In this paper the possibility of using the VCG “Vectorcardiograph” main loop for Biometrics identification is investigated. A test set of 550 VCG contours recorded from 22 healthy individuals measured at different times are used to validate the system. The proposed system uses only the main loop of the VCG contour for identification. Two(More)
A novel series of the title compound 4-(5-arylazo-2-hydroxystyryl)-1-methylpyridinium iodide 6 has been synthesized via condensation reactions of the arylazosalicylaldehyde derivatives 4a–i with 1-methyl-picolinium iodide 5. The structures of the new arylazo compounds were characterized by 1 H NMR, IR, mass spectroscopy, as well as spectral and elemental(More)
