Blasting of rocks has intrinsic environmental impacts such as ground vibration, which can interfere with the safety of lives and property. Hence, accurate prediction of the environmental impacts of blasting is imperative as the empirical models are not accurate as evident in the literature. Therefore, there is need to consider some robust predictive models for accurate prediction results. Gene expression programming (GEP), adaptive neuro-fuzzy inference system (ANFIS), and sine cosine algorithm optimized artificial neu-ral network (SCA-ANN) models are proposed for predicting the blast-initiated ground vibration in five granite quarries. The input parameters into the models are the distance from the point of blasting to the point of measurement (D), the weight of charge per delay (W), rock density (ρ), and the Schmidt rebound hardness (SRH) value while peak particle velocity (PPV) is the targeted output. 100 datasets were used in developing the proposed models. The performance of the proposed models was examined using the coefficient of determination (R2) and error analysis. The R2 values obtained for the GEP, ANFIS, and SCA-ANN models are 0.989, 0.997, and 0.999, respectively, while their errors are close to zero. The proposed models are compared with an empirical model and are found to outperform the empirical model.

精英阶层的整体气质,决定了国家未来的政治与经济气象,精英阶层的再生产机制更是在很大程度上决定着一个国家的发展轨迹。本文作者结合1978年以来中国市场转型的独特形态,以“精英再生产的双轨路径”概括了中国精英阶层的再生产模式:一方面,精英地位的再生产,不管是体制精英还是市场精英,都更有可能将他们的优势地位传递给子代;另一方面,从整体上来说,体制或者市场的职业地位延续,其间存在壁垒,子代对父代优势地位的
