Subject: Change of Address for Tom Coleman and Yuying Li
Dear colleagues: Yuying and I have begun new careers at the University of
Waterloo starting July 1. Yuying is now a professor in the Computer Science
Department and I am the new dean of the Faculty of Mathematics (replacing
long-serving Alan George who has retired from this position but continues at
Waterloo as an associate provost (information systems)).
We are both very excited about our new roles!
Our new email addresses are: yuying@uwaterloo.ca tfcoleman@uwaterloo.ca

Subject: The Curvelab Toolbox at Curvelet.org
Curvelab is a new toolbox implementing the Curvelet transform, both in
Matlab and C++, and can be downloaded from http://www.curvelet.org
Curvelets are multiscale oriented basis elements that were introduced by
Candes and Donoho to address the problem of representation of edges in
geometrical images. Since then, they have found applications at least in
seismic imaging, astronomy, and the numerical analysis of wave equations.
The software Curvelab contains two distinct implementations of the 2D
Curvelet transform, namely via Wrapping and via USFFT. Both architectures
are introduced and explained in the report 'Fast Discrete Curvelet
Transforms', available online. The 3D transform is also present in
Curvelab, in three different versions: in-core, out-of-core and fully
MPI-based parallel. The 3D code is covered in a separate online report.
Several demo files illustrate the transforms at work on image processing
tasks such as denoising and partial reconstructions. Additional routines
are provided to help the user understand the geometry of the transform
(location, orientation and scale for each coefficient.) A user's guide
explains how to set up the toolbox step-by-step on your computer.
The webpage http://www.curvelet.org is also meant to serve as a repository
of papers related to curvelets as implemented in Curvelab. It contains a
list of links to applications of curvelets, and researchers in the field.
There is also a mailing list: sign up to stay up-to-date on future
software releases and other curvelet-related information.

Subject: "Many Digits" Friendly Competition 2005
THE "MANY DIGITS" FRIENDLY COMPETITION 2005
4 October 2005
Radboud University, Nijmegen, The Netherlands
Call For Participation
<http://www.cs.ru.nl/~milad/manydigits>
In the Institute for Computing and Information Sciences at Radboud
University Nijmegen we will organise a friendly competition/benchmark
session for investigating the state of the art in the various
implementations of exact real arithmetic. The event will be held on
October 4th 2005, in conjunction with the Small TYPES workshop on
Constructive analysis, types and exact real numbers
<http://www.cs.ru.nl/fnds/typesreal/>.
The event will be akin to those held in CCA00
<http://www.cs.swan.ac.uk/~csjens/pdf/resart.pdf> and CCA2002
<http://www.informatik.uni-trier.de/~mueller/cca2002/>. All the
interactive software packages capable of handling arbitrary precision
arithmetic on elementary functions are invited to
participate. Moreover all libraries for handling arbitrary precision
arithmetic in any programming language are welcome to participate
provided that the participant writes a suitable interface/program.
The participants can choose to attend the event at Nijmegen, or they
can choose to participate remotely via Internet.
Friendly Competition
The friendly competition consists of giving a solution to a set of
problems that are posed by the organisers shortly (few hours) before
the event. The problems cover the minimum abilities of a system
capable of handling the elementary real functions and are expected
to ask for a large (>=10,000) number of digits. An example of a
problem that might be in this set is to calculate the first 10,000
digits of sin(sin(1)).
A set of `practice problems' can be found on the website of the
competition
<http://www.cs.ru.nl/~milad/manydigits/sample_questions.php>.
The solutions consist of the input needed to generate the answers to
the problems plus the answers themselves. The competition criteria
will be the accuracy (correctness) of the solution and the time
needed for producing the solution. Apart from this, we will also
compare the other aspects of the solutions (such as memory usage and
readability and length of the input code) to give a better
comparison.
On the day of the competition the solutions will be executed by
participants on one specific machine at the event site, under either
Debian/GNU Linux or Windows XP.
A more detailed description of the setup and format of the
competition can be found on the website of the competition
<http://www.cs.ru.nl/~milad/manydigits/rules.php>.
The outcome of this friendly competition is expected to give a
comparison in performance of the systems that chose to participate
for the selected problems.
Remote Participation
In case of remote participation, the participants will receive the
set of problems by email. Then they will be given the opportunity to
log into our local machine and perform their solution.
Systems, Packages and Libraries
Those who wish to participate in the Friendly Competition are
expected to provide the software necessary for their solutions, so
it can be run on the machine used for the competition.
Schedule
* August 26th deadline for registering for the competition
* August 29th final list of registered participants on the web
* September 23rd timings of the practice problems for the
registered participants posted on the web
* October 4th competition
Registration
If you are interested in participating in the event we will be happy
to hear from you:
1.Team name, name and email of contact person(s) and the platform
your system needs to run (GNU Linux or Windows XP).
2.Whether you plan to come to the meeting or whether you would like
to participate remotely.
We would prefer that participants (especially those whose system
requires Windows) to send their intention to participate before
August 26th, 2005.
Please register by sending mail to <manydigits@cs.ru.nl>.
