In China, we usually drill through coal seams to extract the pressure-relieved gas from the protected layer.
The alphanumeric keyboard (biokeyboard) extracts the pressure template for the password entered.
In addition, if the bottom of the surface borehole is improperly controlled during construction, a lot of gas from the gob is extracted, making it difficult to eliminate outbursts by extracting the pressure-relieved gas.
Proper orthogonal decomposition was developed to extract the main pressure distributions so that the positions where energy converges can be found and the convergence modes can be recognized.
For the IR images, they extract the pen pressure using the first and the second order for some statistical measures such as the following: variance, mean, skewness, kurtosis, energy, and entropy.
The conditional sampling technique is used to extract the wind pressure pattern on the lower and upper roof surfaces when a large total uplift is occurring on the roof.
The vibration response of a thin cylindrical shell excited by fully developed turbulent pipe flow is measured and used to extract the fluctuating pressure levels generated by the boundary layer.
When the surgical maneuver was completed, before the blade was extracted, the perfusion pressure was decreased to physiologic pressure conditions (18 20 mmHg).
Parameters used to extract the turbulent fluctuating pressure levels are determined via experimental modal analyses of the water-filled pipe and measured vibration levels from flow through the pipe at 5.8 m/s.
Three physical signals were taken in the measurements to extract the information needed (gas pressure in plenum, acoustic pressure in liquid, and video record of meniscus motion).
