The article is devoted to the development of a method of structural optimization of the functioning of the transport system of robotic vehicles for the processing of containers and cargo in the port based on the modification of the method of branches and boundaries. The relevance of this article is explained by the fact that about half of the volume of all international transportation is carried out by sea transport, and the efficiency of the operation of port transport systems depends on the productivity of their processing in ports, considering. and customs clearance and direct control. One of the most effective technologies for building such transport systems is the use of robotic vehicles, which ensure the transportation of containers and cargo along technological routes in a continuous mode with the possibility of dynamic scanning and detection of prohibited cargo. Therefore, the development and improvement of optimization methods of robotic transport systems for port cargo handling is an urgent applied problem. The purpose of this article is to develop an algorithm for the structural optimization of the robotic transport system for ensuring the transportation of goods and containers along the technological routes of their port processing based on the modification of the method of branches and boundaries. In accordance with the proposed approach, the cost minimization function for the formation of the structure and functioning of the elements of the transport system is used as an optimization criterion. In the process of searching for the optimal version of the structure of the transport system, the method of branches and boundaries is used, in which the principle of possible options is used to divide the current set of solutions of the problem into branching subsets. For subsets of branching, lower estimates of the values of the objective function of choosing the optimal model are calculated. As a condition for the exclusion of inefficient options and termination of branching for the structural optimization problem, the condition for ensuring the maximum possible productivity of transportation by selected robocars with a lower cost is defined. According to the results of the conducted research, it was found that the developed algorithm allows to determine the optimal structure of the robotic transport system, which, under the condition of its minimum cost, ensures the maximum possible productivity of cargo and container processing in the port. At the same time, the proposed approach allows generalization for the case of building the optimal structure of the transport system with maximum productivity and minimum possible cost.

The work is devoted to the creation of an information system for recognizing voice commands based on artificial neural networks. With the development of computer systems, it is becoming more and more obvious that the use of speech recognition systems will be greatly expanded if it becomes possible to use human language when working directly with the computer, and in particular, it becomes possible to control the machine with a normal voice in real time, as well as input and output information in the form of ordinary human language. One of the promising ways of organizing human-machine interaction is the transmission of user instructions to the computer system in the form of language commands. Voice interface is a necessary component when it comes to creating comfortable living conditions for people with disabilities. In the paper, the approaches to the selection of informative features describing the speech signal are defined: the method of linear prediction and spectral analysis, the structure of a neural network with one feedback is considered, and it is established that the learning of the neural network is carried out by successive presentation of the training sample, with simultaneous adjustment weights according to a specific procedure until the tuning error across the set reaches an acceptably low level. The value of the obtained results lies in the improvement of a new method of speech recognition, which is better adapted to the user's speech, which requires a minimum of resources and the creation of an information system with the possibility of voice control using devices based on various operating systems. An informative cross-platform application with a voice interface was designed based on this approach.

EVALUATION OF DISTRIBUTION DENSITY: THREE MAIN APPROACHES

N. I. Boyko, D. S. Chornobay — Mon, 18 Dec 2023 00:00:00 +0200

The study conducted a detailed analysis of three main approaches to density estimation: non-parametric, parametric, and semi-parametric. The results of this comparison indicate that the effectiveness of each method depends on the specific context and characteristics of the input data. The research included an analysis of the methods and the environment used for density estimation. An important step was defining the set of input data used for comparing the methods, which could involve selecting a specific dataset and setting parameters influencing the research outcomes. For the comparative analysis, training was implemented, and models were built for density estimation using each of the chosen approaches. Libraries such as seaborn, numpy, pandas, matplotlib.pyplot, sklearn.datasets, sklearn.model_selection, and scipy.stats were employed to provide necessary tools for efficient implementation and visualization of results. The analysis involved calculating the average density and quadratic error for each type of iris on the selected data, allowing the determination of the effectiveness of each method for a specific class of data and the selection of the optimal approach. The study also considered important aspects such as the statistical significance of the obtained results and the robustness of methods to random anomalies or outliers in the data. The considered approaches to density estimation underwent testing in various scenarios, including cases with non-uniform data distribution, asymmetric distributions, and a significant number of anomalies. We note that taking into account the context and purpose of the research is important when choosing the optimal method. For example, if accurate reproduction of distribution characteristics is required for further application in complex analytical tasks, parametric methods may be preferred. On the other hand, nonparametric methods can be useful in cases where the data distribution is difficult to approximate by known functions. The research focused on comparing different metrics of model quality, such as mean squared error, to determine how accurately each method reproduces the real data distribution and assess its adequacy for a specific application. The main conclusion of the study is that the density of data distribution significantly depends on the dataset, text characteristics, the estimation approach, and data processing methods used. Therefore, recommendations for choosing methods and approaches to density estimation should be adapted to the specific task and application context.

