Distributed Passive Fault Tolerant Formation Tracking for Uncertain Second Order Multi-Agent Systems

Anass Taoufik, Michael Defoort, Krishna Busawon, Mohamed Djemai

This paper deals with the problem of distributed passive fault tolerant formation tracking control for cooperative second order multi-agent systems (MASs) subject to disturbances and sensor/actuator faults. The proposed scheme is based on decentralized observers used to robustly estimate the…

Experimental investigation of early strain heterogeneities and localizations in polycrystalline α -Fe during monotonic loading

Adrien Berger, Jean-Francois Witz, Ahmed El Bartali, Tarik Sadat, Nathalie Limodin, Mirentxu Dubar, Denis Najjar

A polycrystalline recrystallized α-Fe specimen was subjected to monotonic tension up to 2 % strain. Local strain was measured all over the width of the specimen thanks to in-situ optical-based Digital Image Correlation with adequate spatial and temporal resolution. With additional knowledge of…

Online driver model parameter identification using the Lyapunov approach based shared control

Mohamed Radjeb Oudainia, Chouki Sentouh, Anh-Tu Nguyen, Jean-Christophe Popieul

The work described in this paper proposes a new conflict minimisation strategy in shared driving control for lane keeping systems (LKS) in intelligent vehicles. This strategy takes into account a dynamic driver model, where the driver’s parameters are identified online using the Lyapunov approach.…, Le travail décrit dans cet article propose une nouvelle stratégie de minimisation des conflits dans le contrôle partagé de la conduite pour les systèmes de maintien de voie (LKS) dans les véhicules intelligents. Cette stratégie prend en compte un modèle de conducteur dynamique, où les paramètres du…

An Analysis of the Security and Privacy Issues of the Neovote Online Voting System

Enka Blanchard, Antoine Gallais, Emmanuel Leblond, Djohar Sidhoum-Rahal, Juliette Walter

Abstract This article provides the first security and privacy analysis of the Neovote voting system, which was used for three of the five primaries in the French 2022 presidential election. We show that the demands of transparency, verifiability and security set by French governmental organisations…

Numerical prediction of the galling of aluminium alloys in cold strip drawing

Oussama Filali, André Dubois, Marcel Moghadam, Chris V Nielsen, Laurent Dubar

A methodology based on finite element computations is proposed to predict the galling onset of aluminium alloys in cold forming. The methodology assumes that galling starts as soon as a finite element in the area of contact has reached a critical damage. The damage is calculated using Xue's…

Theories of Global Collapse: Closing Down or Opening Up the Futures?

Fabrizio Li Vigni, Enka Blanchard, Cyprien Tasset

In this essay, we first ask what kind of rhetorical styles the theories of global collapse have when talking about futures. We claim that these theories manifest in one of three forms: prospective, prophecy, and science-fiction. We then ask if such theories tend to close down or rather open up the…

Évaluation initiale d'un outil d'aide à la communication pour des personnes atteintes de la maladie de Parkinson, Initial evaluation of a communication aid for people with Parkinson’s disease

Káthia Marçal de Oliveira, Taisa Guidini Gonçalves, Sophie Lepreux, Christophe Kolski, Véronique Delcroix, Nejmeddine Allouche, Philippe Pudlo, Yohan Guerrier

La maladie de Parkinson est la deuxième maladie neurodégénérative la plus répandue dans le monde. La qualité de vie et la participation sociale des personnes atteintes de la maladie de Parkinson (MP) sont gravement affectées, non seulement par les symptômes moteurs, mais surtout par les symptômes…, Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease in the world. Quality of life and social participation for people with PD are severely impacted. Because of non-motors symptoms as communication impairments, their speech intelligibility is worsened and as a consequence…

Towards behavioral adaptation for people with intellectual disabilities in a mobility context

Léa Pacini, Sophie Lepreux, Christophe Kolski

Accessibility is one of the major current challenges in the HCI field. The task of wayfinding corresponds to the process of determining and following a path between an origin and a destination. It implies great difficulties for people with intellectual disabilities (ID): Fear of getting lost,…
