Optimization of leucomalachite green degradation through electron beam and persulfate oxidation using box-behnken design and life cycle assessment.

This study explored the treatment of Leucomalachite Green (LMG) solutions using an electron beam and sodium persulfate (NaSO), employing Box-Behnken design (BBD) to optimize operational variables such as absorbed dose, initial pH and NaSO concentration. The findings highlighted an optimal absorbed dose of 4.5 kGy, a NaSO concentration of 1.

Embedding knowledge on ontology into the corpus by topic to improve the performance of deep learning methods in sentiment analysis.

Sentiment classification, which uses deep learning algorithms, has achieved good results when tested with popular datasets. However, it will be challenging to build a corpus on new topics to train machine learning algorithms in sentiment classification with high confidence. This study proposes a method that processes embedding knowledge in the ontology of opinion datasets called knowledge processing and representation based on ontology (KPRO) to represent the significant features of the dataset into the word embedding layer of deep learning algorithms in sentiment classification.

Pesticide production wastewater treatment by Electro-Fenton using Taguchi experimental design.

In this study, the electro-Fenton (EF) method was applied to remove total organic carbon (TOC) from the pesticide production wastewater containing tricyclazole (TC). Statistical Taguchi method was used to optimize the treatment performance. Analysis of variance (ANOVA) indicated that the polynomial regression model fitted experimental data with R of 0.

Femtosecond pulse damage thresholds of dielectric coatings in vacuum.

The dielectric breakdown behavior of dielectric coatings in studied for different ambient gas pressures with femtosecond laser pulses. At 10(-7) Torr, the multiple femtosecond pulse damage threshold, Fm, is about 10% of the single pulse damage fluence F(1) for hafnia and silica films compared to about 65% and 50%, respectively, at 630 Torr. In contrast, the single-pulse damage threshold is pressure independent.
