Published: May 2020

The object for the control system is an electrolysis plant for the production of chlorine, hydrogen and electrolytic alkali by the method of diaphragm electrolysis. It is necessary to develop an improved system for controlling the process of diaphragm electrolysis. To create a control system for the electrolysis process, a fuzzy controller with the following output parameters was developed: the percentage of opening of the electromagnetic valve for supplying NaCl solution to the electrolyzer, the percentage of opening of the actuator for supplying asbestos suspension, the percentage of opening of the control valve for draining NaCl solution through a special device, voltage value. Control output parameters control input parameters: anolyte level and caustic concentration. Controlling of the output parameters is based on the information received from the input sensors of the concentration of caustic and the level of anolyte. The control algorithm modeling is performed in the Matlab package. The programming of the Modicon M340 controller and its connection is made using the Unity Pro CASE system. An automated workstation for controlling the electrolysis process is performed in the Vijeo Citect SCADA system. The introduction of a multidimensional automated control system that controls the entire electrolysis process allowed us to solve the problem posed: optimal control of the process output parameters.

Published: May 2020

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.

The 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.

Authors: Quiroz Cabascango V E , Yu Bazhin V
Published: May 2020

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.

Authors: Kh Kurbangaleeva M
Published: May 2020

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.

Published: May 2020

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.

Published: May 2020

The methodical of proportional-integral-derivative (PID) controllers designing for systems the sixth order are suggested. At the first stage of implementation of the method algorithm, the transfer function of the corrected closed control system is determined. Then you can specify the number and type of roots of this polynomial. The roots of the polynomial are set taking into account the root quality indicators. The next step of the algorithm determines the values of the parameters desired polynomial of the corrected closed system. These parameters will depend on the imaginary parts of complex-conjugate roots. Parameters of the polynomial must be positive It follows from the stability condition of the system. For a sixth-order model, the four higher-order parameters of this polynomial do not depend on the controller parameters and their values cannot be changed, since they are determined by calculations. Next, the coefficients of the PID controller model are calculated. You can set the condition for positive values of the regulator parameters. Checking the results of calculating the parameters of the controller is performed by the step response of the system. The efficiency of the proposed method of the designing PID controller is performed on the example of a system with a sixth order object.

In most practical cases, rotor systems are complicated mechanical objects. In solving a number of problems, such as investigated of dynamics and determining the technical state of elements of a rotor system, it is necessary to measure the spectral characteristics of vibration of some connection joints. As a rule, this is not always possible to do directly and leads to the need for a structural analysis of vibration processes. This analysis includes some questions such as partitioning complicated mechanical system on elementary systems, estimating relationships of coordinates and determination of unobservable parameters by observable. The graph method of connections is one of the most promising techniques of structural analysis. This method determines typical models of the dynamic processes of rotor systems with regard to characteristics of individual elements.

Towards the development of innovative technologies for the «Mobility as a Service» system
Authors: Sakulyeva Tatyana
Published: May 2020

One of the main conditions for the successful operation of the Mobility as a Service system is the ability of smartphones to access various modes of transport. For the first time, the «Mobility as a Service» concept was implemented in the Swedish city of Gothenburg, offering excellent public transport conditions and sustainable urban mobility. The purpose of the transport policy is to support the transport system, which ensures the movement of passengers and goods. «Mobility as a Service» is seen as a tool enhancing travel comfort and developing a safe and reliable transportation system. Public transport is the core of the «Mobility as a Service» system. In connection with the development of the «Mobility as a Service» system, the transport policy of many countries needs to adjust its course so that the development of mobility motivates the use of public transport services and active means of transportation.

The theory and practice of efficient organization the technological processes has significant developments. However, the issues of measuring technological processes and monitoring their execution remain poorly studied. On the one hand, there should be a lot of control points to ensure a timely assessment of the current state of the system, to form an effective management impact to adjust its trajectory. On the other hand, continuous monitoring is too costly, burdens the information system with redundant data. This article describes the theoretical aspects of measuring technological processes and monitoring their performance. The proposed approach to determining the frequency and scale of control procedures is based on the critical principles of rationality and efficiency. It allows you to determine the necessary and sufficient number of control points. Another problem is the presence of a large number of benchmarks, the number of which increases with the development of management theory. This problem is solved by applying universal metrics that characterize any technological process of the company: “work”, “speed”, “time”, “acceleration”. This approach unifies the economic space of measurement, makes it visible and accessible to any level of management, allows for accurate identification of process parameters at any time at minimal cost.

Improving the terms of the life cycle contract for the creation of complex technical objects in high-tech industries
Authors: Ermakova O V , Ruban N V
Published: May 2020

The article discusses the features of life cycle contracts (LCC) for the creation of complex technical objects as a form of public-private partnership (PPP), which is the basis for the development of industries of a modern innovative economy. These contracts are used in the design, modernization, and operation of transport infrastructure facilities, roads and road facilities, airfields, public utilities infrastructure, capital construction, state information systems, and specialized services industries. To improve contractual relations, it is proposed to use the theory of contracts of 2016 Nobel laureates Oliver Hart and Bengdt Holmström, based on the improving information management processes and applying incentive schemes that are optimal for various cases, allowing to take into account the interests of all interested parties and achieve the greatest effect from the execution of the contract. The developed recommendations and proposals are presented to ensure the validity of the cost estimates of the contract stages, stimulate the introduction of innovative technologies, and increase the effectiveness of investments at various stages of the life cycle of the implementation of projects for the creation of complex technical objects. The prospects of using innovative solutions for the use of blockchain technologies are considered.
