Daylight Illumination required to Clerical Work

A Hardware Accelerated Adaptive Mesh Subdivision for Interactive Daylight Illumination

Daylight simulation for generic environments involves visibility computations from an infinite area light source (the sky). In order to obtain accurate results, this task tends to be very time consuming and also requires a good model discretization that is not automatically done in general. This paper presents a daylight simulation method for interactive direct lighting visualization that perfo...

Alternatives to Outdoor Daylight Illumination for Photodynamic Therapy—Use of Greenhouses and Artificial Light Sources

Daylight-mediated photodynamic therapy (daylight PDT) is a simple and pain free treatment of actinic keratoses. Weather conditions may not always allow daylight PDT outdoors. We compared the spectrum of five different lamp candidates for indoor "daylight PDT" and investigated their ability to photobleach protoporphyrin IX (PpIX). Furthermore, we measured the amount of PpIX activating daylight a...

Work-related accidents and daylight saving time in Finland.

BACKGROUND Recent research has indicated that transitions into and out of daylight saving time (DST) unbalance the physiological circadian rhythm and may lead to sleep disturbance. Sleep deprivation may have negative effects on motivation, attention and alertness and thus it is possible that transitions into and out of DST may increase accident rates. AIMS To explore the impact of DST transit...
