Stochastic Modeling of Inflation and Interest Rates for Defined Benefit Pension Plan Projections in Ghana

Ravenhill Adjetey Laryea, Hanson Dela Quarshie, Ezekiel Nii Noye Nortey & Kwabena Doku-Amponsah · Journal of Advances in Mathematics and Computer Science · 2022

Aims/ Objectives: Pension plan administrators, employers and managers in exchange for service provided currently by employees’ pledges stated benefits in the prospective future. For this expense to be budgeted for the future, a pension cost method is used by the plan administrato...

Attractors and Numerical Simulations for a Two-Temperature Phase Transition System

Mohamed Ali Ipopa, Brice Landry Doumbe Bangola & Armel Andami Ovono · Journal of Advances in Mathematics and Computer Science · 2022

In this paper, we study a generalisation of the Caginalp phase field system obtained by considering the Fourier law as the heat conduction law and involving two temperatures. In the first section, we are interested in the existence and uniqueness of solutions. In section 2, we ad...

The Orlicz Inequality for Series of Multilinear Forms

Salih Yousuf Mohamed Salih & Shawgy Hussein · Journal of Advances in Mathematics and Computer Science · 2022

The Orlicz ( \(\ell\)2,\(\ell\)1)-mixed inequality of integers and fractional dimensions who states that, with a bit of extend, for all sequences of bilinear forms AL: \(\mathbb{K}\)n x \(\mathbb{K}\)n  \(\rightarrow\) \(\mathbb{K}\) and all positive integers n, where  \(\mathbb{...

Review of Emergency Health Care Delivery System in Nigeria

C. L. Okpalla, H. C. Inyiama, J. N. Odii, C. I. Chukwuneke & U. C. Onyemauche · Journal of Advances in Mathematics and Computer Science · 2022

The paper reviews several emergency health care delivery systems and suggests possible remedies. The health care sector is inefficient due to lack of effective management and access to patients' health records especially in an emergency. Emergency care systems are very important....

On Products of Composition and Differentiation Operators

Salih Yousuf Mohamed Salih & Shawgy Hussein · Journal of Advances in Mathematics and Computer Science · 2022

In this paper we consider products of composition and differentiation operators on the Hardy spaces. We provide a complete characterization of boundedness and compactness of these operators. M. Moradi and M. Fatehi [1] obtain the explicit condition for these operators to be Hilbe...

Hyers-Ulam-Rassias Stability of a General Septic Functional Equation

Sun-Sook Jin & Yang-Hi Lee · Journal of Advances in Mathematics and Computer Science · 2022

In this paper, we investigate the stability of the following general septic functional equation:                                                                  \(\sum_{i=0}^8{ }_8 C_i(-1)^{8-i} f(x+(i-4) y)=0\) which is a generalization of many functional equations such as the...

An Extended Six-parameter Generalised Linear Mixed Effects Model for Achievement Gaps among Public and Private Basic Schools of Ghana

Eunice Osei-Asibey, Eric Wiah Neebo & Ezekiel N. N. Nortey · Journal of Advances in Mathematics and Computer Science · 2022

The mixed generalized linear model extension has distinct advantages over generalised linear models and hierarchical linear models by reducing estimation and precision errors, and increasing power. This paper aimed at building a six parameter Generalised Mixed linear Model with f...
