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…

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…

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,…

Communication System for Persons with Cerebral Palsy In Situ Observation of Social Interaction Following Assisted Information Request

Yohan Guerrier, Janick Naveteur, Christophe Kolski, Franck Poirier

People with disabilities may encounter many communication difficulties. Our main goal is to develop a communication system, called COMMOB, designed to assist people with cerebral palsy in different contexts: at home, at work and in public places. After a brief review of the different categories of…

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…

Fracture mechanics in new designed power module under thermo‐mechanical loads

Camille Durand, Markus Klingler, Daniel Coutellier, Hakim Naceur, Arian Grams, Olaf Wittler

Thermo-mechanically induced failure is a major reliability issue in the microelectronic industry. On this account, a new type of Assembly Interconnected Technology used to connect MOSFETs in power modules has been developed. The reliability is increased by using a copper clip soldered on the top…

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…

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…
