A nonlinear synthesis problem of antennas according to the prescribed power (squared amplitude) radiation pattern (RP) is considered in the variational statemen
Based on the entropy weight method and the gray relational analysis method, we first calculate the weight of each index and the correlation coefficient between
We propose a mathematical model for determining the probability of meteorite origin, impacting the earth. Our method is based on axioms similar to both the comp
