Modeling, Simulation and Optimization of Solar Power Generation and Transmission in Uganda
(2024) Ounyesiga Living
This study addresses key challenges in the optimization and modeling of power systems, encompassing three main areas. Firstly, it analyses the traditional minimization of power losses in transmission lines, dominated by artificial intelligence techniques that lack a guarantee of global optimum. The gradient technique was introduced to efficiently minimize power losses by modifying the traditional power loss model. Empirical validation on specific transmission lines in Uganda demonstrates the superiority of the modified model in minimizing power losses. Secondly, this study highlights the dominance of lumped models in transmission systems, lacking space considerations and hindering the simulation of transmission losses. To address this, a proposed distributed or coupled system of thermal and power equations, accounting for both space and time was validated through simulations and empirical data from the Bujjagali - Kawanda transmission line. Lastly, the research focuses on the alarming underperformance (about 35%) in solar power generation in eastern Uganda, attributing it to the absence of extrinsic factors in the nominal cell operating temperature (NOCT) model. The study empirically introduced the missing factors and develops a mathematical model of second-order differential with empirical solar power generated in Busitema, Mayuge, Soroti, and Tororo study areas. The unmodified (modified) models for Bujagali – Kawanda 220 kV and Masaka West – Mbarara North 132 kV transmission lines in Uganda showed maximum power losses of 0.406023685 (0.39112869) and 0.451933075 (0.445513943) kW/km/phase respectively. Secondly, the transmission percentage losses ranged from 0.03 to 0.06%, which is consistent with the 3.6% recommended by the Electricity Regulatory Authority, Uganda. Thirdly, based on the RMSEs (0.6437, 0.6692, 0.2008, 0.1804, respectively), the gaps between designed and operational solar power generation were minimized. Furthermore, Mayuge recorded the highest solar power generation of 9.028 MW compared to Busitema (8.622 MW), Soroti (8.901 MW), and Tororo (8.345 MW), suggesting that it has a conducive site for installing future solar plants. The above results are useful for operation, design and management of solar power generation and transmission in Uganda and elsewhere.

Mapping a Decade of Avian Influenza Research (2014-2023): A Scientometric Analysis from Web of Science
(Journal of Health Information Research, 2026) Muneer Ahmad; Undie Felicia Nkatv; Amrita Sharma; Gorrety Maria Juma; Nicholas Kamoga; Julirine Nakanwagi
This scientometric study analyzes Avian Influenza research from 2014 to 2023 using bibliographic data from the Web of Science database. We examined publication trends, sources, authorship, collaborative networks, document types, and geographical distribution to gain insights into the global research landscape. Results reveal a steady increase in publications, with high contributions from Chinese and American institutions. Journals such as PLoS One and the Journal of Virology published the highest number of studies, indicating their influence in this field. The most prolific institutions include the Chinese Academy of Sciences and the University of Hong Kong, while the College of Veterinary Medicine at South China Agricultural University emerged as the most productive department. China and the USA lead in publication volume, though developed nations like the United Kingdom and Germany exhibit a higher rate of international collaboration. "Articles" are the most common document type, constituting 84.6% of the total, while "Reviews" account for 7.6%. This study provides a comprehensive view of global trends in Avian Influenza research, emphasizing the need for collaborative efforts across borders.
