pulses of 20 cycles per second as stimulation. The stimulus voltage was increased from zero at a constant rate of 80mV per second to determine the threshold S1 for the appearance of flicker, and then the threshold S2 for the disappearance was determined by lowering the voltage from a sufficiently high level at the same rate as above. The difference of the thresholds S1-S2 at rest was chosen as ...

Industrial Static Var Generator (SVG) is typically applied at or near the load center to mitigate voltage fluctuation, flicker, phase unbalance, non-sine distortion or other load-related disturbance. Special attention is paid to the influence of grid voltage quality on SVG current, the non-sine distortion and unbalance of grid voltage causes not only the AC current distortion and unbalance but ...

Recently utilities and end users become more concerned about power quality issues because the load equipments are more sensitive to various power quality disturbances, such as harmonics and voltage fluctuation. Harmonic distortion and voltage flicker are the major causes in growing concern about electric power quality. Power quality disturbance monitoring plays an important role in the deregula...

The VIIRS day/night band (DNB) high gain stage (HGS) pixel effective dwell time is in the range of 2–3 milliseconds (ms), which about one third flicker cycle present lighting powered by alternating current. Thus, if present, it induces random fluctuations nightly DNB radiances. This results increased variance temporal profiles. A survey characteristics conducted with high-speed camera data coll...

Arc furnaces can be classified as electricity receivers, which largely affect the quality of in power system. Voltage fluctuations are main disturbance generated by arc furnaces. The effects voltage include phenomenon flickering light. Apart from fluctuations, devices, to a lesser extent, source current and asymmetry, curve distortion, dips. purpose theoretical considerations is assess article ...

A technique that relies on integer wavelets to deliver energy to pixels and display gray shades in rms responding matrix displays is proposed. A large number of gray shades can be displayed without flicker using simple addressing waveforms with a few voltage levels.

There is an increasing interest in monolithic integration for wireless transceivers. This integration can be made possible with the advantages of direct conversion techniques. However, DC offset and flicker noise become critical to the system. In this paper, we propose a wide tuning range and high gain AGC with an effective automatic DC offset cancellation. The proposed AGC and transceiver arch...

We measured foveal flicker sensitivity with and without external added temporal noise at various levels of retinal illuminance and described the data with our model of flicker sensitivity comprising: (i) low-pass filtering of the flickering signal plus external temporal and/or quantal noise by the modulation transfer function (MTF) of the retina (R): (ii) high-pass filtering in proportion to te...

Ribbon synapses mediate continuous release in neurons that have graded voltage responses. While mammalian retinas can signal visual flicker at 80-100 Hz, the time constant, τ, for the refilling of a depleted vesicle release pool at cone photoreceptor ribbons is 0.7-1.1 s. Due to this prolonged depression, the mechanism for encoding high temporal frequencies is unclear. To determine the mechanis...
