Prediction of elemental components of ground bamboo using micro-NIR spectrometer [PDF]

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The combustion performance depended on heating value of as-received bamboo which involved elemental components (C, H, N, O, S). The experiment using Micro-NIR spectrometer to investigate of 80 ground bamboo samples and partial least squares regression (PLSR) with cross validation technique was used to develop the model.
