Subject: A Double Series

In signal processing applied to computer music, the following power spectrum P
corresponds to a modified FM (Frequency Modulation) algorithm using two opera-
tors in "cascade".
+inf. +inf. 2 2n 2k
P(r ,r ,x ,x ) = SUM SUM ( J (x ) J (nx ) ) r r
1 2 1 2 k=-inf. n=-inf. n 1 k 2 1 2

where J (x) is the cylindrical Bessel function of order n.
n

When x =0 , the power spectrum is reduced to the single sum:
2

+inf. 2 2n
SUM (J (x )) r = I (x (r -1/r ))
n=-inf. n 1 1 0 1 1 1

where I is the modified Bessel function of the first kind of order 0.
0

Is it possible to write P in a closed form? In general (r ,r !=1) or in some
1 2

particular cases (r and/or r =1).

Subject: Fredholm Equations of First Kind

Does anyone have a routine to solve the Fredholm equations of the first
kind? I have no idea what this is, someone just wants me to ask the net.
Please respond directly to me, as I am not a subscriber to this mailing list.
Thanks in advance

Subject: IEEE Floating Point Routines

I'm looking for code to add/subtract/multiply/divide IEEE format
floating point numbers on a 32-bit integer processor. Speed is not
critical. Only single precision is required. Double precision and
full conformance with the IEEE standard are desirable, but optional.

Language preference is 1) C, 2) other HLL, 3) NS 32000 assembly.

Any code or pointers will be appreciated.

Subject: Bill Pell

You may already be aware of the unfortunate recent passing of Bill Pell,
who was for a time Section Head for Mathematical Sciences at the NSF.

Bill played a major role in making known, within the Foundation, the
unique needs of the mathematical sciences, and the mathematical
scientists as well.

Those of us who knew and worked with him will miss his kindness,
integrity, intellectual breadth and good humor.

Algebra in Statistics given by Ingram Olkin, George P. H.
Styan and Douglas Bates. There have now been scheduled over
200 talks, which includes 8 invited talks, 54 talks in
minisymposia, and about 140 contributed talks. It should be a
super meeting. A preliminary program for the conference can
be obtained by writing to SIAM at 1405 Architects Building,
117 South 17th Street, Philadelphia, PA 19103 USA. The final
program will be available at the conference.

On May 19-21, 1988 right before the conference, the
Mathematics Department of the University of Wisconsin will be
celebrating the 25th anniversary of the opening of Van Vleck
Hall which houses the Mathematics Department. On Saturday

entitled "Matrix and Combinatorial Theory-25 years at Van
Vleck" is being organized by Richard A. Brualdi and Hans
Schneider. They have invited all their former students and
colleagues of matrix and combinatorial theory to participate
and speak. However everyone is invited to attend the
miniconference. Those atttending the SIAM conference might
wish to take advantage of this opportunity while at the same
time taking advantage of reduced airfares for staying over a
Saturday night. For more information contact Richard A.

Subject: Argonne Parallel Programming Class

Argonne National Laboratory has set up an Advanced Computing
Research Facility (ACRF) for the study of parallel computing. It
currently features an 8-processor Alliant FX/8, a 20-processor
Encore Multimax, a 24-processor Sequent Balance 21000, a 32-processor
Intel iPSC hypercube, a 16-processor Intel iPSC-VX hypercube with
vector processors and a 1024-processor Active Memory Technology DAP.
Local projects utilizing the ACRF include investigations in parallel
logic programming and parallel linear algebra and the development of
portable parallel programming methodologies.

To encourage the use of the ACRF as a national facility, Argonne
is sponsoring classes to familiarize potential users with the ACRF
multiprocessors and parallel programming in general. The next class
will be held on April 27-29, 1988.

Topics to be covered include parallelizing compilers, the Monitor
and Schedule packages for portable parallel programming, hypercube
programming and programming the DAP. A portion of the third day will
be devoted to consideration of each attendee's particular project.
Fortran will be emphasized as the primary programming language. This
will be a hands-on class; at its completion participants will have
written and run programs on each machine, and should be familiar with
the ACRF environment.

Those interested in the classes should contact

Subject: Conference on Iterative Methods for Large Linear Systems


Second Announcement and Registration Form
CONFERENCE ON ITERATIVE METHODS FOR LARGE LINEAR SYSTEMS
October 19, 20 and 21, 1988
Celebrating the 65th birthday of David M. Young, Jr.

OBJECTIVE: This conference will be dedicated to providing an overview of the
state of the art in the use of iterative methods for solving sparse linear
systems with an eye to contributions of the past, present, and future. The
emphasis will be placed upon identifying current and future research
directions in the mainstream of modern scientific computing. Recently, the
use of iterative methods for solving linear systems has experienced a
resurgence of activity as scientists attack extremely complicated three
dimensional problems using vector and parallel supercomputers. Many
research advances in the development of iterative methods for high-speed
computers over the past forty years will be reviewed as well as focusing on
current research.

17.00 CONCLUSION


CONFERENCE PROCEEDINGS

The invited papers from the conference will be published as a special issue
of the International Journal of Supercomputer Applications.
In addition, the invited papers, a number of selected contributed papers,
and the six student scholarship papers will be published by MIT Press in the
form of a book that will follow the basic format of the Journal of
Supercomputer Applications. This book will serve as the proceedings of
the conference.

REGISTRATION FEES AND SCHEDULES

The registration fee covers the cost of all social activities including dinner
on Sunday evening. If an attendee does not wish to participate in an evening
social event then the registration fee covers the cost of dinner in the SAS
hotel. In addition each participant will receive a copy of the conference
proceedings.

The registration fee before April 29, 1988 is NOK 2,200 or the equivalent
in US Dollars or Pounds Sterling.

After April 29, 1988 the registration fee is: NOK 3,500 or the equivalent
in US Dollars or Pounds Sterling. The registration fee will be forfeited for
cancellations received after April 29, 1988.

PLEASE REGISTER AS SOON AS POSSIBLE BECAUSE THE NUMBER OF PARTICIPANTS MUST
BE LIMITED TO 450 PEOPLE.

Payment of fees MUST be received before May 27, 1988.

COMPANIONS PROGRAMME:

The social activities in the agenda are available to companions of conference
participants at the following subsidized rates, Monday evening: total
cost NOK 150, Tuesday evening: Banquet NOK 300, Organ Concert and trip
to Floeyfjellet no charge, Thursday evening: no charge. The lively
and exciting town of Tromsoe also offers a host of other activities that can
be arranged upon request.

TRAVEL:

The conference will be held at the SAS Royal Hotel in the city of Tromsoe,
Norway.

It has not been possible to obtain from Scandinavian airlines a guaranteed
and convenient charter flight to Tromsoe. Moreover, it seems likely that
attendees can obtain reasonable air fares if they book the complete
journey in their home country. Our enquiries show that travel agents should
have no difficulty in arranging regular scheduled flights to and from
Tromsoe.

Subject: Domain Decomposition Workshop


WORKSHOP on DOMAIN DECOMPOSITION ALGORITHMS.

Aug. 1. to Aug. 26.

UNIVERSITY of BERGEN, NORWAY


Following the initial workshop on domain decomposition
methods at Cornell University in 1986, the international
meeting in Paris Jan. 1987, and the international
meeting in Los Angeles 1988, leading researchers in this
field are invited to Bergen, NORWAY in August 1988.

Scientists with an active interest in this field are
invited to participate. Both short and long term visits
during the period is possible. There will be several
lectures, but the emphasis will be on informal exchange
of ideas and knowledge and possible joint projects among
participants.

Unfortunately, financial support will be extremely
limited.
