Experimental study of the strain rate dependence of a synthetic gel for ballistic blunt trauma assessment

Anthony Bracq, Grégory Haugou, Rémi Delille, Franck Lauro, Sébastien Roth, Olivier Mauzac

The mechanical characterization of a polymer gel used as reference backing material for blunt ballistic impact interpretation is performed at room temperature from quasi-static (0.002 s−1) up to high strain rates (1500 s−1). As very high strain tensile tests (350%) are conducted, an appropriate…

Solving the clique partitioning problem as a maximally diverse grouping problem

Jack Brimberg, Stefana Janićijević, Nenad Mladenovic, Dragan Urošević

In this paper we show that the clique partitioning problem can be reformulated in an equivalent form as the maximally diverse grouping problem (MDGP). We then modify a skewed general variable neighborhood search (SGVNS) heuristic that was first developed to solve the MDGP. Similarly as with the…

Fuel Production From Plastic Wastes Pyrolysis

Emma Berrich Betouche, Asma Dhahak, Abdelaziz Touati, Fethi Aloui

Energetic valorization of thermoplastic wastes (High-density polyethylene (PE) and Polypropylene (PP)) to produce fuel using pyrolysis process is presented in this paper. HDPE and PP pyrolysis experiments were carried out in a lab-scale batch reactor under an inert atmosphere. Nitrogen gas was used…

Experimental Study on the Effects of Surface Roughness on the Behaviors of Hydrodynamic Instabilities of Couette-Taylor Flow

Mostafa Monfared, Lamia Gaied, Emna Berrich, Ebrahim Shirani, Maxence Bigerelle, Fethi Aloui

Couette-Taylor flow is a type of fluid flow that occurs in the annulus between differentially concentric cylinders, when the outer cylinder is fixed and the inner cylinder rotates and the rotation rate exceeds a critical value. In this research we have studied the effect of surface roughness on the…

Particles Transport in Railway Braking Systems: An Experimental and Numerical Investigation

Charlène Octau, Marc Lippert, Anthony Graziani, Michel Watremez, Laurent Keirsbulck, Laurent Dubar, Talib Dbouk

There has been a growing public health issue concerning the regulation of indoor air quality (IAQ) and the human exposure to particulate matter (PM). Today, this exposure is a major worldwide concern because ambient PM concentrations in many cities exceeded the limits set by the European air…

Machine learning control for experimental turbulent flow targeting the reduction of a recirculation bubble

Camila Chovet, Marc Lippert, Laurent Keirsbulck, Bernd R. Noack, Jean-Marc Foucaut

We experimentally control the turbulent flow over backward-facing step (Re H = 31500). The goal is to modify the internal (Xr) and external (Lr) recirculation points and consequently the recirculation zone (Ar). A model-free machine learning control (MLC) is used as control logic. As benchmark, an…

Entropy Generation for Oscillatory Flow Inside Thermal-Lag Type Stirling Engine: Numerical Analysis

Houda Hachem, Ramla Gheith, Sassi Ben Nasrallah, Fethi Aloui

The present paper investigates the heat characteristics of oscillatory piston-driven flow inside thermal-lag type Stirling engine. The geometry consists of a cylinder partially filled with a porous metal structure called regenerator, heated at the lateral wall on one side and cooled on the other…

Comparing multiple correspondence and principal component analyses with biomechanical signals. Example with turning the steering wheel

Pierre Loslever, Jessica Schiro, François Gabrielli, Philippe Pudlo

The purpose of this article is to compare Principal Component Analysis (PCA) and a much less used method, i.e. MCA (Multiple Correspondence Analysis) with data being first changed into membership values to fuzzy space windows. For such a comparison, data from an experimental study about turning the…

Unknown input observer in descriptor form via LMIs for power-assisted wheelchairs

Guoxi Feng, Thierry-Marie Guerra, Lucian Busoniu, Sami Mohammad

Power-assisted wheelchairs (PAW) provide an efficient means of transport for disabled persons. In this human-machine interaction, the human-applied torque is a crucial variable to implement the assistive system. The present paper describes a novel scheme to design PAWs without torque sensors.…