A SYSTEM TO EVALUATE THE ROBUSTNESS OF AN API UNDER HIGH LOADS

R. G. Zatserkovnyi, V. I. Babych, M. I. Plesha, L. I. Khmilyarchuk, O. M. Shvets — Mon, 18 Dec 2023 00:00:00 +0200

Many modern computer systems extensively use application programming interfaces, or APIs. APIs serve as a bridge between different elements of computer systems, allowing them to communicate, interact with each other, and exchange data seamlessly. Formally, an API is a set of protocols, tools, and definitions that allow different programs to integrate with each other, and provide developers with the ability to access certain software functions or data sets. An important task in the process of developing APIs is to ensure their correct operation under high loads. APIs can have hundreds, thousands, and even millions of users, for whom it is important to ensure the stability, scalability, and reliability of these software tools. A system that has not been reliably tested under high load conditions may fail if a large number of users want to use the same API method or retrieve similar data at the same time. Such a system will also be less resistant to DDoS attacks, a type of malicious hacker attack that "clogs" a computer system with a large number of requests, effectively blocking access to it for legitimate users. This article presents the research and development of a testing system designed to evaluate API performance. The system is based on Locust, an open-source tool for testing software under high loads. The tool is designed to model and analyze the behavior of various applications when facing a large number of users. Our performance testing system uses the capabilities of Locust to thoroughly study the stability of the API system in a real-world scenario. It tests a locally running version of an API in detail by loading it with a so-called "swarm" of virtual users. After this process is complete, Locust collects data on the performance of an API – number of successful and failed requests; minimum, maximum, and average request processing time; as well a detailed report that can be used for further analysis of the results. The data obtained as a result of such an analysis contributes to understanding and, subsequently, improving the quality of API performance, offering valuable recommendations for optimizing application performance and identifying bottlenecks in code.

S. V. Popereshnyak, A. S. Vecherkovskaya — Mon, 18 Dec 2023 00:00:00 +0200

The article investigated the use of artificial intelligence technology. It was determined that for the technology of artificial intelligence and machine learning there is no development of the role of people in the coexistence and use of the capabilities of the system of artificial intelligence and machine learning. We mean the systemic point of view of the interdependence of man and system. However, soon there will be a large number of systems using artificial intelligence technologies to help us with medical treatment, provide reliable transportation and support us in decision-making. It is obvious that the opportunities provided by modern technologies of artificial intelligence and machine learning have both their advantages and disadvantages. It has been investigated that the main advantages of systems with artificial intelligence support are: the possibility of dynamism of the learning process and adaptation, the potential of compatibility, which significantly affects the learning process. The disadvantages include the following: the main problem of artificial intelligence technology is that there is currently no generally accepted approach to implementation. The article analyzes the development of modern artificial intelligence technologies. The main modern solutions for digitalization of computer systems are analyzed. The key problems of the development of this concept and ways to solve them are studied, one of which is the technology of the digital immune system, the prerequisites for its emergence and the current state are given. The interrelationships of the main characteristics of modern digitalization solutions have been studied. The advantages of using solutions based on artificial intelligence in solving a wide range of tasks that arise in real life are analyzed. The theoretical basis for the analysis of recommendations for ensuring cyber security of critical infrastructures based on artificial intelligence is presented. A solution was developed for automatic analysis of LOG files based on AI using the Azure cloud platform and the Airflow user interface. Artificial intelligence and digitization of computer systems are two technologies that have great potential, both are already widely used. The combination of artificial intelligence and digitization of computer systems is relevant, because it can be a way to analyze shortcomings in the application of processes and technologies.

