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, Greg Harrison (904)239-2048 My opinions are not intended to reflect those of GE. ------------------------------ To: uunet.uu.net!comp-simulation@lll-crg.llnl.gov Path: well!bluefire From: well!bluefire@lll-crg.llnl.gov (Bob Jacobson) Newsgroups: comp.simulation Subject: Inquiry regarding 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. -- BOB JACOBSON, Associate Director, Human Interface Technology Laboratory University of Washington (FU-20), Seattle, WA 98195 USA (206) 543-5075 (voice), 543-5380 (fax) * bluefire@well.uucp >> "We can do virtually anything." << ------------------------------ Date: Mon, 8 Jan 90 09:56 PST From: Walter Hamscher <pwtc!hamscher@labrea.stanford.edu> Subject: Diagnosis Workshop To: simulation-request@ufl.edu ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 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.
