Riemannian Submersions with Discrete Spectrum
(SPRINGERNEW YORK, 2012)
We prove some estimates on the spectrum of the Laplacian of the total space of a Riemannian submersion in terms of the spectrum of the Laplacian of the base and the geometry of the fibers. When the fibers of the submersions ...
Fractal descriptors based on Fourier spectrum applied to texture analysis
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This work proposes the development and study of a novel technique lot the generation of fractal descriptors used in texture analysis. The novel descriptors are obtained from a multiscale transform applied to the Fourier ...
On the Fucik spectrum for elliptic systems

The Ratio of Independent Arbitrary alpha-mu Random Variables and its Application in the Capacity Analysis of Spectrum Sharing Systems
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2012)
Comment on ‘‘Molecular Structure analysis and Spectroscopic Characterization of Carbimazole with experimental (FT-IR, FT-Raman and UV–Vis) techniques and quantum chemical calculations’’ [J. Mol. Struct. 1052 (2013) 38–49]
(Elsevier Science, 2014-01-06)
The title paper  reports the analysis of the vibrational spectra (infrared and Raman) of solid carbimazole based on the computed molecular structure for a rather unusual conformer. The optimized structure does agree ...
On the Fucik spectrum of the Laplacian on a torus
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
We study the Fucik spectrum of the Laplacian on a two-dimensional torus T(2). Exploiting the invariance properties of the domain T(2) with respect to translations we obtain a good description of large parts of the spectrum. ...
A new statistical test based on the wavelet cross-spectrum to detect time-frequency dependence between non-stationary signals: Application to the analysis of cortico-muscular interactions
The study of the correlations that may exist between neurophysiological signals is at the heart of modern techniques for data analysis in neuroscience. Wavelet coherence is a popular method to construct a time-frequency ...
Methacycline: A Review of Analytical Methods
(Bentham Science Publ Ltd, 2012-02-01)
Methacycline is a broad spectrum, semisynthetic antibiotic prepared from oxytetracycline. Its antibacterial spectrum is as same as that of tetracycline, but its efficacy is superior to that of oxytetracycline and tetracycline. ...
ON THE ESSENTIAL SPECTRUM OF A SEMIGROUP OF THERMOELASTICITY
(Pergamon-elsevier Science LtdOxfordInglaterra, 1993)
