The monitoring of space debris is important for spacecraft such as satellites operating in orbit, but the background star images taken by ground-based telescopes relatively complex, including stray light caused diffuse reflections from celestial bodies Earth or Moon, interference clouds atmosphere, etc. This has a serious impact on dim and small targets. In order to solve problem posed complex ...

Abstract We report measurements of the angular distributions low momentum atmospheric muons at 38 m above sea level for zenith angles θ between -60 and 60 degrees in south-north direction. The muon detection was performed with two NaI(Tl) scintillation detectors mounted coincidence. An adjustable lead thickness placed allowed to select a minimal ranging from 0.3 0.9 GeV/c. integrated differenti...

Severe geomagnetic storms appear to be ordered by the solar cycle in a number of ways. They occur more frequently close maximum and declining phase, are common larger cycles show different patterns occurrence odd- even-numbered cycles. Our knowledge most extreme space weather events, however, comes from spikes cosmogenic-isotope ($^{14}$C, $^{10}$Be $^{36}$Cl) records that attributed significan...

Air pollution is a challenging issue in some of the large cities in developing countries. Air quality monitoring and interpretation of data are two important factors for air quality management in urban areas. Several methods exist to analyze air quality. Among them, we applied the dynamic neural network (TDNN) and Radial Basis Function (RBF) methods to predict the concentrations of ground-level...
