Effect of 3D printed foot orthoses stiffness and design on foot kinematics and plantar pressures in healthy people

Gauthier Desmyttere, Sebastien Leteneur, Maryam Hajizadeh, Jacinte Bleau, Mickael Begon

Background Foot orthoses (FOs) have been widely prescribed to alter various lower limb disorders. FOs’ geometrical design and material properties have been shown to influence their impact on foot biomechanics. New technologies such as 3D printing provide the potential to produce custom shapes and...

Mathematical formulations for the parallel machine scheduling problem with a single server.

Abdelhak El Idrissi, Rachid Benmansour, Mohammed Benbrahim, David Duvivier

This paper addresses the problem of scheduling independent jobs on identical parallel machines with a single server to minimise the makespan. We propose mixed integer programming (MIP) formulations to solve this problem. Each formulation reflects a specific concept on how the decision variables are...

Leader-following consensus for multi-agent systems with nonlinear dynamics subject to additive bounded disturbances and asynchronously sampled outputs

Tomas Menard, Syed Ali Ajwad, Emmanuel Moulay, Patrick Coirault, Michael Defoort

This paper is concerned with the leader-following consensus problem for a class of Lipschitz nonlinear multi-agent systems with uncertain dynamics, where each agent only transmits its noisy output, at discrete instants and independently from its neighbors. The proposed consensus protocol is based...

Constrained Output-Feedback Control for Discrete-Time Fuzzy Systems With Local Nonlinear Models Subject to State and Input Constraints

Tran Anh-Tu Nguyen, Pedro Coutinho, Thierry-Marie Guerra, Reinaldo Martinez Palhares, Jun-Tao Pan

This article presents a new approach to design static output-feedback (SOF) controllers for constrained Takagi-Sugeno fuzzy systems with nonlinear consequents. The proposed SOF fuzzy control framework is established via the absolute stability theory with appropriate sector-bounded properties of the...

Strength and failure of an aluminum/PA66 self-piercing riveted assembly at low and moderate loading rates: Experiments and modeling

Nicolas Leconte, Benjamin Bourel, Franck Lauro, Claudiu Badulescu, Eric Markiewicz

The self piercing riveting (SPR) process is increasingly used in the automotive industry due to its ability to connect multi-materials for weight reduction considerations. The strength and failure of such multi-material assemblies need to be characterized and modelled for full-scale structural...

Behavior of the square-back Ahmed body global modes at low ground clearance

Baptiste Plumejeau, Laurent Keirsbulck, Sebastien Delprat, Marc Lippert, Wafik Abassi

The present work aims to study the evolution of the wake-flow dynamic, including the shear-layers interactions phenomena and the global modes behavior of a square-back Ahmed body with a width to height aspect ratio, w/h, of 1.346. Various ground-clearance configurations around the critical case...

Fracture rate dependency of an adhesive under dynamic loading

Noëlig Dagorn, Gérald Portemont, Vincent Joudon, Benjamin Bourel, Franck Lauro

Adhesive joints are widely developed in aeronautic and automotive design applications. When subjected to impact loading, the rate sensitivity of adhesively bonded joints becomes a subject of interest. In this study, the Mode I fracture behavior of an aeronautic adhesive is characterized. Double...

Predicting manual wheelchair initiation movement with EMG activity during over ground propulsion

Soufien Chikh, Samuel Boudet, Antonio Pinti, Cyril Garnier, Rawad El Hage, Fairouz Azaiez, Eric Watelain

Context/Objective: This is a preliminary study of movement finalities prediction in manual wheelchairs (MWCs) from electromyography (EMG) data. MWC users suffer from musculoskeletal disorders and need assistance while moving. The purpose of this work is to predict the direction and speed of...

Effect of sensory stimulation applied under the great toe on postural ability in patients with fibromyalgia

Frédéric Viseux, Daniel Martins, Philippe Villeneuve, Pascal Charpentier, Leandra de Sant’anna E Silva, Afonso Salgado, Antoine Lemaire

Fibromyalgia (FM) is a chronic pain syndrome, characterised by several symptoms. One of the most prevalent symptoms in FM is balance impairment that compromise the autonomy, function and performance status of patients. Purpose: The main objective of the present study was to evaluate the effect of...

Toward real-time road detection for autonomous vehicles.

Yazid Lachachi, Mohamed Ouslim, Smail Niar, Abdelmalik Taleb-Ahmed

Road detection is a vital task for autonomous vehicles, as it has a direct link to passengers’ safety. Given its importance, researchers aimed to improve its accuracy and robustness. We look at the task from a holistic point of view, where we aim to balance computation and accuracy. A multimodal...
