Hello!

Does anybody know of a public domain (or even commercial) software

doing FFT, convolutions, etc. tuned to have a good performance on

i486 (80486) microprocessor?

Any help will be appreciated.

PhD Abstracts in Numerical Mathematics

The SIGNUM Newsletter, a quarterly publication of the ACM Special

Interest Group on Numerical Mathematics, is interested in publishing

one paragraph abstracts of recent Ph.D. theses in numerical mathematics.

A recent Ph.D. thesis should have been completed within the last year.

If you (or your student) qualifies, then you can get good publicity,

and help educate the numerical mathematics community, by submitting

a one paragraph abstract, along with the name of the student, associated

institution/department, advisor's name, and thesis approval date, to:

Thomas F. Coleman, SIGNUM Board Member

**Subject: Submatrices with the Best-Bounded Inverse**

SUBMATRICES WITH THE BEST-BOUNDED INVERSE

Lately I came across the next "pure linear algebra" problem.

Suppose we have r columns of an orthogonal matrix

of order n, that is, U is n-by-r and such that U^tr * U = I,

and we want to find an r-by-r submatrix in U which has

the best-bounded inverse.

In other words, let S denote the set of all U as above,

and M(U) the subset of all U's r-by-r submatrices. Let

t(r,n) = 1 / min_{U belongs to S} max_{P belongs to M(U)} s(P)

where s(P) means the minimum singular value of P.

What is a good upper bound for t(r,n)?

I can easily prove that t(r,n) is no greater than the square root

of C^r_n ( the number of r-combinations among n things ).

But I quess that there should be much better estimate like

t(r,n) .LE. n^{1/2}. (*)

We have had some numerical experiments, and saw that (*) was never

violated. Interesting, that we noticed that

t(2,n) .GT. (n-1)^{1/2}.

So a "nice" question arose of whether (*) holds or not.

Even the case r = 2 is not clear.

I will appreciate any advice.

Sincerely,

Evgenij Tyrtyshnikov (tee@adonis.ias.msk.su )

**Subject: FTP Site at Katholieke Universiteit Leuven**

Now available by anonymous ftp:

Internal reports and (p)reprints of the research group SISTA

(Signals, Identification, System Theory and Automation) of the

division ESAT (Electronics, Systems, Automation, Technology) of the

department of Electrical Engineering of the

Katholieke Universiteit Leuven, Leuven (=Louvain), Belgium.

SISTA is the group of Prof. Joos Vandewalle and Prof. Bart De Moor,

and contains some 25 researchers working on topics in numerical linear

algebra, system identification, control system design, neural nets and

nonlinear systems.

1. Create an FTP connection from wherever you are to machine

"gate.esat.kuleuven.ac.be". The internet address of this machine is

134.58.56.20 , for those who need it.

2. Log in as user "anonymous" with your own e-mail address as password.

This is not because we want to monitor you, but because we like to know

when somebody is interested in our reports.

3. Change remote directory to "/pub/SISTA/<author>/reports", i.e. type:

cd /pub/SISTA/<author>/reports

where <author> is the name of the guy whose paper you are interested in.

Of course one can get a listing of the authors by typing:

ls /pub/SISTA

4. Get the report or (p)reprint you are interested in, typing:

get <report>

Here <report> is the name of the report, typically in the format

*.ps.Z (compressed Postscript). One can use the unix command 'uncompress'

to uncompress them.

A listing of the reports of <author> may be obtained by typing:

ls /pub/SISTA/<author>/reports

This directory also contains a file ABSTRACTS, where you find abstracts

and some other info on each report

Note:

The exact FTP commands you should use may depend on your local FTP program.

Remember to use the binary transfer mode for compressed files.

All of this is also contained in more detail in the file /pub/SISTA/README

Post-Doctoral Research Position

The Department of Electrical and Computer Engineering at the Air Force Institute

of Technology(AFIT) is inviting applications for a post-doctoral research

position. The appointment is available in the fall of 1993. The successful

candidate will participate in the development of extensions to the theory of

variable-length signal processing in the context of Fourier and wavelet analyses

to achieve more powerful and flexible options for discrimination, detection,

speaker identification, anti-jamming, etc. Computational facilities are of the

highest caliber and are continually being expanded.

Minimum requirements are (1) U.S. citizenship; (2) a Ph.D. in electrical

engineering, mathematics, or computer science; and (3) knowledge of Fourier

analysis, wavelet analysis, and signal processing. Salary is commensurate

with qualifications.

AFIT is located in southwestern Ohio, just outside Dayton, offering the

advantages of affordable housing, good schools, and access to the Air Force

Laboratories at Wright-Patterson Air Force Base.

Applicants should: (1) send a curriculum vitae, including a list of

publications; (2) send reprints of best publications; and (3) ask three

people to send letters of recommendation to: Dr. Bruce W. Suter, Dept. of

Electrical and Computer Engineering, Air Force Institute of Technology,

AFIT/ENG, 2950 P Street, Wright-Patterson AFB, OH 45433-7765.

AFIT is an equal opportunity, affirmative action employer.

Numerical Analysis Postdoctoral Position at Manchester

The Science and Engineering Research Council are funding a three

year Research Assistantship for a project titled

``Parallel Eigenvalue Computations''.

The successful applicant will join the Numerical Analysis group at the

University of Manchester, and will work closely with grant holder

N. J. Higham.

The aim of the project is to develop parallel algorithms

for the nonsymmetric eigenvalue problem.

Excellent computing facilities are available, including a MasPar

MP-110 in the Department of Mathematics, and a Kendall Square KSR1 in

the Centre for Novel Computing.

The appointment will be made at the RA 1A level, with a current

starting salary of 14,962 pounds sterling per annum.

The start date is no more than six months after 1st June 1993.

Applicants should hold, or expect to complete before the start date,

a PhD, and should have a strong background in numerical analysis

and linear algebra, preferably with parallel computing experience.

Applications and requests for further information should be sent

as soon as possible to
