Finite-time stability and stabilization results for switched impulsive dynamical systems on time scales

Vipin Kumar, Mohamed Djemai, Michael Defoort, Muslim Malik

In this article, we study the finite-time stability (FTS) and finite time stabilization problems for a class of switched impulsive systems evolving on an arbitrary time domain. This problem is formulated using time scale theory where the time domain can be continuous, discrete, union of disjoint…

Computational Reduction of Optimal Hybrid Vehicle Energy Management

Carlos Armenta, Sebastien Delprat, Rudy R Negenborn, Ali Haseltalab, Jimmy Lauber, Michel Dambrine

Pontryagin's Minimum Principle is a way of solving hybrid powertrain optimal energy management. This letter presents an improvement of a classical implementation. The core of this improvement consists in relaxing the tolerance on some intermediate steps of the algorithm in order to reduce the…

Fabrication and optimization of high frequency ZnO transducers for both longitudinal and shear emission: application of viscosity measurement using ultrasound

Hatem Dahmani, Ibrahim Zaaroura, Abbas Salhab, Pierre Campistron, Julien Carlier, Malika Toubal, Souad Harmand, V. Thomy, Marc Neyens, Bertrand Nongaillard

This paper covers the study of high-frequency (~ 1 GHz) ZnO piezoelectric transducer integrated on a silicon substrate able to generate both compressional and shear acoustic waves. First, to promote the longitudinal mode, an electrical matching of the transducer in this high-frequency range is…

A framework for detecting and analyzing behavior changes of elderly people over time using learning techniques

Dorsaf Zekri, Thierry Delot, Marie Thilliez, Sylvain Lecomte, Mikael Desertot

A sensor-rich environment can be exploited for elder healthcare applications. In this work, our objective was to conduct a continuous and long-term analysis of elderly’s behavior for detecting changes. We indeed did not study snapshots of the behavior but, rather, analyzed the overall behavior…

A multiscale topographical analysis based on morphological information: the HEVC multiscale decomposition

Tarek Eseholi, François-Xavier Coudoux, Patrick Corlay, Rahmad Sadli, Maxence Bigerelle

In this paper, we evaluate the effect of scale analysis as well as the filtering process on the performances of an original compressed-domain classifier in the field of material surface topographies classification. Each surface profile is multiscale analyzed by using a Gaussian Filter analyzing…

Etude expérimentale des échanges de chaleur pariétaux dans un refroidisseur d’air suralimenté d’un moteur à combustion interne, Experimental study of wall heat transfers in an intercooler of an internal combustion engine

Maximilien Blanc, François Delcourt, Eric Delacourt, Céline Morin, David Chalet

Des mesures par thermocouples et thermographie infrarouge sont réalisées sur le refroidisseur d’air suralimenté d’un moteur à allumage commandé (cylindrée : 1,2 L, taux de compression : 10,5:1, puissance : 95,6 kW) pour plusieurs points de fonctionnement moteur. Une méthode de calcul est développée…, Experimental measurements by thermocouples and infrared thermography are made in the intercooler of a supercharged spark-ignition engine (engine displacement: 1.2L, compression ratio: 10.5:1, power: 95.6kW) for several engine operating points. A calculation method is developed to define locally the…

Experimental characterization and micromechanical modeling of the elastic response of the human humerus under bending impact

Jamila Rahmoun, Hakim Naceur, Hervé Morvan, Pascal Drazetic, Christian Fontaine, P.-E. Mazeran

This paper investigates the characterization and numerical modeling of the elastic behavior of the human humerus bone using a recently developed micromechanical approach coupled to nanoindentation measurements. At first, standard three-point bending experiments were conducted under low static…

Multimodal Evaluation of the Spatio-Temporal Variations of Periprosthetic Bone Properties

Manon Fraulob, Sophie Le Cann, Benjamin Voumard, Hirokazu Yasui, Keita Yano, Romain Vayron, Mami Matsukawa, Philippe Zysset, Guillaume Haiat

Titanium implants are widely used in dental and orthopedic surgery. However, implant failures still occur because of a lack of implant stability. The biomechanical properties of bone tissue located around the implant need to be assessed to better understand the osseointegration phenomena and…

Quantitative ultrasound assessment of the influence of roughness and healing time on osseointegration phenomena

Manon Fraulob, Romain Vayron, S. Le Cann, Benoît Lecuelle, Yoann Hériveaux, Hugues Albini Lomami, Charles-Henri Flouzat-Lachaniette, G. Haiat

The evolution of bone tissue quantity and quality in contact with the surface of orthopedic and dental implants is a strong determinant of the surgical outcome but remains difficult to be assessed quantitatively. The aim of this study was to investigate the performance of a quantitative ultrasound…
