I've been in a travelling phase lately.
Secondary data (such as body wave travel times, phase velocity of surface waves, and splitting functions of free oscillation modes) are frequently extracted from the waveforms and are inverted (e.g., Ritsema et al., 1999; Masters et al., 2000; Grand, 2002; Montelli et al., 2004).
Most travel delays (phase two delays) could probably be overcome by a combination of community mobilization and the establishment of emergency obstetric transportation networks (ambulances, etc) linked by an effective communications system that ties the various components of the healthcare system together [ 29- 31].
For applications that needs longer HF phase travel, the use of a rack and its travel length inevitably affect the overall length of the actuation unit, which may be too large to fit into the allocated space.
Since BVMSW modes travel 'backward' in phase, this leads to a negative dispersion.
This fact indicates that the travel time or phase information could be reasonably extracted from our data set.
To the extent that such components can travel at different phase speeds and directions relative to one another, the placement of sensors on the structure can be optimized to best measure the response amplitude.
When GPS navigation system radio waves pass trough the ionosphere and plasmasphere they are subject to delays in phase, travel time and polarisation, owing to the presence of free electrons.
In the pre-diagnosis phase travel to and from health facilities and costs for diagnostic tests accounted for most direct costs (38%and37%7% of pre-diagnosis direct costs respectively).
As the mobile phase travels up the plate by capillary action, the sample dissolves in the liquid, and its components are transported up the plate to new positions at varying distances from the starting point.
