負責具體優化措施實施,如進行話務指標分析,信令跟蹤,參數及切換關系檢查,站點及硬體故障檢查,信號覆蓋及干擾問題檢查等等,以提升整體網路服務質量Aesthetic appearance is one of the most important criteria used by consumers in judging clothing wear performance. bagging is a kind of three - dimensional residual deformation that deteriorates garment appearance during wear and caused dissatisfaction. to understand the psychophysical mechanisms of fabric bagging perception, a method of subjectively evaluating this behavior is developed by using a series of photographs taken from bagged fabric samples. both ranking and rating scales are used as the psychological scales. the two scales are highly correlated with each other, but the rating scale provides more information than the ranking scales and can indicate perceived differences between fabrics. a linear relationship between subjective perceptions and measured residual bagging height shows that perception of fabric bagging follows stevens ? power law. residual bagging height contributes up to 94 % of the total variance in the perception of fabric bagging. the rest of the variation may be attributed to anistropic behavior during the bagging process
美觀是消費者日常服裝穿著功能中最重要的指標之一.起拱是一種外衣穿著中引起變化,令人不滿的三維殘余變形.一種主觀評價方法是從一系列起拱織物的照片來理解心理物理學規律,採用優劣排序等級和優劣評判等級兩種方法用於心理評價標度.這兩種等級互相間緊密相關,但評判等級比排序等級包含更多的信息,可以更好地區分出兩種織物間的差異.主觀評價結果與測量得到的殘余起拱高度之間線性相關,表明了織物起拱特性符合斯特藩指數定律.殘余起拱高度對織物起拱特性總方差的貢獻在94 %以上.其它可能是起拱時各向異性因素引起的Then the thesis presents two peephole optimizations for the c 、 c + + compiler based on the architecture of thump to improve the quality of generated codes. one optimization is on multimedia applications. since thump supports two mmx instructions, the optimized compiler can generate these instructions to improve the performance
論文討論了如何利用thump體系結構的特點進一步提高目標代碼生成質量的優化技術,並實現了兩種窺孔優化,包括針對thump的多媒體指令的優化演算法和基於thump的高速乘除處理部件的優化演算法。A full mathematical model of optimal flow pattern design withengineering constraints was put forward, based on modern optimal control theory. an optimal flow pattern design was presented for optimizing meridional channel of axial flow turbine. according to integral optimization of turbine stages, a full physical model and mathematical expression were put forward for proposition of optimal flow pattern, including all performance parameters in turbine stages. this problem was further recast into a typical form control to maximize specific performance index such as work or efficiency of stage with given initial state, fixed terminal condition and constraints for part of state terminal variables. the program was also worked out according penalty function method and conjugate gradient method. the optimal distribution of c1ur1 ( r1 ) was obtained according to constraint conditions and maximized objective function
把近代最優控制論方法引入軸流透平葉片的設計,在優化的軸流透平子午通道內,建立包括透平級內所有性能參量的最優流型命題的完整的物理模型及其數學表達式,並歸化為一個在給定初始狀態、自變量終端固定、部分狀態變量終端受有約束的條件下,使級的某一性能指標(如級的功率)達到最優的最優控制問題,應用「代價函數法」及「共軛梯度法」編制計算程序,計算得到符合給定約束條件、並使目標函數取極值的最優環量分佈,結果是令人滿意的。Optimization when compiling six approaches are proposed : constant embedding, constant propagation, duplication propagation, flag update elimination, conditional instruction merge and instruction scheduling
編譯期優化提出六種編譯期優化的手段:只讀常量內嵌,常量傳播,復制傳播,消除無用標志位更新,條件語句合併和指令重排。Sse and sse2 instructions will be used for some scalar floating - point computations, when it is determined that it is faster to use the sse sse2 instructions and registers rather than the x87 floating - point register stack
時,優化程序將選擇何時以及如何使用sse和sse2指令。當確定使用sse / sse2指令和寄存器肯定要比使用x87浮點寄存器堆棧更快時, sse和sse2指令將用於某些標量浮點計算。分享友人
