AB  - Bu çalışmadazaman-frekans ortamında uygulanan hasar tanılama tekniklerinde gözlenen sonaraştırmalara bakılarak yeni hasar tanılama algoritmaları incelenmiştir.Özellikle yapı sağlığı çalışmalarında ivme, hız ve deplasman gibi kinematik parametrelerive bunların türevleri üzerinden örneğin hız bilgisinin enerji tabanlı kinetikbir parametre ile ifade edilerek etkin hasar tespitleri yapılabildiği bilinmektedir.Analitik modellerden elde edilen sitasyoner ve ergodic yapıda olmayan kinematikölçümlere dalgacık dönüşümleri uygulanarak hasar alan ve doğrusal olmayanözellik gösteren yapısal elemanlar tespit edilmiştir. Sürekli dalgacık dönüşümüve dalgacık paket dönüşümü uygulanan örneklerde bu metotların hasar tespitindeetkili bir yöntem olarak kullanılabileceği sonucuna ulaşılmıştır.
