Spectrum of J-frame operators [PDF]
Opuscula Mathematica, 2018 A $J$-frame is a frame $\mathcal{F}$ for a Krein space $(\mathcal{H}, [\, , \,])$ which is compatible with the indefinite inner product $[\, , \, ]$ in the sense that it induces an indefinite reconstruction formula that resembles those produced by orthonormal bases in $\mathcal{H}$.

FRAME DEPENDENCE OF THE ELECTRIC FIELD SPECTRUM OF SOLAR WIND TURBULENCE [PDF]
The Astrophysical Journal, 2011 We present the first survey of electric field data using the ARTEMIS spacecraft in the solar wind to study inertial range turbulence. It was found that the average perpendicular spectral index of the electric field depends on the frame of measurement. In the spacecraft frame it is -5/3, which matches the magnetic field due to the large solar wind speed

Spectrum-Adapted Tight Graph Wavelet and Vertex-Frequency Frames [PDF]
IEEE Transactions on Signal Processing, 2015 We consider the problem of designing spectral graph filters for the construction of dictionaries of atoms that can be used to efficiently represent signals residing on weighted graphs. While the filters used in previous spectral graph wavelet constructions are only adapted to the length of the spectrum, the filters proposed in this paper are adapted to

Bound state spectrum of the massive Thirring model in a rest frame [PDF]
Physical Review D, 2002 The bound state spectrum of the massive Thirring model is studied in the framework of the canonical quantization in the rest frame. First, we quantize the field with the massless free fermion basis states. Then, we make a Bogoliubov transformation. This leads to the natural mass renormalization. The bound state spectrum is analytically solved by the $q\

S-spectrum and associated continuous frames on quaternionic Hilbert spaces
Journal of Geometry and Physics, 2015 As needed for the construction of rank $n$ continuous frames on a right quaternionic Hilbert space the so-called S-spectrum of a right quaternionic operator is studied. Using the S-spectrum, as for the case of complex Hilbert spaces, along the lines of the arguments of {\em Ann.Phys.}, {\bf 222} (1993), 1-37., various classes of rank $n$ continuous ...

Managing dose-, damage- and data-rates in multi-frame spectrum-imaging [PDF]
Microscopy, 2018 As an instrument, the scanning transmission electron microscope is unique in being able to simultaneously explore both local structural and chemical variations in materials at the atomic scale. This is made possible as both types of data are acquired serially, originating simultaneously from sample interactions with a sharply focused electron probe ...

Constructing finite frames of a given spectrum and set of lengths
Applied and Computational Harmonic Analysis, 2013 When constructing finite frames for a given application, the most important consideration is the spectrum of the frame operator. Indeed, the minimum and maximum eigenvalues of the frame operator are the optimal frame bounds, and the frame is tight precisely when this spectrum is constant.

Study on the frame load spectrum combining mileage and percentile extrapolation [PDF]
MATEC Web of Conferences, 2018 In order to get the load spectrum that reflects the actual operation condition of agricultural machinery, this paper proposes to compile the load spectrum of frame by combining the method of load mileage extrapolation and percentile extrapolation. In this paper, the research object was carried out in the frame of vegetable tool carrier to study load ...
