Authors: Ketova K V , Kasatkina E V , Vavilova D D 
Published: May 2021

Abstract
The paper is presented an effective adaptive forecasting system based on combining mathematical modeling tools, including neural networks and genetic algorithm. The construction of the neural network structure that is best relative to the selected criterion makes it possible to improve the procedure for finding a solution to the problem in terms of a number of parameters. Each individual in the genetic algorithm is encoded as a vector with data on the number of neurons on the intermediate layers of the neural network. The evolution of the population occurs in the genetic algorithm, information in the chromosomes changes as a result of the probabilistic application of genetic operators. As a result, such a structure of the neural network is formed, at which the convergence to a given level of error of 1.0% is the fastest. Applied calculations were carried out on the monthly statistical data of investments in human capital (education, healthcare and culture) of the Udmurt Republic. The proposed adaptive system, applied to the construction of forecasts of socio-economic indicators, can be used in the construction of development strategies both at the regional level and at the country level.

The dependence of the angle of inclination of the element of the hydraulic cylinder rod on the angle of lifting of the supporting structure is obtained and the nature of the dependence is shown. The system of equations was solved in matrix form for the given values of the angle of the hydraulic cylinder rod position.
Reference gage calibration methods of probe nanometry systems
Authors: Antsyferov S S , Karabanov D A , Rusanov K E , Fazilova K N 
Published: May 2021

Abstract
Reference gage calibration methods of probe nanometry systems are considered in this work. Existing methods for calibrating reference standards provide high measurement accuracy, but at the same time are distinguished by a high complexity of practical implementation, in particular, the interferometric method, or low accuracy, but with simple practical implementation. Therefore, the urgent task is to develop a calibration methodology that provides a sufficiently high measurement accuracy with a relatively simple practical implementation. The paper proposes a methodology based on the combined use of two methods: a comparative assessment of the step heights of the calibrated gages using one of the probe nanometry systems and the precision measurement of the step height of one of the calibrated gages by computer three-dimensional reconstruction of images in a scanning electron microscope. The components of the measurement uncertainty arising when determining the height of the steps of the calibration standards are investigated. The calculated value of the expanded uncertainty showed that the achievable measurement accuracy is comparable to the accuracy of the interferometric method with a simpler practical implementation. Practical testing of the proposed methodology has shown that the use of calibration techniques developed on its basis provides high accuracy and reproducibility of the results obtained.

Authors: Lazar V V , Erokhin M N , Vergazova Yu G , Kataev Yu V , Gradov E A 
Published: May 2021

Abstract
The technique and features of micrometering of cylinder liners are presented. The main factors influencing the wear of the cylinder liner and the rules for assigning planes and sections when conducting a micrometer of its inner surface are theoretically substantiated. On the example of a study of used cylinder liners of engines of the Yaroslavl Motor Plant, it was revealed that the greatest wear is manifested in the place where the upper piston ring stops in the upper part of the liner, and the amount of wear will be greater in the swinging plane of the connecting rod due to the action of normal force during pressure distribution at the beginning of the expansion stroke. High wear at the top is also due to high temperatures and lack of lubrication. It was found that the diameter of the upper non-wearing band can be used to judge the initial size of the sleeve hole. The underside of the cylinder liner is subject to wear due to the friction of the piston skirt against its surface.

Authors: Nebylov A V , Nebylov V A , Kuznetsov A A 
Published: May 2021

Abstract
The task of synthesizing an automatic motion control system based on the criterion of the minimization of maximum control error is set. The maximum resulting error is defined as the sum of the dynamic component of the error and the component of the error from the broadband interference disturbance. The task is especially relevant for controlling the landing of aircraft, a wide range of guidance tasks, flight control in the mode of following the terrain, in the mode of stabilizing the low altitude of the WIG-craft. The maximum possible value of the dynamic error is strictly estimated from the given maximum values of several derivatives of the input action. These numerical data are easy to find experimentally or based on a priori theoretical research. As for the second component of the error from the input white noise, its quasi-maximum value is assumed to be equal to five r.-m.-s. values. The objective function of the system parameters optimization is investigated analytically for the extremum. The potential control accuracy is determined. In contrast to optimization by the criterion of minimum r.-m.-s. error, the optimal bandwidth of the system is narrower that is better for suppression the interference error.
