A fast approach for overcomplete sparse decomposition based on smoothed L0 norm

open access: yes, 2008
In this paper, a fast algorithm for overcomplete sparse decomposition, called SL0, is proposed. The algorithm is essentially a method for obtaining sparse solutions of underdetermined systems of linear equations, and its applications include ...

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 ...

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

From Frazier-Jawerth characterizations of Besov spaces to Wavelets and Decomposition spaces

open access: yes, 2016
This article describes how the ideas promoted by the fundamental papers published by M. Frazier and B. Jawerth in the eighties have influenced subsequent developments related to the theory of atomic decompositions and Banach frames for function spaces ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Atomic-Level Structural Dynamics of Polyoxoniobates during DMMP Decomposition

open access: yesScientific Reports, 2017
Ambient pressure in situ synchrotron-based spectroscopic techniques have been correlated to illuminate atomic-level details of bond breaking and formation during the hydrolysis of a chemical warfare nerve agent simulant over a polyoxometalate catalyst ...

Weak Orlicz-Hardy Martingale Spaces [PDF]

open access: yes, 2013
In this paper, several weak Orlicz-Hardy martingale spaces associated with concave functions are introduced, and some weak atomic decomposition theorems for them are established.

Atomic Decomposition via Projective Group Representations

open access: yesRocky Mountain Journal of Mathematics, 1996
This paper gives a survey of the Feichtinger-Gröchenig theory combined with a generalization to projective representation. The author also points out the connections to the existing theory for frame decomposition. The main part is given in Section 6. Here the atomic decomposition theorem is stated. He also shows how to construct coherent Hilbert frames

Spinodal Decomposition of Atomic Nuclei [PDF]

open access: yes, 1996
During the multifragmentation of atomic nuclei it seems that identical (or almost identical) initial conditions are leading to very different partitions of the system in interaction. In such a case it is necessary to develop approaches that are able to describe the observed diversity of the final channels. On the other hand the multifragmentation being

Atomic decomposition of characters and crystals

open access: yesAdvances in Mathematics, 2021
Lascoux stated that the type A Kostka-Foulkes polynomials K_{lambda,mu}(t) expand positively in terms of so-called atomic polynomials. For any semisimple Lie algebra, the former polynomial is a t-analogue of the multiplicity of the dominant weight mu in the irreducible representation of highest weight lambda.
