These papers are from undergraduate research in Production and Industrial Engineering at Delhi Technological University, around 2014. They are earlier work, distinct from current work in security compliance, private cloud, and applied AI.
Condition monitoring of roller bearings under dynamic loading using contactless infrared thermography. Temperature characteristics of normal and defective rotating ball bearings were compared to evaluate whether thermography can diagnose faults qualitatively and quantitatively.
Vibration analysis of rolling-element bearings under a dynamic loading model, using time- and frequency-domain measurements from a vibration analyzer. Non-defective bearings showed a smooth, decreasing velocity trend; defective bearings showed an interruptive upward trend useful for defect detection.
A survey of energy harvesting from human activity and ambient sources, including walking, breathing, and gym equipment such as treadmills and bicycles, and how conversion technologies can power low-power electronics or contribute renewable energy.
