Approximating the Riemann-Stieltjes Integral via Some Moments of the Integrand
Error bounds in approximating the Riemann-Stieltjes integral in
terms of some moments of the integrand are given. Applications for p-convex
functions and in approximating the Finite Foureir Transform are pointed out
as well
Some Remarks on the Trapezoid Rule In Numerical Integration
In this paper, by the use of some classical results from the Theory of Inequalities, we point out quasi-trapezoid quadrature formulae for which the error of approximation is smaller than in the classical case. Examples are given to demonstrate that the bounds obtained within this paper may be tighter than the classical ones. Some applications for special means are also given
Refinements of Some Reverses of Schwarz's Inequality in 2-Inner Product Spaces and Applications for Integrals
Refinements of some recent reverse inequalities for the celebrated
Cauchy-Bunyakovsky-Schwarz inequality in 2-inner product spaces are given.
Using this framework, applications for determinantal integral inequalities are
also provided

Norm Estimates for the Difference Between Bochner's Integral and the Convex Combination of Function's Values
Norm estimates are developed between the Bochner integral of a vector-valued
function in Banach spaces having the Radon-Nikodym property and the convex
combination of function values taken on a division of the interval [a,b]
Approximation of the Stieltjes integral and applications in numerical integration
summary:Some inequalities for the Stieltjes integral and applications in numerical integration are given. The Stieltjes integral is approximated by the product of the divided difference of the integrator and the Lebesgue integral of the integrand. Bounds on the approximation error are provided. Applications to the Fourier Sine and Cosine transforms on finite intervals are mentioned as well
On inequalities of Jensen-Ostrowski type
We provide new inequalities of Jensen-Ostrowski type, by considering bounds for the magnitude of (Formula Presented), with various assumptions on the absolutely continuous function f:[a,b]→C and a μ-measurable function g, and a complex number λ. Inequalities of Ostrowski and Jensen type are obtained as special cases, by setting λ=0 and ζ=∫Ωgdμ, respectively. In particular, we obtain some bounds for the discrepancy in Jensen’s integral inequality. Applications of these inequalities for f-divergence measures are also given
