A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

Abstract: Light emitting diodes (LEDs), with their ability to produce tunable light spectrums, present a significant opportunity to improve on existing lighting systems. They can be applied to smart ...

Abstract: This paper describes the design and implementation of an autonomous traffic light system, with traffic-based timing for improving traffic flow efficiency in urban roads. The importance of ...
