When a baby smiles at you, it’s almost impossible not to smile back. This spontaneous reaction to a facial expression is part of the back-and-forth that allows us to understand each other’s emotions ...

Welcome to the Department of Physics and Astronomy at the University of Delaware, where the pursuit of scientific discovery and innovation meets cutting-edge research and academic excellence. Our ...

Scientists have spent decades trying to pin down what fatigue really looks like inside the brain, but until now they have mostly been stuck with snapshots instead of a full day’s story. New work using ...

Abstract: Thin-film Transistors (TFTs) have garnered recent research interest in the development of flexible displays, due to their low fabrication costs and high-volume production. In displays, ...

This project demonstrates Li-Fi (Light Fidelity) communication between two Arduino boards using visible light for data transmission. Text data is transmitted using an LED and a 4x4 keypad on the ...

Abstract: Traditionally, a continuous-wave (CW) signal is used to simulate RF circuits during the design procedure, while the fabricated circuits are measured by modulated signals in the test phase, ...
