SVD-Based Digital Image Watermarking Scheme
, 2009 [[abstract]]In the past couple of years, several digital watermarking schemes have been proposed and based on DCT, DFT, and DWT transformations. In this paper, a singular value decomposition (SVD)-based watermarking scheme is proposed. SVD transformation

Acta Crystallographica Section D, EarlyView.Adenylate kinase was used to quantify how experimental parameters influence radiation damage during time‐resolved X‐ray solution scattering (TR‐XSS) at a multipurpose SAXS beamline. The study provides general guidelines for minimizing radiation artifacts in TR‐XSS.Time‐resolved X‐ray solution scattering (TR‐XSS) enables tracking of protein structural ...

Archaeometry, EarlyView.ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Existence of the hyperbolic singular value decomposition
, 1993 The hyperbolic singular value decomposition is defined on a general n × m matrix and an m × m signature matrix pair. It is employed in finding the eigenstructure of any matrix that is expressed as the difference of two matrix outer products.
