The Riemann-Stieltjes Integral [PDF]
Missouri Journal of Mathematical Sciences, 1994 Riemann-Stieltjes integration is an optional topic for a first course in real analysis. In this paper, we examine some of the pedagogical reasons in favor of its inclusion and some of the technical anachronisms associated with it.

Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations
International Journal for Numerical Methods in Fluids, EarlyView.The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

Approximating the Riemann-Stieltjes Integral via Some Moments of the Integrand [PDF]
, 2007 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 ...

Locally Adaptive Non‐Hydrostatic Shallow Water Extension for Moving Bottom‐Generated Waves
International Journal for Numerical Methods in Fluids, EarlyView.This study proposes a locally adaptive non‐hydrostatic model, which is based on the non‐hydrostatic extension of the shallow water equations (SWE) with a quadratic pressure relation, and applies it to wave propagation generated by a moving bottom. To obtain the locally adaptive model, we investigate several potential adaptivity criteria based on the ...

Limnology and Oceanography: Methods, EarlyView.Abstract Curcumin, a natural plant product derived from Curcuma longa, was assessed as a mitigation technique against the toxic bloom‐forming dinoflagellate Karenia brevis in two mesocosm experiments taking place in 2022 and 2024. In these experiments, curcumin was applied at a dosage of 5 mg L−1 to K.

Riemann Integral on Fractal Structures
MathematicsIn this work we start developing a Riemann-type integration theory on spaces which are equipped with a fractal structure. These topological structures have a recursive nature, which allows us to guarantee a good approximation to the true value of a ...

THE GENERALIZED RIEMANN-STIELTJES INTEGRAL [PDF]
Real Analysis Exchange, 1995 A Stieltjes type integral \(\int_Af \,dG\) of a function \(f\) with respect to a charge \(G\) in the bounded \(BV\) set \(A\subset \mathbb R^m\) is defined in the paper via Riemann type integral sums and the concept of the indefinite integral. Some specific results concerning the concept are presented.

Uncovering Hidden Resonances in Non‐Hermitian Systems with Scattering Thresholds
Laser &Photonics Reviews, EarlyView.The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non‐Hermitian systems are referred to as scattering thresholds. Close to these branch points, resonances from different Riemann sheets can tremendously impact the optical response.

Hermite-Hadamard type inequalities, convex stochastic processes and Katugampola fractional integral
Revista Integración, 2018 In this work we present some Hermite-Hadamard type inequalities for convex Stochastic Processes using the Katugampola fractional integral, and from these results specific cases are deduced for the Riemann-Liouville fractional integral and Riemann ...
