Subject: MATLAB Package for Bifurcation Analysis of DDEs

Dear NA-reader,

We would like to announce the availability of DDE-BIFTOOL v. 2.00.
DDE-BIFTOOL is a Matlab package for the bifurcation analysis of
delay differential equations. It supports continuation and stability
analysis of steady states and periodic orbits.

The second version now also supports the computation of connecting
orbits (both homoclinic and heteroclinic solutions) and the analysis
of state-dependent delay equations, where the delay is a function of
the state.

More information about how to obtain the package, and an extended
manual, can be found on

With kind regards,

Koen Engelborghs, Tatyana Luzyanina, Giovanni Samaey

Subject: South American Congress on Computational Mechanics

The Argentinean Association for Computational Mechanics (AMCA)
and the Brazilian Association for Computational Mechanics (ABMEC)
announce the

MECOM 2002
First South American Congress on Computational Mechanics,

together with the
Terceiro Congresso Brasileiro de Mec=E2nica Computacional

and the
S=E9ptimo Congreso Argentino de Mec=E1nica Computacional,

which will be held in the cities of Santa Fe and Paran=E1, Argentina,

The Argentinean Association for Computational Mechanics (AMCA) was
created during the first MECOM Congress, which took place in 1985 in
Santa Fe-Paran=E1. Repeating the success of this first MECOM, subsequent
congresses were held in C=F3rdoba (1988), Santa Fe-Paran=E1 (1991),
Tucum=E1n (1996) and Mendoza (1999).

On the other hand, the Brazilian Association for Computational
Mechanics (ABMEC) was created in 1999. The first ABMEC Congress
was held in Rio de Janeiro in 2000, and the second one in Campinas,
in 2001.

Both Associations decided to share the organization of MECOM'2002 as
the First South American Congress on Computational Mechanics, which
will include the Terceiro Congresso Brasileiro de Mecanica Computacional
and the S=E9ptimo Congreso Argentino de Mecanica Computacional.
They also agreed on appointing the International Center for Computational
Methods in Engineering (CIMEC) as local organizer of the Congress.

Drummond Rennie, and Donna Stroup

This symposium is designed to address current issues in meta-analysis.
There will be reports on four topics: meta-analysis for policy decisions,
publication bias, heterogeneity models, and equating of medical outcome
measures. In addition, there will be other topics related to the
methodology of meta-analysis or systematic reviews. Saturday afternoon
will be devoted to a special session on reporting of medical data in the
media. This will be a panel discussion with journalists and
epidemiologists and statisticians.
