Brightening and Dimming Aftereffects at Low and High Luminance

open access: yesVision, 2018
Adaptation to a spatially uniform field that increases or decreases in luminance over time yields a “ramp aftereffect”, whereby a steady, uniform luminance appears to dim or brighten, and an appropriate non-uniform test field appears to move.

Flicker Caused by Operation of Industrial Technology

open access: yesAdvances in Electrical and Electronic Engineering, 2016
There are more and more electrical devices operating in industrial plants which impact negatively on the distribution network. The EN 50160 standard defines the voltage characteristics of electricity supplied by the public distribution system and it is a

Determination of Flicker Contribution Level by Using Proposed Index

open access: yesElektronika ir Elektrotechnika, 2018
Depending on different load characteristics, various power quality disturbances such as sag-swell, harmonics, inter-harmonics, and flicker, appear in electric power systems. Among these power quality disturbances, the flicker is one of the critical power

Time Production Intensively Studied in One Observer

open access: yesJournal for Person-Oriented Research, 2022
If one accepts the notion of an internal clock, then one must further presume that time production (TP) is attuned with the rate of functioning of the clock’s pacemaker.
