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…

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…

Capability Assessment of Five Different RANS-Based Turbulence Models to Simulate the Various Regions of Slot Turbulent Impingement Jet Flow

Mahmoud Charmiyan, Ahmed-Reza Azimian, Ebrahim Shirani, Fethi Aloui

In this paper, impingement of a turbulent rectangular flow to a fixed wall is investigated. The jet flows from bottom-to-top and the output jet Reynolds is 16000. The nozzle-to-plate distance is equal to 10 (H/e = 10). Five turbulence models, including k-ε, RNG k-ε, k-ω SST, RSM and v2f model have…

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…

A uniform formalism for acoustic wave propagation in a mixed liquid-solid-porous viscoelastic multilayered structure

Sandrine Matta, Wei-Jiang Xu, Georges Nassar, Antoine Abche

To deepen the understanding of the ultrasonic behaviour of human multi-layered bone tissues, cortical bone for example, the reflection and transmission of ultrasonic wave at such a structure consisting of a combination of liquid-solid-porous layers was studied. A mathematical model for the plane…

Fuel production from thermoplastic wastes pyrolysis

Emna Berrich, 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…

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.…

An Extrinsic Sensor Calibration Framework for Sensor-fusion based Autonomous Vehicle Perception

Mokhtar Bouain, Denis Berdjag, Nizar Fakhfakh, Rabie Ben Atitallah

In this paper we deal with sensor alignment problems that appear when implementing sensor fusion-based autonomous vehicle perception. We focus on extrinsic calibration of vision-based and line scan LIDAR sensors. Based on state-of-art solutions, a consistent calibration toolchain is developed, with…
