Applied Electronics Conference
On September 25 to 27, UTN Bahía Blanca will host the uEA2013 conference. The event is an excellent place to meet students, academia, and industry related to electronics in Argentina. I hope to see you there!

#4 OpenCL headers [3]
There is a problem with OpenCL headers in Debian (it may be solved soon). Just downgrade the headers:
cd /usr/include/CL/
mkdir 1.2
mv cl.hpp ./1.2/
mv *.h ./1.2/
wget http://www.khronos.org/registry/cl/api/1.1/cl.hpp
wget http://www.khronos.org/registry/cl/api/1.1/opencl.h
wget http://www.khronos.org/registry/cl/api/1.1/cl_platform.h
wget http://www.khronos.org/registry/cl/api/1.1/cl.h
wget http://www.khronos.org/registry/cl/api/1.1/cl_ext.h
wget http://www.khronos.org/registry/cl/api/1.1/cl_d3d10.h

Our Work Presented at Shanghai!
Our work was presented at Edu-Par 12. It was part of the 26th IEEE International Parallel & Distributed Processing Symposium (IPDPS) located at Shanghai, China.
NSF/IEEE Award!
National Science Foundation (NSF) and the Technical Committee on Parallel Processing (TCPP) awarded me for a proposal about teaching parallel processing to undergrad students. The initiative is supported by the rest of the professors at UTN. You can see the complete list of the awarded initiaves here. Our material is here.

The Edges of Big Buck Bunny
Here you can see a sample of the work we are doing on video processing. In this case we are using an edge-detection filter. The original material is available at www.bigbuckbunny.org
