    The challenges of running federated learning (FL) in resource-constrained browser environments, such as limited GPU access and interruptions, are caused by tab closures or page refreshes. To address this, the FLEXIBLE learning ecosystem introduces a browser-based federated learning system that enables decentralized model training without sharing raw data, preserving user privacy and enhancing accessibility. Built on a microservices architecture with Kafka for asynchronous, fault-tolerant communication, the system allows users to participate without software installation. Experiments on a super-resolution task reveal performance disparities across devices - mid-range performance mobile laptops achieved complete zero-shot super-resolution (ZSSR) training-inference cycles under 3 seconds, while mobile devices took up to 13.78 seconds. Notably, image patching proved essential for enabling large-image processing in browsers, offering a key insight into optimizing FL in low-resource environments.

    The main processes of outcome-based education management are setting learning outcomes, measuring, evaluating learning results, and improving. Teachers must plan exercises, homework, classroom activities, midterm exams, and final exams that are consistent and align with program outcomes and educational standards. The proposed Outcome-Based Education (OBED) Web Application supports administrators and faculty staff for program and course management. After administrators or course committees designed the program learning outcomes to meet the referred educational standards (ex. TQF and TABEE), this web app supports their alignment PLOs to courses. Then, faculty staff can create expected course learning outcomes connected to the assigned PLOs. In addition, the system supports data transfer from the learning management system. With this web app, administrators and teachers can observe student outcomes from student activity results compared with the expected program learning outcome reported by course, cohort, or individual student. Therefore, teachers can adjust activities during the semester to get much closer to the target expected PLOs. Moreover, by OBED app support, semester assessment reports are ready to use according to the form prescribed by departments and educational standards.
