Amorim, Anderson Rici [UNESP]; Visotaky, Joao Matheus Verdadeiro [UNESP]; Contessoto, Allan De Godoi [UNESP]; Neves, Leandro Alves [UNESP]Made available in DSpace on 2022-04-30T01:30:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-07-02; The multiple sequence alignment (MSA) is considered one of the most important tasks in Bioinformatics. Nevertheless, with the growth in the amount of genomic data available, it is essential the results with biological significance and an acceptable execution time. Thus, many tools have been proposed wit...

Tenguam, Jaqueline Junko [UNESP]; Rozendo, Guilherme Botazzo [UNESP]; Roberto, Guilherme Freire; Nascimento, Marcelo Zanchetta DoMade available in DSpace on 2021-06-25T10:50:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-16; Fracta1 techniques are widely explored to quantity and recognize texture patterns in digital images. Among the different types of fractal techniques, one that stands out is the Higuchi fractal dimension. The Higuchi fractal dimension allows determining how much space is filled in a two-dimensional image...
