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…

Implementation of standard penalty procedures for the solution of incompressible Navier–Stokes equations, employing the element-free Galerkin method

Juan Carlos Álvarez-Hostos, Victor D. Fachinotti, Alirio J. Sarache Piña, Alfonso D. Bencomo, Eli Saúl Puchi-Cabrera

The present work introduces an alternative implementation of the element-free Galerkin method (EFGM) for the steady incompressible Navier–Stokes equations. The linear momentum balance and mass conservation equations have been developed on the basis of this global weak formulation. The weak forms of…

Hydrodynamic oscillations inside deep cavities with wall offset

Denis Cornu, Marc Lippert, Franck Kerhervé, Fethi Aloui, Laurent Keirsbulck

The paper focuses on the pressure amplitude response of deep cavities at low Mach numbers with wall offset between the leading and trailing edges. Three wall offsets of , and are considered for different Reynolds numbers and values of length-to-depth ratio (=0.24, 0.48 and 0.65). Present…

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…

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…

Direct Compression Loading Using the Pre-stretched Bar Technique: Application to High Strains Under Moderate Strain Rates

Grégory Haugou, Hervé Morvan, Nicolas Leconte

The mechanical properties of ductile materials are of high interest in the domain of energy absorption, high speed forming processes, machining processes and ballistics. The range of the intermediate strain rates has always been required for the main testing devices, particularly for classical…
