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 ...
Robust voice activity detection algorithm using spectrum estimation and dynamic thresholding
(IEEE Computer Society, 2009)
An algorithm for voice activity detection (VAD) is presented in this paper, it uses the classical short time fourier transform (STFT) followed by dynamic thresholding over the noise floor which allows accurate determination ...
The Lyapunov spectrum as the Newton method
(ELSEVIER SCIENCE BV, 2012)
For a class of dynamical systems, the cookie-cutter maps, we prove that the Lyapunov spectrum coincides with the map given by the Newton-Raphson method applied to the derivative of the pressure function. (C) 2012 Elsevier ...
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 ...

THE INCLUSION OF THE STUDENT WITH AUTISTIC SPECTRUM DISORDER IN THE CLASSROOM
(Unesp-faculdade Ciencias & Letras, 2018-12-01)
The educational inclusion of children and young people with autism spectrum disorders (ASD) has been a challenge for all those involved in the educational process, nowadays and has been the goal for educational public ...

Electrical load forecasting in disaggregated levels using Fuzzy ARTMAP artificial neural network and noise removal by singular spectrum analysis
(2020-07-01)
Electrical load forecasting in disaggregated levels is a difficult task due to time series randomness, which leads to noise and consequently affects the quality of predictions. To mitigate this problem, noise removal using ...
