Item Open Access Enhancing Cognitive and Metacognitive Domains of Autistic Children Using Machine Learning(Multidisciplinary Digital Publishing Institute (MDPI), 2025-08-21) Tharaki, D; Rupasinghe, Y; Ruhunage, P; Pehesarani, A; Rathnayake, S.CASD poses special difficulty in both cognitive and metacognitive development, necessitating specialized educational strategies. This research proposes LearnMate, a web-based application powered by machine learning techniques that aims to improve the abilities of children with autism. Utilizing classification models learned from medical data, LearnMate forecasts skill acquisition and suggests personalized learning activities according to the strengths and developmental requirements of the child. The system permits instructors to monitor progress through real-time feedback, enabling adaptive learning approaches. Pilot application to more than 100 children showed significant gains in their skills. The results demonstrate the immense potential for change through machine learning in special education to facilitate data-driven, personalized learning opportunities that enhance the capabilities of both autistic students and teachers.Publication Embargo Probing the Effect of Salicylic Acid on the Post-harvest Changes in Cordyline fruticosa Using OJIP Chlorophyll Fluorescence Transient Analysis(Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Wijethunga, W. M. U. D; Jayasooriya, L. S. H; Kumarihami, H. M. P. C; Dissanayake, U; Beneragama, C. KUse of proper postharvest treatment is vital to ensure a longer postharvest life in ornamental plant production including cut-foliage. Although Salicylic Acid (SA) is a promising postharvest treatment, to maintain postharvest quality of many cut foliage species, its direct impact on the photosynthetic process has debatable outcomes as reported by various researchers. In this study, we attempted to investigate the effect of SA on the postharvest performance in cut foliage using OJIP analysis. Two concentrations of SA (100 and 300 mg/L) with a watercontrol were tested with cut-leaves of Cordyline fruticosa var Willy’s gold at room temperature (25±2°C). OJIP parameters, i.e., specific energy fluxes (ABS/RC, TR/RC, ET/RC, and DI/RC), flux ratios (maximum quantum yield of primary photochemistry-φPo), electron transport efficiency (ψo), quantum yield of electron transport (φEo), and performance index (PI) were recorded every other day using a fluorometer (FluorPen FP). Leaf chlorophyll, anthocyanin contents were also determined using spectrophotometry. Data were analysed according to completely randomized design (CRD). The PI increased in both SA treatments up to the 7th day of treatment. SA at 300 mg/L had a significant effect on most of the OJIP parameters, specific fluxes in particular. SA treated leaves exhibited higher on the retention of chlorophyll. Except φPo all other flux ratios were significantly affected by the SA treatment indicating its impact on the photosynthetic apparatus but most probably in retarding the ethylene biosynthesis as reported elsewhere. SA extends the vase life of Cordyline fruticosa cut leaves. Moreover, there is an effect of SA on the photosynthetic machinery; net photosynthesis proved the OJIP results. The underlying mechanism warrants further studies.
