Sentence examples for determination of focal from inspiring English sources

Distant stations, where seismic rays are near vertical, contribute mainly to the determination of focal depths.

The local velocity models play an important role in the location of local events and the determination of focal mechanisms.

This paper proposes a modeling approach that includes modeling the grain orientation of the welds with buttering, calculating the ray path for the determination of focal laws, and applying the linear phasing multi-Gaussian beam model in order to focus the ultrasonic beams produced by a phased array transducer mounted on a wedge contacted to the interrogated DMW.

The optimization of the excitation path as well as the determination of focal volume properties needs bright and photostable reference samples with a known diffusion coefficient.

Critical to this task is the determination of the "focal region".

We present a method that allows the repeatable determination of the focal ratio degradation properties of optical fibers.

The OBSs were equipped with three-component 4.5 Hz geophones and hydrophones (Takahashi et al. 2015) and were placed about 10 km apart on the seafloor to allow determination of the focal depths of shallow microearthquakes along the NAF.

Consequently, there are two types of imprecision that affect the determination of regions of focal alteration.

The velocity structure used in the determination of hypocenters and focal mechanisms are shown in Fig. 4, which was modified from "Uji model" in order to stabilize the hypocenter depths and focal mechanisms of shallow earthquakes.

Seismic signal communication incorporates the time needed for the determination of the earthquake focal parameters, t SD, and the time needed for the tsunami decision-making, t TD, as well as the time, t ST, needed for the transmission of the earthquake information and of the result of the tsunami decision to the operational center of the civil protection.

This way, the elimination of the time needed for the determination of the earthquake focal parameters, t SD, and the time needed for the tsunami decision-making, t TD, through automation and direct coupling with the IEEW, would reduce the total time needed to generate the alert to close to 1 min.
