Generation of Electricity with the Help of Speed Brakes
Abstract: Electricity is produced by replacing the conventional speed breakers with some simple mechanism. As vehicles pass over the speed breakers, they spin the rollers which are connected to a generator which in turn generate electricity. This method is an effectual way to produce electricity as the numbers of vehicles on the road are ever increasing. Also, the price of fabrication of the model is less. It can be effectively placed …

The Biomechanical Impact of Slipper Sole Compliance on Lumbar Spine Load: A Quantitative Analysis of Indoor Footwear Ergonomics
Abstract: Abstract The global shift toward remote work has significantly increased the duration of indoor footwear usage, yet the ergonomic standards for slippers remain critically under-researched compared to athletic or industrial footwear. While "high-compliance" or soft slippers are traditionally marketed for immediate comfort, excessive mechanical softness may lead to foot instability, altered gait kinetics, and subsequent compensatory stress on the lumbar spine. This study aims to quantify the correlation between varying …
