Towards a framework for ontology-based information retrieval services

Amir Zidi, Mourad Abed

In this paper, we present a complete ontology-based framework for the extraction and retrieval of semantic information in specific domains. We focus on the recognition of semantic information extracted from data sources and the mapping of this knowledge into ontology. In order to achieve more…

Influence of swabbing compounds on loading, heat transfer and release performance in hot glass forming

Philippe Moreau, Dominique Lochegnies, Hugues Vivier

In the glass container manufacturing industry, hot moulds are regularly swabbed with a lubricant during production. The swabbing lubricant facilitates the loading of glass into a mould, reduces heat exchange when the glass comes into contact with the mould and expedites the release of the glass…

Constitutive description for the design of hot-working operations of a 20MnCr5 steel grade

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Mirentxu Dubar, Mariana H. Staia, Jacky Lesage, Didier Chicot

The development of sound constitutive descriptions able to predict accurately the changes in flow stress during plastic deformation, under changing temperature and strain rate conditions is of utmost importance for the correct prediction of the mechanical response of metals and alloys, which…

Analysis from robust control under environment constraint: application for traffic model

Milka Uzunova, Mohamed Djemai

Traffic management solutions are increasingly called for to address problems of transport and mobility and nowadays, even to address the environmental impact. Traffic control uses strategies to reduce bottlenecks, travel time and costs. Although it is usually assumed that an improved traffic flow…

The influence of speaker gaze on listener comprehension: Contrasting visual versus intentional accounts

Maria Staudte, Matthew W. Crocker, Alexis Heloir, Michael Kipp

Previous research has shown that listeners follow speaker gaze to mentioned objects in a shared environment to ground referring expressions, both for human and robot speakers. What is less clear is whether the benefit of speaker gaze is due to the inference of referential intentions (Staudte and…

Composition of Wide Bandgap Semiconductor Materials and Nanostructures Measured by Atom Probe Tomography and Its Dependence on the Surface Electric Field

Lorenzo Mancini, Nooshin Amirifar, Deodatta Shinde, Ivan Blum, Matthieu Gilbert, Angela Vella, François Vurpillot, Williams Lefebvre, Rodrigue Lardé, Etienne Talbot, Philippe Pareige, Xavier Portier, Ahmed Ziani, Christian Davesnne, Christophe Durand, Joël Eymery, Raphaël Butté, Jean-François Carlin, Nicolas Grandjean, Lorenzo Rigutti

Atom probe tomography allows for three-dimensional reconstruction of the elemental distribution in materials at the nanoscale. However, the measurement of the chemical composition of compound semiconductors may exhibit strong biases depending on the experimental parameters used. This article…

Nonquadratic Lyapunov function for continuous TS fuzzy models through their discretization

Ameni Ellouze, François Delmotte, Jimmy Lauber, Mohamed Chtourou, Mohamed Ksantini

Since the beginning of the fuzzy control theory, results have been obtained independently for continuous and discrete models. It is still quite difficult to use nonquadratic Lyapunov functions for the continuous case, while this is much easier for the discrete case. This approach tries to put a…

Wetting of anisotropic sinusoidal surfaces—experimental and numerical study of directional spreading

Fisher Guillaume, Maxence Bigerelle, Krzysztof Kubiak, T.G. Mathia, Z. Khatir, Karine Anselme

Directional wettability, i.e. the variation of wetting properties, depending on the surface orientation, can be achieved by anisotropic surface texturing. A new high-precision process can produce homogeneous sinusoidal surfaces (in particular, parallel grooves) at the microscale, with a nanoscale…

An Experimental and Numerical Study on the Effects of the Flat Heat Pipe Wick Structure on Its Thermal Performance

Hamdy Hassan, Souad Harmand

This paper presents an experimental and numerical work on the effect of flat heat pipe construction on the cooling of an electronic component. The flat heat pipe is heated via 1-cm-diameter circular electrical resistance (the evaporator side), and the other side (the condenser side) is cooled by…

Roughness characterization of the galling of metals

Cédric Hubert, Julie Marteau, Raphaël Deltombe, Y Chen, Maxence Bigerelle

Several kinds of tests exist to characterize the galling of metals, such as that specified in ASTM Standard G98. While the testing procedure is accurate and robust, the analysis of the specimenʼs surfaces (${\rm area}=1.2\;{\rm cm}$) for the determination of the critical pressure of galling remains…
