The Talbot-Plateau law fails for flicker detected by the short-wavelength-sensitive (S) cones: a 30-40 Hz target, flickering too fast for the flicker to be resolved, looks more yellow than a steady target of the same average intensity. The color change, which is produced by distortion at an early compressive nonlinearity, was used to reveal a slightly bandpass S-cone temporal response before th...

The bulk of the video content available today over the Internet and over mobile networks suffers from many imperfections caused during acquisition and transmission. In the case of user-generated content, which is typically produced with inexpensive equipment, these imperfections manifest in various ways through noise, temporal flicker and blurring, just to name a few. Imperfections caused by co...

Fast fluctuations in wind farm power produce voltage flicker the network. One way to mitigate is place a static VAr compensator (SVC). Due operating delay of SVCs, it essential predict reactive power. Here, novel fuzzy nonlinear modeling approach suggested and used one-step-ahead prediction characteristics. The base developed Takagi-Sugeno representation dual-unscented Kalman filter (D-UKF). In...

20 Flicker perception was investigated using two-alternative forced-choice detection and discrimination tasks with four different 21 types of external noise: (1) broadband noise, (2) 5-Hz notched-noiseVbroadband noise with a 5-Hz band centered on the 22 signal frequency removed, (3) 10-Hz notched-noise, and (4) no external noise. The signal was a burst of 10-Hz sinusoidal 23 flicker presented i...

Permeant ions can have significant effects on ion channel conformational changes. To further understand the relationship between ion occupancy and gating conformational changes, we have studied macroscopic and single-channel gating of BK potassium channels with different permeant monovalent cations. While the slopes of the conductance-voltage curve were reduced with respect to potassium for all...

By means of intracellular microelectrode techniques, we have measured the dynamics of the several processes which translate light stimulation into spike activity in the Limulus eye. The transductions from light to voltage and from voltage to spike rate, and the lateral inhibitory transduction from spike rate to voltage, we have characterized by transfer functions. We have checked the appropriat...

In order to solve the problem of voltage flicker produced by electric arc furnace (EAF) operation, it is a prerequisite to analyze the characteristics of voltage time series acquired from AC EAF power supply grid and to conduct voltage prediction based on chaos theory. In this paper, the voltage time series is firstly reconstructed in phase space to determine optimal delay time and embedding di...
