A Digital Technique for Online Identification and Tracking of Power System Harmonics Based on Real Coded Genetic Algorithm

, 2006
Current and voltage waveforms of a distribution or a transmission system are not pure sinusoids. There are distortions in these waveforms that consist of a combination of the fundamental frequency, harmonics and high frequency transients.

Active Currents, Power Factor, and Apparent Power for Practical Power Delivery Systems

IEEE Access, 2020
Concepts of apparent power and power factor as measures of a system's power delivery capability are over a century old but have not been defined in one general, rigorous and acceptable way.

Combination Tones in Violins

Archives of Acoustics, 2013
In this study we investigate the appearance of combination tones in violins. Most authors in recent times have emphasised that combination tones occur inside the ear exclusively (intra-aural).

Processing of harmonics in the lateral belt of macaque auditory cortex

Frontiers in Neuroscience, 2014
Many speech sounds and animal vocalizations contain components, referred to as complex tones, that consist of a fundamental frequency (F0) and higher harmonics. In this study we examined single-unit activity recorded in the core (A1) and lateral belt (LB)

Even-odd harmonics generated from above-threshold ionization

, 2014
We are reporting a theoretical prediction: The photoelectrons forming above-threshold-ionization (ATI) peaks emit both even and odd harmonics. These harmonics exhibit plateau and cut-off features similar to those odd-only harmonics observed in ATI ...
