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.Документ Effectiveness of artillery systems(Національний технічний університет "Харківський політехнічний інститут", 2018) Aliev, A. A.; Bayramov, A. A.; Sabziev, E. N.The essence of the problem of artillery system effectiveness factors determination has been disclosed in the paper. On the base of the hypothesis of presentation possibility of effectiveness factors of artillery systems as linear combination of performance characteristics, the method of effectiveness factors calculation for the new artillery systems of the same category it has been offered. By this model using the effectiveness factors for the several artillery systems have been calculated, by compare of obtained data with their effectiveness factors, the adequacy of constructed mathematical model has been shown. At the same, with purpose of investigation of the "discrepancy" between the linear combination coefficients and the influence feature on effectiveness factor of relevant performance characteristic, the correlation between performance characteristics and the correlation between each performance characteristic and performance characteristic have been investigated, also Pirson’s linear correlations coefficients have been calculated. The efficiency coefficient dependence on battle characteristics (artillery firepower, mobility, durability and applicability) and on the performance characteristicshas been modelled. The "discrepancy" in the signs and the values of the performance characteristics coefficients has been explained by various impacts on the combat characteristics of artillery sets.
