The study concerns the dynamics of the coastal activities of the harbor of Villefranche-sur-Mer. Borrowing the concepts of territorialities (Gunn; Var, 2002) or competitiveness of an aera (Wackermann, 1989), revisited in a historical perspective and development of natural territories (Bessy 2008), it explored the problem of the littoral development in the light of its past activities. Three periods succeed each other from the international trade stop, then from the military presence to the current tourist vocation leading to its “sportivation”, especially in connection with the development of a local nautical offer. The articulation of these three periods determines the multiplicity of contemporary offerings which also involves the communities in a sustainability policy (sustainability of the sporting offer and protection of the marine biotope) through partnerships both scientific, National Center of Scientific Research (C.N.R.S.), and associations like A.I.D.A. (International Association for the Development of Apnea).

The work developed in this paper deals with control of a linear switched reluctance motor (LSRM). The studied actuator is used to motorize a syringe pump in biomedical systems. A model of the actuator is performed neglecting magnetic saturation. Different control and command modes using standard controllers are detailed and tested in this paper. In order to make a constant flow of the liquid in the syringe pump, this paper reports a study of sensor less force and closed loop control of the LSRM with a classical PID and hysteresis controller.

The rotational speed of a wind turbine is very low compared to that of classical generators, a speed multiplier is then necessary. To eliminate this last, research was directed towards the design of new structures of generators called direct drive (without a speed multiplier). The synchronous and especially asynchronous machines still dominate the market of the wind applications. However, the Switched Reluctance Generator or SRG is regarded as a serious alternative to the traditional generators thanks to its multiple assets (robustness, simplicity of construction, low cost, high torque...). In this work, it is intended to model and simulate a switched reluctance generator 6/4 (SRG) (6 poles with the stator and 4 poles with the rotor) of a power of 30 kW. The design is carried out by finite element method (Software Mag.Net). The modeling and the simulation of this system are carried out under Matlab/Simulink environment.
