Building, sharing and exploiting spatio- temporal aggregates in vehicular networks

Dorsaf Zekri, Bruno Defude, Thierry Delot

This article focuses on data aggregation in vehicular ad hoc networks (VANETs). In such networks, data produced by sensors or crowdsourcers are exchanged between vehicles in order to warn or inform drivers when an event occurs (e.g., an accident, a traffic congestion, a parking space released, a…

Reflection on the Measurement and Use of the Topography of the Indentation Imprint

Julie Marteau, Maxence Bigerelle, Salima Bouvier, Alain Iost

The goal of this paper is to study the main uses of the residual imprint of the indentation test. It also discusses the different technologies and methods employed in this context. The difficulties encountered when trying to exploit the full potentials of the imprint are thoroughly examined. A…

Representation of the Agent Environment for Traffic Behavioral Simulation.

Feirouz Ksontini, Stéphane Espié, Zahia Guessoum, René Mandiau

The aim of this paper is to improve the validity of traffic simulations in (sub-)urban context, with a better consideration of driver behavior in terms of anticipation of positioning on the lanes and occupation of space. We introduce a model based on a multi-agent approach and the emergence concept…

Towards Qualitative and Quantitative Data Integration Approach for Enhancing HCI Quality Evaluation.

Ahlem Assila, Káthia Marçal de Oliveira, Houcine Ezzedine

Over the two past decades, various HCI quality evaluation methods have been proposed. Each one has its own strengths and its own shortcomings. Different methods are combined to enhance the evaluation results. To obtain better coverage of design problems and to increase the system performance,…

Adaptive Super-Twisting Observer for Estimation of Random Road Excitation Profile in Automotive Suspension Systems

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort

The estimation of road excitation profile is important for evaluation of vehicle stability and vehicle suspension performance for autonomous vehicle control systems. In this work, the nonlinear dynamics of the active automotive system that is excited by the unknown road excitation profile are…

A new local search for continuous location problems

Jack Brimberg, Zvi Drezner, Nenad Mladenovic, Said Salhi

This paper presents a new local search approach for solving continuous location problems. The main idea is to exploit the relation between the continuous model and its discrete counterpart. A local search is first conducted in the continuous space until a local optimum is reached. It then switches…

A novel multi-criteria decision making approach for personalisation system

Makram Soui, Khaled Ghedira, Mourad Abed

Personalised services is a field in rapid development. The aim of such system is to provide the user with relevant information that takes into consideration the context when using the system basing on the user preference learning. Today, these systems are indispensable to those who want to retrieve…

3D parameter to quantify the anisotropy measurement of periodic structures on rough surfaces

Gildas Guillemot, Maxence Bigerelle, Zahra Khawaja

In this paper, a new 3D roughness parameter, Sreg, is proposed to quantify the regularity of a surface, independent of the amplitude and the scanning length units of the surface. The efficiency of this parameter is tested on noisy periodical surfaces with degrees of anisotropy. This parameter lies…

Relevance of Roughness Parameters of Surface Finish in Precision Hard Turning

Nabil Jouini, Philippe Revel, Maxence Bigerelle

Precision hard turning is a process to improve the surface integrity of functional surfaces. Machining experiments are carried out on hardened AISI 52100 bearing steel under dry condition using c-BN cutting tools. A full factorial experimental design is used to characterize the effect of cutting…

On the Relation Between Surface Roughness of Metallic Substrates and Adhesion of Human Primary Bone Cells

Karine Anselme, Maxence Bigerelle

Surface characteristics of materials, whether their topography, chemistry, or surface energy, play an essential part in osteoblast adhesion on biomaterials. Thus, the quality of cell adhesion will influence the cell's capacity to proliferate and differentiate in contact with a biomaterial. We…
