The phrase "alteration of speed" is correct and usable in written English.
It can be used in contexts discussing changes in velocity or pace, such as in physics, engineering, or even in everyday situations involving movement.
Example: "The alteration of speed during the race significantly affected the outcome for many competitors."
Alternatives: "change in speed" or "modification of speed".
One source for the differences could have been the fact that most current assays measure a global chemotaxis index that depends on multiple aspects of neutrophil migration, including the fraction of the neutrophil population that are able to move, the alterations of speed, directionality or persistence of migration towards chemoattractant gradients.
(In a canon, one melody is derived from another. It may be identical, as in a round, or it may be given various alterations, as of speed, or metre or omission of certain notes).
On this foundation a bowler may elaborate with variations finger spin (in which the ball rotates on its axis as it moves towards the batsman), swerve (which describes a ball that curves towards or away from the batsman once it has bounced on the pitch), alteration of pace (the speed of the ball)—that lend deceptiveness and uncertainty as to exactly where and how it will pitch.
We analyzed the individual movements of RPE1 cells seeded at low concentration (to prevent alteration of trajectories or speed by one cell encountering another one on its way).
The re-tapping-length was significantly shorter (t(17) = −2.190, p < 0.05) for reproduction phases following high EEG-vigilance stage A compared to the lower EEG-vigilance stage B. These findings support the hypothesis of a varying time perception and of speed alterations of the internal clock after different states of EEG-vigilance, which were automatically classified by VIGALL.
In kinesis, as previously explained, an animal's body is not oriented in relation to a sensory stimulus; rather, the stimulus causes an alteration in speed or direction of movement.
The errors that occur in aircraft and small, fast vessels during alterations of course or speed can be avoided by mounting the compass on a platform kept horizontal by a gyroscope.
Linear extension algorithms are designed for both course alteration and speed reduction to keep clearance of all the target ships that own ship should avoid.
This reduction of speed discrimination sensitivity might result from the fact that distance-independent contrast alteration is seldom encountered in real life.
It performs as hyperelastic material under low speed conditions and its stress strain curve changes along with the alteration of loading conditions, with high velocity loadings.
