Neural Oscillation Associated with Contagious Itch in Patients with Atopic Dermatitis
Objective: Itch is an unpleasant sensation associated with an urge to scratch and is a major health care issue associated with atopic dermatitis (AD). Contagious itch, i.e., subjective feelings of itchiness induced by watching others’ scratching behavior,

Time-Frequency Analysis of Systems with Changing Dynamic Properties [PDF]
The Wigner-Ville Distribution, and related refinements, represent a class of advanced time-frequency analysis tools that are distinguished from Fourier and wavelet methods by an increase in resolution in the time frequency plane. Time-frequency analysis

Railway wheel-flat and rail surface defect modelling and analysis by time–frequency techniques [PDF]
Damage to the surface of railway wheels and rails commonly occurs in most railways. If not detected, it can result in rapid deterioration and possible failure of rolling stock and infrastructure components causing higher maintenance costs.

Harmonic analysis of AC-bus voltage in converter station based on time–frequency transformation
The disturbance of the AC system has become one of the main causes of commutation failure in the high voltage direct current (HVDC) transmission system. Here, the time–frequency transformation method is used to analyse the AC-bus voltage disturbance from

A choice reaction time analysis of spatial frequency discrimination [PDF]
Simple reaction time to the onset of sinewave gratings was measured as a function of spatial frequency in two observers. These results are compared to the choice reaction time required for the observer to correctly discriminate the spatial frequency of ...

LEAST SQUARES MULTI-WINDOW EVOLUTIONARY SPECTRAL ESTIMATION
We present a multi-window method for obtaining the time-frequency spectrum of non-stationary signals such as speech and music. This method is based on optimal combination of evolutionary spectra that are calculated by using multi-window Gabor expansion ...
