Ensuring the full and effective use of this information requires the use of the latest improved algorithms for compaction and optimization of its storage. The further growth of the technical level of hardware and software is closely related to the problems of lack of memory for storage, which also actualizes the task of effective data compression. Improved compression algorithms allow more efficient use of storage resources and reduce data transfer time over the network. Every year, programmers, scientists, and researchers look for ways to improve existing algorithms, as well as invent new ones, because every algorithm, even if it is simple, has its potential for improvement. A wide range of technologies related to the collection, processing, storage and transmission of information are largely oriented towards the development of systems in which graphical presentation of information has an advantage over other types of presentation. The development of modern computer systems and networks has influenced the wide distribution of tools operating with digital images. It is clear that storing and transferring a large number of images in their original, unprocessed form is a rather resource-intensive task. In turn, modern multimedia systems have gained considerable popularity thanks, first of all, to effective means of compressing graphic information. Image compression is a key factor in improving the efficiency of data transfer and the use of computing resources. The work is devoted to the study of the modification of the data compression algorithm The Quite OK Image Format, or QOI, which is optimized for speed for the compression of graphic information. Testing of those implementations of the algorithm, which were proposed by its author, shows such encouraging results that it can make it competitive with the already known PNG algorithm, providing a higher compression speed and targeting work with archives. The article compares the results of the two proposed modifications of the algorithm with the original implementation and shows their advantages. The effectiveness of the modifications and the features of their application for various cases were evaluated. A comparison of file compression coefficients, which were compressed by the original QOI algorithm, with such coefficients, which were obtained as a result of the application of modifications of its initial version, was also carried out.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

A comprehensive analysis of existing studies within virtual biocenoses was undertaken to glean valuable insights into the complexities of modeling dynamic ecosystems where artificial agents engaged in intricate interactions. The pivotal role of neural networks in shaping the adaptive behaviors of artificial creatures within these environments was underscored. A meticulous investigation into neural networks' evolution methodologies revealed the evolution of their architecture complexity over time, culminating in the facilitation of flexible and intelligent behaviors. However, a lack of study existed in the domain of nurturing evolutionary-based communication and cooperation capabilities within virtual biocenoses. In response to this gap, a model was introduced and substantiated through simulation experiments. The simulation results vividly illustrated the model's remarkable capacity to engender adaptive creatures endowed with the capability to efficiently respond to dynamic environmental changes. These adaptive entities displayed efficient optimization of energy consumption and resource acquisition. Moreover, they manifested both intellectual and physical transformations attributed to the evolution and encoding principles inspired by the NeuroEvolution of Augmented Topologies. Significantly, it became apparent that the evolutionary processes intrinsic to the model were inextricably linked to the environment itself, thus harmonizing seamlessly with the overarching goal of this research. Future research directions in this field were outlined. These pathways provided a foundation for further exploration into the evolution of artificial creatures in virtual biocenoses and the emergence of advanced communication and cooperation capabilities. These advancements hold the potential to move artificial life and artificial intelligence to new levels of understanding and capability.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

Economic modeling is one of the important modern tools for assessing the impact of technologies on the economic sector in order to obtain an optimal solution. Economic evaluations can be based on several different modeling approaches, each with its own strengths and weaknesses. The relevance of the use of economic and mathematical models for the purpose of studying demography is connected with the need to study population and migration processes, as well as for further planning and implementation of the country's economic and social development. In every sphere of the economy, there are phenomena that are interesting and important to study in their development, as they evolve over time. Prices, economic conditions, industrial processes, and demographic data tend to change over time. The set of measurements of this kind of indicators depending on time is a time series. The goals of studying time series can be different. It is possible, for example, to try to predict the future on the basis of knowledge of the past, to control the process that generates the series, to try to find out the mechanism underlying the process, to clear the series of components that obscure its dynamics, or simply to briefly describe the characteristic features of the series. When studying the relationships between indicators or when analyzing their development over time, not only the current value of the variables, but also some previous values in time, as well as time itself, are used as explanatory variables. Models of this type are called dynamic. In economic analysis, dynamic models are used quite widely. This is quite natural, because in many cases the influence of some economic factors on others is not carried out immediately, but with some delay − a lag. The object of research is the mathematical model of the interdependence of the vector time series \"Births in Ukraine for January 2005 − July 2012.\" The data are chosen quite relevantly, because without a preliminary demographic forecast it is impossible to imagine the prospects of industry and consumption of goods and services, housing construction, development of social infrastructure, health care and education, pension system and solutions to geopolitical problems.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

