The block dynamics are given by: { x ˙ ( t) = u ( t) y ( t) = x ( t) x ( t 0) = x 0. where: u is the block input. y is the block output. x is the block state. The coherence graph displays a statistical relationship between two signals at a given frequency range. The coherence of two signals, x and y, depends on the phase difference between the signals. It is a normalized value, so it does not specify if the signals are in or out of phase or what is the difference between them.

All false positives occurred after 150 minutes at 60 degrees C and are highly unlikely to be caused by contamination; positive template results were rapid and reaction times were similar for the ...

A total response time of less than 100 ms is possible at a sprint start (in males) when the time between the start signal and the first horizontal force or a limit of 25 kg in the horizontal force is used as threshold. Unfortunately, it is not known which threshold in the force signal must be exceeded within 100 ms to trigger a false start ...Auto-correlation of stochastic processes. In statistics, the autocorrelation of a real or complex random process is the Pearson correlation between values of the process at different times, as a function of the two times or of the time lag. Let {} be a random process, and be any point in time (may be an integer for a discrete-time process or a real number for a continuous-time process).As new variants of the COVID virus emerge, there have been concerns that the at-home tests available may not pick them up..
