The Jubilee Event dedicated to the 60th anniversary of the Institute for Informatics and Automation Problems of the National Academy of Sciences will take place on November 30, 2017, at 15:00 in the big hall of the institute.

The EU is pleased to support since 2015 the Eastern Partnership Connect project and its efforts to provide not only physical networks to interconnect Eastern Partnership (EaP) and other countries with high-speed broadband connections, but also its efforts to build online services for research and education, to extend its reach beyond supporting big science and research and to offer support also to the arts and humanities. Projects like this are of strategic importance to help bring EaP and European neighbours closer together
said the European Commission Directorate-General for Neighbourhood Policy and Enlargement Negotiations’ Neighbourhood East Director Lawrence Meredith.
