Subject: Category Theory in AI
Some of us here at Philips Laboratories are using universal
algebra, and more particularly category theory, to formalize
concepts in the areas of representation, inference and
learning. We are interested in finding others who are tak-
ing a similar approach. If you are already working in this
area, please respond by email or USmail (please do not
post), so that we can form an informal network, and inter-
change information.

I'm familiar with those areas of AI, but not with category theory (or
universal algebra, for that matter). Can anyone give a short summary for
the layman of those two mathematical topics? And perhaps a pointer as to
how they might be useful in formalizing certain AI concepts. Thanks!

Do you know of any Ada Expert System Shells currently available (either
Public domain or commercial)??
Please reply directly to me as I normally do not monitor this list. If there
are sufficient replies I will summerize for the list.

############################################################################
I am looking for {references | names | addresses | phone numbers } of people
who have developed {expert | intelligent knowledge-based | decision support}
systems in the area of diagnosing plant diseases. Can anyone help ?
I am familiar with the soy bean work of Michalski et al, but know of nothing
since then.
With thanks

Subject: Looking for a Cognitive Science Society
Hello,
I'm posting this request for a friend who doesn't have net access.
Is there any Cognitive Science Society? If so, what is their address, either
e-mail or snail, and what do they publish, and how often?
thanks very much,

Subject: IEEE Conf. on AI Applications (CAIA) 1989 ?
Is anybody out there knowing whether the
IEEE Conference on Artificial Intelligence Applications (CAIA)
will be held in 1989 ? If there will be a CAIA again in 1989,
what is the deadline for the submission of papers?
The 4th CAIA has been held March 14-18, 1988 at
Sheraton Harbor Island Hotel, San Diego, California, and
has been sponsored by 'The Computer Society of the IEEE'.
I couldn't find any announcement or call for papers for a
5th CAIA in the June-1988-issues of both 'Comm.ACM'
and 'IEEE Computer'.
Sorry for this posting if I have missed a message about that.
Thanks in advance,
Gerhard Fleischanderl

Subject: Camera Stabilization
I am looking for information on camera stabilization and sensors for
this purpose suitable for moving vehicles. In particular
could you please answer the following questions:
1) What is the Steadicam Gyro? How can I find one?? How does it work???
2) What is Sorbothane shock mounting?
3) What are accelerometers and rate gyros? Any suppliers??
Any other related information would be grately appreciated.

The Steadicam (TM) is a device used by professional movie photographers
when it is necessary to photograph with a hand-held camera but high stability
is required. It consists of one or more gyros on poles, attached to a harness
worn by the cameraman. It is rather expensive, for no good reason, is patented,
and is not particularly useful for autonomous vehicle operation.
>2) What is Sorbothane shock mounting?
Sorbothane is an interesting material used for gymnastic mats and such.
It's a soft plastic with some of the properties of a liquid.
[The only other place I have seen it used is as shock-absorbing
pads in (somewhat expensive) bicycling gloves. -- nick]
>3) What are accelerometers and rate gyros? Any suppliers??
ETAK, Inc. (Menlo Park, CA USA) is coming out with a low-cost two-axis
rate gyro in a few months. Expensive ones can be obtained from makers of
military and aircraft navigation equipments. I suggest you read up on
inertial guidance and aircraft autopilots before acquiring anything.
Panasonic showed a gyroscopically stablized consumer-grade camcorder
at the Consumer Electronics Show this summer. It should be available at
Japanese retailers by the end of the year. This may be a promising approach.

Subject: simple ES tools for the Sun
I am looking for a very simple Expert System development tool for a Sun 3
running Franz Lisp. I don't want anything terribly expensive or terribly
complex. The systems that I write will probably eventually be ported
elsewhere, so I don't plan to anything very exotic that might be difficult
to port. Public domain stuff is acceptable if it's not *too* buggy.
Does anyone know of something suitable? You may reply directly to me.
Thanks,
Charlene Hefley
