It is physics based and is only determined by the DNL error of analog-to-digital converter device itself. From the experimental results, this algorithm slightly improves both noise performance and energy resolution, while greatly reduces the testing errors by almost a half compared to their original values. In addition, the reduced-x^2 statistic for evaluating the Gaussian fitting goodness is significantly reduced by almost two orders after smoothing. As a typical verification example,this algorithm is successfully applied in the ground calibration of the Low Energy X-ray Instrument onboard the Hard X-ray Modulation Telescope(HXMT-LE) satellite,lending it a powerful, nondestructive and low-cost tool for both calibration and data processing for high-energy particle detector systems.展开更多

Everyday Use is regarded as Alice Walker's best-written short story. The prevailing opinion among the critics about this story is that Dee is the traitor of black American's cultural heritage, and the mother and Maggie are the hope of true value of the African Americans' tradition and heritage; however, after considering the historical and cultural background of the story, we may safely come to the conclusion that Dee actually took the first step toward the awakening of self-consciousness of the African Americans women.展开更多
