Abstract
The present article studies the approach to building the distributed wireless sensor networks. It shows that, for RFID-based wireless sensor networks, the first thing to determine is the field it is intended to be used for, the far or the near one. The operating frequency value determines the size of the antenna, and the correlation is inverse. The operational contradiction analysis shows, that to increase the operating range of the tags, it makes sense to select the systems with an active power supply. But from the energy efficiency perspective, the passive tags are better to be used, and for increasing the range of data transmission, coordinators that collect and transmit the data to the central unit are preferable. Wireless sensor networks technology is the only wireless technology that can be used for solving some surveillance and control issues, where the time of processing of the sensor readings is critical. United into a wireless network with the suggested method, the sensors make up a spatially distributed self-organized system of collection, processing and transmission of information. A special attention is paid to the structural solution for temperature control in the wireless sensor networks elements. In the conclusion, recommendations on using radio frequency identification technology-based sensor systems are provided.

Abstract
Almost in all cases, the hydraulic fluid contains not only the liquid phase of the used oil but also by the gaseous phase, which is often air. Air and oil form a while tanking and pressure drop in particular areas of fluid flow. It can be during dynamic processes due to different rates of gas dissolution and evolution from the fluid. The value of gas compressibility is much bigger than the fluid one, it is necessary to investigate the impact of the gas content of hydraulic fluids on the operation of hydraulic systems. This paper considers analyzing the impact of the gas content of oils on characteristics of hydraulic devices and the properties of hydraulic fluids and the degree of their variation with the amount of undissolved air.

Authors: Bamatov Ibragim M , Bamatov Dzhabrail M 
Published: May 2020

AbstractThe aim of the project was to investigate what is the current and future roles of automation in radiotherapy treatment planning. The existing articles on the topic suggest that currently this area is progressively becoming semi-automated. Where the existing systems estimate what are the desirable dose distributions and suggest certain recommendations as how to achieve those limits of dose distribution. Whereas in the future, many believe that the treatment planning process will become fully automated. From end-to-end starting from the first simulation of radiotherapy and actual treatment itself no human intervention will be present. Although, there are no evidence to state what the treatment planning systems would look like exactly, it cannot be denied that the automation of the process will only be increasing, it is just it cannot be predicted to what degree it will be done so for now.
Nickel oxide reduction in CO/CO2 gas mixtures in reverberatory furnaces
Authors: Quiroz Cabascango V E , Yu Bazhin V 
Published: May 2020

Abstract
This study present laboratory experiments carried out for nickel oxide reduction in a reverberatory furnace at medium pressure and a temperature range of 400˚C-1050˚C. Analyses were carried out on nickel nanostructures and their partially reduced metallic nickel products using Zeiss Leo Supra 35 SEM. It became evident from the experimental processes that the reduction process of nickel oxide under those given pressure and temperature conditions can result in fractionation of a dense layer of nickel from the melt surface which is in association with continuous growth of gaseous pores in nickel oxide. Therefore thermodynamic processes and temperature conditions are regarded as the most important factors which play a fundamental role in the reduction process of nickel oxide (gas-metal, or/and oxide-metal). The results indicate a positive correlation between formation mechanism and the rate of reduction of metallic nickel phases upon inter. Our research took a step-by-step assessment of technological processes and a scientific observation on nickel reduction at chemical equilibrium state of an ideal gas was made, and an account was taken with regards to limitations of variables and melting parameters.
Monitoring the state of water from water source and wastewater by the content of manganese (II) and iron (III) ions
Authors: Kh Kurbangaleeva M 
Published: May 2020

Abstract
The state of the water of water source and wastewater was monitored by indicators of mass concentrations of manganese (II) and iron (III) ions. Studies are based on data from decade (10 days) analyses. Combination of correlation and regression analysis and a time-series analysis method revealed factors leading to appearance and accumulation of manganese (II) and iron (III) ions in wastewater. A mathematical dependence is proposed for predicting the content of manganese (II) and iron (III) ions in the wastewater of soda ash production. By the method of time series analysis, it was found that the content of manganese ions (II) in wastewater does not depend on seasonality, but the content of iron ions (III) has a seasonal nature. The data obtained indicate the need for additional wastewater treatment systematically from manganese (II) ions and seasonally from iron (III) ions.

Increasing reliability of production work personnel when using graphic models of technological processes
Authors: Sh Abyzgildina S , Mazina Z R 
Published: May 2020

Abstract
One of the main causes of accidents at oil refining and petrochemical plants is the human factor. Major accidents at petrochemical plants lead not only to loss of life, but also to environmental contamination. Currently, a complex system of tests and exams is used for staff training. One of the most effective training methods is the use of computer simulators. Unfortunately, the cost of these training systems is estimated in the dozens and hundreds of thousands of dollars. Plants themselves cannot develop such complex information systems on their own due to the lack of relevant software products on the market. A possible solution to the problem of meeting the needs of petrochemical plants is to develop a software platform for creating technological simulators that would meet the explosion safety rules. In this regard, to develop mathematical models of complex chemical and technological systems, a method and program for modeling chemical and technological processes is necessary. To increase the efficiency of calculation algorithms it is proposed to use the method of graphic models.

Abstract
In this article we discuss methods of computing the guaranteed values of the states of a technical system in order to estimate the safety of a technical system. For most models describing the problems of science and technology, it is necessary to analyze the effect of disturbances on the state of an object or system. It is necessary to evaluate the boundaries of the zones of dangerous states and the boundary values of the system parameters. The danger of a system functioning is a threat, possibility, probability of damage, system catastrophe, that is, potential damage to a technical system in certain conditions and situations. An analysis of the boundaries of the safety areas of technical systems helps to obtain quantitative estimates of the possibility of dangerous situations. Used methods are based on the approximation of the shift operator along the trajectory, and taking into account the influence of constantly acting perturbations on the solutions.

Abstract
The most important task of the transition from a raw material model of the domestic economy to a model of high-tech development is the use of modern innovative technologies in high-tech industries. It is necessary to use effective and most appropriate modern unstable business conditions for enterprises to manage their production business processes to increase the competitiveness of Russian enterprises. In the modern innovation sphere, there are many contradictions. On the one hand, Russia acts on the world market as a state with high scientific and technical potential, and on the other, it is simultaneously characterized as a technologically backward country. The annual review of the World Economic Forum states that Russia continues to move slowly down the competitiveness rating of the countries of the world. According to the World Economic Forum report, Russia is in only eight of the ten countries in terms of the quality of state institutions and the ability to generate technological innovations. Analysis of the state of the innovation sphere in Russia indicates extremely low rates.