The possibility of building nonstationary random process correlation theory was considered in the monographs by M. S. Livshits, A. A. Yantsevich, V. A. Zolotarev and others. Some classes of nonstationary curves were investigated by V. E. Katsnelson. In this paper nonstationary random processes are represented as curves in Hilbert space which \"slightly deviate\" from random processes with the correlation function of special kind. The infinitesimal correlation function has been introduced; in essence, this function characterizes the deviation from the correlation process with the given correlation function. The paper discusses the cases of nonstationary random processes, the operator of which has one‑dimensional imaginary component. Cases of a dissipative operator with descrete spectrum are also considered in this work. It is shown that the nonstationarity of the random process is closely related to the deviation of the operator from its conjugated operator. Using the triangle and universal models of non‑self‑ajoint operators it is possible to obtain the representation for the correlation function in the case of nonstationary process which replaces the Bochner – Khinchin representation for stationary random processes. The expresson for the infinitesimal correlation function was obtained for different cases of operator spectrum: for the descrete spectrum placed in the upper half‑plane and for the contrast‑free spectrum at zero. In the case of dissipative operator with descrete spectrum the infinitesimal function can be found in terms of special lambda function. For Lebesque spaces of compex‑valued squared integratable functions the expresson of infinitesimal function was found in terms of special zero order modified Bessel function. It was shown that a similar approach can be applied for the evolutionarily represented sequences in Hilbert spaces.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

Effective management organization and automation of activities of employees of recruiting agencies is not an easy task. The system should automate the routine actions of workers of recruiting agencies and be convenient for their clients. This paper proposes an approach to automating the selection of necessary medical staff. Not all information systems used by recruiting agencies can compare candidates and generate results that include several of the best candidates. Based on the analysis of the subject area, groups of parameters that significantly affect the choice of medical personnel were determined. The proposed approach is to analyze the request from the client, and then in the system find requests of other clients similar to it in terms of parameters, for which a candidate has already been found. The next step is to take the profiles of healthcare professionals that have been suggested for these requests (they act as benchmarks) to further compare them with existing candidates. Each employee profile parameter has its own similarity function. Available candidates will receive scores and will be ranked. We also additionally adjust the assessment by comparing candidates with the current request. Software was developed to automate the selection of medical personnel. For its implementation, a three-level client-server architecture is proposed. MVC (Model View Controller) architecture was chosen for the server part. The Single Page Application architectural template is used for the client part. The server part is divided into three layers, which further demarcate and structure the responsibilities of the system components. .NET technologies are used to implement business logic. SQL Server is used for the server and database provider. The use of the software implementation of the developed system demonstrated quite good results. The average time for selecting the 10 best candidates out of 500 is 0.4 seconds, and the processing of only 1 resume by a person takes several minutes.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

