Electronic shelf labeling employing visible light communication concepts
2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP), 2014This paper discusses the usage of visible light communication concepts for Electronic Shelf Labeling Devices (ESLD), using unmodified smart phones. Visible light communication enables novel and interesting approaches to the design of these devices, able to address application scenarios that have not yet been explored. Amongst these novel approaches, it

Abstract The present paper deals with the influence of light shelf and model reflectance on light shelf performance. The variation with the day of the year of the mean hourly illuminance values measured at 0.50 m . from a south facing side window in 1 : 10 models has been studied for hours with unit sunshine fraction σ. The four light shelves

The transmission of sufficient daylight to offset electrical lighting, while maintaining comfortable conditions for occupants, is the central objective for effective daylighting. Utilizing a light shelf is a common strategy for enabling daylight transmission while controlling direct sun and discomfort glare to maintain occupant comfort. ?

Light hydrocarbons in recent Texas continental shelf and slope sediments
Journal of Geophysical Research: Oceans, 1978The distributions of the concentrations of methane, ethene, ethane, propene, and propane in twelve 1‐to 2‐m‐long gravity cores for two transects from nearshore to midslope off the southwest Texas Gulf Coast are reported. Methane profiles exhibit maxima in the top 40 cm of sediment on the shelf, in contrast to downward increasing gradients in the slope ...
