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.

On an atomic decomposition in Banach spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established.

Harmonic mitigation potential of shunt harmonic impedances [PDF]

open access: yesElectric Power Systems Research, 2003
Abstract Although complete compensation is only possible using true active filters, shunt harmonic impedances (SHI) have been shown to provide a considerable reduction of the harmonic propagation. In this paper, the mitigation potential of different SHI is investigated, together with their VA-rating. It is shown that a resistive impedance of 1 pu for

Analysis of arbitrary tooth profiles of cylindrical gears using normal polar coordinates (Application to the generation of a gear tooth profile by a given tooth profile of rack cutter and its interference problem)

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
Various coordinate systems have been used in tooth profile analysis for cylindrical gears. An effective approach to tooth profile expression using normal polar coordinates is proposed.

Coupling microstrip line bandpass filter applied to hybrid frequency synthesizers

open access: yesDianzi Jishu Yingyong, 2018
This paper designs a parallel coupled microstrip bandpass filter at the ends of the hybrid frequency synthesizer of PLL+DDS mixing in the outside of the feedback loop systems. This filter is used to suppress the frequency synthesizer′s spurs and harmonic

Capturing Long-Range Dependence and Harmonic Phenomena in 24-Hour Solar Irradiance Forecasting: A Quantile Regression Robustification via Forecasts Combination Approach

open access: yesIEEE Access, 2020
The global horizontal irradiance data recorded at the earth's horizontal surface is a mixture of deterministic (extra-terrestrially) and stochastic components due to the ever-changing atmospheric conditions. The Box-Jenkins short memory stochastic models

Hericium ophelieae sp. nov., a novel species of Hericium (Basidiomycota: Russulales, Hericiaceae) from the Southern Afrotemperate forests of South Africa

open access: yesMycology, 2023
A novel species of Hericium was recently collected in the Afrotemperate forests (Knysna – Amatole region) of Southern Africa. The novel species shares many similar, dentate features common to other species in Hericium, and its basidiome first appears ...
