Accurate and rapid spectrum fitting is very important for quantitatively analyzing laser-induced breakdown spectroscopy (LIBS). The Voigt function often used to fit LIBS spectral lines. We propose a new approximate formula. Based on the classic Lorentz–Gauss linear combination formula, summation term was added that contained specific convolution operation improve function’s calculation accuracy. This formula can be of with an overall accuracy 0.31% full width at half-maximum internal 0.25%...
Abstract Co‐free Li‐rich layered oxides (CFLLOs) with anionic redox activity are among the most promising cathode materials for high‐energy‐density and low‐cost lithium‐ion batteries (LIBs). However, irreversible oxygen release often causes severe structural deterioration, electrolyte decomposition, formation of unstable cathode‐electrolyte interface (CEI) film high impedance. Additionally, elimination cobalt elements further deteriorates reaction kinetics, leading to reduced capacity poor...
The laser-induced fluorescence (LIF) technique, which has been widely used for food testing, can be combined with various algorithms to classify and recognize different kinds of honey. This paper proposes the Kolmogorov–Smirnov test-Gaussian mixture model (KS-GMM) algorithm, is coupled LIF technique realize accurate classification recognition types pure experiments are designed carried out obtain a set spectrum data from honey syrup samples. proposed KS-GMM algorithm applied recognition,...
