On the consensus tracking investigation for multi-agent systems on time scale via matrix-valued Lyapunov functions

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

This paper is devoted to the leader–follower consensus problem for high-order multi-agent systems with inherent nonlinear dynamics evolving on an arbitrary time domain. This problem is investigated using the time scale theory. Based on this theory, some sufficient conditions are derived to...

Distributed leader-follower consensus for a class of semilinear second order multi-agent systems using time scale theory

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

The problem of distributed leader‐follower consensus for second‐order linear multiagent systems with unknown nonlinear inherent dynamics is investigated in this paper. It is assumed that the dynamic of each agent is described by a semilinear second‐order dynamic equation on an arbitrary time scale...

Strain rate effects on the compressive response of wood and energy absorption capabilities – Part B: Experimental investigation under rigid lateral confinement

Jérémy Wouts, Grégory Haugou, M. Oudjene, Hervé Morvan, Daniel Coutellier

The compressive properties of spruce and beech wood species at a large range of strain rates – from 0.001 to 600 – under rigid lateral confinement have been investigated, using an original experimental device especially developed for the purpose. The work is motivated by the need to explore the...

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...
