Specific search terms for risk factors included alcohol, wine, spirit, beer, seatbelt, helmet, head protective device, sleep, fatigue, apnoea, conspicuity, visibility, illumination, visual, headlights, light, colour, contrast.
Longer exposures or the use of more powerful lights to boost contrast does not improve their visibility as light reflected from the bones and soft tissues can washout the image.
Even then, the assigned colors serve specific purposes, like bringing out a nebula's chemical structures or improving visibility in light and dark areas.
The walking speeds in non-irritant smoke were measured for extinction coefficients in the range of 0.5 1.1 m-1, which corresponds to approximately 2 4 m of visibility (for light reflecting signs).
The company also flagged a list of factors outlined in the user manual of the Model S that can impair the performance of autopilot, including poor visibility, bright light (oncoming headlights or direct sunlight), damage or obstructions caused by mud, ice, snow and extremely hot or cold temperatures.
Delta officials said the airline operated its last scheduled flight to and from San Juan "armed with the latest forecast from the airline's meteorology team". Flight 431 arrived a minute after noon to nine miles of visibility and light rain, the airline said.
Above that thickness loses in visibility and light conditions make it difficult to distinguish small textures in detail.
Underwater images are essentially characterized by their poor visibility because light is exponentially attenuated as it travels in the water and the scenes result poorly contrasted and hazy.
Better visibility and light conditions, variation in thickness of the thin sections and the possibility to combine fluid inclusion studies with microfossil studies lead to a wide range of advantages over ordinary thin sections.
