Study of the phenomenon of the interaction between sessile drops during evaporation

Dorra Khilifi, Walid Foudhil, Kamel Fahem, Souad Harmand, Jabrallah Ben

This research work represents an experimental study of the interaction between water drops deposited on a substrate at ambient temperature. To examine this phenomenon, the evaporation of a single drop deposited on a substrate was first investigated. Then, several drops were deposited alongside on...

Optimization of an image-based experimental setup for the dynamic behaviour characterization of materials

Pascal Bouda, Delphine Notta-Cuvier, Bertrand Langrand, Eric Markiewicz, Fabrice Pierron

The present work aims at identifying an elastic-viscoplastic material constitutive model over a wide strain and strain-rate range (up to 0.1 and 1000 s−1 respectively), using the so-called Virtual Fields Method. To define the experimental campaign, a design process has been set. It relies on the...

Propagation of singularities in shells of non-uniform geometrical nature. A numerical investigation

Fabien Béchet

This paper deals with the propagation of singularities in thin elastic shells whose middle surface is not of an uniform nature. Numerical computations are performed using an adaptive mesh procedure proposed by the software Abaqus to refine the mesh inside the internal layers. The computation are...

An alternative LMI static output feedback control design for nonlinear systems represented by Takagi-Sugeno models

Víctor Estrada Manzo, Zsofia Lendek, Thierry-Marie Guerra

This paper presents a static output feedback controller design for discrete-time nonlinear systems exactly represented by Takagi–Sugeno models. By introducing past states in the control law as well as in the Lyapunov function, more relaxed results are obtained. Different conditions in terms of...

Personalised lane keeping assist strategy: adaptation to driving style

Jagat Jyoti Rath, Chouki Sentouh, Jean-Christophe Popieul

The research in advanced driver assistance systems (ADAS) has progressed to design architectures for driver specific performance. Personalised ADASs in this aspect have been developed with adaptation to driver attributes, state, style, behaviour, skill and so on. For the lane keeping task, the...

De l'optimisation des opérations à l’alignement stratégique

Said Hanafi, Michel Labour, Igor Crevits

L’alignement stratégique repose sur les deux phases d’adaptation de la stratégie et d’intégration fonctionnelle au sein de l’organisation qui présentent une dimension décisionnelle importante. Les technologies de l’information offrent un pouvoir structurant à l’organisation mais également de..., Strategic alignment relies on both adaption of strategy and functional integration inside the organisation which refer to decisions. Information technologies allow improving the structure of the organisation and offer new opportunities which can extend to the market outside the organisation....

On the Local Stabilization of Hybrid Limit Cycles in Switched Affine Systems

Mohammed Benmiloud, A. Benalia, Mohamed Djemai, Michael Defoort

Most of the proposed controllers for switched affine systems are able to drive the system trajectory to a sufficiently small neighborhood of a desired state. However, the trajectory behavior in this neighborhood is not generally considered despite the fact that the system performance may be judged...

Model free active flow control of a simplified car model

Baptiste Plumejeau, Sebastien Delprat, Laurent Keirsbulck

A model free control (MFC) approach is presented and used to symmetrize the unstable wake flow of a simplified car model named Ahmed body. Such unstable phenomena with regards to the space-time evolution of the low pressure wake vortex core, is known to increase the global drag of square back...

Conductimetry technique for the measurement of thin liquid film thickness between two solid surfaces in relative motion: hydrodynamic lubrication

Fethi Aloui, Lamia Gaied, Wafik Abassi, Marc Lippert, Maxence Bigerelle

This paper presents an approach for the measurement of a liquid film thickness in contact with a rough surface, based on electrical conductance sensor. This type of sensor consists of two electrodes mounted flush on a wall and using an electrolyte solution representing the liquid film. Assessing of...

A comparative Study of Sorting Algorithms with FPGA Acceleration by High Level Synthesis

Yomna Ben Jmaa Chtourou, Ahmed Ben Atitallah, David Duvivier, Maher Ben Jemaa

Nowadays, sorting is an important operation for several real-time embedded applications. It is one of the most commonly studied problems in computer science. It can be considered as an advantage for some applications such as avionic systems and decision support systems because these applications...
