They're not going to be buying more staplers unless they're diamond-encrusted ones, and they won't be buying more paper weights unless they are customized little gold replicas of themselves.

This paper establishes a synthetic evaluation index system of the urban rail transit transfer hinge with AHP method, quantifies the index system and gives different weights to all evaluation indexes.

This paper applies parallel tangents of nonlinear programming during the weights training of neural network and puts forward a neural network in view of fast learning algorithm.
