On Conservative Finite-Difference Schemes for the One-Dimensional MHD Equations in Cylindrical Geometry Possessing Additional Conservation Laws

Proceedings of the International Conference Modern Achievements in Symmetries of Differential Equations (Symmetry 2022), 2022
Based on recent results in the construction of conservative finite-difference schemes, a new scheme for one-dimensional isentropic flows of polytropic gas in cylindrical geometry in the presence of a radial magnetic field is presented. The proposed scheme adds to the list of recently constructed schemes, and completes the consideration of conservative ...

[Additive aboveground biomass equations based on different predictors for natural Tilia Linn].

Ying yong sheng tai xue bao = The journal of applied ecology, 2019
Biomass is a basic quantitative character of forest ecosystem. Biomass data are foundation of researching many forestry and ecology problems. Accurate quantification of tree biomass is critical and essential for calculating carbon storage, as well as for studying climate change, forest health, forest productivity, nutrient cycling, etc.

H-U-R Stability Results of Mixed-Type Additive-Quadratic Functional Equation in Fuzzy β-Normed Spaces by Two Different Approaches

2021
Fuzzy set theory is a powerful hand set for modelling uncertainty and vagueness in various problems arising in the field of science and engineering. It has also very useful applications in various fields. Also, stability problem of a functional equation was first posed by Ulam which was answered by Hyers and then generalized by Aokiand Rassias for ...

Rapid Modeling of Photopolymerization in Projection Two-Photon Lithography via an Operator Splitting Finite Difference Method

Journal of Micro and Nano-Manufacturing
Two-photon lithography (TPL) is an attractive technique for nanoscale additive manufacturing of functional 3D structures due to its ability to print sub-diffraction features with light.

Stochastic Formulation of the General Differential Difference Equation for Addition-Growth Kinetic Processes—Example of Anionic Polymerization

Journal of Macromolecular Science: Part A - Chemistry, 1969
Abstract In an effort to lend some insight into the probabilistic nature of step-growth kinetic processes, the differential rate expression for anionic polymerization with one rate constant is derived from stochastic theory.

An estimate of the “shade” of additional boundary conditions for systems of difference equations with oblique characteristics of constant sign

USSR Computational Mathematics and Mathematical Physics, 1989
Estimates are established for the width of the “e-shadow”—the region outside which the solution of given difference boundary-value problem differs from the solution of the corresponding left-hand difference boundary-value problem by a quantity O(h q+e ) where q is the order of approximation of the left-hand difference boundary-value problem.
