High-Order Approximation to Generalized Caputo Derivatives and Generalized Fractional Advection–Diffusion Equations

open access: yesMathematics, 2023
In this article, a high-order time-stepping scheme based on the cubic interpolation formula is considered to approximate the generalized Caputo fractional derivative (GCFD).

Homogeneous difference schemes [PDF]

open access: yesUSSR Computational Mathematics and Mathematical Physics, 1962
Abstract Homogeneous difference schemes, suitable for transforming differential equations whose coefficients belong to certain classes of function into difference equations, are defined and discussed. The main points which arise are, first, whether the solution of the resulting difference equation converges to that of the original differential ...

A 5th order monotonicity-preserving upwind compact difference scheme

open access: yes, 2011
Based on an upwind compact difference scheme and the idea of monotonicity-preserving, a 5th order monotonicity-preserving upwind compact difference scheme (m-UCD5) is proposed.

On the accuracy of difference scheme for Navier-Stokes equations

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
The article presents a study of difference schemes in time, which accuracy can be arbitrarily high. We present difference schemes in time for solving the Navier-Stokes equations, where series expansions are used to find the singularities of solutions of ...

Application of the Method of Summation Identities in Solving a Boundary-Value Problem for the Lame Equations [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2016
A boundary-value problem on an interval for a one-dimensional system of the Lame equations corresponding to a physical problem of propagation of an elastic wave through the gradient layer is considered. In this case, the coefficients of the equations are

The modeling of LED's disposition

open access: yesLietuvos Matematikos Rinkinys, 2004
The goal of this work is to construct the scheme of constructing light  – emitting diodes system. The mathematical model was written for a light-emitting diodes lamp. The finite difference technique was used for the discretization of mathematical model.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

A three-point combined compact difference scheme [PDF]

open access: yes, 1998
A new three-point combined compact difference (CCD) scheme is developed for numerical models. The major features of the CCD scheme are: three point, implicit, sixth-order accuracy, and inclusion of boundary values. Due to its combination of the first and
