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 […]

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 […]

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. […]

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 […]

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 […]

Modelling of maintenance strategy of offshore wind farms based multi-agent system
The maintenance of offshore wind turbines is a complex and costly task which represents a barrier to the development of this source of energy. The combination of the size of the farm and the size of the turbines themselves, the distance from the coast and difficult meteorological conditions make the choice of maintenance strategy difficult. […]

Towards Supplier Maturity Evaluation in Terms of PLM Collaboration
The product lifecycle management (PLM) system has a significant role to support the collaboration and manage the partnership between OEM and supplier to enable the success of supplier integration. Today great rates of cooperation as suppliers have been dedicated to SMEs. Since one of the PLM task is to control the collaboration between OEM and […]

A Framework for Improving the Sharing of Manufacturing Knowledge through Micro-Blogging
The purpose of this paper is to report on an industrial investigation, conducted within a leading power generation manufacturer, to better understand the organisational processes and challenges present in relation to the management and sharing of knowledge during product manufacturing. Findings reveal that the organisation is failing to fully benefit from web 2.0 technologies and […]

Simulation-based optimization of sampling plans to reduce inspections while mastering the risk exposure in semiconductor manufacturing
Semiconductor manufacturing processes are very long and complex, needing several hundreds of individual steps to produce the final product (chip). In this context, the early detection of process excursions or product defects is very important to avoid massive potential losses. Metrology is thus a key step in the fabrication line. Whereas a 100% inspection rate […]

Flexible Job Shop Models for Solving Scheduling and Layout Problems Using Coloured Petri Nets
In this paper we propose models for solving both the layout manufacturing problems and the scheduling manufacturing systems. These models are based on Coloured petri Nets. The particularity of our models is the possibility to include complex programmable functions inside the petri nets models. In our case the programming language is SML/NJ. The advantage of […]

Maturité des PME en termes de PLM
Ce travail est réalisé dans le contexte du projet INTERREG BENEFITS, qui vise à garder les compétences locales en termes de technologies de l’information et de la communication (TIC), plus précisément les technologies PLM. Le choix du PLM est dû à sa capacité de permettre à l’entreprise étendue (incluant les clients et les fournisseurs) d’échanger […]
