(Kyambogo University (un published work), 2019-11)Government has put in place plans for road development and maintenance and has improved on its budget allocations, in order to boost tourism, agriculture and mining, among others. However, road maintenance remains a challenge ... -
Development of a mathematical model for integration of robots in a steel manufacturing plant
(Kyambogo University, 2021-07)The use of computer-controlled robots is increasingly picking up in today’s manufacturing industries. Industrial robot application in manufacturing industries allows for improved flexibility and configurability required ... -
Does training improve sanitary inspection answer agreement between inspectors? Quantitative evidence from the Mukono district, Uganda
(MDPI, 2020-10-10)Sanitary inspections (SIs) are checklists of questions used for achieving/maintaining the safety of drinking-water supplies by identifying observable actual and potential sources and pathways of contamination. Despite the ... -
Dynamically dimensioned search embedded with piecewise opposition-based learning for global optimization
(2019-05-26)Dynamically dimensioned search (DDS) is a well-known optimization algorithm in the field of single solution-based heuristic global search algorithms. Its successful application in the calibration of watershed environmental ... -
Effect of banana fibers on the mechanical and microstructural properties of concrete
(Kyambogo university (unpublished work), 2021-08)This research presents an experimental study on the "Effect of Banana fibres on the mechanical and microstructural properties of concrete". Concrete being a quasi-brittle material, exhibits limited ability to restrict ... -
Effect of filler and binder contents on air voids in hot-mix asphalt for road pavement construction
(Kyambogo University, 2021-08)Filler and binder make up a small proportion of bituminous mixtures, hence they are considered as important ingredients of mixtures. Sometimes due to equipment error during production, some mixtures retain extra or a reduced ... -
Effects of power interruptions on quality and production in a galvanizing plant Case study: roofings rolling mills ltd, Namanve, Kampala
(Kyambogo University, 2019-11)Steel is the most used engineering material industries. In Uganda, Roofings Rolling Mills Ltd (RRM) is the largest steel manufacturer; with mega industrial undertakings which is in line with national economic development ... -
Enhancing a sustainable safe water supply for rural communities of Mabungo parish, Kisoro district
(Kyambogo University (un published work), 2019-07)Access to safe water is still a challenge in Africa, the biggest population that suffers the challenge being from sub-Saharan African countries where Uganda is part. The major cause of limited water access is that 85% of ... -
An evaluation of rural road management as a driver of economic development: a case study of Kabarole district
(Kyambogo University, 2021-08)Rural roads form the largest part of the road network and the main form of access to the rural communities. The poor state of rural road networks not only affects transport of goods and services but also the economic growth. ... -
Field-based methods for measuring greenhouse gases emissions from on-site sanitation systems: A systematic review of published literature
(Heliyon, 2023-04)On-site sanitation systems (OSS) are a source of greenhouse gas (GHG) emissions. Although ef- forts have been made recently to measure and quantify emissions from septic tanks using various field-based methods, the vast ... -
Graphical-statistical method to explore variability of hydrological time series
(Hydrology Research, 2021-02)Due to increasing concern on developing measures for predictive adaptation to climate change impacts on hydrology, several studies have tended to be conducted on trends in climatic data. Conventionally, trend analysis ... -
Hydrodynamic modelling of floods and estimating socio‑economic impacts of floods in Ugandan River Malaba sub‑catchment
(Earth Systems and Environment : Springer link, 2022-01-01)River Malaba sub-catchment tends to experience dramatic flooding events, with several socio-economic impacts to the nearby communities, such as loss of lives and destructions of physical infrastructure. Analysis of ... -
A hydrological model skill score and revised R-squared
(Hydrology Research, 2022-01-01)Despite the advances in methods of statistical and mathematical modeling, there is considerable lack of focus on improving how to judge models’quality. Coefficient of determination (R2) is arguably the most widely applied ... -
Hydrological model supported by a step-wise calibration against sub-flows and validation of extreme flow events
(MDPI, 2019-01-31)Most hydrological models have fixed structures and their calibrations are typified by a conventional approach in which the overall water balance closure is considered (without a step-wise focus on sub-flows’ variation). ... -
