Published: June 2019

Abstract
Downhole artificial lift is the most energy-intensive process at the oil companies. In the current economic conditions, the oil companies are forced to optimize the power consumption for production processes. To do this, you must have a methodology for calculating the energy consumption of all oil-producing equipment. Energy losses occur in all parts of the electrical submersible pump units: submersible motors, electrical cables, transformers and control station. There are analytical expressions that allow finding the power consumption in all elements of the pumping unit. However, the energy consumption depends on many process and operating parameters, such as density, viscosity, water content wellbore fluid, gas content, temperature in the borehole. The authors conducted a study on the impact on the power consumption of various technological and operational parameters. When adjusting the pump performance varies depression and reservoir, respectively, and the oil recovery wells. Therefore, to determine the optimal performance of the pump for the payment by a particular well is problematic. The relationship between the formation and the depression change inflow well fluid can be determined according to well testing. The results of this research can be useful to specialists in the development of the oil-producing enterprises of measures to optimize energy consumption.

Abstract
Off-line differential fertilization is one of the science-intensive technological processes in the precision farming system. The process ensures the change of the norm during the movement of the device in the field in the automatic mode according to the task map compiled on the personal computer for the elementary parts of the field. In the conditions of Western Siberia, studies have been conducted to identify the effectiveness of a differentiated method of applying nitrogen fertilizers for the planned yield of spring wheat of 3.0 t/ha. Off-line implementation of the technological process allows reducing the rate of fertilizers by 7.7-21.1%, production costs by 1.9-3.4% compared to the traditional method. It is shown that the application of top-dressing in off-line mode increases production costs by 10.2%, the rate of ammonium nitrate - 34.4-68.5% relative to the differential application of 4.0 t/ha to the planned yield of spring wheat.

Authors: Sereda T G , Kostarev S N 
Published: June 2019

Abstract
A crucial prerequisite for recycling forming an integral part of municipal solid waste (MSW) management is sorting of useful materials from source-separated MSW. The morphological composition of the waste generated in Russia was studied. Theoretical bases of management of the waste sorting conveyor have been developed taking into account failures such as uneven loading and uneven sorting of waste. The calculation of the waste material balance was based on solving the system of Euler equations and flow control. Control laws are defined to control the flow and density of waste on the conveyor. A relay-contact scheme for automatic sorting of waste to extract various fractions of recyclable waste, such as metal, plastic, paper, glass and organic matter from MSW was developed. The synthesis of a finite state of a machine control system for waste sorting is implemented on a programmable logic device Omron.

Authors: Osovskii Dmitrii I , Sharatov Aleksei S 
Published: June 2019

Abstract
The analysis of operational and constructive methods for changing the power of the main engine working on a fixed pitch propeller has been carried out. To purposefully change the operating mode of the main engine, additional (special) jet action of water on the propeller blades of a fixed pitch can be used. The physical effect of supplying additional water to the blades and its effect on the effective power of the main engine is explained. The mutual arrangement of the propeller load curves of the characteristic modes of the engine when additional water is supplied to the blades is analysed. The additional modes of operation of the main engine, implemented with the help of an additional jet effect, are determined. Purposeful change in power consumption at a constant speed prevents possible overloading of the main engine in case of deterioration of operating conditions. Of further interest is the assessment of the thermal and mechanical tension of the main engine operating in varying operating conditions.

Published: June 2019

Abstract
The paper considers the problems of rent distribution peculiar for modern society. Based on the existing external reports of companies-users of natural resources, information technology and the algorithm for calculating the differential rent, the calculations of the annual rent and its current distribution are presented. It is shown that the lack of transparent statistical and reporting information of the companies of tenants/owners of unique hydropower objects does not allow to determine unambiguously the size of a nature-resource rent, in this case a hydropower rent, and, respectively, to create the fair mechanism of its distribution between the company using natural resources (waterways, rivers), and society for the purpose of formation of sustainable ecologic and economic development of the territory. It is shown that faire distribution of a hydropower rent of the Krasnoyarsk hydroelectric power station will allow to provide sharp decrease in deficit of the consolidated budget of Krasnoyarsk Region and increase in financing of ecological actions.

Published: June 2019

Abstract
The paper presents the results of the experience of industrial wastewater reuse after cleaning from formaldehyde-containing compounds in the water supply system at a woodworking enterprise. The drains after the main stage of mechanical cleaning, cascade precipitators, were additionally settled with the addition of chemical reagents: 5% aluminium sulphate solution, 6% polyacrylamide solution and 10% sodium solution. In this case, the maximum cleaning effect was achieved by 7% higher without the use of reagents. A detailed analysis of the dry residue showed that during the processes of settling up to 28% of the dissolved resins are transferred to the solid phase, and the additional treatment with chemical reagents no longer contributes to the transition of the dissolved resins to a dispersed state. As a modification of the technological scheme of industrial wastewater treatment, two options were proposed that differ in the preliminary preparation of the effluent before evaporation.

Published: June 2019

Abstract
In modern information systems, decision making based on image processing is hampered by the impact of negative external and internal factors leading to image blurring, which introduces uncertainty in this process. In this regard, algorithms and models are used to reduce the effect of uncertainty in image analysis. The article presents a new adaptive algorithm for image processing in different wave bands. The article also presents the results of research on the training of operators of image processing systems in conditions of uncertainty. It is proposed to train the operators of these systems on the basis of a competence-based approach using an information system that allows you to create individual training paths for the operators. The implementation of the training information system is proposed to be made on the basis of a web service.
