FRACTAL RADIOPHYSICS. 1. THEORETICAL BASES [PDF]
Radio Physics and Radio Astronomy, 2020 Purpose: Currently, there is a tendency to “fractalize” the science. Radiophysics is no exception. The subject of this work is a review of the basic ideas of “fractalization”, the mathematical foundations of modern fractal methods for describing and ...

On the stark width regularities along the argon isonuclear sequence [PDF]
Serbian Astronomical Journal, 1998 Recent values of the measured spectral lines Stark widths (since 1988) for neutral and ionized argon atoms, have been compared to the values previously predicted by us. These were found from the established regularities of the Stark widths along

Neocatastrophism and the milky way astrobiological landscape [PDF]
Serbian Astronomical Journal, 2008 The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the effects of applying general neocatastrophic paradigm to the evolution of the Galactic Habitable

The expectation maximization algorithm as a powerful tool to solve the stellar membership in open clusters: An application to M67 [PDF]
Serbian Astronomical Journal, 2006 The EM algorithm is a powerful tool to solve the membership problem in open clusters when a mixture density model overlaping two heteroscedastic bivariate normal components is built to fit the cloud of relative proper motions of the stars in a region of ...

Fractional yields inferred from halo and thick disk stars [PDF]
Serbian Astronomical Journal, 2013 Linear [Q/H]-[O/H] relations, Q = Na, Mg, Si, Ca, Ti, Cr, Fe, Ni, are inferred from a sample (N = 67) of recently studied FGK-type dwarf stars in the solar neighbourhood including different populations (Nissen and Schuster 2010, Ramirez et al ...

Monitoring of Space Debris Rotation Based on Photometry
Odessa Astronomical Publications, 2018 The number of spacecraft and space debris (SD) in orbit has become so great that there is a real threat to flight safety. The task of precision calculation of the upcoming positions of any space objects (SO) in orbit in order to predict dangerous mutual ...

Taxonomic Analysis of Asteroids with Artificial Neural Networks
The Astronomical Journal, 2023 We study the surface composition of asteroids with visible and/or infrared spectroscopy. For example, asteroid taxonomy is based on the spectral features or multiple color indices in visible and near-infrared wavelengths.
