The team also added that the fibers can distinguish between the two types of earthquake waves, the P-wave
and the S-wave.
It was characterized by increased amplitude of p-wave
A 12-lead electrocardiography revealed sinus rhythm with the left axis deviation of the P-wave
and normal PR interval without PR segment.
We especially bring the P-wave
detection (atrial activity) to a whole new level, which explains our radically better PPV, said Fleureau.
This information needs to be completed with back azimuth usually derived from P-wave
polarization or S-wave polarization (Eisner et al.
Using dense array data from several hundred stations, P-wave
records are typically backpropagated to the source region with a reference 1-D Earth structure.
However, due to the small scale of the fault and the appear wave impedance difference between coal seam and surrounding rock (the average density and P-wave
velocity of coal seam and surrounding rock are respectively as: [rho]1=1400Kg/m3, V1=2000m/s; [rho]2=2800Kg/m3, V2=3500m/s), the obvious diffraction could be formed in the process of seismic advanced detection in coal roadway, as shown in Figure 2.
changes are saved as the catheter approaches the SVC, helping to identify the lower 1/3 of the SVC, near the CAJ, eliminating the need for confirmatory chest X-ray or fluoroscopy in adult patients.
The ECG examinations revealed no differences between the baseline and post-sedation values for P-wave
, R-wave,or T-wave amplitude or QRS duration (Table 1).
A 2-D coordinate system (x,y) is constructed in which the wave normal of the p-wave
(in-plane longitudinal wave) and s-wave (shear wave) lie.
Generally, it can output stress-strain curve, S-wave, and P-wave
velocity is determined based on a complex set of material properties, such as the mineral compositions, porosity, pore fluid characteristics, and pore structure [41-43].
