Wave theory of movement is used to study the mathematical model of a physical system which describes oscillations of a one-dimensional elastic body under the impact of a moving continuous flow of a homogeneous environment. This model accounts for nonlinear elastic properties of the body at transverse oscillations, as well as environment density and movement velocity. Oscillation amplitude and frequency variation laws in nonresonant modes and under the impact of harmonic perturbation are obtained. Variation laws of the aforesaid parameters are defined by geometrical characteristics of the elastic body, physical and mechanical properties of the material, the velocity of the moving environment, the angular velocity of elastic body rotation, and external factors. © Springer Nature Switzerland AG 2020.

Data poisoning attacks, where adversaries manipulate training data to degrade model performance, are an emerging threat as machine learning becomes widely deployed in sensitive applications. This paper provides a comprehensive overview of data poisoning including attack techniques, adversary incentives, impacts on security and reliability, detection methods, defenses, and key research gaps. We examine label flipping, instance injection, backdoors, and other attack categories that enable malicious outcomes ranging from IP theft to accidents in autonomous systems. Promising detection approaches include statistical tests, robust learning, and forensics. However, significant challenges remain in translating academic defenses like adversarial training and sanitization into practical tools ready for operational use. With safety and trustworthiness at stake, more research on benchmarking evaluations, adaptive attacks, fundamental tradeoffs, and real-world deployment of defenses is urgently needed. Understanding vulnerabilities and developing resilient machine learning pipelines will only grow in importance as data integrity is fundamental to developing safe artificial intelligence.

The article is devoted to the development of means for recognition of the emotions of the speaker, based on the neural network analysis of fixed fragments of the voice signal. The possibility of improving recognition tools through the use of a convolutional neural network of the GoogLeNet type is shown. The expediency of training the network on the examples of the TESS database is determined. A procedure for representing a voice signal in the form of a square grayscale image has been developed. Based on the use of the specified database, the modification of the GoogLeNet network was carried out. The architecture and software implementation of the recognition module have been developed. With the help of computer experiments, it has been established that after 150 epochs of training on a fairly limited training sample, the modified GoogLeNet makes it possible to achieve an accuracy of recognition of the speaker's emotions of approximately 0.97 on test examples. The obtained accuracy is comparable to the accuracy of the best modern systems of this purpose and confirms the promise of using neural network models like GoogLeNet for emotion recognition based on voice signal analysis. The need for further research aimed at reducing the resource intensity of the neural network model is shown. © 2022 IEEE.

The paper contains threshold results and demonstrates a perspective for ongoing research in the field of digitalization of the economy. The relationship between the knowledge economy and intangible and material production is presented. The value of knowledge as a factor of production and goods, as well as a production asset and a production resource is determined. Evolutionary changes in the paradigm of knowledge management in connection with the transition to a new economic formation – the digital economy are outlined. The results of research of the concept and structure of intellectual capital on the basis of a systematic approach are summarized. The problems of both theoretical and applied nature that prevent more effective implementation of the results of the research in the practice of organizations in all spheres of the economy are systematized. The problems are presented in the context of considering the role and place of knowledge in the formation and increment of intellectual capital. The greatest development was the question associated with the development of a model describing the process of increment of intellectual capital through the change of parameters included in the model of describing the increment of knowledge acquired (produced) by the subject of the economy. The perspective direction of research of mutual influence (correlation) of parameters of increment of knowledge and reflecting influence of these parameters on volume and rates of increment of intellectual capital is specified. The methods of mathematical modeling are indicated as tools for the research. This will not only describe the process of increment/change in the volume of intellectual capital using a finite number of parameters, but also explore the possibility of manipulating parameters. The results of the study stated the establishment of mutual correlation with changes in the parameters of the studied processes at various scales. It will allow to form the forecast of behavior of

The problem of forecasting long sequences is important in many different domains. Proper selection of the hyperparameters when a machine learning approach is applied could make the difference between adequate and inadequate model. Several algorithms for automatic hyperparameters tuning were evaluated and compared with baseline selection. As a result, recommendations have been made. Some of the intuitive assumptions for the baseline model proved to be wrong.

Following for hygiene and sanitation requirements have always been the most significant factor to stay healthy in human life. Proper cleaning and sanitation measures are one of the important ways to fight against various viruses. In recent years, the use of modern technology in sanitation has helped to fight against infectious diseases. One such modern technology is disinfection robot. Disinfection robots are increasingly used in all around the world. Use of these disinfection robots reduce the risk of infection, cost of traditional cleaning and disinfection, and most importantly acquires confidence and security of individuals. In this paper, we design a model for robot-disinfector. This robot is inspired on/from a technique, which consists of disinfecting places autonomously in order to save human life from infections. The main advantages of the designed robot are the novelty, multi-functionality, and the availability at an affordable cost. © 2020 IEEE.

Variational quantum algorithms are viewed as promising candidates for demonstrating quantum advantage on near-term devices. These approaches typically involve the training of parameterized quantum circuits through a classical optimization loop. However, they often encounter challenges attributed to the exponentially diminishing gradient components, known as the barren plateau (BP) problem. This work introduces a novel optimization approach designed to alleviate the adverse effects of BPs during circuit training. In contrast to conventional gradient descent methods with a small learning parameter, our approach relies on making a finite number of hops along the search direction. The optimization search direction, together with the range of the search, is determined by the distant features of the cost-function landscape. This enables the optimization path to navigate around barren plateaus without the need for external control mechanisms. We have successfully applied our optimization strategy to quantum circuits comprising 16 qubits and 15000 entangling gates, demonstrating robust resistance against BPs. Additionally, we have extended our optimization strategy by incorporating an evolutionary selection framework, enhancing its ability to avoid local minima in the landscape. The modified algorithm has been successfully utilized in quantum gate synthesis applications, showcasing a significantly improved efficiency in generating highly compressed quantum circuits compared to traditional gradient-based optimization approaches. © 2024, CC BY.
