The GSOC programme for 2009 is now finished, and we have several exciting new features added to ASCEND. Of general interest will be
* improved DAE syntax, that to Dante,
* full support for the IPOPT optimisation solver, together with
... [More]
exact calculation of second derivatives, thanks to Mahesh,
* support for reading data from CSV and other tabular data formats, with cubic spline interpolation, thanks to José
Of a more experimental nature, we also have
* major improvements to the new canvas-based GUI, thanks to Arijit
* exciting new developments for real-time data processing with ASCEND, thanks to Dipak.
We hope to integrate all of these changes into the ASCEND repository trunk in the coming weeks.
Thanks to all our wonderful students, and for all your hard work!
Cheers

Student proposals for work with ASCEND as part of this year's Google Summer of
Code have been announced on the GSOC website:
http://socghop.appspot.com/org/home/google/gsoc2009/ascend
We would like to congratulate the five
... [More]
successful applicants, and to thank
everyone who submitted a proposal.
It was great to see so much interest in ASCEND from far and wide, and to see
so many (over 60) high-quality applicants. There were many fine proposals for
interesting projects which we would have very much liked to pursue but which
could not be accepted due to the limits on the number of 'slots' available to
us.
For those who weren't successful, please consider staying involved in the ASCEND
project. You might find that you can simple make use of ASCEND during your
studies, or you might find that the opportunity arises to make some
contributions to ASCEND as part of your final-year or honours year projects.
Please keep us in mind! Contributions are always welcome.
Thanks again, everyone! (0 comments) [Less]

Hi all
We're having some more hardware problems with our machine at CMU, so once again our Wiki and Subversion repository are offline. We are investigating the problem and hope to online again soon.
