Une approche unifiée pour la mesure et l'analyse des défauts de forme des pièces mécaniques

To reduce post-processing and improve acquired data quality, it is intended to work out a mesurement system allowing to deliver a description of the acquired geometry in a predefined base of defects. This system will lean on techniques of…

Contributions à la modélisation géométrique du dépôt de matière pour l'élaboration d'un jumeau numérique du procédé WAAM

Wire and arc additive manufacturing processes are rising as they offer high deposition rates and minimize environmental and security issues due to the use of metal powders. Even if the process derived from welding is well-known, its use on robot to…

Physically based bead topology model coupled with electro-mechanical power source model applied for wire and arc additive manufacturing

Metal additive manufacturing (MAM) has grown, in recent years, very strong interest in academic researches as well as industrial applications. Among MAM processes, wire and arc additive manufacturing (WAAM) became very popular through its advantages…

Observer design for labeled finite automata with inputs under stealthy actuators attacks

This paper addresses the problem of cyber-attacks in discrete-event systems framework. Labeled finite state automata with inputs derived from a particular class of Petri net, called Output Synchronized Petri nets, are used to model a given cyber…

Finding the minimal cut sequences of dynamic, repairable, and reconfigurable systems from Generalized Boolean logic Driven Markov Process models

Minimal cut sequences computation is the main objective of qualitative safety analysis of dynamic systems. This article shows first that the existing definitions of minimal cut sequences are not suitable when these systems are both repairable and…
