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 ...
Impedance-based structural health monitoring under low signal-to-noise ratio conditions
(2018-01-01)
One of the most promising nondestructive evaluation (NDE) in structural health monitoring (SHM) systems for the inspection of aerospace and civil components is the impedance-based method. This damage detection technique ...
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 ...
Open AccessArticle Impact of the Noise on the Emulated Grid Voltage Signal in Hardware-in-the-Loop Used in Power Converters
This work evaluates the impact of the input voltage noise on a Hardware-In-the-Loop (HIL) system used in the emulation of power converters. A poor signal-to-noise ratio (SNR) can compromise the accuracy and precision of ...
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 ...
Optimization methods applied to nonlinear signal interference models
(2014-01-01)
In wireless mesh networks, it is important to establish the transmission capacity of the links, taking into account the presence of noise that interferes with the transmission and consequently degrades the signal sent from ...
Measurement of stress waves propagation velocities in solid media using wavelet transforms
(Sao Paulo: ABEN, 2005, 2014)
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 ...
Low voltage and variable-pressure scanning electron microscopy of fractured composites
(Pergamon-Elsevier B.V. Ltd, 2014)
