Raman analysis and paraconsistent logic for the analysis and decision-making on the degree of adulteration of type C gasoline Claudio Luiz Firmino, Landulfo Silveira Jr, Marcos Tadeu T. Pacheco

Abstract

Raman spectroscopy in conjunction with Paraconsistent Annotated Logic with annotation of two values can be used to test the quality of gasoline C commonly used in automobiles. The process consists from the analysis of a fuel collection used as a standard, it can be compared with analyzes made on other samples from different sources (fuel stations), and later, through the non-classical logic called Paraconsistent Annotated Logic with annotation of 2 values (PAL2v) method used for decision making it is possible to obtain the degree of certainty and the degree of uncertainty, that is, evidence of how close the samples are to the standardized samples. In order for spectroscopy to perform a successful analysis, it is necessary to remove all, or at least remove as much interference as possible in the signal obtained in the collection. These interferences are classified as fluorescence, thermal noise, shot noise, cosmic rays and low resolution. The purpose of this article is it is through simulator programs to compare pure Spectro with Noise Spectro and create degrees of evidence for using the two-value paraconsistent logic-based processes to make the comparisons.
