The problem of comparing random vectors arises in many applications. We propose three new concepts of stochastically weighted dominance for comparing random vectors X and Y. The main idea is to use a random vector V to scalarize X and Y as VTX and VTY, and subsequently use available concepts...

Development of deep high-temperature heat reservoir at Yangbajing geothermal field has very important significance for capacity expanding and sustaining of the ground power plant. The geological exploration found that there is a fractured granite heat reservoir with an average temperature of...

Based on the geological data of well DP23-1 under the EGS (enhanced geothermal system) project at Desert Peak geothermal field, we numerically investigated the heat production potential from deep HDR (hot dry rock) at this site by water circulating through a novel single vertical fracture. A...

In this paper, we use a Time-Varying Conditional Copula approach (TVCC) to model Chinese and U.S. stock markets‚ dependence structures with other financial markets. The AR-GARCH-t model is used to examine the marginals, while Normal and Generalized Joe-Clayton copula models are employed to...

In this article, we use a time-varying conditional copula approach to model Chinese and US stock markets' dependence structures with other financial markets. The Autoregressive-Generalized Autoregressive Conditional Heteroscedastic-t (AR-GARCH-t) model is used to examine the marginal...
