Earlier this year I’ve successfully defended my Engineering degree thesis. The making of took me about two years and produced several papers that were published as book chapters or articles.

The thesis was entitled “Pattern recognition on Medical Images based on Intelligent Systems” (in Spanish) and makes an approach to mammography anomalies detection using back-propagation neural network algorithms and other image processing filters like Sobel operator. After comparing the proposed method with former ones I found out that I had achieved 89% of success rates compared to 60% obtained by previous work. I’m still not so happy with the result, I believe a 99% may be achieved very easily.

The produced papers where

• Calot, E. et al. 2009. Tumor Classification on Mammographies Based on BPNN and Sobel Filter. In Opportunities and Challenges for Next-Generation Applied Intelligence. Studies in Computational Intelligence Series, Volume 214. pp. 19-24. ISBN 978-3-540-92813-3 (in English).

In both cases I was unable to travel. In the first one was in Chilecito, Argentina, but I had a schedule issue due to the presentation of the repertory grid paper. The second one was in Tainan, Taiwan but another scheduling issues and the swine flu outbreak made the trip impossible.

During the past year I’ve been involved in the development of a web based HIS.

The result was a software called Bio which -even though it is still not in a mature stage- some modules have been released to production: Medical Schedule and Invoice Entry.

The Princed Project is the sum of many sub-projects related to Prince of Persia. Such software includes level editors, graphic and sound editors, resource extractors, and a new open source engine for the game. All the software in this website is Free Software, and is also available for several platforms.

I have started this project and found a lot of people who wanted to help. After several years a big nostalgic community had grown. I want to help all the people who gave a lot to this project and I’m very proud of it.

Together with the project coworkers, we’ve used our spare time to reverse engineering the original game understanding all the format and produced a big specification of it. I’ve created a program to decompress the game graphic, sound and maps and convert them into standard format helping the people to edit the game. Thanks to this project and RoomShaker, a level editor created by Brendon James, there are more than 40 new mods of the game.

You can find resources on the project homepage: PR is the decompressor to extract the files, PV3 is a level editor, CusPOP is a web-based game editor capable of creating new .exe files with the desired customization.

FIUBA’s Cartelera is a web Information System created to show class marks on-line. I’ve been involved it its creation and currently I’m its administrator. It is used by FIUBA, that is the Engineer School where I teach in.

I’ve have always been proud of the school I’ve got my bachelor degree, Colegio Nacional de Ushuaia. It is related to the Colegio Nacional de Buenos Aires, who proudly produced two Nobel Prize laureates and four presidents. It depends on the UBA, the university I attend and teach in two classes (where 5 nobel laureates had tought and 14 presidents got a degree).

I’ve been involved in the creation of an IT system to manage all the school administration from student attending records to mark calculations and publishing. I’ve also have maintained an advanced homepage and implemented IPv6 in their internal network.
