type: item
description: Power distribution equipment systems (PDES) play a critical role in the efficient management of electrical energy supply in Tanzania. A time-series forecasting model was developed, incorporating historical data on the installation and usage patterns of PDES. The empirical findings suggest a steady increase in the proportion of households adopting PDES from 20% in to an estimated 35% by with a margin of error of ±5%. The time-series model accurately predicted the adoption rates, providing insights for policy makers and investors. Investment strategies should be tailored towards regions where PDES adoption is expected to grow rapidly based on the forecasted data.

Methodological Evaluation of Municipal Infrastructure Assets Systems in Senegal
type: item
description: Municipal infrastructure assets systems are crucial for urban development in Senegal, yet their cost-effectiveness remains underexplored. We employed a multilevel regression model with robust standard errors to analyse data from various municipalities across Senegal, accounting for both individual and contextual effects. Our multilevel regression analysis revealed that the level of investment per capita in municipal infrastructure assets significantly influences their cost-effectiveness. Specifically, an increase in investment by $100 per capita led to a 5% improvement in cost-effectiveness, with a confidence interval for this effect at (3%, 7%). The findings suggest that targeted investments in municipal infrastructure can lead to more efficient and effective asset management systems. Policy makers should prioritise investment strategies based on the analysis of local municipal data to optimise resource allocation and improve service delivery. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Structural Integrity Assessment of Aging Infrastructure in Uganda
type: item
description: The structural integrity of aging infrastructure in Uganda is a critical issue, particularly in bridges and buildings that are approaching or have surpassed their design lifespans. Non-destructive evaluation (NDE) methods such as ultrasonic thickness gauges and eddy current probes were employed to assess the condition of steel reinforcement bars in selected bridges. A Bayesian hierarchical model was used to estimate the probability of failure based on NDE data, accounting for uncertainties associated with material properties. Ultrasonic testing revealed varying degrees of corrosion around rebar in several structures, with a proportion exceeding 20% in some critical components. The non-destructive evaluation methods employed provided reliable estimates of structural integrity but were subject to measurement uncertainties due to material variability and environmental conditions. Immediate repairs are recommended for bridges identified as having rebar corrosion levels over 20%, with a focus on strengthening vulnerable areas using proven repair techniques. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Methodological Evaluation of Multilevel Regression Analysis in Assessing Water Treatment Facility Adoption Rates in Uganda
type: item
description: Water treatment facilities play a crucial role in improving water quality and public health outcomes in Uganda. However, adoption rates have been inconsistent across different regions. A multilevel logistic regression model was employed to analyse data from a survey conducted in three districts, incorporating both individual and district-level variables. The multilevel model revealed that infrastructure availability (20% increase) and community education programmes (15% increase) were significant predictors of adoption rates. Multilevel regression analysis provided a robust framework for understanding the complex factors affecting water treatment facility adoption in Uganda. Future studies should consider longitudinal data to better track changes over time and incorporate additional socioeconomic variables. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Bayesian Hierarchical Model for System Reliability Assessment of Transport Maintenance Depots in Ethiopia
type: item
description: This study focuses on evaluating the reliability of transport maintenance depots in Ethiopia, a critical infrastructure for ensuring smooth transportation and logistics operations. A Bayesian hierarchical model will be employed to analyse data collected from Ethiopian transport maintenance depots. This approach allows for the estimation of system reliability at both depot level and national scale, accounting for variability across different depots and sectors. The analysis revealed significant variations in system reliability among depots, with some showing a 20% higher likelihood of failure compared to others under similar conditions. This study provides evidence-based insights into the maintenance depot systems' performance, highlighting variability and potential areas for improvement. Based on the findings, targeted interventions such as improved training programmes and enhanced maintenance protocols are recommended for depots with higher failure rates. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Time-Series Forecasting Model Evaluation of Water Treatment Facilities in Senegal
type: item
description: Water treatment facilities in Senegal are critical for ensuring safe drinking water and sanitation services across the country. However, their effectiveness varies over time, necessitating a systematic evaluation to optimise resource allocation. A time-series forecasting model was developed using historical data from water treatment plants in Senegal, including parameters such as inflow volume, treatment process efficiency, and operational costs. Robust standard errors were used for the statistical analysis to account for uncertainties in input variables. The forecast model identified a significant decline in effluent quality over time, which correlated with increased operational costs despite consistent funding levels. This trend suggests that current facilities may not be sustainable without substantial upgrades or alternative strategies. This study provides a novel method for evaluating the cost-effectiveness of water treatment facilities by integrating historical data and forecasting models, offering insights into potential improvements in Senegal’s water infrastructure. Based on the findings, it is recommended that policymakers consider implementing preventive maintenance programmes to mitigate future declines in effluent quality and explore partnerships with private sector entities for more efficient service delivery. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Geotechnical Engineering in Foundation Design for Expansive Soils in Sudan
type: item
description: Geotechnical engineering plays a crucial role in foundation design for expansive soils, which are prevalent in arid regions like Sudan. These soils experience significant volume changes due to moisture variations, posing challenges for construction projects. The study employed a mixed-method approach, combining laboratory tests with field observations to validate design calculations based on empirical data collected during construction phases. A statistical model was used to predict soil behaviour under varying moisture conditions. Field observations showed that the designed foundations consistently performed within expected variability margins, indicating successful adaptation of geotechnical principles to local conditions. Laboratory results confirmed predicted soil expansion rates with a confidence interval of ±5%. The study supports the feasibility of applying geotechnical engineering in foundation design for expansive soils in Sudan's context from an Ethiopian standpoint. Given the successful application, it is recommended that similar designs be considered for future projects involving expansive soil foundations in Sudan. Further research should focus on long-term performance and potential improvements to existing models. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Designing Economical Irrigation Architectures for Drought Mitigation in Mali's Agricultural Sectors
type: item
description: Agricultural sectors in Mali are frequently affected by droughts, leading to significant yield losses and economic instability. A mixed-method approach was employed, combining field surveys, expert consultations, and a cost-benefit analysis to evaluate various irrigation system designs. The findings indicate that drip irrigation systems are the most economical option in sandy soils with limited water supply (40% of surveyed areas), while flood irrigation is more suitable for clay soils with higher water retention capacity (60% of surveyed areas). Low-cost irrigation systems, particularly drip and flood irrigation, can be effectively implemented to improve agricultural productivity and resilience in drought-prone regions. Policy recommendations include subsidizing the installation of low-cost irrigation infrastructure and providing training on sustainable water management practices.

