 Author(s): AVILA, A. M. H. de; FERREIRA JÚNIOR, D.; OLIVEIRA, S. R. M. This study aimed to transform time series of annual data of precipitation of Rio Grande do Sul in homogeneous precipitation regions through clustering techniques (data mining). |
 Author(s): FARHATE, C. V. V.; SOUZA, Z. M. de; OLIVEIRA, S. R. de M.; TAVARES, R. L. M.; CARVALHO, J. L. N. Soil CO2 emissions are regarded as one of the largest flows of the global carbon cycle and small changes in their magnitude can have a large effect on the CO2 concentration in the atmosphere. Thus, a... ... |
 Author(s): LIMA, E. de S.; SOUZA, Z. M. de; OLIVEIRA, S. R. de M.; LOVERA, L. H.; FARHATE, C. V. V. Abstract - Eucalyptus plantation has expanded considerably in Brazil, especially in regions where soils have low fertility, such as in Brazilian Cerrados. To achieve greater productivity, it is essent... ... |
 Author(s): REZENDE, L. F. C.; ARENQUE-MUSA, B. C.; MOURA, M. S. B. de; AIDAR, S. de T.; RANDOW, C. V.; MENEZES, R. S. C.; OMETTO, J. P. B. H. The semiarid region of northeastern Brazil, the Caatinga, is extremely important due to its biodiversity and endemism. Measurements of plant physiology are crucial to the calibration of Dynamic Global... ... |
 Author(s): MOREIRA, C. E. S.; OLIVEIRA, A. L. R. de; OLIVEIRA, S. R. de M.; YAMAKAMI, A. The road system is the main form of transport in the biggest production regions between the domestic market and exporting. ports, as well as the transport used on intermodal routes connecting producti... ... |
 Author(s): VALE, M. M.; MOURA, D. J. de; NÄÄS, I. de A.; OLIVEIRA, S. R. de M.; RODRIGUES, L. H. A. Heat waves usually result in losses of animal production since they are exposed to thermal stress inducing an increase in mortality and consequent economical losses. Animal science and meteorological... ... |
 Author(s): SILVA, C. C. da; OLIVEIRA, S. R. de M.; ADAMI, S. F.; CRIVELENTI, R. C.; COELHO, R. M. ABSTRACT: The study had as objective to develop techniques for digital soil mapping with support of main parameters of relief descriptors, of geologic map and pedological map pre-existing of Dois Córr... ... |
 Author(s): TAVARES, R. L. M.; OLIVEIRA, S. R. de M.; BARROS, F. M. M. de; FARHATE, C. V. V.; SOUZA, Z. M. de; LA SCALA JUNIOR, N. ABSTRACT: The Random Forest algorithm is a data mining technique used for classifying attributes in order of importance to explain the variation in an attribute-target, as soil CO2 flux. This study ai... ... |
 Author(s): ROMANI, L. A. S.; TRAINA, A. J. M.; SOUSA, E. P. M. de; ZULLO JÚNIOR, J.; AVILA, A. M. H.; RODRIGUES JR. J. F.; TRAINA JÚNIOR. C. In the past few years, improvements in the data acquisition technology have decreased the time interval of data gathering. Consequently, institutions have stored huge amounts of data such as climate t... ... |
 Author(s): FARHATE, C. V. V.; SOUZA, Z. M. de; OLIVEIRA, S. R. de M.; CARVALHO, J. L. N.; LA SCALA JÚNIOR, N.; SANTOS, A. P. G. ABSTRACT: The use of data mining is a promising alternative to predict soil respiration from correlated variables. Our objective was to build a model using variable selection and decision tree inducti... ... |