GEORADAR ASPECTS OF SECURITY OF NEAR-SURFACE CRITICAL INFRASTRUCTURE FACILITIES

Yu. S. Tarasenko, Iu. V. Savchenko — Mon, 18 Dec 2023 00:00:00 +0200

A significant part of the existing technosphere of the society refers to critical infrastructure objects, which are obliged to apply modern security and cybersecurity systems with a potentially high level of their realization. The article presents the material devoted to the georadiolocation capabilities of near-surface ground diagnostics from the position of ensuring the safety of underground engineering structures. However, when ensuring such safety by means of georadiolocation, it is difficult to get rid of the high level of ambiguity of interpretation of the obtained data on deep inhomogeneities. It is noted that, even at a priori low level of reliability of the results of conducted studies by means of georadiolocation, they are mostly of qualitative nature due to poor predictability of the heterogeneous nature of the near-surface layers of the earth. In this connection, from the point of view of modelling hypothetical measurements, first of all concerning the receiving and transmitting horn antenna unit, the cognitive method of “black box” was used. Being oriented on ITU-R Recommendations (series P, Radio Wave Propagation) concerning electrical characteristics of the earth surface, it is proposed to replace the parameters of the real environment by its effective values, but for homogeneous soil. In accordance with what impedance parameters of electrical characteristics of the soil are introduced and aspects of matching the antenna system with the probed medium by effective values of its (soil) electrical characteristics are considered, the implementation of which provides an increase in the probabilistic level of diagnostics of the layered inhomogeneous earth surface. The described aspects of the near-surface diagnostics of the Earth by means of electromagnetic deep sounding with a variable set of “lenses of clarified optics”, which are focused on the successful detection of local inhomogeneities, contribute to the realization of a positive trend of increasing the efficiency in the process of solving geophysical problems of recognizing the demasking parameters of research objects, primarily in the field of geological exploration. At the same time, rapidly developing, modern experimental methods, techniques and devices, including theoretical developments, have already come close to the successful implementation of not only geophysical problems of deep recognition with a high level of reliability, but also the problems of GPR radar tomography.

ANALYSIS OF RESERVE POWER SUPPLY SYSTEMS OF RAILWAY AUTOMATION DEVICES

Ya. P. Bekh — Mon, 18 Dec 2023 00:00:00 +0200

the use of signaling, centralization and blocking systems (SCB) makes it possible to increase the throughput and carrying capacity of railways, ensuring safe and uninterrupted movement of trains, and reduces the turnaround time of cars, increasing the speed of passenger and freight deliveries. Automation and telemechanics devices currently used in railway transport, according to the tasks they solve and areas of application, are divided into stage and station ones. Semi-automatic blocking regulates the movement of trains in areas with light traffic. Automatic blocking regulates the movement of trains using track traffic lights installed on the stretch, which divide the stretch into block sections. The indications of passing traffic lights change automatically under the influence of moving trains. The main element of the battery is track circuits, the main purpose of which is to determine the location of trains. Automatic locomotive signaling increases train safety and improves working conditions for locomotive crews. With their help, the readings of track traffic lights are transmitted directly to the driver’s cabin. Automatic crossing signaling and automatic barriers ensure the safety of train traffic when crossing railways at the same level as roads. These devices automatically activate traffic signal devices for vehicles and close the barrier when a train approaches and open it after the train has passed. Station systems regulate the movement of trains in stations and large areas: – electrical centralization of switches and signals – a set of automation and telemechanics devices that provide control of switches and signals of the entire station from one point by the station duty officer; – dispatch centralization is the most advanced and effective means of regulating train movement on railways. This system combines automatic blocking devices, electrical centralization and coded telecontrol and telesignaling systems. It allows you to control switches and signals from one point and makes it possible to concentrate all administrative and executive functions for regulating train traffic at the train dispatcher; – automation of sorting humps – a set of devices that increases the processing capacity of sorting humps. Therefore, ensuring their reliable operation, even in emergency situations, is an important task, and the use of alternative solutions provides economic and technical reserves.

The passenger service system is proposed to include: the construction of customer-oriented service and the use of modern technologies of service and communication with customers for high-quality passenger service by airport and airline personnel. The components of the assessment of service quality at the airport are defined as premises/infrastructure, processes, and personnel, for which a system of assessment criteria has been developed. The assessment of passenger service by the airline is proposed to be carried out in terms of ground service, which includes pre-flight and post-flight passenger service and organization of aviation activities; and passenger service on aircraft board with evaluation of the efficiency of the cabin crew and the on-board product. An extended system of evaluation criteria has been developed for each component. The service system of the production infrastructure of the airport and airlines at the airport includes: services of handling companies, services for the operation and maintenance of the airfield, services for the organization of flight support and air cargo and baggage delivery services. For each component, the types of services that form them are considered.

