Subject: Interactive Numerical Examples in ETNA

Many papers in computational mathematics contain numerical
examples that illustrate the theory discussed, or the virtues
or shortcomings of numerical methods. The examples, in general,
depend on certain parameters, whose values are chosen by the
author of the paper. A reader may be interested in studying
the examples for other parameter values, but typically this is
not straightforward. Computer programs may have to be written
or requested from the author of the paper.

The Electronic Transactions on Numerical Analysis (ETNA) makes
it possible to publish interactive examples that allow readers
to vary parameter values. Presently, two papers

J. Baglama, D. Calvetti and L. Reichel, Fast Leja points,
ETNA 7 (1998), pp. 124-140,

R. S. Varga and A. Krautstengl, On Gersgorin-type problems
and ovals of Cassini, ETNA 8 (1999), pp. 15-20,

illustrate this feature. Click on the ``interactive supplement''
for these papers for a demonstration.

Authors of papers accepted for publication in ETNA are encouraged
to supply interactive examples. The ETNA staff will assist with
the design and Java programming of the examples.

ETNA is available at

and at mirror sites. In addition volumes 1-10 of ETNA are available
on a new CDROM. The ETNA CDROM contains papers published in ETNA
1993-2000, interactive examples, a search engine and web browsers.
A limited number of CDROMs are available for $10 each. Please send
e-mail to if you would like your own portable copy
of ETNA on a CDROM.

Subject: Five New Codes for Stiff ODEs and DAEs

This is to announce some new codes and modifications of existing codes
for the solution of stiff initial value problems and differential algebraic
equations of index less than 4. All of these codes are based on the well
known approach defined by Modified Extended Backward Differentiation Formulae.
The codes are MEBDFDAE.f which is already in existence and has been
slightly modified. This solves linearly implicit DAEs of the form
My'=f(x,y). In particular it solves stiff ODEs when M=I.
In addition we have a code MEBDFV.f which solves
Also there is a code MEBDFI.f which solves general problems of the form
In addition there are two sparse solvers.
These are MEBDFSO.f which solves sparse systems of intial value ODEs
and MEBDFSD.f which solves sparse systems of DAEs.
These last two codes have particular applications
in the method of lines solution of time dependent partial differential
equations. Extensive results comparing these new codes with a whole variety
of existing codes together with double precision FORTRAN versions of all
the new codes are on the Imperial College web page. This can be
accessed at

of numerically computing or even representing all scales of action
is either very expensive or completely intractable. The Yosemite

lectures from leading specialists, a small number of tutorial
lectures, and contributed talks chosen from abstract submission.

expected to learn this within three years after appointment. The university
also requires that the applicant has a formal pedagogical education. Those
who have not have to take a pedagogical course during the first year.

An applicant who is offered a position as a senior lecturer will be
promoted to full professor if she or he asks for that and is found to be
competent after an evaluation procedure.

Criteria for ranking of candidates
The main criteria are scientific and pedagogical skills, with equal
emphasis on both.

When evaluating the scientific skill merits in computational methods for
large-scale problems and implementation on parallel computers are

Administrative skills and ability to cooperate with other persons will be
taken into account as well as ability to inform about research and

Recruitment objective
