Comparison of Methods for Estimating Mechanical Properties of Wood by NIR Spectroscopy by L. R. Schimleck, J. L. M. Matos, R. Trianoski, J. G. Prata

“…The calibrations obtained for density (R2 = 0.81, SECV = 38.5 kg/m3) and MOE (R2 = 0.81, SECV = 1124 GPa) using benchtop instrument spectra demonstrate that it is possible to obtain general calibrations for estimating the wood properties of a number of tropical, subtropical, and temperate pine species.…”

Determination of the Degree of Degradation of Frying Rapeseed Oil Using Fourier-Transform Infrared Spectroscopy Combined with Partial Least-Squares Regression by Jie Yu Chen, Han Zhang, Jinkui Ma, Tomohiro Tuchiya, Yelian Miao

“…The precise calibration model based on the second derivative FTIR spectra shows that the coefficients of determination for calibration (R2) and standard errors of cross validation (SECV) were 0.99 and 0.16 mg KOH/g and 0.98 and 1.17% for AV and TPC, respectively. …”
