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

Chord-Conditioned Melody Harmonization With Controllable Harmonicity
ICASSP 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 bases from cosines in Lebesgue spaces with variable summability index
Journal of Inequalities and Applications, 2016 In this paper the perturbed system of cosines is considered. Under certain conditions on the summability index p ( ⋅ ) $p (\cdot )$ and perturbation, the basicity of this system in Lebesgue spaces L p ( ⋅ ) ( 0 , π ) $L_{p (\cdot )} (0,\pi )$ with ...

Harmonic Voltage Synchronization Using GPS Modules for Grid-Connected Power Converters
IEEE Open Journal of Power Electronics, 2022 Voltage-controlled inverters (VCI) for distributed energy resources allow operation in grid-connected and islanded conditions. Common techniques based on $P$-$f$, $Q$-$V$ droop-control use sinusoidal voltage references for the VCIs, which brings unwanted

Harmonic Morphisms Projecting Harmonic Functions to Harmonic Functions [PDF]
Abstract and Applied Analysis, 2012 For Riemannian manifolds M and N, admitting a submersion ϕ with compact fibres, we introduce the projection of a function via its decomposition into horizontal and vertical components. By comparing the Laplacians on M and N, we determine conditions under which a harmonic function on U = ϕ−1(V) ⊂ M projects down, via its horizontal component, to a ...

Harmonic diffeomorphisms of noncompact surfaces and Teichmüller spaces [PDF]
, 2002 Let g : M -> N be a quasiconformal harmonic diffeomorphism between noncompact Riemann surfaces M and N. In this paper we study the relation between the map g and the complex structures given on M and N.

Harmonic Index and Harmonic Polynomial on Graph Operations [PDF]
Symmetry, 2018 Some years ago, the harmonic polynomial was introduced to study the harmonic topological index. Here, using this polynomial, we obtain several properties of the harmonic index of many classical symmetric operations of graphs: Cartesian product, corona product, join, Cartesian sum and lexicographic product.
