By the complete discrimination system for polynomials, we classify exact traveling wave solutions to the Zhiber-Shabat equation, and compute some new traveling
In this paper, we present a method for ranking extreme efficient decision making units (DMUs) in data envelopment analysis (DEA) models based on measuring dista
Moments and cumulants are commonly used to characterize the probability distribution or observed data set. The use of the moment method of parameter estimation
