(5) Previous research only discusses the concept of numbers without analysing the harmonic ratio and addressing the beauty of God.
The U1240C Series ships with unique features such as ZL0W and harmonic ratio. ZL0W is a low-impedance mode to eliminate stray voltages.
Harmonic ratio (HR), i.e., the ratio between the sum of the amplitudes of the two main even harmonics and the sum of the amplitudes of the two main odd harmonics for the AP and CC axes or the reverse (odd/even) for the LL axis calculated via the discrete Fourier transform, which is an indicator of the rhythmicity between acceleration patterns and step repetition, with higher values corresponding to more harmonic gait [13].
The descriptor comprises of two components: harmonic ratio and upper limit of harmonicity.

We also computed the harmonic ratio (HR), a measure of the smoothness of movement and gait rhythmicity [1,4].
Both models offer internal memory; a built-in switch counter; harmonic ratio, dual/differential temperature, and manual datalogging capabilities; and adjustable backlighting with two intensity levels.
For M = 8 (i.e., H = [1,2,..., 8]), the attractor states are realized by the harmonic ratios Q = ([H.sub.i+1]/[H.sub.i]) = (8 : 7), (8 : 5), (8 : 3), (8/1), (7 : 6), (7 : 5), (7 : 3), (7 : 2), (7 : 1), (6 : 5), (6 : 1), (5 : 4), (5 : 3), (5 : 2), (5 : 1), (4 : 3), (4 : 1), (3 : 2), (3 : 1) and (2 : 1).
This experiment investigated the harmonic ratios of human voices that could potentially improve voice synthesis technology.
On the other hand, the proportional systems of Renaissance architecture seem at times not unrelated to the multiplication chains proposed here; an example is the way Alberti split up compound proportions i nto the smallest harmonic ratios, e.g., 1:2 = 2:3 + 3:4 = 2:3:4, and so forth; cf Wittkower, 115.
Contrasting the pendulum to the vibrating string, he says, "Harmonic ratios among pendulums .
