We present a simplified model of mechanical behavior of large cantilever arrays with discoupled rows in the dynamic operating regime. Since the supporting bases are assumed to be elastic, cross-talk effect between cantilevers is taken into account. The mathematical derivation combines a thin plate asymptotic theory and the two-scale approximation theory, devoted to strongly heterogeneous periodic...
Stable processes can model the impulsive random noises better than Gaussian distribution in array signal processing. This paper proposes a new FOC-ESPRIT method of 2-D direction finding based on the fractional order correlation and subspace technique for underwater 2-D source localization using a vector hydrophones array. Simulation experiments show that the proposed method is robust in a wide range...
This paper presents a technique for finding design changes which improve the eigenvectors of undamped dynamic systems for which a modal model exists. The designer specifies portions of the eigenvector to be altered and a set of design changes that are reaonable to make. The algorithm then locates the combination of changes that, for the least cost, provides the closest approximation to the specified...
