Une simple heuristique pour rapprocher DFS et LNS pour les COP

Julien Vion, Sylvain Piechowiak

Dans cet article, nous montrons comment une combinaison de stratégies de branchement et de redémarrages pour la recherche en profondeur d’abord (DFS) permet de reproduire le fonctionnement de la recherche par grand voisinage (LNS) pour la résolution de problèmes d’optimisation à contraintes, ce qui…, In this paper, we argue that a combination of wellknown and new search strategies enables Depth First tree Search (DFS) to mimic the behavior of Large Neighborhood Search (LNS), which reduces considerably the gap between the two techniques. In particular, we are able to implement a DFS strategy…

Direct Compression Loading Using the Pre-stretched Bar Technique: Application to High Strains Under Moderate Strain Rates

Grégory Haugou, Hervé Morvan, Nicolas Leconte

The mechanical properties of ductile materials are of high interest in the domain of energy absorption, high speed forming processes, machining processes and ballistics. The range of the intermediate strain rates has always been required for the main testing devices, particularly for classical…

Multi-Physic Analysis of Electrical Machines: Hybrid Electro-Magneto-Aero-Thermal Modeling

Oualid Messal, Louis Lambourg, Frédéric Dubas, Souad Harmand, Afef Lebouc, Christian Chillet

In this paper, a multi-physic approach allowing the accurate analysis of electrical machines is presented. This original approach exploits a generalized nonlinear adaptive magnetic equivalent circuit (MEC), a dynamic hysteresis model and an aerothermal model. The model coupling has been applied to…

An Energy-Aware Learning Agent for Power Management in Mobile Devices

Ismat Chaib Draa, Emmanuelle Grislin-Le Strugeon, Smail Niar

The optimization of the energy consumption in mobile devices can be performed on hardware and software components. For example, reducing the screen brightness or switching off GPS. The energy control must take into account both the current context and user habits, on the base of usage knowledge…

Replication in Fault-Tolerant Distributed CSP

Fadoua Chakchouk, Julien Vion, Sylvain Piechowiak, René Mandiau, Makram Soui, Khaled Ghedira

Real life problems can be solved by a distributed way, in particular by multi-agent approaches. However, the fault tolerance is not guarantee when an agent, for example, does not have any activity (e.g. it dies). This problem is very crucial, when the interactional model is based on a Distributed…

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…

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…

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),…
