Cluster analysis in degraded areas by erosion in the Nazareno (MG) region. Author(s): CASSARO, R.; FERREIRA, R. R. M.; FERREIRA, V. R. M.; RODRIGUES, V. G. S. Abstract: When analyzing a database, summarize collected information is the analyst main challenge. In many cases, when you have a large number of data, it may be of interest to create groups. A clust... ... Repository: BDPA Publication year: 2021
Cluster analysis to select peanut drought tolerance lines. Author(s): PEREIRA, J. W. DE L.; SILVA, E. C. A. DA; NOGUEIRA, R. J. M. C.; MELO FILHO, P. DE A.; LIMA, L. M. de; SANTOS, R. C. dos The breeding programs focused on semiarid environments significantly invest on selection of early-mature genotypes with the ability to maintain yield at reasonable levels, when drought sets in. The fa... ... Repository: BDPA Publication year: 2015
Streamlined approaches for image classification using principal component analysis and hierarchical clustering of extrudates from coffee and sorghum blends. Author(s): CARVALHO, C. W. P. de; FREITAS-SILVA, O. This article describes simple methods to group images including principal component analysis (PCA) and hierarchical clustering of principal components (HCPC). Images of expanded and low expanded extru... ... Repository: BDPA Publication year: 2023
Cluster analysis of breeding values for milk yield and lactation persistency in Guzerá cattle. Author(s): CRUZ, D. A. C. da; SAVEGNAGO, R. P.; SANTANA, A. B. B.; PEIXOTO, M. G. C. D.; BRUNELI, F. A. T.; FARO, L. El ABSTRACT - The aim of this study was to explore the pattern of genetic lactation curves of Guzerá cattle using cluster analysis. Test-day milk yields of 5,274 first-lactation Guzerá cows were recorded... ... Repository: BDPA Publication year: 2016
SNP clustering on DBSCAN and sensitivity analysis. Author(s): SILVA, M. V. G. B.; ARBEX, W. A. Repository: BDPA Publication year: 2014
Non-hierarchical cluster analysis for body weight, age at first egg, egg production and egg weight in a laying hen strain. Repository: BDPA Publication year: 2016
Wavelet analysis and hierarchical clustering of ofm phenotypic population's variations originated from southern america and europe and attempts of a first relation to molecular divergence. Author(s): NAVA, D. E.; BOTTON, M. In this work we compare Grapholita molesta Busck (Lepidoptera: Tortricidae) populations originated from Brazil, Chile, Spain, Italy and Greece using power spectral density and phylogenetic analysis to... ...

Classifying hybrids of energy cane for production of bioethanol and cogeneration of biomass-based electricity by principal component analysis-linked fuzzy c-means clustering algorithm. Author(s): MAY, A. Abstract: The biggest challenge facing in sugar-energy plants is to move towards the biorefinery concept, without threatening the environment and health. Energy cane is the state-of-the-art of smart e... ... Repository: BDPA Publication year: 2019

Comparison between cluster methods using simultaneous analysis of qualitative and quantitative data in bananas. Author(s): LEDO, C. A. da S.; ROQUE, R. L.; AMORIM, T. B.; GONÇALVES, Z. S.; FERREIRA, C. F.; AMORIM, E. P. Understanding the genetic variability in germplasm banks is essential to genetic breeding programs. Usually quantification of the variability is carried out using quantitative and qualitative data sep... ... Repository: BDPA Publication year: 2014
