Using Intact Nuts and Near Infrared Spectroscopy to Classify Macadamia Cultivars
Macadamia nut industry is increasingly gaining more space in the food market and the success of the industry and the quality are largely due to the selection of cultivars through macadamia nut breeding programs. Thus, the ...
Electronic band-edge structure, effective masses, and optical absorption of Si1-xGex using an extended FPLAPW/VCA/LDA+U computational method
(Sociedade Brasileira de F??sica, 2006-06)
Classification of jaboticaba fruits at three maturity stages using NIRS and LDA
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, ...
Two-dimensional linear discriminant analysis for classification of three-way chemical data
(Elsevier Science, 2016-09-28)
The two-dimensional linear discriminant analysis (2D-LDA) algorithm was originally proposed in the context of face image processing for the extraction of features with maximal discriminant power. However, despite its ...
Determination of the geographical origin and ethanol content of Brazilian sugarcane spirit using near-infrared spectroscopy coupled with discriminant analysis
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 ...
Discrimination between Myrciaria jaboticaba ('Sabará') and Myrciaria cauliflora ('Açú') fruit using CIE colour parameters and near-infrared spectroscopy
The Myrtaceae family has many species and among them stands up the Myrciaria cauliflora (DC) Berg ('Açú') and Myrciaria jaboticaba (Vell) Berg ('Sabará') due to the quality of their fruit which are called jaboticabas. ...
Topic modeling applied to business research: A latent dirichlet allocation (LDA)-based classification for organization studies
More than 1.5 million academic documents are published each year, and this trend shows an incremental tendency for the following years. One of the main challenges for the academic community is how to organize this huge ...
Aplicação de métodos analíticos não destrutivos na melhoria do processo de controle de qualidade de noz macadâmia
