ait should also be noted that the flexural modulus of highly anisotropic laminates is a strong function of ply - stacking sequence and will not necessarily correlate with tensile modulus, 应该也注意到它, flexural模数的高度非均质性碾压是一层的一个强的作用-堆积序列,并且必要不会关联与拉伸模数, [...
The formation of involute and the derivation ofinvolute functionhas been introduced. 介绍了渐开线的形成及渐开线函数的推导,分别运用牛顿迭代和普通迭代法,给出了符合误差精度要求的反渐开线函数的全区段(0,π/2)求解公式,并将这两种类型的求解公式编写成DELPHI和Excel表格单元计算程序,使原本复杂繁琐的反渐开线函数...
which ants harvest as a nutrient-rich food source, especially when other types of food aren't readily available. The ants stick around and protect the treehoppers from predators, but they also provide a secondary function of preventing the buildup...

α′, β′, and γ′ are the fitting parameters; λ is the additional fitting parameter to take into account the asymmetric shape of the function; δ′ and δ′ + α′ represent the minimum and maximum value of E*; β and γ describe the shape of the GLS model as depicted in Figure...
where Γ(x) is again the gamma function. See [14] for the steps of its derivation. Note that Γ(x) is readily available in Microsoft Excel® (version 16.16.8, Microsoft, Redmond, WA, USA, 2016). When Equations (2) and (4) are combined, the coefficient of variation, CV, is defi...
An activation function, F(·), to bound the output amplitude; A bias bk to increase or decrease the net input of the activation function (a horizontal translation of the activation function graph); An output of the network yk (see Figure 1b). In general, a k neuron output of an ANN ...
Similarly, standard deviation, S, is given by [3,11,13,14]: S = σo [Γ(1 + 2/m) − (Γ(1 + 1/m))2]0.5, (4) where Γ(x) is again the gamma function. See [14] for the steps of its derivation. Note that Γ(x) is readily available in Microsoft Excel® (version ...
