Fourth-Order Difference Scheme and a Matrix Transform Approach for Solving Fractional PDEs

open access: yesMathematics, 2023
Proposing a matrix transform method to solve a fractional partial differential equation is the main aim of this paper. The main model can be transferred to a partial-integro differential equation (PIDE) with a weakly singular kernel.

The hyperbolic equation with fractional derivative in modelling the polymer concrete behaviour under constant load [PDF]

open access: yesE3S Web of Conferences, 2023
The paper considers an inhomogeneous partial differential equation of hyperbolic type containing both second order partial derivatives and fractional derivatives of an order lower than the second order on the spatial variable.

Validity of Galerkin Method at Beam’s Nonlinear Vibrations of the Single Mode with the Initial Curvature

open access: yesBuildings, 2023
A common strategy for studying the nonlinear vibrations of beams is to discretize the nonlinear partial differential equation into a nonlinear ordinary differential equation or equations through the Galerkin method.

Interpretation of Frenkel’s theory of sintering considering evolution of activated pores: II. Model and reliability [PDF]

open access: yesScience of Sintering, 2015
Frenkel's liquid-phase sintering mechanism has essential influence on the sintering of materials, however, by which only the initial 10% during isothermal sintering can be well explained. To overcome this shortage, Nikolić et al.

On Partial Complete Controllability of Semilinear Systems

open access: yesAbstract and Applied Analysis, 2013
Many control systems can be written as a first-order differential equation if the state space enlarged. Therefore, general conditions on controllability, stated for the first-order differential equations, are too strong for these systems.

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).

NONLINEAR EQUATION WITH THE THIRD ORDER SCATTERING OPERATOR

open access: yesНаука. Инновации. Технологии, 2022
Introduction: most of the differential equations associated with soliton mathematics are obtained using the Lax operator equation or the zero-curvature equation, which are the compatibility condition for a pair of linear differential systems. The case in
