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…
