## Jerome Bastien Seminar

Jérome Bastien, MCU of the Interuniversity Laboratory of Motor Biology (LIBM), Lyon I University, will give a seminar in Bordet Room, Thursday 26/04/2018, 14:00

** Title **: Friction, Identification in Biomechanics and train circuits.

** Summary **: I worked on the modeling of friction laws on dynamic systems with finite number of degrees (theoretical results of existences and uniqueness and convergence of numerical schemes). These models have, among other things, been used to model real systems (engine belt tensioner or rolling vehicles). For about ten years, I am interested in the modeling of the movement within the CRIS, become LIBM. From experimental data, procedures for identifying biomechanical parameters have been developed in the case of some simple movements.

Recently, the complete analytical description of the plane workspace (the area of the plane that can reach the distal end of the upper limb of a human for example) has been proposed, in a purely geometric way, without any symbolic calculation, such as is usually done.

At the same time, a patent was filed in 2012 on miniature train tracks. In addition to theoretical enumeration results, oddly resembling the notion of self-avoiding polygons, a didactic and geometric use by this game is being exploited for high school students.

I will expose all of this work from the presentation, simplified and updated, of my HDR (2013), available on http://utbmjb.chez-alice.fr/recherche/articles_provisoires/HDRtranspa_Jbastien.zip

## Seminar by Arbi Moses-Badlyan on “Open State Space Formulation of Reactive Mixtures”

# ANNULE

The seminar presented by Arbi Moses-Badlyan (Technical University of Berlin) will take place on Thursday 7 December at 14:00 in room J. Bordet on the following subject:

**Title**: Open State Space Formulation of Reactive Mixtures

Complex physical systems have been successfully modelled as metriplectic systems, which are state space formulations that have become famous under the acronym GENERIC (General Equation for the Non-Equilibrium Reversible Irreversible Coupling). GENERIC is typically formulated for isolated systems and consist of two main parts, a Hamiltonian part represented by a Poisson bracket and an entropic part represented by a so called dissipation bracket.

In this talk I present results of a joint work were we have been able to set up an operator based open state space formulation that encodes the weak-formulation of the partial-differential field equations describing the dynamics of a reactive mixture of viscous heat-conducting Newtonian fluids. Our operator based open state space formulation via duality pairing induces a bracket formulation that has the properties of a metriplectic system such that the first and in particular the second law of thermodynamics are satisfied.

## Seminar of Professor A. J. van der Schaft, University of Groningen

A seminar will be given by Professor A. J. van der Schaft of the University of Groningen, visiting professor at LAGEP on Thursday 19 October 2017 at 14:00 in room G111.

The title and summary of this seminar are:

**Title**: Stabilization of optimal supply-demand values for power networks

**Abstract**: Key constraint in the control of power networks is supply-demand matching, where the total consumed power is equal to the total generated power. Optimization of the so-called social welfare function under the constraint of supply-demand matching leads to an optimal set-point for the operation of the power network. Continuous-time implementation of the primal-dual gradient algorithm converging to this optimal set-point defines a distributed dynamical controller for the physical power network. It will be shown that the optimal set-point is an asymptotically stable equilibrium of the resulting closed-loop system. Main idea in the proof is the port-Hamiltonian modeling of the physical network, as well as of the primal-dual gradient controller, leading to an insightful Lyapunov function.

## ” From Doctorate to Employment “

The Université de Lyon proposes in the section “Doctorat”, the setting up of a new system initiated by the Department of Doctoral Studies at the University of Lyon, with the expertise of OPE (Objective for Employment), ” From Doctorate to Employment “.

It is presented in the form of a six-month program led by experts, for the support of doctors tailored to the search for a permanent job outside the academic sector. This course is based on a collective dynamic led by professional trainers, and associated with a personalized accompaniment adapted to their profile.

The program of the device, with the contacts to be taken, is
