Simulation of robust adaptive regression multi-level models for quality analysis of special coffees in cold storage. Author(s): MANOEL, I. dos S.; RESENDE, M.; SOUSA, P. H. A.; ROSA, S. D. V. F. da; CIRILLO, M. A. ABSTRACT. Numerous factors contribute to specialty coffee quality, storage and cooling conditions. We may therefore assume that sensory evaluation results can be corrupted by measurement errors, espec... ... Repository: BDPA Publication year: 2024
Mixed-Species allometric equations to quantify stem volume and tree biomass in Dry Afromontane Forest of Ethiopia. Author(s): TESHOME, M.; TORRES, C. M. M. E.; SILESHI, G. W.; MATTOS, P. P. de; BRAZ, E. M.; TEMESGEN, H.; ROCHA, S. J. S. S. da; ALEBACHEW, M. ABSTRACT. Volume and biomass equations are essential tools to determine forest productivity and enable forest managers to make informed ecisions. However, volume and biomass estimation equations are s... ...

Uso do LiDAR para quantificação da perda de biomassa produzida pelo corte de árvores e extração das toras em uma floresta tropical manejada no Estado do Acre. Author(s): QUEIROZ, A. M. de; OLIVEIRA, M. V. N. d'; OLIVEIRA, L. C. de; FIGUEIREDO, E. O. Monitoring forest operations on logged areas is essential to identify the impacts caused to the residual. Light Detection and Ranging (LiDAR) has proven an effective tool to the quantification of the... ... Repository: BDPA Publication year: 2017
A study on CNN-based detection of psyllids in sticky traps using multiple image data sources. Author(s): BARBEDO, J. G. A.; CASTRO, G. B. Abstract: Deep learning architectures like Convolutional Neural Networks (CNNs) are quickly becoming the standard for detecting and counting objects in digital images. However, most of the experiments... ... Repository: BDPA Publication year: 2020
A comparison of regression methods based on dimensional reduction for genomic prediction. Author(s): COSTA, J. A. da; AZEVEDO, C. F.; NASCIMENTO, M.; SILVA, F. F. e; RESENDE, M. D. V. de; NASCIMENTO, A. C. C. multicollinearity and high dimensionality problems, making it impossible to obtain stable estimates through the traditional method of estimation based on ordinary least squares. To overcome such chall... ... Repository: BDPA Publication year: 2021
A non-archimedean dea model to assess group comparisons. Author(s): SOUZA, G. da S. e; GOMES, E. G. We consider the use of the non-Archimedean infinitesimal epsilon in DEA-CCR models. The application of interest is defined by the performance measure of the Brazilian Agricultural Research Corporation... ... Repository: BDPA Publication year: 2016
Assessing the determinants of rural income dispersion in Brazil. Author(s): SOUZA, G. da S. e; GOMES, E. G.; ALVES, E. R. de A.
