Proportional integral derivative-based aneroid sphygmomanometer testing method
One of the parameters to be tested on the sphygmomanometer is the
deflection of the dial. The testing method based on the standard uses manual air pressure to increase the pressure so that the dial is pointed to the desired pressure. This paper…

Empirical measurement for path loss characteristics at multiple frequency bands from 2.2 to 14.6 GHz in chamber room
Free space path loss (FSPL) is the loss of electromagnetic signal strength.
This loss is caused by the line-of-sight path through free space. Even in a
line of sight (LoS) indoor single layer, as the distance increases, the path loss in the 1 GHz…
