Two-dimensional heat transfer coefficients with simultaneous flow visualisations during two-phase flow boiling in a PDMS microchannel

Sofia Korniliou, Coinneach Mackenzie-Dover, John R.E. Christy, Souad Harmand, Anthony J. Walton, Khellil Sefiane

Infrared (IR) thermography was combined with simultaneous high speed flow visualisation and pressure measurements from integrated pressure sensors inside the microchannel, in order to produce two-dimensional (2D) high spatial and temporal resolution two-phase heat transfer coefficient (HTC) maps…

Functional and Corticomuscular Changes Associated with Early Phase of Motor Training

Sylvain Cremoux, Dimitri Elie, Cecilie Rovsing, Helene Rovsing, Mads Jochumsen, Heidi Haavik, Imran K. Niazi

This study aimed to evaluate the corticomuscular changes associated with motor training. We quantified functional and corticomuscular changes during a four-days motor training. Results revealed better functional performance and increased magnitude of corticomuscular coherence in the 8–13 Hz…

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…

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 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-…

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…

Current Signal Analysis of an Induction Machine with a Defective Rolling Bearing

Aroua Fourati, Adeline Bourdon, Didier Remond, Nabih Feki, Fakher Chaari, Mohamed Haddar

With the ultimate goal of rotating machinery diagnosis using Motor Current Signal Analysis (MCSA), this paper provides a coupled electro-magnetic-mechanical model of a rotating shaft supported by rolling bearings and driven by a three-phase squirreled cage motor. The modeling is based on the…

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.…
