    A computer vision approach towards glare mitigation and image quality enhancement in license plate recognition
    (Makerere University, 2025) Masaba, Jeremiah
    License Plate Recognition (LPR) systems play a crucial role in Intelligent Transportation Systems (ITS), facilitating automated vehicle identification for applications such as traffic monitoring, law enforcement, and toll collection. However, these systems often suffer from glare-induced distortions caused by intense light sources such as sunlight, vehicle headlights, and reflections. These distortions obscure license plate details, leading to reduced Optical Character Recognition (OCR) accuracy and compromised system reliability. This research addresses this critical challenge by developing a unified computer vision framework that integrates Autoencoders (AE) and Noise2Clean Generative Adversarial Networks (N2C-GAN) to mitigate glare and improve image quality. The study aimed to achieve four key objectives: access and utilize an existing dataset of glare-induced license plate images, image pre-processing, model implementation, and rigorous model evaluation. The proposed model demonstrated significant advances in glare mitigation, achieving a Peak Signal-to-Noise Ratio (PSNR) of 38.8 dB, a Structural Similarity Index Measure (SSIM) of 0.987, and a Visual Information Fidelity (VIF) of 0.8896. Furthermore, the model improved the accuracy of OCR to 99.9% using Google Cloud Vision OCR, underscoring its effectiveness in restoring license plate readability under glare conditions. Computational efficiency was a key focus, with a compact model size of 298 kB and a runtime of 0.7263 s, making it scalable for real-world deployment. Despite encountering limitations such as dataset bias and computational constraints, this research provides valuable insights and lays the groundwork for future advances in glare mitigation, image processing, and machine learning-based LPR enhancements. The findings have broad implications for transportation management, public safety, and automated enforcement, offering a robust solution to improve the performance and reliability of LPR systems in diverse real-world applications.

    (Makerere University, 2025) Yahaya, Saidi
    Financial inclusion is a key driver of economic growth, particularly in developing countries where large portions of the population, especially women, remain unbanked and underserved by formal financial institutions. In Uganda, over 54% of financially excluded adults are women, who face significant barriers to accessing digital financial services, including affordability, lack of digital literacy, and socio-cultural restrictions. These challenges limit their ability to save, access credit, and participate fully in the digital economy. Despite various initiatives, a significant gap remains in addressing the specific challenges women face in accessing and utilizing digital financial services. The purpose of this study was to develop a digital finance model aimed at enhancing the financial inclusion of women in Makindye Division, Uganda. The study sought to identify requirements for the digital finance model for financial inclusion of women, design a digital finance model for financial inclusion of women in Makindye division and test the effectiveness of the designed digital finance model. A mixed-method approach was employed, combining both quantitative and qualitative data collection. Survey questionnaires were administered to 362 women while in-depth interviews were conducted with 10 mobile money/banking agents within Makindye Division. The quantitative data was analyzed using IBM-SPSS for descriptive and inferential statistics, including correlation and regression analysis, to test the relationships between digital finance and financial inclusion. The results revealed significant positive correlations between digital finance and financial inclusion, with digital infrastructure access, digital literacy, affordability of digital financial services, perceived risk and privacy concerns being critical factors. The study found that women face several barriers, including limited access to digital devices, poor network quality, high costs of internet services, and lack of formal training. The developed digital finance model was tested as an effective tool for enhancing financial inclusion among women in Makindye division.

