Monitoring forest health typically relies on remote sensing tools such as light detection and ranging (LiDAR), radar, and ...

The vast majority of audio editing and processing is performed in the time domain: we specify a time range and then apply edits or processes to the audio that falls within it. There are tasks, though, ...

LEAD sulphide photo-conductive layers are now known as sensitive detectors in the near infra-red 1, but so far their usefulness has been limited to wave-lengths less than about 3 µ.

MICROCRYSTALLINE layers of lead telluride can be made which show photo-conductivity when illuminated with infra-red radiation. Such layers are similar to the better-known lead sulphide and lead ...
