BACKGROUND There is considerable uncertainty in the disease rate estimation for aggregated area maps, especially for small population areas. As a consequence the delineation of local clustering is subject to substantial variation. Consider the most likely disease cluster produced by any given method, like SaTScan, for the detection and inference of spatial(More)
Campo rupestre is a kind of Brazilian rocky outcrop with high biodiversity and many endemic and threatened species. It occurs mainly in the Espinhaço Range in a contact region between Cerrado and/or Caatinga and Atlantic Forest. The Espinhaço Range is recognized as a region with the highest floristic diversity in South America and with many endemic species,(More)
one year and two days after the massacre of landless farmworkers at Eldorado do Carajás, Pará, Brazil. I am grateful to Cláudio Nascimento for keeping me supplied with information; to Maria Abstract The Brazilian Landless Farmworkers' Movement (MST) occupies idle farmland and demands that it be expropriated under the terms of Brazil's agrarian reform law.(More)
Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the agencies. ABSTRACT We propose a novel scan statistic algorithm for finding spatial clusters in a map divided in a finite number of regions, whose adjacency is defined by a graph structure. Instead(More)
This letter proposes a new time domain speech enhancement technique for signals corrupted by nonstationary acoustic noises. In this method, the noise components are detected and attenuated directly from the corrupted speech samples. They are obtained with a robust estimation of the noise standard deviation considering any speech and noise amplitude(More)
reproduction in any medium, provided the original work is properly cited. Objective We present a new approach to the circular scan method [1] that uses the flow of people to detect and infer clusters of regions with high incidence of some event randomly distributed in a map. We use a real database of homicides cases in Minas Gerais state, in southeast(More)