    (Makerere University, 2025) Ajuna, Newton Brian
    Uganda’s public sector continues to face significant challenges in information sharing and reuse among Ministries, Departments, and Agencies (MDAs), despite notable investments in ICT infrastructure and e-government systems. Fragmented data ecosystems, limited interoperability, and redundant data management processes hinder effective service delivery. This study addresses these challenges by proposing a context-specific framework for supporting secure and scalable information sharing and reuse across MDAs. Grounded in a thorough literature review and a comprehensive analysis of Uganda’s institutional context, the study adopts the Design Science Research (DSR) methodology. Through iterative design, evaluation, and refinement cycles, the study integrates findings from document reviews and empirical data collected via a national survey targeting ICT professionals and data managers. Key challenges and requirements were categorized using the PESTEL (Political, Economic, Social, Technological, Environmental, and Legal) framework. The resulting framework SIRAM (Supporting Information Reuse Among MDAs) is an adapted version of Estonia’s X-Road framework, extended to suit Uganda’s unique governance and operational environment. SIRAM incorporates components such as policy harmonization, metadata standards, legal alignment, stakeholder trust-building, and capacity development. Visual modeling was conducted using Visual Paradigm. To evaluate the framework, structured walkthroughs were conducted with 15 experts from URA and peer MDAs. Evaluation results confirmed the framework’s conceptual relevance, usability, and institutional applicability. The study concludes by emphasizing the need for coordinated legal reform, investment in capacity-building, and centralized governance structures to unlock the full benefits of e-government interoperability in Uganda. Future studies may extend the framework by testing its scalability across MDAs, integrating with UGHUB, and examining policy adoption challenges. Future work will pilot SIRAM across additional MDAs and refine governance, legal, and technical guidelines by sector. It will also evaluate capacity needs and the costs and benefits of nationwide adoption.

    A knowledge management portal to support the sharing of best practices in community-based obesity prevention and advocacy in Uganda
    (Makerere University, 2025) Kamukama, Diana
    Obesity has gradually become a silent epidemic in Uganda, contributing to rising rates of diet-related non-communicable diseases (NCDs) such as hypertension, type 2 diabetes, cardiovascular disease, and certain cancers leading to increased mortality. This alarming trend has placed considerable strain on Uganda’s health system and highlights critical gaps in community-level knowledge about effective practices for preventing and managing obesity. With limited focus by the government on actions that specifically target the prevention and management of obesity, there is a growing need for increased advocacy, particularly through knowledge sharing to engage communities in physical activity and promote diet modifications for healthier lifestyles. Knowledge Management (KM) has been proven to be a valuable approach to addressing health knowledge gaps by enabling access to, sharing of, and application of evidence-based practices within communities. However, the effective implementation of KM in the obesity care continuum remains largely untapped in Uganda. This study addresses that gap by developing a Knowledge management portal for Obesity Prevention and Advocacy (KOPA), a digital platform intended to serve as a single point of access to evidence-based best practices for obesity prevention and advocacy, targeting both healthcare professionals and community members. Using an Action Research approach, this study identified key challenges and user requirements that informed the portal’s design and implementation. KOPA combines a searchable library of best practices on healthy eating and physical activity, collaboration tools, content for different user groups, simple obesity-tracking, and clear Uganda-specific guidance on healthy lifestyle change. Evaluation with healthcare professionals and community members found it relevant, easy to use, and helpful for finding, organising, and sharing practical information that supports behaviour change. KOPA shows how a centralized, knowledge-driven platform can strengthen obesity prevention and advocacy in resource-constrained settings. Future work includes expanding multilingual content, introducing lightweight mobile access, connecting with Ministry of Health resources, and running a multi-site evaluation to confirm gains in knowledge, activity, and diet quality.

    A model driven serious game generator : a case of Android quiz game
    (Makerere University, 2025) Afema, Deogracious
    Computer games are used in several areas encompassing fun and serious contexts. Game development however is a complex technical undertaking with resulting financial costs exploding into millions of dollars for the most complex games. As a result , Model Driven Development (MDD) has been used in several studies to simplify software development and develop domain specific artefacts. This study explored the use of Model Driven Development (MDD) in serious game development with a focus on quiz games. Quiz games are a simple game domain that can easily be modelled. Corresponding graphical and other tooling can also be developed to ease game development. With existing evidence of the effectiveness of games in effecting positive learning outcomes and policy shifts allowing learners to have digital devices in schools, serious games hold great potential to shape positive learning outcomes. This study identified serious game features, identified the features missing from the existing quiz game modelling languages, modelled select features missing from the existing languages and developed a model editor to facilitate a no code approach. The study found out that while there were existing modelling languages for quiz games, they did not incorporate several serious games features despite the applicability of the said features to the quiz game domain. With the new features added to the existing modelling language AskMe, five games were prototyped to reflect the applicability of the features to quiz games. A formal verification tool (Microsoft z3) was also used to check the generated models for correctness covering both positive and negative outcomes. Finally this study developed a model editor for the extended language. Through analysis of quiz game requirements specified in existing serious quiz games, this study found out that the extended language covered the specified requirements in a more robust manner. The major contributions of this study include the extension of the quiz game modelling language AskMe to make it more suitable for serious game applications. This study introduced progress tracking, level based game challenges among others that were missing from AskMe. This study also introduced a graphical model editor as an additional tool to enable creation of quiz game models with little to no programming skills.

