On a Retarded Nonlocal Ordinary Differential System with Discrete Diffusion Modeling Life Tables

open access: yesMathematics, 2021
In this paper, we consider a system of ordinary differential equations with non-local discrete diffusion and finite delay and with either a finite or an infinite number of equations.

Improved third-order WENO-N3 scheme and its application in simulating explosion load in confined space

open access: yesZhongguo Jianchuan Yanjiu, 2018
[Objectives] In this paper, an improved third-order WENO scheme named ‘WENO-N+3’ is constructed by adding a suitable term to the weights of the conventional WENO-N3 scheme.

The Role of Income Smoothing on Financial Performance Indicators

open access: yes3C Empresa. Investigación y pensamiento crítico, 2023
The primary objective of this study is to determine whether income smoothing procedures have an impact on the financial performance of return on assets (ROA) and return on equity (ROE). Data for this study came from a sample of banks that are listed on the Iraq Stock Exchange.

Independence and upper extremity functioning after spinal cord injury: a cross-sectional study

open access: yesScientific Reports, 2023
Upper extremity functioning is important for achieving independence in activities of daily living (ADL). A better understanding of relationships between different aspects of independence in ADL after spinal cord injury (SCI) and upper extremity ...

Simple smoothness indicator WENO-Z scheme for hyperbolic conservation laws [PDF]

open access: yesApplied Numerical Mathematics, 2019
The advantage of WENO-JS5 scheme [ J. Comput. Phys. 1996] over the WENO-LOC scheme [J. Comput. Phys.1994] is that the WENO-LOC nonlinear weights do not achieve the desired order of convergence in smooth monotone regions and at critical points.

The Train-Bridge Coupled Vibration Analysis of a Long-Span Prestressed Concrete Continuous Beam Bridge under Creep Deformation Effect

open access: yesApplied Sciences, 2022
The track smoothness of high-speed railroads is severely limited to ensure train performance. The concrete continuous girder bridge is deformed to influence the smoothness of the bridge decks and track caused by creep bulge.
