Subject:      Re: TURBULENCE

There have been two recent postings on this list asking about turbulence and
its connection to scaling and fractals.  There has been active work in this
area by one group that I am familiar with: Shaun Lovejoy at McGill University
and Daniel Schertzer at Meteo Nationale in Paris.  There have been numerous
papers from the group headed by these two, but you must be willing to get
out of the mono-fractal mindset.  The type of non-linear variability that
one finds in geophysical phenomena (atmospheric turbulence, topography,
cloud geometry, earthquake distribution, rainfall distribution, etc) is best
described by a multi-fractal formalism.  There is no one single fractal
dimension that characterizes them.  The good news is that there seems to be
a universality of a sort: there are only three parameters that need be specifie
d in many multiplicative processes.  Using mid-point displacement methods to
generate fractal landscapes is easy and makes pretty pictures, but it is essent
ially at odds (I think) with the multifractal nature of real topography.
     One source of relevant papers is the book "Non-Linear Variablility in
Geophysics", by Schertzer and Lovejoy, Kluwer Press.
     The message is, if you want to describe real things like clouds, fractals
are inadequate.

I really enjoy reading the messages on this mailing list, it beats me having
to go look up a Usenet news conference and finding the new messages.  They
just come "right to my doorstep," as it were.

But one thing that really ticks me off are all the messages asking how to
get off this mailing list.  If all new subscribers would keep the message
from the list server titled, "Your subscription to list FRAC-L," their
questions on this topic would be answered.

Here's an excerpt from the message the list server sent to me when I first
subscribed:

> From: Revised List Processor (1.7c) <LISTSERV@VM1.GATECH.EDU>
> Subject:      Your subscription to list FRAC-L
> Dear networker,
> Your  subscription  to  list  FRAC-L ("FRACTAL"  discussion  list)  has  been

> You may leave the  list at any time by sending a  "SIGNOFF FRAC-L" command to
> LISTSERV@GITVM1. Please  note that this  command must NOT  be sent to  the
> list address (FRAC-L@GITVM1) but to the LISTSERV address (LISTSERV@GITVM1).

So, I sent the following message to listserv@vm1.gatech.edu:

	signoff frac-l

Within a couple of minutes, the list server confirmed my request with this
message:

> From: Revised List Processor (1.7c) <LISTSERV@VM1.GATECH.EDU>
> Subject:      Output of your job "lsloan"
>> signoff frac-l
> You have been removed from list FRAC-L.
> Notification has been sent to the following people:
>  lstsrv-l Dave RE <CC100DR@GITVM1>

Afterwards, I re-subscribed, and I was able to send this message.  If you
did not happen to keep the original mail message that the list server sent,
KEEP THIS MESSAGE.

Now, let's get back to fractals!

  A colleague of mine had what I think is a great idea: why not modify the
LISTSERV program to give prospective subscribers a little test. Instead of
becoming a list member by a simple SUB command, you'd have to convince the
listserv you also know the UNSUB, INDEX, and GET commands. Think of all the
traffic that could be eliminated through this!

  I'm aware that, in the current case, ignorance is not the problem. FRAC-L,
being a nerdier list than most, has less ocomputer-idiot traffic. But I'm sure
we can all think of lists that really need a "quiz-filter"...

For my dissertation, I looked at quantizing the coefficients of the IFS for
a piece-wise linear fractal model.   I found that I could quantize the
contraction factor (vertical) to 6 bits before the attractor would degrade
from what it should be.

In short, the IFS coefficients do not need many bits to do a good job of
reproducing the attractor desired.

This is not a fix on how to get off the list but since so many people are
having trouble with unwanted E-Mail.  There is another solution.

Using an E-Mail filter is the next best thing.

This will allow any messages from unwanted sources to be deleted before you
even recieve them (for all practical purposes).

If this solution is one that someone would like to take.  I am checking in on
the actual procedures.

Please respond if anyone is interested.

Since we are concerned with geometric objects (i.e., fractals) that have
fractional dimensional, it may interest some to read a book not about fractals
but about higher dimensional spaces.  The book _Flatland_ by Edwin A. Abbott,
published by Dover with ISBN 0-486-20001-9 and cost $2.25 was written around
1884 (over 100 years ago) and it's a story about two dimensional square and
his adventures with Lineland (one dimensional space), Pointland (zero
dimensional space), and SpaceLand (three dimensional space).  The story is
very good and it's an eye opener in terms of viewing space.