    A model for enhancing career selection systems: a case of Ugandan secondary school students
    (Makerere University, 2025) Tuhame, Moses Kamondo
    Career selection in developing countries is often guided by traditional methods such as teacher- led sessions and examination results yet these approaches fail to account for the complex and multi-dimensional factors influencing career choices. As a result, many students make decisions based on guesswork, peer pressure or parental influence, leading to career mismatches and wasted potential. Although ICT-based career selection tools have been of help, they remain generic and overlook Uganda’s socio-economic and cultural realities. Recent advancements in Artificial Intelligence (AI) and Machine Learning (ML) have strengthened predictive capabilities in career selection systems; however, these technologies rely on limited variables and are largely designed for developed contexts. This study therefore aimed to develop a model that enhances the performance of the existing Career Selection Systems for secondary school students in Uganda. Guided by Social Cognitive Career Theory (SCCT) and Holland’s Vocational theory, the model integrates socio-behavioural and contextual variables to enhance the variables of the existing career selection systems to reflect the realities of Uganda. The study adopted pragmatism research paradigm and employed Design Science Research strategy with both quantitative and qualitative data collected from secondary school and university students and career guidance stakeholders. Data were analysed using SPSS, NVivo, and PLS- SEM. Eight key SCCT variables were identified for the model: Contextual Influences, Contextual Affordances, Learning Experiences, Career Goals, Outcome Expectations, Self- Efficacy Expectations, Personality, and Career Decision-Making. The model demonstrated good statistical fit, with 3.2% of variance in enhancing career selection. Additional qualitative insights highlighted five additional factors for model improvement. Model evaluation showed strong support, with expert walkthroughs yielding a 79.3% satisfaction rate and prototype testing with 51 users recording an 80% satisfaction rate. These results demonstrate that the model is both robust and adaptable, making it suitable for integration into technology-supported career selection systems, including AI- and ML-based platforms in Uganda and similar contexts. Future work should include a longitudinal study to assess the long-term impact of the model on students’ career trajectories from school to employment, alongside the development of a mobile version of the prototype to enhance accessibility and usability. Additionally, integrating the model into existing career selection systems, particularly AI- and ML-based platforms, is recommended to improve system performance and support wider adoption.

    A model for user acceptance of digital banking services by the informal sector in Uganda: a case of Kampala Owino market traders
    (Makerere University, 2025) Ashaba, Jacenta
    Despite the high penetration rates of digital banking services in developed countries such as UK with 71% and Finland with 74%, the user acceptance of digital banking services is still low in Uganda. For example, ATM is 1%, debit card usage is 28%, credit card is 14% while POS is 20%. This study aimed at developing a user acceptance model for digital banking services by the informal sector in Uganda, a case of Kampala Owino Market traders. In this study, Design Science was adopted to achieve the goals of the study. Primary data was obtained from 200 Owino market traders in Kampala city using a questionnaire tool. Data analysis involved computation of descriptive statistics, Pearson Correlations and multiple linear regression on user behaviour of digital banking services. Hypotheses testing was conducted on Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), Facilitating conditions (FC), Hedonistic motivation (HM), Price Value (PV) and Behavioural Intention (BI) of Owino market traders who had bank accounts. The model testing and validation was done using a validation questionnaire. The questionnaire was presented to 150 Owino market traders and 14 information system practioners/analysts to capture responses on acceptance levels of digital banking services. Descriptive statistics of the respondents was achieved using SPSS software while model validation was done using Pearson correlation coefficient and multiple linear regressions to test the study hypothesis. The results showed that Performance Expectancy, Effort Expectancy, Hedonistic motivation and Habit had moderate positive significant effect on User acceptance of digital banking services while social influence, facilitating conditions and Behavioural intentions had weak negative insignificant effect on user acceptance of digital banking services. The study recommends that Banks should ensure full time availability of the network for all digital banking services, stakeholders in the banking sector should work hand in hand with system vendors to develop application designs that are user friendly for most customers in the informal sector given their little knowledge on the usage of these applications. In conclusion, the study notes that user acceptance of digital banking services in the informal sector is largely influenced by Performance Expectancy, Effort Expectancy, Social Influence, Facilitating conditions, Hedonistic motivation, and Behavioural Intention.

