Cycle counting improves on the original path failure detection method in a ... changed from “inactive” to “active.” The SCTP original path failure detection mechanism must take continuous packet timeouts to reach the inactive threshold.

While these results are not surprising from a brain anatomy standpoint, it ... Values close to +1 and -1 indicate brain areas of importance for classifying EEG data into idling and dorsifiexion classes. Since our feature extraction mapping is piecewise linear, there...
