Some properties of frames of subspaces obtained by operator theory methods
(Academic Press Inc Elsevier Science, 2008-07-01)
We study the relationship among operators, orthonormal basis of subspaces and frames of subspaces (also called fusion frames) for a separable Hilbert space H. We get sufficient conditions on an orthonormal basis of subspaces ...

Critical pairs of sequences of a mixed frame potential
(Taylor & Francis, 2014-09)
The classical frame potential in a finite dimensional Hilbert space has been introduced by Benedetto and Fickus, who showed that all finite unit-norm tight frames can be characterized as the minimizers of this energy ...
Stereographic wavelet frames on the sphere
(Academic Press Inc Elsevier Science, 2005-09)
In this paper we exploit the continuous wavelet transform (CWT) on the two-dimensional sphere S2, introduced previously by two of us, to build associated discrete wavelet frames. We first explore half-continuous frames, ...
News framing of cannabis: A quantitative exploratory study from the framing theoryEl enmarcado informativo del cannabis: un estudio cuantitativo exploratorio desde la teoría del framing
(Universidad del Rosario / Universidad de Los Andes / Universidad Complutense de Madrid, 2014)
The journalistic coverage of cannabis, the most used drug of restricted trade in the world, has stimulated a debate about its effects. However, there is a lack of research about the media information on cannabis, and the ...
Eventos legais e sua descrição conforme a semântica de frames
(Universidade do Vale do Rio dos Sinos, 2016-02-29)
According to the demand for increasingly efficient computer systems with respect to information retrieval, as well as the large number of legal sites, ontologies have proved to be useful means of organizing information in ...
