Urban Digital Twins for Adaptive Water Quality Monitoring in Smart Cities: A Robotics-Based Approach

Umar Alfa, Auwal Shehu Tijjani, Luc Fabresse, Eric Duviella, Raymond Houe Ngouna

<div><p>Urban water resources face increasing threats from pollution and climate change. These challenges necessitate adaptive management strategies that traditional monitoring methods cannot adequately provide. This paper introduces a system architecture for the closed-loop integration…

Multiscale and Multiphysics Topographical Analysis of Brake Friction Material Related to Friction Performance

Robin Guibert, Maël Thévenot, Julie Lemesle, Laurent Coustenoble, Jean-François Brunel, Philippe Dufrénoy, Maxence Bigerelle

Friction braking is the most spread braking system in vehicles, where the morphologies of the disc and the braking pads are essential to ensure that friction reduces rotation speed efficiently. However, modern braking systems are submitted to a complex balance between functionalities: braking…

Distributed Model Predictive Control for Multi-Agent Systems, Controle prédictif distribuée pour les systèmes multi-agents

Abdullateef Ogundipe, Yiwen Chen, Auwal Shehu, Michael Defoort

This work proposes a navigation scheme that addresses the problem of collision-free navigation of multiple non-holonomic mobile robots in the presence of non-coupled and coupled state constraints, and input constraints. The scheme named a two-stage distributed model predictive control (DMPC), in…

Modeling and analysis of swirling flow in cyclone separators using various hybrid scale-resolving approaches

Mustafa Ishak Benzaza, David Uystepruyst, François Beaubert, Damien Méresse, François Delcourt, Céline Morin

This work investigates both experimentally and numerically the turbulent flow within cyclonic separators using DES and VLES turbulence methods. Numerical predictions are validated against Hoekstra’s experimental data, showing that DES accurately captures the tangential velocity and pressure drop,…

Influence of the PEO treatment time and sol-gel sealing on the corrosion resistance of AA1050 and AA2024, Influence de la durée du traitement PEO et du colmatage par voie sol-gel sur la résistance à la corrosion des alliages d’aluminium AA1050 et AA2024.

José Rakotonirina, Lara Moreno, Alex Montagne, Yoann Paint, Marie-Georges Olivier

Plasma Electrolytic Oxidation (PEO) is primarily used as a surface treatment technique to improve the corrosion resistance and mechanical properties of aluminium alloys. This environmentally friendly process uses plasma micro-discharges to produce an adherent, hard and wear resistant oxide layer.…

Scalable multitask Gaussian processes for complex mechanical systems with functional covariates

Razak Christophe Sabi Gninkou, Andrés F. López-Lopera, Franck Massa, Rodolphe Le Riche

Functional covariates arise in many scientific and engineering applications when model inputs take the form of time-dependent or spatially distributed profiles, such as varying boundary conditions or changing material behaviours. In addition, new practices in digital simulation require predictions…

Foam cleaning in closed circuits: effect of surfactant type on foam structure and Bacillus subtilis spore removal from stainless steel surfaces

Ahmad Al Saabi, Heni Dallagi, Piyush Kumar Jha, Fethi Aloui, Thierry Benezech, Christine Faille

Foam cleaning represents an environmentally and economically attractive alternative to conventional cleaning-in-place (CIP) processes for removing microbial contamination in food and bioprocessing industries. This study systematically compared three surfactants, sodium dodecyl sulfate (SDS),…

Scalable Sparse Co-Kriging for Multi-Fidelity Data Fusion : An Application to Aerodynamics

Mauricio Castaño-Aguirre, Andrés F. López-Lopera, Nathalie Bartoli, Franck Massa, Thierry Lefebvre

Multi-fidelity Kriging surrogate modeling combines data of varying accuracy, such as experimental tests and numerical simulations, to improve predictive performance. Autoregressive models are commonly used to capture correlations across fidelity levels, offering interpretability compared to purely…
