Distinguishing Hemodynamics from Function in the Human LGN Using a Temporal Response Model

open access: yesVision, 2019
We developed a temporal population receptive field model to differentiate the neural and hemodynamic response functions (HRF) in the human lateral geniculate nucleus (LGN).

A Brücke–Bartley effect for contrast [PDF]

open access: yesRoyal Society Open Science, 2018
Accurate derivation of the psychophysical (a.k.a. transducer) function from just-notable differences requires accurate knowledge of the relationship between the mean and variance of apparent intensities.

Detection method of interharmonic pairs-caused voltage peak fluctuation flicker

open access: yesEnergy Reports, 2022
Interharmonics of high frequency will cause voltage’s peak value fluctuation, which will result in flicker of fluorescent lamp and LED lamp. To realize accurate evaluation of the flicker, a method based on multiresolution S-transform is proposed to ...

Investigation of Reactive Power Control Effects on Flicker and Harmonics Emission of a DFIG Wind Turbine [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2013
One of the most important power quality aspects in wind farms is voltage fluctuation or flicker which should be investigated due to the nature of wind speed variations. These variations result in power and voltage fluctuations at the load bus.

Visual discomfort and flicker

open access: yesVision Research, 2017
Flickering lights can be uncomfortable to look at and can induce seizures in observers with photosensitive epilepsy. However, the temporal characteristics contributing to these effects are not fully known. In the spatial domain, one identified source of visual discomfort is when images have Fourier amplitude spectra that deviate from the natural (∼1 ...