Methodological Evaluation of Transport Maintenance Depot Systems in Nigeria Using Difference-in-Differences for System Reliability Assessment
type: item
description: Transport maintenance depots (TMDs) in Nigeria are critical infrastructure for ensuring road safety and vehicle reliability. However, their operational effectiveness varies significantly across different regions. A DID analysis was employed to assess changes in vehicle maintenance outcomes before and after the implementation of new operational procedures at selected depots. The study utilised data from 10 randomly chosen TMDs over a two-year period. The results indicate that there is a statistically significant improvement (p < 0.05) in vehicle reliability post-intervention, with an estimated increase of 25% in the proportion of vehicles meeting maintenance standards. This study provides empirical evidence supporting the effectiveness of DID methodology for evaluating system reliability in TMDs and offers a robust framework for future research and policy development. Transport authorities should consider replicating this approach across other depots to enhance overall vehicle safety and efficiency in Nigeria.

description: In Botswana's mining sector, environmental monitoring is crucial for sustainable operations. However, current systems are often inadequate and prone to errors. The methodology involved the design and deployment of IoT systems equipped with sensors, data collection, and analysis using statistical models. Data collected from the sensors showed a significant correlation ($R^2 = 0.95$) between temperature and humidity levels in mine pits, indicating high reliability of monitoring systems. The developed IoT systems successfully monitored environmental conditions in mining sites with minimal human intervention. Further research should focus on integrating AI for predictive maintenance and expanding the system to other mine sites. Environmental Monitoring, IoT Systems, Mining Sites, Botswana

Time-Series Forecasting Model Evaluation for Risk Reduction in Power-Distribution Equipment Systems in Uganda
type: item
description: Power distribution equipment systems in Uganda face challenges related to maintenance and reliability, leading to potential disruptions in power supply. A time-series forecasting model was developed using historical data from power distribution systems. Robust standard errors were calculated to assess the uncertainty in predictions. The model demonstrated a correlation coefficient of $R^2 = 0.85$ between predicted and actual maintenance needs, indicating a significant predictive capability for risk reduction. While the model showed promising results, further validation with real-world data is required to confirm its efficacy in reducing equipment failures and enhancing system reliability. Further research should be conducted to validate the model's performance using actual maintenance records from power distribution systems across different regions of Uganda.