The book is 103 pages, so it's an easy read and I found it to be quite good.

Just thought some folks may like to hear about it and possibly read it.

And UNPROFOR "leader " gen. L. MacKenzie nickname is "Duke of Chetniks".
(Chetniks are Serbian irregulars, but now all yugoslav Army is called Chetniks)
There were so many cases of UNPROFOR vehicles caught either
smuggling spies - Serbian officers or ammunition to Yugoslav
army, that Canadians who were part of the UNPROFOR are hated by
the inhabitants of Sarajevo. Usually they do not even bother to
answer when allegations with proves were put by the government of
Bosnia. Or they gave stupid explanations. When chetnik officer
Kovacevic was caught with the Colonel ! Gary, they said Chetnik
tricked the poor UNPROFOR Colonel.

It is interesting how the international media coverage is
working. They never said a word about this UNPROFOR role in
Bosnia.

The most logical question is - why they are doing these? Why
helping one side in the conflict, and that is the side who is
condemned as the aggressor by whole world. I can find out two
explanations. They are professional soldiers and there is a
certain solidarity among soldiers. In Bosnia, they feel much
closer to the professional soldiers from the Yugoslav People's
Army then to Bosnian civilians fighting to defend their homes.
Bosnians are not professionals and I can understand that they
annoy UNPROFOR. They feel much better with their own kind,
Yugoslav People's Army. It is a certain professional solidarity
well known from other professions. The only problem is that it's
killing people.

They are getting different services (not necessarily money). As
one of the UNPROFOR soldiers was caught smuggling gasoline, he
stated that the night before Yugoslav army soldiers invited them
to the great party, and he was obliged to return them the
thoughtfulness.

UNPROFOR Headquarters are in Belgrade which is making them even
more cooperative. So actions are coordinated between UNPROFOR and
YPA all the time, on all levels.

It is very interesting that we incline to distrust national armed
forces, but show no doubt in United Nations one. There is a
certain naivety in it. I hope that the wrongdoing of UNPROFOR
forces in ex-Yugoslavia can show us that these armed forces
should be even less trusted as the national one.

I can understand that this writing sounds unbelievable (media
reporting ?), but I thought it might be interesting.

               the society for the philosophy of tools and space


   We are an interdisciplinary and "multinational" organization, small but
growing, dedicated to thoughtful discussion about and research into issues
concerning tools and space.  Currently, we maintain a membership list and
circulate a short newslwetter.  But our future plans call for expansion - a
number of conferences and a journal are possible in the next few years.
Within the scope of our society, members have raised diverse and fascinating
issues for consideration, including but not limited to the following:

- Architectural theory and practice
- Media theory
- Virtual Reality and its impact upon society
- The role of equipment in Heidegger: the tool and truth in _Sein und Zeit_
- Bergson; Levinas and the concept of hypostasis
- Baudrillard & Virilio: speed, the simulacrum and "crystal revenge"
- Marx: from use- to exchange-value; the deterritorializating movement of
  capital and surplus-value
- Deleuze/Guattari: desiring machines, paranoid machines, miraculating
  machines, celibate machines
- The mechanics of the dreamwork in psycho-analysis
- Poetics of space a la Bachelard
- Figural and rhetorical aspects of the tool in literature; the delirious
  machines of Poe, Kafka, Ballard, and Borges
- bolo'o'bolo and other political theories of reterritorialization
- Transit technology and urban planning
- Infrastructure catastrophies: the Chicago freight tunnel flood
- The iconology of computers, especially the Macintosh
- A philosophy of toys
- The tool/toy of language and its (dys)function: the Zen koan, the joke

Now we want what you have to offer...
Membership is free.  Just send your name and address to be placed on our list.

              from"R.Kerr@NEWCASTLE.AC.UK" at Jul 20, 92 5:16 pm

Many moons ago (1978/79 as I recall) I wrote a Simula program that
converted IBM Algol 60 into Simula.  It dealt with almost all aspects of
the conversion, and was used to convert the then current version of the
NAG library in Algol into Simula.  It was done mostly as a feasibility
exercise, but modulo some compiler errors in the then Ibm Simula
compiler it worked correctly.  Since the work was done at Newcastle, Ron
Kerr may be able to dredge it up from archives there, or I can attempt
to retrieve it from a tape that I have.

I have no idea what the current status of the Nag Librarty is in Algol
60, but if it or any similar library exists in Algol 60, then my
conversion program should enable  at least a prototype version to be
generated in Simula.
