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…

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…

Dynamic evolution of interface roughness during friction and wear processes

K. J. Kubiak, Maxence Bigerelle, T. Mathia, André Dubois, Laurent Dubar

Dynamic evolution of surface roughness and influence of initial roughness (Sa = 0.282–6.73 µm) during friction and wear processes has been analyzed experimentally. The mirror polished and rough surfaces (28 samples in total) have been prepared by surface polishing on Ti–6Al–4V and AISI 1045 samples…

Ternary Zero Correlation Zone Sequence Sets for Asynchronous DS-CDMA

Benattou Fassi, Ali Djebbari, Abdelmalik Taleb-Ahmed

In this paper we propose a new class of ternary Zero Correlation Zone (ZCZ) sequence sets based on binary ZCZ sequence sets construction. It is shown that the proposed ternary ZCZ sequence sets can reach the upper bound on the ZCZ sequences. The performance of the proposed sequences set in…

Closed form solution for the collapse of polygonal thin-walled columns in the axial crushing case

Yamen Maalej, Fahmi Chaari, Bassem Zouari, Eric Markiewicz

The main objective of this paper is to propose a new closed form solution, useful in the pre-design stage, that allows one to calculate the mean load in the case of post-collapse of polygonal thin-walled columns in the axial crushing case. This model gives a rapid and accurate evolution of the…

L’aide à la décision comme cadre de gouvernance-innovation, Decision aiding as a framework of governance-innovation

Igor Crevits, Laurence Bonnafous, Said Hanafi

Dans cet article, nous avançons quelques arguments montrant que l’aide à la décision est utile pour soutenir une démarche d’innovation. Les concepts de l’aide à la décision permettent de caractériser finement une innovation, en la reliant à l’existant, comme une évolution et non comme une rupture.…, In this paper, we propose some arguments showing that decision aiding is useful for supporting an innovation approach. The concepts of decision aiding allow to finely characterize innovation, by linking it to the current situation, as an evolution rather than a disruption. The methodological…
