Determination of 27 chemical constituents in Chinese southwest tobacco by FT-NIR spectroscopy
TL;DR: In this paper, a near infrared (NIR) spectroscopy was applied to quantitative analyses of 27 chemical components in Chinese southwest tobacco including routine chemical components, aromatic constituents, inorganic nutrients and heavy metals.
Journal ArticleDOI
Rapid determination of major bioactive isoflavonoid compounds during the extraction process of kudzu (Pueraria lobata) by near-infrared transmission spectroscopy.
TL;DR: The results showed that the approach was very efficient and environmentally friendly for rapid determination of the four quality indices (QIs) in the kudzu extraction process.
Journal ArticleDOI
Detailed analysis of the online near-infrared spectra of pharmaceutical blend in a rotary tablet press feed frame.
TL;DR: It is concluded that the NIR probe in the feed frame can rapidly detect moderate changes in API concentration in the blend and be a good predictor of tablet potency at the same time point and proven that the univariate analysis is a viable option.
Journal ArticleDOI
Recent advances in the applications of vibrational spectroscopic imaging and mapping to pharmaceutical formulations
TL;DR: An overview of FTIR, NIR, terahertz spectroscopic imaging and Raman mapping will be presented to give a perspective of the current state-of-the-art of these techniques for studying pharmaceutical samples.
Journal ArticleDOI
Applications of near-infrared spectroscopy (NIRS) in biomass energy conversion processes: A review
TL;DR: In this paper, a fast and non-destructive method for energy conversion of biomass is proposed. But this method is not suitable for high variability, making its utilization challenging.

Nearest neighbor pattern classification
Thomas M. Cover,Peter E. Hart +1 more
TL;DR: The nearest neighbor decision rule assigns to an unclassified sample point the classification of the nearest of a set of previously classified points, so it may be said that half the classification information in an infinite sample set is contained in the nearest neighbor.
