How we perceive our own hands: Effects of attention, aging, and sex

Janick Naveteur, Marie-Agnes Dupuy, François Gabrielli, George A. Michael

This study investigates whether both the perception of somesthetic sensations arising spontaneously on the hand and their modulation by attention are subject to change with advancing age and sex. Participants aged between 50 and 68 (N = 24), and younger (19–27; N = 24), with an equal sex ratio in…

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…

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…

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…

R-peaks detection based on stationary wavelet transform

Mostefa Merah, Abdelmalik Taleb-Ahmed, Hadj Larbi Beklaouz

Automatic detection of the QRS complexes/R-peaks in an electrocardiogram (ECG) signal is the most important step preceding any kind of ECG processing and analysis. The performance of these systems heavily relies on the accuracy of the QRS detector. The objective of present work is to drive a new…

New heuristic algorithms for solving the planar p-median problem

Zvi Drezner, Jack Brimberg, Nenad Mladenovic, Said Salhi

In this paper we propose effective heuristics for the solution of the planar p-median problem. We develop a new distribution based variable neighborhood search and a new genetic algorithm, and also test a hybrid algorithm that combines these two approaches. The best results were obtained by the…

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…

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…

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,…

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…
