11644 基于预留机制的服务器动态开启/关闭(dynamic powering on/off servers,DPS)策略采用静态设置的任务请求数阈值,可能造成服务器状态频繁切换从而导致性能下降、能耗上升。 Reserve based on the mechanism of dynamic server open/close (dynamic powering on/off the servers, the DPS) strategy to adopt static task requests threshold, the switch may cause server status frequently resulting in performance degradation, increase energy consumption.
11645 对此,提出一种基于动态阈值的服务器唤醒策略。 ‭In this paper, a kind of server wake-up strategy based on dynamic threshold.
11646 首先,用具有不耐烦任务的排队模型对云计算系统的任务调度进行建模,分析系统中的平均任务背叛数和能耗成本,提出任务请求数阈值动态调整策略;‭ ‭First of all, with impatient task queue model of task scheduling in cloud computing system with modeling and analysis system of the average number of task betrayal and energy costs, and put forward the task requests threshold dynamic adjustment strategy; ‭
11647 然后,根据服务器所在冷点区域和当前关闭时长选择服务器进行唤醒。 Then, based on the server where the cold spot area and the current closing time select server to awaken.
11648 仿真结果表明,与基于静态阈值的服务器唤醒策略相比,本文策略能够保证任务的平均响应时间,并有效降低云计算系统的能耗开销。 ‭Simulation results show that compared with the server wake-up strategy based on static threshold, this strategy can guarantee the average response time of tasks, and effectively reduce the energy consumption of cloud computing system overhead.
11649 在高速移动环境下,宽带正交频分复用(orthogonal frequency division multiplexing,OFDM)系统在传输过程中因频率偏差都会导致严重的子载波间干扰(inter-carrier interference,ICI)。 In high-speed mobile environment, broadband orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) systems in transit due to frequency offset will lead to serious interference between subcarrier (Intel - carrier interference, ICI).
11650 本文在分析频偏导致ICI成因基础上,结合共轭消除方案和编码权值优化方案,提出一种有效的ICI自消除新方案。 In this paper, based on the analysis on causes deviation cause ICI, combined with the conjugate eliminate scheme and encoding a weight optimization scheme, proposed an effective ICI from eliminating the new scheme.
11651 仿真结果表明,所提出的方案在较大频偏范围内具有较高的载干比(carrier-to-interference ratio,CIR)和较低的误比特率(bit error rate,BER),且能有效消除传统自消除编码性能的"平层效应",进而获得了系统性能的改善。 The simulation results show that the proposed scheme in larger frequency range with high load dry than (carrier - to - interference thewire, CIR) and lower bit error rate (bit error rate and BER), and can effectively eliminate the traditional eliminate coding performance "flat layer effect", then to improve the performance of the system is obtained.
11652 军事指挥控制(command and control,C2)组织中的效能评估问题是信息化作战中研究的热点。 Military command and control, the command and control, C2) in the organization is a hotspot of research on the informationization battle effectiveness evaluation problem.
11653 首先通过分析C2组织实体间的关系,形式化描述了C2组织信息结构的基本概念。 ‭First of all, through the analysis of the relationship of C2 organization entity, formal describes the basic concept of C2 organization information structure.