DEVELOPMENT OF A MATHEMATICAL MODEL FOR OPTIMIZATION OF TECHNICAL AND OPERATIONAL PARAMETERS OF URBAN ELECTRIC TRANSPORT

Mon, 18 Dec 2023 00:00:00 +0200

The article is intended to improve passenger transportation by urban electric transport. An optimization model has been developed, which allows to optimally distribute the available rolling stock along the city routes, which will allow transporting as many passengers as possible, reducing operating costs and increasing comfort for passengers on trolleybus routes in Dnipro. The efficiency of the implementation of this model is analyzed. The importance of the quality of passenger service increases in the context of the formation of a market environment and the development of competition (between individual modes of transport). With the development of the transport services market, the consumer (passenger) has the opportunity to choose the most high-quality, convenient and safe type of transportation. The passenger will choose the mode of transport where the quality of service (guarantees of politeness, friendliness, comfort, speed, safety, etc.) is the highest. Transport companies selected according to such criteria will have higher incomes, profits, and will be the most competitive. The purpose of the work: development of measures to improve the efficiency of passenger transportation in urban electric transport. In the process of writing the article, the following tasks were performed: statistical data of passenger transportation by urban electric transport in Ukraine and in the city of Dnipro were analyzed; a model of optimal distribution of rolling stock on the routes of urban electric transport has been developed; The optimization problem has been solved and the results of the solution have been analyzed. The developed optimization model makes it possible to optimize the number of rolling stock that carries the available passenger traffic on routes, reduce operating costs and increase the level of comfort for passengers. The main characteristics of some trolleybus routes in the city of Dnipro were also calculated; The main operational characteristics of these routes are calculated, according to which the intervals of movement of trolleybuses, the time of rotation on the route were determined. As a result of the calculation of the optimization model, it was obtained that it is necessary to have 52 units of rolling stock, instead of 56 (by 8%), to increase the average comfort coefficient by 15.7%, to reduce the cost of an hour of work by 3273.7 UAH (8%). It should be noted that the decrease in rolling stock affects the interval of movement of trolleybuses, but this decrease occurs on routes where there is a large number of rolling stock. The interval will increase by an average of 1.5 minutes, which is acceptable for passengers to wait. Measures can also be taken to increase the speed of trolleybuses, for example, the allocation of a lane for public transport on Ave. Slobozhansky.

H. I. Nesterenko, M. I. Muzykin, O. H. Strelko, S. I. Bibik, A. O. Aleksieieva — Mon, 18 Dec 2023 00:00:00 +0200

This article is devoted to the analysis of transport networks of such European countries as Ukraine, Hungary, and Romania. The article provides an analysis of the peculiarities in the movement organization in these countries. The transport systems of these countries were researched since during the war the issue of the interaction of the automobile transport networks exactly in these countries became particularly relevant. After all, there are incredibly long queues at the checkpoints in Poland because of strikes by Polish customs officers. And, therefore, the routes through Romania and Hungary are the most realistic both during the export of goods from Ukraine and to import humanitarian goods. The joint use of Europe's integrated systems is a necessary component in the organization of the effective operation of road transport, as it ensures increased efficiency in the use of the motor vehicle fleet and personnel; reduction of costs for maintenance, fuel, lubricants due to optimization of routes and reduction of non-productive vehicle mileage; reduction of the need to expand the motor vehicle fleet; clearer prospective planning of work based on objective information about the real mileage of each vehicle unit and reduction of losses related to repairs and expansion of the range of services and prompt response to requests. It is advisable to conduct further research in the direction of adapting the use of augmented reality technology in the driver's navigation systems.

