6-7 March 2023
Colleagues from Dioscuri Centre in Topological Data Analysis Instytut Matematyczny PAN (Polish Academy of Sciences, PAS), prof Pawel Dlotko, Niklas Hellmer visited us to strengthen the collaboration related to topological data analysis for damage detection.
We are excited to write paper together… more soon!
