CLIMATOLOGY OF ATMOSPHERIC SOLAR TIDAL MODE EFFECTS ON IONOSPHERIC F2 PARAMETERS OVER THE AMERICAN SECTOR DURING SOLAR MINIMUM BETWEEN CYCLES #23 AND #24

This work presents the contribution of solar atmospheric tides (diurnal, semidiurnal, and terdiurnal modes) to the variability of the parameters critical frequency (foF2) and peak height of the F2-layer (hmF2) in the American click here sector during the transition of solar cycles #23 and #24, a period considered one of the lowest solar activities

Image processing is an effective method for characterizing various two-phase gas/liquid flow systems.However, bubbly flows at a high void fraction impose significant challenges such as diverse bubble shapes and sizes, large overlapping bubble clusters occurrence, as well as out-of-focus bubbles.This study describes an efficient multi-level image pr
