Os seres humanos identificam naturalmente outros seres humanos utilizando suas características físicas, fisiológicas ou comportamentais. Dentre essas características, destacam-se os traços faciais. O avanço tecnológico na área de Biometria tem promovido o desenvolvimento de inúmeras técnicas para o reconhecimento automático de faces por meio de computadores, entretanto, existem ainda vários fatores que dificultam esta aplicação, como por exemplo, a variação das condições de iluminação. O objetivo deste artigo é analisar os efeitos da aplicação de um filtro de processamento de imagens, denominado Transformada Census, em uma base de dados com imagens da face em diferentes condições de iluminação. Assim, experimentos foram realizados utilizando a técnica PCA com imagens da base de dados AR antes e depois da aplicação da Transformada Census. Os resultados desses experimentos mostraram que a aplicação da Transformada Census melhorou o resultado do reconhecimento das faces, reduzindo a taxa de erro.

Brazilian folklore is rich in legends that inhabit in the imaginary of people and are believed to have originated among Brazilian indigenous peoples and the Africans who were enslaved by Portuguese settlers. However, when those stories are compared with the legends of the Iberian Peninsula , one can notice that a lot of elements in the Brazilian legends clearly reflect, for example, aspects of the popular narratives from Galicia and Portugal, such as “The moors” and “Yara’s legend”; “O trasno” and “Saci pererê”. The objective of this paper is to analyze those cultural traces by means of Comparative Literary and Intertextuality analysis, by observing how the context , the ruling ideology, and both social and cultural aspects retake the stories that are known to a certain culture and readapt them according to the traditions of another, thus producing new discourse-texts with local characteristics.

The Paraná Magmatic Province was generated by a large volcanic event occurred in the Lower Cretaceous, it was a phenomenon that preceded the fragmentation of the supercontinent Gondwana. In Brazil the volcanic rocks overlying about 75% of the surface of the Parana basin being the Serra Geral Formation essentially represented by basalts and andesites of tholeiitic nature and subordinate porphyritic rhyodacites, called Chapecó type and aphyric rhyolites, Palms type. Based on the chemical compositions, rocks of Palmas type are subdivided into Santa Maria, Clevelândia, Caxias do Sul, Jacuí and Anita Garibaldi. Rocks of Chapecó type are grouped into three distinct subtypes called Guarapuava, Tamarana and Ourinhos. These acidic rocks that overlying basalts are of two main types: high-Ti (Paranapanema, Pitanga and Urubici) and low-Ti (Gramado, Esmeralda and Ribeira). Representative profiles of these rocks were studied in detail in order to establish the lithostratigraphy and Chemostratigraphy of Palmas and Chapecó type. To do this was made a field work and the use of a database with 1109 samples with their geographical coordinates and geochemical information of major and trace elements, which were launched in maps generated by Google Earth. From these maps, it was verified that rocks of the Palmas type are distributed predominantly in the south region of the basin in the state of Rio Grande do Sul, accumulated along Torres Syncline, while those Chapecó type occur in the plateaus of midwestern Paraná, in this region was observed that Chapecó type overlap those Palmas type. In the profiles studied, within Palmas type, Caxias do Sul type is spread throughout the southern region of the basin, occurring at the base of the acid volcanic sequences, in other words, they are older compared to the others. It was also observed that the rocks of Santa Maria and Anita Garibaldi type occupy the top of the sequences, both covering rocks of Caxias do Sul..
