Sentence examples for by using first arrival from inspiring English sources

We determined seismic structure models by using first arrival tomography and traveltime mapping.

Since the travel time inversion code of tomo2D uses first arrivals and reflections (e.g., P m P), but does not use later refraction arrivals, we inferred the deeper part of the V p model so as to explain the later arrivals by using the forward modeling method.

The shear wave velocity was estimated using the first arrival method after removing the near field and the crosstalk effects from the output signal.

Identification of the faulty location is carried out by using direction of arrival (DOA) of PD signals.

This is done by first aligning all waveforms on the first arrival using waveform cross-correlations (Fig. 1) and the initial source location is constrained to the epicenter (38.322°N, 142.369E, as determined by the USGS).

We used only P-wave first arrival times, because the phase data for the initial P-wave arrival times are much more accurate than those for S-wave arrival times.

The first 10 s of the data after the first arrival is used and indicated in bright red color.

The P wave velocity model was constructed from both first arrivals and reflected waves by using travel time and amplitude calculations (Figure 3a).

Focal mechanisms of the aftershocks are determined using data of polarities of first arrivals recorded by the OBSs using the program of Reasenberg and Oppenheimer (1985), and 121 focal mechanism solutions were obtained (Fig. 7).

Online scheduling methods address this problem by using only the statistics of energy arrivals.

Finally, simultaneous arrival planning by using a T S Bezier is summarized.