Modern development uses new microservice architectural to improve performance, portability, and other important characteristics. This necessitates the transformation of legacy systems from a monolithic architecture to a microservices one. Such a process is complex and costly, so improving the methods for converting old systems to a new platform is relevant. This research aims to develop a method of applying microfrontends approach for monolithic single page applications (SPA). The article proposes a method of transforming the software system architecture from monolithic to microservice architecture (MSA). Since the client part of the system is considered, the term microfrontend is proposed, as an analog of microservers in the server part of the software systems. A brief review of existing architecture reengineering research is made and the advantages of a microservice approach are identified. The proposed three-stage method differs from the methods by the selection of an additional stage of conversion, which allows to gently change the connections between parts of the monolithic application, which were implemented in the initial monolithic architecture. The first stage is reverse engineering, it is proposed to shift the focus from the search for outdated code to the functional analysis of the program as such. The second stage, a transition to a modular architecture with the allocation of functionality into separate modules is proposed. At the end of the third stage, we have several separate programs (microinterfaces) that are connected to the main program. An experiment with a typical external SPA demonstrates the operation of the proposed algorithm. The system obtained as a result of the transformation is compared with the original one according to the following measurable parameters: production builds building time, size of the main bundle, and first page average load time. All comparisons showed the advantages of the system obtained as a result of the conversion. As a result, the architecture transformation algorithm allows you to obtain a guaranteed better result, taking into account the limitations of the interface SPA, which were not considered by the authors of previous articles.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

Remote attacks on computer systems are becoming more common and more dangerous nowadays. This is due to several factors, some of which are as follows: first of all, the usage of computer networks and network infrastructure overall is on the rise, with tools such as messengers, email, and so on. Second, alongside increased usage, the amount of sensitive information being transmitted over networks has also grown. Third, the usage of computer networks for complex systems, such as grid and cloud computing, as well as IoT and “smart” locations (e.g., “smart city”) has also seen an increase. Detecting malicious network traffic is the first step in defending against a remote attack. Historically, this was handled by a variety of algorithms, including machine learning algorithms such as clustering. \u0000However, these algorithms require a large amount of sample data to be effective against a given attack. This means that defending against zero‑day attacks or attacks with high variance in input data proves difficult for such algorithms. In this paper, we propose a semi‑supervised generative adversarial network (GAN) to train a discriminator model to categorize malicious traffic as well as identify malicious and non‑malicious traffic. The proposed solution consists of a GAN generator that creates tabular data representing network traffic from a remote attack and a classifier deep neural network for said traffic. The main goal is to achieve accurate categorization of malicious traffic with a few labeled examples. This can also, in theory, improve classification accuracy compared to fully supervised models. It may also improve the model’s performance against completely new types of attacks. The resulting model shows a prediction accuracy of 91 %, which is lower than a conventional deep learning model; however, this accuracy is achieved with a small sample of data (under 1000 labeled examples). As such, the results of this research may be used to improve computer system security, for example, by using dynamic firewall rule adjustments based on the results of incoming traffic classification. The proposed model was implemented and tested in the Python programming language and the TensorFlow framework. The dataset used for testing is the NSL‑KDD dataset.","PeriodicalId":391969,"journal":{"name":"Bulletin of National Technical University \"KhPI\".

Business process modeling stands as the central technology within the entire BPM methodology. In line with the BPM lifecycle, these models visually represent current organizational activities that necessitate improvement using various diagramming notations. These graphical business process models can subsequently be employed to analyze ongoing activities in the enterprise, identifying potential drawbacks or “weak spots” that hinder the company’s performance. Through business process models, organizations can modify the “virtual twins” of their organizational workflows, conduct simulations, and make informed decisions for business process improvement. Thus, business process models constitute the most valuable assets of the organization, conveying knowledge about ongoing activities and potentially encapsulating the best organizational or industry practices. The implementation of a centralized database for business process models can significantly benefit the entire organization, enhancing the efficiency of knowledge sharing and accumulation. However, centralized business process model repositories prove less efficient for inter-organizational knowledge exchange. Additionally, most business process models require significant person-hours for development and cannot be shared freely with competitors. The exchange of business process models should adhere to established mechanisms for managing valuable digital assets. Presently, Distributed Ledger Technologies (DLT), especially Blockchain, have gained enormous popularity. Therefore, we can employ the principles of Blockchain technology and the cryptocurrency industry to create software for the Decentralized Exchange (DEX) of business process models.
