Effect of the compatilizer and chemical treatments on the performance of poly(lactic acid)/ramie fiber composites

Jianghu Zhan, Guilong Wang, Jiao Li, Yanjin Guan, Guoqun Zhao, Hakim Naceur, Daniel Coutellier, Jun Lin

Natural fiber composites are of great potential for renewability and environmental friendless, but the poor interfacial bonding between the fiber and polymer matrix limits its engineering applications. In the present study, the mechanical strength of the poly (lactic acid) (PLA)/ramie fiber…

Mechanical modelling of microwave sintering and experimental validation on an alumina powder

Maxence Renaux, Damien Méresse, Julien Pellé, Anthony Thuault, Céline Morin, Christelle Nivot, Christian Courtois

Microwave sintering (MW) allows fast heating (≤30 min) and densification of ceramic materials, like alumina Al2O3. In order to predict the final material properties (density, size and grain size) the mechanical SOVS (Skorohold Olevsky Viscous Sintering) model is adapted and validated for…

Human and Cobot Cooperation Ethics: The Process Management Concept of the Production Workplace

Felicita Chromjakova, Damien Trentesaux, Michael Adu Kwarteng

The competitiveness of modern companies depends today on the ability to implement digitised technologies into production processes in human-friendly ways. The aim of this paper is to analyse ethical aspects of human-cobot cooperation in industrial production and to design a process standard aimed…

Computational Fluid Dynamics Investigation of the Thermal Performances of a Swirler with Profiled Blades

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

Numerical simulations were carried out to investigate the swirling decaying flow generated by a novel axial guide vane swirler with profiled blades and no supporting device in a tube and its effect on heat transfer and pressure drop compared to a developed turbulent flow in a no swirl tube.…

Rotten Green Tests in Java, Pharo and Python

Vincent Aranega, Julien Delplanque, Matias Martinez, Andrew P Black, Stéphane Ducasse, Anne Etien, Christopher Fuhrman, Guillermo Polito

Rotten Green Tests are tests that pass, but not because the assertions they contain are true: a rotten test passes because some or all of its assertions are not actually executed. The presence of a rotten green test is a test smell, and a bad one, because the existence of a test gives us false…

Effect of blast loading on the risk of rib fractures: a preliminary 3D numerical investigation

Lorenzo Taddei, Anthony Bracq, Rémi Delille, Benjamin Bourel, Christophe Maréchal, Franck Lauro, Sébastien Roth

Blast is a complex phenomenon which needs to be understood, especially in a military framework, where this kind of loading can have severe consequences on the human body. Indeed, the literature lists a number of studies which try to investigate the dangerousness of such a phenomenon, both at…

Anatomy and biomechanics of healthy and arthritic trapeziometacarpal joints, Anatomie et biomécanique de l'articulation trapézo-métacarpienne saine et arthrosique

Christian Fontaine, P. D’agostino, Catherine Maes-Clavier, M. Boutan, Nadine Sturbois-Nachef

Understanding the biomechanics of the trapeziometacarpal (TMC) or first carpometacarpal (CMC1) joint, the pathophysiology of basal thumb arthritis, the design and performance of surgical procedures require a solid anatomical basis. This review of literature summarizes the most recent data on the…, La compréhension de la biomécanique de l’articulation trapézo-métacarpienne (ATMC), de la physiopathologie de la rhizarthrose, la conception et la réalisation des gestes chirurgicaux nécessitent de solides bases anatomiques. Cette revue de la littérature synthétise les données les plus récentes…

A Tighter Exact Convex Modeling for Improved LMI-Based Nonlinear System Analysis and Design

Sebastien Delprat, Jorge Alvarez, Marcelino Sanchez Pantoja, Miguel Bernal

This article presents a novel methodology for exact convex rewriting of nonlinear systems that generalizes the well-known sector nonlinearity approach; it allows improving the capabilities of those methodologies based on polytopes and the direct Lyapunov method, which are still an active research…

Fault diagnosis for discrete events systems described by partially observed Petri nets

Fayssal Arichi, Brahim Cherki, Mohamed Djemai, Seddik M Djouadi

Fault diagnosis problem is discussed for discrete events systems described by partially observed Petri nets. Our goal is to detect and identify faults that may have occurred in both transitions and places assuming that we can measure some of them. The proposed approach is based on two mains steps (…

A Comparative Study of Machine Learning Models for Predicting Length of Stay in Hospitals

Rachda Naila Mekhaldi, Patrice Caulier, Sondès Chaabane, Abdelahad Chraibi, Sylvain Piechowiak

There has been a growing interest in recent years in correctly predicting the Length of Stay (LoS) in a hospital setting. Estimating the LoS on patient' admission helps hospitals in planning, controlling costs and, providing better services. In this paper, we consider predicting the LoS as a…
