This paper deals with the analysis and simulation of a Tunisian Wind farms in Sidi-Daoud, the most important wind farm in Tunisia. In this farm constant speed wind turbines are used. The first section devoted to the presentation of the wind farm of Sidi-Doud. In the second part, we present the aerodynamic model of the wind turbine and the transient model of(More)
Braid groups and mapping class groups have many features in common. Similarly to the notion of inverse braid monoid inverse mapping class monoid is defined. It concerns surfaces with punctures, but among given n punctures several can be omitted. This corresponds to braids where the number of strings is not fixed. In the paper we give the analogue of the(More)
