An distributed environment for data storage and processing in support for bioinformatics analysis. Author(s): CINTRA, L. In this work, we investigate the use of a distributed file system (DFS) for data storage; associated with a distributed resource management (DRM) for control the parallel tasks execution. Repository: BDPA Publication year: 2015
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
Data analysis in social networks for agribusiness: a systematic review. Author(s): SOARES, N. D.; BRAGA, R.; DAVID, J. M. N.; SIQUEIRA, K. B.; STROELE, V.

The effects of encoding data in diversity studies and the applicability of the weighting index approach for data analysis from different molecular markers. Author(s): FERRÃO, L. F. V.; CAIXETA, E. T.; CRUZ, C. D.; SOUZA, F. de F.; FERRAO, M. A. G.; ZAMBOLIM, Z.; SAKIYAMA, N. S. The use of molecular markers to study genetic diversity represents a breakthrough in this area, because of the increase in polymorphism levels and phenotypic neutrality. Codominant markers, such as mi... ... Repository: BDPA Publication year: 2014
