Update to real-time RDAHMM portlet
We have changed the coloring plan of markers in the real-time RDAHMM portlet, so that now the colors describes the state change information about each station, rather than which network they belong to. Now we have three different colors: red for state change within last 2 hours, yellow for state change within last 1 day, and green for no state change within last 1 day.
We use red for last 2 hours because there is a lag between the time stamp of the real-time data and the "current" time when the data is received. For example, at 14:10pm, we might just receive a station's gps data with a time stamp of 13:05. Therefore, the evaluation results of a station always show its state change information of an hour ago or so.
In order to expose the state change information to the portlet, the real-time RDAHMM service saves this information for each network in a separate file in the same directory as the plots, so that the portlet can retrieve them with URLs.
Check out the new portlet at http://gw11.quarry.iu.teragrid.org:8080/gridsphere/gridsphere.

Video making added to Daily RDAHMM
We have integrated the video making function to daily RDAHMM service and portlets.
The service will now create a new thread to make a video of the whole time period after doing RDAHMM analysis on all stations, and add an xml element into the result xml file, which gives a URL of the newly created video.
The portlet will show a link to this video, right below the link to the trace file of each day's number of stations with state changes.

Plot of state change numbers added to Daily RDAHMM
A new plot function is added to the daily RDAHMM service. After doing RDAHMM analysis on all stations everyday, the service will draw a plot to display the variation of the number of stations with state changes through the whole time from 1994-1-1 to "today". We added new shell and gnuplot scripts to do this, and the service will generate a file containing the trace of the state change numbers as the input for these scripts.
On the daily RDAHMM portlet, a new tab is added to show this plot, as well as a link to the trace file, which contains the detailed information about each day's number of stations with state changes.
