In the article, we present the sharp bounds for the Neuman mean N-AG(a, b), N-GA(a, b), N-QA(a, b) and N-AQ(a, b) in terms of the convex combinations of the arithmetic and one-parameter harmonic and contraharmonic means. As applications, we find several sharp inequalities for the first Seiffert, second Seiffert, Neuman-Sandor and logarith...
