sine wave

Sinusoidal waveform A waveform of periodic oscillations–eg, in alternating current in which the amplitude of each point in the wave is proportional to the sine of the time from a start point Cardiology An EKG finding described in severe hyperkalemia where the 'P' wave disappears and the QRS complex and 'T' wave merge in an oscillating pattern

sine wave

(sīn wāv)
A symmetric wave representing one complete cycle of a single-frequency oscillation; the displacement of mass over time described by using a function from trigonometry, the sine.

The upward motion in the first area represents a cosine curve, has the size of a quarter of wave and corresponds to an interval marked as [[PHI].sub.0], (Fig.
The unevenness, the cosine curve mentioned in chapter 6 and 8 of (Thierheimer, 2005) respectively, having 6 cm amplitude and a 0.1 s width, is perceived in the right side of the vehicle with an 0.18 s phase shifting between the two decks, the vehicle's speed for this trial being estimated of at least 20 m/s.
For the analysis of a rhythmic diurnal variation, individual as well as combined raw data and normalized scores were submitted to a computer program (Chronolab 3.0) (24), which fit a single cosine curve to the data using linear regression techniques.
