A Mathematical Model for the Co-infection Dynamics of Pneumocystis Pneumonia and HIV/AIDS with Treatment
(Science Journal of Applied Mathematics and Statistics, 2023)The control of opportunistic infections among HIV infected individuals should be one of the major public health concerns in reducing mortality rate of individuals living with HIV/AIDS. In this study a deterministic ... -
A Mathematical Model for the Dynamics of Onchocerciasis With Vector Control and Mass Drug Administration
(Journal of Applied Mathematics, 2024)In this paper, we investigate the transmission dynamics of onchocerciasis with asymptomatic infected humans using a mathematical model. The model incorporates interventions for treatment and vector control to evaluate the ... -
Mathematical Modelling of Tuberculosis and Hepatitis C Coinfection Dynamics with No Intervention
(Journal of Mathematics, 2024)In this study, a deterministic tuberculosis (TB)-hepatitis C (HCV) coinfection mathematical model with no intervention is analysed purposely to examine the dynamics of TB HCV coinfection so as to find conditions for reducing ... -
Assessing the Impact of E-Learning on Learners Mathematics Performance in Nakivale Refugee Settlement, Uganda
(Journal of Applied Sciences, Information, and Computing, 2021)This study investigated the impact of e-learning on learners’ academic performance in mathematics in Nakivale refugee settlement, Uganda. A causal-comparative research design was used to measure the effect of implemented ... -
A mathematical model for treatment of bovine brucellosis in cattle population
(Journal of Mathematical Modeling, 2017)Brucellosis is an infectious bacterial zoonosis of public health and economic significance. In this paper, a mathematical model describing the propagation of bovine brucellosis within cattle population is formulated. Model ... -
Application of the Boundary Element Method Using Time Discretization to the Advection-Convection Equation
(Journal of Applied & Computational Mathematics, 2018)The boundary element method is a numerical computational method of solving partial differential equations which have been formulated as integral equations. It can be applied in many areas of engineering and science including ... -
Numerical Solution to Two-point Boundary Value Problems with Neumann Boundary Conditions using Galerkin Finite Element Method
(2023)In this study, Galerkin finite element method (FEM) has been developed to approximate the solution of both second-order linear with constant and non-constant coefficients, and nonlinear second-order two-point BVP of ordinary ... -
An Optimal Control for Ebola Virus Disease with a Convex Incidence Rate: Imputing from the Outbreak in Uganda.
(Qeios, 2023)Ebola Virus disease (EVD) is an emerging and re-emerging zoonotic disease which mostly occur in Africa. Both prediction of the next EVD and controlling an ongoing outbreak remain challenging to disease prone countries. ... -
A Mathematical Model of Treatment and Vaccination Interventions of Pneumococcal Pneumonia Infection Dynamics
(Journal of Applied Mathematics, 2018)Streptococcus pneumoniae is one of the leading causes of serious morbidity and mortality worldwide, especially in young children and the elderly. In this study, a model of the spread and control of bacterial pneumonia under ... -
The fundamental solution of the one–dimensional elliptic operator and its application to solving the advection–diffusion equation
(Research gate, 2020)The advection–diffusion equation is first formulated as a boundary integral equation, suggesting the need for an appropriate fundamental solution to the elliptic operator. Once the fundamental solution is found, then a ... -
Influence of Teaching Approaches on Students’ Performance in Mathematics: A meta-analysis of Quasi-Experimental Studies in Africa
(African Journal of Educational Studies in Mathematics and Sciences, 2021)There has been poor performance in national and international mathematics assessments among African students compared to the rest of the planet. Such consistent underperformance is attributed to factors like teaching ... -
Solving the Cauchy problem for the Helmholtz equation using cubic smoothing splines
(Journal of Applied Mathematics and Computing, 2021-06-11)We consider the Cauchy problem for the Helmholtz equation defined in a rectangular domain. The Cauchy data are prescribed on a part of the boundary and the aim is to find the solution in the entire domain. The problem ... -
A Mathematical Model of Solid Waste Accumulation and Treatment with a Varying Human Population Size
(Biomath Communications, 2022)Solid waste management has continued to be an increasing challenge worldwide and the situation has become worse in urban areas of developing countries. The rapid urban population growth, mainly due to high immigration and ... -
Ratio-cum-product estimator using multiple Auxiliary attributes in two-phase sampling
(Scientific Research Publishing Inc, 2014)In this paper, we have proposed three classes of ratio-cum-product estimators for estimating population mean of study variable for two-phase sampling using multi-auxiliary attributes for full information, partial information ... -
