Progressive digitization and dynamic development of ICT technologies generate new opportunities for industry, logistics, society and education. Education in Science, Technology, Engineering, Mathematics (STEM), also called ‘the education of the future’, has become of great importance, because we are experiencing a shortage of STEM workers in various sectors. The effectiveness of STEM e-learning as a teaching method should be a key principle in management of this process. The main goal of the paper is to present a process approach to e-learning of automated transportation used in production logistics. The framework allows one to identify and optimise processes, and it may contribute to efficient management of distance learning. Moreover, it could improve the process of software development and software design skills. Desk research analyses were carried out to describe the state of art in the field of STEM education and potential of process management for remote teaching. In the empirical part of the paper, the modelling was based on the main assumptions of process management and BPMN (Business Process Modelling Notation), and dedicated process mapping software was used. The article examines the potential of the process approach and confirms that it can contribute to increasing the effectiveness of distance learning in the field of STEM. As a result of modelling, the optimization concepts regarding designing the e-learning course and the possibility of expanding the existing model towards acquiring more skills, for instance in programming PLC controllers were indicated. The developed model is a starting point for improving teaching of STEM for production, logistics, engineering and other domains.

Subject of the study: the process of acoustic information protection in computer systems of critical applications to ensure the required level of system security. The aim of the article is to analyze the methods of acoustic information protection in computer systems of critical application by means of masking to ensure the impossibility of unauthorized access to the system. The article solves the following tasks: to analyze the software and hardware masking of speech; to study the masking of speech messages in order to introduce unrecognizability; to study the features of speech message compression; to investigate methods of covert transmission of acoustic information. The results of the work, which were obtained using mathematical methods of information transformation in computer systems, are potentially possible methods of masking speech messages to ensure the impossibility of unauthorized access to the system. The analysis of the functioning of the presented methods has led to the following conclusions. One of the perspective directions of acoustic information protection in communication channels and dedicated premises can be considered the creation and development of computerized speech masking systems along with or in conjunction with traditional technologies of semantic protection of acoustic information, namely, speech signal classification based on cryptographic algorithms. The main requirements for today's systems that provide protection of acoustic information in critical computer systems are speed and efficiency of various speech signal processing procedures using standard inexpensive technical means of computer telephony, namely: a personal computer, sound card, telephone line interface device and/or modem. These requirements can be met by applying digital methods of dynamic spectral analysis, i.e. synthesis of speech and audio signals. The choice of specific methods and means of speech masking as one of the types of semantic protection of acoustic information will depend on the practical requirements for the speech protection system and the technical characteristics of the acoustic information transmission channel. Further research is desirable to analyze the possible use of methods for synthesizing large ensembles of quasi-orthogonal discrete signals with improved ensemble, structural and correlation properties to ensure higher security indicators of acoustic channels in computer systems of critical applications.

Providing effective cybersecurity for corporate computers is an extremely important and complex task that requires careful choice of software and hardware. This article discusses the key components of cybersecurity software and hardware - antivirus programs and hardware firewalls. Considering the rapid growth of cyber threats, it becomes clear that comparing individual characteristics no longer allows users to make the right choice. For example, when it comes to antivirus software, it is no longer possible to simply focus on the size of the virus database, as the number of viruses reaches a billion, and even the most powerful computer is not enough to scan every executable file for a match. Similar challenges arise with the choice of hardware. Modern hardware firewalls are no longer limited to simply analyzing traffic by packet headers and dropping unwanted addresses or ports. They must filter complex traffic, including encrypted traffic, and provide reliable protection while delivering high performance to meet user needs. It is also worth noting that the choice of hardware should take into account the network architecture, scalability, and planning for future needs. Since it is becoming increasingly difficult to make the appropriate choice of cybersecurity software and hardware, the authors of the article propose to automate the choice using advances in modern decision theory. The authors present algorithms for choosing tools based on personal needs and the opinions of an expert group. The authors demonstrate the effectiveness of these algorithms for solving real-world selection problems in the industry with the help of software specially developed by the authors for automated selection of software and hardware components of the corporate computer cybersecurity system.

experiments based on multilevel computer simulations, which are becoming widespread today in scientific research practices, are forcing philosophers of science to shift the focus of attention from traditional concepts of scientific experiments to a fundamentally new methodology for designing, setting up and conducting an experiment. The computational power of modern high-performance clusters, which allow the creation of unique computer simulations of target systems and environments in which an experiment is affected, inspire various specialists to investigate the status of such experiments, their epistemological value and ontological consistency before field, laboratory and thought experiments. Some philosophers, imbued with the technological capabilities of computing systems, dare to pose fundamental questions about the nature of knowledge, thinking and ontology. The author of this article, hoping and striving to contribute to this type of research, will attempt to provide a relevant description of the conceptual methodology for developing computer simulations for conducting scientific experiments based on the fundamental work of the founder of German classical philosophy, I. Kant. In the first part, the methodological basis of the development of simulations concerning transcendental aesthetics is deduced, in the second with transcendental analytics and in the third, the limits of the ontology of computer simulations of scientific experiments are revealed following the Transcendental philosophy.

