On stable numerical differentiation [PDF]
Mathematics of Computation, 2001 A new approach to the construction of finite-difference methods is presented. It is shown how the multi-point differentiators can generate regularizing algorithms with a stepsize h h

Numerical Derivative Using the Piecewise Uniform Mesh [PDF]
Kirkuk Journal of Science, 2018 In this paper, a technique of a piecewise-uniform meshes formed on an improvement finite difference algorithm for finding derivatives of functions. The purpose was to overcome difficulties which face numerical derivatives of functions with stiff formula,

Minimal numerical differentiation formulas [PDF]
Numerische Mathematik, 2018 We investigate numerical differentiation formulas on irregular centers in two or more variables that are exact for polynomials of a given order and minimize an absolute seminorm of the weight vector. Error bounds are given in terms of a growth function that carries the information about the geometry of the centers.

Method for Determining the Sea Waves Curvature Using Wave Buoys Conventional Shape
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. Modern wave buoys due to their design make it possible to determine a directional wave spectrum using five coefficients of the Fourier series. However, up to nine members of the series can be determined from wave surface measurements.
