About a dubious proof of a correct result about closed Newton Cotes error formulas
In this study, we comment about a wrong proof, at least incomplete, of the closed Newton Cotes error formulas for integration in a closed interval [a,b].\left[a,b].

On a Nonlinear Three-Point Subdivision Scheme Reproducing Piecewise Constant Functions
In this article, a nonlinear binary three-point non-interpolatory subdivision scheme is presented. It is based on a nonlinear perturbation of the three-point subdivision scheme: A new three point approximating C2 subdivision scheme, where the convergence

Analysis of a New Nonlinear Interpolatory Subdivision Scheme on σ Quasi-Uniform Grids
In this paper, we introduce and analyze the behavior of a nonlinear subdivision operator called PPH, which comes from its associated PPH nonlinear reconstruction operator on nonuniform grids.

In this paper, we analyze the behavior of a nonlinear reconstruction operator called PPH around discontinuities. The acronym PPH stands for Piecewise Polynomial Harmonic, since it uses piecewise polynomials defined by means of an adaption based on the ...

Multilayer-HySEA model validation for landslide-generated tsunamis – Part 2: Granular slides [PDF]
The final aim of the present work is to propose a NTHMP-benchmarked numerical tool for landslide-generated tsunami hazard assessment. To achieve this, the novel Multilayer-HySEA model is validated using laboratory experiment data for landslide-generated ...
