An evidential network approach to support uncertain multiviewpoint abductive reasoning

Felipe Aguirre, Mohamed Sallak, Frédéric Vanderhaegen, Denis Berdjag

The paper proposes an approach to support human abductive reasoning in the diagnosis of a multiviewpoint system. The novelty of this work lies on the capability of the approach to treat the uncertainty held by the agent performing the diagnosis. To do so, we make use of evidential networks to…

Compilation optimization exploration for thermal dissipation reduction in embedded systems

Ben Saad Montassar, Ahmed Jedidi, Smail Niar, Mohamed Abid

The ever-increasing transistor integration density has allowed to design complex and powerful system-on-chips (SoC). As a consequence, the power density also increased significantly in the SoC, as well as, the accompanying heat. These two results have a negative impact on the performance of the SoC…

Energy consumption in reconfigurable mpsoc architecture: Two-level caches optimization oriented approach

Asmaa Bengueddach, Benaoumeur Senouci, Smail Niar, Bouziane Beldjilali

In order to meet the ever-increasing computing requirement in embedded market, multiprocessor chips were proposed as the best way out. In this work we investigate the estimation of the energy consumption in embedded MPSoC system. One of the efficient solutions to reduce the energy consumption is to…

Efficient FPGA implementation of H.264 CAVLC entropy decoder

Ali Siblini, Elias Michel Baaklini, Hassan Sbeity, Ahmad Fadlallah, Smail Niar

Multiprocessor-system-on-a-chip (MPSoC) is the dominating architecture in embedded systems. Applications need to be multi-threaded to benefit from the concurrency provided by the MPSoC. Many parallel versions of the new emerging H.264/AVC [1] already exist. However, providing a full parallel H.264…

Personnalisation géométrique et mécanique multi-échelles du thorax humain, Mechanical and geometrical multiscale personalisation of the human thorax

Olivier Mayeur

La recherche en biomécanique des chocs est une nécessité pour améliorer la sécurité dans les transports. Pour une meilleure évaluation des critères lésionnels lors des simulations de crash, le manque de représentativité des modèles EF du thorax humain pourrait être comblé par une démarche de…, For a better assessment of injury criteria on the human thorax, realistic numerical simulations need accurate geometrical characterization and an understanding of the mechanical behavior of the rib. Thelack of representation of the FE models of the human thorax could be filled by a personalization…

Experimental Study of Heat Transfer Inside a Gamma Stirling Engine Regenerator During Quasi-Steady Operation

Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

The Stirling engine is a renewable way to confront the lack of fossil energy over the word, to reduce the pollution and to use a free way of energy. Actually, these engines are used to produce electricity, to pump water, etc. Unfortunately, this type of engine is the seat of several thermal and…

Use of the POD and the Coherent Structure Detection Criteria to Study the Flow Dynamics Downstream a Confined Square Obstacle

Wafik Abassi, Fethi Aloui, Sassi Ben Nasrallah, Jack Legrand, Larbi Labraga

Studying the concept of the vortex is an essential tool in the comprehension of fluid dynamics. Despite this, it is still very difficult to find a universal definition of a vortex. Several methods of detection and characterization of vortex structures has been developed and performed. Specifically…
