Signal-to-noise ratio constrained feedback control: discrete-time robust stability analysis
(IET Control Theory and Applications, 2020)
Regression-Based Noise Modeling for Speech Signal Processing
(2021-01-01)
Speech processing systems are very important in different applications involving speech and voice quality such as automatic speech recognition, forensic phonetics and speech enhancement, among others. In most of them, the ...
Low voltage and variable-pressure scanning electron microscopy of fractured composites
(Pergamon-Elsevier B.V. Ltd, 2012-10-01)
Uncoated fracture surfaces of carbon-epoxy composites are investigated using a variable-pressure environmental scanning electron microscope (VP-ESEM), under optimized conditions for topographic description, image quality ...

Fluorescence Fluctuations and Equivalence Classes of Ca2+ Imaging Experiments
(Public Library Of Science, 2014-04)
Ca2z release into the cytosol through inositol 1,4,5-trisphosphate receptors (IP3Rs) plays a relevant role in numerous physiological processes. IP3R-mediated Ca2z signals involve Ca2z-induced Ca2z-release (CICR) whereby ...
Radon transform-based microseismic event detection and signal-to-noise ratio enhancement
(Elsevier Science, 2015-02)
We present an adaptive filtering method to denoise downhole microseismic data. The methodology uses the apex-shifted parabolic Radon transform. The algorithm is implemented in two steps. In the first step we apply the ...
Simultaneous optical signal-to-noise ratio and differential group delay monitoring based on degree of polarization measurements in optical communications systems
(OPTICAL SOC AMERWASHINGTON, 2012)
We present a simultaneous optical signal-to-noise ratio (OSNR) and differential group delay (DGD) monitoring method based on degree of polarization (DOP) measurements in optical communications systems. For the first time ...
Identifying the stiffness and damping of a nonlinear system using its free response perturbed with Gaussian white noise
(2020-05-01)
Measurement uncertainty can affect the accuracy of estimating parameters of vibrating systems. This article is concerned with the development of a method for estimating parameters from the free vibration response of a ...
Improving performance of spectral subtraction in speech recognition using a model for additive noise
