This paper presents a novel method for enhancing temporal resolution of thermal image sequences. The proposed approach employs the Kalman filter, which exploits the spatio-temporal correlation of the underlying physical processes and leverages temporal information contained in rows of an image captured via rolling shutter readout, to successfully reconstruct intra-frame sequences. To address the computational complexity associated with large-scale Kalman filtering, we propose a distributed filtering scheme that takes advantage of the neighbourhood relationship in the underlying diffusion process. Simulation results demonstrate the capability of the method in enhancing temporal resolution while achieving acceptable Peak Signal-to-Noise Ratio (PSNR) of approximately 30dB. The distributed Kalman filter offers significant reductions in computational and storage costs, making it highly scalable for large images. © 2023 IEEE.

Any business processes in an enterprise are associated with the need to periodically assess possible risk situations. Today, assessing risks in order to control them is not enough. It is necessary to continuously, cyclically and on an ongoing basis carry out risk management, which has already become an integral part of the management of the organization. However, the complexity of assessing and analyzing events associated with an unfavorable outcome dictates to organizational systems, which include the subject area considered in the work - a cargo port, the need to develop and use tools that allow for a comprehensive assessment of activities from the point of view of possible risks, including the possibility of cognitive evaluation of each of the results obtained. Risks are considered as situations of failure to meet goals, as well as target standards. The developed balanced scorecard (BS) contains a set of goals and indicators that complement them. In addition to this, through multi-level hybrid and scenario LP risk models of a cargo port, logical and probabilistic connections between goals, indicators and risks arising at all three levels of management are formulated. The basis of the ontological model is knowledge about the above-mentioned connections, the integrated use of which through appropriate queries allows you to choose ways to bypass risk situations under the existing specified conditions. The query results form experimental scenarios with a multi-approach simulation model and allow you to obtain quantitative estimates of indicators, goals and risks. Taking into account all available stochastic characteristics, influencing factors, and also based on information about the results of the experiment, the decision maker formulates the values of the parameters of the original organizational system necessary to adjust in order to prevent the development and aggravation of risk events. © 2024 IEEE.

Warehouses are an important logistic component of various companies. Warehouses may have different layouts, equipment and their own features. Optimization of warehouse operations can decrease overhead costs and increase the economic efficiency of industry. The technological process of steel sheet production at a metallurgical company includes two major stages: casting of liquid steel into billets and rolling of these billets on a rolling mill. In order to coordinate the productivity of these two stages and to be able to fulfill orders promptly, a warehouse of slabs (billets) is used. Billets of different parties and steel grades are stored in stacks. The billets are moved to the warehouse for storage and from the warehouse to the rolling mill by bridge cranes. In this paper the problem of optimization of the process of continuous cast billets storage is solved to minimize the number of slab handling operations. The problem is decomposed into two subproblems SLAP (Storage Location Assignment Problem) and CSP (Crane Scheduling Problem). A modified genetic algorithm was applied to solve the problem. Using a simulation model of the warehouse, the efficiency of the algorithm was evaluated using different approaches to take the restrictions imposed on the process of slab handling into account. It is shown that the most effective is the algorithm in which there is no restriction on the placement of stacks of billets belonging to one melting. © 2024 IEEE.

Modern unstable conditions of the market environment dictate the need for transport logistics enterprises to predict possible risk situations in order to prevent them, as well as to develop tools that allow forming management decisions, evaluating the effectiveness of each of them and choosing the most appropriate one, taking into account specific tasks and various influencing factors. As risks, situations of failure to achieve the goals of the cargo port, as well as failure to achieve standard values by the indicators for assessing these goals are considered. Goals and indicators are indicated in the constructed balanced scorecard (BSC). A set of links between goals and indicators for their assessment with risks at various levels of management is presented in the form of a developed multi-level hybrid logical-probabilistic (LP) risk model of the cargo port, as well as in detailed scenario models of this LP model. The ontological model contains all the information about the interaction of elements that affect the onset of risky events, and allows you to select options for exiting a risky situation in accordance with various specified conditions. The simulation model allows, based on the results of requests to the ontological model and the scenarios of simulation experiments developed on their basis, to develop a management decision that allows avoiding risky situations in the longer term, taking into account all available stochastic characteristics and factors of influence. © 2023 IEEE.

