Cosine
Definition:
(n.) The sine of the complement of an arc or angle. See Illust. of Functions.
Example Sentences:

(2) The EMG data were fit with a nonlinear, multiple cosine function, which allowed the identification of one, two, or sometimes three separate cosine peaks.

(4) Data were fit using a two-step sine and cosine regression for each 24-h period.
(5) Diurnal periodicity in bradyarrhythmia (sinoatrial block, atrioventricular block) and heart rate was analyzed by the least square fit of 24-h cosines.
(6) In comparison with APO-UNSUS rats APO-SUS rats showed significantly more spike-wave discharges, especially during the dark period: both the mesor and the amplitude of the optimal cosine fitted to the data were significantly increased, whereas neither the acrophase nor the period length (24 h) differed.
(7) To implement a picture archiving and communication system, clinical evaluation of irreversible image compression with a newly developed modified two-dimensional discrete cosine transform (DCT) and bit-allocation technique was performed for chest images with computed radiography (CR).

(9) The modulation depth showed a close to cosine relation with the angle between the preferred axis and the stimulus rotation axis.
(10) Curvature-increment thresholds were measured for contour curvatures from 0.31 to 10.65 deg-1, for grating spatial frequencies of 4.0 and 16.0 cycles per degree (cpd), and for gratings in either sine or cosine phase at the point of maximum curvature.

(15) A compression technique based on the discrete cosine transform takes the viewing factors into account by compressing the changes in the local brightness levels.
(16) When two drifting cosine gratings are superimposed, they will, under appropriate conditions, form a coherently moving two-dimensional pattern whose resultant direction of motion may either be between (type I), or outside (type II) the directions of the two components.
(17) In the second experiment, DLs were obtained for linear, exponential, and raised-cosine onset envelopes at rise-time values between 10 and 40 msec.
(18) The new nonlinearity hypothesis cannot account for the results obtained with sine-phase test stimuli, though it gives a better account of the results with cosine-phase stimuli than does the early nonlinearity hypothesis which was tested and rejected by Nachmias and Rogowitz (1983).
(19) The gonadotropin secretory pattern was subjected to cosine analysis for identifying rhythmicity.
(20) Two-cosine functions often provided the best fit to the EMG data.
