The dynamics of viscous and elastic threads.
This thesis simultaneously deals with elastic and viscous rods. Their dynamics is ruled by the same set of equations (Kirchhoff equations) despite a difference in... -

Analysis of Jansen's model of a single cortical column
In this report we present a mathematical analysis of a simple model of a cortical column. We first recall some known biological facts about cortical columns. We then... -

Mechanical modeling of crawling cells
The ability of most eukaryotic cells to crawl is essential for embryogenesis, immune response and wound healing while functional abnormalities of crawling can provoke... -
Indeterminacy, bifurcations and unemployment fluctuations
We incorporate imperfectly insured unemployment in the finance constrained economy proposed by Woodford (1986), by introducing unions and unemployment benefits... -

Intermittency in the homopolar disk-dynamo
We study a modified Bullard dynamo and show that this system is equivalent to a nonlinear oscillator subject to a multiplicative noise. The stability analysis of this... -
Structures of a continuously fed two-dimensional <br />viscous film under a d...
This thesis presents the study of the destabilization of a silicone oil under a porous horizontal plane continuously fed.<br />We observe, varying the flow rate... -
On the synchronization and desynchronization of dynamical systems. Applications
This thesis deals with the synchronization and desynchronization of dynamical systems. In a first part we tackle (under a biological viewpoint) the desynchronization... -
Etude du phénomène de bifurcation des écoulements vrillés par la Simulation a...
Swirling flows, which are widely employed in gas turbines, are known to undergo bifurcation between different topologies (large reconfigurations of the flow field)... -
