I am interested in simulating a mechanical system, but I don't
have any good books on the subject of simulating analog systems.
If you know of any such books, please send me a reference. I will
send a summary of the results to this list.

[[EDITOR: You might want to try out "Interactive Dynamic System
Simulation" by Granino Korn, McGraw Hill, 1989 -PAF]]

Thank you!

PS: I am not looking for books about simulation packages. I am 
    more interested in books that cover the mathematics of simulating
    analog systems (with an emphasis on doing the simulation on a
    digital computer).

* * *  Announcing the Second Symposium on Behavioral Representation  * * *

PM Trade and the Defense Advanced Research Projects Agency (DARPA) will
conduct the Second Symposium on Behavioral Representation (BR) for
Computer Generated Forces (CGF) on 6 and 7 May 1991 at the University of
Central Florida (UCF) in Orlando, Florida. The symposium will be hosted by
the University of Central Florida Institute for Simulation and Training (IST)
on behalf of PM-TRADE/DARPA. The purpose of the symposium will be:
  - to review a proposed definition of BR in its component elements;
  - to identify research gaps in the component elements of BR;
  - to provide a forum to exchange information on BR and modeling research,
      and its relevance to CGF technology;
  - and to present upcoming research programs and opportunities relating
      to BR and CGF.

Examples of research topics covered by this symposium include:
  - Autonomous Agent modeling
  - Agent Representation
  - and Training Developer Specifications for Automated Forces in Distributed
      Battlefield Simulation

IST Technical Report (IST-TR-90-15) of 15 Aug 1990 titled A TESTBED FOR 
AUTOMATED ENTITY GENERATION IN DISTRIBUTED INTERACTIVE SIMULATION, 
paragraph 1.5 describes the components of a CGF. This report was distributed
at the Initial BR Symposium of 24 and 25 Oct 1990 at Fort Knox, KY.
An electronic copy of this report has been placed on the IST bulletin board
system. Please call (407) 658-5077 to access this system. 

A call for papers on these topics has been issued to those who attended the 
Initial BR Symposium. A limited number of papers have also been invited for 
presentation. The BR Symposium will be organized to provide an opportunity for
attendees to participate in discussions of Uniformed Service User Needs,
Systems Issues, and Technical presentations on the Components of a CGF.

Interested parties should contact:

Hi

 I'm doing some discrete event simulation.  I know that my 
interarrival times are exponential.  I have a huge data and when I fit them 
to different distributions, I'm not satisfied with any particular distribution
as they do not show the peak distribution of packets and off peak distribution
of packets.  I was able to dynamically change the interarrival times of these 
data packets during simulation and was able to generate almost the same shape,
showing peak and off peak points.  It turned out to be the inverse of the 
volumes for each hour.  (I have hourly data). Is it statistically acceptable 
to inverse the volumes for each hour and distribute them exponentially to get 
the volume and the pattern I need ?  Any help would be greatly
appreciated.  Please reply to my personal address also. (our netnews is
flaky !!)

Thanks

 -Krishna

I have recently chosen virtual reality as my topic for a research paper. However
I have not exactly been running into an overabundance of information while
digging around in the library here at O.U. The paper is for a Junior Composition
English course and my target audience is the rest of the class, therefore, I
need to try to keep the terminology somewhat basic and easy to understand.
So far the best material I've found is the OMNI interview with Jaron Lanier
and a couple short articles in New Scientist magazine.  If anyone out there
could help point me in the direction of more sources, or possibly e-mail some-
thing you have on this topic, I would really appreciate it. Thanks.

Hi everybody!

I'm looking for EDIF-Tools, especially a parser or an interpreter.
The reason is that I would like to be able to handle EDIF netlists
with our simulation system.
Does anybody know of an e-mail adress of the EDIF User Group
in Arizona?
I've heard that UC Berkeley has some EDIF tools as public domain
software. Does anybody know of an file-server (preferable anonymous
ftp) where to obtain such software?

Thanks,

    Herbert

Subject: Seeking MODSIM users in Europe for pricing comparisons

Dear Netlanders,
  CERN - European Laboratory for Particle Physics - is currently  evaluating
different simulation tools for its  future developments. We  have been quite
impressed by the capabilities offered by  MODSIM, but not by  its price. The
licence is EXTREMELY espensive compared to other similar commercial products.
We would  like to  know if MODSIM  is used by other European  centers and at
which conditions.

Thanks in advance...
