Experimental Droplet Study of Inverted Marangoni Effect of a Binary Liquid Mixture on a Nonuniform Heated Substrate

Safouene Ouenzerfi, Souad Harmand

We present an experimental study on the inversion of the Marangoni effect of a binary mixture droplet under a horizontal temperature gradient. In particular, we studied the dynamics and the evaporation behavior under these conditions. We show that a binary mixture (97% water–3% butanol) droplet has...

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...

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...

Power Cycling Reliability of Power Module: A Survey

Camille Durand, Markus Klingler, Daniel Coutellier, Hakim Naceur

Electronic devices using semiconductors such as insulated-gate bipolar transistors, metal-oxide-semiconductor field-effect transistors, and diodes are extensively used in electrical traction applications such as locomotive, elevators, subways, and cars. The long-term reliability of such power...

Impact of natural variability of flax fibres properties on mechanical behaviour of short-flax-fibre-reinforced polypropylene

Delphine Notta-Cuvier, Franck Lauro, Bruno Bennani, Mariem Nciri

Short-flax-fibre-composite materials are appealing for technical applications thanks to renewability, biodegradability but also potentially high ratio rigidity/density of flax fibres, in particular. However, the significant variability of technical flax fibres’ constitutive, geometrical and...

A non-quadratic Lyapunov functional for H∞ control of nonlinear systems via Takagi–Sugeno models

Raymundo Márquez Borbόn, Thierry-Marie Guerra, Miguel Bernal, Alexandre Kruszewski

This paper presents a novel non-quadratic Lyapunov functional with time delay for controller design and H∞ disturbance rejection for nonlinear systems. Based on an exact Takagi–Sugeno representation of the nonlinear model, a proper integral structure for Lyapunov-based design allows circumventing...

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...

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....

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...
