- many processes can run simultaneously without a significant performance deterioration
许多进程可以并行运行,不会有性能的明显降低。 - when the number of samples is large, it is sensible for one to use a portion of data to achieve the original objective without performance deterioration
如果样本数量巨大,那么通常的方法是从部分数据中学习,无损于性能地达到初始目标。 - the process and control engineers found that the mpc control systems perform well initially, but many factors can contribute to their abrupt or gradual performance deterioration . lacking of effective real-time monitoring and maintenance tool, some of the control systems would run poorer and pull down in the end
但是先进控制算法的工业实践者发现mpc控制系统在运行初期可以获得很好的控制效果，运行一段时间之后受各种因素的影响性能逐渐变差，加上维护上的技术难度和滞后性问题可能最终导致控制器不能正常运行而被淘汰。 - when studying the network performance, flow control and resource provisioning of communication networks, traffic model plays a very important role . the recent studies show that the date network traffic is self-similar, so the markovian model, which describes telephone networks accurately, is not suitable for date networks . the self-similarity of the network traffic has severe impact on flow control and queuing analysis in date networks, therefore it has received significant attention . in this paper, g m 1 queuing model is used to analyze the queuing performance of generic variable length packet networks for the first time . the self-similar traffic is generated by multiplexing a large set of independent pareto heavy-tailed interarrival on off sources . the simulation results show that the heavy-tailed traffic results in queuing performance deterioration for variable length packet networks, which is in accordance with the analytical results for atm switches
业务量的自相似特征显著影响网络的流量控制与排队分析，已经引起人们的极大重视。采用gm1排队模型对分组长度可变的网络的排队性能进行了分析和仿真，其中自相似业务量是通过叠加大量独立的到达间隔为pareto重尾分布的onoff源来生成的。仿真结果表明，自相似业务量导致网络的排队性能劣化，这与有关文献对atm交换的分析结果一致。 - abstract : a mathematical model describing the effect of flow nonuniformityon the performance of compact heat exchanger is provided, which is based on that one side of heat exchanger is uniformly distributed but the other is of maldistribution . the model may be expressed in two different types, i . e ., continuous model and discrete model . the former provides a method analyzing the performance deterioration of exchanger due to flow maldistribution, and the latter provides a reference to the improvement of experimental measurement . the analyzing method obtained can be used to compute the performance deterioration of compact heat exchanger due to flow maldistribution . the result is significant to the optimization of compact heat exchanger design
