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).

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

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.

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.

The third SIAM Conference on Applied Linear Algebra will take

place in Madison, Wisconsin on May 23-26, 1988. It will be

preceded on Sunday, May 22,1988 by a short course on Linear

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

afternoon, May 21, of the celebration a miniconference

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.

Brualdi(brualdi@vanvleck.math.edu) or Hans

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

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.

For example, on Sunday June 5, 1988 the following flights are available:

NEW YORK - OSLO

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.

Professor Petter Bjorstad
