In this research, the modal parameters of a beam in free-free condition are extracted by performing different experiments in laboratory. For this purpose, two different techniques are employed. The first methodology is considered as a time domain method in Operational Modal Analysis. While the other one is frequency domain impact hammer test which is categorized as an Experimental Modal Analysi...

Two photo-luminescence bands characterized by their excitation in c-As2S3 shows a surprising similarity to those in a-AsZS3. In addition, a band in c-As2S3 can be interpreted as due to the recombination of localized excitons as well as a luminescence band in a-As2S3. The luminescence bands in a-As2S3 are discussed on the basis of the luminescence processes in c-As S 2 3' In a-As S it is suggest...

The invention of two-photon fluorescence light microscopy by Denk, Webb and co-workers (Denk et al., 1990) revolutionized three-dimensional (3D) in vivo imaging of cells and tissues. In 1931, the theoretical basis of twophoton excitation was established by Maria GöppertMayer, and this photophysical effect was verified experimentally by Kaiser and Garret in 1963. Two-photon excitation is a fluor...

Fluorescence correlation spectroscopy (FCS) could provide a more useful tool for intracellular studies and biological sample characterization if measurement times could be reduced. While an increase in laser power can enable an autocorrelation function (ACF) with adequate signal-to-noise to be acquired within a shorter measurement time, excitation saturation then leads to distortion of the ACF ...
