Resumo: | The scientific interest in studies that use recurrence analysis to approach the transitions between regular and chaotic behaviors, as well as, in the identification of structures of dynamic systems, has spread over the years. Among the main tools of this analysis, we highlight the Recurrence Graph method and the Recurrence Quantification Analysis, which are widely used in the analysis of time series supposedly coming from non-linear and even non-stationary dynamic systems. In particular, this work analyzed or evaluated the large and small scale patterns in the Recurrence Graphs of the series of hot pixels in the Amazon, Cerrado, Caatinga and Atlantic Forest biomes and to obtain the quantitative measures by the method of Recurrence Quantification Analysis. Daily series of hot pixels derived from data provided by National Institute of Space Research – INPE, of the biomes were analyzed for the period from July 4, 2002 to December 31, 2019. In Brazil, the annual average of number of hot pixels, between 2002 and 2019, is approximately 241,866 detections, being these most frequent events between the months of July to October. Considering the absolute values referring to the number of hot pixels in each biome, the highest concentration occurs in the Amazon biome, as it has the largest territorial extension, however, considering the number of hot pixels and the area of each biome, the Cerrado has the highest record per 𝑘𝑚2. The structures present in the Recurrence Graphs of the daily series of hot pixels of the biomes indicate low predictability, while for the series of anomalies, they indicate high predictability, in addition to presenting abrupt changes in the dynamics of the systems in both cases. The values of the various indices that serve as measures of process quantification confirm these results, were obtained through the application of the Recurrence Quantification Analysis method. |

Dissertação (Programa de Pós-Graduação em Biometria e Estatística Aplicada) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/8768The scientific interest in studies that use recurrence analysis to approach the transitions between regular and chaotic behaviors, as well as, in the identification of structures of dynamic systems, has spread over the years. Among the main tools of this analysis, we highlight the Recurrence Graph method and the Recurrence Quantification Analysis, which are widely used in the analysis of time series supposedly coming from non-linear and even non-stationary dynamic systems.

Dentre as principais ferramentas desta análise, destacam-se o método Gráfico de Recorrência e a Análise de Quantificação de Recorrência, que são constantemente empregadas na análise de séries temporais supostamente provenientes de sistemas dinâmicos não-lineares e até não-estácionarios. Em particular, este trabalho buscou analisar os padrões de larga e pequena escala nos Gráficos de Recorrência das séries das queimadas nos biomas Amazônia, Cerrado, Caatinga e Mata atlântica e obter as medidas quantitativas pelo método da Análise de Quantificação de Recorrência. Foram analisadas séries diárias dos focos de calor dos biomas, registrados no período de 04 de julho de 2002 a 31 de dezembro de 2019, geradas a partir de dados disponíveis pelo Instituto Nacional de Pesquisas espaciais – INPE. No Brasil, a média anual de focos de calor, entre 2002 e 2019, é de aproximadamente 241.866 detecções, sendo esses eventos mais frequentes entre os meses de julho a outubro. Considerando os valores absolutos referentes a quantidade de focos de calor de cada bioma, a maior concentração de focos ocorre no bioma Amazônia, por ter a maior extensão territorial, no entanto, considerando a quantidades de focos de calor e a área de cada bioma, o Cerrado apresenta o maior registro por 𝑘𝑚2. As estruturas presentes nos Gráficos de Recorrência das séries diárias de focos dos biomas indicam uma baixa previsibilidade, enquanto para as séries de anomalias, indicam alta previsibilidade, além de apresentarem mudanças abruptas na dinâmica dos sistemas em ambos os casos. Os valores dos vários índices que servem como medidas de quantificação do processo confirmam esses resultados, e foram obtidos através da aplicação do método Análise de Quantificação de Recorrência.Submitted by (lucia.rodrigues@ufrpe.br) on 2022-12-14T20:33:46Z No. of bitstreams: 1 Vaniele da Silva Barros.pdf: 1997698 bytes, checksum: a18bc6d58e21416c070998f49eb98e8a (MD5)Made available in DSpace on 2022-12-14T20:33:46Z (GMT).

The scientific interest in studies that use recurrence analysis to approach the transitions between regular and chaotic behaviors, as well as, in the identification of structures of dynamic systems, has spread over the years. Among the main tools of this analysis, we highlight the Recurrence Graph method and the Recurrence Quantification Analysis, which are widely used in the analysis of time series supposedly coming from non-linear and even non-stationary dynamic systems. In particular, this work analyzed or evaluated the large and small scale patterns in the Recurrence Graphs of the series of hot pixels in the Amazon, Cerrado, Caatinga and Atlantic Forest biomes and to obtain the quantitative measures by the method of Recurrence Quantification Analysis. Daily series of hot pixels derived from data provided by National Institute of Space Research – INPE, of the biomes were analyzed for the period from July 4, 2002 to December 31, 2019. In Brazil, the annual average of number of hot pixels, between 2002 and 2019, is approximately 241,866 detections, being these most frequent events between the months of July to October. Considering the absolute values referring to the number of hot pixels in each biome, the highest concentration occurs in the Amazon biome, as it has the largest territorial extension, however, considering the number of hot pixels and the area of each biome, the Cerrado has the highest record per 𝑘𝑚2. The structures present in the Recurrence Graphs of the daily series of hot pixels of the biomes indicate low predictability, while for the series of anomalies, they indicate high predictability, in addition to presenting abrupt changes in the dynamics of the systems in both cases. The values of the various indices that serve as measures of process quantification confirm these results, were obtained through the application of the Recurrence Quantification Analysis method. |
