Portable ultrasound device from MIT could enable at-home breast monitoring. Weighs just over 1 pound, matches hospital imaging performance.

Abstract: Large-scanned antenna arrays need to be periodically calibrated to correct for errors in excitation amplitude and phase, which degrade performance. The ability to adjust complex excitations ...

US industry experts trace the evolution of PV rapid shutdown rules and outline how recent updates to UL 3741 are reshaping compliance pathways for rooftop and commercial solar in the United States.

Ryan Mayfield led an informative discussion on the history of the NEC PV Hazard Control System rules and the latest changes to the UL 3741 standard.

With the increasing penetration of photovoltaic (PV) systems into power grids, the accurate diagnosis of PV array health has become critical for ensuring the stable operation of power systems. To ...

ABSTRACT: The adoption of photovoltaic (PV) systems in modern electrical grids has expanded rapidly due to their economic and environmental benefits. However, these systems are prone to faults—such as ...

I am not sure whether this is a bug in the code, rather than an error in the documentation, so I will start to describe it here, and if it turns out to be something ...
