**Subject: Summing a Trigonometric Series**

I am interested in efficiently evaluating an infinite sum whose terms are

trig(q*n)/n**(0.5+m) where "trig" is either a sine or cosine, q is a positive

irrational number which ranges from 0 to approximately 10 or 20, m is a small

nonnegative integer, and the series includes terms from n=1 to n=infinity. I

am especially interested in the case m=0, a series which is NOT absolutely

convergent. I am intriqued by an idea suggested in a 1949 text by G. H.

Hardy entitled "Divergent Series", in which it is suggested that one evaluate

the m=0 series by expanding the 1/n**0.5 factor into an infinite series of

binomial coefficients ("N choose n"), where "N" equals n-0.5-j and j ranges

from 0 to infinity. (Because not both of the arguments of the binomial

coefficient are integers, the binomial coefficient equals a simple ratio of

gamma functions instead of factorials.) Next, Hardy suggests inverting the

order of the summation; the series (over j) involving the binomial coefficients

can be performed analytically, and PERHAPS the remaining sum (over n) converges

quickly. Unfortunately, Hardy does not provide the expansion coefficients for

the expansion of 1/n**0.5 into a series of binomial coefficients, and I am

unaware of any special type of "orthogonality" relationship that the binomial

coefficients satisfy (which would enable me to uncover the expansion

coefficients). Does anyone know what these expansion coefficients are, or does

anyone know of an alternative efficient way of summing this type of series?

**Subject: New Book, Gabor Analysis and Algorithms**

Announcement of New Book

GABOR ANALYSIS AND ALGORITHMS

Theory and Applications

Edited by H.G. Feichtinger and T. Strohmer

ISBN 0-8176-3959-4 * 1997 * $64.95 * Hardcover * 500 pages *

available from Birkaeuser - Boston, http://www.birkhauser.com

The field's leading international experts have come together to

give a detailed survey of the theory of Gabor analysis, a method

of time-frequency analysis and its applications in signal and

image processing. This book is a collection of surveys

thematically organized, showing the connections and interactions

between theory, numerical algorithms, and applications. It gives

an overview of the different branches of Gabor analysis, and

contains many original results which are published for the first

time.

The book provides an introduction to mathematicians and engineers

who want to learn about the different approaches and aspects of

Gabor analysis or want to apply Gabor-based techniques to tasks in

signal and image processing. It is an especially useful reference

for research specialists in harmonic analysis, applied

mathematics, numerical analysis, engineering, signal and image

processing, optics, and pattern recognition.

**Subject: SNOPT/AMPL Available from NEOS Server**

The NEOS Server is now offering SNOPT for the solution of nonlinearly

constrained optimization problems in AMPL format.

SNOPT is suitable for large nonlinearly constrained problems with a

modest number of degrees of freedom. SNOPT was developed by

Philip E. Gill, Walter Murray, and Michael Saunders.

Installation of the SNOPT solver would not have been possible

without the help, guidance, and advice of Bob Fourer, David Gay,

and Philip Gill.

You can try out SNOPT by visiting the NEOS Server at

http://www.mcs.anl.gov/otc/Server

You can also use email; instructions are obtained by the message

**Subject: Special Issue of Reliable Computing**

CALL FOR PAPERS

Reliable Computing (Kluwer Acad. Publ.)

Special Issue on Applications to Control, Signals, and Systems

Much of modern engineering theory addresses problems involving uncertainty.

E.g., in control theory, a typical scenario begins with a system to be

controlled and a mathematical model of this system which depends on

uncertain quantities. This model thus involves various physical parameters

whose values may be specified only within given bounds. Besides these data

uncertainties, the designer is faced with another difficulty: Many problems

require a yes/no answer, e.g., stable/unstable. Even when an algorithm

designed to solve such a problem can find the correct result using real

arithmetic, it may fail to do so due to rounding errors when implemented on

a computer using floating point arithmetic. Interval methods appear as an

appropriate tool to cope with data uncertainties as well as with rounding

errors. However, designers are often confronted with a nonlinear uncertainty

structure which makes the problem considerably more difficult. E.g., after

massaging the study of the stability of some uncertain system into a

polynomial problem with coefficients depending on uncertain parameters,

these parameters generally enter into more than one coefficient of the

polynomial, and in many cases, these coefficients depend nonlinearly on the

uncertain parameters. In addition to the traditional domain of affine and

multiaffine uncertainty structure, recent advances have opened up potential new

application areas for reliable methods in communications, control, signal

processing, and related fields. The application-oriented special issue of

Reliable Computing is intended to provide a forum for the presentation of

advances in using reliable methods in these areas.

Faculty Positions

Computational Science and Engineering

University of California, Santa Barbara

The College of Engineering at the University of California, Santa

Barbara is in the process of developing a multidisciplinary

college-wide program in Computational Science and Engineering

(CSE). An objective of the CSE program is to build strengths in the

core areas of numerical methods, algorithms and software tools for

scientific computation, high performance computing and communications,

and scientific visualization, as well as to establish collaborative

linkages in the applied areas of CSE such as computational fluid

dynamics, quantum computation, nanoelectronics, control systems,

computational materials, etc.

Applications are invited from outstanding candidates at all

levels. The College of Engineering is recruiting for a senior-level

position in the CSE program. In addition, an assistant professor

position in Computer Science is targeted at the core areas of CSE, and

a senior-level position Mechanical and Environmental Engineering is

directed at the applied area of computational fluid

dynamics. Multidepartmental appointments within the College of

Engineering are possible, in both the core and applied areas. Senior

candidates should have established an international reputation in an

area within the broad framework of the program, and a track record of

interdisciplinary collaboration. Junior candidates should have

outstanding research potential.

Please send a complete application consisting of a curriculum vita and

the names and addresses of at least four professional references to:

Search Committee in Computational Science and Engineering, Dean's

Office, College of Engineering, Engineering I Bldg., Room 1016,

University of California, Santa Barbara, CA 93106. Applications and

nominations will be received until the position is filled. UCSB is an

equal opportunity, affirmative action employer.

**Subject: Visiting Positions at Arizona State University**

The Department of Mathematics at Arizona State University expects to have

one or possibly two visiting positions for the Spring semester, 1998.

The visitor will have to teach 2 courses during the spring, most likely

including calculus. Expected salary is in the range 15-20K, dependent on

funding sources, and on current pending personnel decisions. We will

provide office space, computer facilities, and some relocation expenses

for travel within the US.

We recommend that applicants arrange for three external letters of

recommendation to be sent directly to the R. Renaut, Chair, Department of

Mathematics, Arizona State University, Tempe, AZ 85287-1804, email

renaut@asu.edu, fax 602-965-8119. Letters of application should be sent

as quickly as possible to R. Renaut, indicating that the applicant is

applying for a visiting position for Spring 98. Applications must include

a full vita, and a statement of research interests and teaching experience

is desirable. We hope to identify an appropriate individual(s) during the

first week of December. AA/EOE.
