CURRENTS OF SINGLE-PHASE INDUCTION MOTORS SUPPLIED WITH VOLTAGE CONTAINING INTERHARMONICS
Scientific Journal of Gdynia Maritime UniversityIn real power systems the voltage waveform is not a perfect sine, but contains various additional frequency components, like harmonics, and in some power systems also subharmonics and interharmonics, that are components of frequency less than the ...

On delta $m$-subharmonic functions
Annales Polonici Mathematici, 2016 Let \(\Omega\subset \mathbb C^n\) be a bounded \(m\)-hyperconvex domain, i.e, a domain for which there exists a bounded \(m\)-subharmonic exhaustion function, and assume \(1\leq m\leq n\). Let \(\mathcal E_{0,m}\) be the class of bounded \(m\)-subharmonic functions \(u\) in \(\Omega\) with zero boundary values and with bounded total \(m\)-Hessian mass \

Origin of broadband acoustic emission from a dancing cavitation bubble
Applied Physics ExpressAcoustic cavitation generates bubbles exhibiting violent expansion and contraction under intense ultrasound in liquids. The acoustic emissions (AE) spectrum from cavitation bubbles contains harmonics, subharmonics, ultraharmonics, and broadband noise ...

Emergence of subharmonics in a microwave driven dissipative Rydberg gas
Physical Review ResearchQuantum many-body systems near phase transitions respond collectively to externally applied perturbations. We explore this phenomenon in a laser-driven dissipative Rydberg gas that is tuned to a bistable regime.
