We merged DustTrak and Palm date and time stamps and GPS geographic coordinates to identify the measurements taken at each stop along the monitoring path.
Because GPS units measure true location with error, GPS coordinates were "snapped" to the nearest point on the monitoring path; the location of the path was ascertained using a Trimble GeoXT GPS unit (Trimble Navigation Limited, Sunnyvale, CA, USA) with a nominal error of < 1 m.
In our measurement campaign, the geometric means of PM2.5 and PM10 along the mobile monitoring path were 21 and 49 μg/m, respectively, in the neighborhood with highest SES and 39 and 96 μg/m, respectively, in the neighborhood with lowest SES and highest population density.
This is because that SCTP- Rev + uses the receiver-based sending rate estimator and receiver-assisted path handover trigger to monitor per-path sending rate and adaptively select an optimal primary path for data delivery.
SCTP marks each newly created path as "active" and applies the error count to monitor the path condition.
In path coverage, for example, the network is in charge of monitoring a path and discovering any intruder trying to cross it.
Eventually, all hurricanes with the potential to strike the shore may have their paths monitored in this way, Dr. Black said.
At the command center inside the Department of Health and Human Services, a skeleton crew, including military personnel and Red Cross workers, was monitoring the path of the storm into the night.
The people are more credible when it comes to determining the right direction, and today they are able to monitor the path of transition and are capable of expressing their opinions whenever they sense a deviation from the right track.
As Republican lawmakers monitor the path of the lawsuits challenging Mr. Clinton's authority on several fronts, some members of Congress and industry officials expect the Bush administration to appoint officials at the Justice Department and other agencies who would coordinate a full-throttled attack against the last-minute Clinton environmental measures.
