again, tomcat s performance deteriorated drastically at about 600 users, while the nio-based server s error rate remained relatively low 同样,在大约600个用户时,tomcat的性能急剧下降,而基于nio的服务器的错误率保持相对较低。
the newest objection, which is at the heart of the simpson defense team's argument to exclude dna evidence, is the testing lab's error rate 最新的反对理由是鉴定实验室的误差率,这也是辛普森案件中辩护队排除dna证据的论据的核心。
firstly, how to choose spreading factor of non-coherent dcsk system that minimizes the bit error rate for a given eb / n 0 is discussed in this paper 文中首先讨论了非相干dcsk系统在给定eb/n0下,如何选择扩频系数使其误码率最低问题。
so the subjective iqa can not be used widely . today image encoding pursues low error rate and high compression ratio, which needs effective iqa 客观保真度这一概念用来描述评价对象与参考图像间的相似程度,即是对图像逼真度的测量。
to process an iris image, this system needs only 0.2 second . the eer ( equal error rate ) is 3.9 % in testing the casia iris library 其中,本系统对一枚虹膜进行处理的速度小于0.2秒,在casia虹膜数据库上测试的eer(等错误概率)为3.9%。
