This paper presents a refinement of a method that simulates flow- and pressure-regulating valves by replacing them with pipes and adjusting the resistances (diameters) of those pipes to meet the valve settings. The method, referred to as the replacing pipe method (RPM), is readily integrable into the global gradient algorithm, which is the heart of the commonly used EPANET 2 water distribution system modeling software. The RPM proved to be more robust, yet slower than the EPANET 2 valve handling heuristics. In this work, the RPM was modified to increase its computational speed. The modification involved the RPM check valve handling algorithm and condition for updating the diameters of the valve-replacing pipes. The modified RPM was tested as part of a hybrid simulator, which switches from the EPANET 2 valve handling heuristics to the RPM when the former fails. The test networks included a large network with thousands of nodes, pipes, and valves, and a case of an ill-posed problem. As the testing showed, the modified RPM offers a significant reduction in the number of iterations compared to its previous version. © 2024 Indian Society for Hydraulics.

The paper describes the implementation of a software-hardware complex that implements the sorting of objects by colour using computer vision. The algorithm for determining the working area of the robot-manipulator is given. The control action on the executive mechanism is formed by an algorithm implemented in Python using the C3 Bridge Interface, OpenShowvar and OpenCV software libraries for interaction with the robot and computer vision. A Kuka KR4 6-axis industrial robot manipulator with pneumatic gripper is used as an actuator that performs direct object movement. The developed hardware and software system can serve as a basis for creating flexible robotised manufacturers. © 2024 IEEE.

The industrial robot control system solves a large number of tasks that affect the ease of integration and efficiency of the manipulator in the technological process. One of its main tasks is to calculate in real time the trajectory of the manipulator flange movement taking into account the selected type of movement. In particular, this task can be solved using a neural network model. The article describes the solution of the problem of automating the creation of a training set for a neural network model that forms the trajectory of movement of an industrial manipulator. The source of data for the set is a KUKA KR4 R600 manipulator and its digital twin created in the 'Rational Production' software. The training set includes many sets of the manipulator joint angle vectors (generalised coordinates) that uniquely define the current position of the robot and its flange in space. © 2024 IEEE.

This paper presents a method for the robotic sorting of objects in automatic mode, which makes use of the Kuka industrial manipulator. The method proposed in this work performs the segmentation of objects using a neural network, the selection and the determination of the spatial coordinates of the picking object, and the movement of the manipulator and control of the picking device. The results of the tests demonstrated that the proposed method was able to accurately determine the spatial coordinates of the object with minimal error. Furthermore, the Euler angles of the object centre were calculated with an error of 1.73° on the X-axis and 1.77° on the Y-axis. The findings indicate the potential for extending the scope of applications for industrial manipulators. The results demonstrate the feasibility of employing these manipulators in intricate and congested environments, enabling the sorting of object. © 2024 IEEE.

The paper proposes a methodology for creating a dynamic model of a flow heater with time-varying flow rate and heat transfer coefficient. The first-order hyperbolic equation is used as the mathematical description of the heating process. The numerical model of the heating process is obtained using the spectral method of analysis and synthesis of distributed systems. The orthonormal function basis is used for the transition to the state space. A method for the consideration of non-zero boundary conditions is proposed. The state-space model of the flow heater is obtained and its implementation in Simulink using the MATLAB S-Function block is proposed. The results of the study of the obtained model are presented in the article. The dynamic behavior of the model is compared with the analytical solution of the hyperbolic equation. The dependence of the model accuracy on the dimensionality of the state vector is investigated. © 2023 IEEE.

The paper proposes a switching multi-regulator control for an electro-hydraulic servo system with throttle regulation. The architecture of the multi-regulator control, composed of three conventional regulators (PID1, PI2, PI3) for different regions of the setpoint signal variation and switching logic, is discussed. The main issues arising from the use of such control are considered, and an analysis of the stability of the closed-loop system is conducted. Some mathematical formulas and descriptions are presented. Using a universal measurement and control module, graphical results for the quality of the designed control are obtained. The advantages of this type of control and the emergence of additional robust qualities of the system are experimentally proven. © 2024 IEEE.

The method under consideration provides an opportunity to determine the level of preference (LP) of the innovative services in educational institution (ISEI). The method analyzes the collected data to determine how trainees respond to different types of ISEI. The method can be used by educational institutions to improve the ways in which they deliver training and ensure that their methods are effective and meet the needs and preferences of learners. The additional capabilities of the method to predict and assess changes in preferences towards ISEI allow for a more accurate decision. The analysis can be useful to identify the most popular and effective ISEI and how they can be used to improve the learning process. It can also support optimal decision-making by the management of an educational institution. With some minor modifications, the presented method can be adapted to determine the LPs of individual resources, technologies and approaches in different spheres. © 2023 IEEE.

Developing an automated examination timetabling (ET) in a higher education institution is a complex multi-criteria task. To automate this process, it is first necessary to create an algorithm for compiling the ET. When compiling a ET in a higher education institution, the organization of studies in the institution itself must be considered. In this paper, a flowchart of an algorithm for compiling an automated ET in a higher education institution is presented. Automating the process of ET compilation, based on this algorithm, will lead to a higher quality of training. If all the requirements and constraints of ET compilation are met, then one can also argue for satisfaction with ET compilation. In addition to this, finding optimal solutions in composing ET in the future can lead to a higher quality of composing ET, an increase in the quality of learning and to a higher satisfaction of the main agents (students and teachers). © 2023 IEEE.

This work presents the factors that determine the degree of intelligence of artificial intelligence (AI) systems. A methodology for determining the degree of intelligence of AI systems is proposed. The concepts of intelligence quotient of artificial intelligence systems (AISIQ), average level of intelligence of AI systems, and correction factor for the age of an intelligent AI system, are defined. Determining the degree of intelligence of AI systems will allow assess the ability of an AI systems to perform tasks that normally require human intelligence. This can be useful for evaluating the efficiency and reliability of the system and for identifying areas where it can be improved. Determining the degree of intelligence of an AI system can help in decision-making for implementation in various fields, as well as in assessing the potential risks and benefits of its use. © 2023 IEEE.
