A computer decision support system for the design and change-over of production of multi-assortment polymeric materials has been developed. The system helps to solve the problems of choosing hardware design and technological modes of extrusion, ensuring resource saving in production. The system includes a subsystem for selecting the brand of the extruder and assembling a 3D model of the modular screw of the extruder, a subsystem for synthesizing a mathematical model for calculating the extrusion efficiency indices depending on the operating parameters of the extruder, a database of types of polymeric materials, a database of brands of extruders, a database of technological regulations of extrusion. 3D models of elements of screw extruders of various types, rules of placement and layout of 3D models of elements when assembling a 3D screw model, mathematical models of physical processes in the channels of screws and heads of extruders are the core of the system. The system allows you to select the brand of the extruder, form the configuration of the extruder screw and determine the operating parameters of extrusion, at which the specified requirements for the quality of the extrudate, throughput and specific energy consumption of the extrusion are satisfied. Testing of the system has been carried out according to the data of industrial extrusion and calendering productions of multi-assortment polymeric films for packaging food and medicines. The test results have confirmed the operability of the software. They have showed an increase in production efficiency due to a reduction in defective products (non-returnable waste), energy saving, and a reduction in the time of change-over of production on new tasks. © 2023 IEEE.

The computer system for forming compositions and modeling the secondary polymer materials properties is described in the article. The polymer compositions are formed using a customizable dataware, which includes a polymer wastes database and a knowledge base for recycling polymers into useful polymer products The knowledge base is developed using a product-frame model for representing knowledge about polymers and their compatibility. Modeling and research of the secondary polymers properties (strength, elasticity and density) is carried out based on the mathematical models. The result of the modeling system is a technological map for the composite polymer mixture synthesis and the production of a useful polymer product. The map includes data on the recipe, physicochemical and technological properties of polymers as secondary raw materials, polymer composition, hardware and technological design of the process, values of technological controlled variables of individual stages of processing. The use of a modeling system in production makes it possible to reduce the time required to solve the problem of selecting compositions, as well as reconfiguring production for a new task, improve the consumer characteristics of polymer products and reduce defects. © 2023 IEEE.

The article describes intelligent technologies used in the design of an information system for controlling the polymer waste processing into useful technical products. The basis of the system is a configurable information model that includes a database of characteristics of polymer waste and a knowledge base of the processes of their recycling into technical products (containers, packing materials, etc.). The knowledge base is built using a production-frame model for the representation of unformalized knowledge about the polymers compatibility, the quantitative ratio of the components of a composite mixture, waste processing methods to obtain a homogeneous mixture with specified properties (strength, resistance to aggressive substance, etc.). The result of the functioning of the system is the formation of a technological map of the production of a technical product, including information about the formulation and synthesis process of the polymer composition, specifications of the hardware design and the values of the technological modes of the production stages. Testing of the system according to the LLC "Plastic processing plant named after "Komsomolskaya Pravda" on the basis of the Polymer Ecology Training Center of SPSIT confirmed its operability and the possibility of use at polymer industry enterprises. The use of the system allows you to reduce the time spent on solving the problem of reconfiguration of production and selection of compositions, reduce defects and improve the consumer characteristics of products. ©2023 IEEE.

Reliable operation of modern electronic devices is the basis for their effective use. Electromagnetic interference, such as lightning, creates the risk of temporary or permanent disruption of the functioning of device elements. Therefore, it is necessary to take into account the possible consequences of such interference on the basis of prediction even at the design stage of electronic devices. The paper a technique for predicting the magnitude of lightning impulse interference in electronic devices using an artificial neural network is proposed. The advantage of this approach over simulation modeling is that rather complex three-dimensional models and long computation times are not needed. A stand was developed and obtained by measuring the amount of lightning interference in an electronic device. The features of the task of training an artificial neural network based on experimental data are considered. The architecture and parameters of the artificial neural network have been selected. An artificial neural network was trained based on experimental data. The root mean square error between the predicted data and the average impulse interference voltage values on the training data does not exceed acceptable values. The results of predicting the magnitude of lightning interference in an electronic device are presented. If we consider further prospects for using an artificial neural network to predict electromagnetic interference, we can note the relevance of the problem of the impact of electrostatic discharge, intentional short pulse and etc. © 2024 IEEE.

Secure-by-Construction Synthesis for control systems

In this note, we present the synthesis of secure-by-construction controllers that address safety and security properties simultaneously in cyber-physical systems. Our focus is on studying a specific security property called opacity, which characterizes the system's ability to maintain plausible deniability of its secret behavior in the presence of an intruder. These controllers are synthesized based on a concept of so-called (augmented) control barrier functions. We propose conditions that facilitate the construction of the desired (augmented) control barrier functions and their corresponding secure-by-construction controllers. To compute these functions, we propose an iterative scheme that leverages iterative sum-of-square programming techniques. This approach enables efficient computation of these functions, particularly for polynomial systems. Finally, we validate the effectiveness of our results through a case study of a vehicle. © 1963-2012 IEEE.

Outage work planning has been essential to maintain the power grid system. For the operators, the planning is troublesome. It is caused by too complex process. The past few years, we have been developing Outage Work planning Collaboration System (OWCS) with some mathematical optimization techniques. Especially, Security Constrained Economic Dispatch(SCED) is extened in some ways to handle various power grid situations. © 2024 IEEE.

The article presents the results of developing a mathematical model for computer simulation and study of the processes of atmospheric pollutant dispersion, taking into account various factors, including data on known emission sources, meteorological conditions, and monitoring results of pollutant concentrations at specific points in an industrial area. Gaussian and Ermak models were considered as the basic mathematical models for pollutant dispersion. The developed model has been implemented as a computer program that allows for automated simulation iterations based on actual measurements of the environmental situation and weather conditions in a specified area. Calculations and a comparative assessment of the accuracy of the proposed model were carried out using the program, and conclusions were drawn confirming its effectiveness for simulating pollutant dispersion in the atmosphere. © 2024 IEEE.
