Bilateral Contracts with Industry

A contract with the HEMERA company was contracted including the internships of Anne Charlier and Lisa Qianru. Hemera designs, produces and sells online liquid and gaz analyzers. It is located in Grenoble. The aim of Hemera is to measure, in any gaseous or liquid environment, with a minimalized environmental impact and in a selective way, all compounds seen nowadays as pollutants : for our health, for an industrial process, etc. Hemera's analyzers measure gaz concentrations using optical techniques. The goal of the collaboration was to investigate the use of statistical methods to improve both the determination of the present gaz and their respective concentrations from the analysis of spectra representing a mixture of the different gaz. A preliminary study based on the Lasso technique was implemented and tested with promising first conclusions.
