ERRATUM

Due to an unintended mistake, on the conference CD, article RO-029 appears as "not presented"
while, in fact, was presented by Proffessor R. G. Ripeanu.
We would like to appologize and correct this mistake by placing a link to the article here.
The article can also be found on the conference CD in the folder "PDF-uri", file name "029.pdf"
Sorry for the inconvenience.

Because of a similar mistake, paper RO-123 presented by prof. V. Dulgheru in Session S4 (Tribology of Machine Elements)
has been omitted from the content of the CD. However, this paper can be found under the name "123.pdf"
in the CD folder "PDF-uri".
