Parameters of neuromuscular system at the unexercised and trained examinees from a position of the theory of chaos and self-organization are studied. Essential distinction between two studied groups (the trained and unexercised students) is established. Dynamics of involuntary micro-movements of extremities (fingers of hands) in a person as reaction to the dosed physical activity is shown in change of parameters of quasiattractors of characteristics of a tremor. Dynamics of increase in volumes of quasiattractors of a vector of organism state in the unexercised students is revealed. The new technique of research of a control system by movements of a person by means of the analysis of characteristics of a tremor of an extremity in the conditions of physical activity is stated. Practical possibility of application of the method of multidimensional phase spaces of involuntary micro-movement in the assessment of reaction of neuromuscular system of the person on dynamic physical activity is shown. As a measure of state of human neuromuscular system (to loading and after loading) the authors use the quasiattractors of movement of state vector of system in two-dimensional phase space of states.
The results of the stochastic analysis of postural tremor (as alleged involuntary movement) and tapping (as supposedly voluntary movement) are considered in a comparative perspective. It is proved that the stochastic analysis of the results of chaotic dynamics in tremorogramms and tapping does not give significant differences (absence of voluntariness). Typically, all samples are significantly different and it is impossible to distinguish subjects in their tremorogramms or tapingramm. The significant differences between sites of tremorogramms in terms of a normal distribution or a non-parametric distribution are demonstrated. A continuous variation of the distribution function is observed: parametric distribution shifts to non-parametric distribution, but among themselves they (distribution function) are all different. It is well known that the unpredicta-bility and continuing changes in the state are characteristic feature of chaos. The evidence of special kind of chaos in biosystems which differs significantly from the deterministic chaos of Tom – Ar-nold is given.
In the conditions of sanatorium treatment the parameters of the cardiovascular system of schoolchildren with the latitudinal displacements were analyzed. Analysis of parameters of cardiovascular system of children in sanatoria from the position of the stochastics showed that the behavior of RR-intervals is still chaotic. The results of the study revealed that short-term treatment reduces the size of quasi-attractor vector of conditions of the human body and partially normalizes the indicators of the cardio-respiratory system of children. However, after the rest of the distance rX increasing, says lack of formation of mechanisms of adaptation of students, as well as significant tension of regulatory processes. The use of the method of calculation of matrices mega-factory of distances in m-dimensional phase space provides some quantitative evaluation of adaptive reserves of the body. This allows us to objectively assess the dynamics of reserve possibilities of organism and their prognostic significance.
In the agricultural economics literature evaluation of employees of engineering services at various levels is rare. At the same time the importance of this issue is beyond doubt, the article provides one way of payroll employees of engineering services with the performance of their work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
