Entropy approach in the estimation of parameters of cardio schoolboys at latitudinal

Abstract

Options cardio demonstrate the instability of the distribution function f (x) for different time intervals of measurements Δt. We postulate that such systems can not be attributed to the traditional chaotic systems, as for them it is impossible to calculate the autocorrelation function, Lyapunov exponent, no mixing and performance properties of continuous state vector x (t) demonstrates the chaotic motion in the form dx / dt ≠ 0. Since the initial state x (t0) can not be repeated arbitrarily for such systems, there is the uncertainty of the 1st and the 2nd type. Entropy approach is proposed for describing the assessment of the behavior of cardio when changing climatic zones. Compares the value of the results of quasi-attractors samples cardio area and the values of the Shannon entropy. The examples of such a situation for the parameters of cardio groups of children at Ugra latitudinal displacements. It demonstrated that the entropy approach has a low diagnostic value in the evaluation of samples of cardio.
