Real‐Time Data‐Driven Fault Diagnosis of Photovoltaic Arrays Using an Edge‐Server Machine‐Learning Framework

Energy Science &Engineering, Volume 14, Issue 6, Page 2961-2982, June 2026.
A real‐time, data‐driven framework detects and classifies photovoltaic array faults using edge sensing and server‐side machine learning. Ensemble tree models achieve near‐perfect accuracy with low latency, enabling practical, low‐cost deployment for reliable PV monitoring and intelligent maintenance.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Decline of Visual Function and Risk of Legal Blindness With Age in RPGR ‐Associated Retinal Degeneration: A Multicenter Study

Clinical &Experimental Ophthalmology, Volume 54, Issue 4, Page 482-491, May/June 2026.
ABSTRACT Background This retrospective multicenter longitudinal analysis analysed the loss trajectory of best recorded visual acuity (BRVA) and Goldmann visual field (GVF) in RPGR‐associated retinal degeneration (RPGR‐RD). Methods Patients with genetically confirmed RPGR‐RD were classified into rod‐cone (RC), cone/cone‐rod (CR) and female‐carrier ...
