Hierarchical Decomposition Thermodynamic Approach for the Study of Solar Absorption Refrigerator Performance

Emma Berrich Betouche, Ali Fellah, Ammar Ben Brahim, Fethi Aloui, Michel Feidt

A thermodynamic approach based on the hierarchical decomposition which is usually used in mechanical structure engineering is proposed. The methodology is applied to an absorption refrigeration cycle. Thus, a thermodynamic analysis of the performances on solar absorption refrigerators is presented…

Analysis of the effects of different machining processes on sealing using multiscale topography

Raphaël Deltombe, Maxence Bigerelle, Abdeljalil Jourani

This study characterizes seal performance using a multiscale analysis of surface topography. The performance of two surface morphologies is compared: the first one is obtained with machining only and leads to leakage while the second one is obtained with machining and superfinishing and prevents…

Generalized LMI observer design for discrete-time nonlinear descriptor models

Víctor Estrada Manzo, Zsofia Lendek, Thierry-Marie Guerra

The present paper provides a systematic way to generalize Takagi-Sugeno observer design for discrete-time nonlinear descriptor models. The approach is based on Finsler's lemma, which decouples the observer gains from the Lyapunov function. The results are expressed as strict LMI constraints.…

Binary Control Design for a Class of Bilinear Systems: Application to a Multilevel Power Converter

Laurentiu Hetel, Michael Defoort, Mohamed Djemai

This brief studies the local stabilization of bilinear systems with binary inputs. A novel convex optimization procedure for the robust design of switching surfaces is proposed using convex optimization tools and linear matrix inequalities. The procedure takes into account the robustness to…

A new approach of the Star Excursion Balance Test to assess dynamic postural control in people complaining from chronic ankle instability

Raphaël Pionnier, Nicolas Decoufour, Franck Barbier, Christophe Popineau, Emilie Simoneau-Buessinger

The purpose of this study was to quantitatively and qualitatively assess dynamic balance with accuracy in individuals with chronic ankle instability (CAI). To this aim, a motion capture system was used while participants performed the Star Excursion Balance Test (SEBT). Reached distances for the 8…

The Stroop and Reverse Stroop Effects as Measured by an Interactive Tabletop

Holly C Miller, Sébastien Kubicki, Delphine Caffier, Christophe Kolski, Janick Naveteur

An interactive tabletop equipped with RFID technology implemented the Stroop and reverse-Stroop tasks. Participants moved a tangible object into one of four displayed virtual zones, which were identified either by a color border or the name of a color written in black. The correct target zone…

Role of frozen lubricant film on tribological behaviour and wear mechanisms in grinding

Eduardo Garcia, Damien Méresse, Iñigo Pombo, Mirentxu Dubar, José Antonio Sánchez

In this paper the friction conditions of Minimum Coolant Grinding (MCG) technology are deeply characterized. The MCG is a successful cooling/lubricating system that combines the application of Minimum Quantity of Lubrication (MQL) and CO2 at low temperatures to create a frozen layer of oil able to…

Dynamic behaviour of honeycombs under mixed shear-compression loading: Experiments and analysis of combined effects of loading angle and cells in-plane orientation

Rami Tounsi, Eric Markiewicz, Grégory Haugou, Fahmi Chaari, Bassem Zouari

Cellular materials such as aluminium honeycombs combine lightweight challenges with high mechanical performance for crash energy absorption regulations. This paper investigates experimentally the dynamic behaviour of an aluminium alloy honeycomb under mixed shear-compression loading with a special…

Nonquadratic Controller and Observer Design for Continuous TS Models: A Discrete-Inspired Solution

Temoatzin González, Raymundo Márquez Borbόn, Miguel Bernal, Thierry-Marie Guerra

This work deals with controller and observer design for continuous-time Takagi–Sugeno models based on a new nonquadratic Lyapunov function. The proposed technique intends to attain the level of development reached by its discrete-time counterpart by suitably adapting one of its key ideas: the…
