Detector Artificial Neural Network. Neurobiological rationale
(ХНУРЕ, 2019) Parzhin, Yu.; Rohovyi, А.; Nevliudova, V.
On the basis of the formulated hypotheses the information model of a neuron-detector is suggested, the detector being one of the basic elements of a detector artificial neural network (DANN). The paper subjects the connectionist paradigm of ANN building to criticism and suggests a new presentation paradigm for ANN building and neuroelements (NE) learning. The adequacy of the suggested model is proved by the fact that is does not contradict the modern propositions of neuropsychology and neurophysiology.

(ХНУРЕ, 2017) Sotnik, S. V.; Nevliudova, V.; Malaya, I.
Today the information environment is highly developed, it enables collecting, processing, storing, distributing, searching and transferring of information. The need for automation of information activities and information resources management at all levels stipulates the demand for the development of information search systems. The subject matter of this research is the information search system for selecting the moulds forming elements. The aim of this work is to reduce the time for searching and determining the main parameters of the matrices, punches and characters by means of creating the information search system for selecting the moulds forming elements. To achieve this goal the following tasks should be solved: to review the main moulds forming elements and their technical parameters; to develop a search algorithm; to develop the database structure for selecting the moulds forming elements; to design the interface of the information search system. While solving the set tasks, the methodology of the systems analysis and modelling was used. The review the main objectives and characteristics of information search systems resulted in the development of the database logical structure which consists of 6 tables. The interface of the information search system was developed. It provides the “easy” and self-explanatory selection of moulds forming elements. Thus, the developed system includes information about the unique number of the forming elements; their type, name and properties; material and features of the quality of a workpiece surface; a workpiece kind and form to determine the nominal dimensions of forming elements. The use of the system enables reducing the time of searching and identifying forming the key technical parameters of forming elements as well as storing and manipulating the data about these elements.

(ХНУРЕ, 2019) Nevliudov, I.; Demska, N.; Starodubcev, N. ; Nevliudova, V.
Modern technologies move away from the traditional design of hard electronics into the form factors of flexible switching structures, which are often operated in a dynamic mode and can be subjected to such actions as alternating loads, bending and twisting, stretching, vibration, the presence of a chemically aggressive environment, etc. Despite a large number of existing studies using an arsenal of achievements in the field of materials science, means of classical and quantum physics, the theory of chemical reactions, statistical physics, fracture mechanics, up to date, some essential phenomena occurring at the atomic-molecular level during the implementation of the manufacturing process and design of flexible structures have not been fully disclosed. In this paper, we consider the processes of the appearance in the materials and structures of connectors of products of physicochemical reactions associated with the presence of two sources of medium formation, which are interpreted as the formation in a certain place, over a certain period of time, of a substance with new properties, the appearance of which can cause degradation processes. As a result, the obtained dependences, together with the statistical processing of the obtained information, can provide a sufficient description of the process for its optimal control, even under conditions of incomplete certainty about the subtle mechanisms of atomic-molecular interaction between the materials involved in the process.

(ХНУРЕ, 2021) Osadchy, S.; Demska, N.; Oleksandrov, Yu.; Nevliudova, V.
The development of cyber-physical production systems is a complex scientific and technical task, therefore the developer needs to determine the requirements, tasks for the system being developed and choose an architectural model for its implementation. In turn, the choice of an architectural model assumes a balance for the set of requirements of persons interested in its development. In a typical case, the development of a specific cyber-physical industrial systems needs to be adapted to the means of implementation, to the realities of its future use, maintenance and evolution. Subject matter of this study are architectural models for building complex cyber-physical production systems. Goal of this article is a study of architectural models DIKW and 5C, according to the results of the decomposition of which, in the future, it will be possible to carry out a mathematical description of elementary problems of each level and their physical or simulation modeling. To achieve this goal, it is necessary to solve the following tasks: analyze the DIKW model; analyze the architectural model 5C; compare the DIKW model and the 5C architectural model, using its structural decomposition into levels, information and command channels with feedback within each structure. The research carried out is based on the methods of decomposition and formalized representation of systems. Conclusions: Based on the results of the decomposition at each structural level of the DIKW and 5C models, a decomposition structure was developed, which shows the main differences and general similarities of the models. It was revealed that the 5C model, as a common software shell that combines integrated sensors and actuators, is more suitable for solving problems of developing a cyber-physical production system, and the DIKW interpretation model is more suitable for solving problems of modifying existing systems at enterprises, and the choice of the model itself the development of a cyber-physical production system depends on the requirements of the customer, existing equipment, the level of its automation and the level of project financing.

(ХНУРЕ, 2023) Andrusevich, A.; Omarov, S.; Starodubcev, N.; Nevliudova, V.
Industry 4.0 envisages a comprehensive transformation of all industries by combining digital technologies and the Internet with traditional industries. It is important to emphasize that Industry 4.0 relies heavily on robotics. Robotization opens up new opportunities for an industrial enterprise, completely transforming the technologies and organization of its production process and business model. Many of today’s threats to the economic security of an industrial enterprise can be mitigated due to digitalization and flexible robotization of production and promotion of goods. But at the same time, processes related to the robotization of the economy create new threats to economic and social security. The consequences of their influence and the mechanisms of their leveling are the subject of research. The goal of the work is to study the impact of robotics on the economic security of an industrial enterprise. The following tasks are solved in the article: an overview of the areas of application and trends in the development of industrial robots; overview of the robotics market; analysis of risks and threats to the economic security of industrial enterprises arising as a result of robotization. The methods of system analysis, graphic generalization and classification are used. The results of the work include an analysis of the current state of robotics and the introduction of industrial robots in production, a brief analysis of the robotics market and a study of external challenges, uncertainties and risks arising from robotics: political-economic, technological, financial and environmental. Conclusions. The development of robotics is a priority direction for innovative industrialization not only in the long term, but also in the short trm. Robotics can also become a locomotive for general economic growth, given that the most advanced developed countries are currently creating their own robotic enterprises and transferring production from developing countries to them. However, in the context of robotization, it should be taken into account that these processes, along with potential benefits for the industrial enterprise, can also create new threats to economic and social security.

(НТУ «ХПИ», 2019) Artiukh, R.; Nevliudova, V.
The paper deals with the issues of automating the process of the business personnel selection since the general management of the organization depends on the right approach to personnel tasks. Personnel selection for an enterprise is a very important and complex process and it should follow the appropriate algorithm. Among current technologies of personnel selection, three basic ones should be distinguished; they are headhunting, recruiting and screening. To find specialists, recruitment officers often use various channels including professional networks, recommendations, and corporate databases. The following stages of the process of personnel selection are proposed: receiving job requisitions; analyzing the labour market; choosing and implementing the techniques of personnel selection methods.
