This paper proposes two strategies for combining the information from the stations: i) combining the features extracted from the signals from each station and ii) combining the classifiers of each station.
Here link i is defined as the section between stations i − 1 and i, and link i includes station i.
The theoretical travel time difference (Δt i,j ) is computed for each pair of stations, i and j, using the difference in S-wave travel times from the hypocenter (x, y, z) to the stations (i, j) considering the one-dimensional velocity structure.
The matrix Y n is defined by (3) where R n,im is the resistance of the conductor between stations i and m (i, m = 1, …, N). (If stations i and m are not directly connected by a conductor, R n,im naturally gets an infinite value).
Consider the case in which adjacent two stations i and j observe earthquake k, where the hypocentral distances of each station are long compared with the distance between the stations.
It includes only the lines I ride and the stations I frequent.
With the first three radio stations I programme my own music.
Although I was in one of the world's busiest railroad stations, I never heard a train.
If the train stops between stations, I want to know for how long, and possibly why.
Without Safe Stations, "I really don't think I would have made it this far," she said.
"For some reason with the black stations I don't hear what I want to hear," she said.