PASSENGERS SERVICE QUALITY BY AIRLINES IN AIRPORT COMPLEXES

N. O. Semchenko, Ye. O. Ukrainskyi — Mon, 18 Dec 2023 00:00:00 +0200

In order to increase the competitiveness of airport complexes on the world market of air transport services, enterprises have to pay special attention to quality issues. The primary indicators of the quality of services in aviation are aviation safety, regularity of flights and service. But the range of needs of aviation service users is constantly expanding and the requirements for ensuring their quality are growing. When evaluating the level of aviation service, the passenger perceives the service as a whole. For him, it is not important who provides these services – the airline or the airport. The passenger equates the provision of services exclusively with the results of the airline's activities. Therefore, airlines are engaged in improving the service, both on the ground and during the flight. The article is devoted to the determination of factors affecting the quality of passenger service in airport complexes. The quality of services is a component of ensuring the competitiveness of airlines. The article presents criteria for evaluating the quality of passenger service in airport complexes, including services on board the plane. A methodology for assessing the quality of airport complex services has been developed. The methodology involves surveying passengers with the aim of obtaining personal and general information about the quality of services provided, identifying shortcomings in passenger service in airport complexes and further improving the quality of their work. Also, the survey will allow to determine the main directions of the management's work to improve the quality of the airport complex. This, in turn, will lead to an increase in the economic performance of the airport complex. The practical significance of the research results lies in the possibility of using them as a management technique for the service quality system of the airport complex. Separate provisions can be used by airlines for the comprehensive development of the existing competitive potential and the achievement of their successful functioning on the market.

MULTI-BAND GRAPHIC EQUALISER BASED ON GYRATORS

А. О. Semenov, О. V. Stalchenko, А. А. Khloba, B. O. Pinaiev, A. V. Krystoforov — Mon, 18 Dec 2023 00:00:00 +0200

Studies of the properties of human hearing have shown that the perception of loudness depends on both the frequency and intensity of sound. A person is able to compare the loudness of sounds of different frequencies. This allows us to construct so-called equal loudness curves (isophones). From them, it can be concluded that when the volume level is reduced, a person perceives sound components in the low and high frequencies of the sound range poorly, and at frequencies from 2 to 6 kHz, the ear is most sensitive to sounds. Therefore, it is with the help of an equalizer that sound correction is performed in accordance with equal volume curves. The purpose of this paper is to find a way to build an active eight-band equalizer to adjust the frequency response shape. This task can be solved in several ways. In the preliminary study, the three most common control principles were identified and analyzed, namely graphic equalizers based on an operational amplifier, bandpass filter signal addition, and an active filter with a feedback loop. Comparison of the latter with an equalizer based on an operational amplifier gave the following result: both have a uniform frequency response, but compared to the low-Q filters, the gyrator-based circuits have a higher quality, which gives an advantage to the operational amplifier-based equalizer because to obtain better quality factor and better stability of the EQ parameters based on the inclusion of a bandpass filter in the feedback loop, more complex filters that can accommodate two OPs and more elements must be used, which is not economical and will lead to an increase in size. It was also noticed that when adjusting the depth of control, the largest increase will be at the extreme positions of the slider, while at the middle positions, the slider has little effect on the depth, which is a big disadvantage. The same effect was observed for the developed scheme but with a smaller impact. But these effects are insignificant and can be ignored. The worst results are obtained with the equalizer with the addition of bandpass filter signals since it has frequency response fluctuations along the entire frequency axis at the middle positions of the sliders, and it also has the disadvantage of adjusting the frequency response in the attenuation direction, which is insignificant compared to the gain side. In order to increase the depth of control in the attenuation direction, it is necessary to increase the quality factor of the filters, and this, in turn, will lead to an increase in frequency response fluctuations, so it is undesirable to use this scheme.

