Nous présentons une technique pour caractériser la cascadabilité et la résistance au bruit d'un régénérateur optique. L'impact du rapport signal sur bruit optique sur les performances du régénérateur ainsi que l'efficaci...
-
Providing service discovery in an efficient and scalable way in ad hoc networks is a challenging problem, in particular for multihop scenarios, due to the large number of potential participant nodes and the scarce resource...

The cost of universal free access for treating HIV/AIDS in low-income countries: the case of SenegalSince late 2003 in Senegal, voluntary tests, ARVs and CD4 counts have been provided free of charge by the State within the framework of public health services. Debate now focuses on expanding free access to other compone...

To analyze and gain intuition on the mechanisms of complex systems of large dimensions, one strategy is to simplify the model by identifying a reduced system, in the form of a smaller set of variables and interactions th...

We continue the study of cellular automata (CA) directional dynamics, i.e. the behavior of the joint action of CA and shift maps. This notion has been investigated for general CA in the case of expansive dynamics by Boyl...
