TRIP Annual Report 1994

This directory contains The Rice Inversion Project Annual Report for 1994 in compressed postcript format. You can either download the entire report in a tar file or you can downlwoad an individual chapter by clicking on the chapter title in the table of contents below.

The 2.1meg tar file of the 1994 report is here.

To display any of the files you should:

  1. uncompress the file by using the command gunzip
  2. use ghostview to display and/or print


  1. The table of contents below is the complete table of contents of the paper report. The only difference here is that paper # 2 is not available in postcript and therefore is not included.
  2. Also, some of the articles had pictures not in postcript format. These (few) pictures are not included.
  3. At the end of the table of contents are three more papers that were completed after the 1994 report was published. The 360K tar file of these papers is here
  4. Problems and/or questions with this can be sent to
