This paper presents studies, carried out by Te¿le¿com Bretagne, concerning new radio technologies (mainly WiMAX, 802.16e) in the maritime environment. The aim of these studies is to reinforce the quality and the robustness of such transmissions. Several measurements were set up to characterize the propagation channel in maritime environment in order to(More)
Regulation in time of the toroidal current profile is one of the main challenges toward the realization of the next-step operational goals for the National Spherical Tokamak eXperiment - Upgrade (NSTX-U). In this work, a nonlinear, control-oriented, physics-based model describing the temporal evolution of the current profile is first obtained by combining(More)
The qualification and validation of nuclear technologies are daunting tasks for fusion demonstration (DEMO) and power plants. This is particularly true for advanced designs that involve harsh radiation environment with 14 MeV neutrons and high-temperature operating regimes. This paper outlines the unique qualification and validation processes developed in(More)
