(Makerere University, 2022-04-05)
Digital Terrestrial Television (DTTV) broadcasting transmitters use radiofrequency electromagnetic
waves to broadcast television signals to television viewers in an area of interest.
The strength of a received television ...
Mathematical Modelling of Harvesting of a Stage and Size - Structured Fish Population: the Case of African Catfish and Nile Tilapia
(Makerere University, 2023-01)
Over fishing has a great impact on the fish population because it results into decrease of fish stock and extinction of fish species. Consumer-resource systems with harvesting, in which African catfish (Glarias~gariepinus) ...
Performance of selected natural dyes in dye sensitized solar cells
(Makerere University, 2022)
Organic dyes have the potential for use as sensitizers in dye sensitized solar cells (DSSC). To this end, the performance of anthocyanins in DSSC has been investigated. Anthocyanins were extracted from fresh flowers of ...
Prediction of daily global solar radiation on a horizontal surface in Uganda using artificial neural networks.
(Makerere University, 2022-02-03)
In this research a five parameter artificial neural network model was developed to predict daily global solar radiation on a horizontal surface using input variables that include; sunshine hours, maximum temperature, minimum ...
Measurement and modeling of residual stress in porcelain tiles formulated from different quartz particle sizes in Uganda
(Makerere University, 2021-06)
Quartz plays a significant role in physicomechanical properties of tiles, because it is the most abundant crystalline phase present in a fired product. The use of quartz particle size that exceeds 32 µm can be detrimental ...

(Makerere University, 2022-09-20)
This study determined sorption kinetics and sorption equilibrium of cypermethrin on soil samples from sugar cane plantations in Kakira and Lugazi, and an oil palm tree growing area (Kalangala) in Uganda. Cypermethrin ...
Design of a water purification technology for the removal of Iron, Manganese, and Escherichia coli from ground water supply of Oruchinga Refugee Settlement Communities
(Makerere University, 2022)
The present study investigated the levels of iron, manganese, and E. coli in the boreholes and shallow wells waters of the Oruchinga valley refugee camp. A multi-stage filter technology was designed for the removal of total ...
Development of a thermal energy storage system Integrated with a cooking unit.
(Makerere University, 2022-07-19)
The application of thermal energy storage technology in domestic cooking is a modern
clean method where heat energy is stored in sensible or latent form. To extract the stored
heat energy, specialized heat transfer ...
