Research sponsored by INSEAN and NSF


Roma Üniversitesi “La Sapienza” ile birlikte yürütülen bu araştırma programı, karmaşık bir mekanik sistemde titreşimli enerji akışının geri dönüşümsüzlüğünü incelemektedir. Spesifik olarak, bu araştırma, bir yapının klasik sönümlenme özellikleri göstermeyen karmaşık bir rezonatör ile birleştirilerek bir yapının sönümlemesini artırabilen koşulları araştırır.
