This paper describes the development of a technique for extrapolation of dynamic daylighting simulations from a limited number of high dynamic range photographs. This technique allows us to photographically capture and measure per-pixel lighting quantities from existing spaces in a limited time frame; and the measured information is used to establish a statistics based daylight coefficient mode...

This paper presents the relationship between daylighting performance and shading device design in the perimeter area of buildings. In the area of tropic and sub-tropic, designers always face with the contradiction between solar heat gain and daylighting using. Factors such as different type of shading device, material reflectance, fenestration design, opening ratio, and daylight distribution wi...

Time-series measurements of daylight (skylight plus direct sunlight) spectra beneath overcast skies reveal an unexpectedly wide gamut of pastel colors. Analyses of these spectra indicate that at visible wavelengths, overcasts are far from spectrally neutral transmitters of the daylight incident on their tops. Colorimetric analyses show that overcasts make daylight bluer and that the amount of b...

nifedipine (nif) a 1, 4-dihydropyridine calcium channel antagonist, undergoes photodegradation to nitroso analogues of dehydronifedipine (ndnif) when exposed to sunlight. photodegradation products of nif have no clinical activity, so different formulations of nif must remain unchanged. if nif preparations become unstable in exposure to light, they could cause therapeutic failure. the present st...

This paper analyzes the effects of daylight and daylight saving time (DST) on pedestrian and motor vehicle occupant fatalities in the United States. Multivariate analyses of county level data from the Fatality Analysis Reporting System for 2-week periods in 1998 and 1999 are used. Results show that full year daylight saving time would reduce pedestrian fatalities by 171 per year, or by 13% of a...
