Using otsu's threshold selection method for eliminating terms in vector space model computation
(2013-12-01)
Visualization techniques have proved to be valuable tools to support textual data exploration. Dimensionality reduction techniques have been widely used to produce visual representation of document collections. Focusing ...
Instantaneous Phase Threshold for Reflector Detection in Ultrasonic Images
(Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01)
A method for reflector detection, based on the instantaneous phase of the aperture data for ultrasonic images, is proposed. The instantaneous phase (IP) image is obtained by replacing the amplitude information by the ...
Phantom reflexes: Muscle contractions at a frequency not physically present in the input stimuli
(Elsevier, 2007-09)
In the motor system, the periodic stimulation of one Ia-afferent input produces reflex muscle contractions at the input frequency. However, we observed that when two Ia monosynaptic reflex-afferent inputs are involved the ...
Auditory steady-state response in the first six months of life
(2014)
Objective: To characterize the thresholds of the auditory steady-state response that relates to term newborns and infants. Design: The study was cross-sectional using auditory steadystate response assessment, and the ...

Charge transport in conjugated polymer-semiconductor nanoparticle composite near the percolation threshold
(Springer, 2017-12-01)
This paper describes a new statistical model to predict the frequency dependence of the conductivity of conjugated polymer-semiconductor nanoparticle composites. The model considers AC conduction in an inhomogeneous medium ...
Performance enhancement in OFDM systems with ICI utilizing the improved double jump linear combination pulse
(IEE, 2017)
It is well-know that carrier frequency offset in the subcarriers of orthogonal frequency division multiplexing (OFDM) leads to intercarrier interference (ICI); therefore, system degradation occurs. Nevertheless, this issue ...
