Book excerpt: Le travail a été réalisé au Cran (ENSEM) dans l'équipe de recherche méthodologie de conception et sûreté de fonctionnement des systèmes de commande. Dans une première partie, les travaux antérieurs de l'équipe sont rappelés : élaboration d'une méthode de conception des systèmes de commande pour les processus rapides que sont les convertisseurs électromécaniques (association d'électronique de puissance et de machines électriques). Cette méthode en 3 étapes fait largement appel aux réseaux de Petri interprétés et montre l'intérêt d'intégrer dès le début de la conception les problèmes de sûreté de fonctionnement. La situation du projet sur lequel l'auteur a travaillé est également présentée : un multiprocesseur rapide dédié à la commande des machines électriques. Dans la seconde partie, l'étude et la réalisation partielle permettant la démonstration de faisabilité, du système de commande tolérant ses fautes par reconfiguration est présentée. Cette étude a été menée en suivant scrupuleusement la méthode proposée. Elle met en évidence les problèmes à résoudre pour reconfigurer la commande tant logicielle que matérielle : détection des erreurs dans les processeurs par diagnostic interne ou par validation des échanges d'informations, isolement du processeur défaillant, reprise de la commande en performances dégradées par des algorithmes simplifiés, problèmes de l'initialisation de ces algorithmes, problème de la sûreté du système gérant la reconfiguration. L'intérêt de cette solution est d'obtenir une bonne sûreté de fonctionnement Sna s’introduire une redondance massive dans le système de commande. La partie expérimentale a été menée à terme avec un pont de Graetz réversible alimentant un moteur à courant continu, et des résultats intéressants ont été obtenus par simulation d'erreurs dans le système de commande

Available in PDF, EPUB and Kindle. Book excerpt: The production of a new version of any book is a daunting task, as many authors will recognise. In the field of computer science, the task is made even more daunting by the speed with which the subject and its supporting technology move forward. Since the publication of the first edition of this book in 1981 much research has been conducted, and many papers have been written, on the subject of fault tolerance. Our aim then was to present for the first time the principles of fault tolerance together with current practice to illustrate those principles. We believe that the principles have (so far) stood the test of time and are as appropriate today as they were in 1981. Much work on the practical applications of fault tolerance has been undertaken, and techniques have been developed for ever more complex situations, such as those required for distributed systems. Nevertheless, the basic principles remain the same.

Available in PDF, EPUB and Kindle. Book excerpt: The growing complexity of modern software systems increases the di?culty of ensuring the overall dependability of software-intensive systems. Complexity of environments, in which systems operate, high dependability requirements that systems have to meet, as well as the complexity of infrastructures on which they rely make system design a true engineering challenge. Mastering system complexity requires design techniques that support clear thinking and rigorous validation and veri?cation. Formal design methods help to achieve this. Coping with complexity also requires architectures that are t- erant of faults and of unpredictable changes in environment. This issue can be addressed by fault-tolerant design techniques. Therefore, there is a clear need of methods enabling rigorous modelling and development of complex fault-tolerant systems. This bookaddressessuchacuteissues indevelopingfault-tolerantsystemsas: – Veri?cation and re?nement of fault-tolerant systems – Integrated approaches to developing fault-tolerant systems – Formal foundations for error detection, error recovery, exception and fault handling – Abstractions, styles and patterns for rigorousdevelopment of fault tolerance – Fault-tolerant software architectures – Development and application of tools supporting rigorous design of depe- able systems – Integrated platforms for developing dependable systems – Rigorous approaches to speci?cation and design of fault tolerance in novel computing systems TheeditorsofthisbookwereinvolvedintheEU(FP-6)projectRODIN(R- orous Open Development Environment for Complex Systems), which brought together researchers from the fault tolerance and formal methods communi- 1 ties.

Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

Explains the contributions of complexity theory to philosophyof education, curriculum, and educational research Brings together new research by an international team ofcontributors Debates issues ranging from the culture of curriculum, to theimplications of work of key philosophers such as Foucault and JohnDewey for educational change Demonstrates how social scientists and social and educationpolicy makers are drawing on complexity theory to answer questionssuch as: why is it that education decision-makers are so resistantto change; how does change in education happen; and what does ittake to make these changes sustainable? Considers changes in use of complexity theory; developedprincipally in the fields of physics, biology, chemistry, andeconomics, and now being applied more broadly to the socialsciences and to the study of education
