Repairnator patches programs automatically

Martin Monperrus, Simon Urli, Thomas Durieux, Matias Martinez, Benoit Baudry, Lionel Seinturier

Repairnator is a bot. It constantly monitors software bugs discovered during continuous integration of open-source software and tries to fix them automatically. If it succeeds in synthesizing a valid patch, Repairnator proposes the patch to the human developers, disguised under a fake human...

Identification of critical success factors, risks and opportunities of Industry 4.0 in SMEs

Alexandre Moeuf, Samir Lamouri, Robert Pellerin, Simon Tamayo, Estefania Tobon Valencia, Romain Eburdy

SMEs, as prominent actors in industry, must meet more and more complex customer expectations. Recently, the concept of Industry 4.0 has emerged. This new approach enables the control of production processes by providing real-time synchronisation of flows and by enabling the production of unitary...

A framework to help decision makers to be environmentally aware during the maintenance of cyber physical systems

Olivier Sénéchal, Damien Trentesaux

For decades, maintenance of facilities and equipment, as well as related activities (from fault detection to prognostics and health management), has a proven impact on efficiency of production systems and is thus still the subject of numerous developments (from corrective to proactive maintenance...

Investigation of the dynamics in separated turbulent flow

Fawzi Fadla, Frédéric Alizard, Laurent Keirsbulck, Jean-Christophe Robinet, Jean-Philippe Laval, Jean-Marc Foucaut, Camila Chovet, Marc Lippert

Dynamical behavior of the turbulent channel flow separation induced by a wall-mounted two-dimensional bump is studied, with an emphasis on unsteadiness characteristics of vortical motions evolving in the separated flow. The present investigations are based on an experimental approach and Direct...

Does Unilateral Lower Limb Amputation Influence Ankle Joint Torque in the Intact Leg?

Emilie Simoneau-Buessinger, Jennifer Jakobi, Anis Toumi, Anne Mathys, Jennifer Bassement, Franck Barbier, Sebastien Leteneur

Objective To investigate ankle torque and steadiness in the intact leg of transtibial and transfemoral unilateral amputees. Design Comparative study. Setting Medical rehabilitation centers. Participants Fifteen persons with a unilateral transfemoral amputation, 8 persons with a transtibial...

Frequency coherence analysis of postural balance in able-bodied and in non-treated adolescent idiopathic scoliotic girls

Sebastien Leteneur, Sylvain Cremoux, Paul Allard, Emilie Simoneau-Buessinger, Nader Farahpour, Franck Barbier

Background: This study test if the frequency coherence calculated for the overall, low and high frequency bandwidths of the center of pressure excursions and free-moment calculated during standing balance are similar between scoliotic and non-scoliotic girls and if the coherence values within each...

Sliding mode control applied to a square-back Ahmed body

Camila Chovet, Maxime Feingesicht, Baptiste Plumejeau, Marc Lippert, Laurent Keirsbulck, Franck Kerhervé, Andrey Polyakov, Jean-Pierre Richard, Wafik Abassi, Jean-Marc Foucaut

We consider the first closed-loop separation control experiment on an Ahmed body using a robust, model-based strategy called "sliding mode control" (SMC). The goal is to reduce and further maintain the aerodynamic drag of the square-back Ahmed body flow at Re h = 9 × 10 4 (based on the...

A computational approach to design new tests for viscoplasticity characterization at high strain-rates

Pascal Bouda, Bertrand Langrand, Delphine Notta-Cuvier, Eric Markiewicz, Fabrice Pierron

Rate-dependent behaviour characterization of metals at high strain rate remains challenging mainly because of the strong hypotheses when tests are processed with statically determinate approaches. As a non-standard methodology, Image-Based Inertial Impact (IBII) test has been proposed to take...

Do Older People Accurately Estimate the Length of Their First Step during Gait Initiation?

Delphine Caffier, Marion Luyat, Sylvain Cremoux, Christophe Gillet, Ghassan Ido, Franck Barbier, Janick Naveteur

Advancing age is associated with a decrease in step length. In line with previous studies showing that older adults often overestimate their motor abilities, we investigate whether older adults overestimate the length of their first step during gait initiation. The underlying effect could be a...

Yet another low‐level agent handler

Fabrizio Nunnari, Alexis Heloir

YALLAH is a framework for the creation of real-time interactive virtual humans. Its production pipeline supports the continuous, parallel development of both the character and the software, and allows users for the deployment of a new character in a few hours of work. YALLAH is based on freely...
