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…

Galling phenomena in metal forming

Kuniaki Dohda, Masahito Yamamoto, Chengliang Hu, Laurent Dubar, Kornel F. Ehmann

Galling phenomena in metal forming not only affect the quality of the engineered surfaces but also the success or failure of the manufacturing operation itself. This paper reviews the different galling conditions in sheet and bulk metal forming processes along with their evolution and the effects…

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…

Non-Binary Parallel Turbo LDPC Codes Associated with High Order Constellation

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Since the non-binary LDPC (Low-Density Parity-Check) codes offer better performance than binary LDPC codes for a system using high order constellations such as the QAM (Quadrature Amplitude Modulation), one proposes in this paper a high non-binary LDPC code, called a parallel nonbinary turbo LDPC…

#Coronamaisons : confinement sur les réseaux sociaux

Caroline Soreau

Mars 2020. La France se confine. Le monde extérieur semble s’arrêter ; le temps ralentir considérablement. Nous devons rester chez nous ; sauver le monde depuis notre canapé. Drôle de guerre. Le bouleversement de notre quotidien provoque l’inquiétude, l’angoisse, voire la paranoïa. Parallèlement,…, March 2020. France is on lockdown. The outside world seems to stop ; time is slowing down considerably. We must stay at home ; save the world from our couch. Phony War. The upheaval in our daily lives causes worry, anguish and even paranoia. At the same time, we are observing a real burst of…

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…

Heating Rate Effect on Tetrapak Paper Pyrolysis: Thermogravimetric Analysis

Afef Bouazizi, Emna Berrich, Imene Bekri, Ezzedine Srasra, Fethi Aloui

Biomass and plastics are considered to be one of the most important renewable sources in nature. The typical composition of a tetrapak is 70% of cardboard (Kraft paper), 25% of low-density polyethylene (LDPE), and 5% of aluminum foil. In this paper, we present the heat rate effect on tetrapak…

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…
