Over the years, [[risk management]] has gained significant importance in [[Laboratory|laboratories]] of every kind. The safety of workers, the [[Accuracy and precision|accuracy]] and reliability of laboratory results, issues of financial sustainability, and protection of the environment play an important role in decision-making in both industry and service-based labs. In order for a laboratory to be considered reliable and safe, and therefore competitive, it is recommended to comply with the requirements of international standards and other [[Regulatory compliance|regulatory documents]], as well as use tools and risk management procedures. In this paper, [[information]] is summarized concerning the terms “risk” and “risk management,” which are then approached through the latest [[International Organization for Standardization]] (ISO) standard [[ISO 9000|ISO 9001]], [[ISO/IEC 17025]], and [[ISO 14000|ISO 14001]] standards ...

"Geochemical biodegraded oil classification using a machine learning approach"

Chromatographic oil analysis is an important step for the identification of biodegraded petroleum via peak visualization and interpretation of phenomena that explain the oil geochemistry. However, analyses of chromatogram components by geochemists are comparative, visual, and consequently slow. This article aims to improve the chromatogram analysis process performed during geochemical interpretation by proposing the use of convolutional neural networks (CNN), which are deep learning techniques widely used by big tech companies. Two hundred and twenty-one (221) chromatographic oil images from different worldwide basins (Brazil, USA, Portugal, Angola, and Venezuela) were used. The open-source software Orange Data Mining was used to process images by CNN. The CNN algorithm extracts, pixel by pixel, recurring features from the images through convolutional operations ...
