Excursion to SOLVAY



As part of the PSE group work, the group supervised by the DYN chair presented their results at our industrial partner SOLVAY in Paris. In the SOLVAY research and development center, the group discussed their work with the SOLVAY experts and gained an insight into polymer preparation and analysis. The topic of the group work was “Process Design of a Production Plant for Acrylamide/AMPS (2-Acrylamido-2-Methylpropanesulfonic acid) Copolymer”.

DYN at Skopje-Dortmund Workshop on Control and Optimization

Skopje DYN 

A DYN team composed of 14 current members and former colleague PhD. Goran Stojanovski participated at the Skopje-Dortmund Workshop on Control and Optimization, between 13-15 October 2015 in Skopje, Macedonia. The workshop was hosted by the Automation and System Engineering Group of the FEEIT Skopje and included, amongst others, talks on iterative optimizing control, priced based coordination, modelling of systems-of-systems, vision based control of UAVs and mathematical modelling applied in medicine (see list below). The technical aspect was reinforced by a visit at the steel mill MakSteel, where the engineers and researchers engaged in discussions about the current challenges in optimization of steel sheet production. The workshop ended on a cheerful note, with a visit to the old Bazaar in Skopje and a tour of this charismatic Balkanic city.
