The effect of noise variation over time and between populations on the fine spectrotemporal characteristics of different vocalization types
(2021-01)
Noise affects the recognition of acoustic signals by masking information. To compensate for increased noise, individuals often increase the minimum frequency of their vocalization to reduce noise interference. Our goal was ...
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 ...

Velocity Variability in MRI Phase-Contrast
(IEEE, 2018)
MRI phase contrast is a well known technique for computing the average velocity associated to each pixel. In this work, we calculate the exact probability distribution function for the velocity given the noise in the signal. ...

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 ...
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 ...
Modulation Optimization for Achieving Energy Efficient Communications over Fading Channels
(IEEE, 2012)
It is commonly assumed that the energy consumption of wireless communications is minimized when low-order modulations such as BPSK are used. Nevertheless, the literature provides some evidence that low-order modulations ...
