Chest X-ray (CXR) images have been one of the important diagnosis tools used in the COVID-19 disease diagnosis. Deep learning (DL)-based methods have been used heavily to analyze these images. Compared to other DL-based methods, the bag of deep visual words-based method (BoDVW) proposed...
The National Renewable Energy Laboratory (NREL) chart shows that third-generation solar cells based on perovskite materials achieved an efficiency of 26.1% in a few years, the same value seen in silicon solar cells with exceptional performance [5]. In addition to the three-dimensional (3D) ...
X-ray machines seem to do the impossible: They see straight through clothing, flesh and even metal, thanks to some very cool scientific principles at work. Find out how X-ray machines see straight to your bones.

A system for detecting the presence of known materials in a body or container. The system incorporates a gamma or X-ray source for irradiating the body with gamma rays to produce X-ray fluorescence of
The image was normalized with respect to data recorded without the chart. In the projection geometry, the focal spot of the optics acts as a secondary X-ray source, and the half-pitch resolution is limited by the size of the focal spot to approx. 5 μm (i.e., to ~Δx/2)....
When a sample’s X-ray diffraction pattern (XRD) is measured, the corresponding crystal structure is usually determined by searching for similar XRD patterns in the database. However, if a similar XRD pattern is not found, it is tremendously laborious to
