ANR

ANR PREVASSEMBLE

This new application domain concerns the application of the particle filter technology and more general sequential Monte Carlo methods to data assimilation problems arising in forecasting. The ALEA team project is involved in the ANR 2008 selected project PREVASSEMBLE with Météo France Toulouse, the INRIA Rennes and the LMD in Paris.

ANR MODECOL

This application domain of evolutionary computing is concerned with the design of ecological systems, mixed-species models and prairial ecosystems. For more details, we refer the reader to the web site of the Virtual Prairie project The ALEA project is a partner of the 2008 ANR SYSCOM project named MODECOL.

ANR Nebbiano

The terminology watermarking refers to a set of techniques for imbedding/hiding information in a digital audio or video file, such that the change is not noticed, and very hard to remove. In order to be used in an application, a watermarking technique must be reliable. Protection false alarms and failures of traceability codes are practically not achievable without using rare event analysis. This application domain area of particle rare event technology is the subject of joint ANR 2007 research project with the IRISA-INRIA in Rennes and the LIS INPG in Grenoble. For more details, we refer the reader to the website of the Nebbiano project. Security and Reliability in Digital Watermarking

ANR Viroscopy

This project aims at developing stochastic mathematical models for the spread of transmissible infectious diseases, together with dedicated statistical methodologies, with the intent to deliver efficient diagnostic/prediction tools for epidemiologists. This application domain area of particle rare event technology is the subject of joint ANR 2008 research project with Telcom Paristech, the Laboratoire Paul Painlevé in Lille 1 and the University of Paris 5 (cf. Programme Systèmes Complexes et Modélisation Mathématique, list of 2008 selected projects ).

ANR Propagation

To combat dramatic event such as happened in Bombay last year (coming from the sea, a terrorist commando killed more than 200 peoples in Bombay city), authorities are decided to deploy efficient sea surveillance system to protect coastal zone including sensitive infrastructures often in vicinity of important cities.

Regulation on frequencies allocation and on coastal constructions is strong constraint to be taken into account to install technical capabilities to permanently survey vulnerable littoral zones. For example, new active sensor shall be frequencies compatible within numerous existing ones in inhabited region. In this context to perform coastal surveillance, attractive solution is to deploy passive sensors networks because:

• Not necessarily compatible within existing active sensors network.

• Provide large possibilities to install the passive sensors, because, it is not needed to be on the shoreline, but can be deployed inside the territory. Such as facility offers more potential sites and then, to optimise the deployment for optimal coverage of the sensitive zone.

• Is totally undetectable by external technical means in hand of structured criminal organisations.

For these objectives, the PROPAGATION project will study, develop and experiment a demonstrator to carry out maritime traffic picture from a set of passive sensors: passive radar, AIS and optronic cameras deployed over a coastal site. This is a joint ANR project with DCNS, Thalès, Ecomer and Exavision, accepted in 2009 .

ARC INRIA

ARC EPS

This project aims at developing stochastic models and algorithms for the analysis of bacteriology ecosystems, especially in food safety. The objective is to predict and control critical risk of proliferations. This is the subject of joint research project with the INRA of Paris and Montpellier, the University of Bretagne and ENV Alford.

ARC M2A3PC

The spread of a pathogen within a strongly anthropized perennial vegetal cover depends on many parameters acting at contrasted spatio-temporal scales. This is of paramount importance for vine and apple trees and their airborne obligated parasites (powdery and downy mildew, scab) which strongly rely on the susceptibility and status of their hosts. Both crop systems require from 17 to 20 fungicide treatments per year. Sustainable crop management goes through a better understanding of the dynamics of these epidemic diseases at various spatio-temporal scales. With this in mind we aimed at developing a plant-pathogen methodology at several spatio-temporal scales. Dedicated teams from INRIA, INRA, CIRAD and CNRS research institutes joined together to form a task force with well-known abilities on :

• the overall dynamics of vine and apple tree systems studied at the desired spatio-temporal scales, in biology, epidemiology and agronomy at the plant and lanscape scales.

• modelling and 3D vizualisation of perenial plant growth coupled to development of pathogens,

• mathematical modelling and numerical simulations of epidemic diseases propagation within a growing host population, including spatial spread of pathogens at different scales.
