Photovoltaics in horticulture as an opportunity to reduce operating costs. A case study in Poland
Authors: Lakomiak A , Zhichkin K A 
Published: December 2019

Abstract
Fruit farms can become prosumers - producers of electricity for their own needs, without the possibility of selling overproduction. The subject of the study were the costs of electricity in fruit growing. The paper presents a research hypothesis that reads: Agriculture-Polish orcharding can contribute to an increase in the share of energy produced from renewable sources. The aim of the study was to determine the impact of installed photovoltaic panels on the cost of fruit-growing activities. The research methodology was based on a case study. An orchard farm producing apples and peaches on a total area of 33 ha was presented. The costs of fruit growing were developed and the share of electricity consumption costs was indicated in them. Studies have shown that a return on investment in photovoltaic panels is possible after about 8 years. Energy costs account for around 6% of the cost of an orchard. Installing photovoltaic panels on the roofs of cold stores will reduce these costs by half. The main conclusion of the study is that the costs of electricity consumption can be reduced in Poland as a result of the use of fotovoltaic installations, provided that you receive financial support from the state or other institutions, e.g. in the form of subsidies or exemption from agricultural tax.
Adaptive hybrid climate control in the manufacture of microelectronics
Authors: Aleshkin N A , Aleshkin A P , Petrushevskaya A A 
Published: December 2019

Abstract
The article discusses the procedure for hybrid control of microclimate parameters in a clean room intended for the production of electronics, using a combination of technologies for recurrent estimation and fuzzy regulation. On the basis of the developed procedure, a smooth assessment of the current values of the controlled parameters and compensation control adequate to disturbing influences are provided. The developed technology is designed to provide an increase in the quality indicators of overcoming transient processes, and, consequently, to improve the efficiency of controlling the climate dynamic system during the implementation of the production process for manufacturing electronics with increased requirements for its operational characteristics. Modern information systems are characterized by the rapid development of the capabilities of the used hardware. At the same time, in order to achieve maximum results, the use of artificial intelligence technologies is inevitable, the most effective implementation of which requires adequate consideration of all available information about the controlled production process. In the formulation under consideration, the complexity of the problem is determined by the need to meet mutually conflicting requirements while ensuring specified values of climatic parameters. The specificity of the control problem is determined by the fact that a change (restoration) of the values of one controlled parameter should not lead to a loss of the set values of other climatic parameters. To achieve the described target effect, it is proposed to supplement the procedure of recurrent climate monitoring with a fuzzy logic mechanism when changing values of climatic parameters.

Published: December 2019

Abstract
The processes that occur during the electron beam welding are very complex. The main problem of electron beam welding is obtaining a reproducible cross section of the weld. This place is subjected to rigorous quality control during the welding of thin-walled joints. In particular, it is required to solve the problem of the welded joint optimal formation on the electron beam input/output section. The development of the mathematical models for the electron beam input and output modes, their joint use as a justification for the choice of the latter modes will allow a reasonable approach to the seam optimal formation in the area under consideration. In the framework of this study, the concept of an electron beam input-output control system for a weld optimizing in the electron beam welding process is presented. Within the framework of this concept, it mathematical and algorithmic software have to be developed for electron beam welding of thin-walled aerospace structures in terms of the electron beam input/output. Such approach will improve the quality of formed integral joints, as well as reduce the complexity of setting up the technological process of electron beam welding. It has to be developed and verified the mathematical models of temperature distribution under various modes of an electron beam input and output, models for optimizing input and output modes of an electron beam, and a software system prototype using the obtained models.

Abstract
The article discusses the task of identifying a neural network controller for the installation of rectification of oil refining production. A rectification process research model is used to evaluate the effectiveness of the controller. The control parameters of the rectification process that are used to identify the controller and evaluate its effectiveness are determined. In a numerical study, the possibility of using a neural network controller to control the rectification process is shown. As a basic option for a comparative study, we used a PID-regulator, which is the standard version in production today. The advantage of a neural network controller in controlling processes in the context of the implementation of various target trajectories is shown. The proposed model of a neural network controller can be adapted and used for computer control of the rectification process.

Abstract
In this paper a method of adaptation with hybrid tuning of a robotic manipulator control system with PD controller is considered. The adaptations of the controller parameters and compensating signal are carried out online and independent using modified simplex search algorithms. To increase the performance of the adaptive control system, the values obtained during adaptation process are stored in a database. The database stores these values and the system state, at which they were obtained during the training phase, and in the control phase the database returns the values according to the current state of the system. Efficiency of the proposed methods is verified by simulations. The results show advantage of the adaptive control system with the database.

A vector analysis of the accuracy of individual blocks in the composition of such laser modules is performed. A technique is proposed for calculating the error in positioning a laser beam depending on the number and use cases of blocks and their noncollinear axes in the laser module. Errors associated with the laser module used for private technical design, a set of blocks and their kinematic relationships, are considered. The factors affecting the error in the arrangement of transmission devices in the laser radiation processing zone are established. The proposed methodology allows us to solve both the direct and inverse problems of calculating the errors arising during the arrangement of transmission devices in the laser radiation processing zone.

Authors: Sabirova G A , Safin R R , Galyavetdinov N R , Shaikhutdinova A R 
Published: December 2019

Abstract
Experimental samples of biodegradable composite material based on polylactide and wood filler, subjected to thermal modification, were obtained. When studying the samples a change in such properties as the rate of biodegradation and tensile strength was observed. It has been established that the degree of preliminary thermal treatment of wood filler can control the rate of biodegradation in the material, which can be used in the production of biodegradable packaging. Depending on the desired product life cycle, packages with an adjustable decomposition time can be created. It is found that with an increase in the degree of heat treatment of the filler in a composite material with more than 40 % of polylactide the tensile strength decreases, while with a lower binder content thermal modification has a positive effect on the strength. Also, adding the fillers can significantly reduce the cost of composite material.

Abstract
The main consumers of feed grain include industries such as livestock, pig and poultry. For the organization of proper feeding of animals and poultry, the rational use of concentrated feeds, the main component of which are grain and leguminous crops, providing about 50% of protein, is important. Currently, the share of concentrated feed in the total feed balance is more than a third. The efficiency of using feed grain without prior preparation is markedly reduced. The quality of the crushed feed in its granulometric composition exceeds the quality of the feed crushed by any hammer mill, due to the increase in the content of the easily digestible animal and bird fraction and the reduction of the dust fraction, which has a negative effect on the animal’s body. One of the main ways to prepare grain feed for feeding is grinding. During grinding, conditioning, crushing and other operations, the hard shell is destroyed, the availability of nutrients to the action of digestive juices increases, digestibility is accelerated, and more complete absorption of feed energy occurs. Grinding is the most energy-intensive and time-consuming operation, occupying more than half of the total labour costs in the preparation of animal feed. The article provides the scientific rationale for the energy efficiency of the feed grinding process.

Abstract
The article discusses methods of factor analysis to identify heterogeneity in the conditions of spatial distribution and flow formation in aquatic ecosystems. Various factor analysis algorithms were studied to take into account the conjugate action of many factors. Examples of ranking the established dependencies by the value of their own significance criteria are shown. Deficiencies of factor analysis methods in certain software applications were identified because of a possible incorrect interpretation of the results due to the complexity of the technology. The possibility of using factor analysis tools to describe the spatial structures of hydrological data and identify risk zones associated with the instability of the hydrological regime was identified.
