Folk-IS : Opportunistic Data Services in Least Developed Countries

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leila Kloul, Nathalie Mitton, Philippe Pucheral

According to a wide range of studies, IT should become a key facilitator in establishing primary education, reducing mortality and supporting commercial initiatives in Least Developed Countries (LDCs). The main barrier to the development of IT services in these regions is not only the lack of...

The resonance/thickness prediction of an ultra-thin layer by the low-frequency ultrasound

Gui-Jin Yao, Wei-Jiang Xu, Ke-Xie Wang

A prediction method of the thickness, resonant space and frequency for the two cases of an ultra-thin layer and the narrow-band frequency spectra has been developed without the appearance of the resonance/anti-resonance. Using the characteristic of straight line and the period of π of the layer...

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...

Participatory Design of a Cooperative Exploration Mediation Tool for Human Deep Space Risk Mitigation

Donald Platt, Patrick Millot, Guy Andre Boy

This work describes the participatory design and development of a Virtual Camera (VC) system to improve astronaut and mission operations exploration efficiency and cooperation while exploring in deep space. Advanced interaction media capabilities can improve exploration efficiency and cooperation...

To pass or not to pass: More a question of body orientation than visual cues

Aurore Bourrelly, J-L Vercher, L. Bringoux

This study investigated the influence of pitch body tilt on judging the possibility of passing under high obstacles in the presence of an illusory horizontal self-motion. Seated subjects tilted at various body orientations were asked to estimate the possibility of passing under a projected bar (i.e...

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...

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...

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...
