Area and the intensity-time relation in the fovea - Karn - 1936 () Citation Context ...uction of a constant photochemical effect. It has been found to apply within well marked limits of exposure to both the fovea and periphery of the human eye, for threshold (Graham and Margaria, 1935;...
Intensity thresholds were determined for red and violet light as a function of the area of the stimulating surface for the periphery of the eye. Measurements with red light were made on the fovea. Results show that the thresholds for both fovea and periphery follow a typical course with an in...

and then identified regional drought events in China using the Intensity–Area–Duration (IAD) method, which considers both temporal continuity and spatial dynamics. On this basis, the spatiotemporal variations in frequency, intensity, duration, and affected area of drought events in China and its ...
The examining and derivation of intensity–duration–frequency (IDF) curves in an urban arid area under a variety of terrain patterns and climatic changes is anticipated. Several flood events have been reported in the Al-Lith region of western Saudi Arabia that took away many lives and caused ...
In subject area: Chemistry 'Infrared signal intensity' refers to the amount of infrared light absorbed by bonds in a substance, such as ethanol in the case of an alcohol sensor. The change in intensity helps determine the concentration of the substance, like ethanol, being analyzed. ...
