Sur la stabilité des systèmes à retards variant dans le temps: théorie et application au contrôle de congestion d'un routeur

This thesis investigates the existing links between the control theory and the communica-tion networks supporting the well-known communication protocol TCP (Transmission ControlProtocol). The key idea consists in using the tools from control theory for the network trafficstabilization. Hence, this manuscript has naturally been turned towards two research lines : thedesign of sta...

Détermination des forces de traction au cours de la migration de cellules cancéreuses sur des gels

The migration process is a physically integrated molecular phenomena that contributes to many physiological motility in vivo processes such as development, immune surveillance and cancer metastasis. To understand cell migration it is necessary to consider the cell’s environment, cell type and morphology as well as the internal organization of the cells, i.e. its cytoskeleton and focal adhesions...

Sur la présence des antigènes solubles dans la culture liquide et aérée de Hemophilus pertussis

Sur La Description Des Formations De . . .

We are interested in nite-time blow-up phenomena for heat equations of the type: @u @t = u+ jujp 1u (1) where u : (x; t) 2 RN [0; T )! R, 1 < p, (N 2)p < N + 2. We rst construct for (1) a solution u which blows-up in nite time T at only one blow-up point x0 2 RN , and describe completely its blow-up pro le (or asymptotic behavior). This construction is based on a priori estimates' technique whi...
