Durability Properties of Ambient-Cured Metakaolin Stabilized Compressed Earth Blocks
Edmond Didier Medongou Tejiogho*, Isaac Sanewu, Christopher Kanali and François Ngapgue
This study assessed the durability of compressed earth blocks (CEBs) stabilized with 0-19% metakaolin (CEB_MKX) and cured at ambient temperature (26 ± 0.2 °C) for 28 and 180 days. Materials were characterized mineralogically, chemically, mechanically, and physically. Metakaolin was produced by calcining kaolin at 700 °C for 3h and activated with 12M NaOH. The optimum content was 11%, in accordance
Dual-Mode Smart Waste Bin with Sensor-Based Sorting and Waste Compacting for Manual and Automatic Operation
S.A. Nchor*, A. Amankwaa F. A. Nabila, B. Amponsah, J. Agyapong
This paper presents the design and implementation of a solar-powered, dual-mode smart waste management system capable of detecting, classifying, and compacting four categories of solid waste: metal, plastic, wet waste, and paper. The system employs inductive, capacitive, moisture, and ultrasonic sensors to achieve detection accuracies of 89%, 90%, 91%, and 92%, respectively. Integrated with a GSM-
Adaptive Irrigation System Based on Evapotranspiration and Soil Moisture Sensing for Precision Agriculture
Martin Ashaba, Sollomy Ainomujuni, Andrew Tinkasiimire
Agriculture in Uganda faces mounting pressures from escalating food demand, climate variability, and declining freshwater availability, with irrigation alone accounting for over 80% of total freshwater withdrawals. To address the limitations of conventional evapotranspiration (ET) controllers—which often depend on expensive meteorological instrumentation—this study proposes a cost-effective, senso
Engineering the Future: Mentorship for Young Students and Graduates in Career, Personal, and Professional Progression in Africa: Case Study Kenya
Annette Ingaiza*, Paul Ochola
Engineering is fundamental to sustainable development, innovation, and economic growth in Africa. However, the continent continues to face significant challenges in cultivating the next generation of engineers, particularly among youth. In Kenya, many students lack exposure to engineering practice, guidance in career planning, and mentorship from industry professionals. These gaps contribute to lo
Analyzing Distribution Network Performance Gaps and Modernization Challenges in Uganda’s Electricity Sector: A Case Study of Kampala West Region
Hassan Ssekaayi, Judith Taaka, Milton Edimu, Jane Namaganda Kiyimba
This paper analyzes Uganda’s electricity distribution network performance gaps and modernization challenges using Kampala West region’s Kitala feeder as a case study. Industry-standard reliability indices including System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), Customer Average Interruption Duration Index (CAIDI), modernization maturity ass
Unlocking Clean Aviation in Africa: Challenges to localising Hydrogen Aviation Propulsion in South Africa
Purusha Naidoo*, Kevin Jamison
The global aviation industry has adopted ICAO’s Long-Term Aspirational Goal (LTAG) to achieve net-zero emissions by 2050. Hydrogen fuel cell propulsion is recognised as a key enabler of zero-emission aviation. While South Africa has strong potential for green hydrogen production due to its renewable energy resources, the country does have challenges in localising hydrogen aviation propulsion techn
