XGAMMA(x) = gamma function at x even when x is negativeLowerGamma(x, a) = lower incomplete gamma function γ(x, a)UpperGamma(x, a) = upper incomplete gamma function Γ(x, a)These functions can be calculated in standard Excel as follows:...
xgamma allows X users to query and alter the gamma correction of a monitor via the X video mode extension (XFree86-VidModeExtension). Note that the xgamma utility
X/gamma;-ray emission from hot accretion flows in AGNsX/gamma;-ray emission from hot accretion flows in AGNsWe present preliminary results of our study of the impact of strong gravity effects on properties of the high energy radiation produced in accretion flows around supermassive black holes....
We prove that the functional inequality $$Gamma(x)Gamma(y)leqGamma(xGamma(y)^{alpha}+yGamma(x)^{beta})$$holds for all positive real numbers x and y if and only if $$alpha=beta=frac{1}{gamma(1-gamma)}=4.09772ldots. $$Here, u03b3 denotes Euler's constant.doi:10.1142/S...

1回答 如何纠正外部屏幕上的伽马色?Linux膝上型计算机 、、 我有一台笔记本电脑,我想纠正我的外部屏幕上的伽马色。在选项系统->Preferences->监视器中,我关闭了笔记本电脑的屏幕。但是bash-命令xgamma -gamma 5没有任何影响。顺便说一句,笔记本电脑也是(如果它会打开的话)。我怎么弄到它? 浏览0提问于2012-07-27...
应力强度模型可靠度是可靠性分析里的一个重要问题, 论文运用了两种估计方法对逆Xgamma分布的应力强度模型可靠度进行了近似计算. 假定服从逆Xgamma分布的应力随机变量和强度随机变量相互独立, 通过计算得到可靠度的表达式. 由极大似然原理, 在完全数据下通过牛顿-拉夫逊算法对对数似然函数的一阶偏导数进行迭代, 得到可靠...
可靠度逆xgamma分布牛顿-拉夫逊算法极大似然估计基于极大似然方法给出了逆xgamma分布应力强度模型可靠度的点估计与置信区间,采用牛顿-拉夫逊算法给出了极大似然估计的近似解;运用参数变换后的信息阵,得到模型可靠度的渐近分布,进而给出置信区间.通过随机模拟和机载通信收发器的实例演算,结果表明:该方法是可行的,有效...
