 IEEE PDF eXpress is a free service to IEEE conferences, allowing their authors to convert DOC files to PDFs.

   First-time IEEE PDF eXpress users should do the following:

  1. Go to the IEEE PDF eXpress site after 30th of September 2021.
  2. Click the "Create account" link.
  3. Enter the following:
  • Conference ID: 53156X

  3. The new PDF file should contain the phrase "Certified by IEEE PDF eXpress at [date_and_time_of_conversion]" in the Document properties Application field
   Previous users of PDF eXpress need to follow the above steps, but should enter the same password that was used for previous conferences. Verify that your contact information is valid.

IEEE PDF eXpress is not a manuscript-collection system and does not replace the conference's submission system. Once authors verify that they have IEEE Xplore-compatible versions of their manuscripts,
they will still need to upload the files to the Conference Management System.

 The papers that are not formatted according to the above templates and/or are not submitted by the deadline will not be included in the proceedings.

 The paper should be reported personally by one of the authors. For the oral presentations it is suggested to use MS PowerPoint. A multimedia projector is available.


The presentation is prepared using the template file above. The number in front of the paper title is taken from the final program.
