Stability and adaptability of runner peanut genotypes based on nonlinear regression and AMMI analysis. Author(s): SANTOS, R. C. dos; SILVA, A. F.; GONDIM, T. M. de S.; OLIVEIRA JUNIOR, J. O. L. de; ARAUJO NETO, R. B. de; SAGRILO, E.; VASCONCELOS, R. A. de; MELO FILHO, P. de A.; SILVA FILHO, J. L. da The objective of this work was to estimate the stability and adaptability of pod and seed yield in runner peanut genotypes based on the nonlinear regression and AMMI analysis. Yield data from 11 trial... ... Repository: BDPA Publication year: 2012
Assessing the significance of covariates in output oriented data envelopment analysis with two stage regression models. Author(s): SOUZA, G. da S. e; GOMES, E. G. We propose alternative regression models to assess the effects of covariates in output oriented DEA scores. We use probability choice models combined with specifications related to the gamma and to th... ... Repository: BDPA Publication year: 2014
An approach to genomic analysis of longitudinal data using random regression. Author(s): SANTOS, D. J.; BOISON, S. A.; UTSUNOMIYA, Y. T.; PEIXOTO, M. G. C. D.; TONHATI, H.; SÖLKNER, J.; SILVA, M. V. G. B. Repository: BDPA Publication year: 2014
Stability and adaptability of runner peanut genotypes based on nonlinear regression and AMMI analysis. Author(s): SANTOS, R. C. dos; SILVA, A. F.; GONDIM, T. M. de S.; O JUNIOR, J. O. L. de; ARAUJO NETO, R. B. de; SAGRILO, E.; VASCONCELOS, R. A. de; MELO FILHO, P. de A.; SILVA FILHO, J. L. da Repository: BDPA Publication year: 2012
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
Rapid and environmentally friendly wine analysis using Vis/NIR Spectroscopy and Support Vector Machine regression. Author(s): MARQUES, E. J. N.; BIASOTO, A. C. T.; FREITAS, S. T. de; MENEZES, T. R. de; PEREIRA, G. E.; NASSUR, R. de C. M. R.; MEDEIROS, E. P. de The aim of this study was to calibrate and validate models that can be used to determine quality parameters in red wine using Vis/NIR spectroscopy and the Least Squares Support Vector Machine (LS-SVM)... ...

Modeling enteric methane emission from beef cattle in Brazil: a proposed equation performed by principal component analysis and mixed modeling multiple regression. Author(s): MEDEIROS, S. R. de; BARIONI, L. G.; BERNDT, A.; FREUA, M. C.; ALBERTINI, T. Z.; COSTA JUNIOR, C.; FELTRIN, G. B. Brazil has the largest commercial beef cattle herd in the world but does not have its own model to predict methane (CH4 ) emission. The aim of this study was to create the first empirical enteric CH4... ... Repository: BDPA Publication year: 2014
Estimating the aboveground biomass and wood volume of savanna woodlands in Brazil's Pantanal wetlands based on allometric correlations. Author(s): SALIS, S. M.; ASSIS, A. M.; MATTOS, P. P. de; PIÃO, C. S. A. The quantity and distribution of vegetal biomass ar important aspects to consider in ecosystem studies. However, little information is available about Brazil's Pantanal woodland savannas. Thes work in... ... Repository: BDPA Publication year: 2006
The modeling and simulation of a smoke-free firewood furnace designed for indirect heating adapted to mixing heating configuration. Author(s): SILVA, L. C. da; YUSUF, K. A.; MELO, E. de C.; SOARES, S. F.; SILVA, J. de S. e; DONZELES, S. M. L.; VITOR, D. G. ABSTRACT: The use of wood furnaces for thermal energy applications in drying is common among coffee growers in Brazil. However, incomplete combustion of firewood and excessive use of damaged furnaces... ... Repository: BDPA Publication year: 2024
Management of agricultural research center in Brazil: a DEA application using a dynamic GMM approach. Author(s): SOUZA, G. da S. e; GOMES, E. G. In this paper, we measure the performance for each of the Brazilian Agricultural Research Corporation research center by means of a Data Envelopment Analysis model. Performance data are available for... ... Repository: BDPA Publication year: 2015
