Assessing Cyber-Physical Systems to Balance Maintenance Replacement Policies and Optimize Long-Run Average Costs for Aircraft Assets

Marco Andreacchio, Abdelghani Bekrar, Rachid Benmansour, Damien Trentesaux

Many aircraft assets are subject to both preventive (scheduled) and corrective (unscheduled) replacement policies to ensure adequate levels of reliability and availability. The problem, particularly for assets that exist in large quantities, is that preventive replacement tasks often involve...

Study of the Dynamic and Thermal Behaviors of an Air Flow in a T-Bifurcation

Ali Riahi, Julien Pellé, Lilia Chouchene, Souad Harmand, Sadok Ben Jabrallah

This paper presents a numerical and experimental study of a turbulent flow of air in a T-bifurcation. This configuration corresponds to a stator containing radial vents oriented vertically to the rotor–stator air gap in electrical machines. Our analysis focuses on the local convective heat transfer...

HAPE: A high-level area-power estimation framework for FPGA-based accelerators

Mariem Makni, Smail Niar, Mouna Baklouti, Mohamed Abid

Recent embedded applications are widely used in several industrial domains such as automotive and multimedia systems. These applications are critical and complex, involving more computing resources and therefore increasing the power consumption of the system. Although performance still remains an...

HCI in practice: An empirical study with software process capability maturity model consultants in Brazil

Taisa Guidini Gonçalves, Káthia Marçal de Oliveira, Christophe Kolski

Human-computer interaction (HCI) and software engineering (SE) are undoubtedly important domains for the development of interactive systems. The quality of an interactive system is usually considered dependent on the user interface design and evaluation, which implies the use of HCI and SE...

A three-dimensional geometric quantification of human cortical canals using an innovative method with micro-computed tomographic data

Xavier Roothaer, Rémi Delille, Hervé Morvan, Bruno Bennani, Eric Markiewicz, Christian Fontaine

The complex architecture of bone has been investigated for several decades. Some pioneer works proved an existing link between microstructure and external mechanical loading applied on bone. Due to sinuous network of canals and limitations of experimental acquisition technique, there has been...

Human–machine shared control for vehicle lane keeping systems: a Lyapunov‐based approach

Chouki Sentouh, Tran Anh-Tu Nguyen, Jagat Jyoti Rath, Jérôme Floris, Jean‐christophe Popieul

In this work, a human-centred steering assist controller based on dynamic allocation of control authority between driver and automatic e-copilot has been proposed for lane keeping systems. Cooperative control between driver and steering assist controller is addressed taking into consideration human...

Performance over a wide range of strain rate of polypropylene reinforced by short alfa fibers

Mariem Nciri, Delphine Notta-Cuvier, Franck Lauro, Fahmi Chaari, Rémi Delille, Grégory Haugou, Yamen Maalej, Bassem Zouari

Thermoplastics reinforced with short vegetal fibers are appealing materials for technical applications, for instance in automotive, thanks to high specific modulus and at least partially biosourced origin, in particular. However, a more widespread use of those materials is still hampered by a lack...

From MDD to BDD and Arc consistency

Julien Vion, Sylvain Piechowiak

In this paper, we present a new conversion of multivalued decision diagrams (MDD) to binary decision diagrams (BDD) which can be used to improve MDD-based fil- tering algorithms such as MDDC or MDD-4R. We also propose BDDF, an algorithm that copies modified parts of the BDD “on the fly” during the...

Experimental Study of the Liquid/Vapor Phase Change in a Porous Media of Two-Phase Heat Transfer Devices

Riadh Boubaker, Souad Harmand, Vincent Platel

The study presents an experimental examination of heat and mass transfer with phase change in a porous media composed of copper foam. The aim of the study involves separately examining the effect of the adverse hydrostatic head, subcooling at the wick inlet and wick properties (porosity and average...

Whale optimization algorithm based optimal reactive power dispatch: A case study of the Algerian power system

Khaled Ben Oualid Medani, Samir Sayah, Abdelghani Bekrar

Optimal reactive power dispatch (ORPD) is a particular case of the optimal power flow. ORPD was usually considered as the minimization of an objective function representing the total active power losses in the electrical networks. The constraints involved are the generator voltages, tap regulating...