    Addressing the challenges of the information and knowledge societies : the case for optimum curriculum in the SCECSAL Region
    (SCECSAL, 2004) Kigongo-Bukenya, I. M. N.
    The paper rotates on the question whether Information Management (IM) curriculum is equally appropriate for Knowledge Management (KM). Using the Conceptual Framework of Knowledge Management Processes (CFKMP), the concepts "Information Management" and "Knowledge Management" are explained and related in the context of optimum curriculum. The processes/activities of information management and knowledge management are examined to identify similarities or differences and to establish the base of knowledge and competencies/skills required. Based on Coral (2005) and comparative analysis of other literature, it is estimated that both IM and KM professionals require similar knowledge and skills competencies. It is deduced therefore that the same curricula would be appropriate for both. The paper further suggests that two strategies could be adapted in teaching of such curricula. The first would be the core-elective approach, whereby IM and KM are taught as electives along the core required by the information profession. The second would be the specialization strategy approach by which IM and KM are taught as different programmes.

    An adherence monitoring system in antiretroviral therapy
    ( 2007-05) Otine, Charles Daniel
    This study investigated the use of a Multi-dimensional system to improve adherence monitoring in antiretroviral therapy (ART). The high adherence levels required during patient therapy and the consequences of adherence failures (virus mutation to drug resistant strains, treatment failure, fatality) necessitated this study, with the hope that the development of a system would provide a basis for deployment of similar systems in other ART providing centers. An ART providing health centre (Mbuya reach out) was selected as a case study, with data collected from the centre used as a basis for the system design, development, testing and validation. Data was gathered through interviews, content analysis and direct observation; the rational unified process (RUP) of system development was then used to develop the system. Unified modeling Language (UML) was used to document the system development process, producing artifacts such as use case models, domain models, collaboration diagrams and System sequence diagrams. The final system was entirely implemented in open source (MySQL and PHP) and hosted to an online web server with the findings revealing that adherence monitoring can indeed be improved by using the system, but there is still need for further research in protecting the data and the tweaking of the system to enable monitoring not only for adults but for children as well. It is recommended that leading ART providing centers in conjunction with Ministry of health champion the use of the system by training users to exploit the functionality of the system, and encourage use of the system with a goal of developing a comprehensive information base for future studies on adherence.

    An adjustable usable security approach for a continuous user authentication scheme
    (Makerere University, 2019-11) Kaburu, Dennis
    The advent of the internet and associated technologies have revolutionized the way we live and work. Today, organizations both public and private rely heavily on computer-human interaction systems to deliver services. The quality and reliability of services delivered by these systems depends on controlled access to these systems. Within this realm, security issues of interactive systems are gaining more than ever the attention not only from a technical and security perspective but also from the user's point of view. The security community has come to understand the critical importance of usable security, which is primarily focused on designing secure systems that people can use. In mission, critical systems like online examination and military intelligence, there is need to verify constantly the identity of the user throughout the session of interaction (referred to as “continuous user authentication”). Design and development of continuous user authentication schemes represents a cross-roads priority problem, between security and usability, which emerge from contradictory requirements posed by different stakeholders, inherent to the function and purpose of each security mechanism. Information security experts and information security researchers’ goal is to ensure a high security continuous user authentication scheme while at the same time user experience design experts and researchers (UX) envisage an adaptable, user-friendly solution. This makes the service providers of continuous authentication schemes find a viable balance among security and usability attributes. Accordingly, researchers have proposed a number of approaches to address the issues of continuous user authentication. However, these approaches require user collaboration, which affects user performance on the core tasks in the business processes because of user task interruptions. Thus, the approaches have usability challenges. Henceforth, this work attempts to revisit the definition of usable security by advocating for an alternative approach that enhances the alignment of security and usability attributes to achieve a better synergetic relationship in continuous user authentication schemes. The main focus is to improve usability of user interactions in continuous user authentication schemes according to a user perceived trust obtained from a user dynamic behavior and cognitive-centered technique that reduces disruption of a user during re-authentication. The high level objectives of this thesis are (i) to develop an adjustable threshold approach for a continuous user authentication scheme that enhances synergetic relationship between usability and security attributes; (ii) to develop a low disruptive re-authentication technique that applies when the trustworthiness of a user is below the adjustable threshold; (iii) to validate the re-authentication technique.

