Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

Designing A Compact RGB 14-Segment Display

Sometimes you’re looking for a component for a project that you know should exist, but you just cannot find it. Something like a 14-segment LED display, but not just one with a fixed color, ...

SICNav: Safe and Interactive Crowd Navigation Using Model Predictive Control and Bilevel Optimization

Abstract: Robots need to predict and react to human motions to navigate through a crowd without collisions. Many existing methods decouple prediction from planning, which does not account for the ...

Engineers builds Arduino-led game console from a fidget clicker and I want to fidget with it so badly

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

Nonlinear Optimal Midcourse Guidance Using Sequential Pseudospectral Model Predictive Control

Abstract: A sequential pseudospectral model predictive control (SPMPC) method is proposed for nonlinear optimal midcourse guidance with a general performance index. First, the optimal midcourse ...
