Multicorrelated stationary random processes/field can be decomposed into a set of subprocesses by diagonalizing their covariance or cross power spectral density (XPSD) matrices through the eigenvector/modal decomposition. This Proper orthogonal [...]

A General asymptotic format is presented for the effect on the modal vibrations of a transverse damper close to the end of a cable. Complete locking of the damper leads to an increase of the natural frequencies, and it is demonstrated that the m[...]

In this paper we develop a general minimum principle of analytical dynamics that is applicable to nonideal constraints. The New principle encompasses Gauss's Principle of least Constraint. We use this principle to obtainthe general, explicit, eq[...]
