An Application of Computational Fluid Dynamics to Optimize Municipal Sewage Networks; A Case of Tororo Municipality, Eastern Uganda.
Noah, Esemu Joseph; Masanja, Verdiana Grace; Nampala, Hasifa; Lwanyaga, Joseph Ddumba; Awichi, Richard O.; Semwogerere, Twaibu (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 ... -
Application of Optimal Control Theory to Newcastle Disease Dynamics in Village Chicken by Considering Wild Birds as Reservoir of Disease Virus
Chuma, Furaha; Mwanga, Gasper Godson; Masanja, Verdiana Grace (Hindawi, 2019-03-03)In this study, an optimal control theory was applied to a nonautonomous model for Newcastle disease transmission in the village chicken population. A notable feature of this model is the inclusion of environment contamination ... -
Computational Fluid Dynamics of Manhole Overflow Due to Storm-water Inflow
Baseka, Sifa Yohana; Masanja, Verdiana Grace (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 ... -
Identification of multiple unknown point sources occurring in the 2D transport equation: application to groundwater pollution source identification
Soko, Alpha Omega; Masanja, Verdiana Grace; Abonyo, Okelo Jeconiah (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 ... -
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
Soko, Alpha Omega; Abonyo, Okelo Jeconiah; Masanja, Verdiana Grace (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 ... -
The Importance of Educating Girls and Women in Sciences
Masanja, Verdiana Grace (University of Technology of Sydney ePress, 2021-09-28)For the past decades, focus on attaining gender equality in science education has attracted a lot of attention. Governments and international community believe that girls’/women’s science education is a worthwhile ... -
Merton’s Jump Diffusion Model an Application to Stock Markets of East African Countries
Novat, Kimaro; Charles, Wilson Mahera; Masanja, Verdiana Grace (International Journal of Advances in Scientific Research and Engineering (ijasre), 2019-08-16)The stock price is characterized with a number of features which can only be captured by a best model. To investigate this the Merton’s jump diffusion model was applied to the selected stocks of three East African community ... -
MHD Arterial Blood Flow and Mass Transfer under the Presence of Stenosis, Body Acceleration and Chemical Reaction: A Case of Magnetic Therapy
Mwapinga, Annord; Mureithi, Eunice; Makungu, James; Masanja, Verdiana Grace (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 ... -
Modeling the Effect of Binding Kinetics in Spatial Drug Distribution in the Brain
Kashaju, Nelson; Kimathi, Mark; Masanja, Verdiana Grace (Hindawi, 2021-07-05)A 3-dimensional mathematical model is developed to determine the effect of drug binding kinetics on the spatial distribution of a drug within the brain. The key components, namely, transport across the blood-brain barrier ... -
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
Kadengea, Maselle Joseph; Mkandawile, Mashaka; Masanja, Verdiana Grace (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.
