Daily surveillance of COVID-19 using the prospective space-time scan statistic in the United States
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first discovered in late 2019 in
Wuhan City, China. The virus may cause novel coronavirus disease 2019 (COVID-19) in symptomatic individuals. Since ...
Análise de fronteiras geográficas e limites no processo temporal para avaliação de conglomerados espaço-temporais
(Universidade Federal de Minas GeraisUFMG, 2016-02-29)
Research into space-time clusters has become a subject of broad interest in scientific research. The speed of propagation of several phenomena has encouraged this interest. Particularly, associated studies with formation ...
Prospective space–time surveillance with cumulative surfaces for geographical identification of the emerging cluster

Persistent homology for time series and spatial data clustering
(Pergamon/ElsevierOxford, 2015-09)
Topology is the branch of mathematics that studies how objects relate to one another for their qualitative structural properties, such as connectivity and shape. In this paper, we present an approach for data clustering ...
The detection of spatial clusters: graph and dynamic programming based methods
(Universidade Federal de Minas GeraisUFMG, 2011-07-01)
This thesis addresses the spatial and space-time cluster detection problem. Two algorithms to solve the typical problem for spatial data sets are proposed. A fast method for the detection and inference of point data set ...
Space–time dynamics of a triple epidemic: dengue, chikungunya and Zika clusters in the city of Rio de Janeiro

Hierarchical density estimates for data clustering, visualization, and outlier detection
(ACMNew York, 2015-07)
An integrated framework for density-based cluster analysis, outlier detection, and data visualization is introduced in this article. The main module consists of an algorithm to compute hierarchical estimates of the level ...
An objective reconstruction of the chain of contagion
(1984-12-01)
North's clustering method, which is based on a much used ecological model, the nearest neighbor distance, was applied to the objective reconstruction of the chain of household-to-household transmission of variola minor ...
