Chu, M. and Lin, W.W. (2009) Quadratic Model Updating with Symmetry, Positive Definiteness, and No Spill-Over. SIAM Journal on Matrix Analysis and Applications, 31, 546-564.

ABSTRACT: In this paper, we consider the model updating problem of the undamped vibroacoustic system with no spill-over (MUP-UVA), which is to update the original system to a new system such that some ...
