Total soluble solids (TSS) and titratable acidity (TA) are essential quality properties for
postharvest commercialisation of grapes. This study aimed to estimate the TSS and TA in …

The rich flavors and antioxidant properties within Maofeng tea are mainly attributable to
numerous secondary metabolites and thus may be related to quality. Motivated by this …

We have developed a novel 3D asynchronous correlation method (3D-ACM) designed for
the classification and identification of Chinese handmade paper samples using Raman …

Background Spectral intensity drift is a frequent issue in analytical processes, especially in
long time excitation scanning for large size metal materials, which can significantly …

For spectrometers, baseline drift seriously affects the measurement and quantitative analysis
of spectral data. Deep learning has recently emerged as a powerful method for baseline …

The paper introduces two new methods, namely the cross correlation method (CCM) and
two-dimensional correlation method (TDCM), for preprocessing Raman spectroscopy data …

摘要在激光打靶数字延时信号处理中, 传统滤波算法往往难以有效滤除噪声干扰, 导致信号失真.
