Section: Overall Objectives

Sisyphe research program in 2014

In 2014, we continued working on the third topic: Monitoring and control of complex systems. We have studied questions of modeling, identification, signal analysis and control with medical or engineering applications in the continuation of some of the themes presented in Sections 4.1 , 4.2 . Four issues were considered:

- Identification of transmission line characteristics. Our method based on inverse scattering techniques for fault detection and localization in networks of transmission lines has been tested and improved with Qinghua Zhang, Sisyphe member until end 2013, now working with the project-team I4S . See Section 6.1 .

- Cardiovascular signal processing and applications. The numerical tools developed during a study of HFpEF (Heart Failure with preserved Ejection Fraction) have been gathered into a Scilab toolbox. See Section 5.1 .

- Glycemic control in ICUs. This was the last step on this topic with the statistical analysis of the results of the large clinical trial CGAO-REA . See Section 6.3 .

- Modeling and optimizing patient pathways in hospital. In this work, we consider the complex flows of patients along treatment pathways in hospital in order to understand the steps of medical care provided by man and machine, as well as the passage of information that governs these steps. Our goal is to model the qualitative and quantitative aspects of these pathways, simulate their flow, identify problematic areas, and collaborate with medical staff to optimize the pathways in order to reduce medical errors (and near misses), waiting times, and cost.
