Atomic decompositions of audio signals [PDF]

open access: yesProceedings of 1997 Workshop on Applications of Signal Processing to Audio and Acoustics, 2002
Signal modeling techniques ranging from basis expansions to parametric approaches have been applied to audio signal processing. Motivated by the fundamental limitations of basis expansions for representing arbitrary signal features and providing means for signal modifications, we consider decompositions in terms of functions that are both signal ...

Atom decomposition-based intonation modelling [PDF]

open access: yes2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015
Current statistical parametric text-to-speech (TTS) synthesis methods allow production of neutral speech with acceptable quality. However, prosody is often qualified as unsatisfactory and sounding too flat. In this paper, we address intonation modelling for TTS based on physiological aspects of prosody production.

Atomic-scale imaging of CH3NH3PbI3 structure and its decomposition pathway

open access: yesNature Communications, 2021
The knowledge of atomic structure and structural instability of hybrid perovskites is crucial to understand their photoelectric properties and failure mechanism. Here, the authors utilise low-dose TEM imaging technique to investigate the atomic structure

Ultrafine microstructure and hardness in Fe-Cr-Co alloy induced by spinodal decomposition under magnetic field

open access: yesMaterials & Design, 2021
Application of an external magnetic field during heat treatment affects the hardness of magnetic Fe-Cr-Co alloys. The microstructure and composition at atomic scale, as well as the hardening mechanisms need extensive studies. Using atomic resolution STEM,

Modular Structures and Atomic Decomposition in Ontologies

open access: yesJournal of Artificial Intelligence Research, 2020
With the growth of ontologies used in diverse application areas, the need for module extraction and modularisation techniques has risen. The notion of the modular structure of an ontology, which comprises a suitable set of base modules together with their logical dependencies, has the potential to help users and developers in comprehending, sharing ...

The Application of Atom-RQEA in Calculation of Short Term Flicker Severity

open access: yesJournal of Harbin University of Science and Technology, 2017
Short term flicker severity Pst is an important index of evaluating power quality. To improve precision of calculation Atom-RQEA is proposed. The core is to construct atom library in terms of characteristic of voltage fluctuation and flicker, using ...

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.

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.

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 ...
