HEIGHT OF HYDRAULIC FRACTURE ZONE BASED ON PSO_LSSVM MODEL

Height of Hydraulic Fracture Zone Based on PSO_LSSVM Model

Predicting the height of water conducting fracture zones diffusore ambiente can prevent mine water damage and increase the upper limit of mine mining.To achieve its effective prediction, this study selects four main control parameters for prediction, including the proportion coefficient of hard rock in the overlying strata, the inclination distance

Individuality in harpsichord performance: Disentangling performer- and piece-specific influences on interpretive choices

Although a growing body of research has examined issues related to individuality in music performance, few studies have attempted to quantify markers of individuality that transcend pieces and musical styles.This study aims to identify such meta-markers by discriminating between influences linked to specific pieces or interpretive goals and perform
