Mechanical modelling of microwave sintering and experimental validation on an alumina powder

Maxence Renaux, Damien Méresse, Julien Pellé, Anthony Thuault, Céline Morin, Christelle Nivot, Christian Courtois

Microwave sintering (MW) allows fast heating (≤30 min) and densification of ceramic materials, like alumina Al2O3. In order to predict the final material properties (density, size and grain size) the mechanical SOVS (Skorohold Olevsky Viscous Sintering) model is adapted and validated for…

Human and Cobot Cooperation Ethics: The Process Management Concept of the Production Workplace

Felicita Chromjakova, Damien Trentesaux, Michael Adu Kwarteng

The competitiveness of modern companies depends today on the ability to implement digitised technologies into production processes in human-friendly ways. The aim of this paper is to analyse ethical aspects of human-cobot cooperation in industrial production and to design a process standard aimed…

Observer-based Robust Train Speed Estimation Subject to Wheel-Rail Adhesion Faults

Fawzia Bouchama, Denis Berdjag, Michael Defoort, Jimmy Lauber

This paper deals with the problem of robust longitudinal speed estimation for rail transportation system under wheel-adhesion related faults that corrupt speed measurements and lead to poor closed-loop behavior. Two observers are used: the first one is a sliding mode filtering differentiator which…

EdgeMark Menu: A 1D Menu for Curved Edge Display Smartphones

Hanaë Rateau, Yosra Rekik, Edward Lank, Keiko Katsuragawa

While many smartphones now include a waterfall (or curved edge) display, this edge is rarely exploited for input. In this paper, we introduce EdgeMark, a thumb-operated, one-handed, gestural menu to provide rapid and subtle access to commands. In a first study, we assess the movement range of the…

Computational Fluid Dynamics Investigation of the Thermal Performances of a Swirler with Profiled Blades

Bruce Indurain y Urricelqui, François Beaubert, Sylvain Lalot, David Uystepruyst

Numerical simulations were carried out to investigate the swirling decaying flow generated by a novel axial guide vane swirler with profiled blades and no supporting device in a tube and its effect on heat transfer and pressure drop compared to a developed turbulent flow in a no swirl tube.…

Évaluation de l'énergie et de la distance pour les attaques de brouillage dans les réseaux sans fil

Emilie Bout, Valeria Loscri, Antoine Gallais

Composés d'appareils fortement limités en ressources, les réseaux sans fil présentent de nombreuses vulnérabilités. Leur déploiement croissant dans des secteurs et infrastructures critiques impose des mesures de sécurité adaptées. Parmi les menaces de sécurité les plus graves dans le domaine…

Protection contre les fuites de données : un environnement micro-services sécurisé

Loïc Miller, Pascal Mérindol, Antoine Gallais, Cristel Pelsser

Les fuites de données au repos sont malheureusement courantes et en augmentation, entrainant des pertes de profits pour les entreprises ou le non-respect de confidentialité de données personnelles sensibles. La récente montée en puissance des micro-services, en tant que paradigme de déploiement…

Plaidoyer pour une éthique des humanités numériques

Bako Rajaonah, Enrico Zio

Partons du constat surprenant de l’absence d’un code éthique des humanités numériques alors que foisonnent diverses éthiques appliquées visant à encadrer les chercheurs, ingénieurs, praticiens. En mettant de côté l’effet mode de l’éthique, n’y aurait-il pas nécessité de construire un code d’éthique…, Let us start with the surprising observation that there is no code of ethics for digital humanities, while various applied ethics aiming to provide a framework for researchers, engineers and practitioners abound. Putting aside the fashionable effect of ethics, is it not necessary to build a code…

Observer-based freight train control to reduce coupler strain and low adhesion issues

Fawzia Bouchama, Smail Houti, Denis Berdjag, Michael Defoort, Jimmy Lauber

This paper deals with the control design for freight trains, with the objective to reduce coupler failures and issues that might arise from low wheel-track adhesion. Since train cars are not equipped with position sensors, a cascade of observers is used to obtain finite-time estimations of in-train…

Leader-following Formation Control of Second-order Autonomous Unmanned Systems under Switching Topologies

Sandeep Kumar Soni, Ankit Sachan, Shyam Kamal, Sandip Ghosh, Mohamed Djemai

A distributed formation control is proposed for the leader-following problem of second-order autonomous unmanned systems (AUSs) under switching topologies. A leader dynamics is assumed to be time-varying. Considering practical situations, the kinematic equations are established for the AUSs.…
