Diesel and gasoline are the most used fossil fuels due to their high energy release and low
cost for engines. However, the emission of air pollutants and greenhouse gases has caused …

Gas chromatography (GC) is undoubtedly the analytical technique of choice for
compositional analysis of petroleum-based fuels. Over the past twenty years, as …

Based on near-infrared (NIR) spectroscopy, a new quantitative calibration algorithm, called
“Partial Least Squares Regression Residual Extreme Learning Machine (PLSRR-ELM)” …

Proton nuclear magnetic resonance (1 H NMR) and chemometrics were employed to detect
the adulteration of camellia oil (CAO) with 3 different cheap vegetable oils. With the intensity …

We report an application of a low-level data fusion for chemometric discrimination of crude
oil samples by usual classifications, based on the combination of data obtained by means of …

Petroleum fuels play an important role in economic society, and near-infrared analysis has
been widely used in the characterization of petroleum fuels due to its effectiveness and …

A steady and accurate model used for quality detection depends on precise data and
appropriate analytical methods. In this study, the authors applied partial least square …

The main methods for dating ballpoint pen inks in questioned documents used up to day are
based mainly on the analysis of ink volatile components. These methods have some …

In a previous work, we proposed a methodology for pair-wise discrimination of gasoline
samples by creating virtual samples based on physicochemical assays or distillation curves …

The quality control of a commercial gasoline includes the assessment of several physical-
chemical properties. The main objective of the present work is to investigate the …
