Item Steganalysis model for detecting and recovering stego images(2026) Nabirye, BarbraThe National Information Technology Authority of Uganda (NITA-U) lacks effective steganalysis capabilities, leaving government systems vulnerable to covert data exfiltration and hidden communication channels exploited by malicious actors. While encryption secures message content, it does not conceal the existence of communication—a limitation that steganography overcomes by hiding information within innocuous digital media. This study designed, implemented, and experimentally evaluated a steganalysis model to detect, decipher, and recover hidden information from digital image files within the NITA-U context. Using an experimental design, the Least Significant Bit (LSB) technique was implemented in Python with OpenCV and Pillow. A dataset of 45 images was assembled from USC-SIPI, BOSSBase v1.01, and NITA-U operations. Evaluation metrics included PSNR, SSIM, MSE, chi-square analysis, classification metrics, and three feature detection methods (Shi-Tomasi, ORB, Harris). Results showed successful hiding and retrieval of text and image payloads without quality loss. The tool achieved PSNR values of 52.34–54.18 dB (exceeding the 40 dB threshold) and SSIM values of 0.9978–0.9984, confirming imperceptibility. Chi-square statistics (2.14, 1.87) fell below the critical threshold of 3.84, confirming statistical undetectability. No feature detection method distinguished stego images from cover images at significant levels (p = 0.68, 0.72; 94.7% match rate). The proposed model achieved 93.3% detection accuracy (F1 = 0.903) and significantly outperformed Steghide, OpenPuff, and F5 (ANOVA: F = 16.98, p < 0.001).Item 48 irrigation schemes constructed, 30 in pipeline(New Vision, 2018-05-18) Tenywa, Gerald; Amamukirori, BettyThe Ministry of Water and Environment is constructing 48 new small and big irrigation schemes in order to increase food security and resilience against climate change impacts.Item President Museveni's simplicity: Why all water is not safe for irrigation(New Vision, 2017-01-06) Kanyarusoke, Kant AteenyiAre you inventing a rain-making machine? A close relative and childhood playmate, now in Kampala- Grace Kiiza- teased me during my protracted doctor of engineering research in solar energy. She had learnt I was working on some solar-related invention and both of us were concerned about the changing climate of the country leading to droughts even in regions that had been wet during our youth.Item Technology to facilitate agricultural financing.(Daily Monitor, 2017-10-05) Ladu, Ismail MusaSmall holder farmers have for years been unable to access credit, hindering their transformation from subsistence farming to commercial agriculture, sector experts have said. According to the chief operations officer of aBiTrust, Ms. Josephine Mukumbya, whose organisation guarantees credit extended to farmers, small holders farmer financing comes with huge risks,Item Makerere builds solar power irrigation pump(New Vision, 2017-01-06) Nantambi, AgnesMakerere University's college of Agricultural and Environmental Sciences has fabricated a solar-powered pump with capacity to irrigate up to 10 acres.Item Guidelines for agriculture mechanisation in the offing(New Vision, 2018-04-03) Nandudu, ProssyThe Agriculture ministry is drafting a policy that will guide the country on how to design appropriate interventions in agriculture mechanisations.Item Did you know?
