Introduction
Hilbert-Huang Transform (HHT) is a novel method developed by Prof Huang et al to perform nonstationary signal processing [1].
Huang et al applied HHT to the earthquake record from station TCU129, at Chi-Chi, Taiwan, collected during the 21 September 1999 earthquake [2].
Yang et al applied HHT to a benchmark problem established by the ASCE Task Group on Structural Health Monitoring [4].
It is obvious that under the effect of the El Centro wave, cracking or yielding of the structure concentrates in just 1~2 seconds.

The electroluminescence (EL) spectrum was recorded by Cary 5000 UV-Vis-NIR spectrometer.
(b) Normalized absorption and PL spectra of 2,7-di(9-carbazolyl)-9-(2-ethylhexyl)carbazole, and EL spectrum of the obtained OLED structure.
Electrical parameters of the obtained ZnO, ZnO:Al and ZnMgO:Al films.
The electroluminescence (EL) spectrum of the OLED structure exhibits the UV and violet electroluminescence.
The difference in PL and EL spectra can be explained by increasing of interactions of intermolecular excited state in the organic film under the electrical excitation.
