Short-term load forecasting in a hybrid microgrid: a case study in Tanzania
(Journal of Electrical Systems, 2019)Most emerging countries such as Tanzania are promoting rural electrification through installation of microgrids. This paper proposes an approach for short-term day-ahead load forecast in rural hybrid microgrids in emerging ... -
Simulation and Experimental Performance Analysis of Portable Locally-Made Solar-Powered Cooler for Vaccine Storage
(Trans Tech Publications Ltd, 2025-02)Poor storage conditions, particularly exposure to extreme temperatures, can significantly compromise vaccine efficacy, making them ineffective or harmful. This highlights the urgent need for adequate storage infrastructure ... -
Simulation and optimisation of the pyrolysis of rice husk: Preliminary assessment for gasification applications
(Elsevier B.V., 2020-09)Thermochemical conversion of biomass into useful products is a promising route to harness biofuels. This process is clean, renewable and can reduce the use of fossil fuel. In this study, SuperPro Designer (SPD) software ... -
Simulation and performance analysis of municipal solid waste gasification in a novel hybrid fixed bed gasifier using Aspen plus
(Taylor & Francis Online, 2020-08-27)Thermochemical conversion technologies (incineration, gasification, and pyrolysis) have emerged as potential technologies for municipal solid waste management. Incineration is the most common thermo-chemical technology ... -
Small Estuarine and Non-Estuarine Mangrove Ecosystems of Tanzania: Overlooked Coastal Habitats?
