The most simple example I can think of is the heating system in your
house.  The thermostat kicks the furnace on at some temperature and remains
on until the temperature rises past the setpoint (e.g. one sets the therm.
to 68: the furnace kicks on at 67 and stays on until the temp reaches 72).

The hysteresis in this system reduces on-off chatter of the furnace.  If the
hysteresis was not in the system the furnace would constantly be
switching on and off for short periods of time -- not very efficient.
Hysteresis is a simple method to handle systems that have on/off actuation
only (pretty much most furnaces).

   The space shuttle RCS (Reaction Control System) for on-orbit operations uses
hysteresis to eliminate "jet chatter".  This is a "nice" non-linear phase plane
design controller which keeps the vehicle in a limit cycle, the dead-band for
which varies depending on the mode of operation.  If you have access to a large,
university library then you should be able to find a gugaplex of papers about
this controller.  Perform a keyword search on "shuttle" and "rcs" in the papers
database and I'm certain you'll find more than you need.  If not, get back to me
and I'll try to dredge my memory for a suitable reference.

Well I know of one good example, but it is not quite a real time
solution, but more of a GUI situation. In the project I am currently
working on we display a graphic on the screen which represents
a length of time. The operator can expand this length of time or
shrink it gradually. ( All of the smaller components of the time
period can be changed also but that is not relavent here).

Because the graphic gets too cramped when shrunk it must be rescaled 
ocationally. Now if the operator is trying to adjust the length to be
almost equal to the rescale point then he may get a flicker effect
where the graphic switches between the larger and smaller graphic
several times as he is trying to make this fine adjustment. The
solution is to make the big-to-small rescale happen at a value 
which  is larger than the small-to-big rescale point.

It is kind of hard to explain all that without pictures, but I hope
you get the idea,

From knowedge gained in a previous lifetime as a HVAC tech, this ain't 'zactly
right.

Typical (modern) thermostats have a device called an ``anticipator'' which
amounts to a little heating element that causes the thermostat to ``anticipate''
the overshoot from the controlled system (aka the furnace) and shuts it down
earlier that it would if it waited for ambient to reach the setpoint.  They
also have an adjustment for the ``differential'' (typically a movable magnet)
that adjusts the deadband (hysteresis) around the setpoint.

Whether your thermostat has an ``anticipator'' will generally depend on whether
your furnace tends to overshoot.  Forced-air furnaces and low volume hot-water
furnaces don't have much overshoot and the thermostats for them don't usually
have anticipators.  Steam and gravity-fed hot-water systems usually do.  Almost
all thermostats have a differential adjustment.

I hope I don't get too much heat for this deviation...  ;-)

I think that's the copy with the extra 2 minutes of violence added in that
were cut from the original release.  Basically, some of the violent scenes
are a little longer & more violent.  What more can I say?

The series, which so far has only 13 episodes, was shot in Australia
a few years ago, and is in English.

All 13 episodes will eventually be released on tape. 

13 more episodes are going to be filmed in Los Angeles beginning next 
month.

Hi folks from the movie-backwoods,

Well, Candyman has gotten to us in Germany, too and theres somthing I
wanna ask about it. I have the suspicion that they cut a couple of scenes
(as they sometimes do when they dub films to German), so maybe anyone can
explain the following:

1.) Why was it always talked about, but never so much as shown or otherwise
    integrated into the movie that the first people at the scene of the crime
    always got white hair the same instant?

2.) What is the significance of the house, where Helen lives, having been a
    social development project before like the ones where the Candyman is
    active?

3.) Why is his name "Candyman" and what does it have to do with "Sweets for
    the Sweet"?

Well, maybe Bernard Rose fouled up on these, but they are so obvious that I
am wondering if they cut something here...


Thanx al lot, Ulrich.

I don't think there is any other other official Nick Danger on video.
There is a short (30m) film called "Eat or Be Eaten" on video that is
*wonderful*.  They also have something on video called something like
"Firesign Theater's Hot Shorts" which are old cliff-hanger b&w film
clips stuck together with new voiceover dialog provided by TFT; kind of
fun, but not up to their standards (IMO).  They also did a film version
of "Everything You Know is Wrong", but good luck finding it on video (I
don't think it's ever been released).  Oh yeah, there's also a 30m film
of an edited live performance called "Martian Space Party" that's
probably not available on video either, but used to show up in
repertory cinemas now and again.  And there's also "J-Men Forever" (aka
"The Secret World War") which is an entire movie in the same vein as
the "Hot Shorts" material, entirely by Proctor & Bergman this time,
though, and surprisingly good (better than the "Hot Shorts"); don't
know if it's available on video or not - I think I have seen it for
rent a number of years ago, but may have been hallucinating.

The Nick Danger that someone else mentioned as being on the back of
"How Can You Be in Two Places at Once When You're Not Anywhere at All"
is purely audio.  This is the Marx-Lennon album (Groucho and John,
of course).

Ren-n-Stimpy isn,t bad, but have found that "Liquid Television" (MTV, Tues
@10PM & Sun 11:30PM PCT) is the best that's out there now.  I have seen
some of the same annimated shorts that were in this years "Sick & Twisted

As far as full length movies go, "The Mind's Eye" is excellent!! I highly
recommend it.  A friend of mine dubbed over the original soundtrack with 
a "King Crimson" album (name unknown, recent release though) and it's 
spectacular!!!!!!!!!!!!.  fantastic graphics. ./gb

No, but if the TOWARDS THE FUTURE tapes sell well, there is 
a very good possibility that BOOKS NIPPON will release some of the
