Ebo: You may be thinking of this 2001 SPIE paper: Frederick M. Proctor and William P. Shackleford, "Real-time Operating System Timing Jitter and its Impact on Motor Control", Proceedings of the SPIE Sensors and Controls for Intelligent Manufacturing II, Vol. 4563, pp. 10-16, October 28, 2001. Nevermind the SPIE paywall. NIST provides a pdf copy at http://www.nist.gov/customcf/get_pdf.cfm?pub_id=824455 This is the work I alluded to in my earlier email.
