Crystallization-induced toughness of rubber-modified polylactide: combined effects of biodegradable impact modifier and effective nucleating agent

Jérémy Odent, Jean-Marie Raquez, Philippe Leclère, Franck Lauro, Philippe Dubois

The co-addition of rubber-like poly(ε-caprolactone-co-D, l-lactide) (P[CL-co-LA]) as impact modifier and N,N′-ethylenebis(stereamide) (EBS) as nucleating agent has here been investigated to tailor both the crystallization and toughness of resulting polylactide (PLA)-based materials. In this work,…

Transient effects on sessile droplet evaporation of volatile liquids

A. Maatar, Soufien Chikh, M. Ait Saada, L. Tadrist

For a very volatile liquid, a generally used quasi-steady diffusion model often fails in representing accurately an evaporation phenomenon. The substrate thermal diffusivity and the liquid volatility rule this assumption. The present study uses an unsteady diffusion model to analyze the effect of…

Augmented observer approach for high-impedance haptic system with time delay

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

Among others measures of performance, a haptic device may be characterized by its behavior in the implementation of a virtual wall in terms of the biggest value of the virtual stiffness leaving stable the device. This value depends on many factors including time delays and the virtual world…

Continuous and Discrete State Estimation for a Class of Nonlinear Switched Systems

Fayssal Arichi, Mohamed Djemai, Cherki Brahim, Noureddine Manamanni

This brief investigates the hybrid observer design fora class of nonlinear switched systems in which the discrete part isgoverned by a Petri net. The proposed hybrid observer representsa combination of a continuous observer based on the second-ordersliding mode approach and a discrete one based on…

Tailoring Polylactide Properties for Automotive Applications: Effects of Co-Addition of Halloysite Nanotubes and Selected Plasticizer

Delphine Notta-Cuvier, Marius Murariu, Jérémy Odent, Rémi Delille, Amani Bouzouita, Jean-Marie Raquez, Franck Lauro, Philippe Dubois

Among currently available bio-based polymers, polylactide (PLA) and its (nano)composites have interesting physical and mechanical properties (high tensile strength and stiffness, good processability, biodegradability …). However, they have relatively low thermal stability at high temperature, low…

Evaluation of a Facial Animation Authoring Pipeline Seamlessly Supporting Performance Capture and Manual Key-pose Editing

Fabrizio Nunnari, Alexis Heloir

In this paper, we present an architecture following a novel animation authoring pipeline seamlessly supporting performance capture and manual editing of key-frames animation. This pipeline allows novice users to record and author sophisticated facial animations in a fraction of the time that would…

Human-Machine task allocation: Impact on patient safety in hospital settings, La distribution des tâches entre Homme et Machine : impact sur la sécurité des patients à l’hôpital

Sylvia Pelayo, Romaric Marcilly, Françoise Anceaux, Stéphanie Bernonville, Marie-Catherine Beuscart-Zephir

The paper aims at evaluating the impact of the tasks’ allocation between human and machine on the efficiency of work systems in the healthcare domain. Usability testing was performed to compare two different tasks’ allocations depending on two different systems (semi-automated system vs. manual…, Ce travail s’intéresse à l’impact de l’allocation des tâches entre humain et machine sur l’efficacité des systèmes de travail. Il défend l’idée que la conception d’outils doit être centrée sur l’humain et non pas orientée par la technique. Pour cela, on peut considérer l’humain et la machine comme…

Elasto-viscoplasticity Behaviour of a Structural Adhesive Under Compression Loadings at Low, Moderate and High Strain Rates

David Morin, Grégory Haugou, Franck Lauro, Bruno Bennani, Benjamin Bourel

Crashworthiness performance of automotives by introducing new materials is of high interest based on the global mass’ reduction of cars. Bonded techniques are tested at present with respect to the reduction of the mass/energy’s ratio combined with recycling processes. In this study, a compression…

A hybrid heuristic for the 0–1 Knapsack Sharing Problem

Boukthir Haddar, Mahdi Khemakhem, Said Hanafi, Christophe Wilbaut

The Knapsack Sharing Problem (KSP) is a variant of the well-known NP-hard knapsack problem that has received a lot of attention from the researches as it appears into several real-world problems such as allocating resources, reliability engineering, cloud computing, etc. In this paper, we propose a…
