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 ...
Multi-Criteria Decision Making and Numerical Optimization Approaches for Optimizing Water Loss Management Strategies in Water Distribution System A case of Urban Water Supply and Sanitation Authorities in Tanzania
(Modern education and computer science press, 2019-11)
Water loss in water distribution systems (WDS) is a serious problem in Tanzania and the third world countries
at large. A lot of water is lost on its way before reaching the consumers. This causes a shortage of water ...
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 ...
Web-based Application Tool for Recommendation of Open Source Software for Higher Learning Institution in Tanzania
(Modern Education and Computer Science Press, 2019-02)
Open Source Software (OSS) provide a number of advantages to Higher Learning Institutions (HLIs) in developing countries, such as Tanzania. This is because they are freely available, free to make copies and free to distribute. ...
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 ...
Classroom ICT integration in Tanzania: Opportunities and challenges from the perspectives of TPACK and SAMR models
(International Journal of Education and Development using Information and Communication Technology (IJEDICT), 2016)
With the education systems demand of contemporary technologies, teacher trainees should be
imparted with competencies and skills to integrate information and communication technology
(ICT) into their future teaching and ...
Towards a framework for accessing agricultural market information
(The Electronic Journal of Information Systems in Developing Countries, 2015)
Management, development partners, private sector and NGOs are accustomed to ensure enabling
infrastructure is provided. Access to markets requires good transport and low transaction cost
accompanied with recent market ...

(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 ...
