of RRi were transferred using an infrared interface device to the Polar Precision Performance SW software v.
The results obtained during the study show that there is a need to create an automatic control system using a speed controller that more accurately worked out the given tachogram
, as well as optimization of train driving modes.
The evolution of the tachogram
is plotted on the phone display and the test results are finally shown and stored in a local database.
The 24-hour NN tachogram
showed peaks of turbulence onset and rebound effect of slowing down in both groups 1 and 2, which was found to be statistically significantly different as compared to controls (p<0.005).
A representative tachogram
from an FA-exposed control mouse and an iron-soot-exposed mouse recorded during the first 24 hr after 3 days of exposure are shown in Figure 2.
The recommended sampling time (tachogram
) for HRV analysis is 5 minutes, (48) but different time windows were selected by different authors-5 minutes, 10 minutes, 15 minutes and 24 hours.
RR and systolic pressure sequences were resampled at 4 Hz using the method described by Berger  to give an RR interval tachogram
and systolic pressure systogram sampled at regular intervals.
Temporal series from the tachogram
were related to each selected segment, and were quantitatively evaluated considering the values for the HR, total, and normalized (nu) powers.
HRV assessed using the RR tachogram
, depicts the ability of the heart to respond to various perturbations, and reflects the status of ANS.
On the basis of multiple targeted simulation taking into account the nature, size and mode of operation of load in a certain range of control is carried out design (structural and parametric optimization) special controlled asynchronous motors with different formulations of the problems (designing a predetermined control range, design, taking into account the duration of the work on specific speeds, projecting a predetermined tachogram
1: The Tachogram
. R-R interval data are represented on a tachogram
, in which the y-axis plots the R-R intervals, and the x-axis the total number of beats.
Briefly, each tachogram
was first filtered using an automated beat rejection and interpolation algorithm.
