Laser tracking locators have certain drawbacks, among which there is a strong influence of the atmosphere on their energy and precision parameters, the process of aiming a narrow beam at the object, etc. High requirements for locators (the error of measuring the range to a few centimeters) lead to the need to take into account the state of the atmosphere on the route for application Corrections in the measurements. In particular, the phenomenon of refraction leads to a significant distortion of the signal. To reduce the error of distance measurements it is advisable to use methods to compensate for the effect of refraction or to take it into account and use the correction coefficients. The article shows that the effective solution to this problem in the absence of the possibility of obtaining operational and accurate information about meteorological parameters is the use of parallel laser probing of the atmosphere. More promising in this case is the use of laser methods for controlling atmospheric parameters, which we described and experimentally investigated at the Chauda, ​​Feodosiya, and the Republic of Crimea provinces. The obtained atmospheric data were used to create a mobile laser-television locator for external-trajectory measurements of the descent of the aeroelastic systems "Kafa" and were installed both on the ground and on an air balloon. The trajectories of the descent of balloons and cargo parachute systems were studied.

Refraction has a strong influence on the accuracy parameters of the range-finding tract of laser tracking locators and the process of directing a narrow laser beam onto the object. High requirements for locators (the error of measuring the range to a few dozen centimeters) lead to the need to take refraction into account for making corrections to the measurements. Significant distortion of the signal leads not only to the phenomenon of static refraction, but also dynamic. To reduce the error of distance measurements it is advisable to use methods to compensate for the effect of static refraction or to take it into account and use the correction coefficients. The article shows that the most effective solution to the problem of refraction in the presence of a dynamic component is also the use of parallel laser probing of the atmosphere, but it must be carried out at two different wavelengths. In this case, the main method of calculating the correction factors is the dispersion method, which makes it possible to reduce the relative measurement error to 106. The use of laser methods for controlling atmospheric parameters, including two-wave and two-frequency ones, was described by us and experimentally investigated at the Chauda, ​​Feodosiya, and the Republic of Crimea fires on YAG: Nb3 + IZ-25 lasers and continuous lasers . The obtained atmospheric data on the LT-5Z laser were used to create a mobile laser-television locator for external-trajectory measurements of the descent of the aerial systems "Kafa +" and were installed both on the ground and on an air balloon. The flight trajectories of balloons and the descent of cargo parachute systems were studied.

In the article application of the generalized algorithm of processing of the weakly formalized information to a problem of increase of productivity of work of programmers is considered. employees who spend a lot of time on the Internet. It is assumed that the employee of the company works on the Internet during the working day and works with various sites. Sites can, how to treat the work, and not have any relation to the company's activities. It is required to estimate the amount of time an employee spends on websites related to the work of the company and on other sites. The difficulty lies in the fact that there are not enough objective criteria for assessing sites, i.e. this information is weakly formalized. Therefore, it is proposed to apply a generalized algorithm for processing such information. The algorithm contains 14 steps. At the first step, information about the employee's exit into the Internet and connection to various sites is sent to the "Information Collection" module. In the second step, the information enters the "Information Recognition" module. In the third step, the information enters the "Information Classification" module, which refers to one of the types of sites. At the fourth step, in the modules "Convolution of information", information is processed according to a certain algorithm. Next, we evaluate the reliability of the information (step 5), assess the security of information (step 6), establish the links between the newly received information in each of the classes and the information obtained previously (step 7), estimate the probability with which you can trust the information received (step 8). At step 9, decision support is made in each of the classes, and in step 10, generalized support for decision-making. At step 11, a comparison of the recently adopted decision with previously adopted decisions is made, and at step 12 - the development of a stable reaction to the repeatedly received information and its memorization. At step 13, solutions are generated, and at the 14th stage, new information is generated and stored in the vault. Identifies the stereotype of the employee's behavior, i.e. how much time he spends on different types of sites, how reliable it is, how stable is his behavior, whether there is dependence on any kinds of sites, etc.

Energy costs for grain drying are about 30% of the total energy consumption for grain produc-tion. Reducing the energy consumption of drying is possible due to the use of a microwave field. In this case, it is necessary to develop a design of a convection drying zone with a microwave field which will provide uniform drying of the grain throughout the volume. For this purpose, it is advis-able to carry out the simulation of the process. The developed computer model of heat and moisture exchange in the grain layer allows to model one under varying parameters of the grain layer and the drying agent. A computer model implements a stepwise calculation method. According to this method, the grain layer is represented as a series of computer models of the elementary layer. The grain layer is divided into three sections. The specific power of the microwave field is set to con-stant throughout each part. In addition, the model takes into account the features of changing in the specific power of the microwave field in the drying zone from the moisture content of the grain and the distance from the magnetron. The air flow in the microwave convection zone can has an im-portant value for the energy intensity of the process. The paper presents the results of modeling grain drying with two variants of air distribution in the microwave convection zone. Graphs of changes in grain moisture in each of the sections of the layer are given. It is shown that when the air moves from the magnetron, the time and the non-uniformity of drying decrease.

The work is devoted to modeling the dependence of the temperature of the extrusion process in the melting zone on the composition of the feedstock and the rotational speed of the screw shaft. The quality of the finished product can not be determined in real time, but it depends on the values ​​of the technological parameters of the production process. Therefore, the quality of products can be controlled through the control of technological parameters. Therefore, the problem of determining the temperature dependence is an important problem. The model is obtained on the basis of experimental data from a number of alternative models. As parameters, the rotational speed of the screw shaft was used. As a criterion for the quality of the model, the sum of the theoretical model errors from the experimental data is used. As the speed of the screw shaft increases, the temperature of the extrusion process increases with a gradually decreasing rate. The resulting model of the extrusion process can be used in automatic extrusion control systems to control the quality of finished products.

The lack of standards for the calculation of lightweight thin-walled steel structures allowed low-quality producers to save on production, which endangered the people who exploited such buildings. The appearance of normative documents for the calculation of thin-walled structures entails responsibility for the affirmers of these normative documents. In Russia, such norms appeared relatively recently and the purpose of this study was to compare domestic normative methods of calculation with non-significant ones. During the presentation of the study, the concept of a reduced (effective) section of a beam when working on bending was considered. Also, the same stages of the calculation methods were noted, indicating the places where the methods differ in their opinions. The result of this study is a comparison table for the basic geometric characteristic for obtaining the bearing capacity of an effective torque element of resistance. An analysis was carried out and a conclusion was drawn on these values.
