Polar Alignment and Atomic Decomposition

open access: yesCoRR, 2019
Structured optimization uses a prescribed set of atoms to assemble a solution that fits a model to data. Polarity, which extends the familiar notion of orthogonality from linear sets to general convex sets, plays a special role in a simple and geometric form of convex duality.

Mixed Over-Voltage Decomposition Using Atomic Decompositions Based on a Damped Sinusoids Atom Dictionary

open access: yesEnergies, 2011
The main purpose of this paper is to establish a signal decomposition system aiming at mixed over-voltages in power systems. In an electric power system, over-voltage presents a great threat for the system safety.

Calderón-Hardy type spaces and the Heisenberg sub-Laplacian [PDF]

open access: yesOpuscula Mathematica
For \(0 \lt p \leq 1 \lt q \lt \infty\) and \(\gamma \gt 0\), we introduce the Calderón-Hardy spaces \(\mathcal{H}^{p}_{q,\gamma}(\mathbb{H}^{n})\) on the Heisenberg group \(\mathbb{H}^{n}\), and show for every \(f \in H^{p}(\mathbb{H}^{n})\) that the ...

Spherical Atomic Norm-Inspired Approach for Direction-of-Arrival Estimation of EM Waves Impinging on Spherical Antenna Array with Undefined Mutual Coupling

open access: yesApplied Sciences, 2023
A spherical antenna array (SAA) is an array-designed arrangement capable of scanning in almost all the radiation sphere with constant directivity. It finds recent applications in aerospace, spacecraft, vehicular and satellite communications.

Atomic decomposition for Morrey-Lorentz spaces [PDF]

open access: yes, 2022
In this paper, we consider the atomic decomposition for Morrey-Lorentz spaces and applications. Morrey-Lorentz spaces, which have structures of Morrey spaces, Lorentz spaces and their weak-type spaces, are introduced by M. A. Ragusa in 2012.

Thermal stability of ionic solids: A boiling points survey

open access: yesChemical Thermodynamics and Thermal Analysis, 2023
A survey of those standard inorganic materials which boil without sublimation or decomposition has yielded data for 110 unique materials. These separate according to their ambient lattice energies into groups of monohalides, dihalides, trihalides ...

The atomic decomposition of harmonic functions satisfying certain conditions of integrability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
Distributions on Euclidean spaces with derivatives of their Poisson integral satisfying certain natural conditions of integrability are represented as sums of weighted atoms.

Boundedness of multidimensional Hausdorff operator on Hardy-Morrey and Besov-Morrey spaces

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we establish some boundedness conditions for the multidimensional Hausdorff operator on the homogeneous Hardy-Morrey and on the Besov-Morrey space, and we extend some results in the recent papers by Jia and Wang, and by Mazzucato ...
