Документ The problem of redistribution of radio frequency used in the organization divisions(Національний технічний університет "Харківський політехнічний інститут", 2021) Pashayev, Adalat Bakhtiyar; Sabziev, Elhan Nariman oglu; Hasanov, Arif Hasan oğluThe problem of radio frequency distribution is considered in the article, taking into account the regulations and geographical location of the operating units. The problem of assigning radio frequencies from among those assigned for corporate use is studied. Using conformal mapping, it was substantiated that any territory can be divided into zones, each of which will have a border with only three other zones. In this case, in each zone, you can assign frequencies in the amount of one quarter of the total number of available frequencies that do not overlap with frequencies assigned to adjacent zones. A mathematical model of the problem of radio frequency redistribution has been built, taking into account the regulations and the geographical location of the units. The implementation of algorithm allows taking into account the history of frequency distribution by zones, which allows you to completely update the used radio frequencies for a new period of operation. A software module has been compiled that generates frequencies at random from those available for assigning corporate use for each zone. The software module allows fast and frequent reallocation of frequencies by zones, thereby ensuring the safety, reliability and stability of communication between organizational units.Документ Fuzzy diagnostics of soils according to the World Reference Base for Soil Resources(Національний технічний університет "Харківський політехнічний інститут", 2020) Hasanova, S. A.; Pashayev, A. B.; Sabziev, E. N.Soil classification remains one of the most controversial topics in the world soil science because of differences in the principles underlying it. As of today, many countries have developed and use their own national classifications. Since scientific classification facilitates successful investigation and proper use of soils, the issue arises of representation of one classification in another. In the paper the possibility of applying fuzzy technologies to soil diagnostics based on the World Reference Base for Soil Resources is considered. A trapezoidal form of membership functions of the parameter set of diagnostic horizons is proposed. The algorithm of fuzzy diagnostics is presented on the basis of the proposed functions. Conclusion. The paper proposes a fuzzi fication mechanism for the set of indicators of diagnostic parameters and describes the algorithm of the system of fuzzy inference about the identification of the values of the corresponding parameters in accordance with the compositional inference rule. Thus, the effectiveness of the use of fuzzy technologies in soil diagnostics by the World Reference Base for Soil Resources is demonstrated.
