Cascade Descriptor Observers: Application to Understanding Sitting Control of Persons Living With Spinal Cord Injury

Hajer Srihi, Thierry-Marie Guerra, Tran Anh-Tu Nguyen, Philippe Pudlo, Antoine Dequidt

People with spinal cord injury (SCI) suffer from a drastic reduction in sitting stability which negatively impacts their postural control. Thus, sitting balance becomes one of the most challenging everyday exercises. To better understand the consequences of this pathology, we have to work with high...

Performance prediction for convolutional neural networks on edge GPUs

Halima Bouzidi, Hamza Ouarnoughi, Smail Niar, Abdessamad Ait El Cadi

Edge computing is increasingly used for Artificial Intelligence (AI) purposes to meet latency, privacy, and energy challenges. Convolutional Neural networks (CNN) are more frequently deployed on Edge devices for several applications. However, due to their constrained computing resources and energy...

Time-temperature superposition in viscoelasticity and viscoplasticity for thermoplastics

Vincent Dorleans, Rémi Delille, Delphine Notta-Cuvier, Franck Lauro, Éric Michau

The use of thermoplastics in the automotive industry is continuously increasing. Design of parts require the characterization and numerical modelling of thermo-mechanical behaviour of those materials under wide strain rate (0–300 s−1) and temperature ranges (−30 °C to +85 °C). Large and costly...

Analytical Model for the computation of the drug administration dynamics and inlet pressures of an intravenous infusion system

Mostafa Brik, Souad Harmand, Mony Girault, Anne-Laure Metz, François Rochiccioli, Fabrice Lapeyre, Jérome Clarysse

In this paper, we have elaborated an analytical model to study the dynamics of the Smof-Lipid delivery in Neonate nutrition fluid with an Intravenous (IV) infusion system. For a simple configuration, containing two inlets and one outlet, used mainly in neonatology, analytical computations were...

Computational Reduction of Optimal Hybrid Vehicle Energy Management

Carlos Armenta, Sebastien Delprat, Rudy R Negenborn, Ali Haseltalab, Jimmy Lauber, Michel Dambrine

Pontryagin's Minimum Principle is a way of solving hybrid powertrain optimal energy management. This letter presents an improvement of a classical implementation. The core of this improvement consists in relaxing the tolerance on some intermediate steps of the algorithm in order to reduce the...

Fabrication and optimization of high frequency ZnO transducers for both longitudinal and shear emission: application of viscosity measurement using ultrasound

Hatem Dahmani, Ibrahim Zaaroura, Abbas Salhab, Pierre Campistron, Julien Carlier, Malika Toubal, Souad Harmand, V. Thomy, Marc Neyens, Bertrand Nongaillard

This paper covers the study of high-frequency (~ 1 GHz) ZnO piezoelectric transducer integrated on a silicon substrate able to generate both compressional and shear acoustic waves. First, to promote the longitudinal mode, an electrical matching of the transducer in this high-frequency range is...

Spectral Analysis of LBM-LES Numerical Data on Lid-Driven Cavity

Insaf Mehrez, Ramla Gheith, Fethi Aloui

The lid-driven cavity is an important fluid mechanical system work for as a benchmark for testing numerical methods and for examining fundamental aspects of incompress- ible flows in confined volumes which are driven by the tangential motion of the bounding wall. A numerical study is provided of...

Theoretical Investigations of Stirling Engine Performances for Different Working Fluids

Houda Hachem, Ramla Gheith, Fethi Aloui

The present paper is performed to investigate the effect of working fluids on a double-acting Stirling engine performance. A numerical model that includes major thermal losses that decrease the Stirling output power and efficiency was developed. The influences of tree monatomic gases (helium, Neon...
