Equality condition of retaining the independence of normal random variables under linear transformation 正態隨機向量線性變換獨立不變性的充要條件
In enforcement plan , the beam and protect plate , and random resistance are analyzed , in which the normal random variable and maximum stress element as evaluation standard are considered 研究了爐墻的改造,梁和護板的改造、腐蝕嚴重的部位的加固方案,分析了梁、柱改造方案的隨機抗力。
Based on the approach of turning some of the relevant extreme - value - type and logarithmic normal distribution variables into independent and normal random variables , the shear - slipping failure probability of a high arch dam is worked out to be of the order of magnitude of 10 ^ ( - 5 ) by means of second - order moment method 在將部分相關的極值型與對數正態分布隨機變量轉換為獨立、正態隨機變量的基礎上,利用二階矩法計算得到某高拱壩的剪滑失效概率為10 ^ ( - 5 )量級。
Time domain noise is simulated by the mathematical pseudo uniform or normal random variable and coupled to deterministic signals such as rectangular ( rect ) , triangular ( tria ) , unit step exponential ( uexp ) , even exponential ( eexp ) , or gaussian ( gauss ) pulse voltages in finite number of time samples in finite time period 用數學類真均勻或常態隨機變數模擬時域雜訊,與定然時域訊號如,方形、三角、指數遞減、或高斯等電壓脈波在有限時域?圍之有限個時域取樣結合。
