Mathematical Model for Optimal Control of Soil-Transmitted Helminth Infection
(Hindawi, 2020-08-01)
In this paper, we study the dynamics of soil-transmitted helminth infection. We formulate and analyse a deterministic compartmental model using nonlinear differential equations. The basic reproduction number is obtained ...
Identification of the Time-Dependent Point Source in a System of two Coupled Two Dimension Diffusion-Advection-Reaction Equations: Application to Groundwater Pollution Source Identification
(Global Journal of Pure and Applied Mathematics, 2020)
This paper addresses the inverse source problem in a system of two-dimension
advection-dispersion reaction equation with an emphasis on groundwater pollution
source identification. We develop an inverse source problem ...
MHD Arterial Blood Flow and Mass Transfer under the Presence of Stenosis, Body Acceleration and Chemical Reaction: A Case of Magnetic Therapy
(Journal of Mathematics and Informatics, 2020-02-17)
A mathematical model has been developed and used to study pulsatile blood
flow and mass transfer through a stenosed artery in the presence of body acceleration and
magnetic fields. An explicit Finite Difference Method ...
Identification of multiple unknown point sources occurring in the 2D transport equation: application to groundwater pollution source identification
(Journal of Mathematical and Computational Science, 2020-02-29)
Water loss in the water distribution systems (WDS) is a challenge to many
water authorities in the world but the problem is crucial in the less developed countries.
The effect of water losses in the WDS includes the ...
Optimisation of Water Loss Management Strategies: Multi-Criteria Decision Analysis Approaches
(Journal of Mathematics and Informatics, 2020-02-29)
Water loss in the water distribution systems (WDS) is a challenge to many
water authorities in the world but the problem is crucial in the less developed countries.
The effect of water losses in the WDS includes the ...
Computational Fluid Dynamics of Manhole Overflow Due to Storm-water Inflow
(Journal of Mathematics and Informatics, 2020-01-20)
In this study, the storm water overflow on manholes is numerically solved. To
produce a real representation of storm overflow, the Navier-Stokes equations were used.
Turbulence was modelled using the standard k-epsilon ...
The Challenges of Adopting M-Learning Assistive Technologies for Visually Impaired Learners in Higher Learning Institution in Tanzania
(International Journal of Emerging Technologies in Learning (iJET), 2020)
In the past decades, the world has experienced major changes in the advancement of learning technologies which has enabled learners to engage in their learning activities anywhere. The penetration of mobile phone internet ...
An Application of Computational Fluid Dynamics to Optimize Municipal Sewage Networks; A Case of Tororo Municipality, Eastern Uganda.
(Journal of Advances in Mathematics, 2020-01)
Two-phase pipe flow is a common occurrence in many industrial applications such as sewage, water, oil, and
gas transportation. Accurate prediction of liquid velocity, holdup and pressure drop is of vast importance to
ensure ...
Dividend Maximization Under a Set Ruin Probability Target in the Presence of Proportional and Excess-of-loss Reinsurance
(Applications and Applied Mathematics, 2020-06)
We study dividend maximization with set ruin probability targets for an insurance company whose
surplus is modelled by a diffusion perturbed classical risk process. The company is permitted to
enter into proportional or ...
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters
(Springer Nature, 2020-06-11)
Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ...
