on a statistical average there is a strong dependence of the scintillation on the time of the day . 就統(tǒng)計(jì)平均值而言,閃爍跟一天的不同時(shí)間有很強(qiáng)的依賴關(guān)系。
in addition, robustness of the scheme against jpeg lossy compression, image enhancement, noise addition and statistical averaging attacks among others are provided 此外,文中還分析了算法對(duì)jpeg壓縮、圖像增強(qiáng)、加入噪聲及共謀攻擊等操作的魯棒性。
researchers have long noted that by melding together hundreds of faces, a statistical average of facial characteristics is reached that happens to be incredibly attractive 科學(xué)家早已發(fā)現(xiàn)通過融合幾百張臉,得到的一張統(tǒng)計(jì)學(xué)上的面部特征平均的臉,碰巧是極為富有吸引力的。
however, the optimal results being a statistical average, the antenna pattern of random phasing is unsteady with the scanning angle and scanning period, so it is not easy to form the actually needed codes for control of the antenna scanning 應(yīng)用遺傳算法對(duì)隨機(jī)饋相方案進(jìn)行優(yōu)化,能有效抑制寄生副瓣的出現(xiàn),形成掃描空域確定的波控代碼,實(shí)現(xiàn)相控陣波束無慣性的精確指向。
the coefficients corresponding to those of landau free energy are associated with some kinds of statistical average, so they are related to temperature . using the molecular interaction potential, with proper potential parameters, we also calculate the order-parameter tensors " phases which are depended on the reduced temperature 選擇一定的勢(shì)參數(shù),從分子的作用勢(shì)出發(fā),通過自洽的方法進(jìn)行數(shù)值計(jì)算,求得bp和bp的序參量張量各系數(shù)與約化溫度的關(guān)系曲線。