The development of digital twins (DTs) of industrial electrical systems is attributed to the need for the reduction of time and material resource inputs during their virtual commissioning (VC). The same problem occurs during renovation with complete or partial equipment replacement and/or control systems. These problems can be efficiently solved by developing object-oriented DTs based on the Simulink Real Time software and using hardware-in-the-loop simulation (HIL). This software is compatible with Matlab Simulink and the Simscape package, which makes it suitable for the industrial usage. The authors suggest a HIL-based approach that helps make a virtual real-time computer model, with process control signals coming from the industrial PLC that controls the real physical object. This problem occurred during the renovation of the horizontal stand electric drives of a 5000 plate mill. The authors provide the flow charts of the electromechanical system and the object-oriented DT. The implementation of DT in Matlab Simulink Desktop Real Time is reviewed in laboratory settings. The authors present the block structures that make up a virtual model of the electromechanical system. The developed DT was used to adjust control algorithms and controllers and study the dynamic modes over a rolling cycle. The adequacy of the processes was tested by comparing the oscillograms obtained with the developed DT and the rolling mill. The authors stress the feasibility of developing DTs on the Simulink Real Time platform using HIL simulation during VC and renovation of complex industrial objects. © 2024 IEEE.

This report reviews an example of acoustic positioning of partial discharges (PD) in the tank of a high-voltage oil-filled transformer. The literature review confirms the importance of PD monitoring and justifies the feasibility of positioning discharge activity centers. The precise positioning of PD sources is required to determine the location of insulation defects. The authors provide brief information on the development of PD positioning methods and note that their practical application has been insufficiently covered in publications. They present the results of electromagnetic and acoustic PD positioning in a 110 kV transformer. Some details are provided on the devices and measurement methods used, including the localization of areas with increased PD intensity using one acoustic sensor and the subsequent center localization through the installation of 4 sensors at even intervals. The authors provide PD signals and defect impulses received from each of the sensors and demonstrate the difference in the registration time of these signals. They explain the principle behind PD center positioning, which is determined considering delays in signal reception. The authors demonstrate the usage of the Inva (Portable) software for the processing and visualization of acoustic positioning results. They note that changes in the propagation rate of acoustic waves in a heterogeneous medium result in the reduced accuracy of results. The authors also outline the prospects of the research into the elimination of occurring defects. © 2024 IEEE.

The article provides the characteristics of the end cable couplings of the closed switchgear 110 kV at the electric steelmaking workshop of the metallurgical plant. The functions of the continuous technical condition monitoring system are substantiated, including continuous temperature monitoring and on-line registration of partial discharges in the insulation. The first function provides monitoring of the operational load, and the second has the maximum sensitivity for diagnosing defect propagation. A functional diagram of the developed intelligent on-line system for monitoring technical condition with digital signal transmission is provided. The choice of sensors and processor unit is justified. The authors consider the temperature control system of high-voltage equipment 'WDM-T', including a wireless sensor and an information receiver. The results of monitoring the thermal regime are provided, the advantages of partial discharge analysis are pointed out. The temperature trends of the end couplings included in the cable line phases are considered. The system is implemented on the closed switchgear 110 kV end couplings, its long-term operation has confirmed the effectiveness of technical condition monitoring. The developed system may be a component of an on-line cyberphysical system for monitoring the condition of high-voltage equipment in the electric steelmaking workshop. © 2024 IEEE.

The sliding mode control has the property of control independence from the characteristics of the unchangeable part of the automatic stabilization system (ASS). In the article, this mode is proposed to be applied to ASS to stabilize the horizontal working plane using two hydraulic cylinders. A model of this ASS has been developed. The paper synthesizes a sliding control law for ASS and simulates ASS operation on MATLAB-SIMULINK. The simulation results indicate that ASS is a stable system and works quite efficiently. © Published under licence by IOP Publishing Ltd.
