Efficiency of the Least Squares Support Vector Regression in Local Modeling of the Ionosphere Total Electron Content and Comparison with other Models [PDF]
فصلنامه علوم و فناوری فضایی, 2023 In this paper, we aim to employ the least squares support vector regression (LS-SVR) for the spatio-temporal modeling of the ionospheric total electron content (TEC).

Strategies for optimizing the single GdSrFeO4 phase synthesis
Open Chemistry, 2023 This work provides data on strategies for single GdSrFeO4 phase solid state synthesis. Earlier works have shown that under the solid-state synthesis conditions, the GdSrFeO4 preparation is hampered by the formation of non-target product: Gd2SrFe2O7. This

Bessel’s method in study of solar eclipse influence on the ionosphere
Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2023 Relevance. A solar eclipse is a global disturbing factor that significantly changes the characteristics of the ionosphere. As is known, the ionosphere affects the propagation of radio waves of all ranges, that is, it affects the operation of navigation ...
