Dual-level segmentation method for feature extraction enhancement strategy in speech emotion recognition
This study explored the possibility of using quarry dust as a replacement for natural river sand in concrete production. The behaviors of individual materials such as quarry dust (QD), ground granulated blast-furnace slag (GGBS), pulverized fly ash (PFA) and silica fume (SF) were determined. Laborat...

Laboratory investigations were also conducted to evaluate the characterization of quarry dust and by-products materials in terms of microstructure, physical and chemical properties.
