Two-Stage Atomic Decomposition of Multichannel EEG and the Previously Undetectable Sleep Spindles [PDF]

open access: yesSensors
We propose a two-step procedure for atomic decomposition of multichannel EEGs, based upon multivariate matching pursuit and dipolar inverse solution, from which atoms representing relevant EEG structures are selected according to prior knowledge.

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

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

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.

Atomic Formulation of the Boolean Curve Fitting Problem [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2022
Boolean curve fitting is the process of finding a Boolean function that takes given values at certain points in its Boolean domain. The problem boils down to solving a set of ‘big’ Boolean equations that may or may not be consistent.

On generalized Hardy spaces associated with singular partial differential operators

open access: yesCubo, 2023
We define and study the Hardy spaces associated with singular partial differential operators. Also, a characterization by mean of atomic decomposition is investigated.

Approximative K-atomic decompositions and frames in Banach spaces [PDF]

open access: yesArab Journal of Mathematical Sciences, 2020
L. Gǎvruţa (2012) introduced a special kind of frames, named K-frames, where K is an operator, in Hilbert spaces, which is significant in frame theory and has many applications.

A Smart Noise Jamming Suppression Method Based on Atomic Dictionary Parameter Optimization Decomposition

open access: yesRemote Sensing, 2022
Smart noise jamming is a new jamming style against radar, which plays an important role in modern radar electronic warfare. In order to solve the complex problem of convolutional smart noise jamming suppression with different time delay and jamming ...

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.

Variable Anisotropic Hardy Spaces with Variable Exponents

open access: yesAnalysis and Geometry in Metric Spaces, 2021
Let p(·) : ℝn → (0, ∞] be a variable exponent function satisfying the globally log-Hölder continuous and let Θ be a continuous multi-level ellipsoid cover of ℝn introduced by Dekel et al. [12].
