例句与用法

  • Simulation results demonstrate that at isr ( interference - to - signal ratio ) = 50db , the performance of the proposed receiver is almost the same as the receiver without interference
    计算机仿真表明,当干信比为50db时,采用该方法的误码率性能与无干扰时的误码率性能基本吻合。
  • Phase - based optimal image thresholding can deal with poor contrast , high noise to signal ratio , complex patterns , and variable modalities in the gray - scale histograms , and it can obtain very good result
    该方法能够很好的处理低对比度,高信噪比,内容复杂以及多种形状的灰度直方图的图像。
  • At first , this paper reviews the traditional currency crisis theories and the research on the early warning system ; thereby try to search for the crisis root and some important early warning indicator , and then basing on those and the kaminsky ' s early warning system of the currency crisis , i analyze statistically the thailand monthly data from 1992 to 2000 , seek the threshold of every early warning indicator , the adjusted noise - signal ratio and the early warning synthesis indicator , forecast the possibility of thailand happening the crisis in the coming 12 month with the month data in 2001 , and finally conclude that thailand would not happen the crisis in the coming 12 month
    首先本文对传统货币危机理论和近期对货币危机预警的研究进行了回顾，从而试图寻找危机的根源和一些重要的预警指标，在此基础上，运用kaminsky的货币危机早期预警方法? ?信号分析法，对泰国1992 - 2000年年间的月度数据进行了统计分析，求出每个预警指标的阈值、调整后的噪音信号比以及危机预警的综合指标，进而采用泰国2001年的月度数据对泰国未来12个月进行危机预测，最后得出泰国在未来12个月内不会发生危机。
  • Based on these models , a main - road traffic flow model with two speeds on one dimension is designed . this model simulate the situation of one road in the city , traffic lights placed on the crossing , using the computer simulation , firstly , in the case of synchronized traffic lights , we investigated the velocity and flow of the model when the initial density , the turning probabilities , the number of the traffic lights , the green to signal ratio and the period of the signal are changed , then we have advanced some meliorate measure to traffic flow ; secondly , in the case of the traffic lights " signal update delay in turn , we found the optimal matching between the period of the signal and the delay time of the traffic lights so as to the perfect velocity and the flow of the model are attained
