Identification of flicker sources is necessary to find who responsible for the measured and improve power quality. This paper puts forward a new method identifying with minimum measurement units. Contrary previous works where are considered single-frequency signal, autoregressive moving average (ARMA) used model active reactive variations. First, envelope network voltage at busbars derived by H...

Endothelial dysfunction is a key pathogenic mechanism of CVD. The retinal microvascular network offers a unique, non-invasive window to study endothelial function. Recently, dynamic measurement of retinal vessel caliber using flicker light stimulation has been used to evaluate potential endothelial dysfunction and other mechanisms in CVD. A variety of studies now indicate that retinal vasodilat...

Voltage flicker problems have long existed in several of the distribution areas served by the Taiwan Power Company. In the past, those research results indicating that the estimated 10 V Δ value based on the conventional method is significantly smaller than the survey value. This paper is used to study the relationship between the voltage flicker problems and harmonic power variation for the po...

The assessment of flicker fusion frequency (FFF), the stimulus frequency at which a flickering light stimulus can no longer be resolved and appears continuous, and critical flicker fusion frequency (CFF; the highest frequency at any light intensity that an observer can resolve flicker) are useful methods for comparing temporal resolution capabilities between animals. Behavioural experiments hav...

Aliasing effects due to time-discrete capturing of amplitude-modulated light with a digital image sensor are perceived as flicker by humans. Especially when observing these artifacts in mirror replacement systems, they annoying and can pose risk. Therefore, ISO 16505 requires flicker-free reproduction for 90 % people systems. Various psychophysical studies investigate the influence large...

In this paper, we present problems connected with voltage fluctuations in low-voltage networks caused by small PV sources installed an LV network. For the purpose of analysis, high-resolution data gathered at output real for 4 months 2 locations are used. Data processed to analyze impact different network parameters on and flicker. The resulting values flicker given so assessment can be made be...

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...
