Upper limb contribution during tandem gait in multiple sclerosis: An early marker of balance impairments

Caroline Massot, Nicolas Decoufour, Mathias Blandeau, Franck Barbier, Cécile Donze, Emilie Simoneau, Sébastien Leteneur

Tandem gait is widely used during clinical exams to evaluate dynamic balance in chronic diseases, such as multiple sclerosis (MS). The early detection of balance impairments in MS is challenging to improve the understanding of patients’ complaints. The objective was to propose two indexes to…

Drag mitigation by steady blowing and Coanda effect on a square back Ahmed body

Baptiste Plumejeau, Laurent Keirsbulck, Jérémy Basley, Marc Lippert, Sébastien Delprat, Wafik Abassi

The impact of converging steady blowing on the global drag past a square back Ahmed bluff body is investigated experimentally. The dynamics of the recirculation bubble are studied for a width to height aspect ratio, w/h of 1.346, with a ground clearance of g/w = 0.154, and for a nominal Reynolds…

Centralized Collaborative Planning of an Industrial Symbiosis: Mixed-integer linear model

Cécilia Daquin, Hamid Allaoui, Gilles Goncalves, Tienté Hsu

Nowadays production, distribution and consumption modes disrupt ecosystems. In order to preserve the environment, Circular Economy (CE) proposes to reduce the environmental footprint in a social approach. Among the principles of CE, Industrial Ecology seeks to limit the impact of industries on the…

Pain and Parkinson's disease: current mechanism and management updates.

Frederic J. F. Viseux, Arnaud Delval, Martin Simoneau, Luc Defebvre

The aim of this comprehensive review was to provide an overview of pain in Parkinson's disease (PD) by identifying different clinical features and potential mechanisms, and presenting some data on the evaluation and management of pain in PD. PD is a multifocal degenerative and progressive…

A blockchain-based framework for circular end-of-life vehicle processing

Rima Grati, Faiza Loukil, Khouloud Boukadi, Mourad Abed

The transition of the automotive industry to a circular economy (CE) is related to the significant environmental and social impacts of its products, which are resource-intensive in terms of materials and energy, both in the production and usage phases, as well as in their end-of-life. A blockchain…

Experimental assessment on the performance, emission and combustion characteristics of a safflower oil fueled CI engine with hydrogen gas enrichment

V. Praveena, Femilda Josephin Joseph Shobana Bai, Dhinesh Balasubramanian, Yuvarajan Devarajan, Fethi Aloui, Edwin Geo Varuvel

Inducting hydrogen with biodiesel in a compression ignition (CI) engine contributes to improvising the performance characteristics of the engine and minimize long-term issues. Combustion of hydrogen along with intake air impacts positively in air quality by preventing the formation of toxic…

Distributed Predefined-Time Optimization for Second-Order Systems under Detail-Balanced Graphs

Pablo de Villeros, Juan Diego Sánchez-Torres, Aldo Jonathan Muñoz-Vázquez, Michael Defoort, Guillermo Fernández-Anaya, Alexander Loukianov

This paper studies the problem of distributed predefined-time optimization for leaderless consensus of second-order multi-agent systems under a class of weighted digraphs. The proposed framework has two main steps. In the first step, the agents communicate to perform a consensus-based distributed…

Multi-scale mechanical characterization of the interface in 3D printed concrete

M. Taleb, D. Bulteel, Damien Betrancourt, Francine Roudet, S. Rémond, A. Montagne, Didier Chicot

To be printable, the cementitious ink may have contradictory properties. It must be fluid enough initially to be pumpable and extrudable, also should stiffen quickly after deposition to be buildable. This could be influential, along with other printing parameters, on its interlayer zone. Thus, the…

Characterization of local mechanical properties of Al/Cu Magnetic Pulse Welded joints under high strain rates using synchrotron X-ray imaging, Caractérisation locale des propriétés mécanique de soudures Al/Cu produites par Soudage par Impulsion Magnétique sous haute-vitesses de déformation et imagerie à rayons-X synchrotron

Benjamin Zielinski, Tarik Sadat, Bratislav Lukić, Grégory Haugou, Hervé Morvan, Alexander Rack, Eric Markiewicz, Laurent Dubar

Magnetic Pulse Welding (MPW) is a method of growing interest allowing the joining of dissimilar materials such as aluminum and copper. The global mechanical properties of the joint are often evaluated with conventional tests, using the fully welded joint. However, these cannot elucidate the local…, Le Soudage par Impulsion Magnétique (SIM) est une méthode dont l'intérêt est croissant permet de joindre des matériaux dissimilaires tels que l'aluminium et le cuivre. Les propriétés mécaniques globales des soudures sont souvent évaluées au travers de tests conventionnels, en utilisant le…

Sensorimotor Time Delay Estimation by EMG Signal Processing in People Living with Spinal Cord Injury

Seyed Mohammadreza Shokouhyan, Mathias Blandeau, Laura Wallard, Thierry Marie Guerra, Philippe Pudlo, Dany H Gagnon, Franck Barbier

Neuro mechanical time delay is inevitable in the sensorimotor control of the body due to sensory, transmission, signal processing and muscle activation delays. In essence, time delay reduces stabilization efficiency, leading to system instability (e.g., falls). For this reason, estimation of time…
