Subject: Seeking a Collaborator

I'm seeking a collaborator for a paper I'm working on.

I work in the field of Security and this paper is on analysing firewall
ruleset for problems.

So far I've developed a method where I can display the rules the form as a
digraph (though in reality it really should be a directional hypergraph).
The graph has provided several useful insights.
So far so good, however I've noted that the graph can be taken further to
analyse the ease whereby an intruder can exploit the ruleset to extract
information from within - using adjacency and closed walks - this is where
I start to become unstuck - my math background stops about there...

So I'm looking for a collaborator who is interested in developing that part
of the paper and possibly working towards taking it further (though
developing the closed walks part will probably be enough for this paper)..

Not sure where the paper will be published at this stage I'll probably
submit it to some of the IT Security journals - but we'll see :}

Subject: High Performance Scientific Computation

Technical Session on
High Performance Scientific Computation with Applications

The above technical session is organized in "The 1999 International
Conference on Parallel and Distributed Processing Techniques and
Applications (PDPTA'99)", June 28 - July 1, 1999 Monte Carlo Resort,
Las Vegas, Nevada, USA. (See NA-Digest, V. 98, #49)

Today's scientific and engineering problems demand computational
power which is far beyond that can be provided by conventional
computers. Scientific computations has been one of the most
important components of high performance computation. It is
the initial and continuous driving force behind the development
of high performance computers. The goal of this session is to
bring together researchers in various areas of high performance
scientific computation and applications to exchange ideas and
communicate new developments.

The HPSCA session focuses on the high performance numerical
computation techniques and applications. Anything that is
related to this topic is welcome. Please e-mail Jun Zhang
at if you are interested in presenting a
paper. A web page for this technical session has been created at

where various deadlines and a tentative speaker list can
also be found.

The HPSCA technical session is organized by:

Cornelius Lanczos (1893-1974) was one of the twentieth
century's most versatile and innovative physicists and
mathematicians. His papers cover a vast array of disciplines,
including general relativity, quantum mechanics, scientific
computation, applied mathematics and numerical analysis. The
Cornelius Lanczos Collected Published Papers with Commentaries
(CLCPPC) represents the second part of a two-part celebration
of the life and work of Cornelius Lanczos. The first phase of
this celebration occurred in December 1993 when North Carolina
State University's College of Physical and Mathematical
Sciences hosted the Cornelius Lanczos International Centenary
Conference. [See the Proceedings of the Cornelius Lanczos
International Conference, J. D. Brown, M. T. Chu, D. C.
Ellison, and R. J. Plemmons, eds. (Philadelphia, PA: Society
for Industrial and Applied Mathematics [SIAM], 1994).]

This Collection is the culmination of an eight-year effort
involving 15 editors, 4 translators and 40 other contributors
from departments of physics, mathematics, mathematical
sciences, computer science, electrical engineering,
statistics, multidisciplinary studies and English at
universities and research institutes and centers in the United
States, Australia, Canada, Germany, Hungary, Ireland, New
Zealand, Sweden, Switzerland, and the United Kingdom. This 6-
volume, over 3,200-page library edition is in B/5 format (168
mm x 238 mm) with acid-free paper and handsome hard covers
with gold-stamped letters. The Collection features:

Professional and biographical information about Cornelius
Lanczos (1893-1974)
Excerpts of the Lanczos-Einstein correspondence (1919-1955)
A complete list of Lanczos's publications including his 8
books and their translations
Copies of Lanczos's published papers covering the period
1919-1975 (more than 110 publications including his
dissertation and 47 translations with each page facing the
original language page)
17 introductions to 3 of the 4 Parts and 14 of the 19
Sections in the Collection
Many new and previously unpublished commentaries (including
a foreword) on specific papers of Lanczos and his
contributions to various disciplines.

A detailed description of the organization and contents of the
Lanczos Collection and an order form suitable for printing
with ordering instructions are available on our web page at

In addition to very substantial Institutional support for this
nonprofit project, a considerable volunteer effort was made to
bring it to completion. North Carolina State University (a)
is having the Lanczos Collection printed by a Hungarian
printer, (b) is directly advertising the Collection via email,
fax and mail, and (c) will be distributing it using a local
order fulfillment company. As a consequence, the six-volume
set is very economically priced at only $120 plus shipping and
handling charges of $19 (USA) to encourage widespread
distribution of this important work. Only 500 copies are
being printed to meet the anticipated demand by the world's
largest university research libraries, national research
laboratory libraries and national libraries, by the
contributors, and by many of the 600 participants of the 1993
Cornelius Lanczos International Centenary Conference held at
NCSU. The first three copies will be distributed to the
Library of Congress, The Swiss National Library in Berne, and
the Albert Einstein Archives in the The Jewish National and
University Library at The Hebrew University of Jerusalem,

The major research libraries, the contributors, and the
participants of the 1993 Centennial conference were offered
the opportunity to order the Lanczos Collection last week.
This announcement in the NA Digest offers the Lanczos
Collection to numerical analysts throughout the world and is
the only advertisement that you will receive. An order form
and ordering instructions appear at the end of this

Printing and binding of the 500 sets of the Lanczos Collection
will be completed by the end of January, 1999 and will be
surface shipped from Budapest to Raleigh NC in early February.
North Carolina State University has contracted with the order
fulfillment company, CES Mail Communications of Raleigh, NC
to mail out fliers and to take all orders and receive all
payments for the Collection. Distribution to European
customers will be made from Budapest (beginning in February,