    (Makerere University, 2020-12) Nakawuka, Josephine
    As a solution to the low citizen engagement, it is important to increase the number of citizens who participate in policy-making and governance. To fully enjoy the benefits of eGovernance, the citizens should be able to participate in it fully through offering their views, contributions, and ideas in order to build general development of their societies and country at large. Despite the countless benefits of citizen participation in eGovernance, it is still low in the governance space. The aim of this study was to identify the factors affecting citizen participation, design a model to support citizen participation in eGovernance, and also evaluate this model to understand its contribution to eGovernance. The study employed the Participatory Action Research methodology because it clearly mapped out our objectives and its cycle was the most relevant for our results achievement. With the use of purposive sampling, convenience sampling, snowball sampling, and data analysis software, relevant data for the research was collected, analyzed, and used to fulfill the objectives of this study. This research provided a solution to the ailing number of citizens participating in eGovernance in the country through the development of an eGovernance adoption model for citizens to support their participation in eGovernance. The study entailed the detailed description of eGovernance in society, citizen participation in eGovernance, the role of Web 2.0 technologies in eGovernance citizen participation, and their contribution to the fulfillment of the study objectives. This study also suggested areas of future research to strengthen eGovernance as a whole and also the overall participation of citizens in eGovernance.

    Adoption of e-tax services in Uganda : the perspective of the technology acceptance model
    ( 2012) Maiga, Gilbert ; Asianzu, Elizabeth
    The diverse benefits of e-government services are linked to its adoption and usage. E-government adoption rates in economically transiting countries remain low and so its benefits are not fully realized. This is partly because-governments have focused largely on the technical supply-side factors with little emphasis on the demand or consumers’ perspective of e-government adoption. The result has been a gap between what is offered and what is consumed. This paper presents the results of a study that develops a model for e-tax service adoption as an attempt to bridge the gap for this segment of e-government. Requirements for the model elicited in a field study are used to extend the Technology Acceptance Model which emphasizes consumer-based factors for e-tax adoption. The extended model has dimensions of adoption benefits, trust, attitudes, education, compatibility, awareness, accessibility, training, user support and local language use. It is generic and reusable for other countries in similar context.

    Agriculture and land use planning problems are multifaceted in nature and require information and data incorporation from different sources and disciplines. This dissertation gives an account for the development and implementation of an Agricultural Information System for Land use Planning in Kumi district of eastern Uganda. Stakeholder Analysis (SA) as an approach to gaining understanding of a system by means of identifying key stakeholders and assessing their respective interests has been explored. Structured System Development Methodology (SSDM) was used to elicit the data requirements, data availability, integration and model information processes and data for land use and resource planning. A prototype information system for land use planning and a relational database were designed towards the provision of land use and resource data required for land use and resource planning in Kumi. A user interface was designed for stakeholders to access and update the database. Hyper text Preprocessor (PHP) was used to design the front end of the system with MySQL at the back end. Three perception based variables (perceived ease of use, perceived usefulness and intension to use) were subjected for measurement and the experimental results of one t-test on the value of each construct found the values of all dependent variables significantly positive. This suggested that the system has a high likelihood of adoption in practice. Internet Explorer 4/7 can be used to browse the information. Users have rights to update the database information but the Database Administrator has rights to modify the database by adding or removing users.
