FRACTAL ANALYSIS OF THE EARTH TOPOGRAPHIC MODELS USING MULTI-PARAMETRIC HARMONIC ANALYSIS

(STEF92 Technology, 2017-06-20, Yury NEFEDYEV)

Show more

The study of the Earth's topographic models has been conducted on the basis of fractal analysis. The mean values of fractal dimension for the Earth's surface on longitudes and latitudes are obtained. It is well known that self-similarity is inherent to many natural objects and space systems; this is why they can be described with fractal dimension пїЅ quantitative measure of geometric complexity of a set (an object). Determining fractal dimensions of different objects allows studying not only their structure but p...

THE METHOD OF ASTRONOMICAL REFRACTION ANOMALIES ANALYSIS BASED ON AEROLOGICAL DATA

(STEF92 Technology, 2017-06-20, Sergey Demin, Alexey Andreev, Natalya Demina, Yury Nefedyev)

The aim of this article is to study astronomical refraction anomalies. Back in 1925 Grachev and Banahevich found systematic errors in meridian observations depending on zenithal distance. Grachev suggested that these refraction anomalies arise from the inclination of the Earth's surface to the South. The airstratas of the same density were considered as parallel to the Earth's surface. But the analysis of latitude observations from the Bamberg and ZTL-180 telescopes showed there were significant systematic errors ...

THE METHOD OF MOONQUAKES SELENOPHYSICAL PARAMETERS ANALYSIS

(STEF92 Technology, 2017-06-20, Yury Nefedyev)

Show more

The purpose of the present study is to apply the new methods of multi-parametric analysis to moonquakes. It should be noted such physical phenomena as moonquakes are some kinds of complex systems. As the works in which analysis of moonquakes observations is conducted have shown, lunar seismophysics is much more complex process than Earth's geophysics. This is why to study the physical nature of moonquakes and their parameters it is necessary to use methods of statistical physics and robust estimates. Currently, th...
