Mesh Twisting Technique for Swirl Induced Laminar Flow Used to Determine a Desired Blade Shape

Asdis Helgadottir, Sylvain Lalot, François Beaubert, Halldor Pálsson

Swirling flow has been shown to increase heat transfer in heat exchangers. However, producing swirl while not presenting a severe pressure drop can be a challenge. In this paper, a desired shape of guidance blades for laminar swirl flow is determined by numerical simulation in OpenFOAM. Emphasis is…

Implementing advanced Takagi-Sugeno controllers: application to throttle control of a gasoline engine

Thomas Josso-Laurain, Jimmy Lauber, Reinaldo Martinez Palhares

This paper is dedicated to the implementation process of advanced Takagi-Sugeno controllers. The considered application is the control of the throttle of a gasoline engine running at idle speed. In order to design a model-based control, a model is first obtained and identified with an engine test…

Razumikhin-type Theorems on Practical Stability of Dynamic Equations on Time Scales

Bacem Ben Nasser, Michael Defoort, Mohamed Djemai, Taous-Meriem Laleg-Kirati

In this work, we investigate some Razumikhin-type criteria for the uniform global practical asymptotic stability on arbitrary time domains, for time-varying dynamic equations. Using Lyapunov-type functions on time scales, we develop appropriate inequalities ensuring that trajectories decay to the…

High performance LDPC codes for high spectral efficiency

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Achieving high spectral efficiency is the key requirement of future wireless systems and mobile communications because it provides us a high quality for high data over a limited bandwidth. In order to achieve high spectral efficiency, channel coding and modulation are the key part. Basically, high…

LMI-Based Exponential Estimates for Time-Delay Nonlinear Descriptor Systems ⁎ ⁎This work has been supported by the postdoctoral fellowship for CVU 366627, the ITSON Projects PROFAPI CA-18 2017-0088 and 2018-1062, and PFCE 2016-17. Juan Carlos Arceo was student at ITSON under CONACYT scholarship 415714 during the realization of this work.

Juan Carlos Arceo Luzanilla, Raúl Villafuerte, Víctor Estrada Manzo, Miguel Bernal

This paper presents novel results on exponential estimates for time-delay nonlinear descriptor systems with nonsingular left-hand side. By means of a Lyapunov-Krasovskii functional and an exact convex representation of the system, conditions in the form of linear matrix inequalities are found that…

An Incremental Physically-Based Model of P91 Steel Flow Behaviour for the Numerical Analysis of Hot-Working Processes

Alberto Murillo-Marrodán, Eli Saúl Puchi-Cabrera, Eduardo Garcia, Mirentxu Dubar, Fernando Cortes, Laurent Dubar

This paper is aimed at modelling the flow behaviour of P91 steel at high temperature and a wide range of strain rates for constant and also variable strain-rate deformation conditions, such as those in real hot-working processes. For this purpose, an incremental physically-based model is proposed…

The industrial management of SMEs in the era of Industry 4.0, La gestion industrielle des PME à l'ère de l'industrie 4.0

Alexandre Moeuf, Robert Pellerin, Samir Lamouri, Simon Tamayo, Rodolphe Barbaray

Industry 4.0 provides new paradigms for the industrial management of SMEs. Supported by a growing number of new technologies, this concept appears more flexible and less expensive than traditional enterprise information systems such as ERP and MES. However, SMEs find themselves ill-equipped to face…

The integration of ERP and inter-intra organizational information systems: A Literature Review

Estefania Tobon Valencia, Samir Lamouri, Robert Pellerin, Patrice Dubois, Alexandre Moeuf

This paper provides an initial systematic review of journal publications on ERP and Information Systems (IS) integration. Three essential types of integration are proposed to analyze the body of the literature (Technical, Business and Socio-Organizational). To complete the review, three additional…

How can video feedback be used in physical education to support novice learning in gymnastics? Effects on motor learning, self-assessment and motivation

François Potdevin, Olivier Vors, Aurore Huchez, M. Lamour, Keith Davids, Christophe Schnitzler

Background: Much of the existing research concerning the use of video feedback (VFB) to enhance motor learning has been undertaken under strictly controlled experimental conditions. Few studies have sought to explore the impact of VFB on the skill learning experience of the students in a structured…
