On the minimizers of the fusion frame potential
(Wiley VCH Verlag, 2018-03)
We study the minimizers of the fusion frame potential in the case that both the weights and the dimensions of the subspaces are fixed and not necessarily equal. Using a concept of irregularity we provide a description of ...
Oblique Dual Fusion Frames
(Taylor & Francis, 2018-05)
We introduce and develop the concept of oblique duality for fusion frames. This concept provides a mathematical framework to deal with problems in distributed signal processing where the signals considered as elements in ...
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 ...
Optimal dual fusion frames for probabilistic erasures
(Int Linear Algebra Soc, 2017-06)
For any fixed fusion frame, its optimal dual fusion frames for reconstruction is studied in case of erasures of subspaces. It is considered that a probability distribution of erasure of subspaces is given and that a blind ...
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 ...
Dual fusion frames
(Springer, 2014-10)
The definition of dual fusion frame presents technical problems related to the domain of the synthesis operator. The notion commonly used is the analogue to the canonical dual frame. Here a new concept of dual is studied ...
ANÁLISE DESCRITIVO-LEXICAL DO FRAME EXPERIÊNCIA DE DANO CORPORAL SOB A ÓTICA DA SEMÂNTICA DE FRAMES
(Universidade Federal do Espírito SantoBRPrograma de Pós-Graduação em LinguísticaUFESMestrado em Estudos Linguísticos, 2011-12-09)
Esta investigação vincula-se ao Projeto FrameNet Brasil e tem como base teórica a Semântica de Frames, linha de estudos cunhada por Fillmore (2006), cujo postulado central é: as significações lingüísticas são relacionadas ...
