A reference machine learning model for prediction of cholera epidemics based-on seasonal weather changes linkages in Tanzania
(NM-AIST, 2020-08)The Cholera epidemic remains a public threat throughout history, affecting vulnerable populations living with unreliable water and sub-standard sanitary conditions. Studies have observed that the occurrence of cholera ... -
Machine learning models for predicting decisions to be made by small scale dairy farmers in Eastern Africa
(NM-AIST, 2020-03)In dairy, lack of decision support tools for identifying farmers' needs and demands have caused many programs, strategies, and projects to fail. This has led to the inefficient and fragmented allocation of scarce development ... -
Use of agent – based models in characterizing farm types and evolvement in smallholder dairy systems
(NM-AIST, 2020-04)The ever-increasing demand for milk and dairy products has attracted research interventions on how milk yield can be increased for the context of smallholder farmers. While bearing significant contribution on milk ... -
A secure and interoperable blockchain-based information sharing system for healthcare providers in developing countries
(NM-AIST, 2020-03)Systems in the health sector are very crucial for human life and they should be efficient, reliable and secure. Unfortunately, electronic health record (EHR) systems do not work effectively when managing multi-institutional ... -
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 ... -
