Load Losses and Short-Circuit Resistances of Distribution Transformers According to IEEE Standard C57.110

open access: yesInventions, 2023
Load losses determine transformers’ efficiency and life, which are limited by overheating and deterioration of their elements. Since these losses can be characterized by short-circuit resistances, in this article, we have developed expressions for the ...

Chord-Conditioned Melody Harmonization With Controllable Harmonicity

open access: yesICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023
Melody harmonization has long been closely associated with chorales composed by Johann Sebastian Bach. Previous works rarely emphasised chorale generation conditioned on chord progressions, and there has been a lack of focus on assistive compositional tools.

Lorentz Harmonics, Squeeze Harmonics and Their Physical Applications [PDF]

open access: yesSymmetry, 2011
Among the symmetries in physics, the rotation symmetry is most familiar to us. It is known that the spherical harmonics serve useful purposes when the world is rotated. Squeeze transformations are also becoming more prominent in physics, particularly in optical sciences and in high-energy physics.

A Comprehensive Survey on Different Control Strategies and Applications of Active Power Filters for Power Quality Improvement

open access: yesEnergies, 2021
Power quality (PQ) has become an important topic in today’s power system scenario. PQ issues are raised not only in normal three-phase systems but also with the incorporation of different distributed generations (DGs), including renewable energy sources,
