Stability analysis of switched linear systems on non-uniform time domain with unstable subsystems

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai, Serge Nicaise

In finite element computations, the choice of the mesh is crucial to obtain accurate solutions. In order to evaluate the quality of the mesh, a posteriori error estimators can be used. In this paper, we develop residual-based error estimators for magnetostatic problems with both classical…

Marangoni Flow Induced Evaporation Enhancement on Binary Sessile Drops

Pin Chen, Souad Harmand, Safouene Ouenzerfi, Jesse Schiffler

The evaporation processes of pure water, pure 1-butanol, and 5% 1-butanol aqueous solution drops on heated hydrophobic substrates are investigated to determine the effect of temperature on the drop evaporation behavior. The evolution of the parameters (contact angle, diameter, and volume) during…

Predicting fluorescence quantum yield for anisole at elevated temperatures and pressures

Qianlong Wang, Khanh-Hung Tran, Céline Morin, Jérôme Bonnety, Guillaume Legros, Philippe Guibert

Aromatic molecules are promising candidates for using as a fluorescent tracer for gas-phase scalar parameter diagnostics in a drastic environment like engines. Along with anisole turning out an excellent temperature tracer by Planar Laser-Induced Fluorescence (PLIF) diagnostics in Rapid Compression…

Thermal Topology Optimization of a Three-Layer Laminated Busbar for Power Converters

Oriol Puigdellivol, Damien Méresse, Yvonnick Le Menach, Souad Harmand, Jean-Francois Wecxsteen

This paper focuses on a topology optimization method for laminated busbars in power converters that minimizes the quantity of copper used while keeping the temperature under the allowed limits. Busbars are widely studied for adding their stray inductance to the commutation loop, which causes surge…

Investigation of the Driver’s Arm Viscoelastic Properties During Steering Vehicle Maneuver

Alaa Marouf, Philippe Pudlo, Chouki Sentouh, Mohamed Djemai

Driver's arm viscoelastic properties during steering vehicle maneuver are very important information to understand how the driver regulates his torque and they could be used to design a new driver assistance system. This correspondence paper investigates the driver's arm viscoelastic…

A multi-topographical-instrument analysis: the breast implant texture measurement

Charles Garabédian, Rémi Delille, Raphaël Deltombe, Karine Anselme, Michael Atlan, Maxence Bigerelle

Capsular contracture is a major complication after implant-based breast augmentation. To address this tissue reaction, most manufacturers texture the outer breast implant surfaces with calibrated salt grains. However, the analysis of these surfaces on sub-micron scales has been under-studied. This…

Influence of Road Excitation and Steering Wheel Input on Vehicle System Dynamic Responses

Zhen-Feng Wang, Ming-Ming Dong, Liang Gu, Jagat Jyoti Rath, Yechen Qin, Bin Bai

Considering the importance of increasing driving safety, the study of safety is a popular and critical topic of research in the vehicle industry. Vehicle roll behavior with sudden steering input is a main source of untripped rollover. However, previous research has seldom considered road excitation…

Influence of the heat affected zone on the dynamic behavior of a welded joint of armoured steel

Julien Carrier, Eric Markiewicz, Grégory Haugou, David Lebaillif, Nicolas Leconte, Hakim Naceur

Welded joints are often weakened areas due to geometrical stress concentration and heterogeneous materials. This study analyses both the dynamic strain rate sensitivity of materials constituting an armoured steel fillet welded joint: Base Metal (BM), Heat-Affected Zone (HAZ) and Welded Metal (WM),…

Model-Driven Approach for Early Power-Aware Design Space Exploration of Embedded Systems

Fériel Ben Abdallah, Chiraz Trabelsi, Rabie Ben Atitallah, Mourad Abed

Due to the growing complexity of Systems-on-Chip (SoC) and the increasing cost of their redesign and fabrication, industrials are urgently looking for design methodologies allowing them to identify issues early in the design flow and to explore the largest possible space of solutions. Several…
