Harmonics of the 60 Hz power frequency has been around for a long time. It was observed on transmission systems in the early 1890s and was associated with voltage and current waveforms. As equipment ...

In the event of a breakdown, any number of issues may be the culprit, but there’s one in particular that’s particularly challenging to diagnose: resonance. Resonance can be a problem in any machine, ...

Inverse problems involve deducing the underlying characteristics of a system from observational data, rather than from direct measurement. In the realm of differential operators, this approach focuses ...
