to effectively design daylight in buildings, daylight availability data are necessary. although there is a great potential for daylight energy in iran, its use has been hampered by the absence of measured data. in this paper the illuminance data on the vertical south facing surfaces of tehran were estimated using the iesna model. for this propose an illuminance measuring set was used in order t...

background: daylight availability data are essential for designing effectively day lighted buildings. in respect to no available daylight availability data in iran, illuminance data on the south facing vertical surfaces were estimated using a proper method. methods: an illuminance measuring set was designed for measuring vertical illuminances for standard times over 15 days at one hour interval...

To derive an optimal illuminance of nighttime illumination, we conducted an experiment with 7 healthy young individuals and 7 healthy elderly individuals as subjects. After 20 minutes of adaptation to darkness, subjects were exposed to illumination under 5 conditions comprising 0.5 lx, 1 lx, 3 lx, 10 lx, or 30 lx vertical illuminance of the facial region, and heart rate variability (HRV) and el...

Binocular settings of equidistance have been obtained in a two-rod test apparatus that provides realdepth cues. The magnitude of the localization error for a black vertical rod which oscillates in a given frontal plane has been studied as a function of target velocity at each of three specified photopic levels of binocular retinal illuminance. The direction of the localization error was opposit...
