Overall Objectives

SISYPHE (SIgnals and Systems in PHysiology and Engineering) is studying questions about some complex dynamical systems issued from Physiology and Engineering: modeling ; identification and observation from signals ; real-time health monitoring or control ; questions of system theory arising from the emerging domain of “quantum engineering”.

Most studies are motivated, in Physiology, by the reproductive and the cardiovascular systems and in Engineering, by control of some new engineered quantum systems and by monitoring of some critical engineering systems like electrical networks.

The research on the reproductive system, after an important development in the framework of REGATE (REgulation of the GonAdoTropE axis), an Inria Large-Scale Initiative Action (LSIA), will lead to a new team proposed by Frédérique Clément in October 2012.

Research topics:

Signals & Systems

  • Dynamical systems modeled by ordinary differential equations: modeling, observation and control.

  • Quantum & quantum-like systems: estimation and control.

  • Multiscale dynamical systems: analysis of multiscale properties of signals and relations with the underlying dynamical systems.

Applications to Physiology & Engineering

  • Multiscale modeling of the controlled follicle selection process & Control of the reproductive axis.

  • Model-based observation and control of the cardiovascular system: (multiscale- ) model-based signal processing (ECG, pressure, heart-rate). Monitoring and control of cardiac prosthesis.

  • Identification and control of some quantum systems: towards “quantum engineering”.

  • Waves propagation in transmission-line networks & Inverse scattering. Application to health monitoring of cabled electrical networks and to the arterial pressure waveform analysis.

  • Health monitoring and control of energy conversion systems: glycemic control in critically ill patients ; monitoring of exhaust gas aftertreatment systems.
