46170 结果表明，所提噪声抑制算法能应用于未知噪声特征的电力线脉冲噪声环境中，性能优于现有的脉冲噪声抑制算法。 According to the results from simulation, it is clearly demonstrated that the proposed ANMPEFC can work in power line impulse noise environment without knowing the noise characteristics and has better performance in contrast to existing impulse noise-suppression algorithm.
46171 基于某运营商骨干网上 9 亿条 HTTP 请求，分析了 HTTP 请求组成、内容长度、流行度和时间动态性，提出一种面向应用感知的骨干网缓存方法（AACM, application-aware backbone network cache method）。 Based on over 900 million HTTP requests from an ISP backbone network, the HTTP characteristic of different content types from a wide range of perspectives was analyzed, including request composition, size, popularity and temporal dynamics, and an application-aware backbone network cache method was proposed, referred to as AACM.
46172 实验结果表明在缓存空间略有增加的情况下，在线视频的内容命中率提高了 15%以上，回源流量和缓存负载这些指标降低了一半左右。 The experiment results show that in the case of a slight increase in cache space, the hit ratio of the online-video increases 15%,and the total source traffic and cache I/O load reduced by about half.
46173 将强制访问控制、自主访问控制等访问控制系统迁移为基于角色的访问控制系统可极大提高对用户权限的管理效率。 Migrating traditional access control, such as mandatory and discretionary access control, into role-based access control (RBAC) lightens a practical way to improve the user-permission management efficiency.
46174 为保证系统的安全性需要在迁移过程中生成正确的角色， To guarantee the security ofRBAC system, it is important to generate proper roles during the migration.
46175 而原系统中存在的异常权限配置给角色生成带来了极大的挑战。 However, abnormal user-permission configurations lead to wrong roles and cause tremendous security risks.
