Dynamics of the recirculating areas of a forward-facing step

Anthony Graziani, Franck Kerhervé, Robert J. Martinuzzi, Laurent Keirsbulck

The dynamics of the velocity and surface pressure fields in the recirculating regions upstream of the foot of a forward-facing step and downstream of the step corner are investigated experimentally for a thin turbulent oncoming boundary layer at a Reynolds number, based on the step height, of 105.…

Experimental Study of the Liquid/Vapor Phase Change in a Porous Media of Two-Phase Heat Transfer Devices

Riadh Boubaker, Souad Harmand, Vincent Platel

The study presents an experimental examination of heat and mass transfer with phase change in a porous media composed of copper foam. The aim of the study involves separately examining the effect of the adverse hydrostatic head, subcooling at the wick inlet and wick properties (porosity and average…

From MDD to BDD and Arc consistency

Julien Vion, Sylvain Piechowiak

In this paper, we present a new conversion of multivalued decision diagrams (MDD) to binary decision diagrams (BDD) which can be used to improve MDD-based fil- tering algorithms such as MDDC or MDD-4R. We also propose BDDF, an algorithm that copies modified parts of the BDD “on the fly” during the…

Whale optimization algorithm based optimal reactive power dispatch: A case study of the Algerian power system

Khaled Ben Oualid Medani, Samir Sayah, Abdelghani Bekrar

Optimal reactive power dispatch (ORPD) is a particular case of the optimal power flow. ORPD was usually considered as the minimization of an objective function representing the total active power losses in the electrical networks. The constraints involved are the generator voltages, tap regulating…

Power optimization techniques for associative processors

Hasan Erdem Yantir, Ahmed Eltawil, Smail Niar, Fadi Kurdahi

The toughness and complexity of the computational problems which human beings tackle rise faster than the computational platforms themselves. Moreover, the dark silicon era negatively effects the traditional computational platforms and contributes unfavorably to this gap. These situations require…

Helping older pedestrians navigate unknown environments through vibrotactile guidance instructions

Stéphanie Coeugnet, Aurélie Dommes, Sabrina Paneels, Fabrice Vienne, Nguyen-Thong Dang, Margarita Anastassova, Laure Léger, Aline Chevalier

Many studies have consistently found evidence of aging-related navigation difficulties that lead to disorientation behaviors and/or reduced travel. Despite technological advances, older pedestrians mainly use paper maps to find their way in unknown environments while they have a lot of difficulties…

Behind armour blunt trauma assessment by means of experimental and numerical approaches

Anthony Bracq, Rémi Delille, Benjamin Bourel, Christophe Maréchal, Grégory Haugou, Franck Lauro, Sébastien Roth, Olivier Mauzac

The risk of Behind Armour Blunt Trauma (BABT) has become a primary concern for the law enforcement officers, soldiers and armour manufacturers. Indeed, the need for body armour weight reduction and the enhancement of projectile efficiency may result in a higher body armour deformation and therefore…

Speech enhancement using Rao–Blackwellized particle filtering of complex DFT coefficients

Mounir Meddah, Abderrahmane Amrouche, Abdelmalik Taleb-Ahmed

An improved method for speech enhancement, which is based on particle filtering, is presented in this paper. The Rao–Blackwellized particle filter (RBPF) is used to estimate the model parameters and recover a clean speech signal. The proposed method (named DFT-RBPF) enhances the complex discrete…

Approximation Algorithm for 3-Dimensional Vehicle Routing Problem for Fleet of Multi-Agents

Setyawan Ajie Sukarno, Rabie Ben Atitallah, Mohamed Djemai

In this paper, we discuss a 3-Dimensional Vehicle Routing Problem (VRP) for a fleet of multi-agents which doing a surveillance mission above a certain terrain. The fleet must performs routes to visit a set of points while respecting constraints. Since VRP is classified as an NP-hard optimization…
