At this point we have the necessary framework to combine all these concepts together into the wavelet energy absorption (WEA) method. At this point we have the necessary framework to combine all these ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...
