The influences of the PbO-B2O3-CuV2O6 (PBC) additives on the microwave dielectric properties of (Pb0.5Ca0.5) (Fe0.5Nb0.5)O3 (PCFN) ceramics were investigated as
An interval Padé-type approximation is introduced and then Routh-Padé-type method (IRPTM) is presented to model reduction in interval systems. The denominator
