Non-destructive genotypes classification and oil content prediction using near-infrared spectroscopy and chemometric tools in soybean breeding program
(2020-08-01)
In soybean (Glycine max L.) breeding programs, segregation is normally observed, and it is not possible to have replicates of individuals because each genotype is a unique copy. Therefore, near-infrared spectroscopy (NIRS) ...
Classification of jaboticaba fruits at three maturity stages using NIRS and LDA
(2016-03-21)
This study proposes a rapid and non-destructive method of jaboticaba [Myrciaria cauliflora (Mart.) O. Berg] fruit classification at three maturity stages based on the skin colour (immature - fruit completely green, ...
Determination of the geographical origin and ethanol content of Brazilian sugarcane spirit using near-infrared spectroscopy coupled with discriminant analysis
(2016-07-28)
Aguardente is a typical Brazilian spirit produced by the distillation of sugarcane. The valorisation of this spirit can be attributed to its notoriety, related to its production origin which can influence its quality. ...
Using a simple digital camera and SPA-LDA modeling to screen teas
(Royal Society of Chemistry, 2012-07)
Classification or screening analysis of natural unprocessed teas using simple digital images and a variable selection algorithm is described. The proposed methodology uses color histograms generated on free downloadable ...
Screening analysis of biodiesel feedstock using UV-vis, NIR and synchronous fluorescence spectrometries and the successive projections algorithm
(Elsevier Science, 2012-08)
This paper investigates the use of UV-vis, near infrared (NIR) and synchronous fluorescence (SF) spectrometries coupled with multivariate classification methods to discriminate biodiesel samples with respect to the base ...
