Toward real-time road detection for autonomous vehicles.

Yazid Lachachi, Mohamed Ouslim, Smail Niar, Abdelmalik Taleb-Ahmed

Road detection is a vital task for autonomous vehicles, as it has a direct link to passengers’ safety. Given its importance, researchers aimed to improve its accuracy and robustness. We look at the task from a holistic point of view, where we aim to balance computation and accuracy. A multimodal…

A non-triangular hub location problem

Jack Brimberg, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

Hub location problems generally assume that the triangle inequality applies on the edges of a complete graph. Hence the flow between any pair of nodes requires at most two hubs for the transfer process. Here we relax the triangle inequality restriction and present two new formulations of the…

Quantification of the Morphological Signature of Roping Based on Multiscale Analysis and Autocorrelation Function Description

Julie Marteau, Raphaël Deltombe, Maxence Bigerelle

Roping or ridging is a visual defect affecting the surface of ferritic stainless steels, assessed using visual inspection of the surfaces. The aim of this study was to quantify the morphological signature of roping to link roughness results with five levels of roping identified with visual…

Fuzzy Static Output Feedback Control for Path Following of Autonomous Vehicles With Transient Performance Improvements

Tran Anh-Tu Nguyen, Chouki Sentouh, Hui Zhang, Jean-Christophe Popieul

This paper provides a new solution for path following control of autonomous ground vehicles. H 2 control problem is considered to attenuate the effect of the road curvature disturbance. To this end, we formulate a standard model from the road-vehicle dynamics, the a priori knowledge on the road…

Muscular Maximal Strength Indices and Bone Variables in a Group of Elderly Women

Riad Nasr, N. Rassy, Eric Watelain, Joseph Matta, Fabienne Frenn, Maroun Rizkallah, Ghassan Maalouf, César El Khoury, Abdel Jalil Berro, Rawad El Hage

The aim of the present study was to explore the relations between muscular maximal strength indices and bone parameters (bone mineral density [BMD], hip geometry indices, and trabecular bone score [TBS]) in a group of elderly women. This study included 35 healthy elderly women whose ages range…

Micromechanical modeling of ductile fracture of human humerus

Jamila Rahmoun, Hakim Naceur, Pascal Drazetic, Christian Fontaine

This paper deals with the formulation, development and validation of a newly developed micromechanical-based model for the modeling of the nonlinear ductile fracture of human humerus. The originality of the present works concerns the coupling between the micromechanical formulation based on the…

A Decentralized Blockchain-Based Trust Management Protocol for the Internet of Things

Djamel Eddine Kouicem, Youcef Imine, Abdelmadjid Bouabdallah, Hicham Lakhlef

The Internet of Things (IoT) is a network that integrates a variety of heterogeneous nodes, such as connected devices (sensors, robots, and smart phones ...), connected cars, smart homes, etc. These smart objects communicate and collaborate in distributed and dynamic environments that are facing…

An energy-efficient scheduling and rescheduling method for production and logistics systems

Maroua Nouiri, Abdelghani Bekrar, Damien Trentesaux

Scheduling can be defined as the allocation of available resources over time while optimising a set of criteria like early completion time of task, holding inventory, etc. The complexity of the scheduling problem, already known to be high, increases if dynamic events and disruptions are considered…

Purchase intention-based agent for customer behaviours

Arnaud Doniec, Stéphane Lecoeuche, René Mandiau, Antoine Sylvain

Simulating human activities remains a challenging problem because the decision-making mechanisms underlying these activities are difficult to reproduce and mimic. In this article, we are interested in the simulation of in-store shoppers whose activities are generally divided into two parts: a…

The parking allocation problem for connected vehicles.

Marko Mladenovic, Thierry Delot, Gilbert Laporte, Christophe Wilbaut

In this paper, we propose a parking allocation model that takes into account the basic constraints and objectives of a problem where parking lots are assigned to vehicles. We assume vehicles are connected and can exchange information with a central intelligence. Vehicle arrival times can be…
