Abstract:
... This paper investigates the volatility spillover among multiple energy stocks in different periods and clusters (the period of similar fluctuation) by employing the Toeplitz inverse covariance-based clustering method (TICC) and network method. Specifically, we investigate the spillover effect among energy stocks in periods and compare that in the same clusters under different events to reveal the ...

Abstract:
... When a dam breaks, huge floods will be generated that may inundate urban areas, enterprises, farmlands, and infrastructure and cause giant economic losses. Economic risk criteria are a kind of basis for determining dam risk levels and to decide whether risk control measures should be taken or not. However, compared to loss-of-life risk criteria, much fewer economic risk criteria for dams have been ...

Based on this, a Dual-diameter and bi-speed composite drilling method that can realize the different depth, diameter, and rotate speed coupling using only hole-bottom power is proposed in this paper. And a Dual-diameter and bi-speed ...
