National and regional initiatives

Project "OMD" (Optimisation Multi-Disciplinaire)

Opale participates in the RNTL(RNTL: Réseau National des Technologies Logicielles (National Network for Software Technologies, a program supported by the National Agency for Research (ANR))) Project “OMD” for multi-disciplinary optimization (see ). This project was set-up by the CNRT Aéronautique. The involvement of Opale includes two major lines of investigation developed by Post-Doctoral researchers:

  1. To establish the status of multilevel strategies in shape optimization;

  2. To develop efficient techniques for hierarchical model coupling for optimum-shape design in Aerodynamics.

This contract provides the grant supporting the post-doctoral studies of P. Chandrashekarappa, J. Zhao and A. Benzaoui

Project "OMD2" (Optimisation Multi-Disciplinaire Distribuée)

The notion of optimization platform based on distributed and parallel codes is undertaken with a distributed workflow management system running on a grid infrastructure using the ProActive middleware from INRIA, in collaboration with the OASIS project at INRIA Sophia-Antipolis. Renault is the coordinator of this project, which involves also EMSE, ENS Cachan, EC Nantes, Université de Technologie de Compiègne, CD-Adapco, Sirhena, Activeon, and INRIA project TAO, OASIS and OPALE. This contract provides the grant supporting two PhD theses.

E-Lab Opratel

The collaboration with France Télécom and Thalès Défense led to the creation of the e-lab Opratel in which we develop models for array antennas for telecommunication purposes. Our activity is divided in two main themes:

development of models of array antennas for telecommunication purposes; a patent will shortly be deposited;

frequency allocation, a difficult modeling topic of major importance for our industrial partners.

More specifically, the classical problem of frequency allocation is a main activity. This problem results in a very acute technological challenge today due to the numerous systems operating concurrently (interference of radar, surveillance systems, telephone, radio, television, domestic electronics, electromagnetic noise of WIFI, etc.). Since the channels are limited, special techniques are envisaged to support these systems (orthogonal waves, coding, dynamic occupation of the spectrum).
