The article addresses the task of automated transcribing of speech signals within the framework of pattern recognition theory. To tackle this task, an adaptation of the decision tree method is proposed in the form of a sequence of tasks of multi-element statistical classification of phonemes in speech signals. The algorithm is controlled by two threshold values that determine the permissible divergence between the investigated and reference signals characterizing the same phonemes in terms of relative entropy metric, and restrict the maximum duration of phonation for the corresponding speech element. Experiments demonstrated both the functionality of the proposed algorithm and its adaptability, provided by the variation of the mentioned threshold values. © 2024 IEEE.

Massive streaming data is the most current technology for storing and manipulating large quantities of data. Processing the substantial amount of streaming data is still a challenging issue. The speed and throughput can be improved while extracting this huge amount of data by using a dynamic query processing technique. The sector-based incremental clustering indexing and scalable deletion approach is used in this paper to improve the system performance. Stream processing can be more effective and flexible by applying dynamic query processing technique. Incremental clustering using sector-based method and scalable deletion which removes unwanted, spurious data is proposed in this work in order to process incoming streaming data effectively. Incremental clustering is one of the clustering methods used for processing dynamic information. It is not necessary to plan the entire dataset ahead of time in this method which is suitable for live streaming data, because it processes one instance at a time. So, less space and time is used. Various queries with different types of datasets executed using sector based incremental clustering and scalable deletion methods. The proposed system achieves the highest results for more than 90% accuracy with less space and more speed when the execution time and data retrieval are empirically increased compared with conventional approaches. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

The work is devoted to the actual problem of control system design for underwater vehicles with a high level of autonomy. The article proposes an asymptotic method for separating motions in conjunction with a probabilistic analysis of a possible deviation from a given trajectory as a result of the impact of random disturbances. Approbation of the method was carried out by simulating an underwater vehicle with two rudders (bow and stern) in the problem of longitudinal motion control at a constant speed at a given depth. As a result, it was shown that if accelerations are formed by fast subsystems, then in slow subsystems it is possible not only to achieve acceptable quality and accuracy over a fixed interval, but also to ensure this regardless of the effect of disturbances. Moreover, in this paper, we present the main relations for controlling deviations from a given trajectory during the motion of a slow subsystem. © 2023 IEEE.

Reinforcement learning-based unknown reference tracking control of HMASs with nonidentical communication delays

This paper focuses on the optimal output synchronization control problem of heterogeneous multiagent systems(HMASs) subject to nonidentical communication delays by a reinforcement learning *** with existing studies assuming that the precise model of the leader is globally or distributively accessible to all or some of the followers, the leader's precise dynamical model is entirely inaccessible to all the followers in this paper. A data-based learning algorithm is first proposed to reconstruct the leader's unknown system matrix online. A distributed predictor subject to communication delays is further devised to estimate the leader's state, where interaction delays are allowed to be nonidentical. Then, a learning-based local controller, together with a discounted performance function, is projected to reach the optimal output synchronization. Bellman equations and game algebraic Riccati equations are constructed to learn the optimal solution by developing a model-based reinforcement learning(RL) algorithm online without solving regulator equations, which is followed by a model-free off-policy RL algorithm to relax the requirement of all agents' dynamics faced by the model-based RL algorithm. The optimal tracking control of HMASs subject to unknown leader dynamics and communication delays is shown to be solvable under the proposed RL algorithms. Finally, the effectiveness of theoretical analysis is verified by numerical simulations.

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.

The paper considers the condition and comparison of representation on the Internet of both unaffected and reformed research institutions, in order to form a methodology for assessing the possibility of adequate and timely response to the enormous social and economic challenges occurring in the world;for this purpose, websites' content condition and dynamics are analyzed using the example of agricultural research institutions based on monitoring thereof in 2017 and 2022. It is shown that the science reform proved itself inconsistent since at first it did not respond to the demands of production during the pandemic, and now to the requests due to sanctions. The result of the science reform was a significant increase in the number of uninformative websites, which contradicts the new social order that all sectors of society, business, and management generate for digital tools for transferring scientific developments to the economy against the backdrop of severe sanctions and the pandemic. © 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.
