A Richardson’s Extrapolation Spreadsheet Calculator for Numerical Differentiation [PDF]
Spreadsheets in Education, 2013 Even though approximating the definite differentiation by Richardson’s extrapolation method is straight forward, but its repetitive calculations are quite boring. Hence, there is a need to develop a suitable tool in teaching and learning for this method.

Numerical Differentiation and Integration through Aitken-Neville Schemes
International Journal of Analysis and Applications, 2013 Some new formulas are given to approximate higher order derivatives and integrals through Aitken-Neville iterative schemes for arbitrary spaced grids. An algorithm is given in MATLAB for numerical differentiation. Also, numerical examples are provided to

Tracking autophagy during proliferation and differentiation of Trypanosoma brucei [PDF]
, 2014 Autophagy is a lysosome-dependent degradation mechanism that sequesters target cargo into autophagosomal vesicles. The Trypanosoma brucei genome contains apparent orthologues of several autophagy-related proteins including an ATG8 family. These ubiquitin-

A Two-Stage Method for Parameter Identification of a Nonlinear System in a Microbial Batch Process
Applied Sciences, 2019 This paper deals with the parameter identification of a microbial batch process of glycerol to 1,3-propanediol (1,3-PD). We first present a parameter identification model for the excess kinetics of a microbial batch process of glycerol to 1,3-PD.

An Adaptive Method for Numerical Differentiation of Difficult-to-Compute Functions [PDF]
Journal of Mechanical Engineering, 2021 An adaptive approach to the numerical differentiation of difficult-to-compute functions is considered. Complex dependencies, which are the result of multiple superpositions of functions or the product of various algorithmic processes, are knowingly ...
