Performance Testing of Light Pipes in real weather conditions for a confrontation with Hemera
Daylight offers many possibilities. Its proper use is a major asset to develop the design, energy and environmental quality of a building but also improve the physiological and psychological conditions of the user. New emerging devices, offer the opportunity to improve visual comfort while, providing energy savings. The light pipes are considered as a part […]

An Efficient Study of Scheduling Algorithms with Freidman Test in WiMAX Networks
In this paper, we evaluate and compare our scheduling strategy for various IPTV services traffic over 802.16j networks with several scheduling algorithms such as Strict Priority algorithm (SP), Weighted Round Robin (WRR), and Modified Dynamic Weighted Round Robin (MWRR). The proposed scheme adapts dynamically the scheduler operation to according queue load and QoS constraints. In […]

Optimized Sink node Deployment in WSN Using Genetic Algorithms through Coverage and Cost Constraints
Wireless Sensor Networks (WSN) is the main infrastructure of a smart building. An optimal installation of a WSN is needed to ensure the best operating of the smart building. WSN suffer from a multitude of constraints, the major ones are: (1) optimal coverage (to ensure best QoS), (2) deployment cost (installation cost), and (3) network […]

3D and 2D face recognition based on image segmentation
In this paper we propose a framework for 3D Face Recognition System (3DFRS) using segmentation by grouping of regions of facial images before and after fusion of two modalities (color and depth images). Firstly, the detection of face region is based on the localization of nose tip and integral projection curves. Then, the features resulting […]

Towards Efficient OpenMP Strategies for Non-Uniform Architectures
Parallel processing is considered as todays and future trend for improving performance of computers. Computing devices ranging from small embedded systems to big clusters of computers rely on parallelizing applications to reduce execution time. Many of current computing systems rely on Non-Uniform Memory Access (NUMA) based processors architectures. In these architectures, analyzing and considering the […]

Modélisation d’un plan de maintenance basé sur les systemes multi-agents pour les éoliennes offshore
La maintenance des éoliennes offshore est une tâche complexe et coûteuse qui représente un vrai défit pour l’évolution de cette source d’énergie. La taille des parcs d’éoliennes offshore, la taille des éoliennes elles-mêmes, la distance qui les sépare de la côte, et les conditions météorologiques difficiles rendent non évident l’établissement d’une stratégie de maintenance efficace.

System Engineering and PLM as an integrated approach for industry collaboration management
The aircraft sector is currently changing, such as automotive sector twenty years ago. This tends to modify changes the OEM and suppliers relationship. One of the main OEM developments perspectives is the supplier vertical integration, early in the product life cycle. This supplier’s vertical integration should allow added value by increasing products and process innovations […]

Low-impedance passive component modelling using S-parameter measurements
This paper presents a model of parasitic effects on passive components (resistor, inductor or capacitor) with low or high impedances in large band frequencies. Previous work [1] allowed characterizing passive components using reflection parameter (S 11 ) measurements. Here, it is shown that this technique is not appropriated for components with low and high impedance. […]

OpenMP Transient-Fault Tolerance via Tasks Redundancy on Multi and Many Core Architectures
The increasing need to secure the execution of critical em- bedded applications has fostered the focus on the growing number of failures in today’s systems due to transient faults. Hence, the need for fault tolerant systems and applications is becoming more and more important. Shared memory parallel programs on multi/many core architectures are now widely […]
