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.

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.

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.

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.
