In this paper, the radio propagation characteristics are studied in the high-speed maglev millimeter wave communication system. Based on the ray tracing technology, studies the influence of antenna ...

Ultrasound computed tomography (USCT) is a promising technique for breast imaging. It provides three modalities: echo image, sound speed image (SSI), and attenuation image. The echo image reveals ...

A recent uptick in battery-related fires has drawn attention to the challenge of identifying defects that can cause these ...

The flame propagation speed is significantly accelerated in the coal dust after soaking. After the spark ignition, the coal dust on the tube wall is instantly ignited, showing a discrete distribution ...
