An assessment of semi-discrete central schemes for hyperbolic conservation laws. [PDF]
, 2003 High-resolution finite volume methods for solving systems of conservation laws have been widely embraced in research areas ranging from astrophysics to geophysics and aero-thermodynamics. These methods are typically at least second-order accurate in space and time, deliver non-oscillatory solutions in the presence of near discontinuities, e.g., shocks,

A Novel Optimized Semi-Blind Scheme for Color Image Watermarking
IEEE Access, 2020 Image watermarking is a robust solution for solving key issues like copyright protection and proof of ownership of digital data. Existing schemes of image watermarking mostly used grayscale or binary images as embedded watermarks, while only a few ...

The Müntz spectral element method for the numerical solutions of regularized long wave equation
Franklin OpenThis paper introduces new bases derived from Müntz polynomials for application in the spectral element method. Within this framework, we demonstrate that the mass and stiffness matrices exhibit matrix with three non-zero diagonals and diagonal structures,

Fourier pseudo-spectral method for the extended Fisher-Kolmogorov equation in two dimensions
Advances in Difference Equations, 2017 In the study of pattern formation in bi-stable systems, the extended Fisher-Kolmogorov (EFK) equation plays an important role. In this paper, a Fourier pseudo-spectral method for solving the EFK equation in two space dimensions is presented. Prior bounds

IEEE Access, 2019 By using semi-discrete and Takagi-Sugeno fuzzy methods, a new version of discrete analogue of stochastic fuzzy cellular neural networks is formulated, which gives a more accurate characterization for continuous-time stochastic model than that by Euler ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
