Mutual fund managers' frequent replacement implies fund companies' recognition to their skills. In order to capture this kind of managerial skills, we put forward two propositions: performance persistence is stronger in large fund and fund abnormal return is negatively correlated with managerial tenure. Using a panel of 96 actively managed Chinese equity funds, we document evidence consistent with...
It mainly introduces that proportional decompression valve which substitutes for original PPC valve is used as priority valve to make up of digital electro-hydraulic proportional directional valve with multiple unit valve, which fulfills digitized electro-hydraulic proportional control for bulldozer working device. First apply Simulink in the software MATLAB to simulate the dynamic characteristic...
In this paper, we present an adaptive refinement ratio algorithm for structured adaptive mesh refinement (SAMR) method based on SAMRAI framework. We developed our algorithm based on an example application program of SAMRAI framework, an AMR Euler gas dynamics application. The Euler class of this application provides routines for a sample application code that solves the Euler equations of gas dynamics...
