Review on the performances, foaming and injection molding simulation of natural fiber composites

Jianghu Zhan, Jiao Li, Guilong Wang, Yanjin Guan, Guoqun Zhao, Jun Lin, Hakim Naceur, Daniel Coutellier

Recently, natural fiber becomes an alternative to the synthetic fiber for the composites used in aerospace, automotive, sports, packaging and so on, due to its inherent characteristics like biodegradablity, renewablity, high-specific strength and specific modulus. However, there are still many...

Numerical Study of the Toughness of Complex Metal Matrix Composite Topologies

Julie Lemesle, Cédric Hubert, Maxence Bigerelle

Fracture toughness tests (compact tension) of a dual material composed of a structured Metal Matrix Composite (MMC) (martensitic steel and titanium carbides, named MS-TiC) surrounded by martensitic steel (MS) are simulated with a Discrete Elements Model (DEM) developed with the GranOO Workbench....

Ethics of Autonomous Intelligent Systems in the Human Society: Cross Views from Science, Law and Science-Fiction

Damien Trentesaux, Raphaël Rault, Emmanuel Caillaud, Arnaud Huftier

The objective of this paper is to discuss issues and insights relevant to the ethical behaviour of future autonomous intelligent system merged in the human society. This discussion is done at the frontier of three domains: science, as the mean to imagine and design innovative technological...

Copositive Conditions for LMI-Based Controller and Observer Design

Juan Carlos Arceo Luzanilla, Jimmy Lauber

In this report we illustrate that nonlinear control and observer design can be described as a Positivstellensatz problem, we consider a quadratic candidate function to stabilize nonlinear systems that have been modeled via the nonlinear sector methodology as an exact convex representation. New...

Adapted visual analytics process for intelligent decision-making

Hela Ltifi, Emna Benmohamed, Christophe Kolski, Mounir Ben Ayed

The theoretical and practical researches on Visual Analytics for intelligent decision-making tasks have remarkably advanced in the past few years. Intelligent Decision Support Systems (IDSS) introduce effective and efficient paths from raw data to decision by involving visualization and data mining...

Mechanical properties of WC/Co-CNT HVOF sprayed coatings

Mariana H. Staia, Alberto Mejias, José Gregorio La Barbera-Sosa, Eli Saúl Puchi-Cabrera, C. Villalobos-Gutiérrez, Yucelys Yessenia Santana de La Barbera, Alex Montagne, Alain Iost, M. A. Rodríguez

Coatings based on WC–12Co, with and without the reinforcement of carbon nanotubes (CNTs) have been deposited by means of the HVOF thermal spraying technique on a SAE 1020 steel substrate. The aim of the present study is to evaluate in detail the influence of the 36 h milling time on both feedstock...

Observer-based output feedback consensus protocol for double-integrator multi-agent systems under intermittent sampled position measurements

Dylan Poulsen, Michael Defoort, Mohamed Djemai

This paper deals with the leader-follower consensus problem for double-integrator multi-agent systems using sampled position data information. An observer-based output feedback controller is designed to study this problem while taking into account intermittent sensor failures. The non-uniformity...

Conception d’architectures de pilotage “non centralisées”: Contributions et collaborations

Damien Trentesaux

Cette présentation décrit les principaux concepts développés dans l'équipe autour des architectures de pilotage "non centralisées", c'est à dire composées d'entités décisionnelles hiérarchisées, distribuées ou décentralisées qui inter-agissent au sein d'une...

Distributed global actuator fault-detection scheme for a class of linear multi-agent systems with disturbances

Anass Taoufik, Michael Defoort, Mohamed Djemai, Krishna Busawon, Juan Diego Sanchez-Torres

This paper proposes a distributed methodology for the detection of actuator faults in a class of linear multi-agent systems in the presence of disturbances. A cascade of fixed-time observers is introduced to give an exact estimate of the global system state for each agent whereby the convergence...

A Distributed Observer-Based Cyber-Attack Identification Scheme in Cooperative Networked Systems under Switching Communication Topologies

Anass Taoufik, Michael Defoort, Krishna Busawon, Laurent Dala, Mohamed Djemai

This paper studies an approach for detecting cyber attacks against networked cooperative systems (NCS) that are assumed to be working in a cyber-physical environment. NCS are prone to anomalies both due to cyber and physical attacks and faults. Cyber-attacks being more hazardous given the...
