Hi: 
 
  Could anyone please suggest a good reference on real time 
computer simulation of a nonlinear DC motor and gear train?  
I have an ACSL model of the system, and a system block 
diagram in the Laplace domain, but there are many inter- 
connecting paths and three nonlinear functions.  The 
nonlinear functions are modeled as digitized points off 
of a graph, and I plan to interpolate into them.  
 
  The simulation is being written in BASIC, ugh.  At least 
its HP BASIC.  Some IO is being performed.  
 
  I am planning to calculate the current state of the system 
through all the paths up to each integrator, then perform a 
simple Euler integration, and loop in this manner.  It seems 
like a Runge-Kutta would consume too much time.  Accuracy 
in the simulation would be paramount, but time is of 
general concern. 
 
  If anyone could suggest a reference, or give a tip, or 
suggest a better approach I would greatly appreciate it. 
 
Thank you,

I would like to request information regarding European simulation
research, particularly with regard to the Airbus program.  All of
my research sources begin and end with North American efforts,
which I do not believe exhaust the field.  Thank you for any leads
you may supply.

       International Workshop on Principles of Diagnosis
	  Menlo Park, California, July 23-24-25, 1990

			Call for Papers

This workshop encourages intensive and high quality interaction
and cooperation among researchers with a diversity of artificial
intelligence approaches to diagnosis.  Attendance will be
limited to thirty participants, with fifteen presentations
spread over three days.  Substantial time will be reserved for
discussion.

To attend, participants should submit extended abstracts or
short papers to be reviewed by the committee.  Submissions are
welcomed in the areas of:

- Approaches to modeling and diagnosing both engineered and
  natural systems, especially analog and large scale systems

- Theoretical aspects of deductive and abductive diagnosis

- Strategies for controlling diagnostic reasoning to prevent
  combinatorial explosion

Please limit your submissions to 3000 words.  Accepted papers
can be revised and expanded for compilation and distribution to
the workshop participants.  Although work published elsewhere is
acceptable, new original work is preferred.

Please send four copies of each submission to the chairman at
the postal address below.  Please include several ways of
contacting the principal author in addition to a postal address:
electronic mail addresses, FAX, and telephone numbers are
preferred, in that order.  Please indicate with your submission
whether you wish to make a presentation or only to attend; in
the case of multiple authors please indicate which authors wish
to participate.

Submissions received after 30 March 1990 will not be considered.
The decisions of the committee will be mailed 25 May 1990.
