A class of predefined-time controllers for uncertain second-order systems

Juan Diego Sanchez-Torres, Aldo-Jonathan Muñoz-Vázquez, Michael Defoort, Esteban Jiménez-Rodríguez, Alexander Loukianov

This paper proposes a novel formulation for robust predefined-time stabilisation of a class of second-order systems with matched perturbations. The presented approach allows designing a family of controllers that enforce a predefined-time sliding motion, even in the presence of unknown but bounded…

Numerical study of flow around two spheres filled by a phase-change material

Fatma Ghrissi, Belgacem Dhifaoui, Souad Harmand, Sadok Ben Jabrallah

A numerical simulation using the commercial software “COMSOL Multiphysics” was carried out to study the flow around two fixed spheres filled with a phase-change material (PCM). This work focuses essentially on the process of fusion of the two interactive spheres located at different distances and…

Mechanistic insights on ultra-tough polylactide-based ionic nanocomposites

Jean-Emile Potaufeux, Jérémy Odent, Delphine Notta-Cuvier, Rémi Delille, Sophie Barrau, Emmanuel P. Giannelis, Franck Lauro, Jean-Marie Raquez

We report the synthesis and characterization of ultra-tough polylactide-based ionic nanocomposites via melt-blending of commercial polylactide (PLA), imidazolium-functionalized poly(ethylene glycol)-based polyurethane (im-PU) and surface-modified sulfonated silica nanoparticles (SiO2–SO3H) using…

Numerical investigation of several twisted tubes with non-conventional tube cross sections on heat transfer and pressure drop

Bruce Indurain y Urricelqui, David Uystepruyst, François Beaubert, Sylvain Lalot, Asdis Helgadottir

Numerical simulations were performed with the open-source CFD software OpenFOAM to investigate the ability of several configurations of short length twisted tube geometries with non-circular cross-section connected to tubes with circular cross-section to induce a swirling flow. The heat transfer…

Are CNNs reliable enough for critical applications? An exploratory study

Mohamed Ayoub Neggaz, Ihsen Alouani, Smail Niar, Fadi Kurdahi

Resource-constrained CNN implementations are subject to various reliability threats. This article provides an exploratory study investigating the impact of faults (soft errors modeled as bit flips) across the parameters of CNNs and the impact on the CNN weights, which can be used to create…

The concept of “safety bubble” for reconfigurable assembly systems

Yves Sallez, Thierry Berger, Thérèse Bonte

In the last decade, Reconfigurable Manufacturing Systems (RMS) have been proposed to deal with mass-customization problems and volatile markets. Applied to the field of assembly, this concept gives rise to Reconfigurable Assembly Systems (RAS). The latter are composed of different basic units (e.g…

How to Select 2D and 3D Roughness Parameters at Their Relevant Scales by the Analysis of Covariance

Stéphane Tchoundjeu Ngatchou, Maxence Bigerelle, Francois Robbe-Valloire, Tony da Silva Botelho, Frédéric Jarnias

In this paper, a multi-scale methodology is proposed to model and characterize the effect of two lubricants on changes in surface morphology during a running-in test. The test concerns two steels samples, mounted on a twin-disc tribometer to test each of lubricants A and B for a period of 42 h. The…

Determination of an Objective Criterion for the Assessment of the Feasibility of an Instrumented Indentation Test on Rough Surfaces

Julie Marteau, Abdeljalil Jourani, Maxence Bigerelle

The influence of roughness on the results of indentation testing was investigated using a semianalytical model. This model used simulated surfaces that were described using three standard roughness parameters: the root-mean-square deviation S q , the wavelength (or cutoff of Gaussian high-pass…
