Finally, HRTF-based methods are applicable only to the case of calculating arrival angle in azimuth or elevation [30].
In the American West you can travel hundreds of miles and calculate your arrival time almost to the minute.
In one, it relies on a device's GPS function to deduce the user's location and compare that with train and bus locations to calculate the arrival time to the station closest to the user.
We give explicit fixed point method to calculate these arrival rates in the following section.
We calculate theoretical arrival times of direct S-waves radiating from the center of the largest-slip subfaults in R1 and R2 at the peak time of their slip velocities (Fig. 2c) and plot them in Fig. 5c (blue and magenta lines).
We calculated synthetic arrival time data by adding random Gaussian noises with a standard deviation of 0.05 s (average of 0 s) to the observed arrival time data.
The DDs were calculated from arrival time data picked manually, after corrections for the travel time delays due to the surface sediments.
After calculating the arrival information for each sensor, the iterative algorithm in [15] was used to estimate the 3D hypocenter of the source.
Either of these systems, coupled with Navigate, enables the computer to automatically track the boat's position on its screen, calculating estimated arrival times and compass courses from the navigational equipment.
(The single false negative here represents a calculated shock arrival time that was 30 min off the actual CME arrival time, which meant it was outside of our acceptance range but could factor into later correct SSC detections).
