A machine learning framework to predict nutrient content in valencia-orange leaf hyperspectral measurements. Author(s): OSCO, L. P.; RAMOS, A. P. M.; PINHEIRO, M. M. F.; MORIYA, E. A. S.; IMAI, N. N.; ESTRABIS, N.; IANCZYK, F.; ARAÚJO, F. F.; LIESENBERG, V.; JORGE, L. A. de C.; LI, J.; MA, L.; GONÇALVES, W. N.; MARCATO JUNIOR, J.; CRESTE, J. E. This paper presents a framework based on machine learning algorithms to predict nutrient content in leaf hyperspectral measurements. This is the first approach to evaluate macro- and micronutrient con... ... Repository: BDPA Publication year: 2020
Spatial analysis of erosive processes in plateaus and depressions of the Upper Paraguai river basin. Author(s): ANDRADE, D. D. de; SILVA, J. dos S. V. da; FIGUEIREDO, V. A.; CASTRO, E. C. de Natural characteristics may contribute to the erosion of the soil and to environmental imbalances, and in most cases, they initiate the imbalances that will be exacerbated by human activities. The pre... ... Repository: BDPA Publication year: 2017
