Towards a Building Techniques of a BREP Model Starting From a Meshed Surface

Nessrine Elloumi, Aicha Ben Makhlouf, Borhen Louhichi, Dominique Deneux

Abstract For several years, research has been brought to reconstruct a Computer Aided Design (CAD) model from a 3D mesh or point cloud produced by scanning techniques or CAD software. This process, which recreates the geometry of a real part is called Revere Engineering (RE). In the industry, RE…

Optimal Robust Model-Free Control for Altitude of a Mini-Drone Using PSO Algorithm

Hossam Eddine Glida, Latifa Abdou, Abdelghani Chelihi, Chouki Sentouh, Gabriele Perozzi

This paper presents a model-free controller based on particle swarm optimization algorithm (PSO-MFC) for the altitude systems of a Mini-Drone. A model-free control (MFC) is applied to improve both trajectory tracking and robustness of quadrotor in the presence of external uncertainties and…

Ankle dysfunction in multiple sclerosis and the effects on walking

Caroline Massot, Marc-Alexandre Guyot, Cécile Donze, Emilie Simoneau-Buessinger, Christophe Gillet, Sebastien Leteneur

Purpose: Even in the early stage of the disease, for patients suffering from multiple sclerosis (MS), the most common and reported biomechanical alterations in the lower limb are located at the ankle joint. However, the effects of these impairments on gait deterioration should be discussed.…

Elementary Numerical Analysis of Wet Foam Formation and Study of Its Flow Structures and Physical Behavior

Ebrahim Shirani, Sima Nasirzade, Fethi Aloui

Abstract The purpose of this study is to analyze the flow of wet foam and to study the effect of volume fraction, velocity and surface tension and other physical parameters on the foam flow. The most numerical researches done in this area are for single-phase flows. The numerical simulation in this…

Experimental Investigations on the Effect of a Wavy Surface on Hydrodynamic Instabilities in a Taylor-Couette System

Lamia Gaied, Emna Berrich, Marc Lippert, Laurent Keirsbulck, Fethi Aloui

Abstract In this work, we propose an experimental study of the effect of surface roughness of the internal cylinder Couette-Taylor system in order to investigate the hydrodynamic instabilities of the flow. During experiments, the inner cylinder, which presents a rough surface with u cylinder…

Numerical Investigating of Oscillatory Flow and Heat Transfer Through Stirling Regenerator

Houda Hachem, Ramla Gheith, Fethi Aloui

Abstract By developing our proper CFD code under Fortran, the performances of a Stirling engine are studied in unsteady laminar regime and closely linked to the properties of its regenerator. However, it is responsible about the maximum part of losses in the Stirling engine. These losses depend on…

Transient Rayleigh-Bénard Thermal Convection With Radiation Heat Transfer in Participating Media Using the Control Volume Finite Element Method (CVFEM) and Lattice Boltzmann Method

Raoudha Chaabane, Abdelmajid Jemni, Fethi Aloui

In this paper, a gas-kinetic Bhatnagar-Gross-Krook (BGK) model is constructed for the Rayleigh-Benard thermal convection transfer in a two-dimensional cavity containing an absorbing, emitting, and scattering medium, where the flow field and temperature field are described by two coupled Lattice…

Structural Analysis of Couette-Taylor Flow With Periodic Oscillation of the Inner Cylinder in Different Flow Regimes

Shima Mahmoudirad, Ebrahim Shirani, Fethi Aloui

Abstract The structures of flow in laminar Couette-Taylor flow with periodic oscillation of the inner cylinder rotation velocity (which linearly increases from zero to a fixed maximum value and then goes to zero again in each period) for different three regimes; Couette flow, Taylor vortex and wavy…

Robust Estimation for Nonlinear Continuous-Discrete Systems With Missing Outputs: Application to Automatic Train Control

Thierry-Marie Guerra, Braulio Norberto Aguiar Cota, Denis Berdjag, Bernard Demaya

This brief is about robust estimation for a sampled output system with continuous dynamics using unknown input observers (UIOs). A novel worst case estimation error bound is developed using a particular form of Gronwall inequality. The motivation is to assess the accuracy of the estimator in real-…

Stochastic home health care routing and scheduling problem with multiple synchronized services

Mohammed Bazirha, Abdeslam Kadrani, Rachid Benmansour

The home health care (HHC) covers a wide range of health care services carried out in patients’ home in case of illness, injury or aging. Each caregiver should as far as possible adhere to the schedule set by the decision maker. However, unforeseen events would sometimes occur and delay the…