VIRTUAL LABORATORY AS AN EFFECTIVE SOLUTION DURING DISTANCE EDUCATION

M. Yu. Tiahunova, V. R. Lavryk — Mon, 18 Dec 2023 00:00:00 +0200

In a world where the pace of change and technology is rapidly accelerating, education is more crucial and relevant than ever before. Recent developments in the education sector have fundamentally changed the paradigm of learning, particularly due to two key events: the COVID-19 pandemic and the onset of the war in Ukraine in 2022. These challenges demand new and innovative solutions in the educational process. Meanwhile, the situation in educational institutions has significantly complicated due to the onset of the war in Ukraine in 2022. Risks for students and educators, associated with being on university campuses during conflict, have increased, raising important questions about how to conduct and teach classes during wartime. A common factor that played a vital role in addressing these issues was the presence of a gadget that is almost ubiquitous: the mobile phone. This device became a bridge between students and educators, enabling the delivery of lectures and practical sessions online even when physical access to the university was restricted. Virtual laboratories emerge as a response to modern challenges in education, providing students with the opportunity to receive quality education amidst constraints and crisis. Virtual laboratories allow students to develop skills and enhance their knowledge without leaving home or a safe location. These innovative solutions support the learning process and contribute to the improvement of educational quality. Thus, virtual computer laboratories are an essential element of the educational space that can guarantee learning and development for students even in the most challenging situations. The paper analyzes the subject area, identifies tasks to be addressed when creating a virtual laboratory, and examines the software for remote laboratory access. Examples of tasks relevant to computer engineering are described, along with general features of tasks suitable for virtual laboratories. The paper develops a structural scheme of a virtual laboratory based on the proposed task directions. The choice of hardware and software components for the virtual laboratory within the university and for remote users is proposed and justified. The paper also outlines and describes the algorithm of the system's functioning as a whole.

The article examines the current state and dynamics of the development of the hotel services market in Ukraine by determining the peculiarities of the change in statistical parameters characterizing the activity of business entities in the field of hospitality. The main goal of this article is to analyze the market of hotel services in Ukraine, to assess its current state and development trends based on the dynamics of performance indicators of collective accommodation facilities. In the work, by conducting a quantitative analysis of the data of the State Statistics Service of Ukraine, the current state of the market of hotel services in the country, its structure, features and development trends is characterized, taking into account the classification of types of economic activity according to KVED-2010. By interpreting the indicators of the number of hotels and similar accommodation facilities, persons staying in collective accommodation facilities, employed workers in the hotel sector, and the volume of implementation and production of hotel services, trends in their development in Ukraine were established. So, based on the assessment of the dynamics of these statistical indicators, negative trends in their development in Ukraine in the last three years have been established, which is explained by the negative impact of the COVID-19 pandemic, political and economic crisis phenomena in the country and the world. In the course of the research, it was determined that Odesa, Zakarpattia, Lviv, and Kyiv regions have the largest number of hotels and similar accommodation facilities, and, accordingly, greater profit from this activity. The growth of the role of individual entrepreneurs in the hotel industry and the directions of their cooperation with hotel chains, which involve the pooling of resources, knowledge and innovative activity of FOPs to create new consumer offers, have also been established. The growth of the share of FOPs in the structure of business entities in the hotel services market is explained by the simple procedure of their registration, lower costs of business management, greater productivity and efficiency of service implementation, flexibility in decision-making, provision of innovative services and introduction of new concepts, as well as the need to ensure self employment.

V. A. Yazina, O. V. Vyshnikina, O. V. Sabirov, S. O. Haponenko, N. O. Hurbych — Mon, 18 Dec 2023 00:00:00 +0200

The article is devoted to the study of food safety management at restaurant enterprises. Improving food safety management at restaurant enterprises involves the use of the latest technologies and standards, as well as taking into account legislative requirements in the field of food safety. The enterprise must have appropriate procedures and instructions for the organization of food quality and safety control, as well as ensuring hygiene in the kitchen and in the restaurant. It is also important to ensure that food safety personnel are properly trained and educated so that they can apply procedures and standards correctly. In addition, the company must use high-quality and verified food suppliers. The concept of food safety was considered and its structural elements were determined. The basic principles of food safety management at restaurant enterprises were established. Relevant modern international organizations, their activities and the importance of influence on food safety are analyzed. The main documents at the state level responsible for regulating food safety have been identified. The main incidents of food safety violations and ways to eliminate them are considered. The relevance of the problem of improving food safety management at restaurant enterprises has been proven. The key problems in the field of food safety at restaurant enterprises were studied and the prospects for the development of food safety at restaurant enterprises were determined. Recommendations for improving food safety management at restaurant enterprises have been developed. Improving food safety management at restaurant enterprises is an important element of ensuring the restaurant's competitiveness and reputation. Customers will be more inclined to choose restaurants that maintain high standards of food quality and safety. The research is relevant in modern conditions, as food safety is becoming an increasingly important problem in the restaurant industry. The global COVID-19 pandemic has exacerbated this problem as people have become more aware of hygiene standards in public places, including restaurants.
