  • Determination of management parameters for the revision of priority public transport passage

    The article deals with the priority passage of regulated intersections by public transport using the method of extending the permitting signal. The relevance of the problem under consideration is due to insufficient study of the issue of choosing the optimal control parameters for the method of extending the resolving signal. Using simulation modeling, a study was carried out of the priority passage control process on two- and three-lane road sections. In the course of the experiment, the dependences between the extension time of the allowed signal and the cycle duration were determined at different ratios of the phase coefficients, as well as the optimal distance of the priority activation detectors. The obtained results of the research work can be used in the design of the urban intelligent transport system and when adjusting the control modes in the automated traffic control system of the urban agglomeration.

  • Algorithm for conceptual design of an object monitoring system with a collaborative multi-agent robotic system

    The issues of modeling the interaction of humans and robots in a common operating environment are considered in order to select the optimal parameters of such a system. The context of the application of multi-agent robotic systems (MRTS) is the monitoring of a fire hazardous area. The homogeneous MRTS includes unmanned aerial vehicles (UAVs) that cyclically perform operations of flying around their area of ​​the territory (with identification of fires) in an autonomous mode, returning to the charging base, waiting for charging, charging, returning to their area of ​​responsibility, flying around their area, etc. etc. An operator works in the charging area, to which the UAVs should not approach less than a certain distance. The system is presented as a multi-channel queuing system (in the charging area). A simulation model is constructed that allows, according to the data of many runs, to construct polynomial regression dependences of the quality indicators of the MRTS operation on its parameters, by which to solve the multicriteria problem of choosing the optimal parameters of the MRTS charging terminal.

  • Monitoring of ice and frost formations on the AC contact network

    Currently, Russian Railways are characterized by an increase in the weight of trains, an expansion of the fleet of sections with high-speed movement of electric rolling stock. All this leads to a complication of the operating modes of the power supply system, increased liability and possible damage from idle trains. At the same time, monitoring systems of the contact network, as an element of the power supply system that does not have a reserve, are of particular importance. On a significant number of sections of the Russian Railways, the wires and cables of the contact network are subject to ice and frost formations and, as a result, serious operational risks and costs. Minimizing the damage caused by the formation of ice and measures to eliminate it is possible if it is detected at the initial stage. The article provides an assessment of the possibility of using systems based on changes in the weight of wires for the purposes of early detection of ice and frost formations.

  • Improving the economic efficiency of conducting cost expertise in the restoration of real estate after a fire

    The article deals with the forecasting of direct material damage to urban areas depending on the number of fires based on official data of the Ministry of Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters, presented in state reports on the state of protection of the population and territories of the Russian Federation from natural and man-made emergencies for five years, based on the model of correlation analysis, which allows us to determine the degree of mutual influence of the parameters under consideration and the linear regression responsible for determining trends for subsequent years. The analysis of the reasons associated with the lack of the possibility of assessing the damage resulting from the fire of the structures of the building or its premises and its subsequent extinguishing in order to increase the economic efficiency of the cost examination during the restoration of real estate is an auxiliary basis for the construction of a correlation-regressive forecasting model.

  • Development of a method for quantum color transformation and calculation of the negative of a quantum image

    This article examines the implications of the application of quantum computing in the field of image processing. A basic conversion associated with gray level processing, such as an image negative, is considered. The article shows how this operation can be expressed using quantum formalism. Whether quantum image processing (in some aspects or some specific applications) has an advantage over classical image processing in realistic scenarios remains to be seen. This depends on solving a number of problems, some of which are unique to quantum image processing, such as feature extraction of a quantum image. Some of them are common to quantum algorithms, such as noise processing. Identifying one of them will significantly speed up the study of this field.

  • Simulation of optimal management of the national park activities

    The continually increasing rate of human economic activity leads to changes in many natural systems. Their restoration is one of the most important tasks today. For this purpose, protected areas have been created, such as natural reserves, national parks, and wildlife sanctuaries. National parks are of particular interest, as they are the only protected areas listed above where tourism is allowed and organized. However, their activities cannot exist without sufficient financial support. This article describes a two-level optimal control model of the national park activity. For the purpose of exploring and analysing the proposed model, an algorithm that can be used to find the Stackelberg equilibrium guaranteeing the sustainable development of the national park is proposed and implemented in software.

  • Means of relay protection and automation state and prospects

    This article uses the structural-functional method. The proposed study shows how many factors influence the performance, efficiency of enterprises and how important it is to follow the latest technologies and vectors of their development. Everything is important, from the material and technical equipment of personnel to the timely replacement of obsolete or outdated devices that have reached the limit of their own reliability. No reliance should be placed solely on technical means or personnel performance - these two crucial aspects must work together, be continuously monitored and have everything they need to perform their tasks in a quality and timely manner. It is also important to learn from the experience of previous years, so that it is possible to understand what mistakes have been made and, therefore, to act appropriately in order to avoid them again. It is also important to develop such positive trends as the transition to remote control of relay protection devices. To date, we must pay special attention to information security of the complexes' operation during the transition to remote control, as the current realities of work at power facilities require exactly that. Equally important is the purpose of this article to forecast future trends in RPA development over a period of twenty years.

  • Modeling and optimization of the sulfate regime in the technological process of extraction phosphoric acid production when the load on the apatite extractor changes

    Mathematical modeling and optimization of the process of controlling the sulfate regime when the apatite load changes on the phosphoric acid extractor is considered. It is shown that the preservation of the "sulfuric acid/apatite" ratio with a sharp change in the apatite consumption leads to a violation of the technological regulations for SO3. The algorithm of correction of this ratio in the transition mode is developed, which minimizes the probability of violation of the regulatory indicators. A variant of implementing the optimal apatite load correction procedure using stand-alone scenarios is proposed. The results were confirmed during the simulation.
