简介:为网络交通,WPANFIS,它为多决定分析依靠小浪包变换(WPT)和适应neuro模糊的推理系统(ANFIS)的预言的新奇方法论在这篇文章被建议。在网络交通的自我类似的普遍存在在更早的研究被表明了,它展出长期的依赖(LRD)和短范围依赖(SRD)。另外,小浪分解是为LRDdecorrelation的一个有效工具,这被显示出。新方法把WPT用作装decoorrelateLRD并且让更多精确在原来的交通的高周波的节划分的小浪变换的扩展。然后,能从原来的交通提取有用信息的ANFIS为每个分解非静止的小浪系数的更好的预言性能在这研究被实现。模拟结果证明建议WPANFIS能在真实网络交通环境完成高预言精确性。

简介:摘要:目的 研究MNSs血型系统中NN型在三明地区无偿献血人群的分布情况及抗-M患者的临床输血。方法 随机抽取三明市血站无偿献血人群A型540例、B型352例、O型715例,以血型血清学方法检测其红细胞膜上M抗原来分析并统计NN型的分布情况。结果 NN型比例为24.0%,其中A型中NN型135例占25.0%、B型中NN型71例占20.2%,O型中NN型180例占25.2%。结论 MNSs系统中NN型在A、B、O血型中分布无明显差异且NN型在三明地区无偿献血人员的比例为24.0%。抗-M患者的输血,在24.0%的配血相合率下,应当尽量优先选择NN型的红细胞经交叉配血相容后输注,这对输血安全有重大意义。
