MODELING OF THE ASYMETRICAL SHAFT HEATING EFFECT INFLUENCE ON ITS TRAJECTORY IN THE JOURNAL BEARING Boris Grigoriev, Alexander Fedorov
The article is devoted to the analysis of an asymmetrical shaft heating influence of an unbalanced shaft on a tra-jectory of a synchronous whirl in the cylindrical bearing. The mathematical model including both the thermohy-drodynamic analysis of bearings and the analysis of the asymmetrical shaft heating influence on its trajectory is developed. The scheme of the numerical solution of the equations in the model is constructed. The system con-sisting of a shaft with two bearings and the overhung disk was considered as an example.

Approach based on harmonic disturbance compensation with unknown frequency, exciting on linear control object, is proposed. A disturbance rejection task for linear object with any relative degree is considered in this work.
APPLICATION OF FIELD SEPARATION TECHNIQUE ON QUADRUPOLE LENS FINITE ELEMENT MODELING Mikhail Royak, Alexandr Ignatiev, Maria Korsun
Application of variational and finite element statements with two scalar potentials for solving three-dimensional magnetostatic problems with field separation are described in this paper. The use of this approach is illustrated by the sample of quadrupole numerical simulation.
THREE-DIMENSIONAL SIMULATION OF SELF-GRAVITATING GAS Vitaliy Vshivkov, Igor Kulikov
Analytical dependences of rotating self-gravitating gas as a result of nonstationary processes three-dimensional modeling in the gravitating gas system with a self-consistent field are received. Numerical realization of the model of unstable 3D processes in gravitating gas systems with a self-consistent field in the Cartesian coordi-nates is considered. A modified rotation-invariant fluids-in-cell method for numerical realization of equations of gas dynamics is considered. Results of applying the numerical model in a spatial case are presented.

Data structure mathematical model for automated control systems of enterprise production assets is suggested in the article Problems of technical system condition forecasting are given special attention to. The algorithm of data structure design according to mathematical model is proposed.
STATISTICAL ANALYSIS OF AGE-RELATED CHANGES IN HUMAN NEUROMUSCULAR SYSTEM Renat Yulmetyev, Emil Zinatullin, Sergey Dyomin, Aleksandr Yatsenko
The article deals with the original mathematical method of age-related changes analysis in human neuromuscular system. It is based on the statistical memory effects in physiological time series of the human neuromuscular system. The developed analytical method allows revealing the stochastic features of the force output variability for the different age groups. The comparative analysis of the statistical memory quantifiers points to the significant alterations in the manifestation of the memory effects in human neuromuscular activity during the process of aging. Particularly, the force output variability of the old and older-old people is characterized by more sig-nificant fluctuations and by the weakening of the long-range memory in comparison with the young people’s muscular activity. Besides we disclose the specific features in behavior of the spatial and spectral characteristics that belong to the different age groups of healthy people. Particularly, the distinctive frequencies, reflecting the periodic features in functioning of the human muscular system, are revealed. The developed method is useful for understanding the physical mechanisms, which underlie the process of biological aging.
