It highlights the main technical documents required Federal legislation obtain authorization. These and their singularities were compiled based on study of laws, other normative instruments scientific literature. The law describes five authorizations, which two c...

Nowadays, estimating the ampere consumption and achieve to the optimum condition from the perspective of energy consumption is one of the most important steps to reduce the production costs. In this research it is tried to develop an accurate model for estimating the ampere consumption by using the artificial neural networks (ANN).In the first step, experimental studies were carried out on 7 ca...

For 0 < p < ∞, the optimal Lp rate of convergence of a nonparametric estimate of m is of order n −k 2k+d when m is assumed to be a k-times differentiable function and for p = ∞, the optimal rate is (n−1 log n) k 2k+d (see, Stone (1985)). This rate of convergence which depends on the dimension d of the covariable X becomes worse as the dimensionality of the problem increases. In the literature, ...
