In this paper, a novel modal identification technique based on wavelet transform and singular value decomposition (SVD) is proposed. Under the assumption that structural system is time-invariant and the ambient excitation forces are white noise process, structural acceleration measurements from multiple ...

We investigate a flexible method by which we can test the unitarity of the quark flavor-mixing matrix step by step. Singular-value-decomposition (SVD) techniques are used in analyzing the mixing matrix over a broader parameter region than the unitarity region. Unitary constraints let us extract ...

The first step in the analysis is to classify the conformers into groups. Here, Singular Value Decomposition (SVD) was used to group conformations of GBR 12909 analogs by the similarity of their nonring torsional angles. The significance of the present work, the first application of SVD to ...
