The Arctic Quasiperiodic Workshop
Workshoppen organiseras årligen av Luleå tekniska universitet, University of Utah, CNRS, Imperial College London och FOI. Syftet med workshopen är träffas för att diskutera och utbyta erfarenheter inom matematisk modellering inom kontinuum mekanik, där området eller materialet har en kvasiperiodisk mikrostruktur.
