Lean Learning Through VSM
Abstract: Prof P Tthareja 12.00 The word “Lean” encompasses more scope than what has been perceived in Industrial Sector. The current paper explores its benefits in the sectors with more complex supply chain than industrial sectors, namely education. Lean thinking allows a simple route for improving efficiencies by, identifying margin of errors, and further by improving teaching effectiveness. In the current paper use of value stream mapping in educational institute is …

Automatic Classroom Lighting Controller and Energy Saving Based on Microcontroller Unit
Abstract: The rise in energy costs urged the need in minimizing the energy consumption. As significant amount of energy is used for illuminating in educational buildings such as lecture halls and lecture rooms, improvement is needed to avoid energy wastage for unoccupied and during daylight hours. The lighting will be controlled based on demand to save the energy costs. This paper introduces the common existing problem that lights work in classrooms …

SmartTrack : Advanced Attendence System using LR RFID
Abstract: This project presents the design and implementation of a long-range RFID attendance system aimed at transforming how educational institutions track attendance by making the process faster, more accurate, and completely contactless. Tradi- tional methods, whether manual roll calls or short-range RFID scanners, often interrupt class routines and leave room for errors or proxy attendance. To address these issues, the proposed system integrates long-range RFID readers, beam sensors, and ESP32 microcontrollers …
