Example of Application of GIS on Public Health

Last week, we had 7 people attended the training class of spatial analysis. Seems a lot of people are interested in this area. Attached please find a 4 years old project I involved about 'Temporal and spatial relationship of ozone and asthma'. One thing amazed me by GIS is geostatistics (maybe only thing, sorry), which can convert values among point, line, and area.

How to send and receive large files through the Internet

There are several websites can send large files to our friends. One of them is TransferBIGFiles.com, a free service for sending and receiving large files through the Internet. No registration is needed to use the service. View a simple diagram of how the service works.

After you upload the file (up to 1GB), the recipient gets an email with a link to download the file. The file is good for 5 days or 20 downloads, whichever comes first. The optional settings let you add a note to the email, password protect the file and get an email confirmation of the download.

The folks behind the site share their experience in building TransferBigFiles.com in one weekend. Check out the statistics showing the number of transfers, file size, bandwidth and other interesting stats.

Statistical Graphics Using ODS

http://support.sas.com/rnd/app/da/stat/odsgraph/

Graphics are an invaluable tool for data analysis, where one image can summarize pages of output. Graphics reveal patterns, point out differences, and provoke meaningful question about your data. SAS 9.1 now includes an experimental extension to the Output Delivery System (ODS) that provides high-quality graphics along with tabular output for many statistical procedures.

ODS Graphics gives you convenient access to commonly used graphics for a particular analysis. You no longer need to export your results to other graphical tools. With simple ODS commands and procedure options, you can generate the boxplots, scattergrams, and residual plots you need as well as several dozen other types of graphical displays. You can choose from several styles, or you can customize your graphics. You can direct the graphics to destinations such as HTML, RTF, and Postscript.
