Metrological support of pulse oximeters
(Національний технічний університет "Харківський політехнічний інститут", 2022) Tverytnykova, Elena; Drozdova, Tatyana; Demidova, Yu. Ye.; Kuzmenko, Nataliia
The experience of the International Medical Device Regulators Forum in the use of products for oxygen therapy based on the study of guidelines, international and European regulations on medical devices is considered. Emphasis is placed on issues related to the metrological support of pulse oximeters. The global situation with the pandemic increases the relevance of selected topics. Continuous monitoring of blood oxygen saturation is one of the most important elements in the diagnosis and treatment of COVID-19. Despite the fact that the use of pulse oximeters does not require special medical knowledge, calibration and special maintenance, it is still necessary to control their reliability and accuracy of measurement. The study of pulse oximeter MD300M in accordance with the requirements of DSTU 8893:2019 "Metrology. Pulse oximeters. Calibration Method" 2020. Analysis of MD300M pulse oximeter calibration results revealed that this pulse oximeter was calibrated by the saturation and pulse measurement channel, as the maximum deviation of the measured saturation value from the pulse oximeter calibration measure does not exceed the pulse oximeter measurement documentation specified in the operating documentation. The discreteness of the MD300M pulse oximeter and the discreteness of the reference device MPPO-2, which are specified in the passports for the respective devices, have the greatest influence on the measurement uncertainty.
Punctured NCC codes for information protection in information and measurement systems
(Національний технічний університет "Харківський політехнічний інститут", 2022) Krylova, Victoria; Tverytnykova, Elena; Vasylchenkov, Oleg; Kolisnyk, Tatyana
During development and design of information-measuring systems, enabling to carry out collection, processing and transmission of information, one of the main problems is the choice of effective methods of information protection against defects in noisy communication channels. Effective use of frequency-time resources of information communication channels, as the most valuable part of the information transmission system, is the key to provide reliable delivery of transmitted messages. One of effective directions of reliability increase and information transfer reliability in information-measuring communication networks is implementation of methods and algorithms of noise-resistant coding, providing for detection and coping with errors, arising due to interferences in the communication channel. In this case, the choice in favor of one or another coding method depends on the information characteristics of the data channel. Parameters of the noise coder must be coordinated with the source of the message, the communication channel, as well as the requirements for the reliability of bringing information to the recipient. The problem of obtaining a wide range of codec parameters with simultaneous preservation of the unified macrostructure of the codec in communication systems causes the need for research on the development of adaptive algorithms for error information protection. In the article the research results of the characteristics of variable rate slot convolutional codes for adaptive coding/decoding in information-measuring systems of information transmission are proposed. Consequently, when creating communication networks, there is no need to use a large number of different codecs, even with completely different requirements to the code rate, channel rate and gain due to coding. In addition, there is a real opportunity to create terminal equipment, working on unified algorithms of protection against errors and access.
Professors of the Kharkiv Technological Institute: unknown pages of biography
(Державний університет інфраструктури та технологій, 2020) Tverytnykova, Elena; Gutnyk, Maryna; Salata, Halyna
The purpose of the study is to conduct a comprehensive historical and scientific analysis of the life and scientific and organizational activities of professors of the Kharkiv Technological Institute Oleksii Khinkulov and Pavlo Dedusenko, using the study of scientific literature and involved archival materials. On the basis of the involvement of unknown and little-known archival documents, a historical reconstruction of the creative activity of scientists was conducted; in particular, the little-known period of their life in 1940-1946 was studied in detail. A comprehensive analysis of the scientific activities of Oleksii Khinkulov was carried out, his contribution to the formation of the electrical industry was determined. His role in the development of scientific research in the field of radio engineering in Ukraine was emphasized. He headed one of the largest radio engineering club in Ukraine. The social activities of Oleksii Khinkulov were investigated, it was found that for a long time he worked as deputy chairman, and then as chairman of the All-Ukrainian Association of Engineers, which united the teams of research departments of technical institutions of Ukraine. The scientific and organizational activities of Professor Oleksii Khinkulov certainly contributed to the development of electrical engineering science and education both in Kharkov and in Ukraine. He was one of the organizers and promoters of the radio engineering direction in Ukraine, participated in the work of public organizations and electrical congresses. His colleague at KhTI, Professor of chemistry Pavlo Dedusenko, is undoubtedly an outstanding person. As an active member of various charities, he worked hard for the public. These are both scientific societies and various social projects. A supporter of Ukrainian nationalism, he strove for the Independence of Ukraine, the development of Ukrainian culture. Repressed in 1945, the scientist died in the concentration camp in 1946. In 1991, due to the lack of evidence confirming the guilt of Pavlo Dedusenko, the professor was rehabilitated.

(Національний технічний університет "Харківський політехнічний інститут", 2020) Tverytnykova, Elena; Drozdova, Tatyana; Demidova, Yu. Ye.
The results of activity and stages of implementation of various measures of environmental policy of the enterprise are considered on the example of Shebelinsky department of gas condensate and oil processing. The structural scheme of the ecological management system model as an important component of the integrated management system of the gas condensate and oil refining enterprise is proposed on the basis of scientific literature, regulatory and legal documents using structural-logical method, systematization and generalization, and methods of meaningful and comparative analysis. This work also describes the specifics of ecological standards implementation based on ISO 9000 and ISO 14000 series for integrated management system development. It has been proved in practice that development and implementation of the integrated management system in the natural gas liquids and oil processing enterprise provides certain advantages, specifically, improves the overall products competitiveness, helps to adapt faster to the market environment, shapes environmental policy and approaches for effective resource management. The integrated management system development process consists of 4 basic stages, namely, planning, implementation, verification, and adjustment. Complex process and system approach represents an integral part of the integrated management system development. While being gradually implemented, the application of the additive and simultaneous integration models made it possible to create a single management system based on the requirements of different standards and significantly reduce the documentation volume.
Application of user interface Fuzzy Logic Toolbox for quality control of products and services
(Національний технічний університет "Харківський політехнічний інститут", 2019) Hrihorenko, Igor; Drozdova, Tatyana; Hrihorenko, Svetlana; Tverytnykova, Elena
In this work, the solution for the quality control of products and services is illustrated for the first time on examples of wine production and the provision of educational services in the university by creating a heuristic analyzer based on the Fuzzy Logic Toolbox interface of the Matlab program. There were also considered the problems of constructing quality control models with fuzzy logic for solving problems arising in cases when it is not possible to use classical statistical methods. The factors influencing the quality of products, in particular wine, and services on the example of providing education are analyzed, the possibility of using the fuzzy logic apparatus for determining the weight contribution of factors that ensure maximum quality is proved. Computer simulation using the Mamdani algorithm is performed, which consists of fuzzification with the definition of ranges of change of input values for each example, assigning the distribution functions for each input parameter; calculation of the rules, based on the adequacy of the model; defuzzification with the transition from linguistic terms to quantitative evaluation; graphical construction of the response surface using a centroid method with determination of the center of gravity of the response surface. The modeling has confirmed that the creation of a heuristic analyzer for determining the quality of wine and the quality of education is appropriate and necessary for preventing the production of substandard products and theprovision of substandard services.
