Enhanced colour encoding of materials discrimination information for multiple view dual-energy x-ray imaging [PDF]

open access: yes, 2009
This thesis reports an investigation into dual-energy X-ray discrimination techniques. These techniques are designed to provide colour-coded materials discrimination information in a sequence of perspective images exhibiting sequential parallax.

Effect of Time-varying X-Ray Emission from Stellar Flares on the Ionization of Protoplanetary Disks

open access: yesThe Astrophysical Journal
X-rays have significant impacts on cold, weakly ionized protoplanetary disks by increasing the ionization rate and driving chemical reactions. Stellar flares are explosions that emit intense X-rays and are the unique source of hard X-rays with an energy ...

GECAM discovery of a peculiar magnetar X-ray burst (MXB 221120) from SGR J1935+2154 associated with a fast radio burst

open access: yesAstronomy & Astrophysics
Fast radio bursts (FRBs) are enigmatic cosmic transients of millisecond duration observed in the radio band. The identification of FRB-associated magnetar X-ray bursts (MXBs) from the galactic magnetar SGR J1935+2154 suggests that at least a fraction of ...

Analisa Difraksi Sinar-X pada Baja Tahan Karat Austentitik dan Feritik (Uji Laboratorium)

open access: yesJournal of Dentistry Indonesia, 2015
X- rays with wavelength in the range 0,5 to 2,5 Å, have a very short wavelength compare to the visible light wavelength in order of 6000 Å. Therefore, x-rays can be used for determination of the finest structure of materials by using the x-rays ...
