Very low frequency three-dimensional beamforming for a miniaturized aperture acoustic vector sensor array [PDF]
JASA Express Letters, 2022 In this Letter, a three-dimensional beamforming method is proposed for a miniaturized aperture acoustic vector sensor (AVS) array. This method extracts the multipole modes using the AVS array, and then synthesizes the desired beam pattern according to ...

Spherical harmonics coefficients for ligand-based virtual screening of cyclooxygenase inhibitors. [PDF]
PLoS ONE, 2011 Molecular descriptors are essential for many applications in computational chemistry, such as ligand-based similarity searching. Spherical harmonics have previously been suggested as comprehensive descriptors of molecular structure and properties.

Robust Object Classification Approach Using Spherical Harmonics
IEEE Access, 2022 Point clouds produced by either 3D scanners or multi-view images are often imperfect and contain noise or outliers. This paper presents an end-to-end robust spherical harmonics approach to classifying 3D objects.

Sultan Qaboos University Journal for Science, 2012 In a recent paper (Nasir, 2007), a set of weakly orthogonal and completely orthogonal spherical harmonics in a non-polar spherical coordinate system based on a cubed-sphere was constructed. In this work, we explore some linear relations between these two

Modeling of Ionospheric Delay for SBAS Using Spherical Harmonics Functions [PDF]
TransNav, 2013 In SBAS (satellite-based augmentation system), it is important to estimate ionospheric delay accurately to guarantee user's accuracy and integrity. Grid based ionospheric models are generally used to estimate ionospheric delay for SBAS.

A fuzzy bipolar celestial sphere
Journal of High Energy Physics, 2019 We introduce a non-commutative deformation of the algebra of bipolar spherical harmonics supporting the action of the full Lorentz algebra. Our construction is close in spirit to the one of the non-commutative spherical harmonics associated to the fuzzy ...

An alternative to Wigner d-matrices for rotating real spherical harmonics
AIP Advances, 2013 Transformation of spherical harmonics under rotation is a major problem in many areas of theoretical and applied science. While elegantly and efficiently solved for complex spherical harmonics with Wigner D- and d-matrices, extending this method to real ...

New class of solutions to Laplace equation: Regularized multipoles of negative orders
Physical Review Research, 2019 We introduce a new class of solutions to the Laplace equation, dubbed logopoles, and use them to derive a new relation between solutions in prolate spheroidal and spherical coordinates.
