Abstract:

Dans cette thèse, nous étudions le problème de l’analyse de signatures de pannes dans le domaine de la maintenance avionique, afin d’identifier les défaillances au sein d’équipements en panne et suggérer des actions correctives permettant de les réparer. La thèse a été réalisée dans le cadre d’une convention CIFRE entre Thales Research & Technology et l’Université Paris-Sud. Les motivations sont donc à la fois théoriques et industrielles. Une signature de panne devrait fournir toutes les informations nécessaires pour identifier, comprendre et réparer la panne. Pour comprendre le mécanisme

Abstract:

Artificial Intelligence Lab, Department of MIS, University of Arizona<br>Concept maps (CM) are informal, semantic, node-link conceptual graphs used to represent knowledge in a variety of applications. Algorithms that compare concept maps would be useful in supporting educational processes and in leveraging indexed digital collections of concept maps. Map comparison begins with element matching and faces computational challenges arising from vocabulary overlap, informality, and organizational variation. Our implementation of an adapted similarity flooding algorithm improves matching of CM knowl

IS Security (ISS) has become a key element of business risk management and can itself create competitive advantage. Thus, organisations seek practical approaches to protect the operation of the business. Protecting the functionality of an organisation is a difficult task but it is the responsibility of both senior management and ISS functions to do so. An analysis of the ISS literature reveals a paucity of research of ISS management, and a need for research to develop a holistic model for managing ISS knowledge to overcome the ever-increasing number of negative security incidents.

Abstract:

Cognitive Maps (CMs) have shown promise as tools for modelling and simulation of knowledge in computers as representation of real objects, concepts, perceptions or events and their relations. This thesis examines the application of fuzzy theory to the expression of these relations, and investigates the development of a framework to better manage the operations of these relations. The Fuzzy Cognitive Map (FCM) was introduced in 1986 but little progress has been made since. This is because of the difficulty of modifying or extending its reasoning mechanism from causality to relations other than

To know whether an operator has formed well integrated KSs, KS evaluation methods must be employed. Many of these methods, however, require subjective, human-rated evaluations.

This study examines how prior knowledge influences future learning. Although it has been established that prior knowledge does have a strong impact on later learning, it is not clear how this effect manifests itself.

Neural network simulations using the cascade-correlation learning algorithm predict that subtasking facilitates learning when it involves learning a function that is compatible
