A new neural network is proposed in this paper for solving quadratic programming problems with equality and inequality constraints. Comparing with the existing neural networks for solving such problems, the proposed neural network has fewer neurons and an one-layer architecture. The proposed...

In this paper, we determine the eccentric connectivity index and augmented eccentric connectivity index of fan graph, wheel graph, gear fan graph, gear wheel graph and their r-corona graphs.

Research on price transmission in vertically markets models the various price data, production index, consumer index and expectations index to proof market integration relations and estimate price transmission cycles, as well as to find out its function mechanism. Thanks to the development of...

A logistic growth model driven by additive and multiplicative noises which are correlated with each other is investigated. Using the Novikov theorem and the projection operator method, we obtain the analytic expressions of the stationary probability distribution pst(x), the relaxation time Tc,...

Electro-sorption is an effective strategy to remove metal ions from aqueous solution without being polluted by chemical reagents. It has been used in water purification and desalination, but there is little research on the recovery of rare earth. In this article, sodium diphenylamine sulfonate...
