricultural systems in the fight against climate change and presented concrete multi-sector solutions to address this global issue. The event placed special emphasis on the regional realities of West Africa and the Canadian North, as well as to the presence of young people and members of Indigenous and Northern communities directly affected by these issues. The summaries of these four days of plenaries, interactive workshops, and special events have been grouped under seven major themes for this publication: 1) Climate change, food security and nutrition: the issues; (2) The agriculture sectors in the context of climate change; (3) Food systems in the face of climate change; (4) Natural resources: challenges and solutions; (5) Food security and nutrition in a changing North; (6) Summary of solutions; (7) Strengthening and adapting regional and international cooperation.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.
