Some research projects
SEACS
(projet inter labex): Stochastic modEl-dAta-Coupled
representationS for the analysis, simulation and reconstruction
of upper ocean dynamics
This project aims at exploring novel statistical and stochastic
methods to address the emulation, reconstruction and forecast of
fine-scale upper ocean dynamics.
PhD student: Thi Tuyet Trang Chau
DESIRES (ERANET MED) :
This project aims to develop an Internet-based, multi-parametric
electronic platform for optimum design of desalination plants,
supplied by Renewable Energy Sources (RES). The platform will
rely upon 1) a solar, wind and wave energy potential database,
2) existing statistical algorithms for processing energy-related
data, 3) information regarding the inter-annual water needs, 3)
a database with the technical characteristics of desalination
plant units and the RES components, and 4) existing algorithms
for cost effective design, optimal sizing and location selection
of desalination plants.
PREDICTIVE (projet inter labex) : The general objective of the
study is to generate new tools allowing for the exploitation of
the big available amount of heterogeneous data to better adapt
radiotherapy for individuals suffering from prostate cancer.
