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…

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…

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…

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…

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…

Identification of heat partition in grinding related to process parameters, using the inverse heat flux conduction model

Eduardo García, Damien Méresse, Iñigo Pombo, Souad Harmand, José Antonio Sánchez

Grinding is an abrasive machining process characterized by producing high quality components for high added-value industries. Thermal damage is an undesired phenomenon that may ruin nearly finished products. The study of thermal damage requires understanding the mechanisms of heat partition between…

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…

Sliding subspace design based on linear matrix inequalities

Alan Tapia, Raymundo Márquez Borbόn, Miguel Bernal, Joaquín Cortez

In this work, an alternative for sliding surface design based on linear and bilinear matrix inequalities is proposed. The methodology applies for reduced and integral sliding mode control, both continuous- and discrete-time; it takes advantage of the Finsler's lemma to provide a greater degree…

Lighter tableware ceramic by controlling porosity: Effect of porosity on mechanical properties

Benjamin Verhaeghe, Christian Courtois, F. Petit, F. Cambier, Jean-Dominique Guerin, Anne Leriche, Stuart Hampshire

Reduction in weight of ceramics has been achieved by using a specific porous agent, starch, to achieve porosity ranging from 10% to 35%. Two incorporation routes of the porous agent have been investigated. For different levels of weight reduction, ceramics are characterized by microstructural…
