The DC team was present at the joint conference CIB W78 - LDAC 2021, where we presented our department's work and current research results. The event took place from the 11th to the 15th of October and started in Belval, a site hosting the steel industry of Luxembourg and nowadays undergoing a conversion towards research and culture, and moved in the middle of the week to the cultural meeting point of Neumünster Abbey.