Management and differentiation of access to computer systems and their resources is one of the important aspects of information security, which can be implemented by identifying users. Recently, identification systems that use biometric characteristics of a person to solve the problem of access to information systems are becoming more and more widespread. The paper proposes a new method for biometric identification of users of computer systems based on the definition of the Volterra integral model of the human oculo-motor system (OMS) based on the data of experimental "input-output" studies using innovative eye tracking technology. The aim of the work is to increase the efficiency (reliability) of information protection in computer systems through the development of hardware and software tools for identifying human OMS based on a nonlinear dynamic model and experimental eye tracking data using test visual stimuli. The object of the research is the process of biometric identification of a computer system user based on eye tracking data in dynamics - responses to given test visual stimuli. The subject of the research is instrumental algorithmic and software tools for constructing the Volterra model - assessing the multidimensional transition functions of the OMS based on eye tracking data. OMS identification software was developed in the Python IDLE programming environment. Test visual stimuli are used in the form of bright dots, which are sequentially displayed on the display screen at different distances from the starting position, which formally corresponds to different amplitudes of test step signals. Experimental studies of OMS were carried out in two individuals. Based on the data obtained using the TOBII PRO TX300 eye tracker, the transition functions of the first, second and third orders of the OMS are determined. A significant difference in the diagonal sections of the transition functions of the second and third orders was revealed in two individuals. Consequently, they can be used to form a space of informative features and build statistical classifiers of individuals using machine learning tools that implement the proposed method for protecting information in computer systems based on biometric identification of users based on eye tracking data. The proposed method of biometric identification and the developed means of introducing information protection mechanisms in computer information systems have the ability to flexibly control security, depending on the requirements put forward, the permissible risks and optimal resource costs.

In article the method of optimization of processing of a large volume of the data intended for diagnostics of a condition of the equipment of difficult technical systems is offered. Such diagnostics allows to increase the efficiency of the analysis of faults in technical systems with a view to their early elimination. This is achieved by predicting the failure of critically vulnerable systems capable of decommissioning the vehicle, or lead to consequences that threaten people's lives. The method is implemented in an information system based on a set of algorithmic consistency aimed at identifying information in highload networks and its processing at the time of transmission from complex technical systems to the Central data warehouse. The functioning of the information system is based on the use of hybrid algorithms for searching and sorting data, the concept of Data Mining, as well as algorithms for working with large amounts of data. The methods of data selection and distribution are carried out at the level of sensor readings control of the technical system and distributed until recording in the data warehouse. This allows to identify the information necessary for the prediction of failure of critically vulnerable technical systems. In order to increase the speed of data processing, the C\C++ development language is used, which allows the information system to interact with the reading control sensors. As a data warehouse uses the relational and not relational database, allowing to save large amounts of data and provide constant access to data. The developed information system can be used in vehicles with the system used to monitor the readings in real time. [ABSTRACT FROM AUTHOR]

Software verification tools have achieved enormous progress and are becoming practically usable to a broad set of users. Over the last years, regression verification, a special sort of software verification, is also practically considered. In regression verification, similarly as in regression testing, functional correctness of a program is checked by analyzing its equivalence with the program which is assumed to be correct. Of course, regression verification, when applicable, provides much more reliable and deeper conclusions than regression testing. In this paper we briefly describe basic concepts of software verification and show that the verification system LAV can be successfully used for regression verification. Possible applications are in software development (as an alternative to regression testing), but also in education, for automatic evaluation of students' programs. [ABSTRACT FROM AUTHOR]

A method has been proposed to recognize and predict the range values of acute toxicity (LD50) and for this a system has been developed. The essence of the method is to gradually decrease the predictable toxicity ranges for the test substances in a stepwise manner while advancing within the formed predictive complexes. The transmission of information on the structure of compounds along this complex is determined by the preset logistic scheme along which narrower LD50 ranges are designated. The intervals are automatically set, by optimizing the recognition of the properties of compounds at the stage of formation of models (that recognize the set of signs). The predicting system includes two predicting complexes and contains a total of 30 mathematical models: for heterocyclic and carbocyclic compounds. Logistic schemes for passage of predictable compounds have been developed for each complex in accordance with the hierarchic organization of the elements that are constituents of the complex. The prediction significance is 70-90%.
