Use poisson equation to grid faultage datas.Computer Engineering and Applications
Faultage datas include contour line,fault line and fault section,and contour line is most important of all,but the faultage data gridding is complicated by the effect of fault line and fault section.To solve this problem efficiently,conjugate gradient method is introduced to evaluate the poisson equation of terrain in this paper,and the construction algorithm of the faultage datas is given.
Abstract This study contributes to the literature on socially responsible investing by examining the diversification potential of commodities, specifically oil, gold and clean energy together with the Brazilian Corporate Sustainability Index (ISE). Multivariate GARCH models are used to model volatility spillovers and conditional correlation in pairs of stocks containing ISE. Specifically, A-BEKK and A-DCC models with spillovers are estimated. The models’ results are used to compute and analyze the optimal weights and hedge ratios for stock portfolio holdings. The greatest benefit from diversification is obtained through the acquisition of gold and then OVX.
