Tiny Black Holes Enable a New Type of Photodetector for High-Speed Data
Tiny Black Holes Enable New Type Photodetector High-Speed Data
2017/4/27
Tiny “black holes” on a silicon wafer make for a new type of photodetector that could move more data at lower cost around the world or across a data center. The technology, developed by electrical eng...
AUTOMATIC MEASUREMENT OF SEWER MAN-HOLES IN LARGE SCALE AERIAL IMAGES
Aerial image automatic measurement coal mining digital photogrammetry
2014/12/30
The geometric changes of the surface (subsidence and horizontal displacement) caused by coal mining can be determined by photogrammetry with a sufficient accuracy. As long time stable targets sewer ma...
