MAXIMUM LIKELIHOOD ESTIMATION OF CLUTTER SUBSPACE IN NON HOMOGENEOUS NOISE CONTEXT

In the context of a disturbance composed of a Low Rank (LR) clutter plus a white Gaussian noise, the corresponding LR filters used to detect a target embedded in this disturbance needs less training vectors than classical methods to reach equivalent…

Power cycling aging tests at 200°C of SiC assemblies for high temperature electronics

The reliability of power electronic modules is of utmost importance all the more so since they would be exposed to high ambient temperatures and frequent power cycling. Aging tests at 200°C have been done using power cycling in order to study some…

Mesures d'utilité des composants d'un système dynamique par l'analyse structurelle

L'étude à l'aide de graphes des propriétés des systèmes dynamiques qui dépendent essentiellement de leur structure, permet de résoudre de manière simple et pédagogique de nombreux problèmes d'observation et de commande. On donne un aperçu des…

Hard magnetic properties of melt-spun Mn-Al-C alloys

Structural and magnetic characterization of Mn(x−y)Al(100−x−y)C(2y) (x = {50, 55}; y = {0, 1}) melt-spun ribbons is reported. To obtain the metastable ferromagnetic τ-phase, rapidly solidified alloys were annealed either in a vacuum furnace at 823 K…
