Experimental and Numerical Investigations Using Lattice Boltzmann Method to Study Shedding Vortices in an Unsteady Confined Flow Around an Obstacle

Wafik Abassi, Fethi Aloui, Laurent Keirsbulck, Ben Nasrallah Sassi

Lattice Boltzmann equation with Bhatnagar–Gross–Krook (BGK) model is applied to simulate unsteady laminar flow around a confined square obstacle, in order to study the vortex shedding and their interaction in the flow on the mass transfer in the parietal zone of a channel. The model was tested by...

Numerical modeling of the low-velocity impact of composite plates using a shell-based SPH method

Jun Lin, Hakim Naceur, Daniel Coutellier, Serge Abrate

This paper investigates the numerical modeling of low velocity impact of composite multilayered plates using the smoothed particle hydrodynamics (SPH) method. Recently the authors developed a shell-based SPH (SSPH) model for the modeling of large deformations of composite multilayered structures,...

Multimodal depth and intensity face verification approach using LBP, SLF, BSIF, and LPQ local features fusion

Abdelmalik Ouamane, Abdelhamid Benakcha, Mebarka Belahcene, Abdelmalik Taleb-Ahmed

In this paper we present a robust multimodal depth and intensity face verification approach by the scores fusion of two multimodal systems (multi-algorithms: multiple descriptors fusion and multi-sensors: depth and intensity fusion). First, we correct the rotations of the head in all 3D by...

Improved principal component analysis for anomaly detection: Application to an emergency department

Fouzi Harrou, Farid Kadri, Sondès Chaabane, Christian Tahon, Ying Sun

Monitoring of production systems, such as those in hospitals, is primordial for ensuring the best management and maintenance desired product quality. Detection of emergent abnormalities allows preemptive actions that can prevent more serious consequences. Principal component analysis (PCA)-based...

Evaporation Experimental Study of Liquid Effluent after Methanation

Hiba Zouaghi, Souad Harmand, Sadok Ben Jabrallah

Pig manure rich in nitrogen, potassium and phosphorus was subjected to anaerobic digestion and phase separation via centrifugation. Several recovery scenarios for the liquid phase of a waste with 2.3% DM (Dry Matter) are analyzed in this paper. The physico-chemical characterization of the effluent...

Combination of cognitive and HCI modeling for the design of KDD-based DSS used in dynamic situations

Hela Ltifi, Christophe Kolski, Mounir Ben Ayed

Recent work in dynamic decision support systems (DSS) has taken impressive steps toward data preparation and storage, intelligent data mining techniques, and interactive visualization. However, it remains difficult to deal with the uncertainty and complexity generated by the Knowledge Discovery in...

Controller Design for Discrete-Time Descriptor Models: A Systematic LMI Approach

Víctor Estrada Manzo, Zsofia Lendek, Thierry-Marie Guerra, Philippe Pudlo

This paper provides a systematic way to generalize the controller design for discrete-time nonlinear descriptor models. The controller synthesis is done using a Takagi-Sugeno representation of the descriptor models and linear matrix inequalities. We propose approaches to exploit the discrete-time...

Simultaneous Estimation of Road Profile and Tire Road Friction for Automotive Vehicle

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort

The longitudinal motion control of automotive vehicles is heavily reliant on information about the time-varying tire road friction coefficient. In the presence of varying road roughness profiles, the effective vertical load on each wheel varies dynamically, influencing the tire friction. In this...

Consensus for linear multi-agent system with intermittent information transmissions using the time-scale theory

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper investigates the consensus problem for linear multi-agent system with fixed communication topology in the presence of intermittent communication using the time-scale theory. Since each agent can only obtain relative local information intermittently, the proposed consensus algorithm is...
