The object (3) under investigation is projected with different perspectives onto an x-ray image acquisition device. A three-dimensional image is produced from the same object with a second image generation device (2) and a relevant structure (122) extracted. Synthetic two-dimensional images are ...
An x-ray is a procedure fairly easy to comprehend. Discovered in 1895 by German physicist Wilhelm Roentgen, by accident, Roentgen experimented with electron beams in a gas discharge tube and discovered the benefits of seeing the shadow of bones and tissue through the body. Basically the process ...
The present work aims to extend these approaches of identifying descriptors of the spectral features, such as positions of the absorption edge, minima, and maxima, their amplitudes, and curvatures. We present a step-by-step procedure to prepare a training set, evaluate the descriptors, train the...
Contrarily, Idark and IX–ray for an X-ray detector follows Normal distribution, where the sample size n in the electric current measurement referred as the number of digitized current points is typically very large. To establish a proper procedure for the detection limit determination of an X-...

[18,40,41]. Therefore, we tested the relevance of X-ray-based technology for the prediction of the key indicators of peanut produce price, kernel and shell mass. For the first time, we adapted a recently patented procedure building on a 2D-X-ray projection conversion method for biomass ...
ray diffraction (XRD) utilizing a Rigaku Ultima IV diffractometer with a scintillation detector in reflection mode, Cu K{acute over (α)} 19.400 radiation (1.5406A°), Scanning range: 3–60° 2θ, Step size: 0.02° 2θ and Time per step: 1 s, monochromatized with a graphite crystal. ...
ray absorption spectroscopy. For total scattering measurements, a cylindrical quartz capillary with a diameter of 6.5 mm and a wall thickness of 0.5 mm is held in place by a PEEK support not in contact with the primary X-ray beam in order to avoid background signal from the ...
X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies beyond ...
3. Polarization Properties of Magnetar X-ray Emission Both the spectral and polarization properties of radiation emitted from magnetars depend on the physical state of the star surface (whether the solid crust is exposed or covered by a thin atmospheric layer), as well as on the interactions phot...
