Absorption lines with high blue-shifted velocities are frequently found in the ultraviolet (UV) and X-ray spectra of luminous active galactic nuclei (AGNs). This implies that high-velocity winds/outflows are common in AGNs. In order to study the form

A hot corona is suggested to be above the standard thin disk. The anisotropy of hard X-ray emission in radio-quiet active galactic nuclei implies that the corona is not static and probably moves outwards like winds. We perform two-dimensional magneto

We analyze multifractal properties of low (LLSFNs; = 50 degrees), full-disk (FDSFNs; 0 degrees similar to 90 degrees) solar filament numbers (SFNs) and international sunspot numbers (ISNs) by estimating characteristic parameters (alpha(0), Delta(alph

On the basis of the Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, we measure power spectra of detrended full-disk (FSFNs, latitudinal bands: 0∘–90∘), low-latitude (LSFNs, latitudinal bands

The paper establishes emergency recovery maneuver model of six degree of freedom and blowing ballast compartment model of high pressure air. Based on standard maneuver equation, considering the influence of large angle of attack to hydrodynamics coef

After flooded compartment of submarine, whether or not success of emergency recovery lie on the size of crevasse, the depth and the speed of submarine, and the emergency recovery mode. The paper explains the method of making certain submarine safety

Observations show that winds can be driven from the innermost region (inside a 50 Schwarschild radius) of a thin disk. It is interesting to study the winds launched from the innermost region. A hot corona above the black hole (BH) thin disk is irradi
