A Novel 3D Topography Stitching Algorithm Based on Reflectance and Multimap

Julie Lemesle, Robin Guibert, Maxence Bigerelle

Surface topography is an efficient tool for the understanding of physical phenomena, especially if multiscale roughness analysis is performed. However, the observable scale range in a topography measured with 3D optical profilometers is quite limited. Therefore, all scales linked to a physical…

Coupled experimental and offline simulation study of a helicopter rotor in a frigate airwake with active flow control, Étude expérimentale et simulation hors ligne d'un rotor d'hélicoptère dans le sillage d'une frégate avec contrôle actif de l'écoulement

Elvina Derhille, Quentin Gallas, Luc Bordier, Simon Verley, Laurent Keirsbulck

L’appontage des hélicoptères sur les navires de type frégate demande une forte charge de travail de la part des pilotes. Cet article présente l’effet d’un dispositif de contrôle actif, situé le long des arrêtes du hangar, sur la traction rotor le long d’une trajectoire dans l’axe du navire. Les…

A multi-agent system simulation based approach for collision avoidance in integrated Job-Shop Scheduling Problem with transportation tasks

Kader Sanogo, Abdelkader Mekhalef Benhafssa, M’hammed Sahnoun, Belgacem Bettayeb, Moussa Abderrahim, Abdelghani Bekrar

At the operational level of Flexible Manufacturing Systems (FMS), several research works have developed solutions not fully realizable considering the operational constraints, which can be difficult to model. One of the well-known problems in FMS is the Job-Shop Scheduling Problem (JSSP) with…

Design features of the kinematic chain of the ant exoskeleton

Santiago Arroyave-Tobon, Jordin Drapin, Jean-Marc Linares, Pierre Moretto

New challenges in engineering design are about resilience, frugality and sustainability. Nature offers remarkable examples of successful mechanical designs that respond to those constraints. Therefore, biological systems deserve to be explored from a design perspective. The study of design features…

Martens hardness of Constantan thin films on (100) Si wafer: Improvement in contact area function in nanoindentation

Ayyoub Dziri, Alex Montagne, Francine Roudet, Katir Ziouche, Didier Chicot

This work presents a mechanical study by nanoindentation of Constantan thin films deposited by cathodic sputtering technique with an intermediate thin adhesion layer of titanium on a (100) silicon wafer substrate. A methodology based on a modified contact area function is proposed for a suitable…

Improved high-order integral fast terminal sliding mode-based disturbance-observer for the tracking problem of PMSG in WECS

Chakib Chatri, Moussa Labbadi, Mohammed Ouassaid

The present paper proposes a high-order sliding mode control approach for wind turbine (WT) with a permanent magnet synchronous generator (PMSG) under complex situations. The suggested control approach uses a disturbance observer (DO) with a modified super-twisting integral fast terminal sliding…

Vehicle Actuator Fault Detection With Finite-Frequency Specifications via Takagi-Sugeno Fuzzy Observers: Theory and Experiments

Juntao Pan, Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Chouki Sentouh, Sujun Wang, Jean-Christophe Popieul

Abstract This article investigates the design of Takagi–Sugeno (TS) fuzzy model‐based observers for nonlinear systems with parametric uncertainties and unknown inputs. To address this challenging problem, two observers are constructed in cascade. Based on the sliding mode technique, the first…

A simulation-based approach for assessing the impact of uncertainty on patient waiting time in the operating room

Leah Rifi, Franck Fontanili, Clea Martinez, Maria Di Mascolo, Virginie Fortineau

Demand for surgical care is rising worldwide, making the organization of the operating room (OR) a topic of strong interest. During the last two decades, the number of papers on methods for OR planning and scheduling under uncertainty has increased significantly. However, most hospitals neglect…

Data-based Extended Moving Horizon Estimation for MISO Anesthesia Dynamics

Kaouther Moussa, Bob Aubouin--Pairault, Mazen Alamir, Thao Dang

This paper presents an extended moving horizon observer to estimate both the states and the pharmacodynamic (PD) parameters of an anesthesia model, based on real data. The inputs of this model are the injection rates of Propofol and Remifentanil. The states represent the concentration of the…
