James S. Albus, Hui-Min Huang, Elena R. Messina, Karl Murphy, Maris Juberts, Alberto Lacaze, Stephen B. Balakirsky, Michael O. Shneier, Tsai H. Hong, Harry A. Scott, Frederick M. Proctor, William P. Shackleford, John L. Michaloski, Albert J. Wavering, Thomas Kramer, Nicholas Dagalakis, William G. Rippey, Keith A. Stouffer, Steven Legowik
The 4D/RCS architecture provides a reference model for military unmanned vehicles on how their software components should be identified, organized, and interacting such that missions, especially those involving unknown or hostile environments, can be

Tying Together Design, Process Planning and Machining with Step-NC Technology

June 13, 2002
Author(s)
Frederick M. Proctor, John L. Michaloski, William P. Shackleford
While simulation has been successful in tying design and process planning into an iterative loop, machining has traditionally been a downstream terminus of the manufacturing cycle. Simulation of machining has proven difficult due to the highly dynamic and

Timing Studies of Real-Time Linux for Control

April 1, 2002
Author(s)
Frederick M. Proctor, William P. Shackleford
Linux is being used increasingly for real-time control of industrial equipment. Versions of Linux adapted to support deterministic task execution are freely available. The resolution of task timing is much higher than for typical user-level processes, on
