Pengembangan teknik penentuan lokasi kerusakan dini elemen mesin berbasis penjalaran emisi akustik dalam material = Development of machine element incipient crack localization technique based on acoustic emission propagation in solid material
" Deteksi emisi akustik dilakukan untuk menjawab kebutuhan akan tanda-tanda kerusakan sedini mungkin pada komponen mesin. Emisi akustik sendiri merupakan pelepasan energi gelombang tegangan pada saat deformasi awal yang menjadi indikator kerusakan skala mikro komponen mesin, yang tidak dapat dideteksi dengan metode lain. Namun, perkembangan deteksi emisi akustik menjadi lamban karena sulitnya melakukan reka ulang proses penjalaran gelombang emisi akustik untuk dapat mengidentifikasi lokasi sumber kerusakan dini pada elemen mesin. Tujuan penelitian ini adalah mengembangkan teknik ... "

Denoising acoustic emission signal using wavelet transforms for determining the micro crack location inside of concrete
" Acoustic emission (AE) technique is developed to locate source of damage inside of concrete. However, the AE signal is interfered by much noise, which makes the determination of first time amplitude of AE signal is hard to be carried out. In fact, the determination of this parameter is a significant part for locating the source of damage in concrete. Therefore, one of the denoising methods called wavelet based denoising is proposed. In this case, some ... "

Electromagnetic material interrogation using conductive interfaces and acoustic wavefronts
" Electromagnetic theory offers fascination and challenge from both a physical and a mathematical perspective. This monograph contains the newest results on the use of electromagnetic probes to interrogate dielectric material structures for material properties and geometry. This volume systematically exploits interface phenomena, the electrodynamics of material responses, and time dependent interrogating signals in an integrated manner. The authors begin with basic electromagnetics, such as Maxwell's equations, and present modeling, theory, and computational results. The book's ... "
