Comb-based optical frequency metrology and atom clocks have pushed the measurement of time and frequency to unprecedented precision in recent decades 1. The recently ...

Most modern industrial facilities have widespread applications of nonlinear loads, many of which represent a significant portion of the total facility load. As a result, they can inject harmonic ...

AnalogDevices (ADI) is shipping samples of its ADE7880 3-phase energy metering IC forpolyphase meters, which employs its latest harmonic analysis technology foradvanced power quality monitoring.

Industrial and commercial customers constantly scrutinize their monthly electrical usage, looking for ways to save money. Installing power factor correction capacitors can reduce costly penalties ...

Harmonic comb generators have been available for a long time and are useful for many purposes. They produce a fixed series of harmonic signals with stable frequency and amplitude over a range of ...

This paper rigorously analyses preconditioners for the time-harmonic Maxwell equations with absorption, where the PDE is discretised using curl-conforming finite-element methods of fixed, arbitrary ...

Musical instruments and throats create different notes by making the air around them vibrate at particular frequencies (check out part one to find out how they do it). When you pluck the A string on a ...
