Computational fluid dynamical analysis of new obstacle design and its impact on the heat transfer enhancement in a specific type of air flow geometry

Younes Menni, Ahmed Azzi, Faouzi Didi, Souad Harmand

The present work focuses on the study of an interesting topic from different points of view, that is, theoretical, practical, and numerical modeling. This study aims to improve the heat transfer within thermal devices like heat exchangers, solar air collectors, and other electronic equipment; these…

LMI-based 2-DoF control design of a manipulator via T-S descriptor approach

van Anh Nguyen Thi, Tran Anh-Tu Nguyen, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

This paper presents a method for the control design of a manipulator. The design goal is to achieve a guaranteed H∞ model reference tracking performance with respect to bounded reference inputs through a 2-DoF control scheme. To achieve this goal, the manipulator system is represented by a Takagi-…

Toward an Application Guide for Safety Integrity Level Allocation in Railway Systems

Kiswendsida Abel Ouedraogo, Julie Beugin, El Miloudi El Koursi, Joffrey Clarhaut, Dominique Renaux, Frédéric Lisiecki

The work in the article presents the development of an application guide based on feedback and comments stemming from various railway actors on their practices of SIL allocation to railway safety-related functions. The initial generic methodology for SIL allocation has been updated to be applied to…

A framework combining agile, user-centred design and service-oriented architecture approaches for collaborative disaster management system design

Christophe Kolski, K. Ait Abdelouhab, Djilali Idoughi

Disaster management is a special type of human complex organisation in which heterogeneous human actors belonging to different authorities collaborate and work together with the shared aim to solve, or at least reduce, the disaster situation. Thus, the collaboration in this case within team members…

LMI-Based Controller Design for Time-Delay Nonlinear Descriptor Systems with Guaranteed Exponential Estimates

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

This report is concerned with stability and stabilization of time-delay nonlinear nonsigular descriptor systems. Based-on a Lyapunov-Krasovskii functional and an exact convex representation of the system, conditions in the form of linear matrix inequalities are found that guarantee exponential…

Local stabilization of discrete-time TS descriptor systems

Zsofia Lendek, Gábor Nagy, Jimmy Lauber

Descriptor models are naturally obtained from the Euler–Lagrange modeling approach to mechanical systems. Since the underlying system is nonlinear, global stabilization and/or tracking is possible only in a limited number of cases. Therefore, we develop conditions for local stabilization and…

LIDAR and Stereo-Camera fusion for reliable Road Extraction

Mohammed Yazid Lachachi, Mohamed Ouslim, Abdelmalik Taleb-Ahmed, Smail Niar

his paper presents a novel approach that combines LIDAR and Stereo-cameras. First, a stereo camera is used to guide the extraction of road surface points from a 3D point cloud obtained by a LIDAR. Then, the number of points is reduced based on their elevation and illumination invariant colors.…

CFD characterization of a wet foam flow rheological behavior

Heni Dallagi, Ramla Gheith, Ahmad Al Saabi, Christine Faille, Wolfgang Augustin, Thierry Benezech, Fethi Aloui

In some industrial processes, aqueous foams flow presents an important phase of the process, whereas, they cause pressure drop when designing and dimensioning systems. Identifying the different rheological parameters of foam flow is an interest key to understanding the interfacial phenomena.…

DeepHPS: End-to-end Estimation of 3D Hand Pose and Shape by Learning from Synthetic Depth

Muhammad Jameel Nawaz Malik, Ahmed Elhayek, Fabrizio Nunnari, Kiran Varanasi, Kiarash Tamaddon, Alexis Heloir, Didier Stricker

Articulated hand pose and shape estimation is an important problem for vision-based applications such as augmented reality and animation. In contrast to the existing methods which optimize only for joint positions, we propose a fully supervised deep network which learns to jointly estimate a full…

Large-scale fractional-order systems: stability analysis and their decentralized functional observers design

Yassine Boukal, Mohamed Darouach, Michel Zasadzinski, Nour-Eddine Radhy

This study concerns the stability analysis of linear large-scale fractional-order systems and its functional observers design. First, based on the diffusive representation of the fractional-order derivative and the indirect Lyapunov approach, the stability of large-scale fractional-order…
