In general, carbon materials with high specific surface area (SSA), well-balanced pore size distributions, and appropriate content of heteroatom functionalities are essential to enhance the performance of electric double layer capacitors (EDLCs) for capacitive energy storage. In this study, a low-cost biological waste-stiff silkworm was first used as precursor for the synthesis of well-developed microporous...
The 3D discrete fluorescence spectra with 12 excitation wavelengths (400, 430, 450, 460, 470, 490, 500, 510, 525, 550, 570, 590nm) were determined by fluorescence spectrophotometer for 20 phytoplankton species. Then, the wavelet (Coif2), fourth-derivative and non-negative least squares were applied to establish the fluorescence differentiation method which could differentiate phytoplankton populations...
In this study, a fluorescence spectra discrimination technique for red tide algae by Wavelet packet transform was developed. The fluorescence excitation-emission spectra were determined by fluorescence spectrophotometer for 24 red tide algae. Then the coefficient vectors (candidate feature spectra) were obtained by decomposition of Coiflets-2 wavelet packet. Bayesian discrimination was applied to...
