摘要：
Numerical simulation of hybrid nanomaterial free convection with helps of CVFEM was performed. Dispersing nanomaterial can minimize the exergy loss. The modeling outputs were depicted in terms of 3D plots and contours. Because of reduction of irreversibility with inclusion of nanoparticles, hybrid nanofluid was employed. Increasing Ha results in greater X-d and it is more sensible when convection become stronger. The growth of permeability increases nanomaterial motion and reduces the exergy drop.

摘要：
In the article, we prove that the function x -> (1-x)K-P(root x) is logarithmically concave on (0, 1) if and only if p >= 7/32, the function x -> K(root x)/ log(1 + 4/root 1 - x) is convex on (0, 1) and the function x -> d(2)/dx(2) [K(root x) - log (1+ 4/root 1 - x)] is absolutely monotonic on (0,1), where K(x) = integral(pi/2)(0) (1 - x(2) sin(2) t)(-1/2) dt ( 0 < x < 1) is the complete elliptic integral of the first kind.

摘要：
In the article, we present several monotonicity theorems and inequalities for the modular equation functions ma(r) and mu a(r), and find the infinite-series formulas for m1/3(r) and m1/4(r) which depend only on r. As applications, we find several precise explicit estimates for the solution of Ramanujan's generalized modular equation.
摘要：
In this paper, we introduce a new class of functions known as coordinate strongly convex functions. We discuss the relation between strongly convex functions and coordinate strongly convex functions. Also, we present some natural properties of coordinate strongly convex functions. We present Slater’s, Jensen’s and converse of the Jensen inequalities in discrete as well as integral versions for coordinate strongly convex functions. Furthermore, we present Hermite–Hadamard’s type inequalities for coordinate strongly convex functions.

In the article, we present the best possible bounds for the weighted Holder mean of the complete p-elliptic integrals of the first and second kinds, which are the generalizations of the previously results for the complete elliptic integrals. (C) 2019 Published by Elsevier Inc.

摘要：
In the article, we establish an inequality for Csiszár divergence associated with s-convex functions, present several inequalities for Kullback–Leibler, Renyi, Hellinger, Chi-square, Jeffery’s, and variational distance divergences by using particular s-convex functions in the Csiszár divergence. We also provide new bounds for Bhattacharyya divergence.

摘要：
In this paper, we present the necessary and sufficient condition for the monotonicity of the quotient of power series. As applications, some gaps and misquotations in certain published articles are pointed out and corrected, and some known results involving the Landen inequalities for zero-balanced hypergeometric functions are Improved.

We find the greatest value α

1 and β
2, such that the double inequalities α

S(a,b) + (1 − α
1) A(a,b) < T(a,b) < β

S(a,b) + (1 − β
1) A(a,b) and
$S^{\alpha_{2}}(a,b)A^{1-\alpha_{2}}(a,b)< T(a,b)< S^{\beta_{2}}(a,b)A^{1-\beta_{2}}(a,b)$
hold for all a,b > 0 with a ≠ b. As applications, we get two new bounds for the complete elliptic integral of the second kind in terms of elementary functions. Here, S(a,b) = [(a
2 + b
2)/2]1/2, A(a,b) = (a + b)/2, and
$T(a,b)=\frac{2}{\pi}\int\limits_{0}^{{\pi}/{2}}\sqrt{a^2{\cos^2{\theta}}+b^2{\sin^2{\theta}}}{\rm d}\theta$
denote the root-square, arithmetic, and Toader means of two positive numbers a and b, respectively.
