For a long time, power meters were built using a combination of a base unit and an external power sensor connected via a cable. The RF signal was converted to a voltage signal in the power sensor, ...

In many applications where the input is not under system control but rather connects to the outside world, such as test equipment, instrumentation, and some sensing equipment, it is possible for input ...

Inlet unstart is a particularly critical issue associated with scramjets. That is the upstream displacement or disgorging of the original inlet shock system. Large flow spillage can be caused by the ...

Researchers at the Norwegian University of Science and Technology succeeded in creating light-emitting diodes, or LEDs, on a graphene surface. According to a brief that explains their research, ...

Diode lasers can significantly improve clinical parameters when used as an adjunct to scaling and root planing (SRP) during periodontal treatment, according to a new study in Lasers in Medical Science ...
