Subject: Professor Jean Laborde

I regret that I have to tell you that my father, Professor Jean Laborde,
passed away on October 5, 1997 at the age of 86. Together with Professor
Kuntzmann and Professor Gastinel at the University of Grenoble, he was
one of the pionneers of numerical analysis in France. He designed the
first computed numerical tables. They were published in 1961 and served
as a reference in the next thirty years for high school and university
students until the pocket calculator became common. They were known and
used in many places, including the Pentagone...

Subject: Langmuir film model

I am modeling the energy lost to the fill gas in incandescent light
bulbs. Currently I am using the Langmuir film model to calculate this.
This method works well when the ratio of the Langmuir film diameter to
the inside bulb diameter is less than 0.5. Is there another method that
might work better? Has the Langmuir film model been modified by anyone?
Currently, the calculation takes less than 1 second on my PC - and I
need it to be this quick. For this reason I do not what to do use any
of the CFD codes commercially available. Any help would be appreciated.

Subject: PseudoPack v2.2 beta

Hello, this message announces the PseudoPack v2.2 beta.

PseudoPack is a software library for numerical differentiation by
pseudospectral methods.

It is being developed at Brown University by Prof. Wai Sun Don and
Dr. Alex Solomonoff.

Its aims are to provide minimum roundoff error and good efficiency on
several computational platforms. They are SGI, Sun, IBM R6000 and Cray.

The software package is written in Fortran 77 with the C preprocessor. We
have used a few Fortran 90 extensions, namely long function and variable
names, and use of the enddo keyword.

It is freely available, at least to all non-commercial users.

If you have already downloaded the previous version before,
you know where and how to find the files.

Thanks for your time.

You can read the description from our Web page

Subject: Announcement of DAISY

DAISY: A Database for Identification of Systems

DAISY is an Internet application, mainly consisting of a database
of datasets used in system identification or time series analysis.
The system can be used in two directions: you can download datasets
from the database (e.g. to use them to compare or test
identification algorithms), and you can upload datasets to the
database (to make it possible for other people to use your datasets
to verify their algorithms, or to reproduce or enhance your
results). The datasets in the database are subject to a mild
review, so that we can guarantee a certain level of quality.

DAISY is an answer to a real challenge in research in system
identification and signal processing, namely to ensure the
reproducibility of results, based on real data. Often datasets are
used to illustrate algorithms in publications, but almost never
these datasets are public, so nobody is able to verify the results
stated. Using DAISY, this problem is history: if you need to
verify your algorithm with a real-world example, you can use
datasets from DAISY, or you can submit the dataset you used to
DAISY. This way everybody can (try to) reproduce your results.
Other benefits of DAISY include increased collaboration between
researchers, the gradual evolution of certain datasets into
benchmarks, and the publication of comparisons between different
methods or algorithms.

DAISY is a website consisting of a page with the datasets (sorted
by category), a page where you can submit datasets, and pages with
relevant links, all publications and talks about DAISY, a
bibliography and software overview, some hitting statistics, and
last but not least the acknowledgments to our sponsors.

DAISY is being developed and maintained at the department of Electrical
Engineering of the K.U.Leuven, in the research group SISTA, under the
responsibility of Bart De Moor.

Subject: Expokit - Software for Matrix Exponentials

Expokit is a set of user-friendly routines (in FORTRAN 77 and MATLAB)
aimed at computing matrix exponentials. More precisely, it computes
either a small matrix exponential in full, the action of a large
sparse matrix exponential on an operand vector, or the solution of a
system of linear ODEs with constant inhomogeneity. The backbone of
the sparse routines consists of Krylov subspace projection methods
(Arnoldi and Lanczos processes) and that is why the toolkit is capable
of coping with sparse matrices of very large dimension. The software
handles real and complex matrices and provides tailored routines for
symmetric and Hermitian matrices. When dealing with Markov chains,
the computation of the matrix exponential is subject to probabilistic
constraints. In addition to addressing general matrix exponentials,
a distinct attention is assigned to the computation of transient
states of Markov chains. Expokit is the first comprehensive package
specifically design for matrix exponentials from the outset.


The work resulting from Expokit has been accepted for publication
in ACM-TOMS. We are considering submitting the code itself to
ACM-CALGO. In order to strenghten the robustness and reliability
of the software, we will appreciate comments and bugs that users
might have.
