By definition, ECG biometric identification technology uses an electrocardiograph machine to record the electric activity waveform generated by the heart during each cardiac cycle from the body surface of a living person. This waveform then provides identification feature points for identity recognition and...
Within mathematical circles, Euclid's proofs could not be refuted almost 'by definition', as Euclid's work was the very model of valid proofs. But outside the scope of arguments that could be validated by extrapolation from Euclidean practices, polemic and disagreement reigned. Regardless of ...
