The system control test bench, fuel equipment of diesel engines. The use of asynchronous motor together with the Converter of frequency allows to create an effective budget system of adjustable electric drive for maintenance of necessary speed asynchronous electric drive depending on pressure. The proposed management system provides the fuel supply pressure-stable, leading to a significant decrease in hydraulic loads of fuel and diesel equipment. The use of frequency Converter reduces the dynamic load on the engine and optimize operating currents, which creates conditions to reduce energy consumption and increase the service life of machinery.
This article presents the methods of analysis of the dynamics of bioelectrical activity of the
flexor muscles of the little finger of his right hand as a reaction to the static force in compression dynamometer,
manifested in changes of the quasi-attractors parameters. The main research methods were deterministicstochastic
methods and methods of the chaos theory and self-organization to describe complex biological systems.
The authors present a comparative analysis of calculating the parameters of the obtained results, in particular,
in the framework of the chaos theory and self-organization - the calculations of the phase plane and their
areas; in the framework of the deterministic-stochastic approach - the calculation of the Shannon entropy. Calculations
are aimed at assessing the level of randomness of the recorded signal. Analysis of the recorded signal and
the evaluation of the level of randomness in a signal of bioelectrical activity of muscles showed that an increase
in the static load quasi-attractors bioelectric muscle activity increases dramatically. The degree of change was
estimated by calculating the parameters of quasi-attractors according to the chaos theory and self-organization.
The changes of state of the system in the direction of increasing the degree of variability in the bioelectric activity
of the extensor muscles of the little finger are demonstrated.
The high efficiency of application of the chaos theory and self-organization in the assessment of the neuromuscular
human system is showed. The obtained results allow to determining the level of the ability of performing
the specified operations under the influence of static loads.
The scope of compartment-cluster theory of biosystems is in modeling of voluntariness (or involuntariness) of postural tremor and occurs due to the changes in external control drives Ud from 1st (supervisor) cluster. In this case, there are variations in the frequency response and autocorrelation functions, which is typical for tremorogramm of postural tremor and in case of Parkinson´s disease. The voluntariness of the tremor may occur only in the change of quasiattractors’ parameters in models (changing dissipation coefficient b), that is observed in changes of phy-siological states in the organism (con sciously).
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.
