Horizon Workshop 2006a
HORIZON workshop 10 and 11 april 2006
This meeting is dedicated to the follow-up of the Horizon project tasks. The scientists involved in the project will have the opportunity to explain to the community the point they have reached in each of the subsections. Particular emphasize will be given to demostrate the development on each of the geographical nodes where Horizon mini-grid computers have been installed.
Please register below as soon as possible (below program).
