2020 International Association of Engineers.In this paper, a algorithm of the partial derivatives of the generalized hypergeometric function pFq (~a;~b; z) is obtained, where ~a = [a1; a2...ap] ~b = [b1; b2..., bq]: Moreover, we compare some algorithms of calculating the partial ...
partial derivatives of the output in relation to the input variables; (ii) the 'Weights'method is a computation using the connection weights of the backpropagation Artificial Neural Networks; (iii) the 'Perturb'method analyses the effect of a perturbation of the input variables on the output ...
On approximation of smooth functions from samples of partial derivatives with application to phase unwrapping This paper addresses the problem of approximating smooth bivariate functions from the samples of their partial derivatives. The approximation is carried ou... O Michailovich,A Tannenbaum - 《Sign...

The partial derivatives of the performance function with respect to random variable can be calculated easily with this method. The traditional safety factor method can be combined with probabilistic analysis and be complemented each other. An example is given.关键词: 函数连分式 斜坡稳定性 安全系数 ...
Boundary conditions involving higher order derivatives are presented for simulating surfaces whose reflection coefficients are known analytically, numerically, or experimentally. Procedures for determining the coefficients of the derivatives are discussed, along with the effect of displacing the surface where th...
Partial desorption by SAP particles could be considered negligible in this investigation with respect to rheological behavior. At 20 °C and 30 °C the SAP seemed to impair the formation of a lubricating layer in the SHCC during pumping and as well to change its properties, leading to a ...
This ability improves the speed of the algorithm because unlike conventional methods, the proposed method does not require calculating partial derivatives and inverse Jacobian matrix. The proposed method includes all types of buses, i.e. PQ, PV and Slack buses. The probability density function and ...
