Abstract: In this paper, equivalent electric circuit models of a commercial 1.2-kW proton exchange membrane (PEM) fuel cell stack are proposed based on AC impedance studies. The PEM fuel cell stack ...

The subthalamic nucleus contains subpopulations with different contributions to deliberative decision-making based on noisy evidence and reward-driven preferences.

EMS workouts are on the rise on social media, with users reporting increased muscle, but experts say they should stick to conventional weightlifting instead.

A recent BVLOS lidar operation for a regional electric utility showcases how long-range corridor inspections can be highly cost-effective.

Abstract: This article presents two equivalent electrical models of electrospray thrusters verified with experimental data. The first model presented in this article aims to improve the electrospray ...

Finding places to deploy new solar panels is often just as challenging as the construction project itself – with productive farmland, open parking lots, and rooftops all offering their own sets of ...

Tesla says engineering tests of its first production Cybercab have begun in Austin — but the robotaxi still has a human ...
